How to call a php function from ajax?
You cannot call a PHP function directly from an AJAX request, but you can do this instead:
<? php
function test($data){
return $data+1;
}
if (isset($_POST['callFunc1'])) {
echo test($_POST['callFunc1']);
}
?>
<script>
$.ajax({
url: 'myFunctions.php',
type: 'post',
data: { "callFunc1": "1"},
success: function(response) { console.log(response); }
});
</script>
As a structure for this kind of purposes, I suggest this:
PHP
<?php
if(isset($_POST['action'])){
if ($_POST['action'] == "function1") { func1(); }
if ($_POST['action'] == "function2") { func2(); }
if ($_POST['action'] == "function3") { func3(); }
if ($_POST['action'] == "function4") { func4(); }
}
function func1(){
//Do something here
echo 'test';
}
?>
jQuery
var data = { action: 'function1' };
$.post(ajaxUrl, data, function(response) {
if(response != "") {
$('#SomeElement').html(response);
}else{
alert('Error, Please try again.');
}
});
As mentioned, you can't call a PHP function directly from an AJAX call.
For AJAX request
Include jQuery Library in your web page. For e.g.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
Call a function on button click
<button type="button" onclick="create()">Click Me</button>
While click on button, call create function in JavaScript.
<script> function create () { $.ajax({ url:"test.php", //the page containing php script type: "post", //request type, dataType: 'json', data: {registration: "success", name: "xyz", email: "[email protected]"}, success:function(result){ console.log(result.abc); } }); } </script>
On the server side test.php file, the action POST parameter should be read and the corresponding value and do the action in PHP and return in JSON format e.g.
$registration = $_POST['registration'];
$name= $_POST['name'];
$email= $_POST['email'];
if ($registration == "success"){
// some action goes here under php
echo json_encode(array("abc"=>'successfuly registered'));
}
