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
You can use explode() or preg_split(), like this: $i = 0; foreach( $namesArray as $key => $name ) { $arr = explode( ‘ -‘, $name, 2 ); //$arr = preg_split( ‘/\s+\-/’, $name, 2 ); $name2 = isset( $arr[0] ) ? trim( $arr[0] ) : ”; $role_name = isset( $arr[1] ) ? trim( $arr[1] ) : … Read more
In PHP, the number 0 is interpreted as false-ish. Your if-statement asks for a true-ish condition like this: If the result of the array_search function is interpreted as true-ish, THEN do the stuff which means if the result is 0, it is interpreted as false, and the code doesn’t run. What to do? Use the … Read more
What you need to use is comment_form_defaults filter that has large and nested $defaults array passed. That array will have (among other things) something like this in it: fields author << this will have something like <span class=”required”>*</span> in it email << this will have something like <span class=”required”>*</span> in it url comment_notes_before << this … Read more
In PHP, there is no need to use the square brackets that are required in an HTML form name to indicate an array, such as you get when using checkboxes. In other words, this in HTML: <label><input type=”checkbox” name=”brand[]” value=”1″> Brand 1</label> <label><input type=”checkbox” name=”brand[]” value=”2″> Brand 2</label> <label><input type=”checkbox” name=”brand[]” value=”3″> Brand 3</label> Will … Read more
