I get an error when I activate the plug in I've been working on.
error Wrote:Fatal error: Cannot use object of type MyLanguage as array in /home/teamrogu/public_html/forums/inc/plugins/socialgroups.php on line 78

I have a language file written for it that is titled socialgroups.lang.php and has the language defined.

The plug-in code:
<?php
if (!defined("IN_MYBB"))
{
	die ("Direct access to this file is not allowed. Please make use IN_MYBB is defined.");
}
function socialgroups_info()
	{

	return array(

		"author"		=> "Mark Janssen",
		"authorsite"		=> "http://www.teamdimensional.net",
		"version"		=> "1.0",
		"guid" 			=> "",

		);
	}

I'm sure its something simple I'm forgetting since this is the first time I've done a plug-in.

It's not $lang['name'] but $lang->name. The $lang variable is an object instead of an array.

Yaldaram

The problem is, you are using $lang variable as an array. This is incorrect. You've to use them as;
{$lang->group_name}

So your code will look like this; (I've debug some of the other code as well)
<?php
if (!defined("IN_MYBB"))
{
    die ("Direct access to this file is not allowed. Please make use IN_MYBB is defined.");
}

    {

    return array(
        "name"        => "Social Groups",
        "description"        => "A plug-in that lets users create their own groups and control various settings.",
        "website"        => "http://www.teamdimensional.net",
        "author"        => "Mark Janssen",
        "authorsite"        => "http://www.teamdimensional.net",
        "version"        => "1.0",

And looking through your code there is a problem, as well as in the code of Yaldaram btw.
If you use the dollar sign between double quotes, PHP puts the value of the variable in the string and not the actual literal variable name. Here an example what I mean:
$var = "hello";
print "$var world"; // prints out "hello world"
In your templates you want to have the variable name and not the value to make it dynamic. So you either have to use single quotes or escape your dollar signs if you want to use literal:
$var = "hello";
print "$var world"; // prints out "hello world"
print "\$var world"; // prints out "$var world"
print '$var world'; // prints out "$var world"

Thanks for the responses. I'll work on my code and see how it goes.

edit: Now I have a parsing error.
$new_template['groups'] = '<html>
		<head>
		<title>
		Groups
		</title>
	{$headerinclude}
	</head>
	<body>
	{$header}
	{$groupadd}
	<table width="100%" border="1">
	<tr>
	<th class="thead">{$lang->group_name}</th>
	<th class="thead">{$lang->group_leader}</th>
	<th class="thead">{$lang->group_discussions}</th>
	<th class="thead">{$lang->group_description}</th>
	</tr>
	{$grouplist}
	</table>
	{$groupcreate}
	<form action="{\$settings['bburl']}/groups.php" method="post">
	<input type="hidden" name="action" value="create" />
	<input type="submit" value="{\$lang->create_group}" /></form>
	{$footer}
	</body>
	</html>';

The line it doesn't like is <form action="{\$settings['bburl']}/groups.php" method="post">. I can't figure out why it doesn't like it.

Try this in form action URL;
<form action="groups.php" method="post">

Aries-Belgium

2011-05-06, 05:13 PM
You need to also escape your single quotes for the array:
<form action="{$settings[\'bburl\']}/groups.php" method="post">

If you use single quotes, you don't need to escape your dollar sign. Just think of it as single quotes take the literal value of the string, double quotes parses variables.
