Here is how you can add another button to the admin page.
Download the MetaBox plugin
Create a file called “button.php” in the wp-content folder
Inlcude “button.php” in functions.php
In button.php, type:
add_filter( 'rwmb_meta_boxes', 'admin_button_register_meta_boxes' ); function your_prefix_register_meta_boxes( $meta_boxes ) { $prefix = 'admin_button_'; $meta_boxes[] = array( 'id' => 'standard', 'title' => esc_html__( 'Standard Fields', 'admin_button' ), 'post_types' => array( 'post', 'page' ), 'context' => 'side', 'priority' => 'high', 'autosave' => true, // List of meta fields 'fields' => array( array( 'id' => 'custom_html', // Field name: usually not used // 'name' => __( 'Custom HTML', 'admin_button' ), 'type' => 'custom_html', // HTML content 'std' => ' ', ), ), ); return $meta_boxes; }
Now you have a form controlled by the button. Depending on what you want to do with the button, you can have a PHP method check to see if the form was posted or you can have the button trigger a javascript event.
Hope that helps!
