Warning: array_key_exists() expects parameter 2 to be array

What happens when you add this code at line 225 of top-10.php

global $wpdb, $tptn_settings;
if ( empty( $wp ) ) {
global $wp;
}

I’m not add the code, I just replaced it.

function tptn_parse_request( $wp ) {
   	global $wpdb, $tptn_settings;
    if ( empty( $wp ) ) {
    global $wp;
    }

	$table_name = $wpdb->base_prefix . "top_ten";
	$top_ten_daily = $wpdb->base_prefix . "top_ten_daily";
	$str = '';

	if ( array_key_exists( 'top_ten_id', $wp->query_vars ) && array_key_exists( 'activate_counter', $wp->query_vars ) && $wp->query_vars['top_ten_id'] != '' ) {

		$id = intval( $wp->query_vars['top_ten_id'] );
		$blog_id = intval( $wp->query_vars['top_ten_blog_id'] );
		$activate_counter = intval( $wp->query_vars['activate_counter'] );

		if ( $id > 0 ) {

			if ( ( 1 == $activate_counter ) || ( 11 == $activate_counter ) ) {

				$tt = $wpdb->query( $wpdb->prepare( "INSERT INTO {$table_name} (postnumber, cntaccess, blog_id) VALUES('%d', '1', '%d') ON DUPLICATE KEY UPDATE cntaccess= cntaccess+1 ", $id, $blog_id ) );

				$str .= ( FALSE === $tt ) ? 'tte' : 'tt' . $tt;
			}

			if ( ( 10 == $activate_counter ) || ( 11 == $activate_counter ) ) {

				$current_date = gmdate( 'Y-m-d H', current_time( 'timestamp', 0 ) );

				$ttd = $wpdb->query( $wpdb->prepare( "INSERT INTO {$top_ten_daily} (postnumber, cntaccess, dp_date, blog_id) VALUES('%d', '1', '%s', '%d' ) ON DUPLICATE KEY UPDATE cntaccess= cntaccess+1 ", $id, $current_date, $blog_id ) );

				$str .= ( FALSE === $ttd ) ? ' ttde' : ' ttd' . $ttd;
			}
		}
		Header( "content-type: application/x-javascript" );
		echo '<!-- ' . $str . ' -->';

		//stop anything else from loading as it is not needed.
		exit;

	} elseif ( array_key_exists( 'top_ten_id', $wp->query_vars ) && array_key_exists( 'view_counter', $wp->query_vars ) && $wp->query_vars['top_ten_id'] != '' ) {

		$id = intval( $wp->query_vars['top_ten_id'] );

		if ( $id > 0 ) {

			$output = get_tptn_post_count( $id );

			Header( "content-type: application/x-javascript" );
			echo 'document.write("' . $output . '")';

			//stop anything else from loading as it is not needed.
			exit;
		}

	} else {
		return;
	}
}
add_action( 'wp', 'tptn_parse_request' );

Hi,

Could you please try changing the last line of your code i.e. the add_action to:

add_action( 'parse_request', 'tptn_parse_request' );

Could you please let me know if this removes the warning and also tracks the posts?

Hi,
It works for me, all the warning is gone and the plugin also tracks the posts.

thanks for your help.

Thank you for confirming. I’ll put this in as a fix for the next version.
