Adding action hook on front-end form submission

did you mean the event saving hooks/filters ?

Hooks, Actions and Filters on https://codex.www.ads-software.com/Plugin_API

if that’s what u talking about then YES.

yes, however can I know which specific hooks you’ve wanted?

Thanks for the response angelo!

I’m not very comfortable with PHP but I think this should work.

I want to overwrite event_statue to “0” on em_events table(on database) when the Front-end event form submitted.
I believe I can do this on my Theme’s functions.php file by adding the hook in there(below code; if it make sense).
Can u tell me what hook that will be? if that exist.

function update_event_statue($event_id){
$thisposteventid = $EM_Event->event_id;
    global $wpdb;
    $wpdb->update( $wpdb->prefix . 'em_events',
		array( 'event_status' => '0' ),
		array( 'event_id' => $thisposteventid )
		);
add_action( 'EVENTS_MANAGER_HOOK', "update_event_statue" );

If you take a look inside /events-manager/classes/ you’ll see the filters and hooks listed within the files. The one you need here is save_post.

Thank you calimin! I know I’m asking too much but my code is not working as I intended. could u plz help?
is it even possible to overwrite event_status like the way I was trying below? It does insert 0 in to event_status in DB but it created new event_id right before actual event’s event_id(that contains all the data from front-end form).

function update_event_status($event_id){
    global $wpdb;
    $wpdb->replace( $wpdb->prefix . 'em_events',
		array( 'event_status' => '0' )
		);
}
add_action( 'save_post', 'update_event_status' );

here’s another thread which may help you with this – https://wp-events-plugin.com/tutorials/saving-custom-event-information/

I have spent days to figure this out but I no luck so far. So I have to delete any old saves and insert new values?

seems to me ‘save_post’ hook executes before the front-end form executes which means it’s gonna be overwritten by whatever values from front-end form.
