Fields in database tables can not contain other types of data than text strings and numbers, and variations of them like dates and times. The field meta_value of wp_postmeta is a text field. So, when you store an array as meta_value you are really storing a string containing the serialized data that represents the original … Read more
Looking at your code – $lastarray will not be an array of ID’s (as you might be expecting), but an array with a single element containing a string of comma separated IDs. $output is already an array of the $attr[‘id’] – try commenting (add // to the start) to the lines starting with $testarray and … Read more
Two things need to be changed 1 – wishlistPost.metadata.wishlist_array which is the metadata returns an object with a string inside, not an array. var wishlist_array = wishlistPost.metadata.wishlist_array[0]; //Get current string wishlist_array += postID + “,”; //Concat new ID to the current string 2 – JSON.stringify(wishlist_array) is not needed as stated above wishlist_array is a string … Read more
Good news! I think you’re making things harder for yourself than they need to be. If I understand your question, you’re looking for rewind_posts(). The always useful Digging Into WordPress has a nice summary of it. Because both tasks involve looping through the same query, you don’t need get_posts() at all. Instead, you’ll want to … Read more
From codex: $meta_value (mixed) (required) The value of the custom field you will add. An array will be serialized into a string. Default: None So <?php add_post_meta(7, ‘fruit’, ‘banana’, ‘apple’, ‘tornado’, ‘bob saget’) To grab them you can also use http://codex.wordpress.org/Function_Reference/get_post_custom_values besides just get_post_meta.
The key to using WordPress outside of WordPress is include the wp-load.php file: So your code will like: <?php // Include the wp-load’ include(‘YOUR_WP_PATH/wp-load.php’); // Update post 1 hello word $my_post = array( ‘ID’ => 1, ‘post_title’ => ‘This is the updated post title.’, ‘post_content’ => ‘This is the updated content.’, ); // Update the … Read more
I found the answer. Multiwidget is a nice new feature within wordpress’ new widget API. Yet there is sparse documentation on how to use it. $options = get_option( ‘your_option_id’ ); if( isset($options) && isset($options[$this->number])) { //$this->number returns the unique widget id that corresponds to the database index $instance_options = $options[$this->number]; } //now use $instance_options[‘setting’]
Looking at your code you are calling the function ghoolo_mango() by using the the wp actoin hook. This is fine but be aware that it will add your post everytime a page loads. The problem is that you are also calling the function ghoolo_mango() within the function itself – i.e. it will keep calling it … Read more
First off, there’s a problem with your array. Arrays can not have duplicate keys. So, only the first key will be saved. You need to change your form to something like this. <input name=”mainStageSatOrder[theband0][theid]” type=”hidden” class=”band-id” value=”” />”; <input name=”mainStageSatOrder[theband0][theorder]” type=”hidden” class=”band-order” value=”” />”; <input name=”mainStageSatOrder[theband1][theid]” type=”hidden” class=”band-id” value=”” />”; <input name=”mainStageSatOrder[theband1][theorder]” type=”hidden” class=”band-order” value=”” … Read more
The following function shows you some “best practice” example 😉 It includes error handling, checking for emtpy array values, parsing input args with defaults, cares about if you want to echo the result, etc. You even got a filter for your child themes defaults. 🙂 The function in your functions.php file: function wpse15886_check_cat( $args = … Read more
