ilCtrl::getNodeIdForTargetClass (   $a_par_node,
  $a_class,

)

Searchs a node for a given class ($a_class) "near" the another node ($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 wether 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 methode searchs for the given class along the path from the current node to the root class of the call structure.

Parameters
stringid of starting node for the search
stringclass that should be searched
Returns
int id of target node that has been found

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 (which is set by the setTargetScript() method) 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_objgui object that will process the parameter

Set context of current user interface.

A context is a ILIAS repository object (obj ID + obj type) with an additional optional subobject (ID + Type)

Parameters
integerobject ID
stringobject type
integersubobject ID
stringsubobject type

ilCtrl::setParameter ( &  $a_obj,
  $a_parameter,
  $a_value 
)

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 (which is set by the setTargetScript() method) 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");
Parameters
object$a_objgui object
string$a_parameterparameter name
string$a_parameterparameter value

{
$this->parameter[strtolower(get_class($a_obj))][$a_parameter] = $a_value;
}
ilCtrl::setParameterByClass (   $a_class,
  $a_parameter,

Same as setParameterByClass, except that a class name is passed.

Parameters
string$a_classgui class name
string$a_parameterparameter name
string$a_parameterparameter value
