[英]php laravel array_merge key value
嗨,我正在創建一個數組,它將在我的網站中存儲部分。 這些部分中的某些部分將對某些用戶不可用,因此在放入陣列之前,我需要檢查相關用戶的許可。 但是,當我執行此if語句時,我在不需要的數組中得到一個數組,這會導致以下錯誤:
Method Illuminate\\View\\View::__toString() must not throw an exception
這是我正在使用的代碼:
$user = Auth::user();
if(($user->hasRole('Admin') || $user->hasRole('Admin') || $user->hasRole('Project Master') || $user->hasRole('Project Owner'))) {
$restrictsections = ['Create' => route('project.create'),
'Sort' => route('project.sort'),];
}
$this->sections = [
'Projects' => [
'View' => route('project.index'),
$restrictsections
]
];
現在,數組的結構如下:
array(1) {
["Projects"]=>
array(2) {
["Create"]=>
string(30) "http://projects.local/projects"
[0]=>
array(2) {
["Create"]=>
string(37) "http://projects.local/projects/create"
["Edit"]=>
string(35) "http://projects.local/projects/sort"
}
}
}
相對於:
$this->sections = [
'Project' => [
'View' => route('project.index'),
'Create' => route('project.create'),
'Sort' => route('project.sort'),
]
];
array(1) {
["Project"]=>
array(3) {
["View"]=>
string(30) "http://projects.local/project"
["Create"]=>
string(37) "http://projects.local/project/create"
["Sort"]=>
string(35) "http://projects.local/project/sort"
}
}
有什么想法可以將兩個數組合並在一起嗎? 但其結構應如下:
array(1) {
["Project"]=>
array(3) {
["View"]=>
string(30) "http://projects.local/project"
["Create"]=>
string(37) "http://projects.local/project/create"
["Sort"]=>
string(35) "http://projects.local/project/sort"
}
}
再創建一個
$this->sections = ['Projects' => $restrictsections];
$this->sections['Projects']['View'] = route('project.index');
您可以使用+
運算符組合數組。
例如:
php > print_r(['View' => '1'] + ['Create' => 'two', 'Sort' => '3']);
Array
(
[View] => 1
[Create] => two
[Sort] => 3
)
適用於您的代碼:
$user = Auth::user();
if(($user->hasRole('Admin') || $user->hasRole('Admin') || $user->hasRole('Project Master') || $user->hasRole('Project Owner'))) {
$restrictsections = ['Create' => route('project.create'),
'Sort' => route('project.sort'),];
}
$this->sections = [
'Projects' => [
'View' => route('project.index')
] + $restrictsections
];
編輯: +
從技術上講是一個並集,因此,如果第二個數組中的鍵出現在第一個數組中,則將忽略它們。
像這樣使用array_merge()
$this->sections = [
'Projects' => array_merge(
['View' => route('project.index')],
$restrictsections
)
];
或像這樣使用+
運算符
$this->sections = [
'Projects' => ['View' => route('project.index')] + $restrictsections
];
