Save all values in Uppercase Laravel 5+ - laravel-5

Question

What would be the best way to save all values in the database as uppercase. So before saving convert all strings to uppercase. I see options to use Events or a trait would probably be best but not quite sure how to achieve this. I do not want to create accessors & mutators for each of my fields.
Got this from : https://laracasts.com/discuss/channels/eloquent/listen-to-any-saveupdatecreate-event-for-any-model
trait Trackable {
public static function bootTrackable()
{
static::creating(function ($model) {
// blah blah
});
static::updating(function ($model) {
// bleh bleh
});
static::deleting(function ($model) {
// bluh bluh
});
}
}
Im not sure how I would be able to get the actual request values to convert them to uppercase?

Answer 1

As #Louwki said, you can use a Trait to do that, in my case I did something like this:
trait SaveToUpper
{
/**
* Default params that will be saved on lowercase
* #var array No Uppercase keys
*/
protected $no_uppercase = [
'password',
'username',
'email',
'remember_token',
'slug',
];
public function setAttribute($key, $value)
{
parent::setAttribute($key, $value);
if (is_string($value)) {
if($this->no_upper !== null){
if (!in_array($key, $this->no_uppercase)) {
if(!in_array($key, $this->no_upper)){
$this->attributes[$key] = trim(strtoupper($value));
}
}
}else{
if (!in_array($key, $this->no_uppercase)) {
$this->attributes[$key] = trim(strtoupper($value));
}
}
}
}
}
And in your model, you can specify other keys using the 'no_upper' variable. Like this:
// YouModel.php
protected $no_upper = ['your','keys','here'];

Was a lot easier than I through. Solution that is working for me using traits, posting it if anyone also run into something like this.
<?php
namespace App\Traits;
trait SaveToUpper
{
public function setAttribute($key, $value)
{
parent::setAttribute($key, $value);
if (is_string($value))
$this->attributes[$key] = trim(strtoupper($value));
}
}
}
UPDATE:
For Getting values as upper case you can add this to the trait or just add it as a function in the model:
public function __get($key)
{
if (is_string($this->getAttribute($key))) {
return strtoupper( $this->getAttribute($key) );
} else {
return $this->getAttribute($key);
}
}
