This is a program to allow an upload of a pdf file. The pdf file will be checked to see if it is a pdf, checked to make sure the file doesn’t exist. Then if all is well it is added to an array and a html document is generated based on all of the pdf files located on the server. I can’t figure out why this dosen’t work. When I trim the program down to the basics where a pdf can be uploaded, no checks are made, and the file is rewritten with php code without using an array but rather previous_contents of the file and then just adding the new file to the html document, the program works. When I add the extra features it wont work. Wont work means when I upload the file the result is a blank white page.
This code is where the user uploads the file(this is just a snippit, all the proper html tags do exist on the page:
[code]
Please choose a file:
Make sure your file name is #.pdf. (Example: Bugle #71 should be named 71.pdf) After uploading you will be logged out [/code]
Thank you.
This is upload.php this is where the problem is
