You need to pass get_user_meta a third parameter to prevent it from returning an array. That is where the mistake is, not with the add/update functions. $invoice_meta = get_user_meta( $_GET[‘id’], ‘invoices’, true); You will need to clean up any data already in the database or the existing nested arrays will still cause trouble.
Are you looking for this? function convertInterestCategory() { $interest_categories = array( ‘interest_disaster’, ‘interest_animals’, ‘interest_women’, ‘interest_seniors’, ‘interest_hunger_health’, ‘interest_education’, ‘interest_environment’, ‘interest_arts_culture’, ‘interest_children_youth’, ‘interest_other’, ‘interest_mentoring’, ‘interest_poverty_urban’ ); $current_user = wp_get_current_user(); $user_values = get_user_meta( $current_user->ID ); foreach ( $interest_categories as $interest_category ) { if ( isset( $user_values[$interest_category][0] ) ) echo $user_values[$interest_category][0]; } }
{// post_list case ‘post_list_produktkrav’: $items = get_posts( array ( ‘post_type’ => $field[‘post_type’], ‘posts_per_page’ => -1 )); foreach($items as $item) { echo ‘<input type=”checkbox” value=”‘.$item->ID.'” name=”‘.$field_related[‘id’].'[]” id=”‘.$item->ID.'”‘,$meta_related && in_array($item->ID, $meta_related) ? ‘ checked=”checked”‘ : ”,’ /> <label for=”‘.$item->ID.'”>’.$item->post_title.'</label><br />’; } // end foreach break;}

Update Post Meta for Arrays — Remove/Replace Single Value from Multi Dimensional Array
I think this is what you’re looking for: $$arr_name = array(); If $arr_name = ‘post_title’, then the above would mean: $post_title = array();
From the PHP manual: Variable names follow the same rules as other labels in PHP. A valid variable name starts with a letter or underscore, followed by any number of letters, numbers, or underscores. As a regular expression, it would be expressed thus: ‘[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*’ Hence before diving into your code further: It would need much … Read more
It looks like the problem is here: ‘terms’ => $term where in your case it’s like: ‘terms’ => “array( ‘peoria’, ‘adams’ )” but it should be like ‘terms’ => array( ‘peoria’, ‘adams’ ) By looking at your code snippet, you could try ‘terms’ => explode( ‘,’, $term ); since explode will return the array you … Read more
Try this after your $wpdb query: // collect calendar id’s $ids = array(); foreach( $calendar_entries as $calendar_entries): array_push( $ids, $calendar_entries->id ); endforeach; // query the above calendar id’s $args = array( ‘post_type’ => ‘post’, ‘post__in’ => $ids, ‘orderby’ => ‘id’, ‘order’ => ‘DESC’ ); $query = new WP_Query( $args ); You can also modify the … Read more
Try it like this: if ( $query->have_posts() ) { $categories = $category_ids = array(); while ( $query->have_posts() ) { $query->the_post(); foreach ( ( get_the_category() ) as $category ) { if ( ! in_array( $category->term_id, $category_ids ) ) { $category_ids[] = $category->term_id; $categories[] = $category; } } }; } get_the_category() returns an array of objects.
