You can use Php’s usort() function with a callback. For example, if you want to sort images by ID, you could try something like this (stealing the filter that @Milo used in their answer): <?php function sort_callback($a,$b) { if ($a[‘id’] == $b[‘id’]) { return 0; } return ($a[‘id’] < $b[‘id’]) ? -1 : 1; } … Read more
I’m pretty sure that you ARE incorrect. Let’s taka a closer look at this code you mentioned in your question. In first line it sets $where variable: $where=”WHERE ID IN (” . substr(str_repeat(‘%d,’, count($my_options[‘acf_posts’])), 0, -1) . ‘)’; So what this line really does is: get the number of some options (let’s call it ‘N’) … Read more
Both the_permalink() and the_sub_field() are functions that do more than output a string or URL. Try usingget_permalink() and get_sub_field instead: $link1 = get_permalink(); $link2 = get_sub_field(‘link_url’);
The page link field actually stores the post ID, which gets formatted internally by the get_field function on output. The 3rd argument for get_field lets you disable that output formatting so you just get the ID back, which you can then use to get title and permalink for that post: $post_id = get_field( ‘bookitall_roomstype’, false, … Read more
thanks to @kero, i managed to do something like this : <?php $dayNumber = “l”; $weekDay = “j”; $month = “F”; $year = “Y”; $unixtimestamp = strtotime(get_field(‘date’)); ?> <?php echo ‘<span>’ . date_i18n($dayNumber, $unixtimestamp) . ‘</span>’; ?> <?php echo ‘<span>’ . date_i18n($weekDay, $unixtimestamp) . ‘</span>’; ?> <?php echo ‘<span>’ . date_i18n($month, $unixtimestamp) . ‘</span>’; ?> … Read more
You can do this instead of using update_field(): update_post_meta($post_id, ‘fieldname’, $value); update_post_meta($post_id, ‘_fieldname’, ‘field_’ . uniqid()); // `uniqid() is a native PHP function. This is also how ACF creates the field keys Also, depending where you are retrieving the value, you may also have to pass the post id. the_field(‘fieldname’, $post_id);
Find the first occurrence of a custom field
Here’s how ACF keeps attachment data: meta_id post_id meta_key meta_value 971 931 doors 666 972 931 _doors field_25 As you can see if you’re using get_post_meta it will only ever be able to return you an ID. Since not using get_field you’ll need to do the extra step of getting attachment metadata yourself: $meta_one = … Read more
Migrating data from ACF to WordPress custom meta boxes
You should look at archives.php. What you trying to do is create a custom post type loop (“pages) in different sections of your template. You have to filter by category, taxonomy, or tags to set up your different groupings. http://www.wpbeginner.com/wp-tutorials/how-to-create-a-custom-post-types-archive-page-in-wordpress/ https://stackoverflow.com/questions/30883218/custom-post-type-wordpress-query-by-category I think this is what I mean: List all posts in custom post type … Read more
