[Solved] Expressing WP’s the_content as a function and checking isset

[Eamonn]

Hi guys, to jump straight in, I am trying to work with WP’s the_content() tag, expressed as a function.







The above expresses the_content as $content and outputs the text fine. What I want, however, is to check whether there is any actual text within the_content() and change the container div’s styling accordingly.

I have tried to do this with the following…




echo "

";
} else {
echo "

";
}
?>

… but it has the effect of returning the content without any wrapping div (just

tags), and then opening and closing an empty div afterwards:

the_content text here

Any help is, as always, greatly appreciated.

P.S I tried doing this using a PHP string word count, but it would only return ‘0’ as the number of words…

Ahh. Here’s the answer:

The final code looks like this:

the_content();
$content = ob_get_clean(); ?>

echo "

";
} else {
echo "

";
}
?>

This now lets me apply margins, padding, etc. to a container only if it will be actually filled with content. Otherwise, empty div! Thanks Chris!

You could also use the get_the_content() function to return the content of the post to a variable instead of having to initialize a buffer.

<?php



$content = get_the_content();



if ($content != '') {

echo '<div>' . $content . '</div>';

}



?>

Just saw this now – nice one!
