How to add action tag to form?
I have a working php guestbook script. It's only 1 file. I tried to validate it and there is only one error:
Line 147, Column 36: required attribute "action" not specified
<form method="post" name="blogform">
Now the code is this and I'm sure I would need to break up the file to two so that I can create a file for the action tag but I just don't know how. Any help is much appreciated.
<?php
session_start();

if(isset($_POST['send'])) //checks if $_POST variable "is set"
if(isset($_SESSION["ellenorzo"]) && !empty($_SESSION["ellenorzo"]) && $_SESSION["ellenorzo"]==$_POST["code"]){
$name = trim($_POST['name']); //eliminating whitespaces
$email = trim($_POST['email']);
$message = addslashes( trim($_POST['message']));
$query = "INSERT INTO blog (name, email, message, date) " .
"VALUES ('$name', '$email', '$message', NOW())";
mysql_query($query) or die('Hey, something is wrong!' . mysql_error());
header('Location: ' . $_SERVER['REQUEST_URI']);

The action property specifies the link the form is sent to. If the form calls itself you can leave it blank:
<form action="" method="post" name="blogform">
The action tag tells the form where to submit the data. If it is left blank, it will attempt to submit the data to the current php page. If it's giving you trouble, perhaps you need to specify it and point it to the php page that generates the form.
In the code you provided, the bit of code which handles new inserts is at the top of this page, so you should set the action tag to be the name of the page.
By the way, you should ensure that your inputs are all cleaned; just using trim() before inserting them is asking for trouble. See here for more on this topic.
