The PHP Code

Here’s the code for the back-end page:

blog_process.php (excerpt)

<?php $editEntryId = $_POST["editEntryId"]; sleep(3); header("Content-Type: text/plain"); print "---\n"; print "status: success\n"; if ($editEntryId == "NewEntryTemp") { print "type: new\n"; print "id: " . time() . "\n"; } else { print "type: edit\n"; print "id: " . $editEntryId . "\n"; } print "..."; ?>

This fairly short chunk of PHP basically does the same thing whether you’re saving a new entry or editing an existing one.

In both cases, it returns the ID of the entry—either the ID for an edited entry that’s passed in from the browser, or a pretend ID that’s generated by the PHP time function to mimic the value that would be returned if this code were actually saving something to a database (like a MySQL auto_increment field, or a PostgreSQL serial). The main difference is whether the type is set to new or edit.
