<b>Warning!</b> This module requires technical knowledge of PHP, Smarty templating or in the very least HTML.
<h4>So what does this module do?</h4>
The Hooks Manager module provides you with a simple interface to add your own code or
HTML/Smarty markup allowing it to appear in Form Tools pages, or have it executed at
particular junctures in the code. What code you choose to add depends entirely on your
Form Tools has dozens and dozens of "hooks" littered throughout the code and within
the Smarty templates used to generate the visible webpages. These allow
developers like yourself to develop modules that extend the core functionality and
display extra information in the UI.
Like to add new fields to any of the Form Tools pages? Like to send emails to notify
yourselves when specific users change specific values in the form submissions? Like
to know when users are exporting data? No problem! All of this - and far, far more,
can be done relatively simply by using this module. To give you another idea, from a
technical standpoint the entire functionality offered by the Submission Pre-Parser
and Extended Client Fields modules could be emulated using the Hooks Manager. They
were implemented as separate modules since they're easier to handle that way.
<h4>Hooks Manager vs. custom modules</h4>
<b>This module adds nothing that can't be done via a custom module</b>. But writing a
separate module can be a bit of an uphill struggle: it requires learning about how
the Form Tools module system works which can take time. Plus, often you don't
need a UI for whatever it is you're doing: sometimes you just want something simpler;
sometimes you don't need a pretty UI to allow people to use and configure it.
The basic difference is that for larger functionality - functionality that requires
an interface for configuring its behaviour, you should run the gauntlet and
learning about how modules work. But for OTHER uses, the Hooks Manager may well be
a better fit.
To help you understand what this module can do, I'll provide a lot of examples
in this documentation. They should give you a clue of two things: how powerful it
is, and what kind of things it can do.
We'll start with a simple examination of the Hooks Manager UI: how you can utilize it
to solve your problem.
