  1. POpost rating system function
    text
    copied!<p>There's code below for simple post rating system (tutorial from this site <a href="http://wp.tutsplus.com/tutorials/how-to-create-a-simple-post-rating-system-with-wordpress-and-jquery/" rel="nofollow">TUTORIAL</a> ) - it works fine but i need to change it a bit. Now where user votes, he is not able to vote again for same post for $timebeforevote (1440 minutes). I want to block user voting for all post not just for this one.</p> <p>I think the problem is function is looking for user ip in current post meta field with this code:</p> <pre><code>$meta_IP = get_post_meta($post_id, "voted_IP"); $voted_IP = $meta_IP[0]; </code></pre> <p>Returns <code>$voted_IP</code> and compares it with <code>$ip = $_SERVER['REMOTE_ADDR'];</code> I tried to modify it with query (where query looks for ip in meta field for all posts) so it would search for ip in all posts but it didn't work. I am trying to make it work for 2 days and nothing works.</p> <p>POST RATING SYSTEM CODE:</p> <pre><code>$timebeforerevote = 1440; add_action('wp_ajax_nopriv_post-like', 'post_like'); add_action('wp_ajax_post-like', 'post_like'); wp_enqueue_script('like_post', get_template_directory_uri().'/js/post-like.js', array('jquery'), '1.0', 1 ); wp_localize_script('like_post', 'ajax_var', array( 'url' =&gt; admin_url('admin-ajax.php'), 'nonce' =&gt; wp_create_nonce('ajax-nonce') )); function post_like() { $nonce = $_POST['nonce']; if ( ! wp_verify_nonce( $nonce, 'ajax-nonce' ) ) die ( 'Busted!'); if(isset($_POST['post_like'])) { $ip = $_SERVER['REMOTE_ADDR']; $post_id = $_POST['post_id']; $meta_IP = get_post_meta($post_id, "voted_IP"); $voted_IP = $meta_IP[0]; if(!is_array($voted_IP)) $voted_IP = array(); $meta_count = get_post_meta($post_id, "votes_count", true); if(!hasAlreadyVoted($post_id)) { $voted_IP[$ip] = time(); update_post_meta($post_id, "voted_IP", $voted_IP); update_post_meta($post_id, "votes_count", ++$meta_count); echo $meta_count; } else echo "already"; } exit; } function hasAlreadyVoted($post_id) { global $timebeforerevote; $meta_IP = get_post_meta($post_id, "voted_IP"); $voted_IP = $meta_IP[0]; if(!is_array($voted_IP)) $voted_IP = array(); $ip = $_SERVER['REMOTE_ADDR']; if(in_array($ip, array_keys($voted_IP))) { $time = $voted_IP[$ip]; $now = time(); if(round(($now - $time) / 60) &gt; $timebeforerevote) return false; return true; } return false; } function getPostLikeLink($post_id) { $themename = "twentyeleven"; $vote_count = get_post_meta($post_id, "votes_count", true); $output = '&lt;p class="post-like"&gt;'; if ($vote_count == 0) $output .= '&lt;span class="count"&gt;0&lt;span class="glosow"&gt;&lt;br&gt;głosów w rankingu&lt;/span&gt;&lt;/span&gt;'; else $output .= '&lt;span class="count"&gt;'.$vote_count.'&lt;span class="glosow"&gt;&lt;br&gt;głosów w rankingu&lt;/span&gt;&lt;/span&gt;'; if(hasAlreadyVoted($post_id)) $output .= '&lt;span title="Już głosowałeś" class="qtip alreadyvoted"&gt;&lt;/span&gt;'; else $output .= '&lt;a href="#" data-post_id="'.$post_id.'"&gt; &lt;span title="'.__('Głosuj', $themename).'"class="qtip like"&gt;&lt;/span&gt;&lt;/a&gt;'; $output .= '&lt;/p&gt;'; return $output; } </code></pre> <p>Heres code for query that finds if user already voted but problem is that after $timebeforerevote IP value stays in meta field so i can't use it. I have no more ideas for now...</p> <pre><code>$ip = $_SERVER['REMOTE_ADDR']; $query = new WP_Query( array( 'ignore_sticky_posts' =&gt; true, 'meta_key' =&gt; 'voted_IP', 'meta_value' =&gt; $ip ) ); if (0 !== $query-&gt;found_posts) { //do something } </code></pre>
