infinite voting

Sorry this is not a problem rather you are allowing to vote multiple times. Please use the plugin settings to set how many times a user can vote.

You can only dislike a post after the voting period has passed. Lets say you have set the voting period to 1 day and now just you have voted. Then after 1 day you can revote. If you want to dislike, then you can dislike then.

Thanks

thanks for the quick response but i need that when someone liked a post he can dislike it whenever he choose to. the user should cast only 1 vote, but can like and only after that he can unlike(if he wants to vote again he has to like or unlike the post first)

This is not possible with the way this plugin is coded.

ok thanks

With minor modifications it’s easy to prevent having more than one likes or dislikes per user:

In wti_like_post.php, add the following function:

function HasWtiAlreadyVotedValue($post_id, $ip = null) {
	global $wpdb;

	if (null == $ip) {
		$ip = $_SERVER['REMOTE_ADDR'];
	}

	$wti_like_count =   $wpdb->get_var("SELECT SUM(value) FROM {$wpdb->prefix}wti_like_post WHERE post_id = '$post_id' AND ip = '$ip' AND value >= 0 ");
	$wti_unlike_count = $wpdb->get_var("SELECT SUM(value) FROM {$wpdb->prefix}wti_like_post WHERE post_id = '$post_id' AND ip = '$ip' AND value <= 0 ");

	$wti_like_count = $wti_like_count + $wti_unlike_count;

	return $wti_like_count;
}

In wti_like_post_ajax.php, replace the $can_vote section starting on line 60 by:

if ($can_vote) {
			$current_user = wp_get_current_user();
			$user_id = (int)$current_user->ID;
			$voted_value = HasWtiAlreadyVotedValue($post_id, $ip);
			$query = "";

			if ($task == "like") {
				if ($has_already_voted) {
				    if ($voted_value<1) {
					    $query = "UPDATE {$wpdb->prefix}wti_like_post SET ";
					    $query .= "value = value + 1, ";
					    $query .= "date_time = '" . date('Y-m-d H:i:s') . "' ";
					    $query .= "WHERE post_id = '" . $post_id . "' AND ";
					    $query .= "ip = '$ip'";
					} else {$msg = __('You already voted Like.', 'wti-like-post'); } //  $voted_value E [-1,0,1]
				} else {
					$query = "INSERT INTO {$wpdb->prefix}wti_like_post SET ";
					$query .= "post_id = '" . $post_id . "', ";
					$query .= "value = '1', ";
					$query .= "date_time = '" . date('Y-m-d H:i:s') . "', ";
					$query .= "ip = '$ip'";
				}
			} else {
				if ($has_already_voted) {
				    if ($voted_value>-1) {
					  $query = "UPDATE {$wpdb->prefix}wti_like_post SET ";
					  $query .= "value = value - 1, ";
					  $query .= "date_time = '" . date('Y-m-d H:i:s') . "' ";
					  $query .= "WHERE post_id = '" . $post_id . "' AND ";
					  $query .= "ip = '$ip'";
					} else {$msg = __('You already voted Dislike.', 'wti-like-post'); } //  $voted_value E [-1,0,1]
				} else {
					$query = "INSERT INTO {$wpdb->prefix}wti_like_post SET ";
					$query .= "post_id = '" . $post_id . "', ";
					$query .= "value = '-1', ";
					$query .= "date_time = '" . date('Y-m-d H:i:s') . "', ";
					$query .= "ip = '$ip'";
				}
			}

			if ($query != "") {
			    $success = $wpdb->query($query);
			    if ($success) {
			    	$error = 0;
			    	$msg = get_option('wti_like_post_thank_message');
			    } else {
			    	$error = 1;
			    	$msg = __('Could not process your vote.', 'wti-like-post');
		        }
			}
		}

Just got the same issue. Is it fixed?
