I want to add elements by the browser into an array with the name $map I wrote the next piece of code for this: <?php $var = $_POST["var"]; function addIntoArray($var) { global $map; if (($var != ".") || ($var != "..")) { array_push($map, $var); echo $var . " succesfully added to the array!"; } return; } ?> The problem though, is not having an error code, but the screen just does not give an output at all while I did make an echo line. Whats going wrong here?

Alright, so I am making a program that when a button that says "yo" for example, will display a prompt when click. If the answer to the prompt is a verb, then the "yo" form of that verb is displayed. So far I have a button, that when clicked has a prompt. When I enter a word in the button I can't make it display the "yo" form of the verb. Please help: Here is my javascript: function verb(verb, yo) { this.verb = verb; this.yo = yo;}//*All verbsvar estar = new verb("estar", "estoy");//*All arraysvar verbs = [estar];//*Verb translation present_yofunction presentYo(){ var verb = verbs; var answer = prompt("Enter a verb: ").toLowerCase(); if (answer == verb){ document.getElementById("translation").innerHTML = "verbs.yo"; } else{ document.getElementById("translation").innerHTML = "I do not know the translation."; } } When I enter a word, all that shows up is "I do not know the translation." Please help. Thanks.

Hello so I made an array and it works fine when you refresh the page the image changes but at lower screen resolutions the image cuts of the edge. With my basic code it worked fine I was wondering what I was doing wrong. This was my old code which was just one image and at lower resolutions it would still fit on the screen <center><img src="my image url" width=47%> </center> But when I use my array it cuts of I want to make the image center and just put width=47% like the top code but not sure where to put it <script language="JavaScript"><!--function random_imglink(){var myimages=new Array()myimages[1]="my image url"myimages[2]="my image url"myimages[3]="my image url"myimages[4]="my image url"myimages[5]="my image url"myimages[6]="my image url"var ry=Math.floor(Math.random()*myimages.length)if (ry==0)ry=1document.write('<img src="'+myimages[ry]+'" width=47%')}random_imglink()//--></script> If you could help me it would be much appreciated

Newbie, first time ever posting. I found this script online and it works exactly as I want with the exception of sorting. On my local host it presents output in alphabetical order, but online it will not. I've tried for days to work it into an array so I could sort it, but have hit my patience wall. Can someone please show me where to insert the array and then read it back? Thanks in advance for any effort put into this topic. George dir-read-script.php

Hi W3, this array-within-array should print out Students 1, 2, 3 and their averaged grades, but it's only printing out Student 3 & average, and no console errors. It works fine substituting console.log, so the problem is my innerHTML part. Thanks in advance for direction. document.addEventListener("DOMContentLoaded", function(){var grades = [[89, 77, 78], [76, 82, 81], [91, 94, 89]];var total = 0;var average = 0.0;for (var row = 0; row < grades.length; row++){ for (var col = 0; col < grades[row].length; col++){ total += grades[row][col];} average = total / grades[row].length; divid = document.getElementById("nice"); divid.innerHTML = 'Student ' + parseInt(row+1) + 'average: ' + average.toFixed(2); total = 0; average = 0.0;}});

Hi everyone. I'm trying to echo the values of an array inside HTML's <option> tag. The following should be echod: <option value="Moose Jaw,SK,Canada">Moose Jaw,SK,Canada</option> <option value="Prince Albert,SK,Canada">Prince Albert,SK,Canada</option> <option value="Regina,SK,Canada">Regina,SK,Canada</option> <option value="Saskatoon,SK,Canada">Saskatoon,SK,Canada</option> The code I attempted was: <!DOCTYPE html> <html> <body> <?php $sk=array("Saskatoon","Regina","Moose Jaw", "Prince Albert"); sort($sk); foreach ($sk as $value) { echo '<option value="'.$value.',SK,Canada">'.$value.',SK,Canada</option>'; echo "<br>"; } ?> </body> </html> Pls. note that the values of the array are not sorted alphabetically. The output, however, should be sorted in ascending format and be within the <option> tag after adding the province and country. Though the select element will be there in the final code, I ignored it here because I am able to manage it separately. I now want to do what I explained only, which I am unable to yet. Any help will be highly appreciated.

I have "Checkbox" input with multiple values. <input type="checkbox" name="drug" value="1" /><input type="checkbox" name="drug" value="2" /><input type="checkbox" name="drug" value="3" /> I want to run through this array and alert() all the values. I'm guessing I should use Jquery's .each() command but I'm not sure how to use it. the problem is, I don't understand how to use it so I can get the key and it's value. $.each($("input[name='drug']"),function(i,v){ alert(i+": "+v);}); What am I missing in the main idea?

