Advanced Forms for ACF

Frequently asked questions

Can I have multiple forms on the same page?

Yes, you may have multiple forms on the same page.

Is it possible to handle submissions without a page reload (using AJAX)?

Advanced Forms can handle submissions without a reload using AJAX. Activate it for your form using the ajax display argument.

Can users access the media library via Advanced Forms?

If a user is logged in and has permission to access the media library, upload fields should default to using the media library. This can be configured using the uploader display argument.

How can I restrict the available media when using the uploader?

Restrictions on available media is best handled on the WordPress level rather than within Advanced Forms. There are some guides online on how to achieve this as well as some plugins which can help. See this article for both plugin- and code-based examples.

Why does the image/file upload field change when a user is logged in or not?

This discrepancy is due to how ACF handles image uploads in response to WordPress. When a user is not logged or lacks the relevant permissions (typically the upload_files capability), the default/basic HTML upload field is rendered without the necessary scripts to stylize it and use the WP media uploader. This is built into ACF's field rendering logic and it aligns with WordPress' core requirements for using the media library.

The basic HTML upload field does render differently to the stylised version which is why they appear different and require their own CSS to style. You may wish to add some custom CSS for the basic HTML upload field as per this example on CSS-Tricks.

If you prefer to use the basic HTML uploader for a consistent experience for all users, you can configure this in the form args by setting the uploader display option to basic. This will disable the media library UI but doesn't require special permissions or a logged in status. See Display options for examples on how to do so with both the shortcode and theadvanced_forms() function.

Why is my success message not showing after submission?

This issue is often caused by page caching provided either by your host or a plugin on your site. We recommend disabling the cache for the page with your form or to create a custom “thank you” page and redirecting to that after submission.

I’m seeing weird behaviour with my form that has a large number of fields. What could be wrong?

If your form has a very large number of fields there is a risk that you will run into limits set by PHP. If the form is not working at all or you’re seeing weird behaviour, we recommend increasing the max_input_vars setting in PHP.

ACF's gallery field uses the WP media uploader under the hood which means it requires a signed in user to work. The user must also have the right capabilities to access the media library. If you want your form to be accessible for non-authenticated users as well, we recommend replacing the gallery field with a repeater of image fields.

Can I use Advanced Forms to list a user's posts for editing or deleting?

Using Advanced Forms Pro, a form can be used to both create and edit posts but the plugin only handles the form itself – it doesn't provide utilities for listing or deleting posts.

Displaying lists of posts is a bit outside the scope of the plugin but can be achieved a number of different ways. The right way for your project will depend on what kind of theme setup you have in place. e.g; if you have a custom coded theme, you have the flexibility of writing WordPress queries and template loops to suit the situation but if you are using a page builder, you may have to adapt using the tools provided.

The basic idea, however, is simple: you simply need to configure your theme to show all posts which the user is an author for (Advanced Forms Pro will automatically make them the author when creating a post) and then on each individual post page you can use the [advanced_form] shortcode to render a form for editing the current post. See Using a form to edit the current post.

Alternatively, you may wish to have a single dedicated page with your form and use a custom URL parameter to pass a post ID to the form. See Using a URL parameter to control which post is being edited.

What about deleting posts?

Again, this is something you'll need to build into your theme/implementation but consider using WordPress' get_delete_post_link() function within a query loop to delete the current post or you can pass a specific post ID to the function.

Can I set the license key using WP CLI?

No, this is not currently possible.

Can I export form entries?

There isn't currently any built in mechanism for exporting form entries but entries are stored as posts with their own ACF field data so this can be done using tools specifically designed to export data from WordPress.

WP All Export is a fantastic option for exporting posts.

Can I generate a PDF from a form submission?

PDF generation is not a built-in feature of the plugin at this stage. However, you may write your own code to hook into the form submission, generate a PDF, and attach the PDF to the form using the af/form/email/attachments filter. The basic process will be as follows:

  1. Generate a PDF via PHP with field values retrieved using af_get_field().
  2. Save the PDF to a file on the server.
  3. Return the file path from the filter to attach it to the email.

Can I use Advanced Forms to enhance WooCommerce?

Advanced Forms has no integration with WooCommerce at this time so it cannot be used to enhance any WooCommerce forms such as checkout, account management, etc.

The plugin does offer a rich set of actions and filters so you may well be able to get creative and use it to collect information that you then inject into WooCommerce data structures.

Can I display the user's password in a form field?

No, it isn't possible to display a user's password. This is because WordPress does not store passwords in plain text but instead, stores them as a hash which cannot be reversed. This helps to prevent the risk of passwords being leaked when a hacker gains access to the database.

Does the MailChimp integration support tags?

See How to add tags using PHP.

How do I redirect to another page after submission?

You can pass a URL to the redirect display argument when displaying a form.

How do I change the submit button text?

See Customizing how the form renders.

How do I connect my form to an external service?

Advanced Forms Pro has built-in integrations with Slack, Mailchimp, and thousands of other services through Zapier. If you need to integrate with a service that is not supported, you may build a custom integration. This normally entails writing a custom submission handler which collects form data and sends it to a third-party API.

How do I remove the default styles for a form?

Advanced Forms will enqueue default styles from both ACF and its own styles. To dequeue all of them, use the following snippet:
