I'm using a class that extends TCPDF. This example opens a file and prints the contents of the file in the columns.
I've got data I'm pulling from a database and I'm going to run it through a loop and spit out html which will then be put in to the loop. But I was trying to avoid writing the results of the loop to a file, just so I can use this extension. I'd like to to just stick the results in to a variable and have that printed out.
What I need to concentrate on are the PrintChapter() and ChapterBody() functions. How do I get $content in the ChapterBody() function to accept a variable $html_grid instead of opening a file. If I replace $content with text directly, it works. If I replace $content with a function that doesn't take any arguments, that works also. But if I use $content = $html_grid (or any other variable) or $content = customFunction($text) { return $text; } doesn't work either.
Please help. Thanks!
