How to access a class outside of processWire?

[Peter Oehman]

I'm trying to use a class in a file outside of ProcessWire, the classes name is captcha. When trying to access it this is the error message:  Uncaught Error: Class 'ProcessWire\CAPTCHA' not found

I'm guessing this is ProcessWire looking for any classes in the system and not finding any, so how can I access this class?

I should note that this error doesn't occur while requiring the file, but it occurs when I try to make a 'new Captcha'

The error message shows that you are trying to create a new Instance of CAPTCHA but in the ProcessWire namespace. This is because you have something like this at the top of your file:

<?php namespace ProcessWire;

Simply adding a \ should fix this error:

$cap = new \CAPTCHA();

i've a problem mutally in the same area:
coming from drupal where krumo (http://krumo.kaloyan.info/) is part of the widely used development module and an easy way to insert krumo(object/variable/array) at any place to have a handy you have a collapsed view of the input as a great replacement of print_r. i'm frequently using it also in php projects (without namespaces).
i include it in processwire like this:

define('dir', dirname(__FILE__));
include_once(dir.'/includes/krumo/class.krumo.php');
krumo::$skin = 'orange'; // just a theme of krumo

krumo works fine as expected as long as i use e.g. »normal« php arrays.
when i hand over a WireArray, e.g. a page array it stops working with fatal errors, obviously due to krumo being called as class inside of another namespace.
i fiddled around with the $wireArray->getArray() method, but no avail.
how can i globally display the processwire objects the same way as standard php objects?

... or does anyone an alternative method of displaying any kind of data (objects/arrays/variables) for debugging with a page?

Maybe not a solution to your problems, but have you already tried https://processwire.com/modules/tracy-debugger/ ? I think it does what you are looking for and so much more ?

thanks a lot for pointing me to tracy debugger. the d() method is what i'm looking for ?

[bernhard]

Yes, if you want to dump directly (like echo), then d() is what you are looking for. But you can also use bd() to dump everything in the debug bar (bottom right). That's especially handy in ajax calls and such.

bd() is nice as well. thanks for this additional hint! ?
