Array Error/Warning

Question

I am receiving the following warning:

Warning: reset() expects parameter 1 to be array, null given in /data/9/1/115/118/1767118/user/1910351/htdocs/aw/home/wp-content/themes/awthemesnew/library/sidebars.php on line 183

Keep in mind I am editing a wordpress .php file. Here is the full code on line 183:

function theme_print_sidebar($name, $places) {
    $style = theme_get_option('theme_sidebars_style_' . $name);
    $place_count = count($places);
    if ($name != 'footer' && $place_count < 2) {
        theme_print_widgets(reset($places), $style);
        return;
    }
    ?>

Help. Thanks!

The value of $places is apparently null by the time you call reset.

Your code is saying "only call reset when the value of $place_count is less than 2". You're setting the value of $place_count via the statement:

$place_count = count($places);

We can infer that when count() is called on a null variable it returns 0. Since 0 is less than 2, the following statement is executed:

    theme_print_widgets(reset($places), $style);

However, at this point the fact that $places is null is causing an error. I would be curious to know under what circumstances $places is null. Once you've got the answer to that you can decide how to handle that case.

I figured it out. I had erased a command in the footer and when the code when looking for it, since it was gone, it gave me a array warning. Thanks for the help.
