The answer by felipelavinz assumes that there is an array of dates stored in the post_meta of each post, but the way I read your question and sample code it seemed as though you have one date specified per post? If this is true (one date per post) then the following would suit you better … Read more
Please try this instead: $args = array( ‘post__in’ => $post_ids, ); $posts = get_posts( $args ); Lesson learned: Always check your PHP scripting errors! 😉 Check for example this Codex page on debugging.
You are looking at type casting: http://php.net/manual/en/language.types.type-juggling.php What the code does is caste the value returned by get_option() to an array. It is being done so that array_merge() works correctly and doesn’t trigger warnings/errors. That much is pure PHP and is off-topic. The only reason I chose to answer rather than to post a comment … Read more
It’s not recommended to use query_posts(), check for example this warning note in the Codex: This function isn’t meant to be used by plugins or themes. As explained later, there are better, more performant options to alter the main query. query_posts() is overly simplistic and problematic way to modify main query of a page by … Read more
WordPress provides a default method, wp_parse_args, to combine a set of default options and a user-defined set of options. This method uses PHP’s native array_merge for arrays, but also works when either of the two option sets is an object or a WordPress options string. You simply provide an array of default options and an … Read more
You have a mismatch in your PHP tags. Use this: <?php $field_name = “text_field”; $field = get_field_object($field_name); ?> <table> <tbody> <?php if( isset($field[‘value’] ): ?> <tr> <th><?php echo $field[‘label’]; ?></th> <td><?php echo $field[‘value’]; ?></td> </tr> <?php endif; ?> </tbody> </table>
Your data will be serialized, if you save non-scalar values (e.g. array, object) as post meta. You must unserialize it: $subs = get_post_meta( $post->ID ); $subs[‘_q1_subs’][0] = unserialize($subs[‘_q1_subs’][0]);
If you don’t need to query on the data, you can pass arrays directly to the post meta functions, WordPress will automatically serialize/unserialize the data for you. $your_array = array( array( ‘title’ => ‘something’, ‘price’ => ‘something’, ), array( ‘title’ => ‘something’, ‘price’ => ‘something’, ), ); update_post_meta( $post_id, ‘your_key’, $your_array );
The warning message is pretty clear. You’re passing method amp_support from class Wppr_Public as callback, but this class doesn;t have such method… So how to fix it? You should find that class and look for this function. Maybe it’s some typo or that method changed its name or moved to another class or something like … Read more
OK, so you want to define posts order by yourself. WP_Query allows you to do that – you’ll have to use orderby => post__in to achieve it. And that’s what you do. So why isn’t it working? Because of a typo 😉 Ordering posts by post__in preserves post ID order given in the ‘post__in’ array. … Read more
