Export all data regardless of pagination in datatables - php

Question

Here is what I'm trying to do. I'm trying to export all of the data in a datatable regardless of the amount displayed on the page.
Based on the link: https://datatables.net/forums/discussion/48044/export-all-regardless-of-pagination
I tried to do the following:
but guess what I'm only able to export the csv file with only a certain amount of records.
var datatableFilters_{$this->id} = ".App_Json::encode($this->strictFilters).";
var datatablePassthru_{$this->id} = ".App_Json::encode($this->passthruVariables).";
$( document ).ready(function() {
var datatable = $('#{$this->id}').DataTable(
{
".(($this->allowExporting) ? "dom: 'Bfrtip', buttons: [ { extend:'copy',exportOptions: {modifier: {page: 'all', search: 'none' } }, }, { extend:'csv',exportOptions: {modifier: {page: 'all', search: 'none', serverSide: 'false' } }, }, { extend:'excel',exportOptions: {modifier: {page: 'all', search: 'none' } }, }, { extend:'pdf',exportOptions: {modifier: {page: 'all', search: 'none' } }, }, { extend:'print',exportOptions: {modifier: {page: 'all', search: 'none' } }, } ], " : '')."
".(($this->showRecordsPerPageAtBottom) ? "sDom: 'Rfrtlip'," : '')."
serverSide: true,
responsive: true,
pageLength: {$this->recordsPerPage},
searching: ".(($this->allowSearch) ? 'true' : 'false').",
paging: ".(($this->allowPagination) ? 'true' : 'false').",
ordering: ".(($this->allowSorting) ? 'true' : 'false').",
info: ".(($this->showRecordCount) ? 'true' : 'false').",
language: {
search: '_INPUT_',
searchPlaceholder: 'Search...'
},
$order
ajax: {
url: 'ajax.php',
type: 'POST',
data: function(d) {
d.ajaxAction = 'loadAjaxClassAction',
d.className = 'Browser_DataTable',
d.classFunction = 'ajaxProcess',
d.aryFunctionAttributes = jsonEncode([
'".get_called_class()."',
jsonEncode(datatableFilters_{$this->id}),
jsonEncode(datatablePassthru_{$this->id})
])
}
}
}
);
Is there a way to export all records?
