List of slugs from custom post taxonomy for loop

Hello

I have a flexible content field in which I want to display certain events.
The events that are shown should be selected by a taxonomy field where several entries (cities) of a custom post taxonomy (locations) can be selected by checkbox. (multiselect)
The return is an Taxonomy object.
I need a list of the slugs from the selected fields.
The list should be e.g. like: ‘munich’, ‘london’,

The relevant Code is

<?php 
$locations = get_sub_field('select_locations');
$loop = new WP_Query( array( 'post_type' => 'events', 'posts_per_page' => 99, 
	
	
		'tax_query' => array(
			array(
						'taxonomy' => 'locations',
						'field' => 'slug',
						'terms' => array(
							/* HERE SHOULD BE THE LIST */
						)
					)
		) 
) ); 

?>

I tried several things but I can’t get it working.
I would be very happy if someone could help me with this.

Thanks a lot.

I’ve been trying to do something similar. I needed to pull list of category Names and slugs and use them to populate a News feed. I’m sure this is probably not the best way to do it but it worked for me.

	
//vars
$terms = get_sub_field('filter_news_feed');	
	
//set variables for the category slug and category name
$output = "";
$nameOutput = "";

//Loop throuh each item in the array and assign the slug and name values to their variables 
foreach( $terms as $term ):
	$output.= $term->slug . ', ';
	$nameOutput.= $term->name . ', ';
endforeach; 

//trim the last , and space ' ' off of the list
$trimOutput = rtrim($output,', ');
	
//trim the last , and space ' ' off of the list
$trimNameOutput = rtrim($nameOutput,', ');

and then to load it into the array:

$args = array(
  'post_type' => 'post',
  'post_parent' => 0,
  'posts_per_page' => 4,
  'order' => 'DSC',
);
					
//adding 'category_name' => 'slug, slug, slug, etc'; to args array
$args['category_name'] = $trimOutput;

Hope that helps….

Hey Helmet,

thank you for your answer. I allready found a solution with the help of a developer.
It seems quite similar to yours.

Just for anyone who’s interested:
`
<?php
$locations = get_sub_field(‘orte_eingrenzen’);
$locationsSelected = array();
foreach( $orte as $ort ):
$locationsSelected[] = $ort->slug;
endforeach;

$loop = new WP_Query( array( ‘post_type’ => ‘kurse’, ‘posts_per_page’ => 99, ‘meta_key’ => ‘datum’, ‘orderby’ => ‘meta_value’, ‘order’ => ‘ASC’,

‘tax_query’ => array(
array(
‘taxonomy’ => ‘loacations’,
‘field’ => ‘slug’,
‘terms’ => $locationsSelected
)
)
) );
?>
