====== System variables ======

===== index.php?id=0,0,0,0,0,0 =====

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

<file>
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
</file>
Provided at: /include/inc_front/content.func.inc.php

<code php>$aktion = array(0,0,0,0,1,0);</code>
<code php>
$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($aktion[5]) : 0;                //  free use
</code>
Request using **$GLOBALS['aktion']**

\\

==== Examples: ====
**
The category ID:** 
<code php>echo 'Cat-ID: '.$GLOBALS['aktion']['0'];</code>

\\
**The article ID** //(Output only in article detail view)//:
<code php>echo 'Article-ID: '.$GLOBALS['aktion']['1'];</code>
\\
When we are in category view? [1=Yes|0=No] \\
<code php>echo 'CatShow: '.$GLOBALS['aktion']['3'];</code>
\\
When we are in article detail view? [1=Yes|0=No]: \\
<code php>echo 'Detail: '.$GLOBALS['aktion']['4'];</code>
\\
**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)// \\
<code>
    [0] => 7   // category-ID
    [1] => 26  // article-ID
    [2] => 0
    [3] => 1   // category view
    [4] => 1   // article detail view
    [5] => 0
</code>
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)// \\
<code>
    [0] => 2   // category-ID
    [1] => 0
    [2] => 0
    [3] => 1   // category view
    [4] => 0
    [5] => 0
</code>
As a link: ''%%index.php?id=2,0,0,1,0,0%%''


  * In article detail view e.g. (article ID=6):<code>
    [0] => 2   // category-ID
    [1] => 6   // article-ID
    [2] => 0
    [3] => 0
    [4] => 1   // article detail view   
    [5] => 0
</code>As a link: ''%%index.php?id=2,6,0,0,1,0%%''

===== Var Dump =====
Be shure you have set in conf.inc.php<code php>$phpwcms['allow_cntPHP_rt'] = 1; //allow PHP replacement tags and includes in content parts</code>

<code php>
<!-- Var Dump =================== //-->
[PHP] 

echo '<pre>LEVEL ID</pre>';
dumpVar($GLOBALS['LEVEL_ID']);
echo '<pre>LEVEL KEY</pre>';
dumpVar($GLOBALS['LEVEL_KEY']);
echo '<pre>LEVEL STRUCT</pre>';
dumpVar($GLOBALS['LEVEL_STRUCT']);

echo '====================== <br /> ';

dumpVar($GLOBALS['content']["articles"]); // article-structure
dumpVar($GLOBALS['content']["struct"]);   // category-structure

// article list mode: if more then one article available and in site structure -> category -> top article count: > 1
dumpVar($GLOBALS['content']["list_mode"]);   // (true|false)   

// top article count for article list mode in site structure -> category -> top article count: 
dumpVar($GLOBALS['content']['struct'][$content['cat_id']]['acat_topcount']; // (count) 

// Article title of the current article (detail mode)
dumpVar($GLOBALS['content']['article_title']);

// Article subtitle of the current article (detail mode)
dumpVar($GLOBALS['content']['articles'][$GLOBALS['content']['article_id']]['article_subtitle']);

===== Read keyword from article =====



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:

<code php>
$keywords_array = convertStringToArray($GLOBALS['content']['all_keywords']);
</code>

\\



**E.g.:** //Forum [[http://forum.phpwcms.org/viewtopic.php?p=120863#p120863|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."//



{{:deutsch:technik:article_keyword_de.gif|}}

**frontend_init**
<code php>
if(strpos($content['all_keywords'], '*CSS-dark*') !== false) {
   $template_default['body']['class'] = 'dark level-';
   $content['all_keywords'] = str_replace('*CSS-dark*', '', $content['all_keywords']);
}
?>
</code>
**
CSS:**
<code php>
body.dark {
  background-color: #666666;
}
</code>

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

===== GET variable set and read =====

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

=== Preparing the address: ===

<code php>
	$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=';
</code>
\\

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

<code php>
$my_number = 34;

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

=== Read variable: ===

<code php>
// 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
</code>

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

\\

=== Use as tag: ===
 
<code PHP>
    {PHPVAR:$GLOBALS['_getVar']['cpimage']}
</code>
