Need Help for integrating ACF in custom plugin

  • Hello,

    since round about 12 months we are developing a plugin which uses ACF for generating the needed fields. All is working actually but now i decided to make the plugin “more object-orientated”…. The result is now that “adding normal taxonomy terms by hand” is not normal…the term is added but the page (the AJAX part) blocks and stays there. Only by reloading the page the term is present.

    I tried to find the error and its based on the ACF integration. Not ACF itself only my way of integration.

    I found a sample to integrate ACF within a helper class and do the complete integration in this class. I think that there is my error.

    In the documentation are only a few lines for that but i need a little bit more…..

    In my plugin (by using the object-orientated boilerplate way with the possibility to access all classes from every class) i added my helper class and there i did the init of ACF but i think that there is the error.

    Where i could find a sample for that?

    What i want?

    – in the final plugin ACF should be integrated
    – the complete ACF definitions/fields/filters and so on should be reside in a class
    – the class is initiated by the normal init procedure in the main plugin file (class-plugin-name.php) and there exist the part 

    private function define_admin_hooks() {
$this->acf		= new Picture_Frame_ACF( $this->get_plugin_name(), $this->get_plugin_prefix(), $this->get_version(), $this->main );
}

  • This is my main plugin class:

  • It was my fault !!!!!: By defining acf/save_post and NOT differentiating the ‘pages’ the WordPres AJAX goes into ‘the neverending search’. Now i switched to filter by pages/posttypes/categories and it works perfect.
