Get taxonomy list from acf value

  • I have a custom taxonomy called “shops”. I have some custom fields related to the taxonomy. 1 custom field is a checkbox with 3 options: option 1, option 2 option 3

    on my front page i want to show a list of the taxonomy shops only if the value of the custom field is option 1.

    is this possible? If it is possible how do i do that?

    the code i tried is:

    <?php 
    $terms = get_terms("shops");
    $value = get_field('shop_options', 'shops_'.$wp_query->queried_object->term_id);
    if( $value == "option_1" )
    {
     echo 'something';
    }
     ?>
  • Hi @ron Willemse

    The get_terms function will return an array of terms. This means you need to loop through the code and run your if statement for each term like so:

    
    <?php 
    
    $terms = get_terms("shops");
    
    if( $terms )
    {
    	foreach( $terms as $term )
    	{
    		$value = get_field('shop_options', 'shops_'.$term->term_id);
    		if( $value == "option_1" )
    		{
    		 echo 'something';
    		}
    	}
    }
    
     ?>
    

    Hope that helps

    Thanks

  • Thnx for the advice

    if i change

    $value = get_field(‘shop_options’, ‘shops_’.$term->term_id);

    to

    $value = implode(‘, ‘, get_field(‘shop_options’, ‘shops_’.$term->term_id));

    it works

  • only now i get the error Warning: implode(): Invalid arguments passed in (path) on line 6 .

    do i have to put something else in the code?

  • Hi @ron Willemse

    You most likely need to test that the value exists before passing it into the implode function.

  • i can’t figured out what to add to the code if i want to check if the value exists. can you help me?

  • Hi @ron Willemse

    This is called an if statement. Please review the ACF documentation code examples or refer to Google / PHP for documentation about the if statement.

    Thanks

  • i know its a if statement but i don’t know where to put it. I’m not a php developer.

    i tried:

    if ($value){
    $value = implode(', ', get_field('winkel_uitgelicht', 'winkels_'.$term->term_id));
    }

    but that don’t work

  • i found a solution:

    if (is_array(get_field('winkel_uitgelicht', 'winkels_'.$term->term_id))) {
    $value = implode(', ', get_field('winkel_uitgelicht', 'winkels_'.$term->term_id));
