[SOLVED] isset post question

[graham23s]

Hi Guys,

 

i have a button on a form just a basic one:

 

<input name="submit" class="button" type="submit" value="Submit">

 

i tried to do:

 

     if (isset($_POST['submit'])) {
     
     echo 'DO CODE HERE!!';
     include("includes/footer.php");
     exit;
     
     }
     

 

i dont want to actually do a form just execute the code once the submit button is pressed is that possible or do i need to do the <form  action , method etc> code?

 

thanks guys

The $_POST array doesn't receive the submit key and value unless it is sent to it using the POST method. There is no way for php to catch html events, (such as button presses) Javascript can, though. If you want to run php after a button is pressed, the button has to redirect to that php page, somehow.

you would need

 

<form action="code.php" method="post">
<!-- submit button here --!>
</form>

 

and have code.php with your second boxes code.

u can use isset() on another form element rather then the button, as its value is passed to the post superglobal only if the button is pressed. Usually people fill in data and just press enter which doesnt pass the button's value to post. Hope im clear with this lol.
