Typo3 Extensions programmieren - Snippets

Templates

Template Code holen

    function getTemplateCode($mySubpart){
        $tsTemplateFile = $this->conf['templateFile'];
        // Wenn Flextemplate dann code aus diesem, sonst aus TS
	$this->flexConf['template'] ? $templateCode = this->cObj->fileResource("uploads/tx_".$this->extKey."/".$this->flexConf['template']) : $templateCode=$this->cObj->fileResource($tsTemplateFile);
        return $templateCode;
    }

Saubere Links in Extensions erzeugen

Kommentar von Elmar Hinz:

Die Linkfunktionen der tslib_pibase sind nicht garade eine Hilfe. 2/3 davon streichen und die Extension wird 1/3 besser. Wenn Du Dich allein auf die Funktion pi_linkTP_keepPIvars konzentrierst, kannst du damit aber fast alles stemmen. Noch konsequenter wendest du gleich selbst die zugrundeliegende typolink Funktion an.

Session Variable in Typo3

Session Variablen kann man folgendermaßen spreichern.

 $GLOBALS["TSFE"]->fe_user->setKey("ses","$data", "$zustand");
 $GLOBALS["TSFE"]->fe_user->storeSessionData();

14.1. Storing user-data or session-data

Userdata => Eingeloggter User. Kein Zugriff mehr wenn ausgeloggt.

Session data => Jeder User. Eingeloggt oder nicht. Daten sind an die "browsing-session" gebunden und nicht an die user-id. Bleibt erhalten bis der Browser geschlossen wird.

Default expire-time of 24 hours.

Funktionen

$GLOBALS["TSFE"]->fe_user->getKey(type, key)

"type" is either "user" or "ses", which defines the data-space, user-data or session-data

"key" is the "name" under which your data is stored. This may be arrays or normal scalars.

Note that the key "recs" is reserved for the built-in "shopping-basket". As is "sys" (for TYPO3 standard modules and code)

Example:

if ($GLOBALS["TSFE"]->loginUser){
    $myData = $GLOBALS["TSFE"]->fe_user->getKey("user","myData");
} else {
    $myData = $GLOBALS["TSFE"]->fe_user->getKey("ses","myData");
}

This gets the stored data with the key "myData" from the user-data, but if no user is logged in, it's fetched from the session data instead.

$GLOBALS["TSFE"]->fe_user->setKey(type, key, data)

"type" is either "user" or "ses", which defines the data-space, user-data or session-data

"key" is the "name" under which your data is stored.

Note that the key "recs" is reserved for the built-in "shopping-basket". As is "sys" (for TYPO3 standard modules and code)

"data" is the variable, you want to store. This may be arrays or normal scalars.

Example:

$myConfig["name"] = "paul";
$myConfig["address"] = "Main street";
$GLOBALS["TSFE"]->fe_user->setKey("ses","myData", $myConfig);

This stores the array $myConfig under the key "myData" in the session-data. This lasts as long as "paul" is surfing the site!
