 |
|
When it comes to regular expressions I'm a dunce.
I want to restrict one text field to:
a-z
A-Z
0-9
_ (underscore)
- (dash)
and space characters.
I thought the following would do the trick but its not playing ball.
| Code: |
$form->registerRule('alphanuma','regex','/^[a-zA-Z0-9:b-_]$/');
$form->addRule('title','Only the characters a-z, A-Z & 0-9 are valid','alphanuma');
|
Any pointers would be appreciated
Many thanks.

What doesn't work? Examples?
And what do you expect to catch with ':b-_'? The dash needs to be escaped, BTW. |
