Error on PHP 5.4.0

this is true but it should be a simple fix; I do not use this plugin however PHP now defaults to passing by reference, so theres nothing wrong with the way the function is defined but there is a problem with the way it is called now!

New versions of PHP no longer require a pass by reference to implicitly require the & before the variable when passed as a param.

the simple fix: Edit the line near 646 that passes the ‘this’ object by reference. Change &$this to just $this (php knows its passed by reference because the function should declare it).

You will also need to edit line 995 and do the same thing.

this was done in new version of php for code cleanliness – basically the function declaration decides how the variable is passed, not the caller.

I have edited the reference & have gotten past the fatal error and now the plugin can activate, however there are even more problems with this plugin. Once this error was corrected, my site now renders correctly when logged in. However, when not logged in, I get warnings on the main page.

Warning: Creating default object from empty value in …/wp-content/plugins/user-access-manager/class/UamAccessHandler.class.php on line 678

Line 678 is part of this function call:

/**
     * Return the role of the user.
     *
     * @param integer $userId The user id.
     *
     * @return string|null
     */
    private function _getUserRole($userId)
    {
        global $wpdb;

        $curUserdata = get_userdata($userId);

        if (!isset($curUserdata->user_level)) {
            $curUserdata->user_level = null;
        }

        if (isset($curUserdata->{$wpdb->prefix . "capabilities"})) {
            $capabilities = $curUserdata->{$wpdb->prefix . "capabilities"};
        } else {
            $capabilities = null;
        }

        $role  = (is_array($capabilities) && count($capabilities) > 0) ? array_keys($capabilities) : array('norole');

        return trim($role[0]);
    }

Specifically the “$curUserdata->user_level = null;” line.

Your help is greatly appreciated!

I have disabled all error reporting which has returned my home page to it’s former state & everything seems to be working as it should, but I would like to know how to fix this appropriately.

Hello.
Thanks for this information, I could activate this plugin.
But I still have the same worning, such as

Warning: Creating default object from empty value in …/wp-content/plugins/user-access-manager/class/UamAccessHandler.class.php on line 678

So I did change the line 678 and warning was stopped.
I’m not sure if this workaround is correct or not…

if (!empty($curUserdata->user_level) && !isset($curUserdata->user_level)) {
/* if (!isset($curUserdata->user_level)) { */
$curUserdata->user_level = null;
}

Trying to use this plugin results in the error:

Fatal error: Call-time pass-by-reference has been removed in /home/mdowning/Projects/data/itso/htdocs/wp-content/plugins/user-access-manager/class/UamUserGroup.class.php on line 646

I tried to remove the ‘&’ from line 646 and 995, but then it shows error as Plugin activation shows a Fatal error and no error description. I have updated my xampp for linux to xampp version 1.8.1 which has php version 5.4.7. Can you tell me if any other change is required?

I was receiving the same error, but I after changing:

&$this

to

$this

on lines 645 and 994, it worked

Hello,

I made the changes posted by jloosli in UamUserGroup.class.php and it worked for me too.

Fixed since version 1.2.3
