Mail efter tilmelding
Hejsa...Jeg vil gerne have at der bliver sendt en mail til den der tilmelder sig maillisten, er der en der hurtigt, MEGET hurtigt kan fikse det for mig? Hvor jeg selvf. selv bestemmer emne, besked og fra... TAK , det er enormt vigtigt.
Her er koden;
<?
/*
*/
// to avoid showning errors (change to 1 to show them). For security
error_reporting(0);
// if info is posted, show the form and die
// the form is in the bottom of the page
if (!$_POST){print_form();die();}
// when info is posted you will be here
?>
