& addItem | ( | &$ | node | ) |
This function adds an item to the the tree.

createFromStructure | ( | $ | params | ) |
Import method for creating HTML_TreeMenu objects/structures out of existing tree objects/structures. Currently supported are Wolfram Kriesings' PEAR Tree class, and Richard Heyes' (me!) Tree class (available here: http://www.phpguru.org/). This method is intended to be used statically, eg: $treeMenu = &HTML_TreeMenu::createFromStructure($myTreeStructureObj);
array | $params | An array of parameters that determine how the import happens. This can consist of: structure => The tree structure type => The type of the structure, currently can be either 'heyes' or 'kriesing' nodeOptions => Default options for each node |
Wolfram Kriesings' PEAR Tree class
Richard Heyes' (me!) second (array based) Tree class
Richard Heyes' (me!) original OO based Tree class

createFromXML | ( | $ | xml | ) |
Creates a treeMenu from XML. The structure of your XML should be like so:
<treemenu> <node text="First node" icon="folder.gif" expandedicon="folder-expanded.gif"> <node text="Second node" icon="folder.gif" expandedicon="folder-expanded.gif"> <node text="Sub node" icon="folder.gif" expandedicon="folder-expanded.gif"> </node> <node text="Third node" icon="folder.gif" expandedicon="folder-expanded.gif"> </treemenu>
Any of the options you can supply to the HTML_TreeNode constructor can be supplied as attributes to the <node> tag. If there are no subnodes for a particular node, you can use the XML shortcut <node ... /> instead of <node ... ></node>. The $xml argument can be either the XML as a string, or an pre-created XML_Tree object. Also, this method REQUIRES my own Tree class to work (http://phpguru.org/tree.html). If this has not been include()ed or require()ed this method will die().
mixed | $xml | This can be either a string containing the XML, or an XML_Tree object (the PEAR::XML_Tree package). |
