Title: Question about language of template. {if...} ... {endif...} form
Post by: taru on October 21, 2009, 09:17:13 PM

In my gallery every detail viewed picture at the same time is a link to the next image in the folder.
So it so easy to view all pictures to the end of the folder simply by clicking to the image.

I have change my details.html:

Code: [Select]

<div align="center">
   {image}
       {if admin_links}<br />
           {admin_links}<br />
       {endif admin_links}<br />
   {lightbox_button}&nbsp;&nbsp;{postcard_button}&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{download_button}&nbsp;&nbsp;{download_zip_button}
</div>

to this:

Code: [Select]

<div align="center">

          {if next_image_name}
          <a href="{next_image_url}" alt="{image_name}" title="{image_name}">
          {endif next_image_name}

   {image}
       {if admin_links}<br />
           {admin_links}<br />
       {endif admin_links}<br />
   {lightbox_button}&nbsp;&nbsp;{postcard_button}&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{download_button}&nbsp;&nbsp;{download_zip_button}
</div>

When last image in folder is reached - nothing is happen because next_image_name is false. But I want in this case change href to {cat_url}.
How can I use if...else...endif structure here?
Or how can I use logical negation?  Something like this...  {if !next_image_name}  ?
Could someone help me?

you can use {ifno tag}:

Code: (HTML template) [Select]

<div align="center">

  {if next_image_name}
  <a href="{next_image_url}" alt="{image_name}" title="{image_name}">
  {endif next_image_name}

  {ifno next_image_name}
  <a href="{cat_url}" alt="{image_name}" title="{image_name}">
  {endifno next_image_name}

    {image}

   </a>

  {if admin_links}<br />
    {admin_links}<br />
  {endif admin_links}<br />

  {lightbox_button}&nbsp;&nbsp;{postcard_button}&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{download_button}&nbsp;&nbsp;{download_zip_button}

</div>

Thanks V@no!

Works fine in 1.7.7!
And one more question. Is there any way to link to the first image in the folder? I think may be better when last image in folder is reached then link to the first image...

I have another site with old version 1.7.1. There don't working {ifno tag}  :(

that would require little .php modification. You can leave template as it is now and in details.php find:
$next_image_id = (isset($image_id_cache[$act_key + 1])) ? $image_id_cache[$act_key + 1] : 0;

Replace it with:
$next_image_id = (isset($image_id_cache[$act_key + 1])) ? $image_id_cache[$act_key + 1] : $image_id_cache[0];

[1.7.1] Conditional tags inside other conditional tags + {ifno ...}{endifno ...} (http://www.4homepages.de/forum/index.php?topic=7493.0)
