Don't disable plugins on the "Admin/Plugins"-tab

Benefits:

  • keep the “Extensions”-tab always visible
  • allow plugins like the indispensible soo_editarea to work on “Admin/Plugins/Edit”

To tame amok-running plugins there’s a parameter: with an URL like

http://example.com/txp/textpattern/index.php?event=plugin&plugins=0

you get to your “Admin/Plugins”-page with all plugins disabled. This works only for privs 1 and 2 (‘publisher’ and ‘managing_editor’), since we don’t want to allow the lower ranks to disable a possible security related plugin.

Instructions

In file textpattern/index.php find the line saying

	if (!empty($admin_side_plugins) and gps('event') != 'plugin')

(should be #118) and replace it by

	// TODO: Find all the other lines looking *exactly* like this one and use $GLOBALS['txp_privs'] instead
	$txp_privs = safe_field("privs", "txp_users", "name = '".doSlash($txp_user)."'");
	$no_plugins = (gps('plugins')==='0' && in_array($txp_privs, array(1, 2))) ? '&plugins=0' : '';

	if (!empty($admin_side_plugins) && empty($no_plugins))

In file textpattern/include/txp_plugin.php find the line saying

	$status.'&name='.urlencode($name).'"';

(should be #251) and replace it by

	$status.'&name='.urlencode($name).$GLOBALS['no_plugins'].'"';

In file textpattern/lib/txplib_misc.php find the block saying

	if (!isset($GLOBALS['event']) || ($GLOBALS['event'] !== 'plugin'))
	{
		$plugin_areas[$area][$title] = $event;
	}

(should be at #43), remove the “if”-line and the curly brackets, so that only

	$plugin_areas[$area][$title] = $event;

remains.

The same as a patch:
