php - 在特定条件后如何显示表格？

Question

我是这样编码的，上传Excel文件时，Excel中的数据列表将显示在表格中。

现在的问题是删除数据，下面的特定行单独显示。

<tr>
    <th>Title</th>
    <th>First Name</th>
    <th>Last Name</th>
    <th>Email</th>
    <th>Phone</th>
    <th>Options</th>
    <th><input type="checkbox"  name="delete_all" class="" value='' onClick="deleteAll()"  /></th>
</tr>  

我希望仅当超过一行时才显示整个表格。请帮我解决这个问题。

<form name="del_functionality" method="post" action="<?php echo $_SERVER['PHP_SELF'];     ?>">
    <div class="control-group">
        <div class="controls" align="right">        
            <button type="submit" id="deletes" name="delete" value="delete"  data-loading-text="Loading..." onClick="return deleteSelected()">Delete </button>
        </div>
    </div>

    <table class="table">
        <tr>
            <th>Title</th>
            <th>First Name</th>
            <th>Last Name</th>
            <th>Email</th>
            <th>Phone</th>
            <th>Options</th>
            <th><input type="checkbox"  name="delete_all" class="" value='' onClick="deleteAll()"  /></th>
        </tr>
    <?php
        $res=mysql_query("SELECT * FROM dealer_tbl");
        while($dealer_row=mysql_fetch_array($res))
        {
        ?>
            <tr>

                <td><?php echo $dealer_row['title']; ?></td>
                <td><?php echo $dealer_row['firstname']; ?></td>
                <td><?php echo $dealer_row['lastname']; ?></td>
                <td><?php echo $dealer_row['email']; ?></td>
                <td><?php echo $dealer_row['phone']; ?></td>
                <td align="center"><a href='dealer_edit.php?did=<?=$dealer_row['uid']?>'>Edit</a> </td>
                <td>
                    <input type="checkbox"  name="checkbox_del[]" class="deleteCheckbox" value="<?php echo $dealer_row['uid']; ?>"  />
                    <input type='hidden' name='deleteConfirm' value='0' />
                </td> 
            </tr>
        <?php
        }
    ?>
    </table>
</form> 

Answer 1

更改查询位置，如下所示:

<?php 
      $res=mysql_query("SELECT * FROM dealer_tbl");
      $count =mysql_num_rows($res);
 ?>
 <table class="table" <?php if($count == 0) { ?> style="display:none;" <?php }?>>
 ...
 </table>
