What is the cleanest way to extract custom variables from a post

So your code is correct. You’d get the exact same thing if you did something like this: $test = array( “1”, “2”, “3” … Read more

Ordering posts by date custom field
In your $args array, “meta_key” should be “event_time”. If you want to get events after a certain date you also have to set meta_value to the desired date and meta_compare to >, <, etc..

trim custom field text value and show (…)
building on keatch’s answer you only need to trim if its longer the 25 chars so: $trim_length = 25; //desired length of text to display $custom_field = ‘my-custom-field-name’; $value = get_post_meta($post->ID, $custom_field, true); if ($value) { if (strlen($value) > $trim_length) $value = rtrim(substr($value,0,$trim_length)) .'(…)’; echo $value; }

Upcoming Event: How do I sort database by custom date field, but ignore past dates?
You’re pretty close, but I wouldn’t be distracted by the ‘scope’ meta key. The following is untested. <?php $args = array( ‘post__not_in’ => array($donotrepeat), “post_type” => ‘event’, ‘meta_key’ => ‘_event_start_date’, // name of custom field ‘orderby’ => ‘meta_value’, “order” => ‘ASC’, “posts_per_page” => 1, ‘meta_query’ => array( array( ‘key’ => ‘_event_start_date’, ‘value’ => date(‘Y-m-d’), ‘compare’ … Read more
