I have this code, that picks article content from my word press db then outputs it onto a table, using a loop. once a user select the articles they like they submit the selection to my next page call it displaypage to display the selected articles.
the selection page code looks like this.
<?php /*
Template Name: News Selector Template
*/
//Pull the data
$posts = $wpdb->get_results
("
SELECT
p1.*,
wm2.meta_value
FROM
mp_posts p1
LEFT JOIN
mp_postmeta wm1
ON (
wm1.post_id = p1.id
AND wm1.meta_value IS NOT NULL
AND wm1.meta_key = '_thumbnail_id'
)
LEFT JOIN
mp_postmeta wm2
ON (
wm1.meta_value = wm2.post_id
AND wm2.meta_key = '_wp_attached_file'
AND wm2.meta_value IS NOT NULL
)
WHERE
p1.post_status='publish'
AND p1.post_type='post'
ORDER BY
p1.post_date DESC LIMIT 0,30
");
?>

Iv used implode to collect the array variables of all selected articles via a check box option.
on my display page i wrote this simple code to see the output of the array.
<?php /*
Template Name: Newsletter Template
*/
$posts = explode(",", $_POST['metas']);
?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
</head>
<body>
<?php echo $posts[0]->guid ?>
<?php echo $posts[0]->meta_value ?>
<?php echo $posts[0]->post_title ?>
<?php echo $posts[0]->post_excerpt ?>
</body>
</html>
Now when i submit the selected articles from the first page i'm supposed to be able to access the various array elements in my display page, but that's not the case. i get the ERROR
Warning: implode(): Invalid arguments passed in /home/sampled/public_html/brands/sample/wp-content/themes/newsample/page-newsselector.php on line 164
i don't know where i went wrong with my implementation.
HELP PLEASE
