What is this plugin for? What can you do with it? What's the advantage of calling a named php function? Is this just a different way to make a syntax plug-in, for people who know php but don't want to learn the dokuwiki syntax? – <a href="https://forum.dokuwiki.org/u/Zioth" class="interwiki iw_user" title="https://forum.dokuwiki.org/u/Zioth">Zioth</a> </p> <p> I often want to run php to query a database and output the result. These queries sometimes involve other functionality that would not be handled by the generic database plugins available. I would not want to write a plugin for each type of query I run. Also for security reasons I am reluctant to allow php to be executed on a wiki page. The phpinc plugin was close to providing this functionality but it appears to have some security issues and states that it is no longer supported. With this function plugin I can easily and I believe securely connect a php function to run on a wiki page. If the php functions are general in functionality they could be documented on the wiki for use by the users. </p> <p> I provided a simplified example as the function I am running involves interfacing with a database with specific tables. If I create a function better suited as an example I will provide it. Best regards – <a href="https://forum.dokuwiki.org/u/tom_c" class="interwiki iw_user" title="https://forum.dokuwiki.org/u/tom_c">tom_c</a> </p> <p> I noticed a problem when I was using two different functions on a single page. The run() declaration was already defined when it hit the second function call. I was able to solve this by using variable function declarations. Here is the updated render function in syntax.php and the function declaration in the example helloworld.php </p> <pre class="code syntaxphp"> function render($mode, &$renderer, $indata) { global $conf; if($mode == 'xhtml'){ list($state, $data) = $indata;   switch ($state) { case DOKU_LEXER_SPECIAL : preg_match("#^<function=(.+)>$#", $data, $matches); $func = $matches[1]; $a = explode('?', $func); $func = $a[0]; if (!empty($a[1])) { parse_str($a[1], $params); } else { $params = ''; } if(preg_match("#^[a-z0-9\-_ \./]+$#i", $func)) { $renderer->info['cache'] = FALSE; $filename = DOKU_PLUGIN . 'function/functions/' . $this->getConf($func); include ($filename); $renderer->doc .= $thisfunction($params); } else $renderer->doc .= $renderer->_xmlEntities($data); break;   } return true; }   // unsupported $mode return false; } </pre> <pre class="code helloworldphp">$thisfunction = function($params) { // Create output data $dataout='<p class="cellGreen">Hello World!</p>';   $num=(int)$params['num']; $dataout .= ' The '.($num+1).' parameters were the number '.$num .' preceded by <br />'; foreach ($params AS $key=>$val){ if ($val != $num) $dataout.=$val.'<br />'; } return $dataout; };</pre> <p> Using a variable to hold the function allows it to be overwritten for each function declaration. – <a href="https://forum.dokuwiki.org/u/millsdude" class="interwiki iw_user" title="https://forum.dokuwiki.org/u/millsdude">millsdude</a> </p> <p> Millsdude, thanks for this update! It works real nice. I incorporated it into the release. – <a href="https://forum.dokuwiki.org/u/tom_c" class="interwiki iw_user" title="https://forum.dokuwiki.org/u/tom_c">tom_c</a> </p> <p> It may be worth noting that, although DokuWiki itself <a href="/requirements" class="wikilink1" title="requirements" data-wiki-id="requirements">requires only PHP version 5.2</a>, the function plugin seems to require a more recent version. The plugin makes use of <a href="http://php.net/manual/en/functions.anonymous.php" class="urlextern" title="http://php.net/manual/en/functions.anonymous.php">anonymous function variable assignment</a>, a capability introduced in PHP version 5.3. – <a href="https://forum.dokuwiki.org/u/areeves" class="interwiki iw_user" title="https://forum.dokuwiki.org/u/areeves">areeves</a> </p> </div> <div class="secedit editbutton_section editbutton_8"><form class="button btn_secedit" method="post" action="/plugin:function"><div class="no"><input