This example demonstrates Editor's ability to edit data multiple layers deep, which we term nested editing. Using the datatable field type we can use another Editor
instance to make the data in the field editable in exactly the same way we can for the host table.
In this case the list of options for the site is editable, letting options be created, edited or removed from the list as required without needing to leave the form for another page.
| First name | Last name | Phone # | Location |
|---|---|---|---|
| First name | Last name | Phone # | Location |
The Javascript shown below is used to initialise the table shown in this example:
var siteEditor = new DataTable.Editor({
ajax: '../../controllers/sitesNested.php',
fields: [
{
label: 'City:',
name: 'name'
},
{
label: 'Continent:',
name: 'continent',
type: 'datatable'
}
]
});
var editor = new DataTable.Editor({
ajax: '../../controllers/joinNested.php',
fields: [
{
label: 'First name:',
name: 'users.first_name'
},
{
label: 'Last name:',
name: 'users.last_name'
},
{
label: 'Phone #:',
name: 'users.phone'
},
{
label: 'Site:',
name: 'users.site',
type: 'datatable',
editor: siteEditor,
optionsPair: {
value: 'id'
},
config: {
ajax: '../../controllers/sitesNested.php',
buttons: [
{ extend: 'create', editor: siteEditor },
{ extend: 'edit', editor: siteEditor },
{ extend: 'remove', editor: siteEditor }
],
columns: [
{
title: 'Name',
data: 'name'
},
{
title: 'Continent',
data: 'continent'
}
]
}
}
],
table: '#example'
});
$('#example').DataTable({

type: 'POST'
},
buttons: [
{ extend: 'create', editor: editor },
{ extend: 'edit', editor: editor },
{ extend: 'remove', editor: editor }
],
columns: [

const siteEditor = new DataTable.Editor({

]
});
const editor = new DataTable.Editor({

],
columns: [

data: 'continent'
}
]
}
}
],
table: '#example'
});
new DataTable('#example', {
ajax: {

type: 'POST'
},
buttons: [
{ extend: 'create', editor },
{ extend: 'edit', editor },
{ extend: 'remove', editor }
],

In addition to the above code, the following Javascript library files are loaded for use in this example:
The HTML shown below is the raw HTML table element, before it has been enhanced by DataTables:
This example uses a little bit of additional CSS beyond what is loaded from the library files (below), in order to correctly display the table. The additional CSS used is shown below:
The following CSS library files are loaded for use in this example to provide the styling of the table:
This table loads data by Ajax. The latest data that has been loaded is shown below. This data will update automatically as any additional data is loaded.
The script used to perform the server-side processing for this table is shown below. Please note that this is just an example script using PHP. Server-side processing scripts can be written in any language, using the protocol described in the DataTables documentation.
