Yeah thx, but not quite what i need. I need a way to generate acf admin files, and i only have my php code to work with.

I was wondering, is there any way, for example, to generate a json file, using the php code i have, and then import them again, so they show up in the backend.

Hi, i’m looking for the exact same thing.
I created a fields using ACF in the wp-admin area, then I exported them via php.

Later ( by mistake ) i overwritten my database, and now I can’t edit the fields in the wp-admin, only via php.

Is there any way i can register them again, using the php code i have.
I need this only once, later i will edit them in the wp-admin area.

John, thank you for your help, i figured out what the problem was, after I used your meta_query code, it didn’t work, but then I started to do a bit more research, and it turns out the problem was in the $value var.

I changed
$value = explode(',', $_GET[ $name ]);

to $value = $_GET[ $name ] and it worked flawlessly.

To help anyone else, my whole code was:

function lang_pre_get_posts( $query ) {

    // array of filters (field key => field name)
    $GLOBALS['my_query_filters'] = array( 
        'field_1'	=> 'event_country'
    );
	
	// bail early if is in admin
	if( is_admin() ) {	
		return;
	}
	
	// get meta query
	$meta_query = $query->get('meta_query');

	// loop over filters
	foreach( $GLOBALS['my_query_filters'] as $key => $name ) {
		
		// continue if not found in url
		if( empty($_GET[ $name ]) ) {
			continue;
		}

		if( ! $query->is_post_type_archive() ) return;
		
		// get the value for this filter
		$value = $_GET[ $name ];
		
		// append meta query
        $meta_query[] = array(
          'relation' => 'OR',
            array(
              'key' => 'event_country',
              'value' => '"'.$value.'"',
              'compare' => 'IN'

           ),
            array(
              'key' => 'event_country',
              'value' => '"'.$value.'"',
              'compare' => 'LIKE'
            ),

        );
        
	} 

	// update meta query
	$query->set('meta_query', $meta_query);
}

add_action('pre_get_posts', 'lang_pre_get_posts', 10, 1);

Yes, the field was changed multiple times, from single select field, to multi select field, and to plain text field.

Every time I changed the field, I updated the values again, so it would overwrite the old ones.

No, i tried that already.
The values are stored by a multi-select field, so it gives an array.

I tried with:

        $meta_query[] = array(
                'key'		=> $name,
                'value'		=> '"'.$value.'"',
                'compare'	=> 'LIKE'
        );

also tried to change the ‘key’ manually to only one value (“event_country”), and tried with the solution you gave me above (3. Multiple custom field values), by modifying code like this :

‘meta_query’ => array(
‘relation’ => ‘OR’,
array(
‘key’ => $name,
‘value’ => ‘”‘.$value.'”‘,
‘compare’ => ‘LIKE’
),
array(
‘key’ => $name,
‘value’ => ‘”‘.$value.'”‘,
‘compare’ => ‘LIKE’
)
)
