如何使用jQuery ajax调用PHP函数? [英] How to call PHP function using jQuery ajax?

问题描述

我有一个名为myfunctions.php的文件，其中有很多功能，例如

I have a file called myfunctions.php where I have a lot of functions, like

function sendForm(){
    //save form
}
function fn2(){
 //do something
}
 // Other functions ...

和jquery代码，

$.ajax({
    url: "myfunctions.php",
    type: "POST",
    contentType: "application/x-www-form-urlencoded",
    data: {key1: "value1", key2: "value2", key3: "value3"},
    complete: function(){
        //completado
        alert("complete");
    }
});

我需要在此文件中调用特定的函数；例如sendForm().我该怎么办?

I need call specific function in this file; for example sendForm(). How can I do that?

推荐答案

在PHP中

<?php
// create a list of approved function calls
$approved_functions = array('sendForm','fn2');

// check the $_GET['function'] and see if it matches an approved function
if(in_array($_GET['function'], $approved_functions))
{
    // call the approved function
    $_GET['function']();
}

function sendForm(){
    //save form
}
function fn2(){
 //do something
}

在AJAX中

// specify which function to call
url: "myfunctions.php?function=sendForm",
