I'm using Wordpress as headless CMS.

I use the following function to return a page based on the page title.

No code or Wordpress content has changed and suddenly it has stopped working...

Almost indentical code on the same server on a different site is working fine.

Anyone got any ideas what might have happened ?

// -- Get page based on page name -- //
    function getWordpressPage($wordpressPageName){
        $page = NULL;
        $pageRequest = cleanUrlVar($wordpressPageName);
        if($pageRequest){
            $page = get_page_by_title( $pageRequest );
            if($page != NULL){
                setup_postdata($page);
                return the_content();
            }
        }
        if($page == ''){
            header('Location: /');
            exit();
        }
    }

FYI - var_dump($page) returns the data so Wordpress is returning something, it looks like it's falling over at the 'return the_content() stage...

CodePudding user response：

the_content() will show the content by echo it. So if you want to get variable to return, you should use get_the_content()

Update your codes to return it:

return get_the_content();

You can find out more here:

CodePudding user response：

You don't even need setup_postdata. By using get_page_by_title, you'll get the entire page object.

get_page_by_title^Docs

function getWordpressPage($wordpressPageName)
{
  $page = NULL;
  $pageRequest = cleanUrlVar($wordpressPageName);
  if ($pageRequest) {
    $page = get_page_by_title($pageRequest, ARRAY_A);
    if ($page != NULL) {
      return $page['post_content'];
    }
  }
  if ($page == '') {
    header('Location: /');
    exit();
  }
}

Note:

• cleanUrlVar is a custom function you're using, so make sure it works.
• I used ARRAY_A in get_page_by_title to get the results in array format

Possible alternative, using setup_postdata

setup_postdata will accept post object or post id not page title. So you could use the post global variable and pass it to the setup_postdata. Although this would work, but, probably you don't even need to do that.

setup_postdata^Docs

function getWordpressPage($wordpressPageName=''){
   global $post;

   setup_postdata($post);

   $content = get_the_content();

   return $content;        
}
