Profiles and Media

Goal

This snapshot advances Keystone Gazette by teaching you to show author profiles and accept constrained avatar uploads.

Every numbered folder is a complete app. Run this stage independently, then compare it with the previous folder.

Prerequisites

Use PHP 8.2+, Composer, and Docker for MySQL stages.

Port 8002 must be free. Copy .env.example before starting database stages.

• PHP 8.2+ and Composer
• A code editor and terminal
• Docker from part 4 onward

Concepts

Upload endpoints must check type and size and store safe filenames.

Keep controllers thin: forms accept input, Doctrine entities enforce rules, and Twig escapes output by default.

Walkthrough

Protect profile editing and serve uploads.

Read the example, then open the matching snapshot. The repository includes the surrounding setup and error handling.

if (!\in_array($file->getMimeType(), ['image/jpeg','image/png','image/webp'], true)) { throw new BadRequestHttpException(); }

Run and verify

Enter 08-Profiles-And-Media, install Composer deps, copy .env.example, and start the Symfony server on port 8002.

Open http://127.0.0.1:8002. Watch the terminal for validation and database errors.

docker compose up -d
git clone https://github.com/michaeldunga1/fcc-symfony-blog.git
cd fcc-symfony-blog/08-Profiles-And-Media
composer install
cp .env.example .env
symfony server:start --port=8002 --no-tls
# or: php -S 127.0.0.1:8002 -t public

Troubleshooting

Confirm multipart enctype and field name.

For database failures, confirm Docker and the keystone_NN name when applicable. Never commit .env or vendor.

• Read the first error first
• Restart after environment changes
• Never commit secrets

Try this

Upload a valid image, then reject a text file.

Test a happy path and one invalid or unauthorized request.

• Make one small change
• Test it in the browser
• Compare with the next snapshot only after it works
