function drupal_set_page_content

Sets the main page content value for later use.

Given the nature of the Drupal page handling, this will be called once with a string or array. We store that and return it later as the block is being displayed.

Parameters

$content: A string or renderable array representing the body of the page.

Return value

If called without $content, a renderable array representing the body of the page.

function drupal_set_page_content($content = NULL) {
    $content_block =& drupal_static(__FUNCTION__, NULL);
    $main_content_display =& drupal_static('system_main_content_added', FALSE);
    if (!empty($content)) {
        $content_block = is_array($content) ? $content : array(
            'main' => array(
                '#markup' => $content,
            ),
        );
    }
    else {
        // Indicate that the main content has been requested. We assume that
        // the module requesting the content will be adding it to the page.
        // A module can indicate that it does not handle the content by setting
        // the static variable back to FALSE after calling this function.
        $main_content_display = TRUE;
        return $content_block;
