Submitted by Muzamil-khan - 4 weeks ago

This query searches the data from the Table and also with its relation table columns dynamically.

//add this code in model

    public function scopeSearch($query, $keyword, $columns = [], $relationMapping = [])
    {
    
    // if you pass empty column list then it automatically get all table column or fillable column    
        if (empty($columns)) {
        
    // 1) get all table column

    //            $columns = array_except(
    //                Schema::getColumnListing($this->table), $this->guarded
    //            );
    
    // 2) get fillable column
            $columns = $this->fillable;
        }

        $query->where(function ($query) use ($keyword, $columns, $relationMapping) {
            foreach ($columns as $key => $column) {
                $clause = $key == 0 ? 'where' : 'orWhere';
                $query->$clause($this->table.'.'.$column, "LIKE", "%{$keyword}%");

                if (!empty($relationMapping)) {
                    $this->filterByRelationship($query, $keyword, $relationMapping);
                }
            }
        });
        return $query;
    }
