How to change value of a request parameter in laravel - laravel

Question

I need to change value of my request parameter like this:
$request->name = "My Value!";
I use this code but does not work:
$request->offsetSet('img', $img);

Answer 1

Try to:
$requestData = $request->all();
$requestData['img'] = $img;
Another way to do it:
$request->merge(['img' => $img]);
Thanks to #JoelHinz for this.
If you want to add or overwrite nested data:
$data['some']['thing'] = 'value';
$request->merge($data);
If you do not inject Request $request object, you can use the global request() helper or \Request:: facade instead of $request

Answer 2

Use merge():
$request->merge([
'user_id' => $modified_user_id_here,
]);
Simple! No need to transfer the entire $request->all() to another variable.
Read more about Laravel's merge() here:
https://laravel.com/docs/collections#method-merge

Answer 3

If you need to customize the request
$data = $request->all();
you can pass the name of the field and the value
$data['product_ref_code'] = 1650;
and finally pass the new request
$last = Product::create($data);

Answer 4

If you need to update a property in the request, I recommend you to use the replace method from Request class used by Laravel
$request->replace(['property to update' => $newValue]);

Answer 5

Use add
$request->request->add(['img' => $img]);

Answer 6

If you use custom requests for validation, for replace data for validation, or to set default data (for checkboxes or other) use override method prepareForValidation().
namespace App\Http\Requests\Admin\Category;
class CategoryRequest extends AbstractRequest
{
protected function prepareForValidation()
{
if ( ! $this->get('url')) {
$this->merge([
'url' => $this->get('name'),
]);
}
$this->merge([
'url' => \Str::slug($this->get('url')),
'active' => (int)$this->get('active'),
]);
}
}
I hope this information will be useful to somebody.

It work for me
$request = new Request();
$request->headers->set('content-type', 'application/json');
$request->initialize(['yourParam' => 2]);
check output
$queryParams = $request->query();
dd($queryParams['yourParam']); // 2

Answer 8

Great answers here but I needed to replace a value in a JSON request. After a little digging into the code, I came up with the following code. Let me know if I'm doing something dumb.
$json = $request->json()->all();
$json['field'] = 'new value';
$request->json()->replace($json);

Answer 9

Try that :
$request["name"] = "My New Value";
$request["img"] = $img;
It's worked in Laravel 8.

Answer 10

Also, make sure to update the model class.
Item
{
fillable=[
'img',
... // other attributes
];
}

Answer 11

in case of updating an item of object you can write the lines bellow
$Obj = $request->data;
$Obj['item'] = value;
