| ===hasPermission()===
| |
| Check to see if a user has permission for a given role/task whatever @param string $permissions The permisisions string. Example: "role(admin) or task(can_view_page) or task(can_edit_page)" Exmaple: "role(admin|staff)" is the same as "role(admin,staff)" which is the same as "role(admin) role(staff)" which is the same as "role(admin) | role(staff)" which is the same as "role(admin) or role(staff)" Example: "role(admin) or task(can_view_page) and role(staff)" is the same as "(role(admin) or task(can_view_page)) and role(staff)" i.e. parenthesis are grouped left. Note: You may reference variables, which is really template data, as a function argument or in a double quoted string. When referencing varaibles, you are allowed to include types, such as ${T1}z, but you are not allowed to do so in a doulbe quoted string. Variable names may consit of alpha-numeric character, '_', and '-'. You may protect a variable by surrounding it in {}'s Example: "func1($a,"x$a", '\' "' "x{$a}y" , "x{$ay} ${T1}z )" causes the (possbily fuzzy) method hasPermission_func1() with the following arguments: array( $this->template->getDisplayData('a',$node), 'x' . $this->template->getDisplayData('a',$node), '\' "', 'x' . $this->template->getDisplayData('ay',$node) , 'x' . $this->template->getDisplayData('a',$node) . 'y', 'x' . $this->template->getData('T1',z,$node,true,true)) There are special argument you can pass to the function which are <TEMPLATE>, <USER> and <NODE> which will be the template, user and calling node associated with this permission. Note: spaces provide an implicit comma to split arguments. Example functions: role, task which take a list or roles and task repsectively. Example function: form('person' method <USER>) -- finds the person form,relative to $node and calls $form->method(array($user)) Example function: form(person , 'weird method;',<USER>10) -- finds the person form,relative to $node and calls $form->$method(array($user,10)) where $method='weird method;' Example function: module('mod_name',method,arg1,...,argn) works like form but for modules
