如何在两个不同的按钮上执行同一事件？

Question

I have this piece of code below, supposing it will display no request when no data in database and it will display the request with an accept and reject button when they is data in database. How should i write my code in order to make the accept and reject button perform some action?

<?php 

        $travelRequest = $user->userTravelRequest($userid);
        if(!$travelRequest){
            echo '<div class="requestbox">
                  <p> You have no request from others at the moment. </p>
                  </div>';
        }

        else {
            foreach($travelRequest as $request){

                echo '<div class= "requestbox">
                      <p>'. $request->trip_name.'</p>
                      <p>Organised by '.$request->username.'</p>';

        ?>

                      <form method="POST">
                      <div class = "AR-btn">
                      <input type="button" name="accept" value="Accept"/>
                      <input type="button" name="reject" value="Reject"/>
                      <p></p>
                      </div>
                      </form>
                      </div>

        <?php   

            }

        }
        ?>

Answer 1

Use type="submit" instead of type="button" , and give them the same name. Then they'll submit the form, and the script can test which button was used from the value of that parameter.

<input type="submit" name="action" value="Accept"/>
<input type="submit" name="action" value="Reject"/>

You then test this with:

if (isset($_POST['action'])) {
    if ($_POST['action'] == 'Accept') {
        // Add to database
    } elseif ($_POST['action'] == 'Reject') {
        // Delete from database
    }
}

Answer 2

Try this code :-

<?php
if (isset($_POST['accept']) && $_POST['accept'] == 'Accept' ) {
    // do what you want
     die("Accept is clicked");
} else if (isset($_POST['reject']) && $_POST['reject'] == 'Reject' ) {
    // do what you want
    die("Reject is clicked");
}
?>
<?php
        $travelRequest = $user->userTravelRequest($userid);
        if(!$travelRequest){
            echo '<div class="requestbox">
                  <p> You have no request from others at the moment. </p>
                  </div>';
        } else {

            foreach($travelRequest as $request){
                echo '<div class= "requestbox">
                      <p>'. $request->trip_name.'</p>
                      <p>Organised by '.$request->username.'</p>'; 

        ?>
              <form method="POST">
                  <div class = "AR-btn">
                      <input type="submit" name="accept" value="Accept"/>
                      <input type="submit" name="reject" value="Reject"/>
                  <p></p>
                  </div>
              </form>
          </div>
        <?php
            }
        }
?>
