CI newbie needs help with page not rendering after process is sent through more then 2 functions

[eluser]tammysk[/eluser]
Hi I'm relatively new to CI and I've run across this issue a couple times.

the task i'm working on loads a main index, when a link is clicked a popup which is used to gather filters to display a view appears. once it is submitted another view with a form appears. on submission of this form it does several inserts into databases and then redirected to a generatePDF function. after output of the pdf another database insert is done and its redirected back to the index.

the redirects are all done with

Code:

$this->function($data);

I've checked all the databases and all the info is there that should of been inserted, and the pdf file is in the files folder but all it renders is a blank page. I placed a echo statement at the very end of my index and it echos the page image that should of displayed. So I know its getting there, just unsure why it won't render.

In other cases when this has happened if I placed a return; after it It would work but even that isn't working this time.

Any help would be greatly appreciated.

Show your code.

there is more but its a few thousand lines in total

this is at the end of the pdf function

Code:

to make more sense of this the createNewa is the popup. its redirected through post to the createNew function which near the bottom has the

Code:

$this->createAgentPDF();

redirect. then at the bottom of the pdf in the if statement is the redirect back to the index.

[eluser]tammysk[/eluser]
this is the image of the echo at the end of the index function. but it wont render through the load->view

[eluser]tammysk[/eluser]
Solved.
