CodeIgniter Include - Unable to complete this request due to an error.

Hey guys,

I want to manage some contens for a site running on CodeIgniter using PW.

But as I try to access CI, I get this error: Unable to complete this request due to an error.

I tried these ones, both return that error.

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

require __DIR__.'/../../cms/index.php';

class Processwire extends CI_Controller {

	public function index()
	{
		echo '<pre>';
		
		var_dump($wire->pages->get('/news/'));
	}

}

/* End of file suche.php */
/* Location: ./system/application/controllers/processwire.php */

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Processwire extends CI_Controller {

	private $wire = null;

	function __construct()
	{
		require __DIR__.'/../../cms/index.php';
		$this->wire = $wire;
	}

	public function index()
	{
		echo '<pre>';
		
		var_dump($this->wire->pages->get('/news/'));
	}

}

/* End of file suche.php */
/* Location: ./system/application/controllers/processwire.php */

Any Ideas what might cause the error? PW doesn't log anything, even with debug turned on.

It it CI specific, as I can use the same code using a independent php file.

Thanks

Hi FvG

I think this is an issue with variable scope. One easy way to resolve this is to just use the wire() function, instead of the variable. In your first example, it would just change to:

var_dump( wire('pages')->get('/news/') );
 

That should then work as expected.

It will even happen when I just require it. Required it somewhere else now and got this error:

Error:  Cannot use object of type Config as array (line 36 of /var/www/virtual/fvg/html/system/modules/fuel/config/fuel.php)

One of the issues I didn't notice before was that your controller was called "Processwire" - the CI class name conflicts with ProcessWire's - so I would advise using an alternative name for your CI class. I also think the include path is throwing things out a bit. My test looks something like this:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

require_once(realpath(FCPATH . '../../test/processwire') . '/index.php');

class Welcome extends CI_Controller {

	public function index()
	{
		$this->load->view('welcome_message');
		echo wire('pages')->get('/')->title;
	}
}

/* End of file welcome.php */
/* Location: ./application/controllers/welcome.php */

Can you make changes to yours to reflect the above?

FCPATH is the location of CI's index.php; and realpath() will convert the whole "relative" path to the correct full filesystem path, and then we just add PW's index.php on the end of that.

Yes it sounds to me like there are class name collisions. That won't be an issue once both PW and Fuel are namespaced, but that also doesn't guarantee that the two will run alongside each other either. I do know of people that have used CI and ProcessWire alongside each other, and apparently that works pretty well. But I'm not aware of anyone running ProcessWire and another CMS running on the same request, including files from one another. Though I did once bootstrap Drupal from ProcessWire. :)

      Hello There, I have saw a post that was covering event-calendar with php, ajax and js. That was showing a monthly overview when I click on a "month" button or when I switch the month. And show the events on one particular date when I pick a day. Also, most events are kind of exhibitions and so they have a start date and an end date much later, and occur on each day in-between as well. So on the template I put two date picking fileds date_start and date_end. Is there an elegant way to select the events using the API? If yes, kindly help me out.
      Thanks in Advance

      I am working on my first Process Module. I am creating forms. Fairly straightforward. However, I really can't work out how to create multiple fieldsets?
      $fieldset = $this->modules->get('InputfieldFieldset'); $fieldset->label = 'Customer Source'; $field = $this->modules->get('InputfieldPage'); $field->inputfield = 'InputfieldSelect'; $field->findPagesSelector = 'parent_id=1449, include=hidden'; $field->labelFieldName = 'yff-lead'; $field->name = 'yfflead'; $field->columnWidth = 16; $fieldset->add($field); $field = $this->modules->get('InputfieldPage'); $field->inputfield = 'InputfieldSelect'; $field->findPagesSelector = 'parent_id=1452, include=hidden'; $field->labelFieldName = 'customer-type'; $field->name = 'customertype'; $field->columnWidth = 16; $fieldset->add($field); //Rinse and Repeat $fieldset->label = 'Contacts'; $field = $this->modules->get('InputfieldPage'); $field->inputfield = 'InputfieldSelect'; $field->findPagesSelector = 'parent_id=1538, include=hidden'; $field->labelFieldName = 'salutation'; $field->name = 'salutation'; $field->columnWidth = 16; $fieldset->add($field); I can create the first fieldset (Customer Source) but then get into trouble as the second fieldset overwrites the first. I understand why, but trying to use the open and close fieldset routine has flummoxed me. Any help appreciated.

      Hello forum, we're trying to use Processwire as our REST-API. We are having problems with our API login to Processwire from frontend. It gives us 403 error.
      We have installed ProcessWire to subdirectory (/api/*) and our frontend is static JS files at root ( / ). Apache access logs gives 404 to our POST-request, but browser devtools shows 403 for our POST /api/login request. 
      Processwire backend panel works. We also have a GET endpoint for the API that returns 200 with correct payload.  So we're wondering why does our GET works but POST doesn't?
      Does this have something to do with Processwire .htaccess, or is this because of our webhost? What should we check first? Any help would be appreciated.

      Hi,
      is there a hook after the current (active) page got created? Or which method got called in the Page class after the Constructor of the current page got initialized?
      Thanks.

      I am very sorry for asking this but i totally do not understand how to set values of checbox using API. 
      I have checbox field on my page with name "order_status".
