I have built a plugin that displays a table using the WP_List_Table class. The table displays entries on which it's possible to apply a filter and some bulk actions.

The problem is that is that when I click on the "filter" button or "apply bulk action" button multiple times, the _wp_http_referer paramater is added to the URL and keeps being longer and longer each time I click on the button.

Eventually the URL is so long that I get a blank page in the browser with the following error message:

Request-URI Too Large
The requested URL's length exceeds the capacity limit for this server.

I think I have set up the filter and bulk action select menus properly inside a simple form tag:

form action method="get"

The sale problem seems to have been described here: How to stop _wpnonce and _wp_http_referer from appearing in URL and as I am facing the same issue I am wondering if someone would have any idea how to remove the _wp_http_referer paramater from the URL after clicking on my form action buttons.

As the last commenter on that Q suggested, you should probably check for actions, remove the query args and redirect. Something like:

$doaction = $wp_list_table->current_action();
if ( $doaction && isset( $_REQUEST['SOMEVAR'] ) ) {
    // do stuff
} elseif ( ! empty( $_GET['_wp_http_referer'] ) ) {
    wp_redirect( remove_query_arg( array( '_wp_http_referer', '_wpnonce' ), stripslashes( $_SERVER['REQUEST_URI'] ) ) );

Thank you diggy I will look into that direction. – Vincent Jan 11 '13 at 0:26

Let me help you! Overwrite the parent method display_tablenav of WP_List_Table class removing the wp_nonce_field execution.

 * Generates the table navigation above or bellow the table and removes the
 * _wp_http_referrer and _wpnonce because it generates a error about URL too large
 * @param string $which 
 * @return void
function display_tablenav( $which ) 
    <div class="tablenav <?php echo esc_attr( $which ); ?>">

        <div class="alignleft actions">
            <?php $this->bulk_actions(); ?>
        $this->extra_tablenav( $which );
        $this->pagination( $which );
        <br class="clear" />

Here is the code that does the trick:

public function strip_wp_http_referrer () {
    $current_url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

    if (strpos($current_url, '_wp_http_referer') !== false) {
        $new_url = remove_query_arg( array( '_wp_http_referer', '_wpnonce' ), stripslashes($current_url));
        wp_redirect ($new_url);

Give the following script in footer or any common js

setTimeout(function() { jQuery( "input[name*='_wp_http_referer']" ).remove(); }, 500);
