How would I do this?

[Dylan B]

I have a bunch of form fields that I want to check if they're empty.

I could have a bunch of

if (empty($_POST['field1'])
{
echo "it was empty";
} 

could I like loop through all my form and then echo "You didn't fill out $missingfeildname";

?

im not sure you can do that...I use these (heres an example):

// Check for a first name.
if (eregi ("^[[:alpha:].' -]{2,15}$", stripslashes(trim($_POST['first_name'])))) {
$fn = escape_data($_POST['first_name']);
} else {
$fn = FALSE;
echo '<p><font color="red" size="+1">Please enter your first name!</font></p>';
}

Just loop through each value in the post array. ^^

  foreach($_POST as $name => $value){
     if(empty($value)){
       // do code - $name is the name as in $_POST['name'] and $value is the value entered in the form
     }
  
  } 

Hope that helps!

Yeah, you guys are all right, but I thought it was like:

if (!$field1){
echo "Feild is empty";
}

Im not sure if that is right. but is it? :s.

First of all, use $_POST['field1'] instead of $field1

Second of all, that WOULD be right, but, you would have to place 10 of those of you had 10 form fields, looping through the $_POST array is easier in that sense..

The problem is you need different validation for each type of entry. A name you need to check if it consists of only letters, an e-mail adres you need to validate according to it's structure etc etc...

Just a thought. I always use the test in the form strlen(trim($_POST["name"])) == 0 for text fields just to make sure that a space hasn't been entered where text is required. This only works for text fields of course as Quaint says and, of course, you may need to use isset to check that something like a checkbox has been checked.
