Mass delete unpopular Tags

Question

Mass delete unpopular Tags

I have 1000's of tags and I would like to simply delete all tags that aren't used more than X times... i.e. 5 times.

Does anyone know of a simple way to do this? Even straight SQL would totally ROCK!

Answer 1

$x = 5; // set this to any number
$sql = "SELECT `name` FROM `wp_terms`";
$result = mysql_query($sql);
$count = array();
while($row = mysql_fetch_assoc($result))
{
  $count[$name]++;
}
foreach($count as $key = $value)
{
  if($value < $x)
    {
      $sql2 = "DELETE FROM `wp_terms` WHERE `name` = '". $key ."'";
      $result2 = mysql_query($sql2);
    }
}

There's more efficient ways of doing it but this will do the job.

Edit: make a backup first. I'm not entirely sure that that table is exclusive to tags.
