   Hi,I am new to programming.

   If you look at the following blog http://outdooractivitiesforkids.com/wordpress/?p=3 I get the following error

   Warning: Invalid argument supplied for foreach() in /home/a6228915/public_html/wordpress/wp-content/themes/positie_1/index.php on line 11

   and LINE 11 in index.php says:

   1. <?php get_header(); ?>
   2.
   3. <?php include(TEMPLATEPATH."/sidebar.php");?>
   4.
   5. <!-- begin content -->
   6. <div id="main">
   7. <?php if (have_posts()) : while (have_posts()) : the_post(); ?>
   8. <h1><?php the_title(); ?></h1>
   9.
   10. <? $postimg = get_post_meta($post->ID, "pre_image", false); ?>
   11. <? foreach($postimg as $image) {
   12. echo "<img class=\"fullimg\" src=\"".$image."\" />";
   13. } ?>
   .
   .
   .
   .
   .

   Please help how do I fix it. I want pictures in my blog.

   That would make me think <? $postimg = get_post_meta($post->ID, "pre_image", false); ?> returned nothing.

   add <?php print_r($postimg);?> after that to see what's returned.

   Also a good habit to use <?php rather than <?.

   Also, please note I've delete your other thread that mentions this same error.

   Are you saying insert the line you gave me between line 10 & 11... like this

   10. <? $postimg = get_post_meta($post->ID, "pre_image", false); ?>
   <?php print_r($postimg);?>
   11. <? foreach($postimg as $image) {

   Sorry for double posting ( in threads)

   Yes. I'm guessing that it will display NOTHING. You do have custom fields with 'pre_image', correct?
