< h2 id = "developer-api" > Developer API< / h2 >
< h3 id = "what-can-i-do-with-plugins" > What can I do with plugins?< / h3 >
< p > The plugin system let you:< / p >
< ul >
< li > insert content into specific places across templates.< / li >
< li > alter data before templates rendering.< / li >
< li > alter data before saving new links.< / li >
< / ul >
< h3 id = "how-can-i-create-a-plugin-for-shaarli" > How can I create a plugin for Shaarli?< / h3 >
< p > First, chose a plugin name, such as < code > demo_plugin< / code > .< / p >
< 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 >
< p > You should have the following tree view:< / p >
< pre > < code > | index.php
| plugins/
|---| demo_plugin/
| |---| demo_plugin.php
< / code > < / pre >
< h3 id = "plugin-initialization" > Plugin initialization< / h3 >
< 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 >
< pre > < code > < plugin_name> _init($conf)
< / code > < / pre >
< p > This function can be used to create initial data, load default settings, etc. But also to set < em > plugin errors< / em > . If the initialization function returns an array of strings, they will be understand as errors, and displayed in the header to logged in users.< / p >
< h3 id = "understanding-hooks" > Understanding hooks< / h3 >
< p > A plugin is a set of functions. Each function will be triggered by the plugin system at certain point in Shaarli execution.< / p >
< p > These functions need to be named with this pattern:< / p >
< pre > < code > hook_< plugin_name> _< hook_name> ($data, $conf)
< / code > < / pre >
< p > Parameters:< / p >
< ul >
< li > data: see < a href = "https://github.com/shaarli/Shaarli/wiki/Plugin-System#plugins-data" > $data section< / a > < / li >
< li > conf: the < code > ConfigManager< / code > instance.< / li >
< / ul >
< p > For exemple, if my plugin want to add data to the header, this function is needed:< / p >
< pre > < code > hook_demo_plugin_render_header
< / code > < / pre >
< p > If this function is declared, and the plugin enabled, it will be called every time Shaarli is rendering the header.< / p >
< h3 id = "plugins-data" > Plugin's data< / h3 >
< h4 id = "parameters" > Parameters< / h4 >
< p > Every hook function has a < code > $data< / code > parameter. Its content differs for each hooks.< / p >
< p > < strong > This parameter needs to be returned every time< / strong > , otherwise data is lost.< / p >
< pre > < code > return $data;
< / code > < / pre >
< h4 id = "filling-templates-placeholder" > Filling templates placeholder< / h4 >
< p > Template placeholders are displayed in template in specific places.< / p >
< p > RainTPL displays every element contained in the placeholder's array. These element can be added by plugins.< / p >
< 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 >
< pre > < code class = "php" > $data['top_placeholder'][] = 'My content';
# OR
array_push($data['top_placeholder'], 'My', 'content');
return $data;
< / code > < / pre >
< h4 id = "data-manipulation" > Data manipulation< / h4 >
< p > When a page is displayed, every variable send to the template engine is passed to plugins before that in < code > $data< / code > .< / p >
< p > The data contained by this array can be altered before template rendering.< / p >
< p > For exemple, in linklist, it is possible to alter every title:< / p >
< pre > < code class = "php" > // mind the reference if you want $data to be altered
foreach ($data['links'] as & $value) {
// String reverse every title.
$value['title'] = strrev($value['title']);
}
return $data;
< / code > < / pre >
< h3 id = "metadata" > Metadata< / h3 >
< p > Every plugin needs a < code > < plugin_name> .meta< / code > file, which is in fact an < code > .ini< / code > file (< code > KEY="VALUE"< / code > ), to be listed in plugin administration.< / p >
< p > Each file contain two keys:< / p >
< ul >
< li > < code > description< / code > : plugin description< / li >
< li > < code > parameters< / code > : user parameter names, separated by a < code > ;< / code > .< / li >
< li > < code > parameter.< PARAMETER_NAME> < / code > : add a text description the specified parameter.< / li >
< / ul >
< blockquote >
< 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 >
< / blockquote >
< h3 id = "its-not-working" > It's not working!< / h3 >
< p > Use < code > demo_plugin< / code > as a functional example. It covers most of the plugin system features.< / p >
