I am trying to call a variable in my Models/Images.php which is for a very good reason but cannot.

My variable $langtitle = 'title'.config('app.LANG_COLUMN_CODE'); which I want to use instead of 'title' within protected $searchable

Here is my whole code:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use App\Http\Controllers\Traits\Search;

class Images extends Model
{
    use Search;
    protected $guarded = array();
    public $timestamps = false;
    protected $fillable = [
        'title', 'description', 'categories_id', 'metakeywords', 'hash', 'subgroup','subcategories_id'];

        protected $searchable = [
            'title',
            'metakeywords',
            'subgroup'
        ];
    public function user() {
        return $this->belongsTo('App\Models\User')->first();
    }
     public function category() {
         return $this->belongsTo('App\Models\Categories', 'categories_id');
     }
      public function subcategories() {
         return $this->belongsTo('App\Models\Subcategories', 'subcategories_id');
     }
      public function tags() {
         return $this->hasMany('App\Models\Images', 'metakeywords');
     }
}

I get errors like Constant expression contains invalid operations

CodePudding user response：

As $searchable is getting called somewhere, better to use it directly where this $searchable is gettinh called.

See for $this->searchable and replace with:

$langtitle.",".'subgroup, metakeywords';

Hint: As I can understand, this might be in Search Traits!
