PHP: Two buttons to submit - php

Question

I've been trying to submit two buttons, one to delete and one to edit/add. But I can't seem to get it right.
HTML:
<!-- Edit/Delete Account Form -->
<form method="get" action="edit.php" onsubmit="setTimeout('location.reload()');">
<div id="edit-form" class="modal hide fade">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h4><?php _e('Edit/Delete Account'); ?></h4>
</div>
<div class="modal-body">
<div id="message"></div>
<div class="control">
<div id="edit-account-form">
<table id="add-account" class="table">
<tbody>
<tr>
<td valign="middle">
Account Number
</td>
<td>
<input type="hidden" id="editid" name="editid" value=""/>
<input type="text" id="number" name="number" value="Enter Some text here "/>
</td>
</tr>
<tr>
<td>
Account Description
</td>
<td>
<input type="text" id="description" name="description" value="Enter Some text here "/>
</td>
</tr>
<tr>
<td>
Level 01
</td>
<td>
<input type="text" id="level01" name="level01" value="Enter Some text here "/>
</td>
</tr>
<tr>
<td>
Level 02
</td>
<td>
<input type="text" id="level02" name="level02" value="Enter Some text here "/>
</td>
</tr>
<tr>
<td>
Level 03
</td>
<td>
<input type="text" id="level03" name="level03" value="Enter Some text here "/>
</td>
</tr>
<tr>
<td>
Level 04
</td>
<td>
<input type="text" id="level04" name="level04" value="Enter Some text here "/>
</td>
</tr>
<tr>
<td>

</td>
<td>
<input type="text" name="account" value="Enter Some text here "/>
</td>
</tr>
<tr>
<td>
Allow General Journals
</td>
<td>
<select>
<option selected disabled>Select</option>
<option>Yes</option>
<option>No</option>
</select>
</td>
</tr>
<tr>
<td>

<td>
<select>Select</select>

</tr>
<tr>
<td>

<td>
<select>Select</select>

</tr>
<tr>
<td>

<td>
<select>Select</select>
</td>
</tr>
</tbody>
</table>
</div>
</div>
</div>
<div class="modal-footer">
<button type="submit" data-complete-text="<?php _e('Done'); ?>" name="add" class="btn btn-primary pull-right"><?php _e('Submit'); ?></button>
<p class="pull-left"><button type="submit" name="delete" class="btn btn-primary pull-right"><?php _e('Delete'); ?></button></p>
</div>
</div>
</form>
PHP:
<?php
//Account Details
$number = $_GET['number'];
$description = $_GET['description'];
$level01 = $_GET['level01'];
$level02 = $_GET['level02'];
$level03 = $_GET['level03'];
$level04 = $_GET['level04'];
$id = $_GET['editid'];
$dbc = mysqli_connect('localhost', 'root', 'root', 'accounting') or die('Connection error!');
if(isset($_POST['delete'])) {
$check = "DELETE FROM accountSlave WHERE `id` = '$id' ";
mysqli_query($dbc, $check) or die('Database error, delete account!');
}
if(isset($_POST['add'])) {
//$check = "DELETE FROM accountSlave WHERE `id` = '$id' ";
$check = "UPDATE accountSlave SET `accountNumber` = '$number', `accountDescription` = '$description', `accountLevel1` = '$level01', `accountLevel2` = '$level02', `accountLevel3` = '$level03', `accountLevel4` = '$level04' WHERE `id` = '$id'";
mysqli_query($dbc, $check) or die('Database error, add account!');
}
header('location:master-accounts.php');
?>
It works when I have one query. I've tried one query to add and to delete and it worked. But I need to submit a delete if delete button clicked and vice versa.
I followed this post to try get it right multiple buttons on a form
Any help or suggestions will be appreciated!

Answer 1

You need to use $_GET instead of $_POST. It should be like
if(isset($_GET['delete'])) {
and
if(isset($_GET['add'])) {
Because your form submit method is GET not the POST

Answer 2

You have to check which button is pressed and according to that do your operation.
Also you have to use $_GET not $_POST because your form method is GET.
if(isset($_GET['add'])) {
// code for add
} elseif(isset($_GET['delete'])) {
// code for delete
}
