在PHP + AJAX中插入多个复选框的值

Question

我试图插入多个复选框值到数据库使用Ajax，但我不知道我能为这种方法做什么。我用这些代码试了一下。

 <h3 class="page-header">International Language</h3> 
         <div class="form-group"> 
         <label class="col-md-3 control-label" for="">Chinese</label>

您正在使用非常漫长而麻烦的方式来获取值。使用复选框时，请尝试以下方法来获取值。

var selected = new Array(); 
$('#checkboxes input:checked').each(function() { 
    selected.push($(this).attr('name')); 
}); 

而使用可以使用这个数组来发送值。

但是，当我看到您的HTML时，您根本不需要获取单个变量，因为所有复选框的名称均为“chk []”，将数据作为数组发布。您可以直接提交表单，为所有选中的阵列将可作为：

$values = $_GET['chk']; 
echo '<pre>';print_r($values);echo '</pre>'; 

它应该给类型（注意只选中的复选框值将作为可用）的结果。

array(1=>'greek',2=>'french') etc. 

然后，您可以使用foreach循环来管理这些值。