So I have a calendar that I created using JavaScript on an HTML page but now I need to create a variable that contains an array. The array needs to be a week long to-do list. Problem 1, I try to create the variable to produce the 'to-do' list but I'm not sure how to associate the array with a week out of the month. Second, I'm not sure where to plug in the variable once I have created it in order to make it show up in the calendar. Below is the script I wrote for the calendar. And help would be appreciated. Thanks! <!doctype html> <html> <head> <meta charset="UTF-8"> <title>Month Calendar</title> </head> <body> <script> monthnames = new Array( "January", "Februrary", "March", "April", "May", "June", "July", "August", "September", "October", "November", "Decemeber"); var linkcount=0; function addlink(month, day, href) { var entry = new Array(3); entry[0] = month; entry[1] = day; entry[2] = href; this[linkcount++] = entry; } Array.prototype.addlink = addlink; linkdays = new Array(); monthdays = new Array(12); monthdays[0]=31; monthdays[1]=28; monthdays[2]=31; monthdays[3]=30; monthdays[4]=31; monthdays[5]=30; monthdays[6]=31; monthdays[7]=31; monthdays[8]=30; monthdays[9]=31; monthdays[10]=30; monthdays[11]=31; todayDate=new Date(); thisday=todayDate.getDay(); thismonth=todayDate.getMonth(); thisdate=todayDate.getDate(); thisyear=todayDate.getYear(); thisyear = thisyear % 100; thisyear = ((thisyear < 50) ?

Hello, new here and also sorta new to PHP and all that. I'm trying to find a way to select certain checkboxes and input that data into a database. And then at times go back and view and update the database. The checkboxes may also change at times and I do not want to go add a bunch of fields into the database just to see who's all in it. What I have so far is peoples names in a checkbox form where I can select names and submit it. It then implodes and inserts it into the database like so responders(2,4,47,56) Its not going to be a thing like responders(0,0,1,0) type thing. My format so I do not confuse people responders = row in mysql (numbers) = data in the field in my row Am I way overthinking this, or is there a very simple way to do this? Please note, the name list may update in the future as in names being added, I would like an easy way to add people without killing myself modifying my php/html files. If I lost you in anyway let me know I will see what I can do to make it not confusing.

I need to loop through an array, in the order that the items appear, and get both the key of the item and its value. I know I can use foreach to loop through an array but as far as I know I can choose between the key and the value of the current item but not get both. Here's an example of an array: <?php$SampleArray = array(55 => "car","2" => "house","boat" => "boat",0 => "engine",666 => "website",);?> It would work somehow like this: loop($SampleArray){ echo key . " - " value . "n";} And the result would be something like:55 - car 2 - house boat - boat 0 - engine 666 - website

Dear reader, On my own server I created the following code that is working perfectly: $items = []; foreach ($rows as $row) { $items[] = [ "item" => $row["item"], "brand" => $row["brand"], "number" => $row["number"], "price" => $row["price"], "start" => $row["start"], "end" => $row["end"], "shop" => $row["shop"], "location" => $row["location"], "link" => $row["link"] ]; } However my hosting party is not supporting php 5.4 and therefor I transformed the code in: $items = array(); foreach ($rows as $row) { $items = array("item" => $row["item"], "brand" => $row["brand"], "number" => $row["number"], "price" => $row["price"], "start" => $row["start"], "end" => $row["end"], "shop" => $row["shop"], "location" => $row["location"], "link" => $row["link"] ); } and now I am getting the error msgs: "Uninitialized string offset: 0". Does anyone knows what I am doing wrong? Thanks inadvance for your help!!!

Good day, I appreciate that this is a popular query but I've been searching the web for answers and I've been unable to get my code to work. I'm trying to create the effect of an animated button on a website. I have a div which contains an <img/>. This image is the "animated button". I have already prepared the additional images to represent the following frames. Now, the JavaScript code I have (which I've pulled together looking at examples) is below. var navAniButton;var aniImgs;var imgAniTimer;var index;var maxImages; function updateVar() {navAniButton = document.getElementById("navAniButton");aniImgs = ["images/Frame1.png", "images/Frame2.png", "images/Frame3.png", "images/Frame4.png", "images/Frame5.png", "images/Frame6.png", "images/Frame7.png", "images/Frame8.png"];imgAniTimer = setInterval(changeAniImg(), 500);index = 0;maxImages = aniImgs.length - 1;} function changeAniImg() {var curAniImg = aniImgs[index];index = (index == maxImages) ? 0 : ++index;navAniButton.src =curAniImg;} The updateVar(); function is called in the body "onload" to update the global variables. When the page is loaded the image src is loaded correctly and then it appears that the JavaScript attempts to change the src, because the image changes to a cross (you know, as if it can't locate the file). But, I can't figure out why it does this. I've opened the debugger and, originally, it advised that the maxImages variable had not been defined. It hadn't. So, I amended that, but now I'm not receiving any errors in the console. I apologise if I've missed something extremely obvious or if I'm omitted something that would help you all out. Let me know if I can help at all.

