I have an error when I use such an expression : ^[a-zA-Z]{2,}$ with smartyvalidate (criteria ="isRegExp". It does not seem to like the curly braces. Can curlybraces be used with SmartyValidate

That is because they conflict with the template delimiters. The best solution is to create a custom validation criteria like criteria="twoPlusChars" And use that instead of putting the regex directly in the template. As a matter of fact, you should always use custom criteria instead of the supplied RegExp criteria function, that "feature" was added with little forethought, this isn't the right place to do regex.

You can do any of the following:

1) change your smarty delimiters to something other than { and }
2) use {ldelim} and {rdelim} in place of { and } respectively
3) use {capture assign=foo} around a {literal} block that contains your text

That said, in-template regex's are bad form. You are better off creating a custom plugin validator that hides the regex implementation from your template users.

EDIT: oops, cross-posted with Monte. At least we have the same advice

Guys, Thanks for such a quick reply. I like the idea of making my own custom validation criteria. I tried but for some reason, what ever I input in my form gets rejected by the validate I made. It goes like so:

function smarty_validate_criteria_isTwoPlusChars($value, $empty, &$params, &$formvars) {
if(strlen($value) == 0)
return $empty;

return preg_match('^[a-zA-Z]$', $value);
}

I neglected the {2,} for now as I can't get the basic work... What am I doing wrong?

Never mind!! I figured it out :

!^[a-zA-Z]{2,}$!

What is the purpose of the exclamation mark anyway(!)?
