Converting a carbon date to mysql timestamp.

Question

I have a timestamp variable column in a mysql database. Trying to convert a carbon timestamp to something that I can input there, but Carbon::now() only returns a Carbon object and when I try to use the timestamp string of the Carbon object, it does not register in mysql.

public function store(CreateArticleRequest $request){         $input = $request->all();          var_dump($input); // JUST SO YOU CAN SEE         $input['published_at'] = Carbon::now();          var_dump($input); // JUST SO YOU CAN SEE         Article::create($input);    } 

My first var dump is like so:

array (size=4)   '_token' => string 'Wy67a4hWxrnfiGz61wmXfYCSjAdldv26wOJiLWNc' (length=40)   'title' => string 'ASDFasdf' (length=8)   'body' => string 'asdfasdf' (length=8)   'published_at' => string '2015-08-26' (length=10)   

My second var dump is like so.

The mysql column relating to "published_at" is a timestamp variable. How an I suppose to convert this from a Carbon Object?

Thanks in advance.

Answer 1

The short answer is that toDateTimeString() is what you're looking for:

$input['published_at'] = Carbon::now()->toDateTimeString(); 

See http://carbon.nesbot.com/docs/ for more options, including toDateString() if you just want the date part and not the time.

But an even better way to handle it would be to let Laravel handle casting the date value to/from a Carbon object for you. See https://laravel.com/docs/5.4/eloquent-mutators#date-mutators.

The problem is in your date string, for example, you have this:

public function setCrbDateAttribute($value) {      $this->attributes['crb_date'] = \Carbon\Carbon::createFromFormat('d-m-Y h:i', $value); } 

Now, if there is a date like 10-12-2014 then this error will occur because the hour and minute is missing. So you make sure that the date contains all the pars and also make sure that the date string contains - as a separator not /.

In other words, check the $value before you use Carbon and make sure your date string contains exactly the same formatted string you've used in the method.

This also happens in an accessor method, so check the date value first before you use it in Carbon::createFromFormat().

If you are getting the date from user input then validate the date before using it using date or date_format:format rule, check the validation here.
