i have this school assignment and i really want to make a forum page but i dont know how to make it functional. pls help me.

i rephrase yours answer as look at the pagination code there is 3 pages and 2 pages and 10 pages total means when no search condition is given it created 10 pages but problem is when ist condition is true and in result bottom of 3 pages is created and when i click one of my page data is refresh but in bottom pagination is gone to 10 while it should restrict to similarity when 2nd condition is true 2 pages is created and when i click one of two pages , data is refresh correctly but but in bottom the pagination is gone to 10......my question is how i can restrict the pagination along with the data if(!empty($searchData) || !empty($searchName)) case "search_data":{ //code here //code for pagination for example 3 pages is created in this condition } break; case "search_name": { //code here //code for pagination for example 2 pages is created in this condition } break; } else { //code here //code for pagination for example 10 pages is created in this condition } } <form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>"> <button type="submit value="search_data">Search Data</button> <button type="submit value="search_name">Search Name</button> </form>

I'm attempting to pass a text string from a javascript process to a php process, using XMLHttprequest, and am getting an 'undefined array key' error. The php process should save the string to a file. It appears to pass the string to the php code okay as it returns the message 'File saved', but it also gives the error message 'undefined array key' on 'data' on line 2 of the php code. I appears to be saving a blank string to the text file as it overwrites any previous saved text in the file. So it looks like no data is being passed to the php codebut it is still try to save it. I'm no sure whether the problem is on the javascript side or the php side. The attached files are test code which reproduces the error. Clicking on the button in 'TestProgram.php will attempt to pass the test string to 'saveGame.php which should save the text string to 'test26.txt :- Any help would be much appreciated. TestProgram.php saveGame.php test26.txt

Hello, please could you help me with my problem about PHP script? I need my program to detect user browser because html function 'type=''date'' ' is not supported by SAFARI and IE.

Hi All, I've seen that in PHP you can include a require or include function which saves you from having to add the entire code for headers and footers for each page. Does a similar things exist in HTML? If so, please direct me. Thanks in advance Russell

I have used the W3 template to produce a script that uploads image changes to a directory on my server, updates the URL in my database and logs the event. Works beautifully IF the source folder is: \Pictures or \Pictures\Personal But fails if it is any other source folder, even the peer folder \Pictures\BarImages Why?

In the lesson on PHP Filters in the code sample "Validate an Integer" there is the following code: <?php $int = 100; if (!filter_var($int, FILTER_VALIDATE_INT) === false) { echo("Integer is valid"); } else { echo("Integer is not valid"); } ?> Why use this expression: (!filter_var($int, FILTER_VALIDATE_INT) === false) instead of what seems to me to be the more logical expression?: (filter_var($int, FILTER_VALIDATE_INT) === true) Thanks.

https://www.w3schools.com/php/phptryit.asp?filename=tryphp_filter_adv3 is a tutorial example. It attempts to validate what appears to be a valid URL but claims it is not. I see this forum gets little use, so has the language changed since the example was created, is there a mistake in the example, or is the problem on my end in the browser? I am using the latest FireFox browser under Windows 10.

In PHP 5, I conventionally opened my pages with <?php but within the pages I often used <? to open a php block, e.g., <?echo $variable; ?>. In PHP 7, I find it is necessary to always use <?php and follow it with a space, e.g., <?php echo $variable; ?> I haven't been able to find any reference to this syntax change so my question: Is this a new requirement of PHP 7? Can it be turned off? Otherwise, I will need to edit all of the sites where my earlier habit was used, which I think I can do but would feel compelled to spend some hours testing afterward.

At Ingolme's suggestion, I've switched from simpleXML to DOMXML for this because I need to be able to replace a node. I've done my best to follow PHP.com examples, and everything seems to work up until the point of the actual replacement. I hope you can spot what's keeping it from working. The vars found in the heredoc are assigned earlier from the customer input form. if $found is positive, it contains a cId (customer ID) that exists in the DB and should be updated with any new info (code shown). If negative, it's abs() is the cId for a new node to be added (code omitted here). In $xml, the <customer> node is child of <customers>, which is child of <root>. If I comment out the replaceChild line before the break, execution continues unhindered. Nodename reports "customer" and nodetype reports 'XML_ELEMENT_NODE' for both $node and $oldNode, so I don't know what is preventing the replacement. // SAVE CUSTOMER DATA // $found= $cId; $cId = abs($found); // Create DOM from data file $xml = new DOMDocument; $xml->formatOutput = true; $xml->load("Titles data.xml"); // Create node from customer input $str = <<<XX <customer> <cId>$cId</cId> <organization>$organization</organization> <website>$URL</website> <contact>$name</contact> <email>$email</email> <phone>$phone</phone> <addr>$address</addr> <city>$city</city> <state>$state</state> <zip>$zip</zip> <orders> <oId></oId> </orders> </customer> XX; $DOMChild = new DOMDocument; $DOMChild->loadXML($str); //turn $str into DOMDoc $node = $DOMChild->documentElement; //not sure if this is right, example suggests it is $node = $xml->importNode($node, true); //Is this necessary? examples suggest it is if ($found > 0) { //if positive, $found contains cId of desired customer $list = $xml->getElementsByTagName("cId"); //list of ID's to search for ($r = $list->length -1; $r > 0; $r--) { //find customer that fits cId if ($list->item($r)->nodeValue==$cId) { //when found, $r is index to customer node list $oldnode=$xml->getElementsByTagName("customer")->item($r);// get node to be replaced $msg=$r."—"; //$msg is included in email sent later; shows arrival here $node->replaceChild($node, $oldNode); //THIS LINE FAILS, HALTING EXECUTION break; } } }