Hi everyone, I have something like more advanced problem, so I hope someone will help. No need for looking for variables and functions matches, I have good editor, and if there is any, it is because I am translating code to english. Here I have class DBobject, which contains all common database methods, but my focus is on two: public static function find_by_sql($sql) { global $pdo; // pdo connection works fine $query = $pdo->query($sql); $object_array = array(); while($row = $query->fetchAll()) { $object_array[] = static::instantiate($row); } return $object_array; } public static function instantiate($row) { $class = get_called_class(); $object = new $class; // because it can be used for users, pages... I don't wont to repeat my code foreach ($row as $attribute => $value) { $object->$attribute = $value; } return $object; } It is parent class of many classes, and I am looking in the class Comments protected static $table_name='komentari';protected static $db_fields=array(// all of my fields are here);public $id;public $user_id;// and all of database fields as variables And now, when I want to call it... $comment = Comment::find_by_sql(// here I select user based upon id); // this should return object with attributes from my database (because I returned object in instantiate function), am I right?echo $comment->content; // I exept here to echo lorem ipsum dolor sit amet.... And I get error that I called attribute of non-object $comment, aldo I returned the object in instantiate method

Hello all,I have tried so many things to get this to work but to no avail, can someon eplease help me out here with a simple script for n XML steam feed.http://api.steampowered.com/ISteamUserStats/GetGlobalAchievementPercentagesForApp/v0002/?gameid=221380&format=xml OK NOW THE ISSUE IS:I have a blank webpage which I have placed the above link into, I simply want the contents of the XML feed from the link to appear in mypage.......How do I make the contents of that url appear on the same page??SO I NEED THE SMALL SCRIPT OR HTML CODE TO DO THISAlso I would like to have the background a certain colour and use a certain font like 12point arial with bold headings and lower case text.Can someone please provide me with the html to allow this XML feed to appear on my webpage with a different colour background, arial 12pt font inbold and lowercase____________________________________________________________________________I RECEIVED A REPLY TO THIS POST AND THEY ADDED THIS:It's a little hard to tell from what you wrote. But, I think what you are looking for is an AJAX script to pull in the XML,then CSS can take care of the formatting.Look up how to process a XMLHttpRequest in javascript (or another scripting language). That will let you put the XML file into an array. Then,you can use (javascript) document.write() to put the pieces on your page.______________________________________________________________________________SO this being said do I need a javascript code in the page to show the XML Feed with formatting, what would this code be, this is the magicalquestion :)Could someone please please help me..........With regardsMathew

I'm working on a website that I want to be accessible to speakers of many languages but I'm wondering how to architect such a website. I seem to have two options and I hope you guys can help me choose: 1) Database I could make a table that lists all the messages and then have individual language tables with translations of those messages. Each page would then make a dozen or more queries to get all the messages/content to populate each page. I'm a bit worried about what the effect this may have on my databases and whether it is too much for them to handle in addition to all the other queries such as registration, login etc. 2) PHP array Using PHP arrays is also a popular solution. I think both MediaWiki (which drives Wikipedia etc) and phpMyAdmin go with this solution. It's easier to crowd source the translation this way since most people are familiar with pure text files. I'm worried about all the memory that is consumed by this approach and at what point it becomes inviable since every translation gets loaded into memory for every page request.

