Hi :-)

in file cat_modify.php line 406

$template->assign_var_from_handle('ADMIN_CONTENT', 'album_properties');

--------------

in your code
$template->set_prefilter('cat_modify', 'PMV_cat_modify');

can you test

$template->set_prefilter('album_properties', 'PMV_cat_modify');

Hi again!

As I almost thought the next step to my successful plugin is not working :-( .

I guess it's because I'd like to add information to the index.tpl. My naive thoughts were to create a file like the image.php from the copyrights plugin and modify it.

But this code seems to be wrong because nothing appears on the category page by adding information before {if !empty($CONTENT)}{$CONTENT}{/if} in the index.tpl.

add_event_handler('loc_begin_index', 'pmv_set_prefilter_add_infos_to_index', 50 );
add_event_handler('loc_begin_index', 'pmv_add_index_vars_to_template');

function pmv_set_prefilter_add_infos_to_index()
{
  global $template;
  $template->set_prefilter('index', 'pmv_add_infos_to_index');
}

Maybe someone could give me a hint.

Thanks
Harry

I checked out that the category view is created by piwigo/themes/default/templateplate/index.tpl (I simply added a few characters manually and they were shown in my front end).

I want to add some information after the content description and before the content itself. That means line 165 in the mentioned index.tpl.

I only wrote a few lines for testing yet. Maybe the variable for the category id is wrong again but this is not the problem. When I just try to assign simple text without any data from the database nothing is shown on the front end.

function pm_add_infos_to_index($content, &$smarty)
{
  // Add the information before the content
  $search = '#{if !empty($CONTENT)}{$CONTENT}{/if}#';
  
  $replacement = '
  <p>
        {$PMV_MANUFACTURER}<br>
  {$PMV_NAME}<br>
        {$PMV_YEAR}<br>
  </p>
  
  {if !empty($CONTENT)}{$CONTENT}{/if}
  ';

  return preg_replace($search, $replacement, $content, 1);
}

// Assign values to the variables in the template
function pm_add_index_vars_to_template()
{
  global $page, $template, $prefixeTable;

  // Show block only on the category page
  if ( isset($_GET['cat_id']) )
  {
    // Get the information that belongs to the current category
    $query = sprintf('
      select *
      FROM %s
      WHERE cat_id = %d
    ;',
    PMINFO_DATA, $_GET['cat_id']);
    $result = pwg_query($query);
    $row = pwg_db_fetch_assoc($result);
    
    // Get the data from the chosen row
    $manufacturer = $row['manufacturer'];
    $name = $row['name'];
    $year = $row['year'];
      
    // Sending data to the template
    $template->assign('PMV_MANUFACTURER', $manufacturer);
    $template->assign('PMV_NAME', $name);
    $template->assign('PMV_YEAR', $year);
  }
}

Thanks for the hint. Unfortunately it doesn't work.

As I realized that it may be difficult to use template variables within the replacement search I tried another place in the template and simply assigned a text with

function pmv_add_index_vars_to_template()

$name = "This is a test";
$template->assign('PMV_NAME', $name);

and the replacement was this

  $search = '#FILE_CHRONOLOGY_VIEW}
{/if}#';
  
  $replacement = '
FILE_CHRONOLOGY_VIEW}
{/if}

  <p>
  {$PMV_NAME}<br>
  </p>
  
  ';

...without success.

Hello!

I did it and it worked. I replaced the title </h2> of the index.tpl with my simple text function and it was shown on the category page front end. I also found out that the category is stored in $page['category']['id'].

Now I only need to know how to put my text at the place I want it to. I guess the problem are the smarty functons inside the template which can't be simply replaced by preg_replace.

On the other hand: Maybe I rebuilt the page a little bit by putting my additional information directly under the page title as I did it for testing. I guess that would be the easiest way to do.

However, then it still would be interesting for later use how to replace smarty functions inside the template.
