320<h3 id="what-can-i-do-with-plugins">What can I do with plugins?</h3>
321<p>The plugin system let you:</p>
322<ul>
323<li>insert content into specific places across templates.</li>
324<li>alter data before templates rendering.</li>
325<li>alter data before saving new links.</li>
326</ul>
327<h3 id="how-can-i-create-a-plugin-for-shaarli">How can I create a plugin for Shaarli?</h3>
328<p>First, chose a plugin name, such as <code>demo_plugin</code>.</p>
329<p>Under <code>plugin</code> folder, create a folder named with your plugin name. Then create a <plugin_name>.php file in that folder.</p>
330<p>You should have the following tree view:</p>
331<pre><code>| index.php
332| plugins/
333|---| demo_plugin/
334| |---| demo_plugin.php
335</code></pre>
336
337<h3 id="plugin-initialization">Plugin initialization</h3>
338<p>At the beginning of Shaarli execution, all enabled plugins are loaded. At this point, the plugin system looks for an <code>init()</code> function to execute and run it if it exists. This function must be named this way, and takes the <code>ConfigManager</code> as parameter.</p>
339<pre><code>&lt;plugin_name&gt;_init($conf)
340</code></pre>
341<p>This function can be used to create initial data, load default settings, etc. But also to set <em>plugin errors</em>. If the initialization function returns an array of strings, they will be understand as errors, and displayed in the header to logged in users.</p>
342<h3 id="understanding-hooks">Understanding hooks</h3>
343<p>A plugin is a set of functions. Each function will be triggered by the plugin system at certain point in Shaarli execution.</p>
344<p>These functions need to be named with this pattern:</p>
345<pre><code>hook_&lt;plugin_name&gt;_&lt;hook_name&gt;($data, $conf)
346</code></pre>
347
348<p>Parameters:</p>
349<ul>
350<li>data: see <a href="https://github.com/shaarli/Shaarli/wiki/Plugin-System#plugins-data">$data section</a></li>
351<li>conf: the <code>ConfigManager</code> instance.</li>
352</ul>
353<p>For exemple, if my plugin want to add data to the header, this function is needed:</p>
354<pre><code>hook_demo_plugin_render_header
355</code></pre>
356<p>If this function is declared, and the plugin enabled, it will be called every time Shaarli is rendering the header.</p>
357<h3 id="plugins-data">Plugin's data</h3>
358<h4 id="parameters">Parameters</h4>
359<p>Every hook function has a <code>$data</code> parameter. Its content differs for each hooks.</p>
360<p><strong>This parameter needs to be returned every time</strong>, otherwise data is lost.</p>
361<pre><code>return $data;
362</code></pre>
363<h4 id="filling-templates-placeholder">Filling templates placeholder</h4>
364<p>Template placeholders are displayed in template in specific places.</p>
365<p>RainTPL displays every element contained in the placeholder's array. These element can be added by plugins.</p>
366<p>For example, let's add a value in the placeholder <code>top_placeholder</code> which is displayed at the top of my page:</p>
367<pre><code class="php">$data['top_placeholder'][] = 'My content';
368# OR
369array_push($data['top_placeholder'], 'My', 'content');
370
371return $data;
372</code></pre>
373
374<h4 id="data-manipulation">Data manipulation</h4>
375<p>When a page is displayed, every variable send to the template engine is passed to plugins before that in <code>$data</code>.</p>
376<p>The data contained by this array can be altered before template rendering.</p>
377<p>For exemple, in linklist, it is possible to alter every title:</p>
378<pre><code class="php">// mind the reference if you want $data to be altered
379foreach ($data['links'] as &amp;$value) {
380 // String reverse every title.
381 $value['title'] = strrev($value['title']);
382}
383
384return $data;
385</code></pre>
386
387<h3 id="metadata">Metadata</h3>
388<p>Every plugin needs a <code>&lt;plugin_name&gt;.meta</code> file, which is in fact an <code>.ini</code> file (<code>KEY="VALUE"</code>), to be listed in plugin administration.</p>
389<p>Each file contain two keys:</p>
390<ul>
391<li><code>description</code>: plugin description</li>
392<li><code>parameters</code>: user parameter names, separated by a <code>;</code>.</li>
393<li><code>parameter.&lt;PARAMETER_NAME&gt;</code>: add a text description the specified parameter.</li>
394</ul>
395<blockquote>
396<p>Note: In PHP, <code>parse_ini_file()</code> seems to want strings to be between by quotes <code>"</code> in the ini file.</p>
397</blockquote>
398<h3 id="its-not-working">It's not working!</h3>
399<p>Use <code>demo_plugin</code> as a functional example. It covers most of the plugin system features.</p>
400<p>If it's still not working, please <a href="https://github.com/shaarli/Shaarli/issues/new">open an issue</a>.</p>

733<h3 id="plugin-administration">Plugin administration</h3>
734<p>Your theme must include a plugin administration page: <code>pluginsadmin.html</code>.</p>
735<blockquote>
736<p>Note: repo's template link needs to be added when the PR is merged.</p>
737</blockquote>
738<p>Use the default one as an example.</p>
739<p>Aside from classic RainTPL loops, plugins order is handle by JavaScript. You can just include <code>plugin_admin.js</code>, only if:</p>
740<ul>
741<li>you're using a table.</li>
742<li>you call orderUp() and orderUp() onclick on arrows.</li>
743<li>you add data-line and data-order to your rows.</li>
744</ul>
745<p>Otherwise, you can use your own JS as long as this field is send by the form:</p>
746<p><input type="hidden" name="order_{$key}" value="{$counter}"></p>
747<h3 id="placeholder-system">Placeholder system</h3>
748<p>In order to make plugins work with every custom themes, you need to add variable placeholder in your templates. </p>
749<p>It's a RainTPL loop like this:</p>
750<pre><code>{loop="$plugin_variable"}
751 {$value}
752{/loop}
753</code></pre>
754<p>You should enable <code>demo_plugin</code> for testing purpose, since it uses every placeholder available.</p>
