Get the values of 2 HTML input tags having the same name using PHP

Answer 1

When you have repeated names, you have to give them array-style names:

When you do this, $_POST['id'], $_POST['latitude'], and $_POST['longitude'] will be arrays containing the values.

Your form processing code can then iterate over these:

for ($i = 0; $i < count($_POST['id']); $i++) {
  if (isset($_POST['latitude'][$i], $_POST['longitude'][$i])) { // Make sure both are filled in
    // Do stuff with this row of the form
  }
}
