Blog - show full post
29 August 2008 at 9:46am
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()

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
