[SOLVED] Email Validation

GrizzlyBear · July 9, 2008

Hi

I have tried to find some script to validate my mailer form, but ones i have found just don't seem work. Could anyone suggest a place I can find some good script that validates text field for email and telephone numbers. I have placed the php code below.

Would i put the code in the PHP file called sendmail.php, or the html form page called contact.html?

Thanks

<?php

$to = 'test@domain.co.za';

$email = $_POST['email'];

$name = $_POST['name'];

$cellphone = $_POST['cellphone'];

$company = $_POST['company'];

$position = $_POST['position'];

$enquiry = $_POST['enquiry-type'];

$message = <<<MESSAGE

<html>

<head>

<title>Contact Form</title>

</head>

<body>

<tr>

<td align="center" bgcolor="#999999" colspan="2"><strong>CONTACT FORM</strong></td>

</tr>

<tr>

</tr>

<tr>

<td bgcolor="#999999" colspan="2"><strong>$enquiry</strong></td>

<td bgcolor="#cccccc" width="300">$company</td>

</tr>

<tr>

<td bgcolor="#999999" width="150">Position</td>

<td bgcolor="#cccccc" width="300">$position</td>

</tr>

</table>

</body>

</html>

MESSAGE;

$subject = 'CONTACT FORM';

$headers = 'MIME-Version: 1.0' . "\r\n";

$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

$headers .= 'From: ' . $email;

mail($to, $subject, $message, $headers);

header('Location: http://www.yellowwoodestates.co.za/confirmed.html');

?>

yes in the sendmail.php file

http://www.tectite.com/ is often used for form validation

Thanks bendude!

I found this script, and incorporated it in my code. I have placed the entire code below as it is not working, and perhaps someone could help me out as to what im doing wrong...

Thanks

<?php

if(isset($_POST['sumbit'])){

$to = 'info@domain.co.za';

$email = $_POST['email'];

$name = $_POST['name'];

$cellphone = $_POST['cellphone'];

$company = $_POST['company'];

$position = $_POST['position'];

$enquiry = $_POST['enquiry-type'];

Thanks Ben

I managed to find an email validation script that works, but im having a problem with the number now, I have found some script, but it's not working, I think the function is right, but I think my positioning of the script is incorrect.

Below i have attached both php and form script...

PHP SCRIPT

<?php

$to = 'cheryl@a-africa.co.za';

$email = $_POST['email'];

$name = $_POST['name'];

$cellphone = $_POST['cellphone'];

$company = $_POST['company'];

$position = $_POST['position'];

$enquiry = $_POST['enquiry-type'];

function check_email_address($email) {

// First, we check that there's one @ symbol, and that the lengths are right

if (!ereg("^[^@]{1,64}@[^@]{1,255}$", $email)) {

// Email invalid because wrong number of characters in one section, or wrong number of @ symbols.

return false;

} // Split it into sections to make life easier

$email_array = explode("@", $email);

$local_array = explode(".", $email_array[0]);

for ($i = 0; $i < sizeof($local_array); $i++) {

if (!ereg("^(([A-Za-z0-9!#$%&'*+/=?^_`{|}~-][A-Za-z0-9!#$%&'*+/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$", $local_array[$i])) {

return false;

}

if (!ereg("^\[?[0-9\.]+\]?$", $email_array[1])) { // Check if domain is IP. If not, it should be valid domain name

$domain_array = explode(".", $email_array[1]);

if (sizeof($domain_array) < 2) {

return false; // Not enough parts to domain

}

for ($i = 0; $i < sizeof($domain_array); $i++) {

if (!ereg("^(([A-Za-z0-9][A-Za-z0-9-]{0,61}[A-Za-z0-9])|([A-Za-z0-9]+))$", $domain_array[$i])) {

return false;

}

return true;

}

function check_phone_number($cellphone) {

$cellphone = preg_replace('/[^0-9]/', '', $cellphone);

if (preg_match('/^1?[0-9]{10}$/', $cellphone)) {

return false;

}

return true;

}

if (check_email_address($email) && check_phone_number($cellphone)) {

what do you mean by a problem with the number? I can not test the code for you until i get home but if you describe the problem a little more i may be able to help you now.

GrizzlyBear · July 10, 2008

Well this script below is suposed to validate the cell phone number or 10 characters. I need it to come up with an error if the number is more than 10 and less than 10 numbers.

function check_phone_number($cellphone) {

$cellphone = preg_replace('/[^0-9]/', '', $cellphone);

if (preg_match('/^1?[0-9]{10}$/', $cellphone)) {

return false;

}

return true;

}

Bendude14 · July 10, 2008

<?php function check_phone_number($cellphone) {

if(trim($cellphone) == 10) { return true;  }

else {  return false; }

}
?>

This will make sure that the phone number has to be 10 characters. The trim function removes any white spaces...

Sorry i can not do this for you using regular expressions but im sure someone else could if you ask

Wolphie · July 10, 2008

<?php function check_phone_number($cellphone) {

if(trim($cellphone) == 10) { return true;  }

else {  return false; }

}
?>

This wouldn't check to see if the phnone number is 10 characters, it would check to see if it was equal to 10.

if(strlen(trim($cellphone)) == 10) { return true; }

Bendude14 · July 10, 2008

yer your right... everything seems to be hard work today..

strlen

<?php function check_phone_number($cellphone) {

$cellphone_length = trim(strlen($cellphone));

if($cellphone_length) == 10) { return true;  }

else {  return false; }

}
?>

Thank YOU, thanks fantastic! I got another question, if i wanted my error messages to display on the form page instead of a new page, how would i do that? I wouldn't even know what search for to find that. So for example, my email error message would display Invalid next to the input box.

Thanks again hey

Wolphie · July 10, 2008

You would need to submit the form to itself, or use JavaScript and Ajax.

Simple normal example:

<?php
if(isset($_POST['submit'])) {
  if(empty($_POST['name'])) {
    print 'Please enter a name!';
  }
}
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
  <input type="text" name="name" />
  <input type="submit" name="submit" />
</form>

Bendude14 · July 10, 2008

Change this

<?php function check_phone_number($cellphone) {

$cellphone_length = trim(strlen($cellphone));

if($cellphone_length) == 10) { return true;  }

else {  return false; }

}
?>

to this


<?php
$pattern = '/^[0-9]{10,10}$/';
$cellphone = "0000000000";

#
if (preg_match($pattern,$cellphone)) { return true; }
#
else { return false; }

?>

The new code should only allow 10 numbers where as the old code would allow 10 characters meaning someone could have put letters in as there telephone number.

GrizzlyBear · July 10, 2008

Hey Ben i got this error msg:

Warning: preg_match() [function.preg-match]: Empty regular expression in /usr/www/users/yellowf/sendmail1.php on line 52

Line 52: if (preg_match($pattern,$cellphone)) { return true; }

Thanks Wolphie, so that means i can put the error messages within the form page?

Is there such a command that i can put in that php script within the form page to go to sendmail.php to actually send the form mailer?

Bendude14 · July 10, 2008

it shouldn't have done did you put it inside your function like so

<?php
function check_phone_number($cellphone) {
$pattern = '/^[0-9]{10,10}$/';
$cellphone = "00000d00000";//remove this in live version just for testing

#
if (preg_match($pattern,$cellphone)) { return true; }
#
else { return false; }

}


?>

As for sending the mail you can use the mail function just look here to learn how to do it then post back with any other problems
