$_SERVER[‘REQUEST_URI’] will not be empty in WordPress, because it is filled in wp_fix_server_vars() (file wp-includes/load.php). This function is called in wp-settings.php before any plugin is loaded. So you can use it. But always escape the value. It is global and can be changed by any other code, so you cannot trust its value. A different … Read more
$my_url=”my/relative/url.php”; echo site_url($my_url); site_url() when used by itself will return the absolute path to your blog. But, if you add an argument to it, as per my example above, it will prepend the absolute path to your path. Just make sure your URL doesn’t contain a leading slash (eg: /this/may/not/work). Finally, if you happen to … Read more
It depends on your image and stylesheet location. But this is the syntax: .theme-image { background-image: url(‘../images/header-img.jpg’); } The above code is for the structure wp-content – themes – your-theme – images – header-img.jpg – css – style.css You are making the browser come one directory before and search for images directory.
Surprised to see this unanswered for this long. This is pretty simple to do with a simple block of code: function set_my_nice_name() { global $wpdb; $user_table = $wpdb->prefix . ‘users’; $wpdb->query(“UPDATE $user_table SET `user_nicename`=`ID`”); } add_action(‘init’, ‘set_my_nice_name’); This works because the visible portion of an author slug (or profile slug in BuddyPress) uses the user_nicename … Read more
Okay… here’s how you add the rule. <?php add_action(‘init’, ‘add_my_rule’); function add_my_rule() { add_rewrite_rule(‘^test\/link.*$’,’index.php?pagename=about’,’top’); } ?> This rule will ensure that when you visit a url like http://…/test/link or http://…/test/link<xyz>, you are redirected to the about page (please make sure the slug for about page is ‘about’). Also, http://…/test/, will take you the test page … Read more
I did something similar recently. 1. If the user is not logged in I captured the desired/destination page’s URL and added it as a query arg to the login page’s URL. 2. Redirect the user to the login page. function wpa_59205_redirect(){ global $post; if ( ! is_user_logged_in() ) { // this will tack on the … Read more
That happens because WordPress reads your old post name as category name now – and it cannot find that category. Solution: filter 404_template and try to find the post and its permalink. Then redirect. <?php # -*- coding: utf-8 -*- /* Plugin Name: Redirect to category */ add_filter( ‘404_template’, ‘t5_redirect_to_category’ ); function t5_redirect_to_category( $template ) … Read more
If I understand your question correctly, you want to be able to get the parameter from the url, add it to the shortcode so you can add the parameter to the content. See if this works: add_shortcode(‘name’, ‘get_name’); function get_name() { return $_GET[‘name’]; } In the wordpress backend editor you would have something like: Hello … Read more
To encode the URL, you could use the PHP urlencode( $url ) function or use the WordPress urlencode_deep( $array | $str ); function. add_shortcode( ‘dynamic_contact_button’, ‘button_product_page’ ); function button_product_page() { global $product; return urlencode( “https://wordpress.stackexchange.com/contact-form/?products=Product:%20” .$product->get_title(). “&#contact_form” ); } links: WordPress – urlencode_deep urlencode
You can get the value of front in the global $wp_rewrite: global $wp_rewrite; echo $wp_rewrite->front; // or echo home_url( $wp_rewrite->front ); Though that is probably of limited use, as the front base isn’t necessarily an existing page, and may 404 in many cases. If you’re using that value to prepend to other URLs, you’re likely … Read more
