  • Define complex Regular Expression

    Hi,

    I want to create a regular expression for the username field on registration, that disallow users from using certain words, and some characters limitations.

    By seaching the forums I have found some expressions that could help me, but I'm not sure about the right way to combine it together.

    Code:
    (?!^term1$)^[a-zA-Z0-9 _-]+$
    I think, this should disallow from people to use the word "term1" and to force them to use this only characters.
    If then, I want to add here also "term2" as a forbidden string.

    Can you organize it for me plz?

    Thank you.

    Don't try using regex to disallow usernames. This is already available in your AdminCP.

    AdminCP > vBulletin Options > vBulletin Options > User Registration Options > Illegal User Names

      Nice, I guess that you understood what am I planning, cause you have replyed on my second question.
      But as like there, you are trying to avert me from a true solution by compromise and using common options on my system.

      So, like you have already indicated, I want to use the regex to disallow usernames. The option that available in AdminCP is useless for my needs, as I explained here.
      Can you, or anybody else help and tell me how to do that?

      Thanks anyway.

        This requires custom coding which we cannot officially support. Try asking for help with this at the vB Mod site: www.vbulletin.org

          Give me a favor! Don't rubbish me with that sentence.
          I have not asked to code some custom code in the system!

          I asked only for some help with that regex thing, for use in the username field on registration at AdminCP.

          This regex works alone:
          Code:
          (?!^[COLOR=Red]term1[/COLOR]$)^.+$
          This regex works alone too:
          Code:
          (?!^[COLOR=Red]term2[/COLOR]$)^.+$
          And this regex, also works alone:
          Code:
          ^[[COLOR=Red]a-zA-Z0-9 _-[/COLOR]]+$
          I want to know how to connect all these three together. That's all!

            Regex is custom coding.

              Even when it's on a regular field at AdminCP?
              I don't understand why it's different from any other functions there.


              Anyway,
              sorry for bothering you.
