Create a condition between SAVE and SAVE&PUBLISH - publish

Question

I seem to get a tangled mind these past few days with my project. I'm trying to build a custom cms and I am up to the point of creating posts for website pages.
I have two(2) buttons -> 'SAVE' and 'SAVE & PUBLISH' The SAVE button will submit my form fields to the database but not putting number 1 in the publish field so it wouldn't be processed as published while the SAVE&PUBLISH will do the same but will put number 1 to the publish field so it will be processed as published.
How do I build a condition with this without probably messing up my code? I know this comes with a little tweaking. Please see my current code.
// CHECK IF THE FORM WAS SUBMITTED
if( isset( $_POST['submit'] ) ){
$title = $_POST['title'];
$editor_data = $_POST[ 'editor1' ];
$format = $_POST[ 'format' ];
$page = $_POST['page'];
//IF FORM WAS SUBMITTED, CHECK IF THERE ARE ERRORS
if(empty($title) === true){
$errors[] = "You forgot to add a Title";
}
if(empty($editor_data) === true){
$errors[] = "You forgot to add a Content";
}
if(empty($format) === true){
$errors[] = "Please choose a title format";
}
if(empty($page) === true){
$errors[] = "Please choose a Page";
}
//IF THE ERROR ARRAY IS EMPTY THEN PROCESS THE FORM
if (empty($errors) === true){
switch ($format)
{
case "1":
$post_title = "<h1>".$title."</h1>";
break;
case "2":
$post_title = "<h2>".$title."</h2>";
break;
case "3":
$post_title = "<h3>".$title."</h3>";
break;
case "4":
$post_title = "<h4>".$title."</h4>";
break;
case "5":
$post_title = "<h5>".$title."</h5>";
break;
case "6":
$post_title = "<h6>".$title."</h6>";
break;
default:
$post_title = $title;
}//>end of switch
//current time zone
date_default_timezone_set('Asia/Manila');
$date = date('Y-m-d');
$date_time = date('Y-m-d H:i:s');
//INSERT VALUES FROM FORM TO THE DATABASE TABLE
mysql_query("INSERT INTO posts (`post_title`, `post_content`, `post_page`, `date_posted`) VALUES('$post_title', '$editor_data', '$page', '$date_time')");
// IF ERROR ARRAY IS NOT EMPTY, OUTPUT ERRORS!
} else if(empty($errors) === false){
//output errors
echo output_errors($errors);
}//> end of else if errors
}//>end of isset submit

Solved my own question. My only concern now is how do I make this block of code shorter. Is there a workaround for this?
// CHECK IF THE FORM WAS SUBMITTED AS SAVED
if( isset( $_POST['save'] ) ){
$title = $_POST['title'];
$editor_data = $_POST[ 'editor1' ];
$format = $_POST[ 'format' ];
$page = $_POST['page'];
//IF FORM WAS SUBMITTED, CHECK IF THERE ARE ERRORS
if(empty($title) === true){
$errors[] = "You forgot to add a Title";
}
if(empty($editor_data) === true){
$errors[] = "You forgot to add a Content";
}
if(empty($format) === true){
$errors[] = "Please choose a title format";
}
if(empty($page) === true){
$errors[] = "Please choose a Page";
}
//IF THE ERROR ARRAY IS EMPTY THEN PROCESS THE FORM
if (empty($errors) === true){
switch ($format)
