<h1>Module HowTo - Defining required extensions<br>
</h1>
<div style="text-align: left;"><br>
Your account module might require special PHP extensions. LAM can check
this for you and display an error message at the login page.<br>
<br>
</div>
<div style="text-align: left;">You will need to implement the function <span
style="font-weight: bold;">getRequiredExtensions()</span> or use <span
style="font-weight: bold;">meta['extensions']</span>.<br>
<br>
<span style="font-weight: bold; text-decoration: underline;">Example:</span><br
style="font-weight: bold; text-decoration: underline;">
<br>
The <span style="font-style: italic;">posixAccount</span> module needs
to generate password hashes. Therefore it needs the Hash extension.<br>
<br>
<table style="width: 100%; text-align: left;" class="mod-code"
border="0" cellpadding="2" cellspacing="2">
<tbody>
<tr>
<td style="vertical-align: top;"> /**<br>
* Returns meta data that is interpreted by parent
class<br>
*<br>
* @return array array with meta data<br>
*/<br>
<span style="font-weight: bold;"> function</span>
get_metaData() {<br>
$return = array();<br>
// PHP extensions<br>
$return["extensions"] =
array("hash");<br>
[...]<br>
</td>
</tr>
</tbody>
</table>
