hiding/showing specific column according to permission - php

Question

I need to hide/show action columns based on permissions
if action column is null I want to hide action column, if action has data I want to show that data passes on backend side.
// my backend code php
$data = $this->userModal->userslist();
foreach($data as $d){
if(ChechPermission($this->session->userdata('permissions'), "users", "edit")) {
$d->actions ='
<i class="fas fa-pen-square"></i>
';
} else {
$d->actions = '';
}
}
echo json_encode($data);
// end backend code php
// my datatable
$(document).ready(function(){
$("#userTable").dataTable({
pageLength: 25,
lengthMenu: [25, 50, 75, 100],
"dom": '<"top"lfB>rt<"bottom"p><"clear">',
buttons: [
'copy', 'excel', 'pdf', 'print'
],
'ajax' : {'url' : 'Users/getusers' , dataSrc : ""},
columns : [
{data : 'firstname'},
{data : 'middlename'},
{data : 'lastname'},
{data : 'username'},
{data : 'mobileno'},
{data : 'statusname'},
{data : 'groupname'},
{data : 'actions'}
]
});
});
my expected code in the datatable is a condition that filters action column data

Answer 1

Hi Abdir Abdirahim Ali,
There is a visible property which accept boolean.
https://datatables.net/reference/option/columns.visible
Here is a example for you.
Your frontend:
let showActionColumn= "<?= $showActionColumn ?>";
columns : [
{data : 'firstname'},
{data : 'middlename'},
{data : 'lastname'},
{data : 'username'},
{data : 'mobileno'},
{data : 'statusname'},
{data : 'groupname'},
{data : 'actions', visible : showActionColumn}
]
Your backend:
$data['showActionColumn'] = ChechPermission($this->session->userdata('permissions'), "users", "edit")

Answer 2

Using columnDefs can be useful for your case :
$('#userTable').DataTable({
pageLength: 25,
lengthMenu: [25, 50, 75, 100],
"dom": '<"top"lfB>rt<"bottom"p><"clear">',
buttons: [
'copy', 'excel', 'pdf', 'print'
],
'ajax' : {'url' : 'Users/getusers' , dataSrc : ""},
columns : [
{data : 'firstname'},
{data : 'middlename'},
{data : 'lastname'},
{data : 'username'},
{data : 'mobileno'},
{data : 'statusname'},
{data : 'groupname'},
{data : 'actions'}
],
columnDefs: [
{
targets: 7, // column assigned in the html table
"render": function(data, type, row) {
let _data = '';
if (row['actions'] != '') {
_data = row['actions'] ;
}
return _data;
}
},
]
});
