  1. BACKGROUND: My jubilation was short-lived. For the internal server error that was plaguing my site in general is now plaguing a crucial file in particular. Please find below a file that works perfectly well on my local test server, but fails with an internal server error on my host server. Please also note that the file matomo/index.php is located on the same server as that from which the cURL call is made, but under a different domain name. ini_set('log_errors', 1); ini_set('error_log', dirname(__FILE__) . DIRECTORY_SEPARATOR . 'error.log'); ini_set('html_errors', 0); ini_set('display
  2. BACKGROUND: A visitor arrives on a website. While still on the site he triggers an AJAX call that fills a <div> element with new HTML. Once the page is filled another AJAX call is made that seeks to read the following value as encoded JSON: $_SERVER['REMOTE_REFERER']. Instead I receive a 500 internal server error. The AJAX (function() { $("#main").html(''); $("<link/>", { rel: "stylesheet", type: "text/css", href: "./_utilities/css/yourprofile_filler.css" }).appendTo("head"); $.get('./yourprofile_filler.html', function(data) { $('#main').html(data);
  3. BACKGROUND: I am querying a MySQL database with a Matomo GUI. The API is called imageGraph. The call to the API works, as I have produced the desired image by assigning the URL as the value of an href attribute of an HTML <a> element. When using this link to display the image the image appears on a new page with its own header. This is not the effect that I desire. My goal is to display the image within a <div> tag on a webpage. The code that is suppose to achieve this latter effect is provided below. The URL that fetches the data from the API is identical for both the link
  4. I have a table pulling data from a database. Everything works getting the data to show in the table, however the content under the table isn't showing up. I'm using bootstrap 4.0 for layout, so I have rows and cols with the table being the third row and two other rows, not showing, under the 3rd row. I've moved one row about the table row and it show up, but put it back under the table and it disappears. I've ensured I have the right amount of div tags for each of the rows and cols. I'm at a loss
  5. Hi all, I have a php file to check a users input and it seems pretty straight-forward as far as logic goes, but the variable seems to be concatenating the "badEntry" onto its return value. I've been over it and over it and can't seem to see what's wrong. I originally had $userInput as the only return variable, but when I started having trouble I added the $toReturn variable to hopefully make it clear what I was doing wrong. Didn't help. I enter 'sakde12345' and I get that back with 'BadEntry' concatenated to it - looks like this - sakde12345BadEntry. My callback function is supposed
  6. BACKGROUND: Working with Matomo has compelled me to dig deeper into the way that information gets passed over the internet. Up until now I have assumed that I can pass just about anything in a query string. In fact, this is exactly what I have been doing. What I am beginning to realize is that the PHP $_POST and $_GET variables have been doing work of which I was not aware. I have come to this conclusion with my new encounter of the encodeURI(), encodeURIComponent(), decodeURI(), and decodeURIComponent() functions. Indeed, I have read that no information can be passed in an HTTPRequest
  7. Hi all, I have a couple of questions that popped up while studying php; really not questions, but I want to get some confirmation that my deductions are correct from what I've figured out. I was getting very confused over the differences in the object-oriented mysqli and the procedural mysqli and translating from one to the other. I think I like using OOps better The reference list on w3 only shows the procedural syntax so I wanted to make sure I was coming up with the correct OOps. Things like 'mysqli_query($conn,$sql)' becomes '$conn->query($sql)'. I could see that quite clearly in
  8. Hello I'm facing a problem I cant really solve. I want to place a backlink in the shape of either a textlink or an img banner outside my own server. (for instance inside an iframe) I want to be able to track download impressions and referrer clicks. Can this be done with php or not? It seems technically not possible to place php on someone else's server. What would you recommend?
  9. Hallo, Can anybody help for this question. I have changed my computer. And now my browser (google chrome) can not read php-files from my computer. I have installed PHP from XAMPP. What may be the reason for this?
  10. i want to build a bar chart with chartJS and database mysql with two different query, but bar chart not showing. can anyone help me to correct the code? this my query and javascript: <?php $a = mysqli_query("select count(a) as total1 from tbl"); $b = mysqli_query("select count(b) as total2 from tbl"); ?> <body> <div> <canvas id="chart"></canvas> </div> <script> var ctx = document.getElementById("chart"); var chartdata = { labels: 'CHART', datasets: [{ label: "A", dat

Hi everyone, I am trying to set up the flexible with array, like set up the array by count the columns in tables in the Database, so I am still figure how to create variable word through loop to allow equalized from $_post as if $_post appear in two or three or four...I figured out to set up the $_post in loop, but I haven't find a way to have create new variable to equalized with $_post in loop in same time. here my code <!doctype html> <html> <head> <title>Add name and number</title> <link href="defaultdatabase.css" rel="stylesheet" typ

    Hi, I am working on a simple login for just 1 person.. me .. to be able to update my blog online. I would like to have the login button on the blog page itself. I currently have it set up as a modal. I have the database setup for 4 columns - ID, date, title, content and signedby I have the form page set up as well (blog.php), and the database access dbconfig.php file is written also. 1. - wrote up the modal button so that when I click on the login/submit button it should call up pswchecking.php to verify that the username and password are me only, and that if it is true,

