在使用ajax实时搜索实现PHP和MySQL的最后阶段，我需要一些建议。
我让实时搜索工作得很完美，它会按照我想要的方式显示结果。我甚至通过URL传递搜索值并在页面加载时搜索来实现它。
我遇到的问题是，当它打印结果时，它不打印列的名称，只显示例如值：
<table data-role="table" id="customer" data-mode="reflow" class="border_radius">
<thead>
<tr class="">
<td>ID</td>
<td>Name</td>
<td>Address</td>
<td>Post Code</td>
<td></td>
</tr>
</thead>
<tbody>
<td id="" class="151">151</td>
<td id="" class="Brain">Brain</td>
<td id="" class="Apartado 81">Apartado 81</td>
<td id="" class="2584">2584</td>
<td>
<a href="cart/?tele=" class="btn btn-success btn-lg text-center" id="order_link" '="">Order</a></td></tbody>
</table>
这个问题是我想将值发布到下一页的网址，但不知道如何实现这一点。我试图发布列名，但它会为每个id发布所有列名，如下所示：
<table data-role="table" id="customer" data-mode="reflow" class="border_radius">
<thead>
<tr class="">
<td>ID</td>
<td>Name</td>
<td>Address</td>
<td>Post Code</td>
<td></td>
</tr>
</thead>
<tbody>
<td id="AUTO_ID, NAME, ADDRESS, ZIP_CODE" class="151">151</td>
<td id="AUTO_ID, NAME, ADDRESS, ZIP_CODE" class="Brain">Brain</td>
<td id="AUTO_ID, NAME, ADDRESS, ZIP_CODE" class="Apartado 81">Apartado 81</td>
<td id="AUTO_ID, NAME, ADDRESS, ZIP_CODE" class="2584">2584</td>
<td>
<a href="cart/?tele=" class="btn btn-success btn-lg text-center" id="download_link" '="">Order</a></td></tbody>
</table>
