Datatables Checkboxes select multiple on matching ids

Question

I have a server-side datatable setup with the checkboxes plugin. Each checkbox has the data of a product_id.

var table = $('#display_users').DataTable( {
        "processing": true,
        "serverSide": true,
        'ajax': '{{ route ('/getUsers') }}',
        'columns' : [
            {"data" : "product_id"},
            {"data" : "product_id"},
            {"data" : "first_name"},
            {"data" : "last_name"},
            {"data" : "email"},
            {"data" : "company"},
            {"data" : "department"},
            {"data" : "created_at"}
        ],
        'columnDefs': [
            {
                'targets': 0,
                'checkboxes': {
                    'selectRow': true
                },

I would like to be able to, when a checkbox is selected, select all the checkboxes with the same product_id. This is only necessary for the records on the currently selected page. It seems this should be possible with the checkboxes select api, however I haven't been successful so far

I don't see much value in 'checkbox' plug-in as its features can be effortlessly implemented with few lines of code while giving you greater flexibility.

However, you don't really need to dig deep into 'checkbox' plug-in internals as your required feature can be easily coded with native DataTables API:

//listen for the clicking first column checkboxes
$('#display_users').click('tbody td:eq(0) [type="checkbox"]', function(){
  //grab current checkbox state and criteria to match (product_id) from the row data
  const state = $(event.target).prop('checked');
  const productId = dataTable.row($(event.target).closest('tr')).data().product_id;
  //iterate through current page rows and adjust checkboxes upon matching product_id
  dataTable.rows({page:'current'}).every(function(){
    if(this.data().product_id == productId) $(this.node()).find('td:eq(0) [type="checkbox"]').prop('checked', state);
  });
});

Complete demo of this concept you may find below:

//data sample
const srcData = [
  {product_id: 7, first_name: 'Nick', last_name: 'Furry', company: 'Avengers Inc'},
  {product_id: 7, first_name: 'Steve', last_name: 'Rogers', company: 'Avengers Inc'},
  {product_id: 4, first_name: 'Arthur', last_name: 'Curry', company: 'Justice Ltd'},
  {product_id: 4, first_name: 'Clark', last_name: 'Kent', company: 'Justice Ltd'},
  {product_id: 4, first_name: 'Barry', last_name: 'Allen', company: 'Justice Ltd'}
];

//datatable initialization
const dataTable = $('#display_users').DataTable({
  dom: 't',
  order: [1, 'asc'],
  data: srcData,
  columns: [null, ...Object.keys(srcData[0])].map(header => ({title: header || '', data: header})),
  columnDefs: [
    {targets: 0, orderable: false, render: () => '<input type="checkbox"></input>'}
  ]
});

//essential part - row checkbox click hander
$('#display_users').click('tbody td:eq(0) [type="checkbox"]', function(){
  //grab current checkbox state and criteria to match (product_id)
  const state = $(event.target).prop('checked');
  const productId = dataTable.row($(event.target).closest('tr')).data().product_id;
  //iterate through current page rows and adjust checkboxes upon matching product_id
  dataTable.rows({page:'current'}).every(function(){
    if(this.data().product_id == productId) $(this.node()).find('td:eq(0) [type="checkbox"]').prop('checked', state);
  });
});
