HTML表格中的`iframe`

Question

I am displaying some data from a database into my cms, using tables (tr, td).

   <tr align="center">
        <td><?php echo $i++; ?></td>
        <td><?php echo $post_image; ?></td>
        <td><?php echo $post_title; ?></td>
        <td>
            <iframe width="100px" frameborder="0" id='inneriframe' scrolling=yes >
                <?php echo $post_description; ?>
            </iframe>
        </td>
        <td><a href="index.php?edit_football_news=<?php echo $post_id; ?>">Edit</a></td>
        <td><a href="includes/delete_football_news.php?delete_football_news=<?php echo $post_id; ?>">Delete</a></td>
    </tr>

Unfortunately the description php variable is not displayed at all inside my iframe. However, if I take out the iframe tag, everything works fine, and I can see all the stored values from the database.

<tr align="center">
        <td><?php echo $i++; ?></td>
        <td><?php echo $post_image; ?></td>
        <td><?php echo $post_title; ?></td>
        <td><?php echo $post_description; ?></td>

        <td><a href="index.php?edit_football_news=<?php echo $post_id; ?>">Edit</a></td>
        <td><a href="includes/delete_football_news.php?delete_football_news=<?php echo $post_id; ?>">Delete</a></td>
    </tr>

So my main question is how to use iframes inside tds?

Answer 1

iframe elements load external documents; the HTML that goes between their start and end tags is alternative content for browsers which do not support iframes.

If you want a scrolling area on a page, apply the CSS overflow property to an appropriate element (probably a div in this case).
