I'm trying to pass trough form dropdown selection but I can't pass array(the rest of the form is using objects. This is my code
Controller
$var->user = $request->users->id;
view
{!! Form::select('users', $users,null, ['placeholder' => 'Pick a user']) !!}
One solution is converting array to object using eloquent, how can that be done
If you want to get selected user's ID, I guess you need to do this:
$request->users
You're getting "Trying to get property of non-object" error, because $request->users is not an object.
If you want to get the user list you can follow this:
In Controller:
$user_id = UserModel::lists('username','id')->all();
"usename" and "id" is user-table fields.you can replace any other fields which you will show in user list.
In view:
{!! Form::select('user_id', $user_id,Input::old('user_id'),['placeholder'=>'select user']) !!}

I've got a problem in Laravel. I have passed my whole table to my view like this from my controller:
$usersTable = DB::table('users')->get();
return view('users')->with('users', $usersTable);
In a foreach loop I can perfectly get each of the values like this in my view:
#foreach($users as $user => $value)
<div class="projectBox">
<br><span class="projectBoxName">{{ $value->name }}</span>
#php
echo Form::image('/images/edit.png', "",['class' => "editUserBtn", 'userId' => $value->id]);
#endphp
<br><span class="projectBoxSmallText projectBoxEmail">{{ $value->email }}</span>
<br><span class="projectBoxSmallText projectBoxId">ID: {{ $value->id }}</span>
<br><span class="projectBoxSmallText projectBoxProjects">Currently no projects</span>
</div>
#endforeach
But I also need to access these values outside my foreach loop, how can I do that?
echo Form::text('email', "$users->$value->email", array('placeholder' => "Email"));
Ain't working...
This gives my the whole object in this form
[{"id":"1","name":"Administrator","email":"admin#mail.com","password":"$2y$10$Re3Ahf.SwU5vj4UvtU5Dy.jxaZMsUNC2WhuJMwsNy9gu6TST4PuRG","remember_token":null}]
How to get only the email? I also tried using indexes, but those weren't working.
Thanks!
Edit:
Full situation:
I have a list of users with their extra information (mail, tel,...). In those user-boxes there is a button which says 'edit user' when I click that a modal opens giving the current mail and tel. So I can't say in my controller WHO's mailaddress to return because I only know that at the moment the user clicks a client-side button.

(Edit button is that small circle with three dots).
To access a collection without using loop, you should use collection methods:
$users = User::get();
$users->where('name', 'John Smith')->first()->email
This will not create any additional queries since you've already eager loaded data.
If you want to load just one user, use first() instead of get():
$users = User::first();
If you'll use get() and then [0] or first() like some guys recommend here, you'll load all users data into the memory for each request which will overload your server.
Also, using indexes to access data (like $users[4]['email']) is a bad practice. Avoid it if possible.
You need to add as first element by adding [0]
echo Form::text('email', $users[0]->email, array('placeholder' => "Email"));
I suggest use ->first() instead of ->get() to get single object. And remove loop and use anywhere you want.
You are using a collection of users to get the first user's email, you do
$users->first()->email;
Looks like it's coming in as JSON. Try json_decode($data) and $data->email to get that attribute.
I want to get the selected value from a drop down list in a controller method.
The drop down list :
{{ Form::select('Organization', $organization_list ,Input::old('Organization'), array('class' => 'form-control')) }}
$organization_list is an array of organizations..
I have tried to catch the selected item of this drop down list in a controller as follows:
Input::get('Organization');
But it gives me the array index instead of the real organization name..But the real organization name is shown in drop down list.. does anyone have a solution?
Pass an associative array To Form::select as the second argument
$organization_list = array_combine($organization_list, $organization_list); //Copies the array values to keys
{{ Form::select('Organization', $organization_list ,Input::old('Organization'), array('class' => 'form-control')) }}

