Unable to retrieve posts in custom loop

    Hi,

    I’m trying to make a utility for automating some of my post maintenance tasks. And I put in the basic loop structure for looping through all my posts. But, when I try to get the content of a post during an iteration, I never get anything. I’m not using the usual statements for displaying my posts because I’m not interested in displaying anything. I just want to use the data. So, for example, instead of using the_post, I use get_post(PostID), and instead of the_content, I use get_the_content(), and so on.
    The results I get, are always blank, except for the PostID. The get_the_ID() function always returns 888 for every iteration eventhough I give 1,2,3.. for my PostID parameter in get_post().
    Apparently, I’m not reaching the area where my posts are.
    Below, is a beginning excerpt of my code. (Using a for loop now instead of a while loop to limit my iterations just to get something to work first.)

    <?php if (have_posts()) { for ($i=1; $i <=5; $i++) { get_post($i); ?>

     <?php 

	// If not done already, get the author name of the YT post on
        // YT itself, add author name to post content, and add
        // "author" to post tags.

	$content_string = get_the_content();
	$postID = get_the_ID();
	$post_tags_array = wp_get_post_tags($postID);
	$auth_tag_string = "author";

        ....
        ....
        .... and so on					

     } //for
     } //if

     ?>

    Thank you for any help.

  • The get_post() function requires a post ID as a parameter. You are passing in an integer that does not match any posts. Stick to the usual if (have_posts()): while (have_posts()): the_post(); construct.

    Thank you for the response. I brought it back to the original way. But, still, I’m not getting any posts. Is there some preliminary steps I need to take in order to establish communication with the dataase? Here’s the revised code:

    <?php if (have_posts()) { while (have_posts()) { the_post(); ?>

   <?php 

	// If not done already, get the author name of the YT post on
        // YT itself, add author name to post content, and add
        // "author" to post tags.

	$content_string = get_the_content();
	$postID = get_the_ID();
	$post_tags_array = wp_get_post_tags($postID);
	$auth_tag_string = "author";

        ....
        ....
        .... and so on					

     } //while
     } //if

     ?>

    Thanks again for any further help.

    Sorry for not mentioning this in the beginning. The method I’m using for invoking my PHP code is by making it the template file for a private page I added to my blog. When I access that page, the php code starts running. Also, the debugger I’m using is FirePHP (on my Firefox browser).

    If you posted the complete code above, you probably need a query_posts() call before the if have_posts(), something like this:

    <?php query_posts('posts_per_page=-1'); ?>
<?php if (have_posts()) { while (have_posts()) { the_post(); ?>

    vtxyzzy,
    Your a genius! It’s now accessing my posts and getting me all the data I’m looking for.
    Thank you so much for your help.
    Take care.
