how to display data from self created array in laravel? - php

Question

I create an array for the blade view. Collect the data from table and store in an array, $post_data. For laravel generated array, foreach loop will do the job. But, it seems a different things with self created array. Please help.
I use 2 foreach because the array consist of 2 dimensional array.
The result of dd($post_data)
The result of var_dump($data)
The result of var_dump($item)

Controller
$RMM = DB::table('companies')->where('branch', 'RMM')->get();
foreach ($RMM as $RMM)
{
$post = post::find($RMM->id);//get post for each department
if (isset($post))
{
$post_data[] = array('title' => $post->article_title,
'name' => $RMM->department.'#'.$post->author,
'date' => date('Y-m-d', strtotime($post->date)),
);
}
}
Blade

Answer 1

The problem is you are tying to access a property of a NON OBJECT as the error says.
item is not an object, it's an array.
so you have to use the array access method to access its values.
#foreach($post_data as $key => $data)
#foreach ($data as $item)
<div class="col bg-light ">
<a class="nav-link pb-0 pt-0" href="#">{{ $item['title'] }}</a>
<a class="nav-link pb-0 pt-0" href="#">{{ $item['name'] }}
# {{$item['department'] }}</a>
</div>
#endforeach
#endforeach
UPDATE
Looking at the dump of the $post_data realized that you don't have to loop each element of the array again.
#foreach($post_data as $key => $data)
<div class="col bg-light ">
<a class="nav-link pb-0 pt-0" href="#">{{ $data['title'] }}</a>
<a class="nav-link pb-0 pt-0" href="#">{{ $data['name'] }}</a>
</div>
#endforeach

If you just want get the title, name and date it's simple
Controller
post_data = Array();
$RMM = DB::table('companies')->where('branch', 'RMM')->get();
foreach ($RMM as $RMM)
{
$post = post::find($RMM->id);//get post for each department
if (isset($post))
{
$post_data[] = array(
'title' => $post->article_title,
'name' => $RMM->department.'#'.$post->author,
'date' => date('Y-m-d', strtotime($post->date)),
);
}
}
// You can send a array of objects
return view('example')->with('posts', $post_data);
View
#foreach($posts as $post)
<div class="col bg-light ">
<a class="nav-link pb-0 pt-0" href="#">{{ $item['title'] }}</a>
<a class="nav-link pb-0 pt-0" href="#">{{ $item['name'] }}
# {{$item['department']}}</a>
</div>
#endforeach

I correct it. Thank you for all the comments and advice. Here is how I do it.
The $post_data[] is correct since I need to store a lot of return result from find function. Since, find already return an array of corresponding id, I do not need to put into another array, just use it as it is, as explain by #Ghost. Thus, one foreach enough to get the job done.
Controller
$RMM = DB::table('companies')->where('branch', 'RMM')->get();
foreach ($RMM as $RMM)
{
$post = post::find($RMM->id);//get post for each department
if (isset($post))
{
$post_data[] = $post;
}
return view('home')->with('posts', $post_data);
}
Blade
#foreach($posts as $post)
<div class="col bg-light ">
<a class="nav-link pb-0 pt-0" href="#">{{ $item['title'] }}</a>
<a class="nav-link pb-0 pt-0" href="#">{{ $item['name'] }}
# {{$item['department']}}</a>
</div>
#endforeach

Update answer
Another method, is to convert the array into object. The error is about non-object, directly working on it would help.
ERROR: Trying to get property 'title' of non-object.
Alternative way
$RMM = DB::table('companies')->where('branch', 'RMM')->get();
foreach ($RMM as $RMM)
{
$post = post::find($RMM->id);//get post for each department
if (isset($post))
{
$post_data[] = array('title' => $post->article_title,
'name' => $RMM->department.'#'.$post->author,
'date' => date('Y-m-d', strtotime($post->date)),
);
}
}
//change to object before send to blade
$object = json_decode(json_encode($post_data), FALSE);
return view('home')->with('posts', $object);
