Undefined variable: name Laravel

I am trying to make an edit form but when I fire the editData Function it Gives me the error
which is ‘Undefined variable: name‘.I tried so Hard to Find the solution but nothing works
Maybe I’m missing something which I don’t know. I Need Help to Move Forward.

Here is my code:-

ProductControlller.php

<?php

namespace AppHttpControllers;

use AppProduct;
use IlluminateHttpRequest;
use IlluminateSupportFacadesDB;
class ProductController extends Controller
{
    
    public function InsertForm()
    {
    return view('prodInsert');
    }


    
    public function Prodcreate(Request $request)
    {
        $pName=$request->input('pname');
        $pPrice=$request->input('pprice');
        $pDesc=$request->input('pdesc');
        $pQuantity=$request->input('pquantity');

            $data=array('pname' =>$pName,'pprice' =>$pPrice,'pdesc' =>$pDesc,'pquantity' =>$pQuantity);
        DB::table('products')->insert($data);
        echo "Record Inserted Succefully<br>";
        echo "<a href='/Display'>Display Data</a><br>";
        echo "<a href='/prodInsert'>Add Product</a>";


    }

 
    public function selectData(Request $request)
    {
        $tabledata=DB::select('select * from products');
        return view('Display',['tabledata'=>$tabledata]);
       }

    public function deleteData(Request $request,$id){
        DB::table('products')->delete($id);
        return redirect('Display');

        }
      public function show($id)
        {
            $tabledata=DB::select('select * from products where id = ?',[$id]);
            return view('editform',['tabledata'=>$tabledata]);
        }

 
    public function editData(Request $request,$id)
    {
         $pName=$request->input('name');
        $pPrice=$request->input('price');
        $pDesc=$request->input('desc');
        $pQuantity=$request->input('quantity');

         DB::update('update products set pName=?','pPrice=?','pDesc=?','pQuantity=?',[$name,$price,$desc,$quantity,$id]);


   
    }
   

}

And this is my EditForm.blade.php

<!DOCTYPE html>
<html>
<head>
    <title>PROD INSERT</title>
</head>
<body>

    <form action="/edit/<?php echo $tabledata[0]->id; ?>">

    @csrf
    <h4 align="center"><a href="Display"> Click here</a> Edit</h4>

    <table align="center">
        <tr>
            <td>Product name</td>
            <td><input type="text" name="name" value="<?php echo$tableData[0]->product_name; ?>"></td>
        </tr>
        <tr>
            <td>Product Price</td>
            <td><input type="text" name="price"></td>
        </tr>
        <tr>
            <td>Product Description</td>
            <td><input type="text" name="desc"></td>
        </tr>
        <tr>
            <td>Product Quantity</td>
            <td><input type="text" name="quantity"></td>
            <br>
        </tr>

            <td><input type="submit" name="submit"></td>

        
    </table>
</form>


</body>
</html>

I can provide more code if needed.
Thanks for Your Support 🙂
