I came across a situation I can not get around.

I need to update a MySQL database field where its display is a checkbox .

I'll try to exemplify:

A search brings up a series of records, where after I checkboxes and click the "Confirm Conference" button, all records listed on this page should be updated according to checkbox checked, that is, only the checkbox field will be updated. Follow the image showing the screen that already exists.

<html><body><divid="main" class="container-fluid">
    <div id="top" class="row" style="margin-top: 50px">
        <div class="col-sm-4">
            <h3>Conferência do Depósito</h3>
        </div>
    </div> <!-- /#top -->
    </br>

    <div id="conf_deposito" class="row">    
    <div class="table-responsive col-md-12">
        <table class="table table-striped table-bordered " width="100%" id="tabela_datatables">
            <thead>
                <tr>
                    <th>Conferir</th>
                    <th>Nome</th>
                    <th>Tombamento</th>
                    <th>Quantidade</th>
                </tr>
            </thead>

            <tbody>
            <?php
            //Verifica se já existem registros com a mesma data do sistema. Se não existir, executa a cópia da tabela.
            $sis_data = date("Y/m/d");
            $unic = "SELECT * FROM conf_material WHERE data = '$sis_data'";
            $unic = $pdo->query($unic);
            if($unic->rowCount() < 1) {

            //Ao carregar a página, executa uma cópia dos registros para conferência.
            $cop = "INSERT INTO conf_material  (nome, tombamento, quantidade, local) SELECT nome, tombamento, quantidade, local FROM lista_geral WHERE local = 'deposito'";
            $cop = $pdo->query($cop);

            //Atualiza o campo de data para o data do dia.
            $atualiza_data = "UPDATE conf_material SET data = '$sis_data' WHERE data = '0000-00-00'";
            $atualiza_data = $pdo->query($atualiza_data);
            }

            if(isset($_POST['nome']) && empty($_POST['nome']) == false) {
                $nome = addslashes($_POST['nome']);
                $tombamento = addslashes($_POST['tombamento']);
                $quantidade = addslashes($_POST['quantidade']);
                $conferir = addslashes($_POST['conferir']);

                $sql = "UPDATE conf_material SET conferir = '$check_confirm'";
                $pdo->query($sql);
            }

            $sql = "SELECT * FROM conf_material WHERE local = 'Deposito' AND data = '$sis_data'";
            $sql = $pdo->query($sql);
            if($sql->rowCount() > 0) {

                        <td><?php echo $conf_deposito['quantidade']; ?></td>

    </div>
</form>

        </tbody>
    </table>

<?php require "rodape.php"; ?>

</html>

Does anyone have any idea how I can do this?

Good afternoon, Leo Caracciolo ...

Sorry for the mess ... I'll try to explain better what I need:

I have a select that brings a series of records. Here, I need to apply a flag (number 1 in bd) and that in my head, the best way would be to use a checkbox field, so that when the user marks the checkbox and then clicks the " Confirm Conference ", only the chackbox field - of all records - would be updated at the same time (with 0 or 1, depending on whether the field was checked or not). I hope I explained it better ... Thanks for the help! I'm breaking my head here too, while I'm waiting!

Your script looks more like a puzzle with a set of seven errors! :)

Initial Considerations

The form tag should involve all fields to be submitted:

<form method="POST">
<table class="table table-striped table-bordered " width="100%" id="tabela_datatables">
............
............
</table>
</form>

No foreach ($sql -> fetchAll() as $conf_deposito) {

should look like this:

<tr>
  <td class="actions">
    <input type='checkbox' id="check_confirm" name="check_confirm[]" value="<?php echo $conf_deposito['id'] ?>" class='btn btn-success btn-xs' data- data-toggle="modal">
  </td>

In the name attribute, at the end of its name, you must place brackets, indicating that more than one value can be sent to the same field. On the server side, an array with these elements will be sent.
