WordPress automatically serializes/unserializes the data when it’s stored and retrieved, all you need to do is pass a php array as your data and you’ll get the same array back when you get_post_meta. $data = array( ‘label’ => ‘something’, ‘desc’ => ‘someval’, ‘id’ => ‘someval’, ‘type’ => ‘someval’ ); update_post_meta( $post_id, ‘your_key’, $data ); $data … Read more
If you have the CPT’s ID in the $event_id variable you plug into the get_post() call – why would you not simply just (re)use that for the first parameter of get_post_meta() ? That aside, get_post() returns a post object (instance of WP_Post), which you choose to assign to $event. Hence $event now has a public … Read more
The best way would be to use the built-in Options API to add info to the wp_options table. To add the option: http://codex.wordpress.org/Function_Reference/add_option To read the option value: http://codex.wordpress.org/Function_Reference/get_option
Your issue seems to be with too loose logic check, rather than saving. To treat valid but falsy value correctly you need something like this: if ( false !== $meta_value ) This will strictly match only the case when value doesn’t contain false (return of the API when fetch failed).
That field is longtext so it should be more than you could ever use– about 4GB
You are talking about “Options”. These are saved in the *_options table and can be stored and retrieved using a number of Core functions (straight from the Codex page above): Add/Delete Option add_option() delete_option() add_site_option() delete_site_option() Get/Update Option get_option() update_option() get_site_option() update_site_option()
Define your own template tag One idea is to use the template tag: <?php the_price();?> or <?php the_price( ‘%.1f’ );?> to change the format to your needs. Then you can add filters to it as you like. In your functions.php file you could add // setup the price filters: add_filter( ‘the_price’ , ‘xyz_add_product_price’, 1, 1 … Read more
Your main problem is that when you list your events, you (most probably) use the the_permalink() function to get the url of the single event. When this url is called, WordPress show the single event, but how can WordPress know if the link was clicked in the page-events.php or in the page-media.php? If you don’t … Read more
I noticed that your are using get_the_content(), but it will return unfiltered content. The shortcodes are generated via the the_content filter with priority 11. So if you want only the shortcodes generated, try: ‘content’ => do_shortcode( get_the_content() ) to filter it through the_content filter, try: ‘content’ => apply_filters( ‘the_content’, get_the_content() ) to simulate the_content() function, … Read more
I am guessing but based on your choice of placeholder names in the code above… $args = array( ‘meta_key’ => ‘myvalue’, ‘orderby’ => ‘meta_value_num’, ‘order’ => ‘DESC’ ); … your meta_key argument is wrong. That is the meta key not the meta value as your naming convention suggests. meta_key (string) – Custom field key. http://codex.wordpress.org/Class_Reference/WP_Query#Custom_Field_Parameters … Read more
