I am currently working on a plugin for WordPress involving lots of .php files. I see that for my AddShift.php file, we are successfully importing the blog header using the following line of code:
include("../../../wp-blog-header.php");
However, when I try to do the same thing in my ajax_cal_split.php file, I get the following error:
Warning: include(./wp-blog-header.php) [function.include]: failed to open stream: No such file or directory in /opt/lampp/htdocs/sandboxj/blog/wp-content/plugins/Shifty/ajax_cal_split.php on line 11
Warning: include() [function.include]: Failed opening './wp-blog-header.php' for inclusion (include_path='.:/opt/lampp/lib/php') in /opt/lampp/htdocs/sandboxj/blog/wp-content/plugins/Shifty/ajax_cal_split.php on line 11
Line 11 of course says
include("../../../wp-blog-header.php");
Is there any reason for this call to work on one .php file and not another, when they reside in the same directory?
Yes – I believe wordpress operates a security mechanism on content in the wp-content directory, I had the same problem with themes. The workaround I used was to include with absolute path names.
