Hi forum,
i ran into an error i can’t figure out.
i have a ACF Options page for my Theme Logo field (returns Array)
it works on every page template except of my archive-cpt.php
i try to sort my cpt by acf field and have this in my functions file
function sort_by_date_termin( $query ) {
if ( is_post_type_archive( 'termin') ) {
$query->set('meta_key', 'datum');
$query->set('orderby', 'meta_value_num');
$query->set('meta_type', 'DATE');
$query->set('order', 'ASC');
return;
}
}
add_filter( 'pre_get_posts', 'sort_by_date_termin', 1);
when i remove this filter the archive-cpt.php gives no errors and the theme logo is normally displayed in the header
when the filter is active i get this error:
<b>Warning</b>: Illegal string offset ‘url’ in <b>/www/htdocs/domain.com/wp-content/themes/mythemename/header.php</b> on line <b>24</b>
Warning</b>: Illegal string offset ‘alt’ in <b>/www/htdocs/domain.com/wp-content/themes/mythemename/header.php</b> on line <b>24</b>
so there must be some conflict with the filter pre_get_posts
this is line 24 in my header.php
$mainlogo = get_field('header_logo' , 'option'); ?>
<img src="<?php echo $mainlogo['url']; ?>" alt="<?php echo $mainlogo['alt']; ?>">
