Blank input fields

[LOUDMOUTH]

How can I block blank entries from this input box

 

<input type='text' name='name' maxlength='15' value='$user_class->username'>

 

<input type='submit' name='submit' value='Save Preferences'>

What do you mean by block? You can check against empty.

Yeah I wanted to keep people from pressing the Submit button and changing the info to blank in the DB thank you

Within your php file that processes the information do something like..

 

if(!empty($_POST['name']))
{
     //Update the DB
}
else
{
     echo 'You didn\'t enter a name.';
}

Use JavaScript.

Use JavaScript.

Yea, but technically he said "AND changing the info to black in the DB". So if you use server-side validation they're not submitting and updating the DB

Of course you have to do server-side validation in case JavaScript is turned off.
