<title>Naming Conventions</title>
<para>
Plugin files and functions must follow a very specific naming
convention in order to be located by Smarty.
</para>
<para>
The plugin files must be named as follows:
<blockquote>
<para>
<filename>
<replaceable>type</replaceable>.<replaceable>name</replaceable>.php
</filename>
</para>
</blockquote>
</para>
<para>
Where <literal>type</literal> is one of these plugin types:
<itemizedlist spacing="compact">
<listitem><simpara>function</simpara></listitem>
<listitem><simpara>modifier</simpara></listitem>
<listitem><simpara>block</simpara></listitem>
<listitem><simpara>compiler</simpara></listitem>
<listitem><simpara>prefilter</simpara></listitem>
<listitem><simpara>postfilter</simpara></listitem>
<listitem><simpara>outputfilter</simpara></listitem>
<listitem><simpara>resource</simpara></listitem>
<listitem><simpara>insert</simpara></listitem>
</itemizedlist>
</para>
<para>
And <literal>name</literal> should be a valid identifier (letters,
numbers, and underscores only).
</para>
<para>
Some examples: <literal>function.html_select_date.php</literal>,
<literal>resource.db.php</literal>,
<literal>modifier.spacify.php</literal>.
</para>
<para>
The plugin functions inside the plugin files must be named as follows:
<blockquote>
<para>
<function>smarty_<replaceable>type</replaceable>_<replaceable>name</replaceable></function>
</para>
</blockquote>
</para>
<para>
The meanings of <literal>type</literal> and <literal>name</literal> are
the same as before.
</para>
<para>
Smarty will output appropriate error messages if the plugin file it
needs is not found, or if the file or the plugin function are named
improperly.
</para>
