WordPress -> XML -> Flash

saw some old topics about, but apparently no solutions, so here are mines

i use this for feeding swf’s with xml generated by wordpress
so, instead of giving myfile.xml as reference to flash, i give myfile.xml.php

example 1, config.xml.php, simple custom field query of post with id 101

<?php
require_once "../wp-load.php";
$phone = get_post_meta(101, 'phone', true);
$email = get_post_meta(101, 'email', true);
$xml = <<<EOT
<data>
	<settings>
		<phone>{$phone}</phone>
		<email>{$email}</email>
	</settings>
</data>
EOT;
echo $xml;
?>

example 2, gallery.xml.php?id=POST_ID, full gallery of a post, got to feed the id in the url

<?php
	require_once "../wp-load.php";
	$id = intval($_GET['id']);

	function GetGallery($idi){
		$idi = intval($idi);
		$img = array();
		$results = get_children( array(
			'post_parent' => $idi,
			'post_status' => 'inherit',
			'post_type' => 'attachment',
			'post_mime_type' => 'image',
			'order' => 'ASC',
			'orderby' => 'menu_order') );
		foreach ( $results as $imagem )
		{
			$pic=wp_get_attachment_image_src( $imagem->ID, 'medium' );
			$title = $imagem->post_title;
			$txt = $imagem->post_content;
			$img[] = array('href' => $pic[0], 'title' => $title, 'txt' => $txt);
		}
		return $img;
	}

	$GAL = GetGallery($id);

	$xml = '<?xml version="1.0" encoding="UTF-8"?>' . "\n\n";
	$xml .= '<gallery>' . "\n\n";

	$xml .= '<options>' . "\n\n";
	$xml .= '    <name>ONE OF MANY</name>' . "\n\n";
	$xml .= '</options>' . "\n\n";

	$xml .= '<pictures>' . "\n\n";
	foreach($GAL as $jpg) {
		$xml .= '    <pic>' . "\n";
		$xml .= '        <bigimage>' . $jpg['href'] . '</bigimage>' ."\n";
		$xml .= '        <info title="'. $jpg['title'] .'" desc="'. $jpg['txt'] .'" />' . "\n";
		$xml .= '    </pic>' . "\n\n";
	}
	$xml .= '</pictures>' . "\n\n";
	$xml .= '</gallery>';

	echo $xml;
?>

important:
– path to wp-load.php, in these examples the files are inside /wp-content
– attention to the use of single and double quotes

i used 2 techniques to echo the xml, the first example uses one i discovered recently

i think the second example opens the door to very complex xml structures
you can try it saving the code as gallery.xml.php inside your wp-content, and then go to the address: https://yousite.com/wp-content/gallery.xml.php?id=ID-OF-DESIRED-POST

good luck
