  106. <h3 id="what-can-i-do-with-plugins">What can I do with plugins?</h3>
    107. 

  107. <p>The plugin system let you:</p>
    108. 

  108. <ul>
    109. 

  109. <li>insert content into specific places across templates.</li>
    110. 

  110. <li>alter data before templates rendering.</li>
    111. 

  111. <li>alter data before saving new links.</li>
    112. 

  112. </ul>
    113. 

  113. <h3 id="how-can-i-create-a-plugin-for-shaarli">How can I create a plugin for Shaarli?</h3>
    114. 

  114. <p>First, chose a plugin name, such as <code>demo_plugin</code>.</p>
    115. 

  115. <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>
    116. 

  116. <p>You should have the following tree view:</p>
    117. 

  117. <pre><code>| index.php
    118. 

  118. | plugins/
    119. 

  119. |---| demo_plugin/
    120. 

  120. |   |---| demo_plugin.php</code></pre>
    121. 

  121. <h3 id="understanding-hooks">Understanding hooks</h3>
    122. 

  122. <p>A plugin is a set of functions. Each function will be triggered by the plugin system at certain point in Shaarli execution.</p>
    123. 

  123. <p>These functions need to be named with this pattern:</p>
    124. 

  124. <pre><code>hook_&lt;plugin_name&gt;_&lt;hook_name&gt;</code></pre>
    125. 

  125. <p>For exemple, if my plugin want to add data to the header, this function is needed:</p>
    126. 

  126. <pre><code>hook_demo_plugin_render_header()</code></pre>
    127. 

  127. <p>If this function is declared, and the plugin enabled, it will be called every time Shaarli is rendering the header.</p>
    128. 

  128. <h3 id="plugins-data">Plugin's data</h3>
    129. 

  129. <h4 id="parameters">Parameters</h4>
    130. 

  130. <p>Every hook function has a <code>$data</code> parameter. Its content differs for each hooks.</p>
    131. 

  131. <p><strong>This parameter needs to be returned every time</strong>, otherwise data is lost.</p>
    132. 

  132. <pre><code>return $data;</code></pre>
    133. 

  133. <h4 id="filling-templates-placeholder">Filling templates placeholder</h4>
    134. 

  134. <p>Template placeholders are displayed in template in specific places.</p>
    135. 

  135. <p>RainTPL displays every element contained in the placeholder's array. These element can be added by plugins.</p>
    136. 

  136. <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>
    137. 

  137. <pre class="sourceCode php"><code class="sourceCode php"><span class="kw">$data</span><span class="ot">[</span><span class="st">&#39;top_placeholder&#39;</span><span class="ot">[]</span> = <span class="st">&#39;My content&#39;</span><span class="ot">;](]</span>-=-<span class="st">&#39;My-content&#39;</span><span class="ot">;</span>.html<span class="ot">)</span>
    138. 

  138. <span class="co"># OR</span>
    139. 

  139. <span class="fu">array_push</span><span class="ot">(</span><span class="kw">$data</span><span class="ot">[</span><span class="st">&#39;top_placeholder&#39;</span><span class="ot">],</span> <span class="st">&#39;My&#39;</span><span class="ot">,</span> <span class="st">&#39;content&#39;</span><span class="ot">);[](</span>.html<span class="ot">)</span>
    140. 

  140. 

  141. <span class="kw">return</span> <span class="kw">$data</span><span class="ot">;</span></code></pre>
    142. 

  142. <h4 id="data-manipulation">Data manipulation</h4>
    143. 

  143. <p>When a page is displayed, every variable send to the template engine is passed to plugins before that in <code>$data</code>.</p>
    144. 

  144. <p>The data contained by this array can be altered before template rendering.</p>
    145. 

  145. <p>For exemple, in linklist, it is possible to alter every title:</p>
    146. 

  146. <pre class="sourceCode php"><code class="sourceCode php"><span class="co">// mind the reference if you want $data to be altered</span>
    147. 

  147. <span class="kw">foreach</span> <span class="ot">(</span><span class="kw">$data</span><span class="ot">[</span><span class="st">&#39;links&#39;</span><span class="ot">]</span> <span class="kw">as</span> &amp;<span class="kw">$value</span><span class="ot">)</span> {<span class="ot">[](</span>.html<span class="ot">)</span>
    148. 

  148.     <span class="co">// String reverse every title.</span>
    149. 

  149.     <span class="kw">$value</span><span class="ot">[</span><span class="st">&#39;title&#39;</span><span class="ot">]</span> = <span class="fu">strrev</span><span class="ot">(</span><span class="kw">$value</span><span class="ot">[</span><span class="st">&#39;title&#39;</span><span class="ot">]);[](</span>.html<span class="ot">)</span>
    150. 

  150. }
    151. 

  151. 

  152. <span class="kw">return</span> <span class="kw">$data</span><span class="ot">;</span></code></pre>
    153. 

  153. <h3 id="its-not-working">It's not working!</h3>
    154. 

  154. <p>Use <code>demo_plugin</code> as a functional example. It covers most of the plugin system features.</p>
    155.
