Hi,

I have a form that needs to check if the fields were completed and if not it echos a list of the fields that the user missed...

ie:

Name: _________
Email: ______
Age: _________

If they missed their age and email for example, the page would display an error and state that they missed the following fields:

Email
Age

and ask them to complete the missing fields below.

I noticed a post earlier that talked about using JS for this, this is not an option we wish to explore, we can use the

if(empty($variable_name)){...some code...}

what we are asking for is the logic to put this into place and have some code snippet check if each/any field is empty and if not add it to the list of missing fileds as in the example above

Just had a thought - an array would be perfect here and i could just echo each element of the array on a new line

so how do i put each of the empty fields into an array, and then how do i get them out again?

also how do i make it so it runs only if there is at least 1 empty field, yet if none, it does not run???

Any ideas are appreciated, but code snippets are best!

Thnx

Try this:

<body>

<?php
$submit=@$HTTP_POST_VARS['submit'];
$name=@$HTTP_POST_VARS['name'];
$email=@$HTTP_POST_VARS['email'];
$age=@$HTTP_POST_VARS['age'];

if(@$submit!=""){
$varnames=array('name','email','age');
$vars=array($name,$email,$age);
for($i=0;$i<count($vars);$i++){
if($vars[$i]==""){
echo "<p>ERROR: Please fill in field: ".$varnames[$i]."</p>";
}
}
}
?>

<form name="whatever" action="testing.php" method="post">
Name: <input type="text" name="name" value="<?php echo @$name; ?>">
<br/>
Email: <input type="text" name="email" value="<?php echo @$email; ?>">
<br/>
Age: <input type="text" name="age" value="<?php echo @$age; ?>">
<br/>
<input type="submit" name="submit" value="Submit">
</form>

</body>

Hope that helps!

Why have you put an @ before HTTP_POST_VARS and $Submit?

Something like this
www.icwib.org/beta_1/
got to download RFPs and create a new user. it you miss something it sends you back to the login with all the variables in red that were missed. If this is what you need email me at ron@conveyorgroup.com I had to block the phpmailserver because it was to much mail.