Hello,I'm new here and to be honest it's the first time I am writing into a Forum. Until now I was only reading through various posts which considerd the same problem as I had. But now I really have no idea what to search and where my problem is. Down here is the PHP Script I have written for a Prom Vote in a nearby school. It would be really great if someone could find my mistake and correct me. <!DOCTYPE html><html lang="en"> <head> <meta charset="utf-8" /> <title></title> </head> <body> <?php$con = mysql_connect("localhost","xxx","xxxxxxxxx");if (!$con) { die('Could not connect: ' . mysql_error()); }mysql_select_db(bgschwechat) or die( "Unable to select database");$abfrage = "SELECT * FROM teilnehmer";$ergebnis = mysql_query($abfrage);$abfrage2 = "SELECT * FROM teilnehmer";$ergebnis2 = mysql_query($abfrage2);echo '<script>';echo 'var stimmzahl = array();';echo 'var name = array();';echo '</script>';while($row = mysql_fetch_object($ergebnis)) { echo '<script>'; echo 'stimmzahl['; echo $row->id; echo '] = 0; '; echo 'name['; echo $row->id; echo '_name'; echo '] = '; echo $row->name; echo '; '; echo 'function '; echo $row->id; echo 'plus() {'; echo 'stimmzahl['; echo $row->id; echo ']++; '; echo 'document.getElementById("'; echo $row->id; echo 'result").innerHTML = stimmzahl['; echo $row->id; echo ']; '; echo '}'; echo 'function '; echo $row->id; echo 'minus() {'; echo 'stimmzahl['; echo $row->id; echo ']--; '; echo 'document.getElementById("'; echo $row->id; echo 'result").innerHTML = stimmzahl['; echo $row->id; echo ']; '; echo '}'; echo '</script>'; } echo '<table class="teilnehmer-liste">'; while($row = mysql_fetch_object($ergebnis2)) { echo '<tr>'; echo '<td>'; echo $row->name; echo '</td>'; echo '<td>'; echo '<button id="'; echo $row->id; echo 'plus" onClick= "function '; echo $row->id; echo 'plus()">+</button>'; echo '</td>'; echo '<td>'; echo '<button id="'; echo $row->id; echo 'minus" onClick=" function '; echo $row->id; echo 'minus()">-</button>'; echo '</td>'; echo '<td>'; echo '<div id="'; echo $row->id; echo 'result">/</div>'; echo '</td>'; echo '</tr>';}mysql_free_result($ergebnis);?></table> </body> </html> The PHP Code works pretty fine but I am not happy with the result because the + and - Buttons don't work :/ Here's the result of the PHP Code in HTML : <!DOCTYPE html><html lang="en"> <head> <meta charset="utf-8" /> <title></title> </head> <body> <script>var stimmzahl = array();var name = array();</script><script>stimmzahl[1] = 0; name[1_name] = Test Person 1; function 1plus() {stimmzahl[1]++; document.getElementById("1result").innerHTML = stimmzahl[1]; }function 1minus() {stimmzahl[1]--; document.getElementById("1result").innerHTML = stimmzahl[1]; }</script><script>stimmzahl[2] = 0; name[2_name] = Test Person 2; function 2plus() {stimmzahl[2]++; document.getElementById("2result").innerHTML = stimmzahl[2]; }function 2minus() {stimmzahl[2]--; document.getElementById("2result").innerHTML = stimmzahl[2]; }</script><table class="teilnehmer-liste"><tr><td>Test Person 1</td><td><button id="1plus" onClick= "function 1plus()">+</button></td><td><button id="1minus" onClick=" function 1minus()">-</button></td><td><div id="1result">/</div></td></tr><tr><td>Test Person 2</td><td><button id="2plus" onClick= "function 2plus()">+</button></td><td><button id="2minus" onClick=" function 2minus()">-</button></td><td><div id="2result">/</div></td></tr></table> </body> </html> It would be really great if someone could help me I need to find a solution as soon as possible because I only have rare time to finish the project.

hi. learnign JavaScript from tutorial provided at http://www.w3schools.com/js/default.asp In JavaScript Array Object section, I was presented with this script: <script>var i;var mycars = new Array();mycars[0] = "Saab";mycars[1] = "Volvo";mycars[2] = "BMW";for (i=0;i<mycars.length;i++){document.write(mycars + "<br>");}</script> I realize that this code says to increase integer value by 1 as long as i<mycars.length But i don't get what is mycars.length in this case? The length of "mycars" (6 characters in this case?) I experimented by adding additional variables: <script>var i;var mycars = new Array();mycars[0] = "Saab";mycars[1] = "Volvo";mycars[2] = "BMW";mycars[3] = "boeing";mycars[4] = "volga";mycars[5] = "airbus";mycars[6] = "tupolev";mycars[7] = "yak";for (i=0;i<mycars.length;i++){document.write(mycars + "<br>");}</script> and i hoped that this addition of new variables will disrupt this function but no, all new variables were displayed properly when i clicked "submit code". Then i changed the function in this place:for (i=0;i=mycars.length;i++) and then immediately my internet browser froze and i had to close it down. So, what kind of length does the mycars.length indicate here and why it's so important that i< mycars.length here? just can't get it

Hello,I want to make a script to check if there is anything drawn on a canvas.I tried to use this script: [/font][font=arial,helvetica,sans-serif]var ctx = document.getElementById("canvas").getContext("2d");[/font][font=arial,helvetica,sans-serif]/* Some other code, including some drawing code[/font][font=arial,helvetica,sans-serif]All drawings are black, with alpha value 255 */[/font] [font=arial,helvetica,sans-serif]var a = ctx.[color=#000000][size=1]getImageData(0,0,room.width,room.height)[/size][/color].data.indexOf(255); // to see if anything is drawn[/font][font=arial,helvetica,sans-serif] But for some reason it didn't work.I have also tested some other array methods, but they didn't work either on the imageData.dataIs there some way to make this work?Using a for loop instead would probably be to slow.
