External PHP page (on same domain) only accessible for logged in members.

Hello,

as the title says, I am looking for a simple way to have an external PHP page (rendering HTML) but only accessible/readable when the visitor is a member and logged in.

What would be the best way for me to do that?
Thank you.

Best regards,
Esteffano

There are several ways to do this.  I'll provide a quick example below, you would place this in a xyz.php file in the same directory as you SSI.php  Read the comments I provided in the script for futher details

Code: [Copy]
<?php

/**
 * Define $ssi_guest_access variable before including SSI.php to handle guest access to your script.
 * false: follows the forum setting of "Allow guests to browse the forum"
 */
$ssi_guest_access = false;

// Include the SSI file.
require(__DIR__ . '/SSI.php');

/**
 * If you have "Allow guests to browse the forum" enabled but still do not want guest to access this script
 * then use the is_not_guest(); function after including SSI.  If they are a guest their journey ends at the next line.
 */
is_not_guest();

echo '<!DOCTYPE html>
<html>
	<head>
	</head>
	<body>
		Guests can not see this
	</body>
</html>';

In both cases they will be redirected to the login screen

Wow, thank you.
This really helps me do what I want.

Is there also a way to make the output only visible to a certain group (based on group ID)?

Sure, I'll show you a quick snip that should work.   But first a notice.

The permission system is based on named permissions and not simple group access.  This is because being in a group may be additive or may be subtractive to your permissions.  You could be in a group and "loose" permissions.  So with that warning out of the way ...

Code: [Copy]
<?php

/**
 * Define $ssi_guest_access variable before including SSI.php to handle guest access to your script.
 * false: follows the forum setting of "Allow guests to browse the forum"
 */
$ssi_guest_access = false;

// Include the SSI file.
require(__DIR__ . '/SSI.php');

/**
 * If you have "Allow guests to browse the forum" enabled but still do not want guest to access this script
 * then use the is_not_guest(); function after including SSI.  If they are a guest their journey ends at the next line.
 */
is_not_guest();

global $user_info;

$exists = false;

// 1 is the admin, always allowed
// 2 is a global moderator, generally allowed
// 99 is just some group id that you have defined
foreach ([1, 2, 99] as $value)
{
	if (in_array($value, $user_info['groups'], true))
	{
		$exists = true;
		break;
	}
}

if (!$exists)
{
	redirectexit();
}

echo '<!DOCTYPE html>
<html>
	<head>
	</head>
	<body>
		Guests can not see this
	</body>
</html>';

Here you provide a list of allowed groups, is put in 1, 2, 99 as an example, and the code simply checks if you are in one of those groups.  But as I stated this simply means your in a group, not that a necessary you have some permission, it all depends on how you have setup your forum.  But for simple cases its just OK, certainly not ideal.

Thank you again,

it really worked well.

I made a little function based on you code to simplify working with the mechanism.

Code: [Copy]
<?php

$ssi_guest_access = false;

// Include the SSI file.
require(__DIR__ . '/SSI.php');


/**
 * isVisitorLoggedIntoGroup
 *
 * Check whether or not visitor is in at least one of specified groups
 * @param mixed $mGroups may be string or array
 * @return bool TRUE if is in any of the groups, FALSE if in none at all
 */
function isVisitorLoggedIntoGroup($mGroups) {
    global $user_info;

    // Ensure $mGroups is always an array
    $groupsToCheck = (is_array($mGroups)) ? $mGroups : [$mGroups];

    // Check if the user is in any of the specified groups
    foreach ($groupsToCheck as $group) {
        if (in_array($group, $user_info['groups'], true)) {
            return true;
        }
    }

    // If none of the specified groups match, return false
    return false;
}

echo 'Something anyone can see.<br>';

// Check if the user in any of the specified groups
$allowedGroup = isVisitorLoggedIntoGroup([1, 2, 99]);
if($allowedGroup){
	echo 'Something that\'s only meant to be seen by $allowedGroup.';
} else {
	echo '<a href="#">Login</a>';
}
