setting minimum characters for field

Anon

Hello all!

I have a field for password, How can I set a minimum and maximum for this field. I want min = 5, max=15.

Thanks for your help!

$len = strlen($pass);

if($len < 5)
print "password is too short";
if($len > 15)
print "password is too long";

For the max value, set the textbox attribute to MAXLENGTH = 15.

The min value presents another problem, since there is no attribute for this. Now you have to do some "validation." You can do this "client" side with javascript. Or you can do this server side with PHP (my prefered method, since scripting may be turned off by the user).

Basically, what you need to do is call a validation form when the user submits the current form (the one with the password text box on it). You can then enforce the rule for minimum size by checking the length of the string that was entered and taking the appropriate action, perhaps forcing the user to return to the previous form and enter the appropriate data.

PHP works great for this type of operation and it's easy (even fun) to do.

Hope that helps.

maximum is easy - use the MAXLENGTH attribute of the input tag as follows:

to my knowledge (which isn't massive with html) there is no equivalent in simple html for the minimum. So, you need to look at some simple form validation.
Have the form's action url point to a script which starts something like the following(where the 'name' attribute of the password input field is 'password_field'):

if ( strlen($password_field) < 5 )
{
die("password must contain at least five characters. Hit the back button on your browser to go back and change it");
}

A better solution (some say) would be to test it client-side with javascript, which would be faster. BUT, some people don't have javascript enabled browsers and some switch it off so php wins.

Between the three of us, that is :-)

It's interesting to me to see how three different posts all converge on the same solution.
