I am trying to create two submit button in my form
<form id="form-input-wrapper" action='test.php'> //form items.. //form items.. <button class="btn btn-primary" type="submit" value="old">first button.</button> <button class="btn btn-primary" type="submit" value="new">second button</button> </form> My question is how to distinquish which button the user clicks in my test.php page?
You need to add the name attribute to your buttons
<button class="btn btn-primary" type="submit" name="old" value="old">first button.</button> <button class="btn btn-primary" type="submit" name="new" value="new">second button</button> The php code to use would look like:
if ($_SERVER['REQUEST_METHOD'] === 'POST') { //something posted if (isset($_POST['old'])) { //old } elseif (isset($_POST['new']){ //new } } related question: How can I tell which button was clicked in a PHP form submit?
Use button name tag and check them in php:
<button name="subject1" type="submit" value="HTML">HTML</button> <button name="subject2" type="submit" value="CSS">CSS</button> And in php:
<?php if ($_SERVER['REQUEST_METHOD'] === 'POST') { if ( isset($_POST['subject1']) ) { // first button is clicked } elseif ( isset($_POST['subject2']) ) { //second button is clicked } } ?> 
nameattribute.
