Question

The $post->ID is not correct on some pages

Asked by: gagnonconsulting

I have added the following code to the beginning of my header.php file so I can redirect the page if the 'direct_jump' metapost data value is set. That part works (with the print and header statements commented appropriatly), but I have found that often the $post->ID value is incorrect, and it will jump to the redirect page when it is not supposed to. It looks like the $post array is not getting cleared or set correctly when I go to some pages, including the home page and the main category page of the posts. Any ideas on how to proceed?

$thisPost = $post -> ID;
$gotoURL = '';
$gotoURL = get_post_meta($thisPost, 'direct_jump', true);
if ($gotoURL != '') { 
print ("thisPost = $thisPost, ");
print ("header('Location: $gotoURL');");
//header('Location: '.$gotoURL);
}

Does your home page show recent posts?

If it does, try changing your code to the below. The post id gets confused on category, archive, or home if it's set to show a list of posts.

if (is_single()) {
	$thisPost = $post -> ID;
	$gotoURL = '';
	$gotoURL = get_post_meta($thisPost, 'direct_jump', true);
	if ($gotoURL != '') { 
	print ("thisPost = $thisPost, ");
	print ("header('Location: $gotoURL');");
	//header('Location: '.$gotoURL);
	}
}

Close, but the page is only single if it is on the post page, which is the page that I am trying to avoid going to in the first place. Basically, I need it to work on a page that has multiple posts showing such as the home page and the ones in the weburl/archives/catagory/... pages, not just on the weburl/archives/nnn pages.

 

by: DzynitPosted on 2009-09-04 at 13:41:16ID: 25263173

To allow the code to run on all pages except the single post pages, change line 1 to this:

if (!is_single()) {


The pages which list multiple posts will set the post id call to the first post listed on the page. Which post are you actually wanting to get the id of when you are on a page such as category?

Again, thanks, but that does not help my issue. The problem is that when I run it, which needs to be done on all pages, I need the correct $post-ID so I can look up and see if there is a specific postmeta tag set for the page the I am about to display. If there is, I want to jump to a URL defined in the postmeta tag for that page. Since I am getting erroneous post-ID values, this is the problem. So the solution to this problem would be to know how to get the correct post->ID for any and all pages that I am about to view.

Give this a try:
$thisPost = url_to_postid($_SERVER['REQUEST_URI']);

Hi
The site is http://www.hbama.com
That said, this past week, I upgraded to Wordpress 2.8.4, and have the code as attached at the very top of the header.php file in my custom theme directory. I have not added any conditionals around it, but now it seems to work properly (the two posts on my site that have the 'direct_jump' url set are the "For Consumers/***Find and Hire..." and "For Members/*** Signup for..." These now both jump directly to their respective pages, not the category archive list page. Not sure if the fix is due to the version update or something else that I am not understanding.

<?php
// direct_jump
// Added by Gagnon Consulting, Inc.
// checks to see if the meta_data field called 'direct_jump' is populated, 
// and if it is, redirects immediately to the url string that is in the direct_jump field
        $thisPost = $post -> ID;
        $gotoURL = '';
        $gotoURL = get_post_meta($thisPost, 'direct_jump', true);
        if ($gotoURL != '') { 
        	//print ("thisPost = $thisPost, ");
        	//print ("header('Location: $gotoURL');");
        	header('Location: '.$gotoURL);
        }
// end of direct_jump
?>
