Laravel how to pass data from controller to modal dialogue using ajax - php

Question

I have items and for every item there are related items, so when I open the homepage it shows all item, when I want to click on any item, ajax will pass this item id to controller to get the related items for this item, the problem is I want to show the related item in a modal dialogue, the modal dialogue now show all related items to all items not to the current item.
I think the problem is because the include of modal in the homepage which has the foreach!, hope you can help me in solving this issue
route
Route::get('/',['as'=>'showItems','uses'=>'HomeController#getItem']);
Route::get('Get_relateditem',['as'=>'Get_relateditem','uses'=>'HomeController#getItem']);
ajax
$(function(){
$('.Item_root').on("click", function () {
var item_id = $(this).data('id');
$.ajax({
type:'get',
url: '/',
data: {
'_token': $('input[name=_token]').val(),
'item_id':item_id,
},
success:function(data){}
});
});
});
controller
public function getItem(Request $request)
{
$currentitemid =$request->item_id;
$ritems = Relateditem::orderBy('id', 'asc')->where('ritemf_id','LIKE','%'.$currentitemid.'%')->with('items')->get()->groupBy('ritemf_id');
$items = Item::orderBy('category_id', 'asc')->with('category')->get()->groupBy('category_id');
$categories = Category::orderBy('category_id', 'asc')->get();
return view('home')->with('items',$items)->with('categories',$categories)->with('ritems',$ritems);
}
}
modal
#foreach($ritems as $item_id => $realtedItems)
#foreach($realtedItems as $ritem)
<div class="SuggestedItem_container">
<label color="red" class="Checker_root Checker_red Checker_left">
<input type="checkbox" class="Checker_input" value="on">
<div class="SuggestedItem_nameContainer">
<div>
<span class="SuggestedItem_name">{{$ritem->riteml_id}}</span>
<span class="SuggestedItem_price styles_small styles_base styles_spacing-base">+$3.95</span></div></div>
<div class="SuggestedItem_description styles_small styles_base styles_spacing-base">
<span class="SuggestedItem_category styles_bold">Appetizers</span>
<span> · Edamame soybean pods harvested right before the beans begin to harden are lightly boiled and seasoned with sea salt.</span>
</div>
</label>
</div>
#endforeach

Answer 1

Modify routes:
Route::get('/','HomeController#getItem');
Route::get('/get_related_items/{id}','HomeController#getRelatedItems');
modify getItem to get only the items and categories:
public function getItem(Request $request)
{
$items = Item::orderBy('category_id', 'asc')
->with('category')->get()
->groupBy('category_id');
$categories = Category::orderBy('category_id', 'asc')->get();
return view('home',['items' => $items,'categories' => $categories]);
}
get related items for a single item id:
public function getRelatedItems(Request $request, $id)
{
$ritems = Relateditem::orderBy('id', 'asc')
->where('ritemf_id',$id)
->with('items')
->get()
->groupBy('ritemf_id');
return response()->json($ritems);
}
now for the js part:
$(function(){
$('.Item_root').on("click", function () {
var item_id = $(this).data('id');
$.ajax({
type:'get',
url: '/get_related_items/' + item_id,
data: {
'_token': $('input[name=_token]').val()
},
success:function(data){
if(data && data.length){
var con_el = $('.SuggestedItem_container');
for(var i = 0; i < data.length;i++){
var related_item_el = "<div class='related_item'><p>" + data[i].id + "</p></div>"
con_el.append(related_item_el);
}
}else{
console.log('no related items found');
}
}
});
});
});
this will insert all the related items inside the SuggestedItem_container
i didn't write the view template cuz that part is easy, and note that i only included the related item id as example cuz i don't know what fields the item has.
i hope this helps you
