Select one context from the list of contexts, accounting for changed IDs.

Fundamentally, this returns $contexts[$context] or FALSE if that does not exist. Additional logic accounts for changes in context names and dealing with a $contexts parameter that is not an array.

If we had requested a $context but that $context doesn't exist in our context list, there is a good chance that what happened is the context IDs changed. Look for another context that satisfies our requirements, unless $skip_name_check is set.

Parameters

ctools_context|array $contexts: A context, or an array of ctools_context.

string $context: A context ID.

Return value

bool|ctools_context The matching ctools_context, or False if no such context was found.

Class

ctools_context_required

Used to create a method of comparing if a list of contexts match a required context type.

Code

public function select($contexts, $context) {
    // Easier to deal with a standalone object as a 1-element array of objects.
    if (!is_array($contexts)) {
        if (is_object($contexts) && $contexts instanceof ctools_context) {
            $contexts = array(
                $contexts->id => $contexts,
            );
        }
        else {
            $contexts = array(
                $contexts,
            );
        }
    }
    // If we had requested a $context but that $context doesn't exist in our
    // context list, there is a good chance that what happened is the context
    // IDs changed. Check for another context that satisfies our requirements.
    if (!$this->skip_name_check && !empty($context) && !isset($contexts[$context])) {
        $choices = $this->filter($contexts);
        // If we got a hit, take the first one that matches.
        if ($choices) {
            $keys = array_keys($choices);
            $context = reset($keys);
        }
    }
    if (empty($context) || empty($contexts[$context])) {
        return FALSE;
    }
    return $contexts[$context];
