[Proper syntax for referencing PHP variable in TCPDF code]

I am generating a PDF file using POST method from an HTML form for the values.  I can't seem to get the syntax right or something.  When I enter a placeholder in the PHP code for TCPDF, I still do not see my value on the generated file.

 

Example:  My field is called $hidformtitle which is just a string.

Here is what I am putting into the pdf script (I'm just using example_014.php from TCPDF for proof of concept to test with.):

 

// Form Subject Test
$pdf->Cell(35, 5, 'Form Title:');
$pdf->TextField($_POST ['hidformtitle'], 50, 5);
$pdf->Ln(6);

 

Could someone provide an example to me of how you would insert this a field using the same method.  It does not have to relate in any way to what I've posted here as far as the code goes.  I honestly just don't know what I'm doing any more and need an example.

 

My sanity may depend on this as I started out thinking this is pretty simple stuff and now I'm not sure of anything.

 

THANK YOU!
