如何调用将调用我的插件功能的ajax函数

Question

I have the following function in my plugin

function IsIdInProject($id=null){
    if ($id=="test")
    {
      return true;
    }
     return false;
    }

I need to call this function from my page using jquery, but I do not understand what to put in my url parameter.

This code is located in settings.php page of my plugin (plugins/myplugin/settings.php)

I cannot just call url: mywebsite.com/plugins/myplugins/settings.php , right?

Answer 1

try to use action wp_ajax

Demo

add_action( 'wp_ajax_my_action', 'my_action_callback' );
function my_action_callback() {
$var ="no var";
$id=$_REQUEST['id'];
 if ($id=="test")
{
 $var=$id;
}
echo $var;

    wp_die(); // this is required 
}
