Help with a Form...

Since I cannot see, in your code shown, where the <form> statement begins and ends, I visited the link you gave. There the <form> can be seen. Now this is going to be a long reply:

If you want to verify and cleanse all fields the user typed in, the easiest way to handle that is to start your script with a check whether the routine was called for the first time or due to a form submit. You can determine that by e.g. having a hidden field in your form such as with name 'submitted' and check the existence of that field in the $_POST array. If it is not present, the form was not submitted i.e. this is the first time your script was called. When field 'submitted' is in the $_POST array, it means that the form was submitted and you have to check the filled in fields.

So first you make it possible to determine if a form was submitted or not, by inserting the following hidden field statement right after the <form action=....> statement.

Code:

<input type="hidden" name="submitted" value="1" />

Then you check, at the start of your script, if the script was called the first time or as a result of a submit. At the start of your script you insert the following:
[php]
<?php
// check if form was submitted
if (isset($_POST['submitted'])) {
$errors=array() ;
// it was submitted so here you do your field checking
// let's do E-mail as an example
// verify (a) filled in, (b) that is is an email address
if (!isset($_POST['E-mailmai']) OR
!ereg ('(^[0-9a-zA-Z_\.-]{1,}@([0-9a-zA-Z_\-]{1,}\.)+[0-9a-zA-Z_\-]{2,}$)', $_POST['email']) )
// email address incorrect, add msg to error array
$errors[] = "Invalid email address";
else
// email address okay, cleanse and save it
$email = stip_tags(trim( $_POST['E-mail']));
//
// more checking and validation ....
//
// .......

// at the end of your checking, see if any errors are set
if ($errors)
// if so, display the $errors array
// do not exit so the form is re-displayed
}
else {
// there are no errrors, send the email and exit
//
// here is your email build and send code
//
exit;
}
} // End of submit check

// from here on the form is displayed (again)
<html>
etc......
[/php]
Still to be coded: the display of all previously filled in fields in the case where the form is re-displayed. You don't want your users to fill in every field again in case of an error.

Let's, again, take the email <input> field as an example. The statement that requests the input must be changed, so it displays the content of variable $email (the var in which the email addess was saved). Like this

Code:

<input name="E-mail" size="36" style="float: left" value="<? echo $email ?>"></td>

Good luck with your form.
