Add Template File to a Post Using Shortcode

// read file
function include_template_file ($template_path=null) {
	if($template_path == null)
		return '';
    load_template( get_template_directory() .'/'. $template_path );
	$content = ob_get_contents();
	return $content;
// shortcode code
function include_template_shortcode($atts, $content=''){
	 extract( shortcode_atts( array(
	      'path' => null
     ), $atts ) );
	return include_template_file($path);
add_shortcode( 'include_template', 'include_template_shortcode' );
// Example:
// [include_template path='assets/my-file.php']

Converting Date to Number and then back to Date

I recently implemented a delete file solution in witch I wanted to preserve the file in a trash folder, so I could eventually restore the file. Instead of deleting the file I renamed it and move it to the trash folder. Since a file with the same name could be re-created and then re-deleted, I wanted to make sure that I can preserve all the different versions of the file and and allow restoring any of the previously deleted version.

The solution that I implemented required to add a suffix to the name of the file using the current date and time as a number. Later on I can present a list of the files in the trash folder and convert the date-suffix back to the date and time when the file was deleted, allowing users to choose which version they want to restore.

$file_name = 'my-image.png';
$date = date('Y/m/d H:i:s');
$date_as_number = strtotime($date);
$new_file_name = $file_name . '.' . $date_as_number;
echo $file_name ."\n";      // prints: "my-image.png"
echo $date ."\n";           // prints: "2012/11/28 23:51:21"
echo $date_as_number ."\n"; // prints: "1354168281"
echo $new_file_name ."\n";  // prints: "my-image.png.1354168281"
// parse the file name and show deleted date
$deleted_date_as_number = array_pop(explode('.', $new_file_name));
$deleted_date_as_string = date('l dS \o\f F Y h:i:s A', $deleted_date_as_number);
$original_file_name = implode('.', array_slice(explode('.', $new_file_name), 0, -1) );
echo $deleted_date_as_number ."\n"; // prints: "1354168281"
echo $deleted_date_as_string ."\n"; // prints: "Wednesday 28th of November 2012 11:57:37 PM"
echo $original_file_name ."\n";     // prints: "my-image.png"
echo "Do you want to restore the file \"". implode('.', $original_file_name) . "\" deleted on \n$deleted_date_as_string?";
// prints: Do you want to restores the file "my-image.png" deleted on 
// Wednesday 28th of November 2012 11:57:37 PM?

Get individual value from a Post or Page

 * for $value you can use any post field (i.e. post_description, post_title, etc.
function get_post_value($id_or_name, $value='post_title') {
	global $wpdb;
	if(is_int($id_or_name)) {
		$field = 'ID';
	} else {
		$field = 'post_name';
	$value = $wpdb->get_var("SELECT $value FROM $wpdb->posts WHERE $field = '".$post_name."'");
	return $value;

Get Post or Page by Name

$post_title = 'my-post-name';
$post = get_page_by_title($post_title, OBJECT);
