First-time poster--will try to be fully informative. Because I'm a nonexpert, I'll probably overexplain some obvious things in an effort to be clear.
I am running an online research study using a set of php scripts (index file with conditional statements that load a whole series of php pages). Because there are many pages in different categories, I have them in separate subdirectories. For example, the parent directory is called "Seg" and the subdirectories include "Audio," "Visual," "Images," and "Sound."
The index file, in Seg, will load a page (C1B.php) from Audio, which should pull a header and a data-managing file from Seg, as well as an image from Images and sound files from Sound. Within C1B.php, I use relative file references, so--
If I test a single page from the Audio directory by typing its full address directly into the browser address line, everything loads with no problem. However, when I try to run the program using the index file, then the invocation of the same page produces error messages:
Warning: main(../header.php) [function.main]: failed to open stream: No such file or directory in /home/.napoli/name/site.org/studies/seg/visual/vqaire1_N3C.php on line 2
Warning: main() [function.include]: Failed opening '../header.php' for inclusion (include_path='.:/usr/local/lib/php') in /home/.napoli/name/site.org/studies/seg/visual/vqaire1_N3C.php on line 2
Can anyone help me understand why this happens so I can figure out how to fix it? I would really prefer NOT to go to absolute paths if possible. Thank you!!
