A view that I've been using for years is suddenly throwing this error:

Warning: array_map(): Expected parameter 2 to be an array, null given in /home/writiol6/public_html/wp-content/plugins/cred-frontend-editor/vendor/toolset/toolset-common/toolset-forms/classes/class.conditional.php on line 325

I don't even know where to start to figure this out.

Help!

This is the page where it is happening:

Hello,

You are using nested shortcodes:

[wpv-if...]
[wpv-conditional ...]
...
[/wpv-conditional]
[/wpv-if]

And the [wpv-if] shortcode is retired, I suggest you try to use [wpv-conditional] shortocde instead of it, for example, please this one from:

[wpv-if url="wpcf-answer1" evaluate="!empty($url)"]
[wpv-conditional if="( $(wpcf-answer1) eq '[types field='question1rightanswer' id='$test'][/types]' )"]
[add-to-total][types field='points' id='$test'][/types] * 1[/add-to-total]
[/wpv-conditional][/wpv-if]

To:

[wpv-conditional if=" (!empty($wpcf-answer1) ) AND ( $(wpcf-answer1) eq '[types field='question1rightanswer' id='$test'][/types]' )"]
[add-to-total][types field='points' id='$test'][/types] * 1[/add-to-total]
[/wpv-conditional]

Thanks. But I just realized that the error is actually happening on a page that is calling a cred form - and I'm not seeing the retired wpv-if on that page. Here is the code for the cred for that is throwing the errors:

[credform class='cred-form cred-keep-original']

[cred_field field='form_messages' value='']

[Luo Yang]

You are using quite complicated codes, please provide a copy of your website in below private message box, you can put the package files in your own google drive disk, share the link only, also point out the problem page URL and view URL, I need to test and debug it in my localhost, thanks
https://toolset.com/faq/provide-supporters-copy-site/

[Luo Yang]

Thanks for the details, I can download the files, will update here if find anything

[Luo Yang]

Please try these:
Edit the post form "Answer Edit Form":
hidden link

Replace all [cred_show_group] ... [/cred_show_group]
With:
[wpv-conditional] ... [/wpv-conditional]

And test again.

The [cred_show_group] shortcode is for triggering when user change inputs in Toolset post form, but in your case, it is checking the related posts custom field value, so you need to use [wpv-conditional] ... [/wpv-conditional] shortcode instead of [cred_show_group] ... [/cred_show_group]

I have tried it in my locahost, it works fine with your duplicator package

[eliseD-2]

Thanks so much - that seems to have worked!

(I'm not sure why it changed - the original code has been working for several years)

Anyway - thanks!!!!

[eliseD-2]

My issue is resolved now. Thank you!
