Question

I need to replace an html code in multiple posts. This is the code I am using:

UPDATE wp_posts SET post_content = REPLACE(post_content, 'target="_top" class="text"') WHERE 'post_content'  = 'class="text"'

But I am getting an error:

#1064 – You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use
near ‘) WHERE ‘post_content’ = ‘class=”text”” at line 1

Is there any solution to make it work properly ?

Answer 1

You need three arguments for replace, and you will also need to use LIKE in your WHERE clause or you won’t get any matches. Finally you don’t want single quotes around post_content in the WHERE clause. Either use backticks or nothing.

UPDATE wp_posts
SET post_content = REPLACE(post_content, 'class="text"', 'target="_top" class="text"')
WHERE post_content LIKE '%class="text"%'