I'm trying to figure out how I can structure my Laravel select menu so that it shows up as this for a final render. Has anyone done such a thing.
The location is a property of the arena object.
<option value="arena_id">Arena Name - Location</option>
{{ Form::select('arena_id', [ null => 'Please Select'] + $arenas, null, ['id' => 'arena_id']) }}
I asssume $arenas comes from something like Arena::where('foo', bar)->get(), but with get() you will get an instance of Illuminate\Database\Eloquent\Collection instead of an actual array which is what you want in Form::select.
So what you need to do is to use lists($field, $key), it will fetch you rows and return it as an array.
$arenas = Arena::where('foo', bar)->lists('name', 'id');
There is a code example here with some comments from users if you want to learn more.
You can use pluck function for getting the results as array
refer https://laravel.com/docs/5.1/collections#method-pluck
$select = $this->all()->pluck('title', 'id');
Then you can use below sample code for creating select box with selected option in blade template
{{ Form::select('name',$select,'selected option id',['class' => 'form-control']) }}
I got value from database and then i need to set those value to textbox. I have created a controller file with the method name of edit look like below
userdata.blade.php:
public function edit($id)
{
echo "You have clicked edit link".$name;
$editdata = DB::table('newuser')->where('Id','=',$id)->get();
return View::make('editdata',array('list' => $editdata));
}
I have passed array of value as parameter to the view file.now i need to diaplay the value of name to textbox.how to do that in html page using laravel. My html page look like below
editdata.blade.php:
<html>
<head></head>
<body>
<div>
{{Form::open(array('url' => 'login', 'method' => 'post'))}}
{{Form::label('name','Name',array('id'=>'label-name'))}}
{{Form::text('name',{{$list->Name}}}}
{{ Form::close() }}
</div>
</body>
</html>
can anyone tell me that what mistake i did.Thanks in advance
Just remove the curly brackets, you are already "inside" PHP code and don't need them:
{{ Form::text('name',$list->Name) }}
Also you get a collection from your controller you probably want to do:
$editdata = DB::table('newuser')->where('Id','=',$id)->first();
Or even:
$editdata = DB::table('newuser')->find($id);
get() returns a collection (multiple rows) and not the model itself. You can use User::find($id) which gives you direct access to the model with the specified Id.
When not using eloquent just replace get() with first()
I'm using Laravel framework and i have two dropdown lists of which both are reading data from the database tables,
the first one it read all the records from the table and populate it on the select list
here is my code:
<div class="form-group">
{{Form::select('advertiserName', Advertiser::all()->lists('advertiserName', 'advertiserId'))}}
</div>
it display the advertiser name and also passes the id on the advertiser.
The second dropdown i want it to display all the Brands related to the above selected advertiser.
here is my code:
<div class="form-group">
{{Form::select('brandName', Brand::where('advertiserId', '=', '3')->lists('brandName', 'id'))}}
</div>
The advertiserId is the foreign key of the advertiser and 3 must be replaced by the the advertiserId you selected on the first dropdown list, basically i want to pass variable from the first select list to the second one
Thank you
Basically you need to use AJAX to get data for Second Dropdown based on option selected from first dropdown.
Create Second Dropdown inside specific div and After ajax Call replace contect of div from ajax response.
As stated, the best way to achieve this is via an AJAX request. Here is an example of how you can achieve this functionality.
Firstly create a view partial that renders the select box for brands. Something like this (this code is based on Bootstrap 3):
{{ Form::label('brandName', 'Brand', ['class' => 'control-label col-sm-2']) }}
<div class="col-sm-10">
{{ Form::select('brandName', $brands, null, ['class' => 'form-control']) }}
</div>
Now, in your routes.php file add the following route:
Route::get('brand-list/{id}', ['as' => 'brands', 'uses' => 'BrandsController#brandList']);
In your BrandsController.php file (or whatever controller your using to handle this) add a method called brandList();
public function brandList($id)
{
// Return an array of brands for the selected advertiser name ID if available
$brands = $this->brand->where('advertiserId', $id)->lists('brandName', 'id'); // I'm using dependency injection here so you'll need to assign your Brand model to the $this->brand property of this classes constructor method
if ( ! isset($brands))
{
$brands = ['No brands available' => null]; // return a generic array containing 1 item with a value of null so you can handle it in your view. You could also return something else here such a boolean of false and then handle that in your AJAX request to return an error or info message
}
return View::make('brands.partials.select', compact('brands'));
}
Now for the AJAX:
$('#advertiserName').change(function(e) {
var advertiserId = $(this).val();
var url = '/brand-list/' + advertiserId;
$.get(url, function(data) {
$('.brands').html(data); // The returned view with the brand select input
});
});
Then in your initial form view you'll want to create an empty div with a class of .brands that we'll use to populate with the HTML returned via our AJAX request. Something like this if you're using Bootstrap 3 for example:
<div class="form-group brands"></div>
This should work as you need but I haven't tested this code, so if you have any issues let me know. Obviously this is generic code based on the info available and there are many ways to skin a cat.
