!=submit

[Anon]

I have a form that posts to $php_self how can I have php_self know if submit it pressed and if submit is pressed I want it to be e-mailed and if it is not clicked (like it should be when the page loads) it dosen't do anything

wow... have you considered using periods? :-)

okay, as far as I understand: you want a PHP to submit to itself, and the second time it is loaded, you want to email something.

Do this: print a form with a hidden variable called "submitted_once" with a value of "yes".

In your PHP, evaluate this value to find out what to do:

if(isset($_GET['submitted_once'])) {
// email
}
else {
// print your page with the form, hidden var, and submit button
}

i would suggest the code looks like this
<?
if($submit)
{
//do whatever you wish

}
else
{
?>
<form method="post" action="<? $php_self(); ?>">
<input type=button name=submit value="Submit"></form>

<?
}
?>

the variable $submit refers to the button name value. This will definately work. Happy experimenting

maybe I could just use semi-colons; That would be a good way to end a statement;

A simple way to do that is to check if the submit variable was set. Add a simple if statement to the top of the script :

<?

if (isset($submit)) {
  mail(); }

?>

I would advise against using $submit because $_POST['submit'] is the "better" (more secure) way. Plus from what I read in the latest docs of the PHP distrib, they are deprecating register_globals for security reasons :-)
