Reynaldovb,

Thank you
Thank you
Thank you

To be suprised I am not sure why this isn't a default item within vB. The amount of work generated by users saying "my log in doesn't work" all because of spaces and symbols is incredible.

Do I put \- at then end to add the "-" symbol? I dont mind having that as well.

Yes, it would be something like this:

PHP Code:


		
			
if (preg_match('/[^a-zA-Z0-9\_\-]+/', $_POST['username']))

* clicks install *

I haven't had a problem with user names like >>..@---@..<< yet !!!

However, I don't want to have such problems!!!

Thank you. I'm going to test this out. And I only have 85 members, so I will email a few of them to notify them that an underscore has been added to their names. (I will add them manually)

Does anybody which part in CSS to modify the error message color. The error message color on my forum is so light, that it can barely be seen.

Thanks.

UPDATE..........

I found it. Page Background, Font Color

i've installed V3.0.6

following code in register.php

PHP Code:


		
			
    $errors = array();



    // check username does not contain semi-colons

    if (preg_match('/(?<!&#[0-9]{3}|&#[0-9]{4}|&#[0-9]{5});/', $_POST['username']))

    {

        //eval(print_standard_error('error_username_semicolon'));

        eval('$errors[10] = "' . fetch_phrase('username_semicolon', PHRASETYPEID_ERROR) . '";');

    }

Is that the same or what?

PHP Code:


		
			
if (preg_match('/[^a-zA-Z0-9\_\ \]+/', $_POST['username']))

Is this the correct code if I want to allow space in user names ?
I am using one :)

No, I think the correct way to do it would be something like this:

PHP Code:


		
			
if (preg_match('/[^a-zA-Z0-9\_\s]+/', $_POST['username']))

I would like to install this hack in vB 3.06. I would also like to allow spaces in usernames. Which of the above code would be correct to use in 3.06?

Thanks
