Not used Javascript -> Ajax -> PHP -> Javascript before and I am struggling to pick-up the return value. Ajax is calling the PHP, but all I am getting back is the HTML for the web page. Can anyone see what I am doing wrong?
Javascript: -
onChange: function(value, text, $selectedItem) {
jQuery.ajax({ url : 'index.php', type : 'post', data : { action: 'getTest', param : text },
success: function(result){
console.log('Sucess',result);
},
failure: function(result){ console.log('Failed'); }
});
}
PHP: -
$_action = isset($_Post['action']) ? $_Post['action'] : '0';
if ($_action == 'getTest') {
$test = $_Post['param'];
echo $test;
exit;
}
As I said, RESULT just seems to contain the page's HTML and not the expected string value.
Thanks
Your post variable is with small caps letters. However the Variable should be full caps ($_POST). So your php is not going into the if statement.

To debug these kind of issues start logging variables like $_action and check if their value is what you expect it to be. Then check if the if statement actually fires, etc. until you find the error.
