Notice: Undefined variable: email_content

I have a contact form that is working at the moment,i only get two notices:

Notice: Undefined variable: email_content Notice: Undefined variable: header

This is the code

// check if an error was found - if there was, send the user back to the form 
if (isset($error)) { 
$_POST['e'] = $error; 
} else {

// write the email content <-- HERE IS WHERE THE ERROR OCCURS
$email_content .= "Naam:" . htmlspecialchars($name, ENT_QUOTES) . "\n\n"; 
$email_content .= "Tel:" . htmlspecialchars($tel, ENT_QUOTES) . "\n\n"; 
$email_content .= "E-mail:" . htmlspecialchars($email_address, ENT_QUOTES) . "\n\n"; 
$email_content .= "Onderwerp:" . htmlspecialchars($onderwerp, ENT_QUOTES) . "\n\n"; 
$email_content .= "Bericht:" . htmlspecialchars($message, ENT_QUOTES) . "\n\n"; 


/*
$email_content .= "Naam:$name\n\n"; 
$email_content .= "Tel:$tel\n\n"; 
$email_content .= "E-mail:$email_address\n\n"; 
$email_content .= "Onderwerp:$onderwerp\n\n"; 
$email_content .= "Bericht:$message\n\n";
*/ 
$header .= 'From: www.UTI.nl';   <-- AND HERE IS ALSO WHERE THE ERROR OCCURS
// send the email 
mail ("robin2609@gmail.com", "Nieuw bericht van de UTI website", $email_content, $header );   <-- this is 

// send the user back to the form 
$_POST['s'] = 'Bedankt voor uw bericht.';

What am i missing? I hope you guys can help me.

Kind regards,

Solution

  • Because you are trying to append to an undeclared string in $email_content & $header.

    On your first lines of each variable change the .= to =
