How can i render component that is sent from controller via an ajax request? For example i want to dynamically filter product using this method:
Load the index URL
Fetch the products based on the filter category or return all the products using ajax
My ajax Code:
$(document).ready(function () {
filterData();
// Filter data function
function filterData() {
// Initializing loader
$('#product-listing-row').html('<div id="loading" style="" ></div>');
var action = 'fetchData';
var subCategory = getFilter('sub-category');
/* LARAVEL META CSRF REQUIREMENT */
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
// Ajax Call
$.ajax({
url: "/shop/filter",
method: "POST",
data: {action: action, subCategory: subCategory},
success: function (data) {
$('#product-listing-row').html(data);
}
});
}
// Get Filter by class name function
function getFilter(className) {
var filter = [];
$('.' + className + ':checked').each(function () {
filter.push($(this).val());
});
//console.log(filter);
return filter;
}
$('.common-selector').click(function () {
filterData();
});
});
I am getting all the filters from ProductController
Instead of manually writing html in controller I want to return the specific component from the controller
ProductController:
public function productFilter() {
if (!request()->action) abort('500');
// Starting the query for products which are active
$products = Product::where('is_active', '1');
//dump(request()->subCategory);
/* Checking the filters */
// sub category exists
if (request()->subCategory) $products = $products->where('sub_category_id', request()->subCategory);
// Completing the query
$products = $products->orderBy('created_at', 'DESC')->paginate(15);
// Adding reviews and total review
$products = Product::setProductReviewTotalReviewsAttr($products);
foreach ($products as $product)
//view('components.shop-product', ['product' => $product])->render();
echo '<x-shop-product :product="$product"></x-shop-product>';
}
Instead of getting the components rendered, I am receiving the whole string echoed out. Is there any way i can just get the components rendered?
Thanks in advance
Actually now I found a way to do it myself
I applied the following to the ProductController
return View::make("components.shop-product")
->with("product", $product)
->render();
Updated Code:
public function productFilter() {
if (!request()->action) abort('500');
// Starting the query for products which are active
$products = Product::where('is_active', '1');
//dump(request()->subCategory);
/* Checking the filters */
// sub category exists
if (request()->subCategory) $products = $products->where('sub_category_id', request()->subCategory);
// Completing the query
$products = $products->orderBy('created_at', 'DESC')->paginate(15);
// Adding reviews and total review
$products = Product::setProductReviewTotalReviewsAttr($products);
$output = '';
foreach ($products as $product) {
$output .= View::make("components.shop-product")
->with("product", $product)
->render();
}
if (count($products) > 0)
echo $output;
else
echo '<div class="col">No Data</div>';
}
with laravel > 8 you can use \Blade::render directly in your controller to render even anonymouse components, here I'm rendering a table component with a lot of properties:
class componentController extends Controller {
public function index(){
$table = [
:tableid => "table"
:thead => ["id","name","job"]
:data => [
["1","marcoh","captain"],
["2","sanji","cook"]
],
tfoot => false
];
// Renders component table.blade.php
return \Blade::render('
<x-table
:tableid="$tableid"
:thead="$thead"
:data="$data"
tfoot
/>
', $table);

I'm Trying to Save The Product into The Database By Clicking On Add To Cart
But It's Not Adding I Also Use Ajax `
I Want To Add The Cart To DataBase And It's Not Adding.
This is The Error That I cant Add Any Product To The Cart Because Of It

javascript page.
This Is MY First Time To Use Ajax And Sure That Every Thing Is Correct I Want Know Why Its Not Add
$('.addToCartBtn').click(function (e) {
e.preventDefault();
var product_id = $(this).closest('.product_data').find('.prod_id').val();
var product_qty = $(this).closest('.product_data').find('.qty-input').val();
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$.ajax({
method: "POST",
url: "/add-to-cart",
data: {
'product_id': product_id,
'product_qty': product_qty,
},
success: function (response) {
alert(response.status);
}
});
// alert(product_id);
// alert(product_qty);
// // alert ("test ") ;
});
Route:
Route::middleware(['auth'])->group(function () {
Route::post('/add-to-cart', [App\Http\Controllers\User\indexController::class, 'addToCart' ]);});
So why this error occurs, how can I fix it?`
This look like an error in importation like App\Models\Cart not like this?
