cakePHP get a variable from each Model and Controller -


i got question. have db table settings (id, name). if read them db

$settings = $this->setting->find('list');

how can in appcontroller or access each controller , model?

hope can me.

thanks

explanation:

i assume you're looking below (obviously you'll want tweak per own application, - it's idea).

in app controller, it

  • finds settings table
  • repeats through each , puts each 1 "configure" variable

code:

/**  * read settings db , populate them in constants  */ function fetchsettings(){     $this->loadmodel('setting');     $settings = $this->setting->findall();      foreach($settings $settingsdata) {         $value = $settingsdata['setting']['default_value'];          //note: can't check !empty because values 0 (zero)         if(isset($settingsdata['setting']['value'])              && $settingsdata['setting']['value'] !== null             && $settingsdata['setting']['value'] !== '') {             $value = $settingsdata['setting']['value'];         }         configure::write($settingsdata['setting']['key'], $value);    } }

then, can access them anywhere in app via configure::read('myvar');

a warning cakephp book configure variables. (i think they're fine use in case, - keep in mind):

cakephp’s configure class can used store , retrieve application or runtime specific values. careful, class allows store in it, use in other part of code: sure temptation break mvc pattern cakephp designed for. main goal of configure class keep centralized variables can shared between many objects. remember try live “convention on configuration” , won’t end breaking mvc structure we’ve set in place.

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).
