Passing a PHP variable using ajax


I'm trying to pass a php variable from page1.html (which contains a php variable that I got from another form) to page2.php using ajax but it's not working, so I need your help.

code from page1.php:

<script>
var url = 'page2.php';
$("#save").click( function() {
    $.ajax({
        url : url,
        type: 'post',
        data : {
            admin : <?php echo $admin; ?>,
            gname : <?php echo $gname; ?>,
            filename : docname,
            content : encodeURIComponent(editor.getValue())
        }
    });
});
</script>

The datas filename and content are being sent successfully but admin and gname are not.

Thanks in advance.

UPDATE:

<?php
    if(isset($_GET['admin'])) {
    $admin = $_GET['admin'];
    }
    if(isset($_GET['gname'])) {
    $gname = $_GET['gname'];
    }
?>

This code is where I get the php variable that I want to send, from another form which is irrelevant to this question.

You are sending POST parameters,while using get in PHP script. And another issue is you are not using quotes with $admin and $gname variables in ajax request.
Try following : 

<script>
var url = 'page2.php';
$("#save").click( function() {
    $.ajax({
        url : url,
        type: 'post',
        data : {
            admin : '<?php echo $admin; ?>',
            gname : '<?php echo $gname; ?>',
            filename : docname,
            content : encodeURIComponent(editor.getValue())

        }
    });
});
</script>

PHP Script:

<?php
    if(isset($_POST['admin'])) {
        $admin = $_POST['admin'];
    }
    if(isset($_POST['gname'])) {
        $gname = $_POST['gname'];
    }
?>

Check if it helps you.

Here you go buddy, replace your script code with this.

<script>
var url = 'page2.php';
var admin = '<?php echo $admin; ?>';
var gname = '<?php echo $gname; ?>';
$("#save").click( function() {
    $.ajax({
        url : url,
        type: 'post',
        data : {
            admin : admin,
            gname : gname,
            filename : docname,
            content : encodeURIComponent(editor.getValue())
        }
    });
});
</script>

Your below code 

<?php
    if(isset($_GET['admin'])) {
    $admin = $_GET['admin'];
    }
    if(isset($_GET['gname'])) {
    $gname = $_GET['gname'];
    }
?>

is to be replaced by

    <?php
    if(isset($_POST['admin'])) {
    $admin = $_POST['admin'];
    }
    if(isset($_POST['gname'])) {
    $gname = $_POST['gname'];
    }
?>

As everyone is saying you're mixing POST and GET. But it caught another thing that may bother you. Are those variables strings? If they are, maybe you're missing the apostrophe/single quote.

<script>
var url = 'page2.php';
$("#save").click( function() {
$.ajax({
   url : url,
    type: 'post',
    data : {
        admin : '<?php echo $admin; ?>',
        gname : '<?php echo $gname; ?>',
        filename : docname,
        content : encodeURIComponent(editor.getValue())
    }
});
});
</script>>

Youre using the type post so must use the $_POST in php

PHP

<?php
    if(isset($_POST['admin'])) {
    $admin = $_POST['admin'];
    }
    if(isset($_POST['gname'])) {
    $gname = $_POST['gname'];
    }
?>

You are using $_GET['admin'] which is used to fetch parameters delivered with GET method. You should be using $_POST['admin'] since you have set POST as your http request type in the JS code.