type="hidden" name="do" value="edit" /><input type="hidden" name="rev" value="1527718586" /><input type="hidden" name="summary" value="[Discussion] " /><input type="hidden" name="target" value="section" /><input type="hidden" name="hid" value="discussion" /><input type="hidden" name="codeblockOffset" value="3" /><input type="hidden" name="range" value="2898-" /><button type="submit" title="Discussion">Edit</button></div></form></div>  </div> <div class="docInfo"><bdi>plugin/function.txt</bdi> · Last modified: <time datetime="2018-05-31T00:16:26+0200">2018-05-31 00:16</time> by <bdi>Klap-in</bdi></div> <hr class="a11y" /> </div></main>  <nav id="dokuwiki__pagetools" aria-labelledby="dokuwiki__pagetools__heading"> <h3 class="a11y" id="dokuwiki__pagetools__heading">Page Tools</h3> <div class="tools"> <ul> <li class="edit"><a href="/plugin:function?do=edit" title="Edit this page [e]" rel="nofollow" accesskey="e"><span>Edit this page</span><svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24"><path d="M20.71 7.04c.39-.39.39-1.04 0-1.41l-2.34-2.34c-.37-.39-1.02-.39-1.41 0l-1.84 1.83 3.75 3.75M3 17.25V21h3.75L17.81 9.93l-3.75-3.75L3 17.25z"/></svg></a></li><li class="revs"><a href="/plugin:function?do=revisions" title="Old revisions [o]" rel="nofollow" accesskey="o"><span>Old revisions</span><svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24"><path d="M11 7v5.11l4.71 2.79.79-1.28-4-2.37V7m0-5C8.97 2 5.91 3.92 4.27 6.77L2 4.5V11h6.5L5.75 8.25C6.96 5.73 9.5 4 12.5 4a7.5 7.5 0 0 1 7.5 7.5 7.5 7.5 0 0 1-7.5 7.5c-3.27 0-6.03-2.09-7.06-5h-2.1c1.1 4.03 4.77 7 9.16 7 5.24 0 9.5-4.25 9.5-9.5A9.5 9.5 0 0 0 12.5 2z"/></svg></a></li><li class="backlink"><a href="/plugin:function?do=backlink" title="Backlinks" rel="nofollow"><span>Backlinks</span><svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24"><path d="M10.59 13.41c.41.39.41 1.03 0 1.42-.39.39-1.03.39-1.42 0a5.003 5.003 0 0 1 0-7.07l3.54-3.54a5.003 5.003 0 0 1 7.07 0 5.003 5.003 0 0 1 0 7.07l-1.49 1.49c.01-.82-.12-1.64-.4-2.42l.47-.48a2.982 2.982 0 0 0 0-4.24 2.982 2.982 0 0 0-4.24 0l-3.53 3.53a2.982 2.982 0 0 0 0 4.24m2.82-4.24c.39-.39 1.03-.39 1.42 0a5.003 5.003 0 0 1 0 7.07l-3.54 3.54a5.003 5.003 0 0 1-7.07 0 5.003 5.003 0 0 1 0-7.07l1.49-1.49c-.01.82.12 1.64.4 2.43l-.47.47a2.982 2.982 0 0 0 0 4.24 2.982 2.982 0 0 0 4.24 0l3.53-3.53a2.982 2.982 0 0 0 0-4.24.973.973 0 0 1 0-1.42z"/></svg></a></li><li class="top"><a href="#dokuwiki__top" title="Back to top [t]" rel="nofollow" accesskey="t"><span>Back to top</span><svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24"><path d="M13 20h-2V8l-5.5 5.5-1.42-1.42L12 4.16l7.92 7.92-1.42 1.42L13 8v12z"/></svg></a></li> </ul> </div> </nav> </div>  <footer id="dokuwiki__footer"><div class="pad"> <div class="license">Except where otherwise noted, content on this wiki is licensed under the following license: <bdi><a href="https://creativecommons.org/licenses/by-sa/4.0/deed.en" rel="license" class="urlextern">CC Attribution-Share Alike 4.0 International</a></bdi></div> <div class="buttons"> <a href="https://creativecommons.org/licenses/by-sa/4.0/deed.en" rel="license"><img src="/lib/images/license/button/cc-by-sa.png" alt="CC Attribution-Share Alike 4.0 International" /></a> <a href="https://www.dokuwiki.org/donate" title="Donate" ><img src="/lib/tpl/dokuwiki/images/button-donate.gif" width="80" height="15" alt="Donate" /></a> <a href="https://php.net" title="Powered by PHP" ><img src="/lib/tpl/dokuwiki/images/button-php.gif" width="80" height="15" alt="Powered by PHP" /></a> <a href="//validator.w3.org/check/referer" title="Valid HTML5" ><img src="/lib/tpl/dokuwiki/images/button-html5.png" width="80" height="15" alt="Valid HTML5" /></a> <a href="//jigsaw.w3.org/css-validator/check/referer?profile=css3" title="Valid CSS" ><img src="/lib/tpl/dokuwiki/images/button-css.png" width="80" height="15" alt="Valid CSS" /></a> <a href="https://dokuwiki.org/" title="Driven by DokuWiki" ><img src="/lib/tpl/dokuwiki/images/button-dw.png" width="80" height="15" alt="Driven by DokuWiki" /></a> </div> <div style="margin-top: 2em;
