Help adding confirmation of email '@' symbol to php script

[leet8845]

Hi,

 

I need some code to validate an email address sent on my form.

 

Does anyone know if its possible to add anything to exsiting code below to do this.

 

I'm mainly bothered that the email has a '@' symbol, nothing more complex really.

 

Here's my code which works fine at the mo:

 

<?php 

// Getformdataandcreateemail 
$Email2="mail@mywebsite.co.uk"; 
$email=$_POST['Email']; 
$name=stripslashes($_POST['Name']); 
$subject=stripslashes($_POST['Subject']); 
$messagecont=stripslashes($_POST['Message']); 
$message= 
<<<EOD 
-------------------------------- 
Enquiry from your website 
-------------------------------- 

Name: $name 
Subject: $subject 
EmailAddress: $email 
Message: $messagecont 

-------------------------------- 
End of Message 
-------------------------------- 
EOD; 

//Sendemail 
@mail($Email2,$subject,$message, "From:$Email2"); 
header("Location:thankyou.html"); 


?>

$email = "me@hotmail.com";
if (preg_match('/\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i', $email))
{
echo "email valid";
}

 

 

 

Better one (RFC 2822 standard)

$email = "me@hotmail.com";
if(preg_match('/\A(?:^[a-z0-9!#$%&\'*+\/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&\'*+\/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?$)\Z/i', $email ))
{
echo "email valid";
}

Hey thanks for that, just a couple of Q's: Any clues where I paste this into my code?, also do i change the email address?

 

Again thanks

[MadTechie]

replace

$email=$_POST['Email']; 

 

with

 

$email = $_POST['Email'];
if(preg_match('/\A(?:^[a-z0-9!#$%&\'*+\/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&\'*+\/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?$)\Z/i', $email ))
{



echo "email valid";
}

Hi thanks for that but its still not working, have I made a mistake?

 

<?php

// Getformdataandcreateemail
$Email2="mail@mywebsite.co.uk";
$email = $_POST['Email'];
if(preg_match('/\A(?:^[a-z0-9!#$%&\'*+\/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&\'*+\/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?$)\Z/i', $email ))
{
echo "email valid";
}
$name=stripslashes($_POST['Name']);
$subject=stripslashes($_POST['Subject']);
$messagecont=stripslashes($_POST['Message']);
$message=
<<<EOD
--------------------------------
Enquiry from your website
--------------------------------

Name: $name
Subject: $subject
EmailAddress: $email
Message: $messagecont

--------------------------------
End of Message
--------------------------------
EOD;

//Sendemail
@mail($Email2,$subject,$message, "From:$Email2");
header("Location:thankyou.html");


?>

Try this.

 

<?php

// Getformdataandcreateemail
$FromEMail =  "mail@mywebsite.co.uk";
$ToEMail=$_POST['Email'];

if(!preg_match('/\A(?:^[a-z0-9!#$%&\'*+\/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&\'*+\/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?$)\Z/i', $ToEMail))
{
die ("$ToEMail in an invalid email");
}
$name=stripslashes($_POST['Name']);
$subject=stripslashes($_POST['Subject']);
$messagecont=stripslashes($_POST['Message']);
$message=
<<<EOD
--------------------------------
Enquiry from your website
--------------------------------

Name: $name
Subject: $subject
EmailAddress: $email
Message: $messagecont

--------------------------------
End of Message
--------------------------------
EOD;

//Sendemail
@mail($ToEMail,$subject,$message, "From:$FromEMail");
header("Location:thankyou.html");
