Checking data on submit.

MBK

I need to write a script so that when a user clicks on submit the form doesn't post data to another form or even move onto another window, but will just update a database.

How do I do this?
Will I just write a function and then use the post method to post to the function??

Someone pls help me!!

how bout $PHP_SELF, so that it send the data to itself, and then the update can begin

How would I do that, I have tried setting the form action to php_self, but then what do I need?

I presume I will need something after the script, like an if statement or something like that?

Can someone pls help, this is driving me mad!!! 🙂

right, after the submition, you can use an if statement to test, if one form is sent

if($HTTP_GET_VARS['submit']=="submit"){
//update
//header
}
else {
// print the form again
}

OK,
I have the following script - sorry bout this, not quite getting there yet.

require("testing.php");
show_form();  //displays original reg form with user data.
echo"<html><form action=$PHP_SELF>
<input type=submit name=submit></form></html>";

if ($HTTP_GET_VARS['submit']=="submit"){
echo"<html><script>
alert(\"testing\")
</script></html>";
}

I want to make sure this works by just printing an alert message or just echoing a message to the screen before I start messing with my db.

Can you tell me where I am going wrong please? and if poss how to rectify it?

Thanks for your help.

Ignore my last post, I appear to have got it working,
I didn't assign a value to my submit button, so when it was checking if submit=='submit' it didn't!

I have sorted it out now, thanks very much for your help bernouli!
