" Laravel Session Array " Printing a created session array in Laravel
提问by Ronser
I have created a session array in laravelusing the code:
我使用以下代码在 laravel 中创建了一个会话数组：
Session::put("backUrl", array($workout_id =>URL::previous())) ;
//or
Session::push("backUrl.$workout_id", URL::previous()) ;
Both works and it has been created successfully and I could see it in the debugger
两者都有效并且已成功创建，我可以在调试器中看到它
'backUrl' => array(1) [
'78' => string (36) "http://192.241.4.104/admin/view?cs=1"
]
now I am unable to print it, The code i have used is
现在我无法打印它，我使用的代码是
echo Session::get("backUrl"[$workout_id]);
it shows a syntax error, unexpected '['error
它显示一个syntax error, unexpected '['错误
And I have also used
我也用过
echo Session::get("backUrl[$workout_id]");
nothing works
没有任何效果

Because you keyed your entire array under the session variable "backurl".
因为您在会话变量“backurl”下键入了整个数组。
if you var_dump:
如果你 var_dump：
var_dump(Session::get("backUrl")):
I am pretty sure you get:
我很确定你会得到：
array(
[2] => "http://previous-url"
)
So wether you go like this:
所以你可以这样：
$lastUrl = Session::get("backUrl");
echo array_keys($lastUrl)[0]; //workout-ID
echo array_values($lastUrl)[0]; //Value
Or you save your two variables seperately:
或者你分别保存你的两个变量：
Session::put("backUrl", URL::previous());
Session::put("lastWorkoutId", $workout_id);
And then read them individually:
然后单独阅读它们：
Session::get("backUrl");
Session::get("lastWorkoutId");

After several trials I have got what I wanted a session array for back button URLand thanks to @Steini for his valuable suggestions. I am posting this as it could be useful to someone...
经过几次试验，我得到了我想要的后退按钮 URL 的会话数组，感谢@Steini 的宝贵建议。我发布这个是因为它可能对某人有用......
At first I have changed using
起初我改变了使用
Session::put("backUrl", array($workout_id =>URL::previous())) ;
to
到
Session::put("backUrl.$workout_id", URL::previous()) ;
Saw the Session::push tag in Laravel Docsand tried luckly it worked. Because the first one deletes the existing session array and creates a new one.
在 Laravel Docs 中看到了Session::push 标签并幸运地尝试了它的工作。因为第一个删除了现有的会话数组并创建了一个新的。
And printing the Laravel session array is as simple as printing a session with added suffix
打印 Laravel 会话数组就像打印添加后缀的会话一样简单
Session::get("sessionArrayName")['id']
(i.e)
Session::get("backUrl")[$workout_id];
Thus got my session array printed and used it for my back button....
因此打印了我的会话数组并将其用于我的后退按钮......
