Question

I have a php file (myxml.php) that uses a 3rd-party API to return XML. It echoes the XML on the last line.

 $xml = file_get_contents($url);
 echo $xml;

Another php file (index.php) uses jQuery to read this XML in:

$(document).ready(function(){
        $.ajax({
            type: "GET",
            url: "myxml.php",
            dataType: "xml",
            success: function(xml) {

My index.php file needs to pass the myxml.php file a variable called ‘searchitem’ that it can use before calling the API.

How do I pass $searchitem to myxml.php ?

Also, for better performance, can I import the php variable $xml to my ajax code above without the need to echo it?

Thanks in advance

Answer 1

You apparently are using jQuery.

Just add it to the url (so build the jQuery syntax with php)

    $.ajax({
        type: "GET",
        url: "myxml.php?searchitem=<?php echo $searchitem; ?>",
        dataType: "xml",
        success: function(xml) {

In turn, on myxml.php you can get this with the $_GET variable.

$searchitem = $_GET['searchitem'];

Without echo? Only possible if you don’t need ajax, so you can just include the myxml.php file into the index.php file. But I assume there is a good reason for doing ajax
