Support » Plugin: Ninja Forms Contact Form - The Drag and Drop Form Builder for WordPress » Duplicating form doesn’t work [UNRESOLVED]

  • Resolved thelandman


    This thread was previously marked resolved but it’s not:

    Running the latest version of WordPress. On a WordPress MU environment.

    I have approximately 30 forms created. Attempting to duplicate results in the form entry being duplicated but the form fields are not copied over to the duplicate.

    The information under “Emails & Actions” and “Advanced” seems to be duplicated.

    For now I’ve resorted to exporting/importing a form file to create a duplicate.

    I am sorry, but I am unable to replicate your issue locally. Can you contact our official support channel, so we can take a closer look at this issue?

    I too can confirm that, once updated, Ninja Forms cannot duplicate older forms properly. New forms can be duplicated, but if like us you have over a hundred older forms, this is a big problem requiring all older forms to be rebuilt instead of copied.

    Once duplicated, the new form contains fields, but each field has a question mark (?) where the field name should be. When clicked (to edit form field), the field shows the following message:

    Unknown. Field type "" not found

    @chrslcy This is not the normal behavior of the forms. Can you contact the official Ninja Forms support at so we can take a look into this issue on your site.



    I did contact the official Ninja Forms support, and this is what they said:

    “I logged into the site and looked at the database.

    This is 100% a data level error. Several of their forms have no data associated with their fields in the nf3_fields data table, and that’s why they appear as “unknown” when they’re duplicated.

    Export/Import builds a clone of the entire form, which exists (temporarily) as a JSON file and is then re-constructed into data. However, duplicate actually copies values directly from the database and reallocates them to the newly generated form. So, if the data is corrupted before duplication begins, it will always be broken after duplication has taken place.”

    Which basically suggests there’s nothing can be done. However, there were no reports of problems with duplicating forms before the upgrade.
