I took your code and modified it to use HTML5 validation (and few
other changes). You can see the results at
<http://my-testbed.com/test1/form_validation.php>http://my-testbed.com/test1/form_validation.php
My code follows:
<?php
$fields =
array('first_name','last_name','department','title','email','phone');
$num_forms = 1;
$tmp = array();
$errors = array();
if (isset($_POST['submit'])) {
$requestor_email = $_POST['requestor_email'];
$num_forms = $_POST['num_forms'];
for ($i = 1;$i <= $num_forms; ++$i) {
foreach ($fields as $fld) {
if ($_POST[$fld][$i] == '') {
$errors[] = ucwords(str_replace('_','
',$fld)) . " for account $i can not be blank";
}
}
}
}
if (!empty($errors)) {
$tmp[] = "The following fields are in error:<br>";
$tmp[] = implode("<br>\n",$errors);
$tmp[] = "<br>";
}
$tmp[] = "<div style='text-align:center'>You will be creating
$num_forms accounts today.</div><br>";
$tmp[] = '<div style="text-align:center"><form
name="ldap_accounts" method="post" action="">';
$tmp[] = '<br /><br />';
for($counter = 1;$counter<=$num_forms;$counter++) {
$tmp[] = "Enter user: $counter<br />";
$tmp[] = "<label for='first_name_$counter'>First Name:</label><br/>";
$tmp[] = "<input type='text' required
id='first_name_$counter' name='first_name[$counter]'><br /><br />";
$tmp[] = "<label for='last_name_$counter'>Last Name:</label><br />";
$tmp[] = "<input type='text' required
id='last_name_$counter' name='last_name[$counter]' /><br /><br />";
$tmp[] = "<label for='department_$counter'>Department:</label><br/>";
$tmp[] = "<input type='text' required
id='department_$counter.' name='department[$counter]' /><br /><br />";
$tmp[] = "<label for='title_$counter'>Title:</label><br />";
$tmp[] = "<input type='text' required id'title_.$counter'
name='title[$counter]' /><br /><br />";
$tmp[] = "<label for='email_.$counter'>Email:</label><br />";
$tmp[] = "<input type='email' required id='email_.$counter'
name='email[$counter]' /><br /><br />";
$tmp[] = "<label for='phone_$counter'>Phone:</label><br />";
$tmp[] = "<input type='text' required id='phone_$counter'
name='phone[$counter]' /><br /><br />";
}
$tmp[] = "<input type='hidden' id='num_forms' name='num_forms'
value='$num_forms' /><br /><br />";
$tmp[] = "<input type='hidden' id='requestor_email'
name='requestor_email' value='$requestor_email' />";
$tmp[] = "<input type='submit' name='submit' value='Create Ticket' />";
$tmp[] = "</form></div>";
?>
<!DOCTYPE html>
<html>
<head>
<title>LDAP Form</title>
<body>
<?php echo implode("\n",$tmp) . "\n"; ?>
</body>
</html>
You will notice that I moved the code for the form to above the HTML
section. I believe that very little PHP should be interspersed with
the HTML -- it makes for cleaner code. You can use single quotes
around form attributes so you don't have to escape the double quotes.
The names in the form are now arrays. This makes your life much
easier when extracting the values later in PHP.
When you check the page in a HTML5 aware brower, you will see how the
validation is done.
