I'm trying make a form where me or user can insert data. Some parts are coming form data base like: Work name and work price. In input fields can insert work amount. In each input row have checkbox, if checkbox ar checked, that row will be seen in php.

<table class="table">



        <thead>

            <tr>

                <th scope="col">*</th>

                <th scope="col">Work name</th>

                <th scope="col">Quantity</th>

                <th scope="col">Price for unit</th>

                <th scope="col">Total price</th>

            </tr>

        </thead>



        <form method="POST" action="process/pdf.process.php">

        <tbody>

            <?php

            $works = ORM::for_table('work')->find_many();

            foreach($works as $work){

            ?>

                <tr id="<?php echo $work->id; ?>">

                    <td><input type="checkbox" name="useit[]" value="<?php echo $work->id; ?>"/></td>

                    <td><?php echo $work->name; ?></td>

                    <td><input type="text" placeholder="" class="amount"/> <?php echo $work->unit; ?></td>

                    <td class="work_price" data="<?php echo $work->price; ?>"><?php echo $work->price.'€/'.$work->unit; ?></td>

                    <td class="total_price">0€</td>



                    <input type="" name="work_id[]" value="<?php echo $work->id; ?>" />

                    <input type="hidden" name="work_name[]" value="<?php echo $work->name; ?>" />

                    <input type="hidden" name="amount[]" class="<?php echo $work->id; ?>_copy_amount" value="" />

                    <input type="hidden" name="unit[]" value="<?php echo $work->unit; ?>" />

                    <input type="hidden" name="unit_price[]" value="<?php echo $work->price; ?>€" />

                    <input type="hidden" name="unit_total[]" class="<?php echo $work->id; ?>_copy_total" value="" />



                </tr>



            <?php

            }

            ?>

        </tbody>

            <input type="submit" name="do_pdf" value="Pga jkāuztaisa ar jquery" />

        </form>



    </table>

Now, there is php, but how can i show only checked rows in while loop?

<?php



 $data = array();

 $work_id = array();

 $work_names = $_POST['work_name'];

 $amounts = $_POST['amount'];

 $units = $_POST['unit'];

 $units_prices = $_POST['unit_price'];

 $units_total = $_POST['unit_total'];





 if(isset($_POST['useit'])){

  $work_id = $_POST['useit'];





 }



 $data = array($work_id, $work_names, $amounts, $units, $units_prices, $units_total);



 echo '<pre>';

 echo htmlspecialchars(print_r($data, true));

 echo '</pre>';



 ?>

My Answer:
To show only the checked rows in the while loop, you can modify your PHP code as follows:

php




$data = array();

$work_id = array();

$work_names = $_POST['work_name'];

$amounts = $_POST['amount'];

$units = $_POST['unit'];

$units_prices = $_POST['unit_price'];

$units_total = $_POST['unit_total'];



if(isset($_POST['useit'])){

    $checked_work_ids = $_POST['useit'];



    foreach($checked_work_ids as $checked_work_id){

        $key = array_search($checked_work_id, $_POST['work_id']);

        $data[] = array(

            'work_id' => $_POST['work_id'][$key],

            'work_name' => $_POST['work_name'][$key],

            'amount' => $_POST['amount'][$key],

            'unit' => $_POST['unit'][$key],

            'unit_price' => $_POST['unit_price'][$key],

            'unit_total' => $_POST['unit_total'][$key]

        );

    }

}



echo '';

echo htmlspecialchars(print_r($data, true));

echo '
';



?>

This code will loop through the checked work IDs and retrieve the corresponding data for those IDs from the POST variables. It will then store this data in the `$data` array, which you can use to display only the checked rows in your while loop.
