get_the_content WITH formatting

I’ve been trying to highlight the first post and one of the things I needed to do was to get the layout in a specific manner which was to have an image from the post extracted and inserted before the headline. That wasn’t much of a problem with a little preg_match.

However the next issue is where I’m stumped right now. Since I already have an image representing the post, i need to get the rest of the post WITH formatting, without images and stopped before the  tag. The only way I know that I get a formatted text is via the_content(). But since I can’t process the_content() and $post->post_content and get_the_content() are not giving me formatted text, I’m kinda stuck as to how to proceed further.

I can do a preg_replace or strip_tags to replace images if i can get a formatted string terminated before . But I need that formatted string.

Thanks in advance…

Nevermind… managed to do some more preg_replace to replace the carriage returns with  tags. Works fine now 🙂

Thanks for the tip.

Here’s how I did it:

<?php echo str_replace("\r", " ", get_the_content('')); ?>

There is actually a simpler and more efficient way to control formatting in WordPress posts. Take a look how…

The default template, inside single.php has this php code to request the post content:
```
<?php the_content('Read the rest of this entry &raquo;
'); ?>
```
If we wanna fully control the output, we call get_the_content instead of just the_content. get_the_content outputs a string, so it’s easier to manipulate it than the_content (which is not a string):
```
<?php echo strip_tags(nl2br(get_the_content('')),"<img><a>"); ?>
```
In the above example, I’m fetching the post content, create br’s from the carriage returns put by WordPress and then strip all tags except the once specified at the end (<img><a>) . I make sure to add there again, so it won’t be stripped (obviously).

Hope this helps someone. 😉

I have solved this problem like the WordPress team did in the core. Read my article at get_the_content() WITH formatting to find out.

@jenst – thank you! But this renders the use of my ‘Visual/HTML’ tabs, in the back-end posts, broken. Is there a specific place in the functions.php file I should paste this code?

Cheers Jenst!

You don’t have to re-invent the wheel.
(Or hack the core…)

Just use output buffering:

function ob_wp_content($display = true) {
global $post;
ob_start();
the_content();
$output = ob_get_contents();
ob_end_clean();
if(!$display) {return $output;} else {print $output;};
}

Also, wrap the $output so you can choose a simple “$display” flag to make this function either a “getter” or a “printer.” Wrap all the WP functions this way to maintain standards throughout your templates.
