This is How to Add Attachments to Your Contact Form 7 Auto-Respond
As a WordPress developer, one of the most common requests I get from clients is the ability to add file attachments to their contact form auto-responses. Whether it's a product brochure, invoice, or other important document, being able to send these files automatically can save a ton of time and provide a better user experience.
However, setting up attachments in Contact Form 7 (CF7) – one of the most popular WordPress contact form plugins – isn't always straightforward. There are a few gotchas and best practices to be aware of to get it working seamlessly.
In this post, I'll walk you through the exact steps to add attachment functionality to your CF7 auto-responses, including using a relative file path, which is a key requirement. By the end, you'll have a rock-solid contact form that can send files to your customers with ease.
Let's dive in!
Understanding Contact Form 7 Attachments
Before we get started, it's important to understand how attachments work in CF7. When a user submits a contact form, they typically have the option to upload a file as part of their submission.
This file is then stored on your WordPress server in the /wp-content/uploads/
directory, with the file path following a structure like this:
/uploads/2023/03/my-file.pdf
Now, the tricky part is that when you configure your auto-response email, you need to tell CF7 where to find this file so it can be included in the email. This is where the relative file path comes in.
A relative file path means specifying the location of the file relative to the WordPress root directory, rather than the full absolute path. So, in the example above, the relative path would be:
uploads/2023/03/my-file.pdf
This is an important distinction, as absolute paths can sometimes break if your WordPress site is moved to a different server or domain.
Okay, now that we have the theory out of the way, let's walk through the step-by-step process.
Step 1: Configure Your Contact Form
First, we need to set up the contact form itself. If you haven't already, go to the CF7 plugin settings page and create a new form.
Within the form editor, you'll want to include a file upload field. This is typically done by adding the following shortcode to your form:
[file your-file]
You can customize the field label and other attributes as needed.
Step 2: Set Up the Auto-Response Email
Next, we need to configure the auto-response email that will be sent when the form is submitted. In the CF7 plugin settings, navigate to the "Mail" tab and you'll see the options for the "Mail (2)" section, which is the auto-response email.
In the "File Attachments" field, enter the relative file path of the file you want to attach. For example:
uploads/2023/03/my-file.pdf
If you have multiple files to attach, simply list them out separated by line breaks:
uploads/2023/03/my-file.pdf
uploads/2022/11/another-file.jpg
Make sure that the file paths you provide are correct and match the actual location of the files on your server.
Step 3: Test and Troubleshoot
Now it's time to test your form! Submit the contact form with a file attached and check your inbox for the auto-response email. Verify that the file is successfully attached.
If you're having trouble, double-check the following:
- File Path: Ensure that the relative file path you provided is correct and matches the actual location of the file on your server.
- File Permissions: Make sure the file has the correct permissions (typically 644 or 664) to be accessed by the web server.
- File Size: Contact Form 7 has a default file size limit of 1MB. If your file is larger, you may need to increase the
upload_max_filesize
and post_max_size
values in your PHP configuration.
- File Type: Confirm that the file type is supported by the email client and that the file extension is correct (e.g.,
.pdf
, .jpg
, .docx
).
If you're still having issues, you can try using the [file* your-file]
shortcode instead of [file your-file]
to make the file upload field a required field.
Bonus Tip: Customize the Attachment Filename
By default, the attachment filename in the auto-response email will be the same as the original file name uploaded by the user. However, you may want to customize the filename for a more professional or consistent look.
To do this, you can use the [_attachments]
mail tag in your auto-response email subject or body. This tag will output a list of attached files and their original filenames.
For example, you could use the following in your email subject line:
Your requested file: [_attachments]
This would display the attached filename in the email subject, like "Your requested file: my-file.pdf".
You can also use other mail tags like [your-name]
or [your-email]
to further customize the attachment filename, making it more relevant to the user.
