Great post but I’m confused, can’t figure out where to change the one of my categories to the example above, can you give another example please ie. cat id 28.

thanks

get_the_title() and get_permalink() are same as the_title() and the_permalink() except one uses return and the other uses echo. Inside of a theme the ones that echo are used, not the ones that return. Those that return are for specific cases as in this one where i need to get and not echo the value.

I usually downvote first, then come back to see if the article is changed or they have a good argument to convince me their way is good/better.

2) You should not assume how the output will be used. With this function you have to use output buffer to capture it if you want to use it for something else.
You see the functions get_the_title() and get_permalink() return a string and can be used in string concatenation. Its better to be consistent.

@OIS – After you write a comment think about it before you hit the submit button. That way you won’t make 3 comments in 20 seconds. I’ll make them into one but in future take it slowly

1) Interesting.
2) Well for this specific wordpress function i think echo is the way to go.

P.S. Thanks for the downvote.

For simple lookups you use an array not a switch.

static $text = array(
‘default’ => ‘Continue Reading’,
1 => ‘Continue reading this tutorial’,
2 => ‘Watch screencast’,
);
if (!isset($text[$categoryID])) {
$categoryID = ‘default’;
}
$readMoreText = $array[$categoryID];

Secondly, it should return a string so you dont have to use output buffer to capture it. Its a good practice for the future.

function readMore()
{
//do stuff

return $readMore;
}

echo readMore();
