Setting Maximum number of words a user can input into a post?

[raindahl]

Hi there ,

I am new to Genesis themes and forums and would like to say hello !

I am looking for help , basically I am building a website and my boss only wants there to be a limit of say 300 words that a user can input in a post/page and I have looked for plugins or code and have so far not found any ! The only ones really that I have found reduce the excerpt and the post title and I have tried to modify some of them but have had no joy

This is the code I have been working on which I hoped would work :

function maximum_number_words($content)
{
	global $post;
	$content = $post->post_content;
	if (str_word_count($content) > 300 )
	wp_die( __('The current post is above the maximum number of words, it must be under 300 words.') );
}
add_action('publish_post', 'maximum_number_words');

If anyone can help me with where I am going wrong or suggest a plugin it would be much appreciated because this is the last thing I have to do on the site!

Thanks

I'm not the expert in this stuff but I'm pretty sure that you are using the wrong function - publish_post happens too late (it's only triggered when the post has actually been published). Instead, I think you want to filter the content before save. Try this:

Hi There ,

Got it working just made a slight alteration to the code "publish_post" works fine now using this code :

<?php
function maximum_number_words($content)
{
	global $post;
	$content = $post->post_content;
	if (str_word_count($content) > 400 )  // maximum amount of words 
	wp_die( __('The current post is above the maximum number of words, it must be under 400 words ') );
}
add_action('publish_post', 'maximum_number_words');
?>
