Detailed Description

This class provides processing control methods.

A global instance is available via variable $ilCtrl

xml_style parameters: This mode was activated per default in the past, is now set to false but still being used and needed, if link information is passed to the xslt processing e.g. in content pages.

getNodeIdForTargetClass()

ilCtrl::getNodeIdForTargetClass (   $a_par_node,   $a_class,   $a_check = false  )

private

Searches a node for a given class ($a_class) "near" another node ($a_par_node).

It first looks if the given class is a child class of the current node. If such a child node has been found, its id is returned.

If not, this method determines, whether the given class is a sibling of the current node within the call structure. If this is the case, then the corresponding id is returned.

At last the method searches for the given class along the path from the current node to the root class of the call structure.

Parameters

string	$a_par_node	id of starting node for the search
string	$a_class	class that should be searched
bool	$a_check

Returns

array|bool id of target node that has been found

Exceptions

ilCtrlException

ilCtrl::saveParameter	(		$a_obj,

Set parameters that should be passed in every form and link of a gui class.

All links that relate to the specified gui object class and are build e.g. by using getLinkTarger() or getFormAction() will include this parameter. This is the mechanism to add url parameters to the standard url target everytime.

A typical example is the "ref_id" that should be included in almost every link or form action url. So the constructor of ilRepositoryGUI includes the command:

$this->ctrl->saveParameter($this, array("ref_id"));

Parameters

object	$a_obj	gui object that will process the parameter
mixed	$a_parameter	parameter name (string) or array of parameter names

setParameter()

ilCtrl::setParameter	(		$a_obj,

Set parameters that should be passed a form and link of a gui class.

All links that relate to the specified gui object class and are build e.g. by using getLinkTarger() or getFormAction() will include this parameter. This is the mechanism to add url parameters to the standard url target. The difference to the saveParameter() method is, that setParameter() does not simply forward the url parameter of the last request. You can set a spefific value.

If this parameter is also a "saved parameter" (set by saveParameter() method) the saved value will be overwritten.

The method is usually used in conjunction with a getFormAction() or getLinkTarget() call. E.g.:

    $this->ctrl->setParameter($this, "obj_id", $data_row["obj_id"]);
    $obj_link = $this->ctrl->getLinkTarget($this, "view");
