Passing a PHP variable using ajax - php

Question

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.

Answer 1

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>

Answer 2

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'];
}
?>

Answer 3

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.

Answer 4

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>>

Answer 5

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'];
}
?>

Answer 6

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'];
}
?>
