Hi, is there a way to call a list of all event categories? I want to automatically call all event categories and then assign a custom URL to them (ie /events/?cat=catname) that will automatically load a page of all applicable events (I have that bit covered).
Any ideas on how we can call the list of cats please?

Hi Zoe,
The only way to grab all the categories would be via an SQL query:
global $wpdb;
//Get the categories
$sql = "SELECT * FROM " . EVENTS_CATEGORY_TABLE;
$categories = $wpdb->get_results($sql);

Cheers, I’ve done that. Here’s my code incase it’s useful to anyone else:
In functions.php:
function get_event_cats() {
global $wpdb;
$use_sql = “SELECT * FROM wp_events_category_detail”;
$thecats = $wpdb->get_results($use_sql);
$output = $output.”<ul class=\”menu-categories\”>”;
foreach ($thecats as $cat) :
$output = $output.”category_name.”\”>”.$cat->category_name.”“;
endforeach;
$output = $output.””;
return $output;
}
I then created a new page template (page-event-cat.php), assigned it to a new page and place the following in the template (mine is outside the “while” for the page content):
<?php echo do_shortcode(‘[EVENT_ESPRESSO_CATEGORY event_category_id=”‘.$_GET[‘catname’].'”]’); ?>

Hi,
Thanks for sharing your code. For future readers, please note it is probably best to use
"SELECT * FROM " . EVENTS_CATEGORY_TABLE;
rather than
“SELECT * FROM wp_events_category_detail”;
As your database may not use the wp_ prefix.

Well spotted! Or I would normally use $wpdb->prefix to call the table prefit ahead of the table name. Is EVENTS_CATEGORY_TABLE a variable built in to event espresso? Is there a list of these anywhere for future reference?
Cheers 🙂

Yeah, all of Event Espresso’s database tables are defined in espresso.php. If you look on line 246 in the current version you’ll see all them defined there.
