t3lib_pageSelect::checkRecord	(	$	table,
		$	uid,
		$	checkPage = 0
	)

Checks if a record exists and is accessible. The row is returned if everything's OK.

Parameter:

	string	The table name to search
	integer	The uid to look up in $table
	boolean	If checkPage is set, it's also required that the page on which the record resides is accessible

Rückgabe:

mixed Returns array (the record) if OK, otherwise blank/0 (zero)

t3lib_pageSelect::checkWorkspaceAccess

(

$

wsid

)

Checks if user has access to workspace.

Parameter:

int

$wsid Workspace ID

Rückgabe:

boolean true if has access

enableFields()

t3lib_pageSelect::enableFields	(	$	table,
		$	show_hidden = -1,
		$	ignore_array = array(),
		$	noVersionPreview = FALSE
	)

Returns a part of a WHERE clause which will filter out records with start/end times or hidden/fe_groups fields set to values that should de-select them according to the current time, preview settings or user login. Definitely a frontend function. Is using the $TCA arrays "ctrl" part where the key "enablefields" determines for each table which of these features applies to that table.

Parameter:

	string	Table name found in the $TCA array
	integer	If $show_hidden is set (0/1), any hidden-fields in records are ignored. NOTICE: If you call this function, consider what to do with the show_hidden parameter. Maybe it should be set? See tslib_cObj->enableFields where it's implemented correctly.
	array	Array you can pass where keys can be "disabled", "starttime", "endtime", "fe_group" (keys from "enablefields" in TCA) and if set they will make sure that part of the clause is not added. Thus disables the specific part of the clause. For previewing etc.
	boolean	If set, enableFields will be applied regardless of any versioning preview settings which might otherwise disable enableFields

Rückgabe:

string The clause starting like " AND ...=... AND ...=..."

t3lib_pageSelect::fixVersioningPid	(	$	table,
		&$	rr
	)

Finding online PID for offline version record ONLY active when backend user is previewing records. MUST NEVER affect a site served which is not previewed by backend users!!! Will look if the "pid" value of the input record is -1 (it is an offline version) and if the table supports versioning; if so, it will translate the -1 PID into the PID of the original record Used whenever you are tracking something back, like making the root line. Principle; Record offline! => Find online?

Parameter:

	string	Table name
	array	Record array passed by reference. As minimum, "pid" and "uid" fields must exist! "t3ver_oid" and "t3ver_wsid" is nice and will save you a DB query.

Rückgabe:

void (Passed by ref).

	string	Path for the current script in domain. Eg. "/somedir/subdir". Typ. supplied by t3lib_div::getIndpEnv('SCRIPT_NAME')
	string	Request URI: Used to get parameters from if they should be appended. Typ. supplied by t3lib_div::getIndpEnv('REQUEST_URI')

Rückgabe:

mixed If found, returns integer with page UID where found. Otherwise blank. Might exit if location-header is sent, see description.

		$	expTime = 0
	)

Returns string value stored for the hash string in the table "cache_hash" Can be used to retrieved a cached value Can be used from your frontend plugins if you like. It is also used to store the parsed TypoScript template structures. You can call it directly like t3lib_pageSelect::getHash()

Parameter:

	string	The hash-string which was used to store the data value
	integer	Allowed expiretime in seconds. Basically a record is selected only if it is not older than this value in seconds. If expTime is not set, the hashed value will never expire.

t3lib_pageSelect::getRootLine	(	$	uid,
		$	MP = '',
		$	ignoreMPerrors = false
	)

Returns array with fields of the pages from here ($uid) and back to the root NOTICE: This function only takes deleted pages into account! So hidden, starttime and endtime restricted pages are included no matter what. Further: If any "recycler" page is found (doktype=255) then it will also block for the rootline) If you want more fields in the rootline records than default such can be added by listing them in $GLOBALS['TYPO3_CONF_VARS']['FE']['addRootLineFields']

Parameter:

	integer	The page uid for which to seek back to the page tree root.
	string	Commalist of MountPoint parameters, eg. "1-2,3-4" etc. Normally this value comes from the GET var, MP
	boolean	If set, some errors related to Mount Points in root line are ignored.

Rückgabe:

array Array with page records from the root line as values. The array is ordered with the outer records first and root record in the bottom. The keys are numeric but in reverse order. So if you traverse/sort the array by the numeric keys order you will get the order from root and out. If an error is found (like eternal looping or invalid mountpoint) it will return an empty array.

Returns FALSE if not in workspace or no versioning for record. Notice, that the enablefields of the online record is also tested.

t3lib_pageSelect::movePlhOL	(	$	table,

Parameter:

	string	Table name
	array	Row (passed by reference) - only online records...

Parameter:

	string	32 bit hash string (eg. a md5 hash of a serialized array identifying the data being stored)
	string	The data string. If you want to store an array, then just serialize it first.
	string	$ident is just a textual identification in order to inform about the content! May be 20 characters long.

tslib_TStemplate::start(), getHash()

t3lib_pageSelect::versionOL	(	$	table,
		&$	row,
		$	unsetMovePointers = FALSE,
		$	bypassEnableFieldsCheck = FALSE
	)

Versioning Preview Overlay ONLY active when backend user is previewing records. MUST NEVER affect a site served which is not previewed by backend users!!! Generally ALWAYS used when records are selected based on uid or pid. If records are selected on other fields than uid or pid (eg. "email = ....") then usage might produce undesired results and that should be evaluated on individual basis. Principle; Record online! => Find offline?

Parameter:

	string	Table name
	array	Record array passed by reference. As minimum, the "uid", "pid" and "t3ver_state" fields must exist! The record MAY be set to FALSE in which case the calling function should act as if the record is forbidden to access!
	boolean	If set, the $row is cleared in case it is a move-pointer. This is only for preview of moved records (to remove the record from the original location so it appears only in the new location)
	boolean	Unless this option is TRUE, the $row is unset if enablefields for BOTH the version AND the online record deselects it. This is because when versionOL() is called it is assumed that the online record is already selected with no regards to it's enablefields. However, after looking for a new version the online record enablefields must ALSO be evaluated of course. This is done all by this function!

Rückgabe:

void (Passed by ref).
