How to list all events for current category

    This may be more of a PHP question than something about this plugin specifically.

    I’m beating my head against the wall after a couple days. I must be doing something stupid, but I surrender. I had this working, and after building out more of the site came back to this page and found it broken. Everything I tried to fix it has failed.

    In the event page I want to list all other events for the current event’s category. The basic idea is to call eo_get_events() and pass ‘event-category’=> as the slug for the current post’s category. Note that I do assume there’s only one category. That’s all I care about.

    So I do this:

    $terms = get_the_terms( $post->ID, 'event-category' );

    Then this (which had worked):

    $upcoming = eo_get_events(array(
'event-category'=>$terms[0]->slug

    For some reason, this broke and I’ve been banging my head to get it working again.

    All attempts at PHP have failed me, but I readily admit PHP is a new language for me (yet I have programmed in many others).

    If I use this, it does pull out the slug I’m looking for:

    foreach ( $terms as $term )
  $currentCategory = $term->slug;

    So why does the “foreach” loop work, but EVERYTHING else I’ve tried to access the current slug has failed.

    How can I get to the first occurrence, without looping through the array with foreach?

    FYI – echo var_dump ($terms);

    array(1) { [348]=> object(stdClass)#644 (12) { [“term_id”]=> int(348) [“name”]=> string(48) “BLAH” [“slug”]=> string(9) “THIS_CATEGORY” [“term_group”]=> int(0) [“term_taxonomy_id”]=> int(379) [“taxonomy”]=> string(14) “event-category” [“description”]=> string(46) “BLAH” [“parent”]=> int(353) [“count”]=> int(5) [“object_id”]=> int(9195) [“filter”]=> string(3) “raw” [“color”]=> string(7) “#42217E” } }

    Note – I edited the text of some fields just for this post. Nothing meaningful. It’s the data structure that matters.

    The returned array is indexed by term ID. So to access the first element you’ll need to use array_shift().

    I’m feeling stupid. Can you be more explicit?

    If I do this:

    array_shift($terms);
var_dump ($terms);

    I get this:

    array(0) { }

    And after that I have just more head banging.

    I keep thinking there’s just one or two lines of code that would get me the category slug I’m looking for, to pass to eo_get_events().

    Yup,

    $first_term = array_shift( $terms );
//$terms now has the first element in the array removed
$first_term_slug = $first_term->slug;
