Validate Textarea to accept only characters no special symbols or numbers.

[saravanataee]

Dear all,
Greetings,
I have been scratching my mind for couple of times to know how could i restrict a textarea to only accept character's A-Z. No special symbols like @#!| and numbers are allowed. When i give them it should be throw me an error message.

I tried few jquery implementations. But nothing works for me as i m not aware how to apply them.

Can some one help on how to acheive this.

Would be great.!

Thanks!

<textarea pattern="^[a-zA-Z]*$"> should do it in browsers that support HTML 5. To add support for that to other browsers see http://javascriptexample.net/domform12.php

HTML5 sure is neat.
But you still cannot trust it. That assumes that an HTML form is used and obeys the pattern. Its pretty much the same with a preg_match though.

PHP Code:

$p = '/^[a-z]*$/i';
if (preg_match($p, $content))
{
    print 'thats good.';
} 


Where $content is the string.
You can also use ctype_alpha which is also just a-z case insensitive.
