I created a function safe variable (preg_replace) so I can keep my form a little more secured. The function validateinput has the "safe" but when I process my contact form, I get this error. The form submits the info to my email but I don't know why i'm getting that error.
Warning: Missing argument 2 for validateInput(), called in D:\Hosting\9777689\html\process.php on line 122 and defined in D:\Hosting\9777689\html\process.php on line 108
Here is my php code
<?php
function displayRequired($fieldName) {
echo " \".$fieldName\"is required.<br />n";
}
function validateInput($data, $fieldName){
global $errorCount;
if (empty($data)){
displayRequired($fieldName);
++$errorCount;
$retval = "";
} else {
$retval = trim($data);
$retval = stripslashes($retval);
}
return ($retval);
}
$Name = validateInput(safe($_POST['name'], "First Name"));
$Email = validateInput(safe($_POST['email'], "Email"));
$Comments = validateInput(safe($_POST['comments'], "Comments"));
$Company = validateInput(safe($_POST['company'], "Company"));
$Position = validateInput(safe($_POST['position'], "Position"));
$Phone = safe($_POST['phone']);
if ($errorCount>0){
echo "Please re-enter the information below.<br />\n";
redisplayForm($Name, $Email, $Phone, $Company, $Position, $Comments);
}
else
{
$To = "";
$Subject = "";
$From = "";
$Message .= "Name: " . $Name . "\n";
$Message .= "Email: " . $Email. "\n\n";
$Message .= "Phone Number: " . $Phone . "\n\n\n";
$Message .= "The name of the company " . $Company . "\n\n\n\n";
$Message .= "The person company position: " . $Position . "\n\n\n\n\n";
$Message .= "Comments: " . $Comments . "\n\n\n\n\n\n\n";
$Headers = "From: ". $From . "<" . $To. ">\r\n";
$Headers .= "Reply-To: " . $Email . "\r\n";
$Headers .= "Return-path: ". $Email;
$result = mail($To, $Subject, $Message, $Headers);
if ($result)
$resultMsg = "You message was sucessfully sent.";
else
$resultMsg = "There was a problem sending your message.";
