Why ? Re: Dynamic Properties in PHP 8.2 2 Weeks Ago by Dani > This obviously does not make sense to do if you want to create or work with a User object or something of that sort. I realize that in my previous post I incorrectly gave the example of `$user = new stdClass(); $user->nickname = 'Dani';`.

Re: How to show visa info based on country selection in a travel form? 2 Weeks Ago by Biiim I felt like some fun, so I just put together an example for you using CDN's and bootstrap 5. From what you are talking about you probably want to put some of that logic into the Javascript and not need to send a server request for each one, I usually do this kind of thing with javascript objects/arrays (eg `settings['GB']['visa_req'] = false;… Re: How to show visa info based on country selection in a travel form? 3 Weeks Ago by Dani I have moved your post into the web development forum instead of the advertising/marketing forum where it was and tagged it appropriately. Can you please provide the Javascript code as well as PHP code that is buggy so that we can help diagnose this for you. For example, if the JSON response is empty, it is most likely because of a bug in the … How to show visa info based on country selection in a travel form? 3 Weeks Ago by eservices I’m working on a travel planning form that adjusts based on the selected nationality.

For example, I asked it to generate a Laravel controller with French comments, and the output was both functional and easy to … Re: Safely upload a file 2 Weeks Ago by Dani I realize I could have done better when coming up with a safe name. As it stands, a file uploaded that has a file name in non-Latin characters will just end up with a bunch of underscores. I’m not even sure if that suffices as a file name, but for sure there will be collisions as multiple files are attempting to be saved with the same _ name. Re: Safely upload a file 1 Week Ago by john_111 You should display a message acknowledging the upload was successful or that it failed (and why it failed), and perhaps it's new name. Re: Safely upload a file 1 Week Ago by Dani I feel like that's part of the UI that would be very different depending upon the context. For example, what would the message look like? This is meant to just be a backend utility function. Re: Flood control using Redis 2 Weeks Ago by Dani Status update: we now use Cloudflare’s free rate limiting functionality.

Re: My php is showing wrong results of time difference 1 Month Ago by Dani I am confused when you say the HTML time picker input box can be set to 20:00 for time in and 5:00 for time out, because `<input type="time" ...>` only allows the end-user to specify a time, not a time and date combination. Should it always be assumed that if the time out is earlier than the time in, that it is the next day? … Re: My php is showing wrong results of time difference 1 Month Ago by Dani In other words, if you just need days or hours you can do something like `$diff->d` or `$diff->h` (All properties available [here](https://www.php.net/manual/en/class.dateinterval.php), but if you want to calculate a runner's start time and end time and then do something like "You ran the race in 08:33:56!" then you could use the `… Re: How to connect to the Pinterest API using PHP? 1 Month Ago by geekinformatic Hey!
