Question

I have the following function, which at the moment is in the default.php file, which I will later on move to the helper.php

function getauthor($shouts, $i){
    $db = JFactory::getDBO();
    $query = $db->getQuery(true);
    $query->select('*')
    ->from('#__users')
    ->where('name = '. $shouts[$i]->name);
    $db->setQuery($query);
    $rows = $db->loadObjectList();
    $i=0;
    foreach ($rows as $row){
        $author[$i]->id = $row->id;
        $author[$i]->name = $row->name;
        $i++;
    }
    return $author;
}

Basically what I want to do is, print $author[$i]->name, but every time I try and do this using the following code:

print stripslashes($author[$i]->name);

I get the following errors:

Undefined variable: author in C:\wamp\www\Joomla25\modules\mod_xxx\tmpl\default.php on line 98

Trying to get property of non-object in C:\wamp\www\Joomla25\modules\mod_xxx\tmpl\default.php on line 98

Cannot redeclare getauthor() (previously declared in C:\wamp\www\Joomla25\modules\mod_xxx\tmpl\default.php:60) in C:\wamp\www\Joomla25\modules\mod_xxx\tmpl\default.php on line 60

Can anyone show me where I am going wrong and how to print $author[$i]->name?

Answer 1

You need to have the variable author defined in the place where you call:

print stripslashes($author[$i]->name);

In the smallest possible example:

$author = getauthor(....)
...
print stripslashes($author[$i]->name);
