[LindaD]

How can I add <?php echo $_POST["mail"]; ?> as shown in script below without getting errors??

 

?php
// get posted data into local variables
$mail = Trim($_POST[mail]);
if (Trim($mail)=="")
{exit("Please enter your E-Mail.");
} else {
echo "The E-Mail You Entered Is <?php echo $_POST["mail"]; ?> !!";
}
?>

 

Thanks :-X

<?php
// get posted data into local variables
$mail = trim($_POST[mail]);
if (trim($mail)=="")
{exit("Please enter your E-Mail.");
} else {
echo "The E-Mail You Entered Is " . $_POST["mail"]. "!!";
}
?>

There are issues with your code Dathremar.

1. The trim function is being used on a variable that has already been trimmed

2. There is no need to use an else statement after an exit function. The script will terminate if the condition is not met.

 

Thirdly you code should check for a valid email address not just if the field is empty.

<?php
// get posted data into local variables
$mail = trim($_POST['mail']);
if(!eregi("^[^@]{1,64}@[^@]{1,255}$", $mail)) {
exit("Please enter a valid E-Mail address.");
}
echo "The E-Mail You Entered Is ".$mail;
?>

You are right, sorry. Didn't pay attention to that, I just copied his coded and change the part for echo of the variable.

Was in a hurry and i neglected the code itself :S

Hi Neil, thanks for the sample help.. what I'm trying to do is make firstname, lastname, mail, and pass required fields then when form submitted it creates a link like this: www.site.com/index.php?firstname=xxx&lastname=xxx&mail=xxx&pass=xxxx 'click here to continue'... if any of the fields left blank it says go back and fill in all fields.

 

Thanks

Why would you create a url string that contains all of the input data?

This would be easily open to abuse. If you want the data to remain persistent then either make the click to continue button a form submit, passing the user data into the form as hidden fields, or once the data has been validated then store it in session variables.
