Update multiple rows of database in Laravel - php

Question

I want a code for update multiple rows of database, somthing like this:
UPDATE values SET data='{"options":["male","female"],"default":"male"}' where project_id=1 and id=1;
UPDATE values SET data='{"options":["male","female"],"default":"male"}' where project_id=1 and id=2;
UPDATE values SET data='{"options":["male","female"],"default":"male"}' where project_id=1 and id=3;
After some hours i could get result with something like this in laravel framework:
$values = Value::where('project_id', $id)->get();
$sql = "";
foreach($request->fields as $field) {
if(!empty($field->default)) { //New default value is set
foreach($values as $value) {
$data = json_decode($value->data, true); /**data column as json object in mysql database **/
$data["default"] = $field->default;
$data = json_encode($data);
$sql .= "update ".DB::connection()->getDatabaseName().".values set data='".$data."' where id="."$value->id;";
}
}
}
DB::unprepared($sql);
but this code is not a good practice!
So my question is
Is there any ORM way to do this better?!

Answer 1

Here is an easy way to do it.
$values = Value::where('project_id', $id)->update(['data'=>$data]);
I found it from this link
Hope it helps.

Answer 2

$values = Value::where('project_id', $id)->get();
$sql = "";
foreach($request->fields as $field) {
if(!empty($field->default)) { //New default value is set
foreach($values as $value) {
$tmp=$value->data;
$tmp->default = $field->default;
$value->data = $tmp;
$value->save();
}
}
}
And in Value model use Mutator and Accessor, like this
public function getDataAttribute($value)
{
return json_decode($value);
}
public function setDataAttribute($value)
{
$this->attributes['data'] = json_encode($value);
}
See documentation http://laravel.com/docs/4.2/eloquent#accessors-and-mutators
