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
If I am understanding you correctly just change <?php $count=1;foreach ($value[‘options’] as $key => $option) { ?> and you can access the key from $key.
