我在前端表单的插件中使用ajax。但只有当我把add_action("wp_ajax_..." 在插件加载程序中。我想在另一个文件中注册呼叫。

我尝试过：

function my_plugin_init() {

    if ( ! is_admin() ) {

        require( dirname( __FILE__ ) . \'/inc/my-plugin-functions.php\' );

    }

}
//add_action( \'wp_loaded\', \'my_plugin_init\' );
add_action( \'init\', \'my_plugin_init\' );

但两者都不是add_action 钩子似乎起作用了。Ajax失败，因为它在中找不到Ajax函数inc/my-plugin-functions.php.

如果我将ajax功能放在插件加载器中，一切都会正常工作：

function my_plugin_etc() {

    $title = sanitize_text_field( $_POST[\'title\'] );

    $meta = update_post_meta(1234, \'test_key\', $title);

    if ( $meta != false ) 
        echo json_encode(array(\'status\' => \'success\', \'message\' => \'Title added as postmeta.\') );
    else 
        echo json_encode(array(\'status\' => \'error\', \'message\' => \'There was a problem.\' ) );

    wp_die();    

}
add_action("wp_ajax_my_plugin_etc", "my_plugin_etc");

我不想把ajax函数放在插件加载器中。

为了注册文件中的ajax函数，应该使用什么样的钩子来包含文件？

add_action (\'wp_ajax_nopriv_my_plugin_etc\', \'my_plugin_etc\') ;

function my_plugin_init() {

    if ( ! is_admin() || wp_doing_ajax ()) {

        require( dirname( __FILE__ ) . \'/inc/my-plugin-functions.php\' );

    }

}
add_action( \'init\', \'my_plugin_init\' );

function my_plugin_init() {

    if ( ! is_admin() || (defined( \'DOING_AJAX\' ) && DOING_AJAX)) {

        require( dirname( __FILE__ ) . \'/inc/my-plugin-functions.php\' );

    }

}
add_action( \'init\', \'my_plugin_init\' );

// your javascript with ajax calls must be enqueued before wp_localize_script.     
wp_enqueue_script( \'ajax-script\', plugins_url( \'file_location.js\', __FILE__ ), array(\'jquery\') );
            // Wordpress localize script
            wp_localize_script( \'ajax-script\', \'ajax_object\', array( \'ajax_url\' => admin_url( \'admin-ajax.php\' ), \'we_value\' => 1234 ) );
