Override saved_venues_dropdown()

[gonzalosanza]

I need to change the behaviour of saved_venues_dropdown() which is in the-events-calendar/lib/the-events-calendar.class.php

I know that I can override views by placing a new version in my theme’s tribe-events folder, but can I do this with the aforementioned file? If so, I must not have the folder structure right. Any hook or similar?

(the reason because i want to override it, is because I have created a custom field for venues and organizers, which allows admins, to decide if those venues or organizers are displayed on dropdowns, that custom field is working, but now I need to modify saved_venues_dropdown and saved_organizers_dropdown to make this feature work properly)

Any advice?
Thanks.
Gonzalo.

Hi Gonzalo,

Overridding the template (modules/venue.php in this case) is still a good way to go since if you write a replacement function you can drop it in there, replacing the call to tribe_community_events_venue_select_menu().

Alternatively, you could unhook TribeEvents::displayEventVenueDropdown() — currently it runs when the tribe_venue_table_top action fires — and hook up your alternative function.

It is a slightly more advanced customization and if you have any doubts I’d recommend following the first strategy and overriding the modules/venue.php template.

Does that help?

Hi Barry, and thanks!
I have tried with this code

add_action( ‘wp_loaded’, ‘replace_displayEventVenueDropdown’ );

function replace_displayEventVenueDropdown() {
if ( is_admin() ) return;
$events = TribeEvents::instance();
remove_action( ‘tribe_venue_table_top’, array( $events, ‘displayEventVenueDropdown’ ) );
add_action( ‘tribe_venue_table_top’, array( $events,’displayEventVenueDropdown_custom’) );
}

function displayEventVenueDropdown_custom( $postId ) { …my custom code… }

But Im getting this error:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘TribeEvents’ does not have a method ‘displayEventVenueDropdown_custom’ in /home/mydomain/public_html/wp-includes/plugin.php on line 496

I tried smalls modifications on this, but nothing…

Any help? Thanks anyway!

Hi Gonzalo!

add_action( 'tribe_venue_table_top', array( $events, 'displayEventVenueDropdown_custom' ) );

The above is telling PHP to look in the wrong place – your custom replacement is not a part of the main event class, it’s a standalone function 🙂

Try changing that to just:

add_action( 'tribe_venue_table_top', 'displayEventVenueDropdown_custom' );

Does that help?

Many thanks barry, but still not working, now im getting this error:

Fatal error: Using $this when not in object context in /home/segoviaencendida/public_html/wp-content/themes/eventica-wp-child/functions.php on line 461

line 461 contains:
<td style=”width:170px”><?php printf( __(‘Use Saved %s:’, ‘tribe-events-calendar’), $this->singular_venue_label ); ?></td>

and 462 contains:
<td><?php $this->saved_venues_dropdown_custom( $VenueID ); ?></td>

Hi Gonzalo,

If you define a standalone function – ie, it doesn’t belong to a class and will never exist within an instantiated object – then you cannot use the keyword $this.

Instead, if you need to refer to members of the main TribeEvents object from your function, please use TribeEvents::instance() in place of $this.

I hope that helps – however because we’re now very much in custom development territory we’ll be unable to help further and so I am now going to close this topic.

Good luck, though, it definitely looks like you are quickly closing in on a nice solution 🙂
