I have two submit buttons in a form. How do I determine which one was hit serverside?
Solution 1:
Give each input a different value and keep the same name:
<input type="submit" name="action" value="Update" />
<input type="submit" name="action" value="Delete" />
Then in the code check to see which was triggered:
if ($_POST['action'] == 'Update') {
//action for update here
} else if ($_POST['action'] == 'Delete') {
//action for delete
} else {
//invalid action!
}
The problem with that is you tie your logic to the user-visible text within the input.
Solution 2:
Give each one a unique name and check the $_POST for the existence of that input:
<input type="submit" name="update_button" value="Update" />
<input type="submit" name="delete_button" value="Delete" />
And in the code:
if (isset($_POST['update_button'])) {
//update action
} else if (isset($_POST['delete_button'])) {
//delete action
} else {
//no button pressed
}
