Question

我有网站，用户可以选择喜欢的网站，访问网站的日期，评论当天他们访问的网站是否满意。最初有四行是硬编码的并插入到mysql数据库中。然后有一个添加按钮，使用户可以选择更多网站添加到现有网站，以及相关的访问和评论日期。问题是如何将其他选定的fav网站插入数据库。

这是我的代码jsfiddle.net/j8odptds/

         var cloneIndex = $('#websites').length+4;  
         $('#add').on('click', function() {
          var newElem = $('#websites').clone().appendTo('#addMoreWebsite').attr('id','website' + cloneIndex);
          $(newElem).find('[id=website4]').attr('name','website' + (cloneIndex));
          $(newElem).find('[id=website4]').attr('id','website' + (cloneIndex));

          $(newElem).find('[id=Date4]').attr('name','Date' + (cloneIndex));
          $(newElem).find('[id=Date4]').attr('id','Date' + (cloneIndex));

          $(newElem).find('[id=Comments4]').attr('name','Comments' + (cloneIndex));
          $(newElem).find('[id=Comments4]').attr('id','Comments' + (cloneIndex));

            cloneIndex++; 
        });

Answer 1

您必须将所有值作为数组传递给PHP。因此，您的所有输入都必须为name="namespace[rowId]name"。在PHP中，您只需循环该数组并将所有值插入数据库。

<div class="wrapper">
    <input type="text" name="Website[0]name"/>
    <select name="Website[0]rating"><option></option></select>
</div>

<button type="button" onClick="addRow()">Add row</button>

var lastRow = 0;
function addRow() {
    lastRow++;
    $('.wrappper').append(
        '<input type="text" name="Website[' + lastRow + ']name"/>'
        + '<select name="Website[' + lastRow + ']rating"><option></option></select>'
    );
}

[php]
foreach ($_POST['Website'] as $website) {
    $this->db->insert(array(
        'name' => $website['name'],
        'rating' => $website['rating'],
    ));
}
