Browsers ignoring "maxsize" attribute of input tag

[techiejp]

I'm finding a growing number of errors coming in from our server because some browser is explicitly ignoring the maxlength attribute and it violates a constraint on the database. Can someone give me an idea what browser does this and if there's a way around it? Thanks.

Don't know about the browser part of it but if the script is written in Perl you can add the following:

if (length($form_data) > 100) {
$form_data = substr($form_data,0,100); # Shortens the string to 100 characters.
}

Of course, replace $form_data with the proper variable from your script.

I recently noticed Netscape 4.77 ignoring maxsize while running on Windows 98 -- what a bummer, that is not some obscure browser!

Key_Master - Althougth I wouldn't want to cut parts of data off (makes for a very messy database), you have given me an alternative which might be useful. I hate having to make twice the work for myself making server side error catching. But, it would appear there isn't a better solution with the way browsers are going these days.

You could try using length() to catch the variables that are exceeding the maximum size and then return them back to properly fill in the form data.

if (length($form_data) > 100) {
Some action to redirect the visitor's browser back to resubmit the form field here
}
