Get dynamic checkbox values

  • 772

I have several dynamic checkboxes and I need to know which ones have been clicked so that I can then send that data to the database. I have googled but the information that appears is about "fixed" checkboxes, if someone can help me I would greatly appreciate it. Here is the code of how I make the dynamic checkboxes

include "models/conexion.php";

$dep_mant_usuarios = $_POST['division'];
$sql_modulo = "SELECT idmodulos, idDivision, nombreModulo FROM modulos WHERE idDivision = '$dep_mant_usuarios' ORDER BY nombreModulo ASC";

$query_modulo = $pdo->prepare($sql_modulo);
$query_modulo->execute();
$result = $query_modulo->fetchAll();

$query_modulo = null;

 echo'<table class="tg">';
    echo'<tr>';
        echo'<th class="tg-xldj modulo">MÓDULOS</th>';
        echo'<th class="tg-c3ow rol">Ingresar</th>';
        echo'<th class="tg-c3ow rol">Modificar</th>';
        echo'<th class="tg-c3ow rol">Consultar</th>';
        echo'<th class="tg-c3ow rol">Imprimir</th>';
        echo'<th class="tg-c3ow rol">Exportar</th>';
    echo'</tr>';

    if (is_array($result)){
        foreach ($result as $row){
            $nom_modulo = $row['nombreModulo'];
            $id_modulo = $row['idmodulos'];

                echo '<tr>';
                    echo '<td class="tg-hmp3"><input name="" type="checkbox" value="'.$id_modulo.'"> '.$nom_modulo.'</td>';
                    echo '<td class="tg-0lax" ><center><input name="" value="" type="checkbox"></center></td>';
                    echo '<td class="tg-0lax" ><center><input name="" value="" type="checkbox"></center></td>';
                    echo '<td class="tg-0lax" ><center><input name="" value="" type="checkbox"></center></td>';
                    echo '<td class="tg-0lax" ><center><input name="" value="" type="checkbox"></center></td>';
                    echo '<td class="tg-0lax" ><center><input name="" value="" type="checkbox"></center></td>';
                echo '</tr>';
        }
    }

    echo'</table>';

    When you create your checkbox, add the value to the name attribute idModulo[]. So it will be an array that stores the values ​​of the checkboxes that are sent by POST

    echo '<td class="tg-hmp3"><input name="idModulo[]" type="checkbox" value="'.$id_modulo.'"> '.$nom_modulo.'</td>';

    you retrieve it from POST with

    $_POST['idModulo'];

    then in the code you use a for or a foreach to check them as any array
