    I get an error “A variable mismatch has been detected” when a user tries to save the form and a field which needs to be validated is empty. When I remove the validation from the field, the form is being saved. I found the following in the file “pdb_debugging_65e88af9425eb.txt”


    <header>[10/22/25 3:19pm UTC]</header> <pre>trim(): Passing null to parameter #1 ($string) of type string is deprecated</pre><footer>in /home/xyz/wp-content/plugins/participants-database/classes/xnau_FormValidation.php on line 429</footer>

    Can you investigate on this behaviour?
    participants-database v.2.7.7
    pdb-image-expansion v.1.7.6
    pdb-login v2.2

    Thanks, Phil

    What is the intended effect of the validation? What is the validation setting for the field?

    The item in the error log is not causing a problem, it’s only a warning.

    Its hard to explain without screenshots. The validation is for a required filed like “address” that needs to be filled out before the form can be submitted. if the form does have one required field and this is not filled in, the error occurs.

    I found out, that the validation does not work when the url ends with “?pid=KTCQOMLVV67VHGTJ”. But when the form is submitted the url changes to “?sess=e2c492dca29fa9d5975a8d00bc1d7a98” at the ending. Then the validation works as usual.

    So, from what I am seeing here, the validation is working, if a required field is left empty, it will trigger a validation error. I don’t recognize the validation error message, so this is probably the custom validation message you have set for the required field.

    So, I’m sorry, but I still don’t understand the problem. I’m trying to understand what you want it to do that it isn’t doing.

    There seems to have been a temporary problem with either the server or something else, but now everything is back to normal and working fine. Sorry for the inconvenience.
