how to update json key value in laravel - laravel

Question

we try to update the json data key value.we stored record in database product_name column like
{"ar":"arabic product","en":""}
we try to achieve this both below two method
DB::table('products')
->where('id', 1)
->update(['productname->en' => 'english product']);
$post = product::find($product_id);
$post->product_name = [$language => $edittitle];
$post->save();
we want to update the json en key value.

Answer 1

A quick and easy solution to update all the entries in one go:
Product::each(function ($product) {
$productName = json_decode($product->product_name, true);
$productName['en'] = 'english product';
$product->product_name = json_encode($productName);
$product->save();
});
If you want to update a single product, this should work:
$product = Product::find($product_id);
$productName = json_decode($product->product_name, true);
$productName['en'] = 'english product';
$product->product_name = json_encode($productName);
$product->save();

Answer 2

First thing is to create that field with the right type in the migration file, the keyword we need there is json:
...
$table->json('productname');
...
Then we need to cast that attribute to the right type when retrieving it as Eloquent model by using $casts attribute on the model itself:
...
/**
* The attributes that should be cast to native types.
*
* #var array
*/
protected $casts = [
'productname' => 'array'
];
...
Then we can access and save data for this attribute like so:
$myModel = product::find(1);
$myModel->productname['en'] = 'something';
// or
$myModel->productname = ['en' => 'something']; // This will override the whole attribute
