How to hook into eventTop
Last Updated: July 11, 2018
Since the eventON version 2.2.23 we have added several hooks that you can use to add content to eventTop 2 locations. Let’s take a look at how to add some text in the eventTop. Add the below codes to function.php
1 2 3 4 5 6 |
// hook into event top correct place add_filter('eventon_eventtop_one', 'eventon_insert', 10, 3); function eventon_insert($array, $evvals, $passval){ $array['custom'] = array('eventid'=>$passval['eventid'], 'evvals'=>$evvals); return $array; } |
Explanation:
This part will hook into the first available place in eventTop in the order of other eventTop content. — Which is right under the eventTop categories and other information. You can also use eventon_eventtop_two hook which would add your content to the eventTop right after span.evcal_desc3, (which would be under all the eventTop event data) — but in this example our content will get added into the span.evcal_desc3
Also the variables passed into above function are:
$array – array of other event top items added before this
$evvals – event post meta values as an array
$passval – this contain an array of (‘eventid’, ‘ri’,’fields_’,’fields’) – event id, repeat interval of the current event, event top fields

// include in index as part of event top array add_filter('evo_eventtop_adds', 'eventon_top_adds', 10, 1); function eventon_top_adds($array){ $array[] = 'custom'; return $array; } |
Explanation:
In this we include our element index as custom for the switch statement in eventon-eventTop.php — so the custom index would also run through in the switch statement. (in includes/eventon-eventTop.php line 24)

// throw html content for the switch statement for this index add_filter('eventon_eventtop_custom', 'eventon_top_content', 10, 3); function eventon_top_content($object, $helpers, $EVENT){ $event_id = $object->eventid; // $event_id = $EVENT->ID -- event ID can also be get from this // $event_pmv = $object->evvals; // event post meta values // your HTML code goes in here. $output = '<span data-eventid="'.$event_id.'" class="custom_code">Click to see more</span>'; return $output; } |
Explanation:
This is where we output the HTML when switch statement (mentioned above) get to run on our custom index which would run the filter eventon_eventtop_custom() and that would run this function and output HTML content. One other thing to note here is, $event_id and $event_pmv (event post meta) are variables available for you to use in your HTML.

// styles for the new addition add_action('wp_head', 'eventon_additional_styles'); function eventon_additional_styles(){ echo "<style type='text/css'> body .eventon_list_event .evcal_desc .custom_code{ background-color:#7DC1DF; padding:3px 8px; border-radius:5px; display:inline-block; font-size:12px; text-transform:uppercase; color:#fff; } </style>"; } |
Explanation:
In order to give the final touch we add some styles targeting the new content — <span> with class name custom_code.(in this example) In here we hook the styles to throw in the header of the webpage using wp_head but you can also use other ways to write these styles.
Final Result
The above code saved in your theme function.php will produce a final result like what you see above. This is just an example and you can do more with similar code.
