I have a form whose On Submit section has a custom code action and a TCPDF action. The custom code retrieves multiple rows from a database and formats them into an HTML table. The TCPDF Contents section is blank, so it should create a pdf document containing this table. With the View option in TCPDF set to "save to server", the table is displayed correctly on the screen, but is followed by this message:
Warning: Invalid argument supplied for foreach() in /.......components/com_chronoforms5/chronoforms/actions/tcpdf/tcpdf/tcpdf.php on line 23773
Same message is repeated with "on line 23805".
No pdf file is generated.
SInce the table is displayed correctly, I think my custom code is retrieving the rows and formatting the table correctly. The only "foreach" in my custom code processes the retrieved rows, and even if I remove it and retrieve and display only a single row, I get the same message. Any idea what the problem could be?
