PHP interprets those arrays differently. In the first example you’re asking WP_Query to get postsby 3 term slugs and in the second example you’re assigning the array a value of 1 string. If we were to print the two arrays it would look like this: Your Example 1: ‘terms’ => array( [0] => ‘The A … Read more
You need to put the id of each item inside form to indicate the item that will be deleted. <?php $all_favorites= unserialize($_COOKIE[‘favorites’]); echo ‘<table>’; foreach($all_favorites as $key => $value) { echo ‘<tr>’; echo ‘Post-ID = ‘ . $value . ‘ ‘; ?> <form method=”POST”> <input type=”hidden” name=”id” value=”<?php echo $value; ?>”> <button type=”submit” class=”btn btn-default” … Read more
Let’s analyze your code and what it does. Assuming that the current fruits stored in the database are ‘pineapple’ and ‘orange’, get_user_meta(2, ‘fruits’, false) will return something like this: array( array( ‘pineapple’, ‘orange’ ) ) This is because you passed false as the third argument, $single. The function returns an array if $single is false … Read more
You have a problem with your query which is you can’t use GROUP BY and ORDER BY before WHERE replace FROM tablename GROUP BY submit_time ORDER BY submit_time DESC with FROM tablename This is your query $results = $wpdb->get_results( ‘SELECT DATE_FORMAT(FROM_UNIXTIME(submit_time), “%b %e, %Y %l:%i %p”) AS Submitted, MAX(IF(field_name=”Name”, field_value, NULL )) AS “Name”, MAX(IF(field_name=”Email”, … Read more
Found the solution: $currentProducts = $wpdb->get_results(“SELECT feedid, id, size, price FROM products WHERE shopid = $shopid”, OBJECT_K); The OBJECT_K parameter makes an associative array with feedid as key: https://codex.wordpress.org/Class_Reference/wpdb#SELECT_Generic_Results
Here’s my approach… First you have to select 3 latest posts, then you have to pick random one of them… But it’s easier to shuffle selected posts than picking only one of them – that way you can still use normal loop: <?php $args = array( ‘post_type’ => ‘post’, ‘posts_per_page’ => 3, ‘post_status’ => ‘publish’ … Read more
You are overwriting $post_ids variable on every while loop, never collecting them. That can be solved using $post_ids = array(); while (have_posts()) : the_post(); $post_ids[] = get_the_ID(); endwhile; var_dump($post_ids); // this is an array of ids However there is simpler way, you can skip the whle cycle and simply run: if( function_exists( ‘wpseo_local_show_map’ ) && … Read more
If you check out the documentation for the update_user_meta() function, you’ll note that the $meta_value parameter already accepts objects and arrays, so you can simply save a user’s positions in an array without any additional effort: update_user_meta( 22, ‘position_names’, array( ‘Khaleesi of the Great Grass Sea’, ‘Breaker of Chains’, ‘Mother of Dragons’ ) ); The … Read more
Try this php built-in function array_walk_recursive function wpse_do_something_on_data() { $data = array( ‘repeater-1’ => array( array( ‘user_defined_field1’ => ‘http://www.domain-001.com’, ‘user_defined_field2’ => ‘http://www.domain-002.com’, ), array( ‘user_defined_field1’ => ‘http://www.domain-011.com’, ‘user_defined_field2’ => ‘http://www.domain-012.com’, ), ), ‘repeater-2’ => array( array( ‘user_defined_field1’ => ‘http://www.domain-101.com’, ‘user_defined_field2’ => ‘http://www.domain-102.com’, ), array( ‘user_defined_field1’ => ‘http://www.domain-111.com’, ‘user_defined_field2’ => ‘http://www.domain-112.com’, ), ), ); array_walk_recursive( $data, … Read more
WordPress has the wp_list_pluck function, which can be helpful here. We can make an array of just term IDs from the array of objects like: $term_ids = wp_list_pluck( $subcat_terms, ‘term_id’ ); Then we can check in_array: $this_id = 42; if( in_array( $this_id, $term_ids ) ){ // do something }
