Question

当我为messages对象返回数据行时，此代码有效，但是如果没有，则返回NULL，在这种情况下，我很难让此代码仍然正确显示，以便它可以与标签插件我起来了。我正在为我的桌子使用数据表。

有人有什么想法吗？

Answer 1

echo '<tr>';
echo 'No records';
echo '</tr>';

需要td

echo '<tr><td colspan="5">';
echo 'No records';
echo '</td></tr>';

javascript和tabs插件的实例化似乎存在问题。我没有在任何地方看到标签的js。但我确实看到选择中页面上存在CI错误：

<select name="to" class="required">
                                        <option></option>

                                        <div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">

<h4>A PHP Error was encountered</h4>

<p>Severity: Warning</p>
<p>Message:  Invalid argument supplied for foreach()</p>
<p>Filename: views/pmsystem.php</p>
<p>Line Number: 121</p>

</div>                                    </select>

有时会搞乱javascript的东西。

你在错误控制台中得到了什么吗？

我们可以看到js吗？

返回NULL不能使用制表符插件
