I'm trying to generate a table with inputs when files are selected in the filesinput. The table generation works, but I'm having trouble with getting the strings to accept the php code. The code enclosed by <?php ?> gets converted to html forms when compiling, and JavaScript shouldn't have a problem with HTML as strings, so I don't understand what's going wrong here.
