I want to control the tab order on some forms, and thought I could use the crmReplace function (very handy tool) to accomplish that. So I have code in my template such as this:

Code: [Select]

{$form.first_name.html|crmReplace:tabindex:2}
But it's not working. The tabindex is not added to the html. Any idea why? Nothing jumps out at me in the function itself that would indicate why I can't use it to replace/add any attribute to the tag.

Brian - Checking the code for that "plugin" here - CRM/Core/Smarty/plugins/modifier.crmReplace.php - it looks like it ONLY can replace values for existing attributes - but it can't add attributes to an element (despite what the comment implies). I'm not a regular expressions expert - but based on this doc, preg_replace only modifies the subject string if it finds a match on the pattern (attribute in this case).

http://us2.php.net/preg_replace

It would be cool if you could use it to add an attribute if it doesn't exist. I guess it would need to do preg_match first, and then preg_replace or an insert before the $endOfElement depending on if it found something. Wanna give that a shot ?

Yeah, that's it. Well, I need to figure out a better way to insert the attribute if it doesn't yet exist, but for now, this gets the job done:

Code: [Select]

    $pattern = '/' . $attribute . '="([^"]+?)"/';
	
	if (preg_match( $pattern, $string )) {
    	return preg_replace( $pattern, $attribute . '="' . $value . '"', $string );
		}
	else {
		return preg_replace( '/name=/', $attribute . '="' . $value . '" name=', $string );
	}
}

I'll look for a better solution.
