This is a variable scope problem. Your variable in functions.php is not in scope where you are trying to use it in your footer. To make this work declare the variable global in functions.php global $tst; $tst=”d00d”; And then pull it in with the global keyword when you need to use it. global $tst; echo … Read more
That’s called Ternary Operator. if( ! empty( $_POST[‘variable_b’] ) { $variable = explode( “\n”, trim( $_POST[‘variable_b’] ); } else { $variable = array(); } You can see PHP Shorthand If/Else Using Ternary Operators (?:) for more details.
As Sally highlights, you can use in_array() like this (untested): // target ids $ids = array(123, 321, 213); if (!empty($post->ID) && is_numeric($post->ID) && in_array((int)$post->ID, $ids)) { // do jazz } else { // do stuff }
Since you are storing an url for each image you can create a query to get the id of the attachment based on the guid: global $wpdb; $ids = array(); foreach ($images as $image_url) { $ids[] = $wpdb->get_col($wpdb->prepare(“SELECT ID FROM $wpdb->posts WHERE guid=’%s’;”, $image_url)); } Another way would be to simply store the ID rather … Read more
Setting the proper dataType for the request is an important detail not considered in the answer above (this causes jQuery to send a HTTP Accept header with the request – and it will be expecting JSON data in the success callback as well): dataType: ‘json’, success:function(json){ var content=””; jQuery.each(json, function(i, v){ content += ‘<li>’ + … Read more
$args = array( ‘meta_query’ => array( array( ‘key’ => ‘author_status’, ‘value’ => ‘active’, ‘compare’ => ‘NOT LIKE’ ) ) ); This Url works http://codex.wordpress.org/Class_Reference/WP_Query#Custom_Field_Parameters
Please take a look at this example; $args = array( ‘post_type’ => ‘post’, ‘tax_query’ => array( ‘relation’ => ‘AND’, array( ‘taxonomy’ => ‘movie_genre’, ‘field’ => ‘slug’, ‘terms’ => array( ‘action’, ‘comedy’ ) ), array( ‘taxonomy’ => ‘actor’, ‘field’ => ‘id’, ‘terms’ => array( 103, 115, 206 ), ‘operator’ => ‘NOT IN’ //you must set the … Read more
Not really a WordPress question, but I’ll bite. That data is JSON. To manipulate it with PHP you need to decode it with json_decode(). Then you can treat it as a PHP object. So to access the values you’d mention, and assuming the JSON is in a variable named $json: $object = json_decode( $json ); … Read more
If you are looking to change value of categories, you can just take a vairable instead of taking constant value and increment based on category!
Use this type of code : $args = array( ‘author’ => $publisher_info->ID, ‘post_type’ => ‘post’, ‘tax_query’ => array( array( ‘taxonomy’ => ‘type’, ‘field’ => ‘slug’, ‘terms’ => array( ‘campaign’ ), ) ), ‘meta_query’ => array( ‘relation’ => ‘AND’, array( ‘key’ => ‘status’, ‘value’ => ‘active’, ‘compare’ => ‘=’), array( ‘key’ => ‘B’, ‘value’ => ‘1’, … Read more
