<glossterm>args</glossterm>
<glossdef>
<para>Array of optional arguments set by phpldapadmin.
It is normally in a form known by
call_user_func_array() :
<programlisting>[ 'server_id' => 0,
'dn' => 'uid=epoussa,ou=tech,o=corp,o=fr' ]</programlisting></para>

<section>
<title>Usage</title>
<para>Runs procedures attached to a hook. This is normally
called from the phpldapadmin code. But user can define hooks
in her code if needed.</para>
<para>The mechanism is quite simple : hooks are added via the
<function>add_hook()</function> function, using a numeric
priority to sort order or invocation. The
<function>run_hook()</function> function will run them
sequentially from the lowest priority to the highest priotiry
untill a procedure returns a non true value. In that case,
rollbacks procedures that are defined together with procedures
are executed in reverse order. Rollbacks are mainly used to
keep consistency and achieve failsafe systems.</para>
<example>
<title>Example of invocation of run_hook.</title>
<para>Phpldapadamin runs a hook that contains three
procedures, a, b, c and d of priority 0, 10, 20 and 30.
Procedure a is executed first and after that, b is executed
if no error occurs. If b does not returns an error, c is
executed. Now, let imagine that c returns false. In that
case, c's rollback is executed, then b's rollback and
finally a's rollback.</para>

<para>This hook is triggered by phpldapadmin after user has

update array of changes is build and its content is displayed
into the commit form. As a reference of this update array is
passed to this hook, it is possible to add, remove or change
entries from it, thus allowing some manual tweaking before
data is passed to phpldapadmin.</para>
<para>An additional reference to a the number of rows already
displayed is passed, allowing hook to change its behaviour,
like displaying different color for odd or even rows.</para>

<title>Usage</title>
<para>This hook is triggered by phpldapadmin after user has
modified attributes in the editing form and before she commits
changes in the confirmation form. This hooks is run BEFORE an
update array of changes is build and its content is displayed
into the commit form. As a reference of this update array is
passed to this hook, it is possible to add, remove or change
entries from it, thus allowing some manual tweaking before
data is displayed in commit confirmation form.</para>
