Without knowing the surrounding code, it is hard to tell what the problem might be, but you said you checked the $post variable. Maybe the $post variable is not set properly, the save_post action only gives you the post id: function get_post_title($post_id) { $post = get_post($post_id); if (empty($post->post_title)) { // No title set, put in … Read more
You can check if there is any meta for the current post by using get_post_meta So to hide/show the div you would wrap your code in an if statement like this… <?php if( get_post_meta(get_the_ID()) ) { ?> <div> <?php the_meta(); ?> </div> <?php } ?>
While fetching the custom fields details added using ACF, you need to use the functions from the plugin. Use the_field to echo the value and get_field to retrieve the value. Here you can use <p><?php echo get_field( ‘show_this_tomorrow’, $prev_post->ID ); ?></p> or <p><?php the_field( ‘show_this_tomorrow’, $prev_post->ID ); ?></p>
Performace on 1 million plus meta fields vs 1 field with 1 million multi array
This is the way I always do it… add_action( ‘save_post’, ‘header_setting_generate’, 99 ); function header_setting_generate($post_id) { global $post; if(isset($_POST[‘post_type’]) && ($_POST[‘post_type’] == “page”)){ $value = array( ‘header-settings’ => ‘page-data’, ); update_post_meta( $post_id, ‘_skoty-page-header-settings’, $value); } } After inserting this code, go to “Pages”, Select All, click Bulk Edit, Change status to “Published” just to trigger … Read more
update_post_meta returning false when called during init
You need to escape data while displaying also. Use esc_attr in your case. Try this: <input type=”text” name=”field_name” value=”<?php echo (!empty($field)) ? esc_attr( $field ) : ”; ?>” /> Check this for full documentation – https://codex.wordpress.org/Data_Validation
I agree with kraftner’s comments to the question. This is a bad idea and you stand a good chance of regretting it later. Store you data as granular post meta values. Everything is easier later on. However, add_post_meta() and save_post_meta() will serialize objects/arrays for you. You don’t have to do anything special: update_post_meta(1,’my_bad_idea’,array(‘i’,’will’,’regret’,’this’,’later’)); And get_post_meta() … Read more
Problem serializing single quote and double quote into post meta
In general WordPress posts do not represent continuous process. They and their data capture the state of certain point in time (last edit). While there is a WP Cron mechanism for scheduled and (optionally) recurrent operations, it’s poorly suited for periodic post manipulation. For a large amounts of posts it would take either excessively long … Read more
