$language->title not displaying?

[Godfrey]

This is probably horrendous code, but why is it that $language->title in the following code block won't display?

$savedLanguage = $user->language; 

 

   if( $savedLanguage->id == $languages->get("default")->id){

      $user->language = $languages->get("english"); 

  } else {

    $user->language = $languages->get("default");

  }

 

  echo "<li><a href='$page->url'>$language->title: $page->title</a></li>";

  

$user->language = $savedLanguage;

This probably isn't the most elegant code, but I wanted to simply switch between two languages. 
However, if I use the given (default) code below, $language-title is displayed. 
 

// remember what language is set to

$savedLanguage = $user->language; 

 

foreach($languages as $language) {

 

  // if user is already viewing the page in this language, skip it

  if($language->id == $savedLanguage->id) continue; 

 

  // if this page isn't viewable (active) for the language, skip it

  if(!$page->viewable($language)) continue;

 

  // set the user's language, so that the $page->url and any other

  // fields we access from it will be reflective of the $language

  $user->language = $language; 

 

  // output a link to this page in the other language

  echo "<li><a href='$page->url'>$language->title: $page->title</a></li>";

}

// restore the original language setting 

$user->language = $savedLanguage; 

 

This seems really weird, because the echo statements are exactly identical. For both, $page->title works. I'm also curious as to how $page->title and $language->title are printed even though they are not escaped from the double quotes in the echo statement...

Thanks for any help! This is probably a rookie error, I just can't seem to find it...

Your first non-working code block doesn't foreach through the $languages array and so $language is probably never defined.

As for the variables being printed in the double quotes - that is how php works. In double quotes it works as is. In single quotes you need to do something like:

echo '<li><a href="'.$page->url.'">'.$language->title.': '.$page->title.'</a></li>';

Hope that helps.

Ah, I knew about the single quote method but didn't know about the double quotes.

Yep, this helped! Indeed I got it to work after changed $language-title to $user->language->title. I know I missed something. Many thanks adrian.
