Unable to delete user from checkbox in PHP - php

Question

i am trying to delete some rows but i dont know where i am mistaking please check this below code and suggest my error with solution:
if(isset($_GET['delete']) && $_GET['delete']=="true")
{
$checkbox = $_POST['checkbox'];
for($i=0;$i<count($checkbox);$i++)
{
echo $checkbox[$i]; // here i am going to write delete query
}
}
Now my HTML code for that. I have created a table for users.
it looks something like this in HTML
<table id="sample_2">
<thead>
<tr>
<th style="width:8px;"><input type="checkbox" class="group-checkable" data-set="#sample_2 .checkboxes" /></th>
<th>Username</th>
<th>Full Name</th>
<th class="hidden-480">Email</th>
<th>Mobile</th>
<th>Activation Key</th>
<th class="hidden-480">Status</th>
</tr>
</thead>
<tbody>
<?php $user_details->all_user_details(); ?>
</tbody>
</table>
Now here is the function i am using. to create table rows. So check this out:
while ($row = $database->fetch_array($result_set)) {
$single_row ="<tr class=\"odd gradeX\">
<td><input type=\"checkbox\" name=\"checkbox[]\" class=\"checkboxes\" value=\"".$row["userid"]."\" /></td>
<td>".$row['username']."</td>
<td>".$row['fullname']."</td>
<td class=\"hidden-480\">".$row['email']."</td>
<td>".$row['mobile']."</td>
<td>".$row['user_activation_key']."</td>";
if($row['status']==1){
$single_row .= "<td><span class=\"label label-success\">Approved</span></td>";
} else{
$single_row .= "<td><span class=\"label label-danger\">Pending</span></td>"; }
$single_row .="</tr>";
echo $single_row;
}
any solution for this problem? I know i am making mistake somewhere in $_POST['checkbox'] while getting the value, Please suggest.
Thank you!

Answer 1

this is your first problem:
if(isset($_GET['delete']) && $_GET['delete']=="true")
{
$checkbox = $_POST['checkbox'];
for($i=0;$i<count($checkbox);$i++)
{
echo $checkbox[$i]; // here i am going to write delete query
}
}
please change it to this:
if (isset($_GET['delete']))
{
if ($_GET['delete']=="true") {
$checkbox = $_POST['checkbox'];
for($i=0;$i<count($checkbox);$i++)
{
echo $checkbox[$i]; // here i am going to write delete query
}
}
}
and also you forgot to leave a space between if and (
