フォームからデータベーステーブルに複数の行を挿入する

マネージャーが記入できるチェックリストフォームがあります。そして下部に、従業員が完了時にサインオフできる材料リストを入力します。材料の量は、20行以上にもなる可能性があります。以下は、それらが記入する行に含まれるものです。

        <tr><td><button type="button" class="addRow">Add Row</button></td></tr>
        <tr><th>WO# / Date <br/>(if added or changed after Revision 1)<th>Component Name and Number</th><th>Finish Sizes</th><th>Material</th><th>Total # Pieces</th><th>Work Order</th><th>Notes</th><th>Work Order</th><th>Notes</th><th>Work Order</th><th>Notes</th></tr>
        <tr>
            <td><input type="text" name='wo_num_and_date'/></td>
            <td><input type="text" name='comp_name_and_num'/></td>
            <td><input type="text" name='finish_sizes'/></td>
            <td><input type="text" name='material'/></td>
            <td><input type="text" name='total_num_pieces'/></td>
            <td><input type="text" name='workorder_num_one'/></td>
            <td><textarea rows="2" cols="12" name='notes_one'></textarea></td>
            <td><input type="text" name='workorder_num_two'/></td>
            <td><textarea rows="2" cols="12" name='notes_two'></textarea></td>
            <td><input type="text" name='workorder_num_three'/></td>
            <td><textarea rows="2" cols="12" name='notes_three'></textarea></td>
        </tr>

最初は1つの入力可能な行から始まり、次に行を追加できるjqueryがいくつかあります。

以下の挿入スクリプトは、フォームの最初の行のみを挿入しています。

if(isset($_POST['submit'])){
   $user = getuserinfo($loggedin_id);
   $posted_date = $_POST['posted_date'];
   $revision = $_POST['revision'];
   $per_wo_num = $_POST['per_wo_num'];
   $category = $_POST['category'];

   $wo_num_and_date = $_POST['wo_num_and_date'];
   $comp_name_and_num = $_POST['comp_name_and_num'];
   $finish_sizes = $_POST['finish_sizes'];
   $material = $_POST['material'];
   $total_num_pieces = $_POST['total_num_pieces'];
   $workorder_num_one = $_POST['workorder_num_one'];
   $notes_one = $_POST['notes_one'];
   $workorder_num_two = $_POST['workorder_num_two'];
   $notes_two = $_POST['notes_two'];
   $workorder_num_three = $_POST['workorder_num_three'];
   $notes_three = $_POST['notes_three'];


$sql = "INSERT INTO checklist_revision (job_num, user_id, revision_num, category, posted_date, per_workorder_number)
VALUES ($job_num,
        $loggedin_id,
        $revision,
        $category,
        STR_TO_DATE('$posted_date', '%Y-%m-%d'),
        $per_wo_num);";

 mysqli_query($dbc3, $sql);


$revision_id = mysqli_insert_id($dbc3);

$sql2 = "INSERT INTO checklist_component_stock (revision, job_num, category, posted_date, wo_num_and_date, comp_name_and_number, finish_sizes, material, total_num_pieces, workorder_num_one, notes_one, signoff_user_one, workorder_num_two, notes_two, signoff_user_two, workorder_num_three, notes_three, signoff_user_three)
VALUES ('$revision_id',
        '$job_num',
        '$category',
        STR_TO_DATE('$posted_date', '%Y-%m-%d'),
        '$wo_num_and_date',
        '$comp_name_and_num',
        '$finish_sizes',
        '$material',
        '$total_num_pieces',
        '$workorder_num_one',
        '$notes_one',
        NULL,
        '$workorder_num_two',
        '$notes_two',
        NULL,
        '$workorder_num_three',
        '$notes_three',
        NULL);";

 mysqli_query($dbc3, $sql2);

追加する行数に関係なく、最初の行だけでなくすべてをテーブルに挿入するようにするにはどうすればよいですか？
