i wanted to show a register script through echo like so<?php
session_start(); //allows session
include "config.php";
echo "<center>";
//checks if there trying to veriy there account
if(isset($_GET['verify'])) {
//gets the code and makes it safe
$code = addslashes($_GET['code']);
//gets the code from the database
$getcode=mysql_query("SELECT * FROM `verification` WHERE `code` = '$code'");
//counts the number of rows
$getcode = mysql_num_rows($getcode);
//if the ammount of rows is 0 the code does not exist
if($getcode == 0) {
echo "Invalid verification code!";
}
//or if the code does exist we will activiate there account
else{
//get the data from the database
$getcode=mysql_query("SELECT * FROM `verification` WHERE `code` = '$code'");
//fetchs the data from the db
$dat = mysql_fetch_array($getcode);
//sets the users user level to 2 which means they can now use there account
$update = mysql_query("UPDATE `members` SET `userlevel` = '2' WHERE `username` = '".$dat['username']."'") or die(mysql_error());
//deletes the code as there is no use of it now
$delete = mysql_query("DELETE FROM `verification` WHERE code = '$code'");
//says thanks and your account is ready for use
echo "Thank you, Your account has been verified.";
}
}else
//if we have posted the register for we will register this user
if(isset($_GET['register'])) {
//check to see if any fields were left blank

but i keep getting the error Parse error: syntax error, unexpected T_LNUMBER, expecting ',' or ';' in /home/runningp/public_html/register.php on line 96 but i dont dunerstand why as its part of the table :S

This is because on line 96, PHP encounters double quotes and thinks you're ending the echo.

The beauty of PHP is that you can mix PHP and HTML. It'll only display the HTML you put within the else.

Add a line above 86 and put ?> to end your PHP code. On line 86, take out echo " . Then, on lines 136 - 138, change:
</form>";
}
echo "<center>";
to
</form>
<?php } ?>
<center>

You are some where using double quotes and some where single quotes. Inside double quotes never use single quotes. Or write all HTML code out side the PHP tages.
This is a syntex error.
If you mis some where colon, quote, or if you use them in wrong way this type of error will occur. Clear the code again. make it clean. Errors will be wipe out.

ahhh yes that worked a treat...ty :)
