Question

i want to make a wordpress plugin that will display some content at the end of each post. let’s say for example ‘Hello world’.
But looking at the wordpress API, i don’t find any relevant indications about how to do this.

i don’t want a widget, but only a plugin that does only that: displays me a static text at the end of every article.

any idea about how this should be done?

thanks!

See if this forum post helps you:

The lines doing the magic are:

...
add_filter('the_content','now_what_pjrvs');
...
function now_what_pjrvs($content = '') {
       return $content . $text;
}

Where $text is the code that you want to add at the end of the post content.

Hope it helps.
