<h2>RelatóriodeProtocolo</h2><br><formid="formBuscaProtocolo" name="" method="post" action="view/pgs/relatorios/exibiRelatorio.php" target="_blank">
    <fieldset>
        <div style="border-radius:5px;padding:10px;">
            <table class="" cellspacing='0' width='100%' border ='0'>
                <tr>
                    <td style="width: 20%">Setores:</td> 
                    <td>
                        <select style="width: 301px;" name="cadastro.cad_setor" id="cadastro.cad_setor">
                            <?php $listaDados = $Usuario->carregaSetores(); ?>
                        </select>
                    </td>
                    <td>Período:</td>
                    <td><input style="width: 296px; " name='cadastro.cad_setor' type='month'/></td>
                    <td><button id="" class="BlueButton" type="submit">Gerar Protocolo</button></td>
                </tr>
            </table>
        </div>
    </fieldset>
</form>

and this is the part that I want to appear in the post method, before the given data comes from the database.

<?php print_r($_POST);?>
             <div>
                <table width="100%" CELLSPACING="0" CELLPADDING="2" BORDER="1" class='tabelaProt'>
                                <thead>
                                        <tr>
                                             <th>Alguma Coisa</th>
                                             <th>Alguma Coisa</th>
                                             <th>Alguma Coisa</th>
                                             <th>Alguma Coisa</th>
                                        </tr>
                                </thead>
                        <tbody>         
  <?php

            //echo "</pre>"; print_r($_indoperacional); exit;
     foreach($exibiRelatorios as $Relatorios){
          echo '<tr>';
          echo '<td align=center>'.$Relatorios.'</td>';
          echo '<td align=center>'.$Relatorios.'</td>';
          echo '<td align=center>'.$Relatorios.'</td>';
          echo '<td align=center>'.$Relatorios.'</td>';

          echo '</tr>';

        //print_r($_parametros);
     }
     ?>
