Member Function Documentation

t3lib_basicFileFunctions::init ( mounts,

Constructor This function should be called to initialise the internal arrays $this->mounts and $this->f_ext

A typical example of the array $mounts is this: $mounts[xx][path] = (..a mounted path..) the 'xx'-keys is just numerical from zero. There are also a [name] and [type] value that just denotes the mountname and type. Not used for athentication here. $this->mounts is traversed in the function checkPathAgainstMounts($thePath), and it is checked that $thePath is actually below one of the mount-paths The mountpaths are with a trailing '/'. $thePath must be with a trailing '/' also! As you can see, $this->mounts is very critical! This is the array that decides where the user will be allowed to copy files!! Typically the global var $WEBMOUNTS would be passed along as $mounts

A typical example of the array $f_ext is this: $f_ext['webspace']['allow']=''; $f_ext['webspace']['deny']='php3,php'; $f_ext['ftpspace']['allow']='*'; $f_ext['ftpspace']['deny']=''; The control of fileextensions goes in two catagories. Webspace and Ftpspace. Webspace is folders accessible from a webbrowser (below TYPO3_DOCUMENT_ROOT) and ftpspace is everything else. The control is done like this: If an extension matches 'allow' then the check returns true. If not and an extension matches 'deny' then the check return false. If no match at all, returns true. You list extensions comma-separated. If the value is a '*' every extension is allowed The list is case-insensitive when used in this class (see init()) Typically TYPO3_CONF_VARS['BE']['fileExtensions'] would be passed along as $f_ext.

Example: $basicff->init($GLOBALS['FILEMOUNTS'],$TYPO3_CONF_VARS['BE']['fileExtensions']);

array Contains the paths of the file mounts for the current BE user. Normally $GLOBALS['FILEMOUNTS'] is passed. This variable is set during backend user initialization; $FILEMOUNTS = $BE_USER->returnFilemounts(); (see typo3/init.php)
array Array with information about allowed and denied file extensions. Typically passed: $TYPO3_CONF_VARS['BE']['fileExtensions']

Returns the destination path/filename of a unique filename/foldername in that path. If $theFile exists in $theDest (directory) the file have numbers appended up to $this->maxNumber. Hereafter a unique string will be appended. This function is used by fx. TCEmain when files are attached to records and needs to be uniquely named in the uploads/* folders

string The directory for which to return a unique filename for $theFile. $theDest MUST be a valid directory. Should be absolute.
boolean If set the filename is returned with the path prepended without checking whether it already existed!
string The destination absolute filepath (not just the name!) of a unique filename/foldername in that path.
