Join Jon Peck for an in-depth discussion in this video Uploading files, part of Up and Running with Symfony2 for PHP (2014).
Well, if you feel like there hasn't been…enough coding in this course, buckle up.…Things are about to get real.…One of the helpful parts of HTTP foundation is uploaded file…which represents a file uploaded through a form.…We're going to be using uploaded file…in the issue entity to facilitate cover uploads.…Uploaded file comes with a number of helper methods…including move which takes a target…directory and optional name for file.…Move, as you probably guessed,…moves a file to a new location.…We'll also be using get client original name…to get the original file name of the uploaded file.…
Depending on your security or organizational needs,…it may makes sense to generate a file name instead.…We're going to be making a number…of changes necessary for uploading a file…but individually they're actually quiet straightforward.…Let's walk through them first to the high level.…We'll start with the issue entity and add methods…to get passed to our upload directories while the absolute…path on disk and the relative path for web operations.…

Q: When trying to access the application, I receive an error stating "This script is only accessible from localhost." How can I get around this restriction?
A: The development front controller and configuration scripts are protected by default to only allow access from the localhost. Refer to the video titled “Exploring the Symfony layout” to see how to disable this security.
Q: I specified the wrong database credentials and got an "Access denied for user" error from doctrine. How can I fix the database configuration?
<div>A: The most likely cause is a typo or misconfiguration in the Symfony parameters file, which you can find at ./symfony/app/config/parameters.yml. This file is typically generated during installation using an interactive wizard.</div><div> </div><div>Symfony requires read and write access to a MySQL database, and needs to know how to connect to the database. Therefore, you'll need to specify a username, password, port (if nonstandard), host, and database name. The credentials to your individual development environment are likely different than the ones used in the course; please use your best judgment in determining the correct values. After making a change, verify the configuration by using a web browser to navigate to /symfony/web/config.php, then click “Configure your Symfony Application online” at the bottom of the page.</div>
Q: How can I configure PHP's time zone?
<div>A: You'll need to edit PHP's configuration to specify a time zone. The <em></em><a href="http://www.lynda.com/Apache-tutorials/Up-Running-Linux-PHP-Developers/158372-2.html"><em>Up and Running with Linux for PHP</em> <em>Developers</em></a> PHP configuration can be modified by editing the custom configuration:</div><div> </div><div>sudoedit /etc/php5/mods-available/custom.ini</div><div> </div><div> If you have a different development environment, determine the location of your php.ini configuration file. Specify a date.timezone, such as: </div><div> </div><div>date.timezone = America/Los_Angeles</div><div> </div><div>Then restart the server using: </div><div> </div><div>sudo service apache2 restart</div><div> </div><div>A full list of supported timezones can be found at <a target="_blank" href="http://php.net/manual/en/timezones.php">http://php.net/manual/en/timezones.php</a>.</div><div> </div>
