One particularly perplexing issue arises when you successfully send a POST request with multipart/form-data, receive a 200 response, but notice that the file doesn't get saved to the intended directory. If you're facing this problem, don't worry—you're not alone. In this post, we’ll explore the solution step-by-step. Understanding the Problem You are using the Vich Uploader Bundle along with Api Platform to handle file uploads. Your current setup allows you to upload a file and returns the expected response indicating success. However, the uploaded file doesn't persist, and the generated filename remains unchanged. You’re left with no error messages and no clear idea of where the failure occurred. Here's what your original setup looks like: Vich Uploader Mapping [[See Video to Reveal this Text or Code Snippet]] POST Request Sample [[See Video to Reveal this Text or Code Snippet]] Cause of the Issue The problem arises primarily from how the Doctrine event listener works within the VichUploaderBundle. The bundle listens for prePersist and preUpdate events to handle file uploads. If no related changes are detected in the persistent properties of your entity (in this case, the Organization entity), the upload listener does not trigger to save the uploaded file to the designated directory. Key Points to Note: Persistent Properties: If no properties of your entity are updated during the upload process, Doctrine doesn’t register any changes. No Trigger for File Handling: Consequently, the Vich Uploader won't handle the file upload. Implementing the Solution To resolve this issue, you need to ensure that a change occurs in a persistent property whenever a file is uploaded. A common approach is to introduce an updatedAt property, which you can update each time a file is uploaded. Step 1: Update Your Entity with updatedAt Here’s how to modify your Organization entity: [[See Video to Reveal this Text or Code Snippet]] Step 2: Modify the Upload Action Next, ensure that when a file is uploaded, you call the updateLogo method on the Organization entity. Update your CreateOrganizationLogoAction class as follows: [[See Video to Reveal this Text or Code Snippet]] Conclusion By adding the updatedAt property and modifying how you handle the file upload in the action, you make sure that each file upload triggers a change in the persistent properties of the entity. This approach ensures that the Vich Uploader Bundle can manage the file properly, moving it to the designated directory as intended. Feel free to implement this solution in your project, and welcome the ease of managing file uploads with Symfony!
