I just made a plugin with some meta data and such. I need to alter the content when, but my add_filter('the_content') doesn't do anything...

Code:

public function run() { 
    add_action( 'admin_enqueue_scripts', array( $this, 'enqueue_scripts' ) );
    add_action( 'admin_enqueue_scripts', array( $this, 'enqueue_styles' ) );
    add_action( 'add_meta_boxes', array( $this, 'add_meta_box' ) );

    add_action( 'save_post', array( $this, 'save_post' ) );
    // HERE IS MY PROBLEM:
    add_filter( 'the_content', array( $this, 'some_content_method' ) );

}


public function some_content_method( $content ) {

    var_dump('Why u no?');
    $content .= 'Why u no work?';
    return $content;
}

If I write 'add_meta_boxes' the dump will work.

    // HERE IS MY PROBLEM:
    add_filter( 'add_meta_boxes', array( $this, 'some_content_method' ) );

If I change it to add_action instead of add_filter nothing happens either

    // HERE IS MY PROBLEM:
    add_action( 'the_content', array( $this, 'some_content_method' ) );

everything else works - can anybody help?

  • How does run() get executed?

  • It's in a admin/class.php un by the main plugin php file: function run_acme_plugin() { $plugin = new Acme_Plugin(); $plugin->run(); } run_acme_plugin(); And that works just fine, because it works when I substitute the content for add_meta_boxes. everything works just fine, just not the 'the_content'

  • OK, just making sure it wasn't only added on admin requests. So just to clarify, you're using the_content() function on a front end request and not seeing the filtered content there?

  • I am using: add_filter( 'the_content', array( $this, 'some_content_method' ) ); and I've create some_content_method() in which I var_dump() something - and nothing happens.... If I call: add_filter( 'add_meta_boxes', array( $this, 'some_content_method' ) ); instead, my var_dump is shown I don't understand why.

    My question is where you are expecting to see this filtered content. It's not typically used anywhere on admin screens, it's a front end function/filter for templates. It seems like you're doing admin screen stuff.

With help from Milo I realised that 'the_content' wasn't meant for the admin part of WP, which is why I didn't see my var_dump as I expected.

Conclusion: A rookie mistake!
