[fw-general] Calling externa l autoload function – how to?

[bytte]

I'm using DOMPDF in a project of mine and I was wondering how I can call
DOMPDF's autoload function so it can function together with the one from
Zend Framework.

Here's what DOMPDF says:

/**
 * DOMPDF autoload function
 *
 * If you have an existing autoload function, add a call to this function
 * from your existing __autoload() implementation.
 *
 * @param string $class
 */
function DOMPDF_autoload($class) {
  $filename = mb_strtolower($class) . .cls.php;
  require_once(DOMPDF_INC_DIR . /$filename);
}

How exactly can I make it work together with the ZF?

Use spl_autoload_register() to register that function with the SPL
autoloader:

spl_autoload_register('DOMPDF_autoload');

and then call:

Zend_Loader::registerAutoload();

Starting in ZF 1.8, you can do the following instead:

require_once 'Zend/Loader/Autoloader.php';
$autoloader = Zend_Loader_Autoloader::getInstance();
$autoloader-pushAutoloader('DOMPDF_autoload');

 Thanks. But I'm confused. Early on in my bootstrap I have this code:
 
 set_include_path('.' . PATH_SEPARATOR . '../library/'
 . PATH_SEPARATOR . '../application/models'
 . PATH_SEPARATOR . '../application/forms'
 . PATH_SEPARATOR . '../library/dompdf-0.5.1'
 . PATH_SEPARATOR . get_include_path());
 include Zend/Loader.php;
 Zend_Loader::registerAutoload();
 
 Then where exactly do I need to insert this spl_autoload_register()
 function?

Before the Zend_Loader::registerAutoload() call.

 If I do it in my controller where I create the pdf, the pdf gets created but
 it starts with a lot of warnings because a lot of files in the DOMPDF file
 structure weren't found. Such as:
 
 Warning: Zend_Loader::include_once() [function.include]: Failed opening
 'Style.php' for inclusion
 (include_path='.:../library/:../application/models:../application/forms:../library/dompdf-0.5.1:.:/opt/local/lib/php')
 in /Users/xxx/Sites/zf-test/library/Zend/Loader.php on line 83
 
 If I do it in my bootstrap just before Zend_Loader::registerAutoload(), all
 my other code doesn't work anymore as it looks like the DOMPDF autoloader is
 used to load all the ZF classes. Here's the warnings I get then:
 
 Warning:
 require_once(/Users/xxx/Sites/zf-test/library/dompdf-0.5.1/include/zend_config_ini.cls.php)
 [function.require-once]: failed to open stream: No such file or directory in
 /Users/xxx/Sites/zf-test/library/dompdf-0.5.1/dompdf_config.inc.php on line
 194
 
 Could you provide me with some more information? It would be really helpful.

  Make sure that loader is registered late in the stack because it does a
  require_once, meaning it will throw a fatal if it fails and will prevent
  the
  other autoloaders from trying to load the class.

 But then I get these errors everywhere:

 What am I doing wrong?

Well, *you* aren't -- the authors of DOMPDF are by using require_once in
their autoloader (that's a no-no; autoloaders should be chainable, and
thus fail gracefully). Create your own autoloader function for their
stuff that's a bit less restrictive. For example, try the following in
your bootstrap:

function My_DOMPDF_Autoload($class)
{
$filename = DOMPDF_INC_DIR . '/' . mb_strtolower($class) . '.cls.php';
if (Zend_Loader::isReadable($filename)) {
return include_once $filename;
}
return false;
}

require_once 'Zend/Loader.php';
spl_register_autoload('My_DOMPDF_Autoload');
Zend_Loader::registerAutoload();

and that should work.