verify if you had added use App\Models\Cart;
I did a multiselect input dropdown using select2. However, I dont really sure how to fetch the data that I call from database in the dropdown so that I can view it in datatable. Here are my codes:
Script for input dropdown select2:
$('.ethnicity').select2({
placeholder: 'Select..',
ajax: {
url: '/select2-autocomplete-ajax_ethnicity',
dataType: 'json',
delay: 250,
processResults: function ($ethnicity) {
return {
results: $.map($ethnicity, function (item) {
return {
text: item.Bangsa_updated,
id: item.id,
}
})
};
Controller for input dropdown so it will select the input typed:
public function ethnicity(Request $request)
{
$ethnicity = [];
if($request->has('q')){
$search = $request->q;
$ethnicity = DB::table("user")
->select("id","ethnic")
->where('ethnic','LIKE',"%$search%")
->get();
}
return response()->json($ethnicity);
}
The above code only to select the data from database without fetch data to datatable.
The controller below to catch data into datatable (I used this for simple dropdown, however dont know how to change so it is useful for above input dropdown.
public function fnFilter(Request $request)
{
if(request()->ajax())
{
if(!empty($request->dataGender))
{
$data = DB::table('user')
->select('id', 'Fn', 'Ln')
->where('ethnic', $request->ethnicity)
->get();
}
else
{
$data = DB::table('user')
->select('id', 'Fn', 'Ln', 'Umur', 'Phone', 'Dob','St', 'Country','Zip','Ct','Jantina')
->get();
}
return datatables()->of($data)->make(true);
}
$dataName = DB::table('modified_dpprs')
->select('ethnic','Jantina')
->groupBy('ethnic')
->orderBy('ethnic', 'ASC')
->get();
return response()->json($dataName);
Blade is:
<select id="ethnicity" class=" ethnicity form-control select2-allow-clear" style="width:200px;" name="namaDUN" multiple >
<option value="">Select</option>
My idea is to put the result from controller function ethnicity into function fnFilters. But I dont know how can do it.
you can return response in select2 (controller function) required format
like
$final_array = [];
$ethnicity = DB::table("user")
->select("id","ethnic");
if ($request->search != '') {
$search = $request->search ;
$ethnicity=$ethnicity->where('ethnic','LIKE',"%$search%");
}
// loop the results to make response
foreach($ethnicity->get() as $key => $value):
$final_array[$key]['id'] = $value->id;
$final_array[$key]['text'] = $value->ethnic;
endforeach;
return ['results' => $final_array];
// function ends here
and select 2 tag in blade file like this
$('.ethnicity').select2({
placeholder: 'Select..',
ajax: {
url: '/select2-autocomplete-ajax_ethnicity',
minimumInputLength: 3,
data: function (params) {
var query = {
search: params.term,
page: params.page || 1
}
return query;
}
}
});
I'm successfully adopted this guide: https://laraget.com/blog/how-to-create-an-ajax-pagination-using-laravel to my needs, it works, but pagination won't work if i apply my custom filters.
Let's start with routes/web.php:
// products routes
Route::get('products', 'ProductController#index')->name('CatalogIndex');
// sorting products with custom filters
Route::post('products', 'ProductController#Filters');
Then we're going to ProductController.php:
public function index(Request $request)
{
$products = Product::orderBy('created_at', 'desc')->paginate(12);
if ($request->ajax()) {
$products_view = view('includes.products', compact('products'))->render();
return response()->json(compact('products_view'));
}
return view('catalog.index', compact('products', 'power', 'area', 'source'));
}
// filtering products
public function Filters(Request $request, Product $product)
{
if ($request->ajax()) {
// using query builder here
$prods = $product->newQuery();
// sorting by price
if ($request->has('order')) {
if ($request->input('order') == 'default') {
$prods->orderBy('created_at', 'desc');
} else {
$prods->orderBy('price', $request->input('order'));
}
}
// more filters omitted for readability
$products = $prods->paginate(12);
$products_view = view('includes.products', compact('products'))->render();
return response()->json(compact('products_view'));
}
return abort(403, 'Unauthorized action.');
}
Some javascript, that makes these filters work:
$('body').on('click', '.pagination a', function(e) {
e.preventDefault();
var url = $(this).attr('href');
getProducts(url);
window.history.pushState("", "", url);
});
function getProducts(url) {
$.ajax({
method: 'get',
url: url,
success: function(data) {
$('#products').html(data.products_view);
console.log(data);
},
error: function(jqxhr, status, exception) {
console.log('Error' + exception);
}
});
}
Now is the question, normal pagination with ajax works just fine, if i don't apply any filter, but if apply the filter (select all products where power source equal to something, etc), then when i click on a pagination link, it just leads to my index method of ProductController on 2nd page ignoring my filters, also url changes to "products?page=2", i expect the following behavior -> when you apply source filter == somevalue, then clicking on 2nd page, it would display 2nd page of all products with applied source filter, now it shows just index method with simple sorting by created_at column.
