Send data to a php function using .ajax

I know that to send data to a php file using $.ajax is something like this:

$.ajax({
type: "POST",
url: "some.php",
data: { name: "John", location: "Boston" }
}).done(function( msg ) {
alert( "Data Saved: " + msg );
});

What I'd like to know is if it is possible to send the data on a specific function inside that file. If it is, can you show me how? Thank you.

you can do it by following code. add one more parameter to your ajax call, like file_name=your_function_name, for instance here i send the ajax request as your data with function_name=getResult, it will call the getResult function in php file.

$.ajax({
type: "POST",
url: "some.php",
data: { name: "John", location: "Boston",  function_name: "getResult"}
}).done(function( msg ) {
alert( "Data Saved: " + msg );
});

<?php
$function_name = $_POST['function_name']
switch($function_name){
    case $function_name:
        getResult();
        break;
    case $function_name:
        updateFunction();
        break
}
?>

switch statement is optimized way when you are having more cases.

Yes, for that you have to check which function you have to call. Also there is no need to pass the POST parameters inside function because $_POST is superglobal array you can access them inside function without passing via parameter.

type: "POST",
url: "some.php",
data: { name: "John", location: "Boston", func : 'add' }

In some.php

if(isset($_POST['func']) && $_POST['func'] == 'add') {
   // call function here and pass parameter
   func_add();
}

add an action paramater to your ajax :

$.ajax({
type: "POST",
url: "some.php",
data: { name: "John", location: "Boston", action: "action1" }
}).done(function( msg ) {
alert( "Data Saved: " + msg );
});

and in your php file :

<?php
if($_POST['action'] == action1) {
  action1(); //Do the function named "action1"
}
?>

You don't, but you could add a query string to the url: someurl.php?function=MyFunction and use $_GET['function'] to find out which function should handle the request.

Create your some.php PHP file like this:

<?php

foo($_POST);
function foo($postData) {
  // Process the data
  var_dump($postData);
}

The above code will immediately pass the data that is posted to the given function 'foo'.
