  <h3>File upload configuration</h3>
  <p>Enano supports the ability to upload files to your website and store the files in the database. This enables you to embed images
     and such into pages without manually writing the HTML. However, the upload feature can sometimes pose a risk to your site, as viruses
     and executable files can sometimes be uploaded.</p>
  <p><label><input type="checkbox" name="enable_uploads" <?php if(getConfig('enable_uploads')=='1') echo 'checked="checked"'; ?> /> <b>Enable file uploads</b></label></p>
  <p>Maximum file size: <input name="max_file_size" onkeyup="if(!this.value.match(/^([0-9\.]+)$/ig)) this.value = this.value.substr(0,this.value.length-1);" value="<?php echo getConfig('max_file_size'); ?>" /> <select name="fs_units"><option value="1" selected="selected">bytes</option><option value="1024">KB</option><option value="1048576">MB</option></select></p>
  <p>You can allow Enano to generate thumbnails of images automatically. This feature requires ImageMagick to work properly. If your server
     does not have ImageMagick on it, Enano will simply make your users' browsers scale the images. In most cases this is fine, but if you
     are uploading large (>100KB) images and embedding them inside of pages, you should try to enable ImageMagick because transferring these
     large images many times can cost you quite a lot of bandwidth.</p>
  <p><label><input type="checkbox" name="enable_imagemagick" <?php if(getConfig('enable_imagemagick')=='1') echo 'checked="checked"'; ?> /> Use ImageMagick to scale images</label><br />
     Path to ImageMagick: <input type="text" name="imagemagick_path" value="<?php if(getConfig('imagemagick_path')) echo getConfig('imagemagick_path'); else echo '/usr/bin/convert'; ?>" /><br />
     On Linux and Unix servers, the most likely options here are /usr/bin/convert and /usr/local/bin/convert. If you server runs Windows, then
     ImageMagick is most likely to be C:\Windows\Convert.exe or C:\Windows\System32\Convert.exe.
     </p>
  <p>If you use ImageMagick to scale images, your server will be very busy constantly scaling images if your website is busy, and your site
     may experience slowdowns. You can dramatically speed up this scaling process if you use a directory to cache thumbnail images.</p>
  <p><b>Please note:</b> the cache/ directory on your server <u>must</u> be writable by the server. While this is not usually a problem on
     Windows servers, most Linux/Unix servers will require you to CHMOD the cache/ directory to 777. See your FTP client's user guide for
     more information on how to do this.<?php if(!is_writable(ENANO_ROOT.'/cache/')) echo ' <b>At present, it seems that the cache directory
     is not writable. The checkbox below has been disabled to maintain the stability of Enano.</b>'; ?></p>
  <p><label><input type="checkbox" name="cache_thumbs" <?php if(getConfig('cache_thumbs')=='1' && is_writable(ENANO_ROOT.'/cache/')) echo 'checked="checked"'; elseif(!is_writable(ENANO_ROOT.'/cache/')) echo 'readonly="readonly"'; ?> /> Cache thumbnailed images</label></p>
  <p>Lastly, you can choose whether file history will be saved. If this option is turned on, you will be able to roll back any malicious
     changes made to uploaded files, but this requires a significant amount of database storage. You should probably leave this option
     enabled unless you have less than 250MB of MySQL database space.</p>
  <p><label><input type="checkbox" name="file_history" <?php if(getConfig('file_history')=='1') echo 'checked="checked"'; ?> /> Keep a history of uploaded files</label></p>
  <hr style="margin-left: 1em;" />

  <h2>Editing and managing the Enano sidebar</h2>
   <p>The Enano sidebar is a versatile tool when scripted correctly. You don't have to be a programmer to enjoy the features the Sidebar
      provides; however, editing the sidebar requires a small bit of programming knowledge and an understanding of Enano's system message
      markup language.
      </p>
   <p>The Enano system markup language is somewhat similar to HTML, in that it uses tags (&lt;example&gt;like this&lt;/example&gt;) for the
      main syntax. However, Enano uses curly brackets ({ and }) as opposed to less-than and greater-than signs (&lt; and &gt;).</p>
   <p>Programming the Enano sidebar requires the use of two tags: {slider} and {if}. The {slider} tag is used to create a new heading
      on the sidebar, and all text enclosed in that tag will be collapsed when the heading is clicked. To specify the text on the heading,
      use an equals sign (=) after the "slider" text. Then insert any links (they should be wiki-formatted) to internal Enano pages and
      external sites.</p>
   <p>So here is what the language for the default sidebar's "Navigation" heading looks like:</p>
   <pre>{slider=Navigation}
  [[Main Page|Home]]
  [[Enano:Sidebar|Edit the sidebar]]
{/slider}</pre>
   <p>Pretty simple, huh? Good, now we're going to learn another common aspect of Enano programming: conditionals. The {if} tag allows you
      to decide whether a portion of the sidebar will be displayed based on a template variable. Currently the only available conditions are
      "user_logged_in" and "auth_admin", but more will be added soon. To use a conditional, enter {if conditional_name}, and then the
      wiki-formatted text that you want to be under that condition, and then close the tag with {/if}. In the same way, you can reverse the
      effect with {!if}. With {!if}, the closing tag is still {/if}, so keep that in mind. An {else} tag will be supported soon.</p>
   <p>Now it's time for some real fun: variables. All template variables can be accessed from the sidebar. A variable is simply the
      variable name, prefixed by a dollar sign ($). Some of the most common variables are $USERNAME, $SITE_NAME, $SITE_DESC, and $PAGE_NAME.
      The sidebar also has some special variables that it uses for some of its links. The logout link can be added with $LOGOUT_LINK, and
      the "change theme" button can be added with $STYLE_LINK.</p>
   <p>So here is the Enano markup for the portion of the sidebar that contains the user tools:</p>
   <pre>{slider=$USERNAME}
  [[User:$USERNAME|User page]]
  [[Special:Contributions?user=$USERNAME|My Contributions]]
  {if user_logged_in}
    [[Special:Preferences|Preferences]]
    $THEME_LINK
  {/if}
  {if auth_admin}
    [[Special:Administration|Administration]]
  {/if}
  {if user_logged_in}
    $LOGOUT_LINK
  {/if}
  {!if user_logged_in}
    Create an account
    Log in
  {/if}
{/slider}</pre>

                ALWAYS remember to write secure code! The Enano team is not responsible if someone drops all your tables because of an SQL injection vulnerability in your sidebar code. You are probably better off using the template-formatted block type.

              <p>
                <span style="color: red;">
                  It is especially important to note that this code is NOT checked for errors! If there is a syntax error in your code here, it will prevent any pages from loading AT ALL. So you need to use an external PHP editor (like <a href="http://www.jedit.org">jEdit</a>) to check your syntax before you hit save.
                </span> You have been warned.
              </p>
              <p>
                Also, you should avoid using output buffering functions (ob_[start|end|get_contents|clean]) here, because Enano uses those to track output from this script.

                The standard &lt;?php and ?&gt; tags work here. Don't use an initial "&lt;?php" or it will cause a parse error.
