Helb building a newsTicker plugin

  • Hi !

    I am writing a plugin that displays links to the latest posts via aScroller Javascript newsTicker.

    To achieve that, I want that everytime a post is published the plugins generates a text file with the content extracted from the lasts posts.

    with the code below, I am able to generate the file, but it still outputs me an error:

    Warning: Cannot modify header information – headers already sent by (output started at /Applications/MAMP/htdocs/decideursTV2/wp-includes/link-template.php:5) in /Applications/MAMP/htdocs/decideursTV2/wp-includes/pluggable.php on line 694

    here is my code:

    <?php
/*
Plugin Name: NewsTicker
Plugin URI: https://
Description: Récupère Flux RSS et met en forme et en cache un fichier texte exploité par le ticker.
Author: Nicolas Roos
Version: 0.1
Author URI: https://

*/

add_action('wp_head','addAscroller');

add_action('publish_post','update_ticker');

function addAscroller() {
	echo '<script src="'.bloginfo('blog_url').'/wp-content/nesTicker/aScroller-1.0.js"></script>';
}

function update_ticker() {
	$tickerContent = '';
	$my_query = new WP_Query('showposts=20');
	while ($my_query->have_posts()) : $my_query->the_post();
	$do_not_duplicate = $post->ID;
	    	$tickerContent .= '<a href="'.the_permalink().'" title="'.the_title().'">'.the_title().'</a>&nbsp;&nbsp;-&nbsp;&nbsp;';
 	 endwhile;

	$tickerFile = bloginfo('url')."/newsTicker.txt";
	$fh = fopen($tickerFile, 'a');
	fwrite($fh,$tickerContent);
	fclose($fh);
}
?>

    I am sure someone can help me. Maybe It’s the Javascript include that’s causing the problem…

    I got it working with this code

    <?php
/*
Plugin Name: NewsTicker
Plugin URI: https://
Description: Récupère Flux RSS et met en forme et en cache un fichier texte exploité par le ticker.
Author: Nicolas Roos
Version: 0.1
Author URI: https://

*/

add_action('wp_head','addAscroller');

add_action('publish_post','update_ticker');

function addAscroller() {
	echo '<script src="'.bloginfo('blog_url').'/wp-content/nesTicker/aScroller-1.0.js"></script>';
}

function update_ticker() {
	$tickerContent = '';
	$my_query = new WP_Query('showposts=20');
	while ($my_query->have_posts()) : $my_query->the_post();
	$do_not_duplicate = $post->ID;
		$title= the_title("", "", false);
	    $tickerContent .= '<a href="'.get_permalink().'" title="'.$title.'">'.$title.'</a>&nbsp;&nbsp;-&nbsp;&nbsp;';
 	endwhile;
	$tickerFile = "newsTicker.txt";
	$fh = fopen($tickerFile, 'a');
	fwrite($fh,$tickerContent);
	fclose($fh);
}
?>

    I’ll work on a generic version of this plugin and offer it with a fully customisable interface.
