Support » Plugin: Search Regex » [Plugin: Search Regex] Checkbox options seem to be quirky in WordPress

  • I can’t get the case-insensitive option to work. For one, the 3 extra checkboxes do not show until I check the “Regex” box AND also click Search. Why do I need to click Search for the 3 other options to appear? And do I need to check “Regex” if I just want to check “Case-insensitive”. It seems so, since the “Case-insensitive” option doesn’t appear unless “Regex” is checked. Then when I have the Regex and Case-insensitive options both showing and checked, and I click Search, it returns the error: “Invalid regular expression: Delimiter must not be alphanumeric or backslash”. I just have the word “cheeze” in the search box and nothing in the replace box. Do I need to surround “cheeze” with something? Anyone, please? TIA.

  • For anyone else who may be asking the same question, I found how to do case-insensitive searches in Regex. (But I still can’t get the case-insensitive checkbox option to work, so I’m not using it).

    To do case-insensitive searches, only check the “Regex” option, and enter your search like this:


    I’m using single-quotes as the delimiter, you can use other non-alphanumeric chars too. This will find “cheeze” with any case. The “i” at the end is the regex flag for case-insensitive. You can google regex delimiters, or regex case-insensitive for more info.
