Checking characters in a string

[brent123456]

I have a javascript function set up to check characters as they are being typed. I was wondering how I would check the $_POST[foo] variable to make sure that it is less then say 50 character on submit in case javascript is turned off?

Thanks

<?php

if (strlen($_POST['foo'] > 50)){
   echo "Foo is too long!";

} else {
   echo "Foo is a good length....continue.";
}

?>

if (stripslashes(trim($_POST['discription']) && (strlen($_POST['discription'] < 75)))) {
                $d = escape_data($_POST['discription']);
   print strlen($_POST['discription']) ;
                } else {

                        $d = false;
                        echo '<p><font color="red" size="+1">Please enter your Feedback!</font></p>';
        		}

 

This doesn't seem to be validating is there something wrong with my code? Even when $_POST['discription'] is more then 75 characters it is not going to the else option.

Try this:

 

<?php

$description = stripslashes(trim($_POST['discription']));

if (strlen($description) < 75) { //If description is LESS than 75 chars

$d = escape_data($description); //I'm assuming escape_data() is a function you wrote?
print strlen($description);

} else { //Do this if description is MORE than 75 chars

$d = false;
echo '<p><font color="red" size="+1">Please enter your Feedback!</font></p>';
}

?>
