Limit number of characters in textfields

Hi,
I want to limit the number of characters the user can enter in the textarea.
An alternative solution would be a character-counter below the textfield.
Any ideas to realize that?
Thanks.

You can use javascript to achieve this ... create a file in the "hooks" folder, naming it "tablename-dv.js" (where tablename is the name of the concerned table) and add code similar to this in it:
Code: Select all
jQuery(function(){
jQuery('#fieldname').attr('maxlength', 40);
});
(where fieldname is the name of the concerned field). Change 40 to the desired limit.

Thanks Ahmad, that works fine!
But realize that "maxlenght" doesn't work in IE9/8.
Spent a lot of time to find that out.
Installed IE11 - thats okay (FF also).
My next try: install a character counter below the textfield I want to be limited/counted.
Is this also possible by using the hook folder, or only by adding code directly in the table.php?

No it can be added using the same hook file using javascript ... you can find through Google lots of examples on how to implement this ... for example:
