Laravel在合并后获得更新的请求值

Question

I am attempting to modify a Laravel Request object using merge to update the key trial_end.

I am doing this using the following code...

if ($this->request->get('trial_end', '')) {
    $this->request->merge(array('trial_end' => 'test'));
}
dd($this->request->all(), $this->request->get('trial_end'));

I expect $this->request->get('trial_end') to be test, but it is not. $this->request->all() returns what I expected.

Result of die dump

array:1 [
  "trial_end" => "test"
]
"12/4/2018" 

How come it is not returning the updated value?

Answer 1

Figured it out. The solution was to change

$this->request->get('trial_end');

to

$this->request->input('trial_end');

This works because input() adds the data in all() to getInputSource()->all() before doing a data_get on that, whereas get() just performs a data_get on the input parameters (pre-modifications).

New code (with a change suggested by Alex)

if ($this->request->has('trial_end')) {
    $this->request->merge(['trial_end' => 'test']);
}
dd($this->request->all(), $this->request->input('trial_end'));

New results

array:1 [
  "trial_end" => "test"
]
"test"

Hope this helps any others that come across this issue.
