How to display a cookie value in laravel 5.4 blade by interpolation or using conditions ?
Somewhat like this:
#if (Cookie::get('user_first_name') !== null)
<a href="javascript:;" id="user_name">
<i class="fa fa-sign-in" aria-hidden="true"></i>{{ Cookie::get('user_first_name') }}
</a>
#else
The way you suggested is correct:
{{ Cookie::get('user_first_name') }}
Given your comment, you probably did not set the cookie correctly. You may try:
Cookie::queue('user_first_name', 'John', 15);
return view('the-view');

I want to make ADD button only visible to admin-type user. My code looks like this:
#foreach($users as $user)
#if(Auth::user()->type=='admin')
<a href="{{ route('User.create', ['id'=>$user->id ]) }}" class="btn btn-default</i> ADD</a>
#endif
#endforeach
But, it returns lot of ADD button according to number of all users because of foreach loop. If I remove foreach loop, it will show error:
Undefined variable: user
How can I solve this problem?
It's because of you are removing the foreach , but using the variable $user again inside the routes .
Please remove the $user->id and instead, use Auth::user()->id .
#if(Auth::user()->type=='admin')
<a href="{{ route('User.create', ['id'=>Auth::user()->id ]) }}" class="btn btn-default</i> ADD</a>
#endif
You do not need to use foreach loop to check authenticated user having type admin
You need to remove passing id into the user.create route
#if(Auth::user()->type == 'admin')
<a href="{{ route('User.create') }}" class="btn btn-default</i> ADD</a>
#endif
I have this on my blade file:
{{ Form::open(['route' => 'my_route_name']) }}
<button type="submit" class="btn btn-sm btn-success">
<i class="fa fa-file-excel-o" aria-hidden="true"></i> Download
</button>
{{ Form::hidden('my_ids', $my_ids) }}
{{ Form::close() }}
Checking on the chrome's developer mode, the value of my hidden textbox named my_ids is:
[1,2,3,4,5,6]
Upon clicking the Download button, it goes on my controller:
$results= Model::whereIn('id', $request->my_ids)->get();
This is where I am getting an error.
DD-ing dd($request->my_ids) on my controller gives me "[1,2,3,4,5,6]".
However, if I just put the values directly on the eloquent query like below, it would work.
$results= Model::whereIn('id', [1,2,3,4,5,6])->get();
Am I missing something here?
Your dd shows that $request->my_ids is a string, therefore you must parse it before you use it as array.
Try
$results= Model::whereIn('id', json_decode($request->my_ids))->get();
I want to delete a record but I haven't been successful, apparently my code is wrong. Solutions i came across say i have to use a post in my form method and add the method_field helper. This would mean my view having a form in it, i want to avoid this if possible. Is it then possible to do my delete another way. Below is my code
snippet of my view
<div class="backbtn">
<a class="btn btn-savvy-delete" href="/tasks/{{$task->id}}" data-toggle="tooltip" title="Delete"><i class="fa fa-trash-o" aria-hidden="true"> Delete</i></a>
</div>
<div class="panel-body">
<p><strong>Owner:</strong> {{ ucfirst($task->employee->firstname) }} {{" "}} {{ ucfirst($task->employee->lastname) }}</p>
<p><strong>Task:</strong> {{ $task->title }}</p>
<p><strong>Description:</strong> {{ $task->description }}</p>
</div>
TaskController
public function destroy($id)
{
Task::destroy($id);
Session::flash('status', "Task was successfully deleted.");
return redirect('/tasks');
}
web.php
Route::delete('/tasks/{id}', 'TaskController#delete');
Im not sure what error you are getting, but i can point out a few things. For one use Route::get instead of ::delete, you are calling it via a link not a form method.
Secondly to delete follow what the laravel doc says here eg.
$task = App\Task::find(1);
$task->delete();
I have the following blade code:
<a href="{{ route('settings') }}">
<span class="title">Settings</span>
</a>
I have the following defined at the top of my routes.php file:
Route::post('settings/update', 'SettingsController#update');
Route::resource('settings', 'SettingsController');
When I try to go to any page with route('settings') I get a Route [settings] not defined error.
If I do php artisan routes I can see that the settings routes are all there as expected.
