First update after 20 december 2024 needs extra attention!

Conditional Fields 2.5.5 and later use new folder and file names.
As a result, the plugin will deactivated automatically the first time that you update from version 2.5.4.
Please make sure to activate the plugin manually after the update.

Conditional file attachments

The file field is a supported conditional field. But apart from simply showing/hiding groups based on the fact if a file is selected or not, you can also add files conditionally.

Attach files from your media library conditionally

Take this form as an example:

Select file: [select "file-1" "file-2" "file-3"]
[group g1]file-1 will be emailed to you[/group]
[group g2]file-2 will be emailed to you[/group]
[group g3]file-3 will be emailed to you[/group]
[submit]

Now in the Mail tab, in the “File attachments” field enter this:

[g1]
uploads/2019/07/file-1.pdf
[/g1]
[g2]
uploads/2019/07/file-2.pdf
[/g2]
[g3]
uploads/2019/07/file-3.pdf
[/g3]

Note that, to add files from your library, you need to get the absolute path. i.e.: https://example.com/wp-content/uploads/2019/07/file-1.pdf, and only keep the part after https://example.com/wp-content/. So in this case the part you keep would be: uploads/2019/07/file-1.pdf

For security reasons, you are not allowed to add full URLs as file attachments. See CF7 documentation.

Form

    Select files:

    file-1 will be emailed to you

    file-2 will be emailed to you

    file-3 will be emailed to you

    Form Code

    Select files: [select menu-1 multiple "file-1" "file-2" "file-3"]
    [group g1]file-1 will be emailed to you[/group]
    [group g2]file-2 will be emailed to you[/group]
    [group g3]file-3 will be emailed to you[/group]
    [submit]

    Conditional Fields (Text)

    show [g1] if [menu-1] equals "file-1"
    show [g2] if [menu-1] equals "file-2"
    show [g3] if [menu-1] equals "file-3"

    Attach user uploaded files

    In most cases you would not need conditional logic to handle files uploaded by the user. But I’ll add an example for completeness.

    The form:

    File 1: [file file-1]
    File 2: [file file-2]
    File 3: [file file-3]
    [submit]

    In the “File attachments” field add this:

    [file-1]
    [file-2]
    [file-3]

    Only non-empty file fields will be added to attachments, so no need to specify conditions in this case. This is the default CF7 behavior.
