Im having an issue with inserting data into the wordpress database through my plugin. My plugin uses a shortcode to display a form from which some calculations are made and then that information is the then supposed to be inserted into the database but I end up getting this message. I can't seem to get it to work?.. Any help would be appreciated greatly. PLUGIN CODE used for the insert: include_once($_SERVER['DOCUMENT_ROOT'].'/wp-config.php' ); $wpdb->insert( 'wp_wine_bookings', array( 'name' => $_POST['name'], 'last_name' => $_POST['lname'], 'phone_number' => $_POST['phone_num'], 'email' => $

hey guys, maybe some of you have experience with programming wordpress plugins. I have a probably rather simpel question, but i couldn't find anything on the web. <?php /* Plugin Name: test */ function test($content) { echo $post_id; return $content; } add_filter('the_content', 'test'); ?> I have a simpel plugin that should echo out the unique ID of every post in it's content. So on my frontpage with 10 posts every post should have it's ID echoed out. Any idea how to achieve that? thank you! My guess is Use global keyword to access post id in function And also my guess is return and echo both

My buddy wants to create a WordPress blog, but because he's picky about the design (specifically the fonts), he wants to use Flash for the frontend -- display, content creation, user interface, etc. He's looking for a plug-in that will take the user input from the Flash interface and convert it into the appropriate PHP for WordPress. I've never used Flash, so I didn't know what to tell him, other than that this sounds nuts. Is there a better answer than this? Flash can store and retreive information via HTTP easily enough, and I think Wordpress makes most things available via an XML-RPC

Since PHP mail has been disabled on my server it has stopped a theme integrated contact form from working. The theme is called Boldy and it has its own sendmail.php file which uses mail() instead of wp_mail() . Changing mail() to wp_mail() does not work, but I'm not sure why? <?php if (isset($_POST['submit'])) { error_reporting(E_NOTICE); function valid_email($str) { return ( ! preg_match("/^([a-z0-9\+_\-]+)(\.[a-z0-9\+_\-]+)*@([a-z0-9\-]+\.)+[a-z]{2,6}$/ix", $str)) ? FALSE : TRUE; } if ($_POST['name'] != '' && $_POST['email'] != '' && valid_email($_POST['email']) == TRUE && strlen($_POST[

I'm working on a wordpress plugin(managing background image), when I try to use global $post; print_r($post); the object is empty. Probably there is some required data (I dont know what.) Please help me if you know. The WordPress global variable $post contains the data of the current Post within the The Loop . This means that WordPress will assign a value to this variable in each loop iteration. Consecuently, if you're trying to access $post from anywhere in your code outside the WP loop, it will be of course empty... 来源： https://stackoverflow.com/questions/22745077/wordpress-global-post

is it possible to change product price in Woocommerce Mini Cart Widget? I've overrided price in cart using tips from WooCommerce: Add product to cart with price override? but it only works for cart page. Prices in widget are not changed. This is how I set price to 0 for free products: function set_free_items_price( $price, $cart_item, $cart_item_key ) { $returned_item_price = $cart_item['data']->get_price(); if (isset($cart_item['free_item']['value']) && $cart_item['free_item']['value'] == true) { $returned_item_price = 0; } return get_woocommerce_currency_symbol() . $returned_item_price; } I
