Does anyone know if there is a way to have the blog summary page only display the "show full post" link only if there is more to display than what is already being displayed.

many thanks

Hi-

You certainly can! I tried this...

In your BlogEntry.php file:

class BlogEntry extends Page {
   .
   .
   .
   function ShowFullPost() {
      if ($this->Content == $this->ParagraphSummary()) {
         return false;
      } else {
         return true;
      }
   }
}

In your /templates/Includes/BlogSummary.ss file:

   <p class="blogVitals">
      <a href="$Link#PageComments_holder" class="comments" title="View Comments for this post">$Comments.Count comments</a>
      <% if ShowFullPost %> | <a href="$Link" class="readmore" title="Read Full Post">Read the full post</a><% end_if %>
   </p>

This doesn't quite seem to work for me!

It always returns true , and displays the link

The ShowFullPost function is definitely being called, as if I reverse the true/false return values then it always returns false.

Any ideas what might be wrong?

Try using $this->ParsedContent() instead of $this->Content()

That gives the same result.

I think the problem is in the fact that the FirstParagraph() function in the Text class does all sorts of fancy substrings and stuff like that - so it will return a slightly different result. I think something like this would be a better solution, as it uses the same logic checking as the FirstParagraph() function when checking for new paragraphs:

Note I havent tested it with the blog module, but the algorithim itself should work.

class BlogEntry
{
   
   public function ShowFullPost()
   {
      if(self::$allow_wysiwyg_editing) {
         if(strpos($this->Content, '</p>') === false) return false;
         if(strpos($this->Content, '</p>') == (strlen($this->Content) - 4)) return false;
         else return true;
      } else {
         if(strpos($this->Content, "\n\n") === false) return false;
         if(strpos($this->Content, "\n\n") == (strlen($this->Content) - 2)) return false;
         else return true;
      }
   }
   
}

Edit: fixed up formatting

Well I struggled to get any of the previous suggestions to work and ended up with the following rough and ready solution.

class BlogEntry extends Page {
.
.
.
function ShowFullPost() {
if ( strlen($this->Content) > ( strlen($this->ParagraphSummary()) -7 ) ) {
return true;
} else {
return false;
}
}

.
.

}

This assumes (probably incorrectly) that the ParagraphSummary is simply the first paragraph wrapped in a <p>....</p> tag, hence the -7
