Multiple ob_start ‘s in WordPress

Hi,

I’m trying to write some custom plugin code, the ultimate end result will be that I can “program” in php, and my “author” can then call the code from within posts with {key_words}. I get that in the following example plugins are avilable to list_pages etc, but this will devlop into “odd” requests from my author.

Please consider the following code which executes fine outside of wordpress….

function wp_recent_posts() {

                ?>recent post<?php
}

function wp_page_list() {

                ?>page list<?php
}

function wp_recent_posts_inline( $content ) {

        ob_start(); // Enable output buffering to supress echos

        wp_recent_posts(); // run function

        $result = ob_get_contents();

        ob_end_clean(); // Empty the Buffer

        echo str_replace("{wp_recent_posts}", $result, $content);

}

function wp_page_list_inline( $content ) {

        ob_start(); // Enable output buffering to supress echos

        wp_page_list(); // run function

        $result = ob_get_contents();

        ob_end_clean(); // Empty the Buffer

        echo str_replace("{page_list}", $result, $content);

}

$content = " abc {page_list} cde " ;
wp_page_list_inline($content);
$content = " 123 {wp_recent_posts} 456";
wp_recent_posts_inline($content);

Now replace

$content = " abc {page_list} cde " ;
wp_page_list_inline($content);
$content = " 123 {wp_recent_posts} 456";
wp_recent_posts_inline($content);

with

add_filter('the_content', 'wp_page_list_inline');
add_filter('the_content', 'wp_recent_posts_inline');

upload the code & activate the plugin, write a page / post with the words {page_list} and {wp_recent_posts} in .

In my experience {page_list} will work but {wp_recent_posts} will not, if you change

add_filter('the_content', 'wp_page_list_inline');
add_filter('the_content', 'wp_recent_posts_inline');

for

add_filter('the_content', 'wp_recent_posts_inline');
add_filter('the_content', 'wp_page_list_inline');

i.e. swap the add_filter statements over, the opposite will happen… can anyone offer any advise ? ( as I’d like both to work) ??

Cheers,
Nick
