Call php functions using ajax

[alicefreak]

Hello guys

is it possible to create a single php file to contain all the functions to be called via AJAX and  get AJAX to call the specific function required rather than having to create individual pages for each AJAX request you need to make?

 

Many Thanks

Yes, just use a flag variable to indicate what to do, for example -- using jQuery's $.post

$.post("phpfile.php",{flag: 1, var: 'test1'}, function(data) {
   if(data.ret != 'ok') {
      alert('Error: ' + data.error_msg);
   } else {
      alert('Success');
   }
},"json");
$.post("phpfile.php",{flag: 2, var: 'test2'}, function(data) {
   if(data.ret != 'ok') {
      alert('Error: ' + data.error_msg);
   } else {
      alert('Success');
   }
},"json");

in your PHP file:

<?php
if (isset($_POST['flag'])) {
   switch ($_POST['flag']) {
      case '1':
         if (isset($_POST['var']) && $_POST['var'] != 'test1') {
            exit(json_encode(array('ret'=>'not ok','error_msg'=>'Input not correct')));
         }
//
//     do case 1 work
//
         exit(json_encode(array('ret'=>'ok')));
         break;
      case '2':
         if (!isset($_POST['var'])) {
            exit(json_encode(array('ret'=>'not ok','error_msg'=>'Input not found')));
         }
//
// do case 2 work
//
         exit(json_encode(array('ret'=>'ok')));
         break;
      default:
         exit(json_encode(array('ret'=>'no ok','error_msg'=>'Invalid flag')));
      }
   }
?>
