System variables

System-oriented link representation of category, article, print.
This representation can be used actively to operate as a link or query the existing status.

0 = structure ID
1 = article ID
2 = e.g. if 1 then print
3 = if 1 then show category
4 = if a link to an article then show (1)
5 = free use

Provided at: /include/inc_front/content.func.inc.php

$aktion = array(0,0,0,0,1,0);

$aktion = explode(',', $_GET["id"], 6);
$aktion[0] = intval($aktion[0]); //$aktion[0] will be always available  //  structure ID
$aktion[1] = isset($aktion[1]) ? intval($aktion[1]) : 0;                //  article ID
$aktion[2] = isset($aktion[2]) ? intval($aktion[2]) : 0;                //  e.g. if 1 then print
$aktion[3] = isset($aktion[3]) ? intval($aktion[3]) : 1;                //  if 1 then show cat
$aktion[4] = isset($aktion[4]) ? intval($aktion[4]) : 0;                //  if a link to an article then show (1)
$aktion[5] = isset($aktion[5]) ? intval($aktion[5]) : 0;                //  free use

Request using $GLOBALS['aktion']

The category ID:

echo 'Cat-ID: '.$GLOBALS['aktion']['0'];

The article ID (Output only in article detail view):

echo 'Article-ID: '.$GLOBALS['aktion']['1'];

When we are in category view? [1=Yes|0=No]

echo 'CatShow: '.$GLOBALS['aktion']['3'];

When we are in article detail view? [1=Yes|0=No]:

echo 'Detail: '.$GLOBALS['aktion']['4'];

Assumption: A category (ID=7) operating in simple article mode (ID=26) (Top article count: -1, or if the number of top articles: > 1 and article count = 1)

    [0] => 7   // category-ID
    [1] => 26  // article-ID
    [2] => 0
    [3] => 1   // category view
    [4] => 1   // article detail view
    [5] => 0

As a link: index.php?id=7,26,0,1,1,0

Assumption: A category (ID=2) operating in article list mode (ID=26,6,5,3) (Top article count: > 1, article count > 1)

    [0] => 2   // category-ID
    [1] => 0
    [2] => 0
    [3] => 1   // category view
    [4] => 0
    [5] => 0

As a link: index.php?id=2,0,0,1,0,0

• In article detail view e.g. (article ID=6):

      [0] => 2   // category-ID
      [1] => 6   // article-ID
      [2] => 0
      [3] => 0
      [4] => 1   // article detail view
      [5] => 0

  As a link: index.php?id=2,6,0,0,1,0

Be shure you have set in conf.inc.php

$phpwcms['allow_cntPHP_rt'] = 1; //allow PHP replacement tags and includes in content parts

<!-- ====================== //-->

The variable $content['all_keywords'] (or $GLOBALS['content']['all_keywords'] if used in functions ) supplies the Keywords of the current article.

E.g.: Write the keywords into an array:

$keywords_array = convertStringToArray($GLOBALS['content']['all_keywords']);

E.g.: Forum Css eines Artikels ändern [DE]

A special CSS formatting for an article:

Question:

“If I liked to indicate a special css for only one article , where will I do that? > > For explanation, I would like to have individual articles with a dark instead of a bright page background.”

Answer:

“I would work with a special keyword by using a frontend_render script to trigger it accordingly. Set the keyword “*CSS-dark*” into the appropriate fiel dof the article. When rendering is checked out the <body> tag is enhanced by the corresponding class. This normally can be defined via CSS.”

frontend_init

if(strpos($content['all_keywords'], '*CSS-dark*') !== false) {
   $template_default['body']['class'] = 'dark level-';
   $content['all_keywords'] = str_replace('*CSS-dark*', '', $content['all_keywords']);
}
?>

CSS:

body.dark {
  background-color: #666666;
}

Attention - the class(es) “dark level-” were selected intentionally in such a way, since still additionally the level ID is given.

Update 25.06.2009: Revision: r317

Now it is possible to select the current category ID related to the level.

Have a look: Standard tags assembled

Example: The variable is called “cpimage” and is containing an integer value.

    $site         = $GLOBALS['phpwcms']['site'].$GLOBALS['phpwcms']['root'];
    $cat_alias    = $GLOBALS['content']["struct"][$GLOBALS['content']["cat_id"]]["acat_alias"];
    $href_str    = $site.'index.php?'.$cat_alias;
    $get_str    = 'cpimage=';

z.B. http://my_site.tld/index.php?active_category&cpimage=34

$my_number = 34;
 
$my_complete_link = $href_str.'&'.$get_str.$my_number; // http://my_site.tld/index.php?active_category&cpimage=34

// Is there a GET var?
if (isset($GLOBALS['_getVar']['cpimage'])) {
 
    $GLOBALS['_getVar']['cpimage'] = intval($GLOBALS['_getVar']['cpimage']);  // Convert to integer
    $cpImgNr = $GLOBALS['_getVar']['cpimage'];
}
else    $cpImgNr = false;  // if there is no GET var set it to false

The integer value in $cpImgNr can be processed now, but should be checked prior to “false”.

    {PHPVAR:$GLOBALS['_getVar']['cpimage']}

Check if a news CP is in the detail view:

    if(isset($_getVar['newsdetail'])) { .....