You need:
on the blade partial appends the adicional parameters on the paginator like this:
{!! $products->appends(['param1' => 'val1', 'param2'=>'val2'])->links() !!}
And on your method index() do that:
if ($request->ajax()) {
return $this->filters($request, $product);
}
Good luck.
Your http methods are mismatched. Try changing your route to a "get" instead of "post" and see if that fixes it
Ended using query strings and switched to GET method.
Im using knppaginatorbundle to create pagination. I have created a jquery code to select data with ajax.
Everything is okay when I click on the page number , the content is loaded with the correct data.
But I have a problem , The pagination template is not changed after after ajax query:
previous and next links values must changed
current page must be disabled
and other changes that need to be done ...
How can I do this ?
public function listAction($page, Request $request)
{
$em = $this->getDoctrine()->getManager();
$paginator = $this->get('knp_paginator');
$qb = $em->getRepository('AppBundle:Travel')->getListTravels();
$pagination = $paginator->paginate(
$qb, $request->query->get('page', $page), 3
);
//ajax request
if ($request->isXmlHttpRequest()) {
$view = $this->renderView('#App/Frontend/Travel/list.html.twig', array(
'pagination' => $pagination
));
$response = new JsonResponse(array('ok' => $view));
return $response;
}
return $this->render('AppBundle:Frontend/Travel:travel-list-view.html.twig', array(
'pagination' => $pagination,
));
}
I have added an attr data-target to pagination template like this:
<a data-target="{{ page }}" href="{{ path(route, query|merge({(pageParameterName): page})) }}">{{ page }}</a>
View
//.....
<div id="mydiv">
// list.html.twig contains the loop
{% include "AppBundle:Frontend/Travel:list.html.twig" %}
</div>
<br>
{{ knp_pagination_render(pagination) }}
//....
<script>
$(document).ready(function () {
$("ul#pagination a").click(function (e) {
e.preventDefault();
var dataTarget = $(this).attr("data-target"); // each <a> has attr named data-target contains num of page
var hash;
hash = 'page=' + dataTarget;
window.location.hash = hash;
if (window.location.hash != "") {
$.ajax({
type: 'get',
dataType: 'json',
url: Routing.generate('frontend_travels_list', {'page': dataTarget}),
success: function (msg) {
if (msg["ok"] === undefined) {
alert('error');
} else {
$("#mydiv").html(msg["ok"]);
}
}
});
}
});
});
</script>
Route
frontend_travels_list:
path: /travels/{page}
defaults: { _controller: AppBundle:TravelFrontend:list, page: 1 }
options:
expose: true
If someone else needs a solution there 2 ways.
You can use that bundle https://github.com/nacholibre/knppaginator-ajax
You should build new pagination string in controller and send it in JsonResponse as a param. Then replace pagination element in DOM via jQuery on success.
For SF 4.3 you can use my approach
To be able to inject the Processor in controller you have to add alias for autowiring in services.yaml
Knp\Bundle\PaginatorBundle\Helper\Processor: '#knp_paginator.helper.processor'
Based on injected PaginatorInterface you should build your $pagination object (PaginationInterface)
Use Processor to build the context array for Twig.