With route('settings') you refer to a route named settings but you don't have such a route. RESTful routes will automatically receive a route name though.
For the index method it is resource.index for the show method resource.show and so on.
Change your code to this:
<a href="{{ route('settings.index') }}">
<span class="title">Settings</span>
</a>
Change {{ route('settings') }} to {{ URL::to('settings') }}
I'm trying to get my flash message to display.
This is in my routing file
Route::post('users/groups/save', function(){
return Redirect::to('users/groups')->withInput()->with('success', 'Group Created Successfully.');
});
This is in my view
{{ $success = Session::get('success') }}
#if($success)
<div class="alert-box success">
<h2>{{ $success }}</h2>
</div>
#endif
But nothing is working.
When I try this, I get an error Variable $success is undefined. But it actually shows the flash message too.
{{ Session::get('success') }}
#if($success)
<div class="alert-box success">
<h2>{{ $success }}</h2>
</div>
#endif
This works for me
#if(Session::has('success'))
<div class="alert-box success">
<h2>{{ Session::get('success') }}</h2>
</div>
#endif
if you are using bootstrap-3 try the script below for Alert Style
#if(Session::has('success'))
<div class="alert alert-success">
<h2>{{ Session::get('success') }}</h2>
</div>
#endif
when you set variable or message using ->with() it doesn't set the variable/message in the session flash, rather it creates an variable which is available in your view, so in your case just use $success instead of Session::get('success')
And in case you want to set the message in the session flash the use this Session::flash('key', 'value'); but remember with session flash the data is available only for next request.
Otherwise you can use Session::put('key', 'value'); to store in session

two methods:
Method 1 - if you're using
return Redirect::to('users/groups')->withInput()->with('success', 'Group Created Successfully.');
under your controller create(), add in
$success = Session::get('success');
return View::make('viewfile')->with('success', $success);
then on view page,
#if (isset($success))
{{$success }}
#endif
What's happening in method 1 is that you're creating a variable $success that's passed into your create(), but it has no way of display $success. isset will always fail unless you set a variable to get the message and return it.
Method 2 - use return Redirect withFlashMessage
return Redirect::route('users/groups')->withFlashMessage('Group Created Successfully.');
then on your view page,
#if (Session::has('flash_message'))
{{ Session::get('flash_message') }}
#endif
Method 2 is much cleaner and does not require additional code under create().
{{ Session::get('success') }}
This just echos the session variable 'success'. So when you use
{{ Session::get('success') }}
#if($success)
<div class="alert-box success">
<h2>{{ $success }}</h2>
</div>
#endif
you are seeing it's output along with the error of the next statement. Because with() function only sets the value in Session and will not set as a variable. Hence #if($success) will result in undefined variable error.
As #Andreyco said,
#if(Session::has('success'))
<div class="alert-box success">
<h2>{{ Session::get('success') }}</h2>
</div>
#endif
This should work.
The reason you are not seeing it might be because the action you are performing is not success. And this does not require you to either reinstall xampp or modify php.ini.
Laravel 4.2
Personally i use
Session::flash('key', 'value');
return Redirect::to('some/url');
then in the view id first check if there is a session of that key in the view
#if(Session::has('key'))
{{Session::get('key')}} //this prints out the message or your 'value' in the session::flash method
#endif
it works for me most of the time and i usually have that blade template integrated into my view just so i can push success messages to the view from my codes.
please do note that it is stated in the documentation that "Sometimes you may wish to store items in the session only for the next request. You may do so using the Session::flash method" so yes it expires after the next page.
hope this helps
i just realized in using the Redirect::to(), when you use the withInput() method, chaining a with() function to pass variables will not work. the only way is either you flash your inputs separately using Input::flash(), and use the with() to pass your variables or you pass your variable via session using Session::flash('key','val') and retrieve in the view via session::get('key').
This link describes how to do this http://vegibit.com/flash-messages-in-laravel/
Just tried with laravel 5 - works to me.
Inside of the routes.php file try to create your routes within the
Route::group(['middleware' => ['web']], function () {
//routes here
}
then use
#if(Session::has('success'))
<div class="alert-box success">
<h2>{{ Session::get('success') }}</h2>
</div>
#endif
I fixed mine by changing the session driver in config/session.php from array to file !
