    This plugin is used to store pairs of data with a post. Everything gets saves just find, but randomly, data will vanish.

    Help! I have no idea why this is happening.

    function post_head_menus() {
    	if (function_exists('add_meta_box')) {
    		add_meta_box('post_head_box','Energy System Details','post_head_meta','energy-systems');
    	}
    }
    
    function post_head_meta() {
    	global $wpdb, $post_ID;
    	$files = post_head_get_files($post_ID);
    	?>
    
    	<table>
    		<thead>
    			<tr>
    				<th width="50%">BPM</th>
    				<th width="50%">Duration</th>
    			</tr>
    		</thead>
    		<tbody>
    		<?php
    $i = 0;
    if ($files && $post_ID) {
    foreach ((array)$files as $file) { ?>
    			<tr id="post-head-<?php echo $i; ?>">
    				<td><input type="text" name="post-head[<?php echo $i; ?>][bpm]" value="<?php echo $file['bpm']; ?>" /></td>
    				<td><input type="text" name="post-head[<?php echo $i; ?>][duration]" value="<?php echo $file['duration']; ?>" /></td>
    				<td><a href="#" class="button" onclick="post_head_remove(<?php echo $i; ?>); return false;">X</a></td>
    			</tr>
    <?php $i++;
    }; }; ?>
    			<tr id="post-head-<?php echo $i; ?>">
    				<td><input type="text" name="post-head[<?php echo $i; ?>][bpm]" /></td>
    				<td><input type="text" name="post-head[<?php echo $i; ?>][duration]" /></td>
    				<td><a href="#" class="button" onclick="post_head_remove(<?php echo $i; ?>); return false;">X</a></td>
    			</tr>
    		</tbody>
    	</table>
    	<p align="right" style="padding:10px 0 5px; margin:0;"><a href="#" class="button" id="add-post-head-file">Add</a></p>
    	<?php
    
    }
    
    function post_head_get_files($ID) {
    	$data = unserialize(get_option("post-head-files"));
    	return $data[$ID];
    }
    
    function post_head_delete() {
    	delete_option('post-head-files');
    }
    
    function post_head_submit($post_ID) {
    
    	global $wpdb;
    
    	if ( defined('DOING_AUTOSAVE') && DOING_AUTOSAVE ) {
    	    return $post_id;
    	}
    
    	// Check permissions
    	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;
    	}
    
    	foreach((array)$_POST['post-head'] as $file) {
    		if ($file['bpm'] != "" && $file['duration'] != "") $t[] = $file;
    		$data[$post_ID] = $t;
    	}
    
    	update_option('post-head-files', serialize($data));
    }
    
    function post_head_admin_head() {
    	echo '<link type="text/css" rel="stylesheet" media="all" href="'.plugins_url('energy-systems-module/admin.css').'" />'."\n";
    	echo '<script type="text/javascript" src="'.plugins_url('energy-systems-module/post-header.js').'"></script>'."\n";
    }
    
    add_action('admin_head', 'post_head_admin_head');
    add_action('admin_menu', 'post_head_menus');
    add_action('save_post', 'post_head_submit');
