Hello,
I have a similar issue asked here:
http://stackoverflow.com/questions/2409406/call-to-drupal-render-returns-null
but on my case, I think the function is not called since if I put a
file_put_contents before the access check, then nothing is written to that
temp-file.
Before call the drupal_render function I check the element passed is
well-formed, and apparently it is.
#foo_site_theme.inc
function theme_citroen_site_entity($variables) {
file_put_contents("/tmp/community.log", "\nSTART\n");
file_put_contents("/tmp/community.log", print_r($variables['element'],
true), FILE_APPEND);
return drupal_render($variables['element']);
}
#common.inc
function drupal_render(&$elements) {
file_put_contents("/tmp/community.log", "\nhola caracola\n", FILE_APPEND);
// Early-return nothing if user does not have access.
if (empty($elements) || (isset($elements['#access']) &&
!$elements['#access'])) {
return '';
}
...
...
...
}
So, even if my problem could be about the access permission, I wonder I might
see the string "hola caracola" at this temp-log-file.
The only conclusion I can get is the function drupal_render is never called,
what surprises me and I can't understand why.
Also I tried to put a syntax error inside drupal_render function, and drupal
works without errors.
If I put the same typo inside theme_citroen_site_entity function, then I can
see this typo-error
Anybody could point me to the right direction?
Thanks in advance.
