Trying to get property of non-object in shortocde
You need to call global $post before using $post->ID, or better, use get_the_ID() instead.

Hide sidebar if post_type is in array
This is more php, but you can use in_array(). Just check if the current post type is in array in $hide_sidebar. You can do the following $hide_sidebar = array(‘example1’, ‘example2’, ‘example3’); //hide sidebar on these post types if ( in_array( get_post_type(), $hide_sidebar ) ) { // Do something if the post type is in array … Read more
Get archives as array
If you look at wp_get_archives() you will notice that the link is generated by get_archives_link(). That function supplies a filter that will allow you to replace the parens. This is fairly crude but does work. function archive_link_wpse_183665($link) { $pat=”|\(([^)])\)</li>|”; // preg_match($pat,$link,$matches); // var_dump($matches); $link = preg_replace($pat,'[$1]’,$link); return $link; } add_filter( ‘get_archives_link’, ‘archive_link_wpse_183665’ );
Get html data with javascript to php array and store to wordpress database
Here is my own solution. In my html I’ve assign id to all the item and inside the form I’ve added an input option where I pass the value through the script and it was saved later. Simple… script jQuery(document).ready(function($){ $(“.sortable”).sortable({ connectWith: ‘.sortable’, receive: function (event, ui) { document.getElementById(‘hello1’).value = myFunction(); }, out: function (event, … Read more
How do I turn these values from MYSQL into an array
Use $wpdb->get_col. It will return a one-dimensional array that you can use in post__in $allposts = $wpdb->get_col(“SELECT `music_id` FROM `custom_table` ORDER BY id DESC LIMIT 5”);
Get array of metakey in all posts
Your function is unreliable and totally overboard and really really expensive. Furthermore, as already stated by @MarkKaplun, you are not calling the_post() which causes the $post global not to be updated to the current post being looped through, so the value from get_post_meta() will always have the same value. Although $post_id might work, it is … Read more
Query Custom Post Types with checkboxes
You aren’t constructing the meta_query correctly. It is close but not quite right. $searchArray = array(); $searchArray = array(‘relation’ => ‘OR’,); // here is the change // loop over checked checkboxes if(!empty($_POST[‘course_location’])) { foreach($_POST[‘course_location’] as $check) { // echo ‘<h1>’.$check.'</h1>’; $searchArray[] = array(‘key’ => ‘course_location’,’value’ => $check,’compare’ => ‘LIKE’,); } } As you have it … Read more
Combine results of multiple WP_Query to resemble single WP_Query
I cannot really see doing this than to run a couple of queries here, one per category. We will need to be clever here to avoid a lot of unnecessary work. Lets look at the code; (which I will comment to ease the process of understanding) // Get the categories. We will only get the … Read more
Output meta into arrays
Add ‘fields’ => ‘ids’ to skip setting up the post and just create the array you want in the foreach. $week_args = array( ‘posts_per_page’ => – 1, ‘post_type’ => ‘post’, ‘post_status’ => array( ‘publish’ ), ‘fields’ => ‘ids’, ‘date_query’ => array( ‘before’ => ‘next Saturday’, ‘after’ => ‘last Monday’, ), ); $week_array = get_posts( $week_args … Read more
Filtering a function’ output for a new continued function
How about using a standard for loop instead: $sunnytags = get_tags ($tagargs); $count = count ($sunnytags); for ($i = 0; $i < ($count < 15 ? $count : 15); $i++) { $string .= ‘<a class=”tag2″ href=”‘. get_tag_link ($sunnytags[$i]->term_id) .'”>’. $sunnytags[$i]->name . ‘</a>’; } And then later, whether you re-run the query or (better still) save … Read more
