使用PHP PDO不更新所有复选框更新复选框的数据库值 [英] Update database values for checkboxes using PHP PDO not updating all checkboxes

问题描述

我有3行，每行有一个复选框，当我取消选中所有框，然后单击保存我收到错误在我的else语句。如果我一次取消选中框并点击保存，当我到达最后一个复选框，然后点击保存我也收到错误的else语句。

I have 3 rows and each row has a checkbox, when I uncheck all boxes and click save I receive the error in my else statement. If I uncheck on box at a time and click save, when I get to the last checkbox and click save I also receive the error in the else statement.

这里是我的

这是我的PHP代码：

//Update Social Preferences with new value for display on homepage
$settingsArray = array('myfacebook', 'mytwitter', 'mygoogle');
if(isset($_POST['btn-save']))
{          
      if(isset( $_POST['mysocial']))
      {
          $values = array();
      foreach($_POST['mysocial'] as $selection )
      {  if(in_array($selection, $settingsArray))
         {  $values[ $selection ] = 1; }
         else
         {  $values[ $selection ] = 0; }
      } // end of foreach.

      $user_id = $_SESSION['user']['id'];

      try // save user selection to the database
      {

        $stmt = $db->prepare("UPDATE social_preferences SET my_facebook = :myfacebook, my_twitter = :mytwitter, my_google = :mygoogle WHERE user_id = :userID");
        $stmt->bindParam(":userID", $userid, PDO::PARAM_INT);
        $stmt->bindParam(':myfacebook', $values['myfacebook']);
        $stmt->bindParam(':mytwitter', $values['mytwitter']);
        $stmt->bindParam(':mygoogle', $values['mygoogle']);
        $stmt->execute();

        header("Location: admin-social-test.php"); 
        die("Redirecting to admin-social-test.php"); 
       }  catch(PDOException $e) { echo 'Connection failed: ' . $e->getMessage(); }
  }
  else
  {  $noCheckbox = 'No checkbox selection made...'; }     
} // End of, if statement from the button check 

这是我的HTML代码：

Here is my HTML Code:

<input type="checkbox" name="mysocial[]" value="myfacebook" <?php echo ($result['my_facebook']==1 ? 'checked' : '');?> />
<input type="checkbox" name="mysocial[]" value="mytwitter" <?php echo ($result['my_twitter']==1 ? 'checked' : '');?> />
<input type="checkbox" name="mysocial[]" value="mygoogle" <?php echo ($result['my_google']==1 ? 'checked' : '');?> />

推荐答案

所以我改变了这一点：

<input type="checkbox" name="mysocial[]" value="myfacebook" <?php echo ($result['my_facebook']==1 ? 'checked' : '');?> />
<input type="checkbox" name="mysocial[]" value="mytwitter" <?php echo ($result['my_twitter']==1 ? 'checked' : '');?> />
<input type="checkbox" name="mysocial[]" value="mygoogle" <?php echo ($result['my_google']==1 ? 'checked' : '');?> />

到此：

<input type="hidden" name="mysocial[]" value="myfacebook1" <?php echo ($result['my_facebook']==1 ? 'checked' : '');?> />
<input type="checkbox" name="mysocial[]" value="myfacebook" <?php echo ($result['my_facebook']==1 ? 'checked' : '');?> />
<input type="hidden" name="mysocial[]" value="mytwitter1" <?php echo ($result['my_twitter']==1 ? 'checked' : '');?> />
<input type="checkbox" name="mysocial[]" value="mytwitter" <?php echo ($result['my_twitter']==1 ? 'checked' : '');?> />
<input type="hidden" name="mysocial[]" value="mygoogle1" <?php echo ($result['my_google']==1 ? 'checked' : '');?> />
<input type="checkbox" name="mysocial[]" value="mygoogle" <?php echo ($result['my_google']==1 ? 'checked' : '');?> />

这似乎已经奏效了。
