Does laravel 5.5 changes to has also reflect blade - laravel

Question

I am currently upgrading Laravel 5.4 to 5.5 and I saw this:
The has Method
The $request->has method will now return true even if the input value is an empty string or null. A new $request->filled method has been added that provides the previous behavior of the has method.
Does this also apply to blade files?
Eg
<div class="form-group{{ $errors->has('email') ? ' has-error' : '' }}">
#if(session()->has('success'))
<script type="text/javascript">x</script>
#endif
And also does it affect files too? Eg
if ($request->hasFile('images') == false) {
//No image..
}

Answer 1

no change on any of these from version 5.4 to 5.5
session()->has('success')
$errors->has('email')
$request->hasFile('images')
changed from version 5.4 to 5.5
$request->has('something');
Below source codes are from the official github tags
Here is the Illuminate\Http's (for $request)
http has() method has been changed
has() from 5.4
/**
* Determine if the request contains a non-empty value for an input item.
*
* #param string|array $key
* #return bool
*/
public function has($key)
{
$keys = is_array($key) ? $key : func_get_args();
foreach ($keys as $value) {
if ($this->isEmptyString($value)) {
return false;
}
}
return true;
}
has() from 5.5
/**
* Determine if the request contains a given input item key.
*
* #param string|array $key
* #return bool
*/
public function has($key)
{
$keys = is_array($key) ? $key : func_get_args();
$input = $this->all();
foreach ($keys as $value) {
if (! Arr::has($input, $value)) {
return false;
}
}
return true;
}
hasFile() is same
hasFile() from 5.4
/**
* Determine if the uploaded data contains a file.
*
* #param string $key
* #return bool
*/
public function hasFile($key)
{
if (! is_array($files = $this->file($key))) {
$files = [$files];
}
foreach ($files as $file) {
if ($this->isValidFile($file)) {
return true;
}
}
return false;
}
hasFile() from 5.5
/**
* Determine if the uploaded data contains a file.
*
* #param string $key
* #return bool
*/
public function hasFile($key)
{
if (! is_array($files = $this->file($key))) {
$files = [$files];
}
foreach ($files as $file) {
if ($this->isValidFile($file)) {
return true;
}
}
return false;
}
Here is the Illumnate\Session's (for session())
session has() method is same
from 5.4
/**
* Checks if a key is present and not null.
*
* #param string|array $key
* #return bool
*/
public function has($key)
{
return ! collect(is_array($key) ? $key : func_get_args())->contains(function ($key) {
return is_null($this->get($key));
});
}
session from 5.5
/**
* Checks if a key is present and not null.
*
* #param string|array $key
* #return bool
*/
public function has($key)
{
return ! collect(is_array($key) ? $key : func_get_args())->contains(function ($key) {
return is_null($this->get($key));
});
}
Here is Illuminate\Support's MessageBag.php (for $errors)
has() from 5.4
/**
* Determine if messages exist for all of the given keys.
*
* #param array|string $key
* #return bool
*/
public function has($key)
{
if (is_null($key)) {
return $this->any();
}
$keys = is_array($key) ? $key : func_get_args();
foreach ($keys as $key) {
if ($this->first($key) === '') {
return false;
}
}
return true;
}
has() from 5.5
/**
* Determine if messages exist for all of the given keys.
*
* #param array|string $key
* #return bool
*/
public function has($key)
{
if (is_null($key)) {
return $this->any();
}
$keys = is_array($key) ? $key : func_get_args();
foreach ($keys as $key) {
if ($this->first($key) === '') {
return false;
}
}
return true;
