Hi Marc ,
I am really sorry for the delay. I had my lab exams going on. I did compare the libraries/export/pdf.php with libraries/export/htmlword.php. I have written the function PMA_exportStructure() for pdf export and its working, printing the structure. But the problem is that the "pdf_structure_or_data" option value is "data". It has to be changed to "data_and_structure".I inspected the source code, this is the problematic code
<input type="hidden" value="data" name="pdf_structure_or_data">.
So i am trying to pin point the script where the format specific options
are set. Any help would be appreciated.
