Question

I have a calculator form included in my sidebar, below a login form. When a user submits the login form, that action triggers the:

if ($_SERVER['REQUEST_METHOD'] == 'POST') {}

statement in my other form. I tried adding an:

if (isset($varOne)) {}

statement, using the:

$varOne = $_POST['varOne'];

from the calculator script, but that didn’t work either. The calculator script continues to run if the login form is submitted. How must we stop the madness?!

Answer 1

You can combine the two:

if ($_SERVER['REQUEST_METHOD'] === 'POST' && isset($_POST['varOne'])) {
  // calculator button was pressed
}

or:

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
  if (isset($_POST['varOne'])) {
    // calculator button was pressed
  } else {
    // probably a login post
  }
}
