wp_list_pages Classes

Ok that is strange. On my server it is working. Let’s do some testing.
in stead of the code I gave you paste this code:

<?php
	$my_pages = get_pages('meta_key=class&meta_value=print');
	echo '<pre>';
        print_r($my_pages);
        echo '</pre>';
?>

If you don’t see a big array with your pages, get_pages is not working or you don’t have a page with a custom field with key = class and value = print.
If you don’t see a big array paste this code:

<?php
	$my_pages = get_pages();
	echo '<pre>';
        print_r($my_pages);
        echo '</pre>';
?>

If you don’t see a big array with all your pages get_pages is not working.

If you go to a page (with the custom field) in your dashboard does it look like this.

thank you again for your help kees.

I got an array from that second code but none from the first one so I must have done the custom field wrong. Here’s a screenshot of the custom field, where am I going wrong?

aha I didn’t see your latest post before I posted but they look the same to me?

ok get_pages is working. They look the same, yes. Now try this:

<?php
	$my_pages = get_pages('meta_key=class');
	echo '<pre>';
        print_r($my_pages);
        echo '</pre>';
?>

still no results, just says

Array

did you paste “class” and “print” in the custom field. sometimes you paste in a space (class[space] or [space]print) and it doesn’t work. We keep on testing.
make a new custum field. name: myclass, value: print. (dont paste or be sure of no spaces)
try this one again:

<?php
	$my_pages = get_pages('meta_key=myclass&meta_value=print');
	echo '<pre>';
        print_r($my_pages);
        echo '</pre>';
?>

otherwise I don’t know what is causing this. (keeps on thinking)

hmmm still getting nothing, how annoying. does it matter if the pages are a child of another page? also does it matter if there are other custom fields?

We could test for that to. (it is probably the child page that stumps us) but first if you know the page ID of a page with the custom field (myclass)do this:

<?php
        $key_1_value = get_post_meta(65, 'myclass', true);
        echo 'myclass value =' . $key_1_value ;
?>

substitute 65 for your ID

myclass value =print

is what i get

That’s good. I got it. It was the child category that did it.
now try:

<?php
	$my_pages = get_pages('child_of=65&meta_key=myclass&meta_value=print');
	echo '<pre>';
        print_r($my_pages);
        echo '</pre>';
?>

substitute 65 for the parent ID where the child page with custom field (myclass) belongs to. And see if you get an array with all the pages with meta_key =myclass.

(posted twice) sorry

bingo that worked ??

Ok I will make the function for yor 3 classes now

Ok put this in your functions.php

function get_my_pages($id, $class='', $value='') {
	if($class !='' && $value != '' ) {
		$parentID = ($id == '') ? '' : '&child_of='.$id;
		$my_pages = get_pages('meta_key=' . $class . '&meta_value=' . $value . $parentID);
		$html= '';
                if(!empty($my_pages)){
		$html .= '<ul>';
                  foreach ($my_pages as $pagg) {
  	    	  $html .=  '<li class="' . $pagg->meta_value . '"><a href="' . get_page_link($pagg->ID) . '">';
  	    	  $html .=  $pagg->post_title . '</a></li>';
                  }
               $html .= '</ul>';
               return $html;
               }
        }
}

You can call this function in your template with:
<?php echo get_my_pages(65, 'myclass', 'print'); ?>
The two second values, “myclass” and “print” stand for the meta_key and the meta_value. you have to fill these in. The first value (65) stands for the parent page ID. You don’t have to fill this in, so you can use this function on parent pages as well. call the function like so: <?php echo get_my_pages('', 'myclass', 'print'); ?>
The li gets its class from the meta_value (third value in the function)
