[TYPO3-templavoila] FCE File-Download

[Bart Veldhuizen [V-INT]]

Hi Jens,

I've done the same thing a few weeks ago:

http://www.zonmw.nl/nl/programma-s/alle-programma-s/diabetes- 
ketenzorg/actueel/

I created an FCE that contains a section with download link  
containers. Next, I'm using a userFunc to determine both the file's  
class (for displaying the right icon) and its filesize in KB or MB  
for each file in the section. The TV XML contains the following TS  
code; it passes the file information to a custom PHP script:

<TypoScript><![CDATA[
	10 = COA
	10 {

		10 = TEXT
		10 {
			field = field_download_file
			postUserFunc = user_get_fileclass
			wrap = <li class="|">
		}

		20 = TEXT
		20 {
			field  = field_download_title
			typolink.parameter.field = field_download_file
		}

		30 = TEXT
		30 {
			field = field_download_file
			postUserFunc = user_get_filedesc
		}	
		
		40 = TEXT
		40.value = </li>

	}
	
]]></TypoScript>



Here's the user functions file in case you're interested:



<?
	/***
	 *
	 */
	function user_get_fileclass($strUrl, $arrOpt)
	{
		// bepaal extensie
		$strExt = strrchr( $strUrl, '.' );
		$strExt = strtolower( $strExt );
		$strExt = substr( $strExt, 1 );
		
		return( $strExt );
	}
	

	function user_get_filedesc($strUrl)
	{
		// bepaal filesize
		$strDocRoot = '<ENTER YOUR DOCROOT HERE>';

		$strFile = $strDocRoot . $strUrl;
		$strFile = urldecode( $strFile );
				
		$intFileSize = filesize( $strFile );
		
		if( $intFileSize < 1024*1024 ) {
			$intFileSize = (int)$intFileSize / 1024;
			$strFileSizeIndicator = 'KB';
		} else {
			$intFileSize = (int)$intFileSize / (1024*1024);
			$strFileSizeIndicator = 'MB';
		}
		
		// tot 1 cijfer achter de comma
		$intFileSize = round( $intFileSize, 1 );
		
		// bepaal extensie
		$strExt = strrchr( $strUrl, '.' );
		$strExt = strtoupper( $strExt );
		$strExt = substr( $strExt, 1 );
		
		$strResult = "Size $intFileSize $strFileSizeIndicator ($strExt)";
		return( $strResult );
	}
?>
