PHP Filter on a Form

[dshaw]

I'm a very novice user with html and php. Website and php form is in place working correctly before i got here. We receive many blank forms or forms with only one field filled out from users that must sit there and click submit. Is there a way to force a pop up when not enough has been filled out. Or if easier block the form from being sent. Thanks in advance. P.S. A filter.txt file is already set up that has a list of bad words in it.

You can use strlen() to find out how many letters a string contains, if you don't want the user to be able to press the submit button if the input is not correct use javascript

Try this:

if (isset($GET['name']) and isset($GET['message'])
{
$message = $_GET['message'];
$filter = file_get_contents('filter.txt');

str_replace($filter,'[cabbage]', $message);

//Send form

}
else
{
echo "Sorry, you did not fill out all the fields, please try again";
}

I do realise that this will be hard to understand if you don`t know any PHP at all, but this a way to do it.
