RE: [PEAR] re: TreeMenu and Recursive algorithms

It seems to me that there is some sort of bug in TreeMenu.php when using the createFromStructure($params) function and passing the $params['nodeOptions'] for use with HTML_TreeNode( $data , $events ) so I am guessing there is something up with the splitting of the $params[] array into the $data[], $events[] arrays I just can't seem to figure it out the options thing has me really confused now! Even if this would work that would fix adding the links to each node and the folder icons, but I still would need a way to pass each category id from the original tree options to the nodeOptions. Slight change still same result :) snip-- / Tree $icon = "folder.gif"; $expanded_icon = "folder-expanded.gif"; $options = array('table' => 'categories', 'order' => 'category', 'columnNameMaps' => array('parentId' => 'predcessor', 'name' => 'category')); $tree = Tree::setupMemory('DBsimple', $dsn, $options); $tree->setup(); $node_options = array('text' => '', 'link' => "editCategory.php?id=", 'icon' => $icon, 'expandedIcon' => $expanded_icon); $_treeMenu = HTML_TreeMenu::createFromStructure(array('structure' => $tree, 'type' => 'kriesing', 'nodeOptions' = $node_options)); $treeMenu = new HTML_TreeMenu_DHTML($_treeMenu, array('images' => 'images/tree/', 'defaultClass' => 'text')); --snip I suspect I may just be doing it all wrong, but that wouldnt be the first time :) Hope this makes some sense, well nearly time to knock off so I will have to leave it until Monday, have a great weekend all :) Regards, Joseph Blythe -----Original Message----- From: Joseph Blythe [mailto:joseph@optcom.net.au] Sent: Friday, 11 April 2003 10:18 AM To: 'Wolfram Kriesing'; jeroen@terena.nl Cc: pear-general@lists.php.net Subject: RE: [PEAR] re: TreeMenu and Recursive algorithms Thankyou guys :) I basically have it working but still having problems with the folder icons and am getting a reapeating error message: "Notice: Undefined index: text in /usr/local/Zend/lib/php/HTML/TreeMenu.php on line 165", also how would I specify a link for each node which needs to pass the categorories id via the url ?

Yes, exactly. you can see http://cvs.php.net/co.php/pear/Tree/docs/Memory_DBsimple.php?r=1.2 for an example how to read the tree it should work somehow like this: $options = array( 'table' => 'myTree', 'order' => 'id', 'columnNameMaps'=>array( 'parentId' => 'predcessor' 'name' => 'category') ); $tree = Tree::setupMemory('DBsimple',// use the simple DB schema 'mysql://root@localhost/test', // the DSN $options); $tree->setup(); // and now import it into HTML_TreeMenu $icon = 'folder.gif'; $options = array('images'=>'/path/to/images'); $_treeMenu = HTML_TreeMenu::createFromStructure( array( 'structure'=>$tree, // this is really ugly, Richy // i could kick ur ass for that :-) // but it works 'type'=>'kriesing' ) ); $treeMenu = new HTML_TreeMenu_DHTML($_treeMenu,$options); i have not tried it, but it should work .... so you wont need recursion, etc. have fun -- Wolfram ... opensource @ vision:produktion ... http://opensource.visionp.de ... translating template engine .... http://sf.net/projects/simpletpl ... authentication system .... http://sf.net/projects/auth -- PEAR General Mailing List (http://pear.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
