Present summary content in Laravel 5.1

Question

I have a controller that performs a paged query:

$noticias = Noticias::orderBy('created_at', 'desc')->paginate(4);

However, one of the returned columns is the content. The column in question has a lot of text, as well do in Laravel so that it returns only a summary containing the first 380 characters or so the first 200 words?

Answer 1

In the Laravel there is a resource that allows us to return a value, in a model property, as if it were in the table.

For example, if you have the field conteudo in your table, you will be able to make the magic property conteudo_resumido is returned from that original content.

We can do this by adding a method in Model, which starts with get, followed by the name with Studlycase, and then with the word attribute. That is to say:

MeuModel::getConteudoResumidoAttribute()

Example:

class Post extends \Eloquent
{

    protected $appends = ['conteudo_resumido'];
    public function getConteudoResumidoAttribute()
    {
        return str_limit($this->getAttribute('conteudo'), 200, '...');
    }
}

From this, we can do the following in the call of our model Post:

@foreach($posts as $post)
   <li>{{ $post->conteudo_resumido }}
@endforeach

I used the property appends to determine that the magic method will be loaded along with the result brought from a common query, as in case you need it in the json, it will already be automatically returned.

Updating

If you are facing problems with broken HTML tags because of the "truncate" generated by the function str_limit, just change the method described above by placing the function strip_tags before the use of str_limit.

str_limit(strip_tags($this->getAttribute('conteudo')), 200);

Thus, only text characters, not tag characters, will be counted, and you will not have problems with broken HTML tags.

Answer 2

I managed to do so:

{{ preg_replace('/(<.*?>)|(&.*?;)/', '', \Illuminate\Support\Str::words($noticia->conteudo, 70, "...")) }}

With this I can remove the html tags and special formatting, as well as limit to a total of 70 words before inserting the three points, elements that represent the continuity of the content.
