\section{How to use horde shares in your custom application}
\textit{work in progress}

Let's assume you followed the  <a href="https://wiki.horde.org/CreatingYourFirstModule">Creating your first module</a> guide as far as it applies to horde4 and created a new horde app called "hort". Hort is an old German word for treasure as well as the place where the treasure is kept. Hort should keep safes which hold user/password pairs or other secret credentials. Those safes should be shareable among users. This is where horde\_shares comes into play.

\subsection{basic setup in Application.php \_init()}
We want to add an injector for the shares API whenever the app is initialized and we want to auto-create an initial "home" share for users which do not yet own one.

<pre><code class="language-php">
    protected function \_init()
    \{
        // Create a share instance.
        \$GLOBALS['hort\_shares'] = \$GLOBALS['injector']->getInstance('Horde\_Core\_Factory\_Share')->create();

        /* If the user doesn't own a safe, create one. */
        if (!empty(\$GLOBALS['conf']['share']['auto\_create']) \&\&
            \$GLOBALS['registry']->getAuth() \&\&
            !\$GLOBALS['hort\_shares']->countShares(\$GLOBALS['registry']->getAuth())) \{
            \$identity = \$GLOBALS['injector']->getInstance('Horde\_Core\_Factory\_Identity')->create();
            \$share = \$GLOBALS['hort\_shares']->newShare(
                \$GLOBALS['registry']->getAuth(),
                strval(new Horde\_Support\_Randomid()),
                sprintf(\_("Default safe of \%s"), \$identity->getName())
            );
            \$GLOBALS['hort\_shares']->addShare(\$share);
        \}

    \}
</code></pre>
\subsection{List of safes in Application.php menu()}
Next we want to add a page with a list of safes (shares) in the menu.<br />
Go to the menu() function in Application.php

<pre><code class="language-php">
        \$menu->add(Horde::url('safes.php'), \_("Password Safes"), 'user.png');
</code></pre>
\subsection{migrations script (database setup) for shares and sharesng driver tables}
Create a directory hort/migrations/ with a file 1\_hort\_tables.php

<pre><code class="language-php">
class HortBaseTables extends Horde\_Db\_Migration\_Base

    /**

    public function up()
