Wordpress Gurus

Is it possible for a plugin to capture the text of a post someone has just entered in their posts area then perform an operation on that text before it gets placed into the database ?

Examples, taking the text and adding or removing elements, taking the text and adding or removing particular words or phrases ?

Pretty much anything on the web is possible if you have programming skills and unlimited time.

With that being said... Good Luck! :thumbsup

Sure, you can hook into the save_post action.

Heh, I just glanced across the areas I could hook into, obviously I should have been more thorough. Thanks Brujah :thumbsup

Hmm, content_save_pre might be closer to what you need according to this:
http://wordpress.stackexchange.com/q...-prior-to-save

WordPress StackExchange has filled out really well with a lot of great information about customizing WP.

Thanks for this, you're spot on. I had only just come to that conclusion myself after reading the replies to this:

http://wordpress.stackexchange.com/q...re-it-is-saved

I'm well on the way now. I hardly ever write any plugins myself but I just needed to whip something up for testing an idea real quick

thanks for the responses

Easily. I just made some custom plugin which attaches a featured image to every new post basing on the keywords in its title.

Yep, took me 2 minutes once I found the right hook.

Pity you didn't learn enough to fund your own retirement, instead leaching off the British taxpayers who did. :2 cents:

Thank you

you want wp_insert_post_data

i did this, so when you publish a post it took you back a year ;)

Code:

function back_to_the_future($data,$postarr) {

            $format = 'Y-m-d H:i:s';

        $old_date = $data['post_date'];

        $old_date_gmt = $data['post_date_gmt'];

            $new_date = date($format, strtotime('-1 year',strtotime($old_date)));

            $new_date_gmt = date( $format, strtotime('-1 year',strtotime($old_date_gmt)));

        $data['post_date'] = $new_date;

        $data['post_date_gmt'] = $new_date_gmt;

            return $data; 

} 



add_filter('wp_insert_post_data','back_to_the_future',99,2);

in your case you would want to use post_content

like so

Code:

function change_post_content($data,$postarr) {

        $post_content = strip_tags($data['post_content']);

        $data['post_post_content'] = $post_content;

            return $data; 

} 



add_filter('wp_insert_post_data','change_post_content',99,2);

which would strip html tags from post content, etc.

this will get you started.

Hey, thanks heaps for that fris.

Just for anyone else who is interested in the solution here, based on fris' excellent example this is changing the post content, you could replace ucwords with any function or series of functions to modify your post content.

Code:

<?php

/*

Plugin Name: Your own Plugin

Plugin URI: http://someurl.com

Description: Converts the fist letter of every word to upper case.

Author: Your Name

Version: 1.5

*/



function change_content($data,$postarr) {

            $old_content = $data['post_content'];

            $new_content = ucwords($old_content);

            $data['post_content'] = $new_content;

            return $data; 

} 



add_filter('wp_insert_post_data','change_content',99,2);





?>
