I have this error message when opening a form: Warning: Invalid argument supplied for foreach() in /opt/processmaker/workflow/engine/classes/class.pmDynaform.php on line 539

It doesn't always happen and even if I remove all my javascript code, it still shows this error. I don,t know what triggers this error, any idea?

What version of PM are you using? In version 3.2.1 (which was the last version of PM to use the class.pmDynaform.php file, I don't see a foreach on line 539. Also are you using Bitnami or a manual install? Also what version of PHP do you have installed?

I'm using version 3.1.3. Manual Install and our PHP version is 5.6.32

Can you post your /opt/processmaker/workflow/engine/classes/class.pmDynaform.php file?

When I look in my 3.1.3 installation, I'm seeing the following code in line 539:

Code: Select all

$oCriteriaAppDocument->add(AppDocumentPeer::APP_DOC_STATUS, 'ACTIVE');

Line 539 is: foreach ($rows as $keyRow => $row) {

Code: Select all

//grid
                if ($key === "type" && ($value === "grid")) {

                        //rows

That is bizarre. In my installation, that is line 687. Is this an upgraded version of PM? If so, you didn't upgrade that file correctly.

You probably should download the ProcessMaker source code (the tar.gz file) again and redo the upgrade procedure.

[stevensi1018]

I don't think we've upgrade anything from this version. Thanks anyway, I'll find a way to bypass that in my form, don't really want to reinstall since a lot can go wrong and it almost never happen
