Adding a Basic File Upload Field

Prevent large uploads with limit:mb:

[file your-file limit:2mb]

Restricts files to 2MB.

2. Allow Specific File Types

Accept only images or PDFs:

[file your-file filetypes:jpg|png|pdf]

3. Enable Multiple Uploads

Let users attach several files:

[file your-file multiple]

4. Customize Button Text

Improve UX with friendly labels:

[file your-file id:cv-upload "Upload Your CV"]

Example: Job Application Form

[text your-name]
[email your-email]
[file cv-upload filetypes:pdf|doc limit:5mb "Attach Resume (PDF/DOC)"]
[submit "Apply"]

Pro Tips

• Security: CF7 automatically sanitizes uploaded files.
• Storage: Files are stored temporarily in /wp-content/uploads/wpcf7_uploads/ (auto-deleted). Use plugins like Flamingo to save them permanently.
