This snippet is causing the file to throw a 500 erorr, and I cannot see why.

<head>    
<?php

        $link = mysql_connect('****', '***', '*****');
        $db_selected = mysql_select_db('***', $link);
        if (!$db_selected) {
            echo 'error';
        }
        $adchan = $_COOKIE['adtail'];
        $adarray = json_decode($adchan);
        if($adarray->{'subcat'} != 'main'){
                $sql = "SELECT term_id FROM wp_terms WHERE slug='$adarray->{'subcat'}'";
                $result = mysql_query($sql);
                    while($row = mysql_fetch_array($result))
                  {
                    $id = $row['term_id'];
                    $sql2 = "SELECT option_value FROM wp_10_options WHERE option_name='$id'";
                    $result2 = mysql_query($sql2);
                        while($row2 = mysql_fetch_array($result2))
                      {
                          echo "<meta http-equiv='Refresh' content='".$row2['option_value']."'>";
                      }

                }
        }
        else{


                $sql = "SELECT term_id FROM wp_terms WHERE slug='$adarray->{'cat'}'";
                $result = mysql_query($sql);
                    while($row = mysql_fetch_array($result))
                  {
                    $id = $row['term_id'];
                    $sql2 = "SELECT option_value FROM wp_options WHERE option_name='$id'";
                    $result2 = mysql_query($sql2);
                        while($row2 = mysql_fetch_array($result2))
                      {
                          echo "<meta http-equiv='Refresh' content='".$row2['option_value']."'>";
                      }

                }
        }
    ?>
</head>

Can anyone see why?

UPDATE

<?php
error_reporting(-1);

        $adchan = $_COOKIE['adtail'];
        $adarray = json_decode($adchan);
        var_dump($adarray);
        print $adarray['cat'];
        ?>

It runs fine until the the print, which is when I get the 500 error. the output is:

object(stdClass)#1 (4) { ["cat"]=> string(9) "lifestyle" ["subcat"]=> string(12) "arts-culture" ["page"]=> string(4) "main" ["zone"]=> string(22) "lifestyle/arts-culture" }

    I’m not sure. But, it may because mysql_fetch_array cascade. You put mysql_fetch_array inside another mysql_fetch_array.

    And assume it works, but it will give you bad performance.

    This may be better for you. (In the inside of if part)

                    $sql = "SELECT a.term_id,b.option_value FROM wp_terms a LEFT JOIN option_value b ON b.option_name=a.term_id WHERE a.slug='{$adarray->subcat}'";
                $result = mysql_query($sql);
                while($row = mysql_fetch_array($result))
                {
                    $id = $row['term_id'];
                    if(isset($row['option_value']))
                        echo "<meta http-equiv='Refresh' content='".$row['option_value']."'>";

                }
