Expression Engine - Help with static code inside e

问题:

I've managed to sort the last li issue, but can't seem to now link my last list item back to the latest entry in the specific category. Any ideas?

{exp:channel:entries channel="project" limit="6" category_group="1" stop_before="{embed:stop_before}" related_categories_mode="yes" custom_fields="yes"}
{if count == "1"}<ul id="filmStrip">{/if}
<li>
{exp:imgsizer:size src="{project_image}" height="68px" width="137px"}
<a href="{title_permalink='projects-test/view'}"><img src="{sized}" height="{height}" width="{width}" alt=""/></a>
{/exp:imgsizer:size}
<a href="{title_permalink='projects-test/view'}"><p class="thumbTitle">{title}</p></a>
</li>
{if total_results <= '5' AND total_results == count}
    <li>
        <a href="{path='projects-test/view'}/{first_entry_id}"><img src="../../../images/backtostart.jpg" height="68px" width="137px" alt=""/></a>
        <a href="{path='projects-test/view'}/{first_entry_id}"><p class="thumbTitle">Back to start</p></a>
    </li>
{/if}
{if count == total_results}</ul>{/if}
{/exp:channel:entries}

回答1:

One issue is that you're using the {count} and {total_results} variables outside of the channel:entries loop, which won't work.

Here's how you can limit the display of the "back" link in this manner, and also link to the first entry in that category (by "first" I assume you mean "newest"):

{exp:channel:entries channel="project" limit="6" category_group="1" stop_before="{embed:stop_before}" related_categories_mode="yes" custom_fields="yes"}
{if count == "1"}<ul id="filmStrip">{/if}
<li>
    {exp:imgsizer:size src="{project_image}" height="68px" width="137px"}
    <a href="{title_permalink='projects-test/view'}"><img src="{sized}" height="{height}"   width="{width}" alt=""/></a>
    {/exp:imgsizer:size}
    <a href="{title_permalink='projects-test/view'}"><p class="thumbTitle">{title}</p></a>
</li>
{if count == total_results}
    {if count == "5"}
    {categories show_group="1" limit="1"}
    {exp:query sql="SELECT t.entry_id as first_entry_id FROM exp_channel_titles t LEFT JOIN exp_category_posts c ON t.entry_id = c.entry_id WHERE c.cat_id = {category_id} AND t.status = 'open' ORDER BY t.entry_date DESC LIMIT 1"}
    <li>
        <a href="{path='projects-test/view'}/{first_entry_id}"><img src="../../../images/backtostart.jpg" height="68px" width="137px" alt=""/></a>
        <a href="{path='projects-test/view'}/{first_entry_id}"><p class="thumbTitle">Back to start</p></a>
    </li>
    {/exp:query}
    {/categories}
    {/if}
</ul>{/if}
{/exp:channel:entries}

I haven't tested this, so let me know if it throws a fit.

UPDATE: Things to try to get the "first entry" query to work:

• Add parse="inward" to the exp:query tag.
• Try running the SQL query directly via the SQL Manager within the EE control panel (substituting a category_id for the {category_id} variable), and see if that returns the correct entry_id.
• Remember that this code assumes that each project will only have one category assigned to it in that category group.

The nested {if} statement I used above should work - and it's better to use that than the advanced one you updated your original post with, as it will cause the query statement to run every time.
