<?php $meta_values = get_post_meta($post_id, $key, $single); ?> $single (boolean) (optional) If set to true then the function will return a single result, as a string. If false, or not set, then the function returns an array of the custom fields. This may not be intuitive in the context of serialized arrays. If you fetch a … Read more
I tried the following and it works: function wpse_80236_Colorpicker(){ // you forgot this probably it’s the bundled CSS wp_enqueue_style( ‘wp-color-picker’); // wp_enqueue_script( ‘wp-color-picker’); } add_action(‘admin_enqueue_scripts’, ‘wpse_80236_Colorpicker’); Then your input: <input name=”mv_cr_section_color” type=”text” id=”mv_cr_section_color” value=”#ffffff” data-default-color=”#ffffff”> Then the following js: jQuery(document).ready(function($){ $(‘#mv_cr_section_color’).wpColorPicker(); });
update_post_meta() will update the value for the provided key if the key already exists in the database and then returns true, which is what you’re seeing for subsequent calls. It only returns the ID of the post meta if the key didn’t exist previously. If you want to store multiple values (rows) with the same … Read more
Change the line <?php echo apply_filters(‘the_content’, get_post_meta($page->post_content, ‘custom_tagline’)); ?> to <?php echo apply_filters(‘the_content’, get_post_meta($page->ID, ‘custom_tagline’)); ?> See http://codex.wordpress.org/Function_Reference/get_post_meta
You don’t need to call wp_reset_query() here, because you’re not modifying the main query. Instead, call wp_reset_postdata(). You only need to call wp_reset_query() when modifying the main loop via query_posts() (which you shouldn’t do, anyway, so you should never need to call wp_reset_query()). But new WP_Query(), with a properly instantiated loop – i.e. one that … Read more
You are using get_post_meta incorrectly, so it is returning FALSE every time. As PHP equates ‘0’ and FALSE, your div will always be displayed. The correct syntax for get_post_meta is: <?php $meta_values = get_post_meta($post_id, $key, $single); ?> where $post_id is the only required argument.
Short of doing some jQuery validation, I think the only option is wp_die(). add_action( ‘save_post’, array( $this, ‘save_custom_items_data’ ), 10, 2 ); public function save_custom_items_data( $post_id, $post ) { if( count( $related_items ) > 5 ) { wp_die( ‘Error, 5 items max.’, ‘Error’, array( ‘response’ => 500, ‘back_link’ => true ) ); } else update_post_meta( … Read more
When you are in your while loop, the parent query is already finished. So fetch the post meta value with get_post_meta(): $template = get_post_meta( get_the_ID(), ‘_wp_page_template’, TRUE );
Separate the allowed values in a function: function get_allowed_values() { return array(‘one’, ‘two’, ‘three’); } In your metabox: foreach ( get_allowed_values() as $item) {} In your validation handler: if ( isset( $_POST[‘select_meta’] ) and in_array( $_POST[‘select_meta’], get_allowed_values() ) )
Assuming you’re retrieving the posts using a standard WP_Query in some manner, then the postmeta data is automatically retrieved for all the relevant posts and cached in memory. When you later call get_post_meta, the data is simply returned from here. So honestly, it doesn’t make any significant difference which approach you take. The get_post_meta function … Read more
