OVERVIEW
========
Hide submit module provides a way to hide the submit button in forms after
it has been clicked. This helps to prevent duplicate postings from people who
accidentally double click (or triple click) on a submit button.

The 7.x-2.x version of this module aims to be extremely lightweight yet
extensible to handle all additional features. If you have an idea for additional
features it probably should be contributed as a sub-module and, if necessary,
a patch to the main module to make it alterable (e.g. via a hook_alter or
theme_ function).

CREDITS
=======
The current version is based on block_submit module.

The original hide_submit jQuery snippet was taken from Ted Serbinski's blog

INSTALLING AND CONFIGURING
==========================
Browse to admin/modules and enable the module.

You can configure it at admin/config/content/hide-submit

There are no module dependencies and no database tables created.

Uninstalling the module will remove the variables created by the module.

ADVANCED CHANGES
================
You can alter the style of affected buttons by overriding css rules. The two
css style rules to consider are:

div.hide-submit-disable - for disabled buttons.
div.hide-submit-processing - for hidden buttons.

There are two hidden variables for the values of the css classes. You can modify
these by setting a variable in the $conf array in your settings.php or using the
drush vset command. The variables are: hide_submit_css and hide_submit_hide_css.

The module calls a hook (hook_hide_submit_alter) to let other modules modify the
behavior of the module. This could be used, for example, to create a random
image effect by tweaking the css styles on each page load.

The hidden variable hide_submit_status allows a site to enable or disable the
module. This is most useful as part of the hook_hide_submit_alter to disable
the module on certain pages.

See hide_submit.api.php for an example implementation of hook_hide_submit_alter.
