drupal 7 - Need to change node's path to CCK value -


i have content type has been turned feature named "earth news". includes optional cck field called "source url". when cck field not blank want site visitor able click on teaser , go straight url.

i've added following preprocess function .module file feature:

function earth_news_preprocess_node(&$vars) {   $node = node_load($vars['nid']);   $path = drupal_lookup_path('alias','node/' . $node->nid);   $url = $node->field_se_news_source['und'][0]['url'];    path_save(array($path,$url)); }

the path_save throwing fatal error:

only variables can passed reference

am on right path? what's error about?

thanks.

the error caused fact path_save() expecting single argument passed reference. in such case, cannot use literal array; pass variable containing array, or value returned function returns reference, value expected argument needs associative array containing following keys:

  • source: internal system path
  • alias: url alias
  • pid: (optional) unique path alias identifier
  • language: (optional) language of alias

in case, code should following one.

function earth_news_preprocess_node(&$vars) {   $node = $vars['node'];   $path = array(     'alias' => drupal_lookup_path('alias','node/' . $node->nid),     // can use following line instead of previous one.     // 'alias' => drupal_get_path_alias('node/' . $node->nid),     'source' => $node->field_se_news_source['und'][0]['url'],   );    path_save($path); }

as side note, template_preprocess_node() makes available node object $vars['node']; there no need load node.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

javascript - Clean way to programmatically use CSS transitions from JS? -

as title implies, there proper way set initial css properties (or class) , tell browser transition these value? for example ( fiddle ): var el = document.queryselector('div'), st = el.style; st.opacity = 0; st.transition = 'opacity 2s'; st.opacity = 1; this not animate opacity of element in chrome 29/firefox 23. because ( source ): [...] you’ll find if apply both sets of properties, 1 after other, browser tries optimize property changes, ignoring initial properties , preventing transition. behind scenes, browsers batch property changes before painting which, while speeding rendering, can have adverse affects. the solution force redraw between applying 2 sets of properties. simple method of doing accessing dom element’s offsetheight property [...] in fact, hack work in current chrome/firefox versions. updated code ( fiddle - click run after opening fiddle run animation again): var el = document.queryselector('div'...
