How te check if a form is sent ?

[visitor]

I'm busy with a form which sends to itself. How do I check if the form has already been sent or if it's the first time the page is loaded ?

Visitor

[crusty_php]

see if variable $submit is set

if (isset($submit)){
//form submitted
}else{
//form not submitted
}

[visitor]

what is the variable linked to ?

[[deleted]]

to a field in your form ofcourse 🙂

How can you check wether any data was submitted? by checking wether any data was submitted. 🙂

<?
if ($submit) // the form has been submitted
{
echo 'you have submitted the fotm!';
}
else
{
echo '<FORM method="post" action="'.$PHP_SELF.'">
<INPUT type="hidden" name="submit" value="yes">

INSERT YOUR FORM STUFF HERE

<INPUT type="submit" value="send this form now">
</FORM>';
}

if you do that it'll say
undefined variable submit

true. If you turn off error messages, then it won't.

if you want to just see if the user has posted to the currect page, you could use this:

if (strtolower($HTTP_SERVER_VARS["REQUEST_METHOD"]) == "post")
{
//Form has been submitted
}
else
{
//Print form stuff
}
