I'm making a plugin with a class and methods.

This class gets called through the theme ( hard coded ) to enqueue and localize my js. it also prepares it for ajax. However, i keep getting ERROR: 400

POST http://www.devsite.local/wp-admin/admin-ajax.php 400 (Bad Request)

I've ran ajax outside of a class in multiple plugins and at the functions.php with no issues, but i can't get it to work inside a class.

This is my code:

class CCYTFeatured {
public function __construct(){
        $this->cc_yt_scripts();
        add_action( 'wp_enqueue_scripts', array($this, 'cc_yt_scripts' ));

        add_action( 'wp_ajax_cc_yt_featured', array( $this, 'cc_yt_featured' ) );
        add_action( 'wp_ajax_nopriv_cc_yt_featured', array( $this, 'cc_yt_featured' ) );

}
// Load CSS AND JAVA FRONT END
public function cc_yt_scripts() {
    wp_register_style( 'cc_yt_style',
        plugins_url( '/css/cc_yt.css', __FILE__ ),
        array(),
        cc_yt_version()
        );
    wp_enqueue_style('cc_yt_style');

    // JAVASCRIPT
    wp_register_script( 'cc_yt_javascript',
        plugins_url( '/js/cc_yt.js', __FILE__ ),
        array('jquery'),
        cc_yt_version(),
        true
    );
    wp_enqueue_script('cc_yt_javascript');
    wp_localize_script(
        'cc_yt_javascript',
        'cc_yt_script',
        array(
            'ajaxurl'   => admin_url( 'admin-ajax.php' , __FILE__ ),
            'ajax_nonce' => wp_create_nonce('my_nonce'),
        )
    );
}
public function cc_yt_featured(){

    check_ajax_referer( 'my_nonce', 'security' );
    echo json_encode('IM HERE, YOU CAN FIND US');
}
}

This is my JavaScript ajax call:

jQuery.ajax({
    url: cc_yt_script.ajaxurl,
    type : 'POST',
    data: {
        action : 'cc_yt_featured',
        security: cc_yt_script.ajax_nonce,
        post: 'bananas',
    },
    success: function(response) {
        console.log('THIS IS THE RESPONSE:  '+ response);
    }
});

I keep getting the same error, i can't figure out what is wrong with my class:

This is how i call it.

$cc_yt = new CCYTFeatured;

I have that call hard coded inside a theme file. This does enqueue the styles and scripts successfully.

The ajax get is the following:

http://www.devsite.local/wp-admin/admin-ajax.php?action=cc_yt_featured&security=79e39910b8&post=bananas

Anyone have any clue what i'm doing wrong??

Thanks!

  • Note that i tested it out side the classs ( copied the enquee and localizing out of the class and ran it) It work perfectly.. I think i might have an error on the way i have my class structured. I still need to be able to run the ajax call successfully from the class. Nov 12, 2018 at 23:20
  • What happens if you place $cc_yt = new CCYTFeatured; in your functions.php file? Nov 12, 2018 at 23:29
  • Have you considered using the more modern REST API instead? It's easier to debug, WP Admin AJAX isn't so forgiving with mistakes

  • Additionally, when you say "I have that call hard coded inside a theme file." which theme file are you referring to?

  • If $cc_yt = new CCYTFeatured; is inside a template, then it's not going to be run during an AJAX request, which means your callbacks won't be hooked, leading to a 400 error. Nov 13, 2018 at 0:19

All the code is correct except the way i was calling.

I created a different method for __construct and then called it on the plugin it self so the scripts and styles get hooked before the templates. In my template i called the class again and the methods i need it. I no longer constructed my method all at once.
