getting the value from data table with checkbox codeigniter - php

Question

I am working with my project in school. How can i get the value of selected checkbox in data table. I am using a codeigniter framework and i am populating my data table in controller and passed it to the view. Now i want to something alert/output the user_id of the checked data table. What i really want is to save the values of the checked user_id in my database table.
Here is my controller for populating the data table:
public function getalldocs()
$listdocs = $this->Admin_model->getdoctors();
$data = array();
foreach ($listdocs as $docs) {
$row = array();
$row[] = $docs->user_fname;
$row[] = $docs->user_mname;
$row[] = $docs->user_lname;
$row[] = '<input name="user_id[]" value=" "'.$docs->user_id.'" " type="checkbox">';
$data[] = $row;
}
$output = array(
"data" => $data,
);
echo json_encode($output);
}
in my view, here is the ajax for data table:
function show_docs() {
$("#dataTables-docs").dataTable().fnDestroy();
table = $('#dataTables-docs').DataTable({
"ajax": {
"url": "<?php echo site_url('admin_controls/getalldocs')?>",
"type": "POST",
},
responsive: true,
className: 'select-checkbox',
'bInfo': false,
'paging': false
});
}
$(document).ready(function() {
$('#dataTables-docs').dataTable();
show_docs();
});

You can get data from row table using this code:
$('#dataTables-docs tbody').on('click', 'input[type="checkbox"]', function(e){
var row = $(this).closest('tr');
var data = table.row(row).data();
var rowData = data[1];
alert(rowData);
});
Return the data of row selected from checkbox, if you want get the value of checkbox (user_id), then you can use this code:
$('#dataTables-docs tbody').on('click', 'input[type="checkbox"]', function(e){
var user_id = $(this).val();
alert(user_id);
});
