— regexp search and replace WordPress plugin

Posted on

I wrote a small plugin for WordPress, which can search for specified strings (as regular expressions) in posts and pages and replace them with something else.

Just take a look:

  1. I got the same bug as SecretAgent, using WordPress 2.7.1

    The solution was to rename the directory in the zip file from “replace” to “” and upload that.

    Now works excellently. Thanks!

    1. *Agent Six, thank you.*

      I believe Codex renamed that directory itself (removed dot) :-)

      So, now i’ve edited php files to reflect this modification.

      So, *now* the plugin directory is named “replace”, because i don’t know how to “ask” Codex to leave it as is (“”). Sorry for that.

      Thank you!

  2. i want to change the restriction EX: do changes only if user is logged with LEVEL 3 or more. Now the plugin just check if logged or not.
    Is it possible to add this as a new restriction?

    1. Mmm… I guess it’s possible, but i need some time…

      First of all, what the UI should be (it would be too bad to choose between “logged”, “logged with level 1″…). Probably, drop-down selection “Logged with level…” followed by drop-down selection with numeric levels?..

      Anyway, I need to RTFM :O)

      Anyway, thank you a lot :-)

  3. Hey,

    I was just using your plugin with WordPress 2.9, and I needed to take out the checks for get_magic_quotes_gpc(), so that it always calls stripslashes(), in order to get backslashes to work. Thought you should know. Let me know if you have any questions.


    1. Mmm… Sorry!-) Didn’t understand. Backslashes do work… You can backslash backslash if you need backslash… As usually…

      I’ve not tried with 2.9 thought.

      Please, what You’re tried to search and how You do specify a replace string?

      1. In WordPress 2.9, with magic_quotes_gpc Off, if I try to create a pattern like:


        then my pattern gets shown on the listing screen as:


        and works like that pattern, not the pattern I want. This makes it impossible to create some patterns. The fix I mentioned before causes everything to work properly on my WordPress.

        You can see my modified version of the plugin at


        1. Thank You, Xavid!
          Looks meaningful, now it seems i understand You .)
          I need to check on my 2.8, since i don’t fully understand this magic though.

          Thank You!-)

  4. I have the same problem with this plugin, but first thx for this good plugin… so if I replace something with a link like this


    the plugin automatically escape the ” with \” … the same ‘ -> \̈́’

    I also have “magic_quotes_gpc = Off” in the php.ini and I tested it! If I enable this feature it work fine.

    ; We strongly recommend you use the escaping mechanisms
    ; designed specifically for the database your using instead of relying on this
    ; feature. Also note, this feature has been deprecated as of PHP 5.3.0 and is
    ; scheduled for removal in PHP 6.

    1. Thank you, Lars!

      I believed i would “release” next “version” of this plugin with some new features, but now i guess i will just correct this and leave those features for future :-)

      Thank you, indeed!

  5. I recently restored a wordpress database contents to a new database. A side effect was the arrival of many  characters replacing ‘spaces’ in nearly all the posts.

    Your plugin has enable me to remove them on the blog. From your description of the plug-in I suspect they still exist in the database.

    My wish-list feature is to add a functionality to make this replacement in the database aswell :-)

    thank you very much – this plugin was easy to find and use

  6. Greetings,

    This plugin works great for most of the content on my site, but I run buddypress, and would like to use it with the buddypress activity stream. Any thoughts on how I could make this work?
