批量删除不受欢迎的标签

Mass delete unpopular Tags

我有 1000 个标签，我想简单地删除所有使用次数不超过 X 次的标签......即 5 次.

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.

有谁知道一个简单的方法来做到这一点?即使是直接的 SQL 也会完全摇滚！

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

推荐答案

$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); } }

有更有效的方法可以做到这一点，但这会完成工作.

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

先备份.我不完全确定该表是否专供标签使用.

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