I got huge response from my previous article How to Create Dynamic Tree View Menu,Most of readers asking about how to use checkbox with this and drag and drop features,so In this article i am creating dynamic tree menu with check box using jstree jquery tree view plugin,php and mysql. Dynamic means all nodes of tree menu is depend upon server side processing.
I am using same database structure like previous tutorial How to Create Dynamic Tree View Menu,

How To create Dynamic Tree using PHP, MySQL and jquery
So we are using below files to create dynamic treeview using jstree jquery tree plugin,php and mysql. Its very easy and simple,The project structure are follows:
- dist folder : This folder will contains all
js/cssand images files. - index.php : This file is use to display tree menu.
- response.php : This file is use to fetch tree nodes from database and convert them into json object.
Step 1: Create Table structure to stored tree menu nodes.we need to create ‘test’ database(if you have then don’t need) and created below 'treeview_items' table into this database.
1 2 3 4 5 6 | CREATE TABLE IF NOT EXISTS `treeview_items` ( `id` int(11) NOT NULL, `name` varchar(200) NOT NULL, `text` varchar(200) NOT NULL, `parent_id` varchar(11) NOT NULL ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=latin1; |
Step 2: Created connection with MySQL into (response.php) file.
1 2 3 4 5 6 7 8 9 10 11 | servername = "localhost"; $username = "root"; $password = ""; $dbname = "test"; $conn = mysqli_connect($servername, $username, $password, $dbname) or die("Connection failed: " . mysqli_connect_error()); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } |
Step 3: Created PHP array of all tree nodes and encode into json(response.php) file.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | $sql = "SELECT * FROM `treeview_items` "; $res = mysqli_query($conn, $sql) or die("database error:". mysqli_error($conn)); //iterate on results row and create new index array of data while( $row = mysqli_fetch_assoc($res) ) { $data[] = $row; } $itemsByReference = array(); // Build array of item references: foreach($data as $key => &$item) { $itemsByReference[$item['id']] = &$item; // Children array: $itemsByReference[$item['id']]['children'] = array(); // Empty data class (so that json_encode adds "data: {}" ) $itemsByReference[$item['id']]['data'] = new StdClass(); } // Set items as children of the relevant parent item. foreach($data as $key => &$item) if($item['parent_id'] && isset($itemsByReference[$item['parent_id']])) $itemsByReference [$item['parent_id']]['children'][] = &$item; // Remove items that were added to parents elsewhere: foreach($data as $key => &$item) { if($item['parent_id'] && isset($itemsByReference[$item['parent_id']])) unset($data[$key]); } // Encode: echo json_encode($data); |
Step 4: Included all js/css files of jsTree into index.php file.
1 2 3 4 | <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.0/css/bootstrap.min.css"> <script type="text/javascript" charset="utf8" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.8.2.min.js"></script> <link rel="stylesheet" href="dist/style.min.css" /> <script src="dist/jstree.min.js"></script> |
Step 5: Created tree menu container in index.php.
1 | <div id="tree-container"></div> |
Step 6: Call jstree method on div container.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | <script type="text/javascript"> $(document).ready(function(){ //fill data to tree with AJAX call $('#tree-container').jstree({ 'plugins': ["wholerow", "checkbox"], 'core' : { 'data' : { "url" : "response.php", "plugins" : [ "wholerow", "checkbox" ], "dataType" : "json" // needed only if you do not supply JSON headers } } }) }); </script> |
You can see here, we are using "checkbox" plugin to create check-box against each node.We are passing json data to jstree method.

hi sir, I have used the code and its working fine. I have added a field as link which will hold the target for child nodes . On clicking the same it will redirect the same to that page. How to implement the same. Can anyone help.
Hi Rajessh,
I got some time to solve ur problem, You need to add below changes to add href in you all node anchor tag but on-click to ridrect you need to debugging on jstree call back function.
You can add href attribute and value using below code,
//already have in you code
$itemsByReference[$item[‘id’]][‘data’] = new StdClass();
add below two lines
$itemsByReference[$item[‘id’]][‘a_attr’] = new StdClass();
$itemsByReference[$item[‘id’]][‘a_attr’]->href = ‘google.com’;
thanks sir for ur reply. Can anyone help in debugging the jstree call back fucntion
sure, i ll share jstree call back fucntion.
you can add this code with jstree to redirect on href page.
jstree().bind(“select_node.jstree”, function (e, data) {
var href = data.node.a_attr.href;
document.location.href = href;
//console.log(href);
})

Hi how can i add grid.
Eg.
Node price
item1 342
item2 333
like this
you can change node text value using mysql text field.
I copied all the snippets into right php files but have no output… 🙁 the code is not working… it is not something outdated due new version of jsTree ???
The hard-coded data works well, also the code from article “How to Create Dynamic Tree View Menu” – that I adapted on My custom database successfully, but this JSON is My nightmare… 🙁
i am using 3.2.1 stable version,have u compared JSON object of hardcoded and php generated,
Hello
How change database column name?
The colum must be “text”?
I did’t found “text” call funtion on response.php
Thanks
i used SELECT * FROM `treeview_items query,so i do not use column name
But if i change column name “text”, the data is not show.
How to fix this?
soryy actually jstree must have ‘text’ field json for node label name, so u need to change column name after select * query, so u will rebuild fetched mysql array data.
FIrst thanks for the tutorial. I don’t understand why you pass item as reference (not expert on PHP tricks), but well, I will study this. About the tutorial, I can’t get it working. I tried my own, and got an empty tree. Then I saw there is a sample download, but I get the same result. Some idea why? https://uploads.disquscdn.com/images/65a9bf823b87d807bac4a9bfd6b78cc56c3c4563380e893cfdee78dc0eab2ce0.png
Hi Giuseppe,
It took me some hours to find out since I’m not well versed in PHP and JSON, but it seems that the file outputs the keys in the JSON which messes up the structure (in your screenshot the first characters {“1”: for example). You can avoid this by changing the last line to:
echo json_encode(array_values($data));
For more information on array_values check: http://php.net/manual/en/function.array-values.php
How to add a file name under the tree which with a hyper link??
you can get info here,
https://www.phpflow.com/php/advanced-treeview-menu-using-jstree-with-php-and-mysql/
$sql = “SELECT id, title AS text, parent_id FROM my_table ;”
If for example in the DB the name of the column is “title”, in the returned array it’s aliased to “text”.
yes, its perfect
Hello,
Thanks for this tutorial. I have use this example with a
menu to set the authorisation. The response.php is working well in
combination with the database, the whole tree is build correctly. But
how can I, when the page just is build, set the checkboxes when the
pages is opening?
Can I do this in Response.php? But how? Or need
this the be done in jQuery after the full tree is build and set then the
checkboxes by there id?
Or did write it down already somewere, because it seems to me that I’m not the first one with question.
Thanks,
Nico
you can take reference from this jstree tutorial , https://www.phpflow.com/php/create-rename-delete-node-using-jstree-php-mysql/
Thank you very much ! This is exactly what i wanted. I was able to easily enter this modification into the code.
And lastly, to finish my app, i would like to be able to complete the script using the following 3 buttons « edit » « delete » and « view » wrote in the example, but by displaying a pop-up instead of a new web-page then add a general button that says « add ».
If you have a moment, kindly.
you need to remove context menu and add redirect logic to add page view on click of node href attribute.