$paginationContext = $processor->render($pagination);
render method expects SlidingPagination object, but got $pagination which is PaginationInterface - however it seems that is ok
Get the Twig and render a final string
$twig = $this->get('twig');
$paginationString = $twig->render($pagination->getTemplate(), $paginationContext);
Example of working controller
if ($request->isXmlHttpRequest()) {
$view = $this->render('#App/Frontend/Travel/list.html.twig', array(
'pagination' => $pagination
))->getContent();
$paginationContext = $processor->render($pagination);
$twig = $this->get('twig');
$paginationHtml = $twig->render($pagination->getTemplate(), $paginationContext);
$response = new JsonResponse(['view' => $view, 'paginationHtml' => $paginationHtml]);
return $response;
}
then in jQuery
success: function (msg) {
if (msg["ok"] === undefined) {
alert('error');
} else {
$("#mydiv").html(msg["view"]);
$("#myDivContainingPagination").html(msg["paginationHtml"])
}
}
http://rimi-classified.com/ad-list/west-bengal/kolkata/electronics-and-technology
The above link has a filter in the left. I am trying to use ajax to get city from state. but as the ajax is triggered the entire query is changing.
SELECT * FROM (`ri_ad_post`)
WHERE `state_slug` = 'west-bengal'
AND `city_slug` = 'kolkata'
AND `cat_slug` = 'pages'
AND `expiry_date` > '2014-03-21'
ORDER BY `id` DESC
It is taking the controller name in the query (controller name is pages).
The actual query is:
SELECT *
FROM (`ri_ad_post`)
WHERE `state_slug` = 'west-bengal'
AND `city_slug` = 'kolkata'
AND `cat_slug` = 'electronics-and-technology'
AND `expiry_date` > '2014-03-21'
ORDER BY `id` DESC
// Controller
public function ad_list($state,$city,$category,$sub_cat=FALSE)
{
if($state===NULL || $city===NULL || $category===NULL)
{
redirect(base_url());
}
$data['ad_list'] = $this->home_model->get_adlist($state,$city,$category,$sub_cat);
$this->load->view('templates/header1', $data);
$this->load->view('templates/search', $data);
$this->load->view('ad-list', $data);
$this->load->view('templates/footer', $data);
}
public function get_cities()
{
$state_id = $this->input->post('state');
echo $this->city_model->get_cities($state_id);
}
// Model
public function get_adlist($state,$city,$category,$sub_cat=FALSE)
{
if ($sub_cat === FALSE)
{
$this->db->where('state_slug', $state);
$this->db->where('city_slug', $city);
$this->db->where('cat_slug', $category);
$this->db->where('expiry_date >', date("Y-m-d"));
$this->db->order_by('id', 'DESC');
$query = $this->db->get('ad_post');
}
$this->db->where('state_slug', $state);
$this->db->where('city_slug', $city);
$this->db->where('cat_slug', $category);
$this->db->where('sub_cat_slug', $sub_cat);
$this->db->where('expiry_date >', date("Y-m-d"));
$this->db->order_by('id', 'DESC');
$query = $this->db->get('ad_post');
return $query->result_array();
//echo $this->db->last_query();
}
//ajax
<script type="text/javascript">
$(document).ready(function () {
$('#state_id').change(function () {
var selState = $(this).val();
alert(selState);
console.log(selState);
$.ajax({
url: "pages/get_cities",
async: false,
type: "POST",
data : "state="+selState,
dataType: "html",
success: function(data) {
$('#city').html(data);
$("#location_id").html("<option value=''>--Select location--</option>");
}
})
});
});
</script>
Please help me how to solve this issue. Please check the url I have provided and try to select a state from the filter section the problem will be more clear.
In .js what is the value of selState ?
In your model, you should if() else() instead of just a if, because your query will get override.
Where is the get_cities function ? Can we see it ?
On your url, the problem is that your ajax url doesn't return a real ajax call but an entire HTML page which is "harder" to work with. Try to change it into json (for dataType's ajax()) You should only do in your php something like this :
in your controller :
public function get_cities()
{
$state = $this->input->post('state');
//Do the same for $cat
if (!$state) {
echo json_encode(array('error' => 'no state selected'));
return 0;
}
$get_cities = $this->model_something->getCitiesByStateName($state);
echo json_encode($get_cities);
}
You should definitely send with ajax the $cat info
