请求 Laravel controller 中的值而不是键/id

Question

I'm fetching data from database to the invoice view page using json_encode($items); function (particularly 'price' field by it's id) from controller, it works well. But when I insert that particular field to database only the id/key is stored rather than the actual value. Any guess how to request for the value rather than key/id in controller.

Here is the controller function:

public function getPurchaseItems($id) 
   {
       $items = DB::table("purchase")->where("pur_id",$id)->pluck("price","pur_id");
       return json_encode($items);
    
   }

Here is html code:

<div class="form-group col-md-1">
      <label for="in">Price</label>
      <select name="price" readonly class="form-control prc" id="price">        
      </select>
    </div> 

Here is the script:

            jQuery('select[name="state"]').on('change',function(){
              
               var stateID = jQuery(this).val();
               if(stateID)
               {
                  jQuery.ajax({
                     url : 'invoice/getPurchaseItems/' +stateID,
                     type : "GET",
                     dataType : "json",
                     success:function(data)
                     {
                      
                        console.log(data);
                        jQuery('select[name="price"]').empty();
                        jQuery.each(data, function(key,value){
                           $('select[name="price"]').append('<option value="'+ key +'">'+ value +'</option>');
                        });
                  
                     }
                  });
               }
               else
               {
               
                
                $('select[name="price"]').empty();
                
                  
               }
            });

Here is the requested data and storing to database:

public function insertInv(Request $request){
       $price = $request->input('price');

        $invoiceId= DB::table('invoice')->insertGetId($invo);     
        $invo_det=array('invoice_no'=>$invoiceId,'price'=>$price);

         DB::table('invoice_details')->insert($invo_det);

Modify Your insertInv function

Remove input() from $price = $request->input('price'); OR dd($request->all()); and check all the values in controller are in correct format And Post the Result here
