View Full Version : Passing all nodes in a GridTree back to a PHP script

15 Jan 2011, 3:19 PM
Hi all,

I hope someone can help, I've been trying to create a save function for an Ext.ux.TreeGrid with no luck. Currently I have a save button that sends an AJAX request to a PHP script, but I am finding it very difficult to send all of the data contained in the TreeGrid. I assume sending back a JSON array would be the most logical, but I haven't been able to do this.

I have seen elsewhere on the forums examples on how to save a tree, but they are not working for this.

Can anyone point me in the right direction?

What's the data format you want to use transmit the tree data?

The format that the data comes through to the server? Honestly I am quite easy on this. Passing an array with all of the data would be the easiest, but whatever it comes through as I can do the PHP to handle the rest.

Try something like:

function addNode(node, data) {
var attrs = Ext.apply({}, node.attributes);
if (node.hasChildNodes()) {
attrs.children = [];
for (var i = 0; i < node.childNodes.length; i++) {
addNode(node.childNodes[i], attrs.children);
return data;
var data = addNode(tree.getRootNode(), []);

Thanks, I actually just had some success as well, finally!

I found a thread that covers the use of a JsonTreeSerializer. By using that I was actually able to pass the full JSON array back to PHP and decode it from that side.

Thanks for all the help!
