WP functions undefined in plugin-CodePudding

I am having trouble with a plugin I am writing, the plugin shows a form and the form submits to ajaxupload.php.

Basically in my plugin file:



add_action('plugins_loaded','add_to_menu');

function add_to_menu(){
    add_action('admin_menu', 'test_plugin_setup_menu');
}
 
function test_plugin_setup_menu(){
    add_menu_page( 'Test Plugin Page', 'add new entry', 'manage_options', 'test-plugin-link', 'test_init' );
    // ,'dashicons-database-add'
}
 
function test_init(){
    //echo "<h1>Hello World!</h1>";
    // do_action( 'admin_init' );

    include(ABSPATH."/wp-content/plugins/my-plugin/form.php");
    
    
}

In form.php I can call wp functions!

    <?php 
    // this works!
    echo wp_get_current_user()->user_login;
    ?>
    
    <form>
    ...
    </form>
    <script>
    $(document).ready(function(){
        $("#my_form").on("submit",function(e){
        e.preventDefault();
        var sendData = $( this ).serialize();
                $.ajax({
                    url: "../wp-content/plugins/my-plugin/ajaxupload.php",
                    type: "POST",
                    data:  new FormData(this),
        ...
       </script>

in Ajaxupload.php I can't use any WP constants or functions before submission...



if( !empty($_POST['imgurl']) || !empty($_FILES['image']) )
{
$someform_field = $_POST["name"];
echo wp_get_current_user()->user_login; //this line fails

//then call to wpdb to add data to DB

What should be the correct sequence to make wp functions usable in the ajaxupload.php file?

CodePudding user response：

You have to load the wp-load.php file in your ajaxload.php, which loads all wordpress functions, because your ajaxload.php file is called directly:

<?php 
require_once __DIR__ . '/../../../wp-load.php';

$someform_field = $_POST["name"];
$user = wp_get_current_user()->user_login; // should now work

//then call to wpdb to add data to DB
