[Plugin: Shortcode Exec PHP] Shortcode posts as text

What do you mean by “it simply posts as text” ?
How is your shortcode defined?

Hi, Marcel:

I am using the default shortcode that was included with your plug-in.

extract(shortcode_atts(array('arg' => 'default'), $atts));
echo "Hello world!" . PHP_EOL;
echo "Arg=" . $arg . PHP_EOL;
echo "Content=" . $content . PHP_EOL;

If you check the site, I have examples executing (or attempting to execute) the code in both posts and pages.

I don’t see anything wrong. ‘hello_world’ is the name of the plugin, so you should use the shortcode [hello_world] in your posts or [hello_world arg="Bob"]).

I think that I see the problem.

Instead of

[shortcode arg="hello_world"]

I should be doing this

[hello_world arg="Joe"]

This is what happens when I attempt to work on my site late at night when I should be in bed. ??

Thanks, Marcel!

Maybe the argument should have been called ‘Arghhh’ ??

Haha, yeah, it was coming to that! ??

Thanks again!
