Generate a jstree using json response zend php - php

Question

In the model:
public function groups($getGroupId) {
$cols = array('group_id','name');
$sql = $this->select ()
->from ( $this->_name, $cols )
->where ( 'parent_id=?', $getGroupId );
$groupDetails = $this->fetchAll ( $sql );
//$childGroupName = $groupDetails['name'];
return $groupDetails->toArray();
}
groupDetails.php page:
$dbGroup = new dbGroups();
$groupDetails = $dbGroup -> groups($getGroupId);
$jsonResponse = json_encode($groupDetails);
When printing the jsonResonse (print_r($jsonResponse)). I'm getting response like this
[{"group_id":"2","name":"ABCD"},{"group_id":"7","name":"XYZ"}]
how to generate a jstree using json response
By jstree demo i written a code like this for getting tree structure but i am unable to get a tree.
Please help me
jQuery(document).ready(function(){
//alert("get tree view");
jQuery("#treeView").jstree({
// This example uses JSON as it is most common
"json_data" : {
// This tree is ajax enabled - as this is most common, and maybe a bit more complex
// All the options are almost the same as jQuery's AJAX (read the docs)
"ajax" : {
// the URL to fetch the data
"url" : "groupDetails.php",
// the `data` function is executed in the instance's scope
// the parameter is the node being loaded
// (may be -1, 0, or undefined when loading the root nodes)
"data" : function (n) {
// the result is fed to the AJAX request `data` option
return {
"operation" : "get_children",
"id" : n.attr ? n.attr("id").replace("node_","") : 1
};
}
}
},
"ui" : {
"select_limit" : 1
},
"themes" : {
"theme" : "default",
"dots" : true,
"icons" : true
},
"types" : {
// I set both options to -2, as I do not need depth and children count checking
// Those two checks may slow jstree a lot, so use only when needed
"max_depth" : -2,
"max_children" : -2,
// I want only `drive` nodes to be root nodes
// This will prevent moving or creating any other type as a root node
"valid_children" : [ "drive" ],
"types" : {
// The default type
"default" : {
// I want this type to have no children (so only leaf nodes)
// In my case - those are files
"valid_children" : "none",
// If we specify an icon for the default type it WILL OVERRIDE the theme icons
"icon" : {
"image" : "./file.png"
}
},
// The `folder` type
"folder" : {
// can have files and other folders inside of it, but NOT `drive` nodes
"valid_children" : [ "default", "folder" ],
"icon" : {
"image" : "./folder.png"
}
},
// The `drive` nodes
"drive" : {
// can have files and folders inside, but NOT other `drive` nodes
"valid_children" : [ "default", "folder" ],
"icon" : {
"image" : "./root.png"
},
// those prevent the functions with the same name to be used on `drive` nodes
// internally the `before` event is used
"start_drag" : false,
"move_node" : false,
"delete_node" : false,
"remove" : false
}
}
},
"plugins" : ["themes","json_data","ui","crrm","cookies","dnd","search","types","hotkeys","contextmenu" ]
})
});

Your json should look like this:
[
{
"data" : {
"icon" : <optional>,
"title" : <node name>
},
"attr" : {
"rel" : <the type you defined in the js (maybe "group")>,
"title" : <node title>,
"id" : <the node's id / group id>
},
"state" : "closed"
}
]
You can put anything you want at the "attr" hash, basically it can hold other information you might need.
