How to Use Function inside #foreach - Laravel - php

Question

Thanks For Reading.
I'm new in Laravel, i want to try to change the output of Database with #foreach blade, there is the example :
This is Route :
Route::get('/home', 'warnajati#index');
This is Controller :
public function index()
{
$post = DB::table('posts')->get();
return view('warnajati', ['posts'=>$post]);
}
This is Views :
#foreach ($posts as $post)
<div class="title"><h3>{{$post->title}}</h3></div>
#endforeach
with Output of $post->title is "This is The Looonger Title you ever know" ,
and i want to make the title is shorter with Wordlimit() function i have made :
function wordlimit($text, $limit=10)
{
if (strlen($text)>$limit) {
# code...
$word = mb_substr($text,0,$limit-3)."...";
}else{
$word =$text;
}
};
How and Where i must place that function in laravel Project ?? please help me..

Answer 1

Your function has no return value... Laravel already has this function: http://laravel.com/docs/5.3/helpers#method-str-limit
#foreach ($posts as $post)
<div class="title"><h3>{{ str_limit($post->title, 10) }}</h3></div>
#endforeach

You can use Laravel's Accessor for doing that like this inside a Model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Post extends Model
{
public function getShortTitleAttribute($value)
{
// return shortened title here ...
}
}
and then you can use it in blade like this:
{{ $post->short_title }}
Hope this helps!

You can put your function in helpers.php file from libraries folder.
Just make sure that you have helpers.php file autoloaded in composer.json file:
"autoload": {
"files": [
"libraries/helpers.php"
],
},
If you had to add this to your composer.json you will also have to run composer dump-autoload command from terminal.
