Following the "Creating a simple package" tutorial error

Finanztip · Jul 7th 2020

Hello,

I am following the short tutorial "Creating a simple package" trying to understand how to create a package. Following the instructions the package is created and installed into Woltlab Suite. But when I try to reach url like "http://localhost:9999/wsc/index.php?test/&greet=You" I am receiving error like

I can see that RequestHandler.class.php -> handle() function is receiving $application parameter as "wbb", which means the initial request starts from "app/index.php" file. Is that on purpose?

Are there any other places where I can observe some package related tutorials? Please advise?

Hello,

Could it be that your directory name is simply misleading? The path suggest that the core installed in /wsc/, but this is actually the forum app. How does the configuration look like in "Configuration > Packages > Manage Apps"? Also, please don't change the path configuration there, it will not physically move anything.

Hi,

just checked the paths, I think everything is correct.

**Alexander Ebert** · Jul 8th 2020

These paths do not match the URL of the error message, it reads / and /wcf/ on your screenshot, but the error message refers to the path /wsc/.

Finanztip · Jul 8th 2020

Well that it is according to the official tutorial. There is no "wsc" folder in the file structure.

Trying to reach http://localhost:9999/wcf/index.php?test/&greet=You gives the same error.

How does your class file looks like and is it placed in the correct directory after you installed the plugin?

Finanztip · Jul 8th 2020

The class is placed in "app/wcf/files/lib/page/TestPage.class.php" after plugin installation and it looks exactly the same as per tutorial.

Bellow are changed files

PHP

<?php
namespace wcf\page;
use wcf\system\WCF;

/**
 * A simple test page for demonstration purposes.
 *
 * @author  YOUR NAME
 * @license GNU Lesser General Public License <http://opensource.org/licenses/lgpl-license.php>
 */
class TestPage extends AbstractPage {
  /**
   * @var string
   */
  protected $greet = '';

  /**
   * @inheritDoc
   */
  public function readParameters() {
    parent::readParameters();

    if (isset($_GET['greet'])) $this->greet = $_GET['greet'];
  }

  /**
   * @inheritDoc
   */
  public function readData() {
    parent::readData();

    if (empty($this->greet)) {
      $this->greet = 'World';
    }
  }

  /**
   * @inheritDoc
   */
  public function assignVariables() {
    parent::assignVariables();

    WCF::getTPL()->assign([
      'greet' => $this->greet
    ]);
  }
}

You have to ensure that the TestPage.class.php file is in the same directory as the AbstractPage.class.php file*.

Your path includes files/ which hints at you creating the files archive the wrong way. It must contain the lib/ directory directly and not as a child of a files/ directory!

* This only applies to controllers for Core, App controllers would be placed in app-specific directories, but this is not relevant here.
