TCPDF fails when there is no file upload - looking for ways around it

Hi all,
​
So i have added a image file upload to my server which then writes onto my TCPDF file and stores locally. All works perfectly when there is a physical file uploaded, however, for obvious reasons the TCPDF fails when there is no file upload as it cannot find the non-existent image file.
​
I have tried to seperate the TCPDF to store differently depending on file upload success/failure - however, file upload fail is not triggered by not having a file uploaded so therefore that option does not work.
​
Do you have any ideas around this, or a little trick I can implement to ensure even though no file is uploaded the TCPDF still generates without including the file upload?
​
Many Thanks,

Use a switch. If {var.empty:fileuploadaction} is true then return probably just "No image uploaded" but if false then put your image tag code. Use {var:switchname} in your TCPDF action in place of the image tag you have now.

Hi Healy,
​
Thanks very much - can you advise where i am falling short - I can't attach a screenshot, upload is not working on the forum for me.
​
My Upload is called Upload93,
My switch is called tcpdfswitch
​
In my switch data provider i have: {var.empty:upload93}
​
In my values i have:
​
1:"No passport uploaded"
2:"passport found"
​
on my TCpDF i have:
<h3 style="text-align: center;">{var:tcpdfswitch}</h3>
​
My Debug gives me this:
​
​

[upload93] => Array
        (
            [path] => /home/iregcdvg/public_html/components/com_chronoforms6/chronoforms/uploads/
            [file95] => Array
                (
                    [extensions] => Array
                        (
                            [0] => jpg
                            [1] => jpeg
                            [2] => png
                            [3] => gif
                            [4] => pdf
                            [5] => doc
                            [6] => docx
                            [7] => txt
                            [8] => zip
                        )

                    [info] => File is not present.
                )

            [var] => Array
                (
                )

        )

    [tcpdfswitch] => Array
        (
            [finished] => 1
            [var] => 
        )

However, nothing prints on my tcpdf, where have I gone wrong?
​
Many Thanks,

Working like a dream, thank you very much🙂
