复选框选中或未选中布尔php mysql

我想使这个表单与复选框获取值1或0，排序布尔，并在MySQL上更新它，但我还没有找到一种方法呢。也许你可以帮忙。我将发布表单和接收它的代码。我相信可能会有循环冲突，但我尝试了一切，无法让它工作。提前Tks。复选框选中或未选中布尔php mysql

形式

<form action="esconde_cat.php" method="post"> 
    <table width="300px" align="center" width="140" border="1"> 
     <tr> 
      <td></td> 
      <td width="200">Categoria</td> 
      <td width="100">Mostrar</td> 
     </tr> 
     <?php 
      include "conecta.php"; 
      include "verifica.php"; 

      $sql = "SELECT * FROM categorias ORDER BY ordem"; 
      $res = mysql_query($sql) or die (mysql_error()); 
      while ($linha=mysql_fetch_array($res)) { 
     ?> 
     <tr> 
      <td><input name="user[]" type="checkbox" value="true"/></td> 
      <td><?=$linha['1']; ?></td> 
      <td><?php if ($linha['3'] == TRUE){ echo 'SIM'; } else {echo 'NÃO'; } ?></td> 
      </td> 
     </tr> 

     <?php 
      } 
     ?> 
    </table> 
    <br/> 
    <table align="center"> 
     <tr> 
      <td> 
       <input type="submit" name="Delete" type="button" value="Alterar"> 
      </td> 
     </tr> 
    </table> 
</form>

如果复选框被任其发展，你会得到在$_POST可变NO键接收表和最新MYSQL

<?php 

include "conecta.php"; 
include "verifica.php"; 

\\THIS PART WORKS, GETS IF THE CHECKBOX IS CHECKED AND RECORD IT ON DB 

if(isset($_POST['user'])) { 
    foreach ($_POST['user'] as $key => $read){ 
     $read =(@$_POST['user']=='0')? $_POST['user']:'1'; 
     echo $read; 
     $sql = "UPDATE categorias SET mostrar='$read' WHERE ordem='$key'"; 
     $res = mysql_query($sql) or die ("Erro ao excluir") . mysql.error(); 
    } 
} 

\\ON THIS PART OF THE CODE THAT I CANT GET THE VARIABLE TO GET THE 
\\VALUE FROM CHEBOXES THAT ARE UNCHECKED RECORDED TO DATABASE 

if (!isset($_POST['user'])) { 
    foreach ($_POST['user'] as $chave => $leia) { 
     $leia =(@$_POST['user']=='1')? $_POST['user']:'0'; 
     echo $leia; 
     $sql = "UPDATE categorias SET mostrar='$leia' WHERE ordem='$chave'"; 
     $res = mysql_query($sql) or die ("Erro ao excluir") . mysql.error(); 
    } 
} 

?>

的代码。如果它被选中，则该键将被设置并且该值将是该复选框的值。

假设 “用户[]” 的作品名称，喜欢的东西：

<input type="checkbox" name="user[]" value="aa" /> 
<input type="checkbox" name="user[]" value="bb" checked="checked" /> 
<input type="checkbox" name="user[]" value="cc" checked="checked" /> 
<input type="checkbox" name="user[]" value="dd" /> 
<input type="checkbox" name="user[]" value="ee" checked="checked" />

你会期望$_POST是：

array(
    "user" => array(
     "1" => "bb" 
     "2" => "cc" 
     "4" => "ee" 
    ) 
);
