From my personal website

In my personal web-site I use several customized markups, templates, etc. While many of those may not be even relevant to other people, you may find a few concepts useful for your site. So in this section I will share with you the customizations I use in my site.

[NOTE: Some of the contents below are adopted from or inspired by ideas discussed by other users in PmWiki. They deserve the full credit for the ideas. No violation of intellectual property rights intended. The sole purpose of the discussions below is to help other users of PmWiki.]

Custom Markups: cookbook/mymarkup.php

In config.php: include_once('cookbook/mymarkup.php');

<?php if (!defined('PmWiki')) exit ();

// Constants

// HTML markups - by Hagan Fox
Markup(
  'html',
  'fulltext',
  '/\\(:html:\\)(.*?)\\(:htmlend:\\)/esi',
  "'<:block>'.Keep(str_replace(array('&gt;', '&lt;', '&amp;'),
  array('>', '<', '&'), PSS('$1')))");

// [[*PathToFile]] - to create links to files on file server http://www.subhrajit.net/
Markup('ExtLinks', 'fulltext', "/\\[\\[\\*\\s*(.*?)\\s*\\]\\]/esi", "Keep('<a href=\"http://www.subhrajit.net/files/'.PSS('$1').'\">'.basename(PSS('$1')).'</a>')");

// [% ... %] comment
Markup('blockcomment','_begin','/\\[%(.*?)%\\]/esi',"Keep('')");

// (:preg_include [include_options] regex=/.../ies delimiter=... [pindex=0]:)
Markup('preginclude', '>include',
  '/\\(:preg_include\\s+(\\S.*?)\\s+regex\\s*=\\s*(.*?)\\s+delimiter\\s*=\\s*"(.*?)"\\s*:\\)/ei',

  				array("\\n", "\\r", "\\t"),
  				array("\n",  "\r",  "\\t"),
  				$delimiter );
  return(implode($delimiter, $theMatches[$pindex]));
}

Custom Page variables: cookbook/mypagevariables.php

In config.php: include_once('cookbook/mypagevariables.php');

<?php

$FmtPV['$MaxUploadSize'] = 'min(intval(ini_get("upload_max_filesize")), intval('.$UploadMaxSize/(1024*1024).')) . " M"';
$FmtPV['$PageCreationDate'] = 'strftime("%b %d, %Y", $page["ctime"])';

$thispagename = @$_REQUEST['n'];
$thispage = ReadPage($thispagename);
$FmtPV['$RawTitle'] =  '"'.$thispage['title'].'"';


?>

Custom Markup Expressions: cookbook/mymarkupexpressions.php

In config.php: include_once('cookbook/mymarkupexpressions.php');

<?php

$MarkupExpr['md5'] = 'md5($args[0])';
$MarkupExpr['_GET'] = '$_GET["$args[0]"]';

// {(GETrequest "http://www.theurl.com/index.php" "arg1=value1" "arg2=value2" ... )}
$MarkupExpr['GETrequest'] = 'GETrequest($args)';
function GETrequest($theArgs) {
    $theURL = $theArgs[0].'?';
    for ($a=1; $a<sizeof($theArgs); $a++) {
        $argParts = explode('=', $theArgs[$a], 2);
        $theURL = $theURL.$argParts[0].'='.urlencode($argParts[1]).'&';
    }
    return file_get_contents($theURL);
}

?>

Custom Conditions: cookbook/myconditions.php

In config.php: include_once('cookbook/myconditions.php');

<?php

$Conditions['doesPagenameContainDash'] = "preg_match('/-/',FmtPageName('\$Name',\$pagename))";
$Conditions['action'] = '\$GLOBALS["action"]==\$condparm';

$Conditions['StringEquals'] = 'parseStringEqual($condparm)';
function parseStringEqual($condstatement) {
	$strParts = explode('==', $condstatement);
	return (trim($strParts[0])==trim($strParts[1]));
}

?>
