Hi
I am working in PHP.I have tree view which is made with database. The database for this tree has a PARENT CHILD relation based in id. I have to give the user an option of adding new nodes at different tree levels. For that i am using textfields in the tree where ever the insertion of new node is possible. The question is that how can i come to know that which text field has which parent so that i can save its value, which will ba string, against its parent id....

ne suggestion, comment....

Regards

Well, either you or the user needs to specify where this new item will be attached - you can't just figure it out by magic. Perhaps a pop-up that lists all nodes so that they can select what it is attached to?

My choice would be that if they want to modify the tree, each element on the tree has a button (or a series of buttons).

[+] Add Node
[-] Remove Node (only if end of tree)
[--] Remove Node and all sub nodes
[Up] Move the node above the previous node at the same level
[Down] Move the node below the next node at the same level
[Left] Move the node up 1 level.
[Right] Move the node down 1 level as a child of the node above.
[Edit] Alter this nodes properties.

That sort of thing.

Now, admittedly, this may look a little messy.

But each button's url would be something like ...

/amendtree.php?id=ThisNodesID&parentid=ThisNodesParentID


So, as part of the rendering you can create the urls for the images on the fly as you render the node iteself.

Are you using a proper tree class? One which says find this node or find path to this node,etc.

If so, I'd like to see it. I have a tree class which allows out of sequence addition. This means I can read data which is in the format of

nodeid, parentid, data

and then add it to the tree.

The tree sorts out the heirarchy at render time.

I don't have to add the data into the tree top down.

It also means that I only need to make 1 call to the database to retrieve all the nodes.

I'd very much like to see this working? Especially if you create a generic class or need any further help.
