get_pages in functions.php problem

Just a guess, but shouldn’t that bit of code be surrounded by a function structure?

function my_page_array($arg) {

your code

}

Not sure what $parent is…

Also not sure you need setup_postdata there, just use
$parentid=$trip->post_parent;

thanks for that you were right i managed to figure it out before you posted it.

ive got another problem though i tried using your code but it didnt fix it.
basically i cant get the data from the post so i cant get the parentid for example.
here is my code:

$triplistarray = array();
$tripparent = 2;
$args=array(
  'child_of' => $tripparent,
);
$gettrips = get_pages($args);
if (@count($gettrips)) {
  foreach($gettrips as $post) {
	$parentid=$trip->post_parent;
	if ($post->post_parent !== $parentid ) {
		 array_push($triplistarray,$post->ID);
	}
  } // foreach($pages
} // if ($pages

so at the moment the if ($post->post_parent !== $parentid ) { doesnt work

Start over….what’s the goal here? What is it you are trying to accomplish with that code?

essentially i am creating a custom write panel that has a dropdown in it with a list of the grandchildren pages that you helped me with before. the idea is that someone can submit a post in the report category and can then assign the report to a trip using the id into a custom field. the above code is being used to get the list of grandchildren from the top parent (the grandparent). however since this is now in the function file and inside a function it isn’t getting the post data such as the parent id and title.

here is all the code:

$new_meta_boxes =
array(
"triplist" => array(
"type" => "select",
"std" => "",
"name" => "asigntrip",
"title" => "Assign Trip",
"description" => "")
); 

function new_meta_boxes() {
	global $post, $new_meta_boxes;

$triplistarray = array();
$tripparent = 2;
$args=array(
  'child_of' => $tripparent,
);
$gettrips = get_pages($args);
if (@count($gettrips)) {
  foreach($gettrips as $post) {
	$parentid=$trip->post_parent;
	if ($trip->ID !== $parentid ) {
		 array_push($triplistarray,$post->ID);
	}
  } // foreach($pages
} // if ($pages

	foreach($new_meta_boxes as $meta_box) {

		echo'<input type="hidden" name="'.$meta_box['name'].'_noncename" id="'.$meta_box['name'].'_noncename" value="'.wp_create_nonce( plugin_basename(__FILE__) ).'" />';

		echo'<h2>'.$meta_box['title'].'</h2>';

		if( $meta_box['type'] == "text" ) { 

			$meta_box_value = get_post_meta($post->ID, $meta_box['name'].'_value', true);

			if($meta_box_value == "")
				$meta_box_value = $meta_box['std'];

			echo'<input type="text" name="'.$meta_box['name'].'_value" value="'.$meta_box_value.'" size="55" />';

		} elseif ( $meta_box['type'] == "select" ) {

			echo'<select name="'.$meta_box['name'].'_value">';
			echo'<option value="">select trip</option>';
			foreach ($triplistarray as $option) {

				if ( get_post_meta($post->ID, $meta_box['name'].'_value', true) == $option ) {
					$sel =  ' selected="selected"';
				} elseif ( $option == $meta_box['std'] ) {
					$sel = ' selected="selected"';
				}
				echo'<option value="'.$option.'"'. $sel .'>'. $post->post_title .'</option>';

			}

			echo'</select>';

		}

		echo'<p><label for="'.$meta_box['name'].'_value">'.$meta_box['description'].'</label></p>';
	}
}

function create_meta_box() {
global $theme_name;
if (function_exists('add_meta_box') ) {
add_meta_box( 'new-meta-
boxes', 'More Info', 'new_meta_boxes', 'post', 'normal', 'high' );
}
}

function save_postdata( $post_id ) {
global $post, $new_meta_boxes;
foreach($new_meta_boxes as $meta_box) {  

// Verify
if ( !wp_verify_nonce( $_POST[$meta_box['name'].'_noncename'], plugin_basename(__FILE__) )) {
return $post_id;
}  

if ( 'page' == $_POST['post_type'] ) {
if ( !current_user_can( 'edit_page', $post_id ))
return $post_id;
} else {
if ( !current_user_can( 'edit_post', $post_id ))
return $post_id;
}  

$data = $_POST[$meta_box['name'].'_value'];  

if(get_post_meta($post_id, $meta_box['name'].'_value') == "")
add_post_meta($post_id, $meta_box['name'].'_value', $data, true);
elseif($data != get_post_meta($post_id, $meta_box['name'].'_value', true))
update_post_meta($post_id, $meta_box['name'].'_value', $data);
elseif($data == "")
delete_post_meta($post_id, $meta_box['name'].'_value', get_post_meta($post_id, $meta_box['name'].'_value', true));
}
}

add_action('admin_menu', 'create_meta_box');
add_action('save_post', 'save_postdata');

i really appreciate your help

Sorry, that’s beyond me…maybe someone else can jump in with an idea.

the only problem i am having is getting the data from the post in this:

$triplistarray = array();
$tripparent = 2;
$args=array(
  'child_of' => $tripparent,
);
$gettrips = get_pages($args);
if (@count($gettrips)) {
  foreach($gettrips as $post) {
	$parentid=$trip->post_parent;
	if ($trip->ID !== $parentid ) {
		 array_push($triplistarray,$post->ID);
	}
  } // foreach($pages
} // if ($pages

i need to get the parent id as it goes through the loop and also the title to be used in the dropdown

this

foreach($gettrips as $post) {

should be

foreach($gettrips as $trip) {

and again this doesn’t seem right:

if ($trip->ID !== $parentid )

thanks so much for your help i got it work ??
using this:

$triplistarray = array();
$tripparent = 2;
$args=array(
  'child_of' => $tripparent,
);
$gettrips = get_pages($args);
if (@count($gettrips)) {
  foreach($gettrips as $trip) {
	if ($trip->post_parent != $tripparent ) {
		 array_push($triplistarray,$trip->ID);
	}
  } // foreach($pages
} // if ($pages

Whew. Good to hear you got it working. Congrats.
