Input data Guestbook PHP - php

Question

Im trying to create a guestbook with mysql database. I have no trouble display the sql data on my form.
But when im trying to input data my send button dosent work. I think the problem is in this code, but I cant find it. and have done the tutorial a couple of times.
I dont have any error messages. But this is some of the code.
thanks
<?php
if(isset($_GET['page'])){
echo "
<form action='guest_process.php' method='post'>
<p>Name: <input type='text' name='name'> </p>
<p>Email: <input type='text' name='email'> </p>
<p>Comment: </p>
<p><textarea name='comment'></textarea></p>
<hr />
<p><input type='button' name='submit' value='Post Entry'></p>
</form>
";
}else{
$connect = mysql_connect('localhost','root','') or die ('Couldnt connet');
$db = mysql_select_db('guestbook');
$query = mysql_query('select * from guestbook order by id desc');
$num_rows = mysql_num_rows($query);
if($num_rows > 0){
//display entries
while($row = mysql_fetch_assoc($query)){
echo "
<p>
<b>Name: </b>".$row['name']."
</p>
<p>
<b>Email: </b>".$row['email']."
</p>
<p>
<b>Comment: </b>".$row['comment']."
</p>
<p>
<b>Date: </b>".$row['date']." | Time: ".$row['time']."
</p>
<hr />
";
}
} else{
echo 'no entries in database';
}
}
?>
The guestbook is seperated in two php files.
This is the other page the guest_process.php
<?php
if($_post['submit']){
$connect = mysql_connect('localhost','root','') or die ('Couldnt connet');
$db = mysql_select_db('guestbook');
$name = strip_tags($_POST['name']);
$email = strip_tags($_POST['email']);
$comment = n12br($_POST['comment']);
$date = date('Y-m-d');
$time = date('H:i:s');
$query = mysql_query("insert into guestbook values('','$name','$email','$comment','$date','$time')");
header('Location: index.php');
}else {
header ('Location: index.php');
}
?>

Answer 1

use <input type="submit" value="Post Entry"> instead of <input type=button>

Answer 2

this is not good:
<input type =button name='submit' value='Post Entry'>
it should be:
<input type="submit" name="submit" value="Post Entry">

Answer 3

The problem is that there is no code to put anything in a database.
First you need to actually post something. You might think that this line does this, but it doesn't:
<input type =button name='submit' value='Post Entry'>
Apart from the fact you need " around the type, a "button" isn't actually something that does submitting. You'll need client-side code for that. You could better change it to
<input type="button" name='submit' value='Post Entry'>
You won'nt be there though. Now you need to take the info from the $_POST variable (try var_dump($_POST) to see what's in there), and put it in your database. You can find the appropriate commands for SQL and the php-mysql connection in your tutorial probably