  14. I have a form written using HTML5 and CSS3, final validation is performed on submit with JavaScript. Then, the form will be sent to the server, most likely using PHP's mail() function. I don't recall how to include two items such as these in a form's action="...", I'd deeply appreciate if someone could refresh my memory! Thank you
  15. BACKGROUND: The following code was copied from the Grammar Captive mainpage where it performs just as it was designed to perform. Sadly, however, it fails on my local test server. The error log to which the file points indicates nothing and the data is properly entered into the data base. Further, although the PHPMailerAutoload.php class loads properly, the mail does not get sent and message is produced. Finally, the Javascript Console claims the following: "Failed to load resource: the server responded with a status of 500 (Internal Server Error)". And, the resource that it names is th
  16. Hello W3S - me again... So i have this little peace of code: if( isset($_POST['FORMNAME_submit_search']) ) { $qur = ""; @$SearchKeywords = mysqli_real_escape_string($dblink, $_POST['FORMNAME_SogProfilBar_Keywords']); // Search Bar Profil Keywords @$MinAlder = mysqli_real_escape_string($dblink, $_POST['FORMNAME_MinAlder']); // Minimum Alder @$MaxAlder = mysqli_real_escape_string($dblink, $_POST['FORMNAME_MaxAlder']); // Maximum Alder @$Landsdel = mysqli_real_escape_string($dblink, $_POST['FORMNAME_Landsdel']); // Landsdel
  17. BACKGROUND: I am now running with PHP 5.5.38, and things are nearly back to normal. My error messages have returned, and things that once worked, now function well again. This said, I wish to make good on the pain and disappointment that I suffered and am requesting your help to do so. REQUEST: Please find below a PHP class that I created in order to gather data from my database. It works fine in my current PHP environment and produces the expected results. It has been upgraded to handle multiple languages and editions of the same letter number. In addition, I have included a list
  18. It's been a long time since that PHP class in college, and the majority of my focus since graduating has been on HTML5 / CSS3 / JavaScript. I'm getting ready to go live with a new website. I have a contact form build with HTML5 and CSS3 with validation done with JavaScript. The only problem is, I'll need a PHP script to send the form via email. Is there a basic, easy to use script that someone could recommend? Also, is it possible that my web host (I'll possibly be going with Go Daddy) will make such a script available? I'm hoping to find something that's essentially plug and play.
  19. Hello W3S! So i have some problems again, hoping you can help me clear it out. I am currently trying to make a search page where a user can search for profiles with different profiles information such as tattoos, height, etc. And i have some difficulties making it work, hoping you can spot some sort of errors that i cannot. Please note that it's been a while since i've been making a fully working searcher with php and sql, so sorry for the messed up code, if so hehe Okay. So i have 6 files, follows as such: 1. index.php (being the main file) - (LOCATION: ROOT/FILE_HERE.php)
  20. Suggestion 1: I had an idea for w3school for a very long time and this idea will help people learn better and even make school suggest it more. Add in a tutorial where people will have to figure how how to fix codes like it's almost like the try-it-out but you have to go through courses and learn programming through that, almost like khan academy almost except with programming except khan academy only teaches html and not PHP. And also it wouldn't hurt to show videos of how to understand PHP more. And also how to create websites like facebook and youtube and have interactive videos as well l
  21. I'm learning php & sql. I can do the programming and logic, but how to put it all together is where I get confused. I have copied, from the w3 tutorial, the php form validation complete, and it worked fine. I have also used the php/sql database tutorial to copy the 'insert into' code and it works fine with a Db I set up on the local host. Now I would like to save the info in the form to a database table, but I'm not sure where to insert the code to connect to the database. I tried just adding the code at the bottom of the 'Form Complete' code but it didn't seem to take - no error co
  22. Hallo everyone. Thanks for a great website. I have been trying for a few days to get a safe, working php form that saves input to mysql. I have looked at several examples from different websites. The problem is that the form values are being stored to the database before the form validation process is complete. I have tried wrapping the process.php code in a function and only calling the function after the validation code is done and implemented some checks in a desperate attempt to resolve the matter using some global variables and a function that checks if the validation
  23. Hi I have a question, but no real example yet. I wonder if someone can tell how to create a serial number that counts from 10000 to 100000 en divide it as a unique id over several databases and table.columns? I dont want to have an example with uniqid() , but counting up with one. I have no clue how to do this can someone please give any suggestion?
  24. I made a website using HTML and some javascript. I tried to make a contact form with PHP, but something goes wrong when submitting and I don't understand why. I followed a tutorial and can't see any mistakes (first time using PHP, so there might be a lot I can't see). Here is the HTML-code and PHP-file. I also uploaded the original, in case you prefer to open it that way.. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"><head> <link rel="styl
  25. Hi. I have a doubt with the proper way of sanitize the forms with php. In the php form validation lesson https://www.w3schools.com/php/php_form_validation.asp is used a function for this purpose: function test_input($data) { $data = trim($data); $data = stripslashes($data); $data = htmlspecialchars($data); return $data; } But in the filters lesson, https://www.w3schools.com/php/php_filter.asp I understand that filters can do the same task. Is this correct? Are two approaches valid? Which one should be used nowadays? Thanks in advance!
