register_activation_hook() only attaches a function to run on activation of your plugin, not on updating. See the docs for full details, particularly this part: 3.1 : This hook is now fired only when the user activates the plugin and not when an automatic plugin update occurs (#14915). Of course, you could force your hook to … Read more
I never personally tried this, but your images and posts reside in your {prefix}posts (wp_posts) table. I would also copy {prefix}postmeta (wp_postmeta) over. So copying over those table should do what you want. Keep in mind that this won’t copy your categories and tags (meta), and your comments (comments) they reside in other tables, you … Read more

Try: function vw_postcode_checker_create_db () { global $wpdb; // Create Table Name $table_name = $wpdb->prefix . “vw_postcode_checker”; // Write Query to add table to database if ( $wpdb->get_var(“SHOW TABLES LIKE ‘$table_name'”) != $table_name) { $sql = “CREATE TABLE $table_name ( id INTEGER(10) UNSIGNED AUTO_INCREMENT, postcode varchar(250) DEFAULT ” NOT NULL, area varchar(250) DEFAULT ” NOT NULL, … Read more
The rule of thumb is to never do anything which is not triggered by action or filter. In this case you try register a hook before wordpress even finished to “boot”. This may work sometimes, but totally not an healthy idea. Use at least the ‘init’ hook (and even better the ‘wp_loaded’ if you can), … Read more
Your dot and quote notation is funky. Try this: if($wpdb->get_var(“SHOW TABLES LIKE ‘$table_name'” ) != $table_name){ $sql= “CREATE TABLE $table_name ( id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, firstname VARCHAR(30) NOT NULL, lastname VARCHAR(30) NOT NULL, email VARCHAR(50), reg_date TIMESTAMP );”; require_once (ABSPATH. ‘wp-admin/includes/upgrade.php’ ); dbDelta($sql); }
If you use get_post_meta in the template, that calls get_metadata with meta type post, which contains the filter get_{$meta_type}_metadata, which in this case will be get_post_metadata. There you can check the key and return whatever data you want. function wpd_fake_meta( $meta_data, $object_id, $meta_key, $single ){ if( ‘somekey’ == $meta_key ){ return ‘somefakevalue’; } return null; … Read more
This is the menu_order. You can sort by multiple values too. // Example ‘orderby’ => ‘title menu_order’
There are two ways to edit the wp_posts table that I know of. The first is with the wp_update_post() and wp_insert_post() functions. These are typical WP functions that are used like any others. You just have to pass the correct parameters. For example: $my_post = array( ‘ID’ => $updatePostID, // User defined variable; the post … Read more
I have created an example of how you can achive what you are after: You can use it like this : [itable data=”inv;coin;coinamount;currency#inv;coin;coinamount;currency”] function itable_shortcode( $atts ) { extract( shortcode_atts( array( ‘data’ => ‘none’, ), $atts ) ); $data = explode(‘#’,$data); $output = “”; foreach ($data as $value) { $output .= ‘<tr>’; $in_value = explode(‘;’,$value); … Read more
