right i have made a sign script but the only thing that does work is the email it don't insert into the database for some reson here is my script

<?php 
// Connects to your Database 
mysql_connect("localhost", "**", "***") or die(mysql_error()); 
mysql_select_db("web160-admin-21") or die(mysql_error()); 

//This code runs if the form has been submitted
if (isset($_POST['submit'])) { 

//This makes sure they did not leave any fields blank
if (!$_POST['username'] | !$_POST['pass'] | !$_POST['pass2']) {
die('You did not complete all of the required fields');
}

// checks if the username is in use
if (!get_magic_quotes_gpc()) {
$_POST['username'] = addslashes($_POST['username']);
}
$usercheck = $_POST['username'];
$check = mysql_query("SELECT username FROM users WHERE username = '$usercheck'") 
or die(mysql_error());
$check2 = mysql_num_rows($check);

//if the name exists it gives an error
if ($check2 != 0) {
die('Sorry, the username '.$_POST['username'].' is already in use.');
}

// this makes sure both passwords entered match
if ($_POST['pass'] != $_POST['pass2']) {
die('Your passwords did not match. ');
}

// here we encrypt the password and add slashes if needed
$_POST['pass'] = md5($_POST['pass']);
if (!get_magic_quotes_gpc()) {
$_POST['pass'] = addslashes($_POST['pass']);
$_POST['username'] = addslashes($_POST['username']);
}

// now we insert it into the database
$insert = "INSERT INTO users (username, password, realname, email)
VALUES ('".$_POST['username']."', '".$_POST['pass']."', '".$_POST['realname']."', '".$_POST['email']."')";
$add_member = mysql_query($insert);
?>

Thank you for using the code tags.

PHP is case sensitive in almost every circumstance.

Your field name is "Email" but you are trying to use $_POST['email'] which does not match.

Danny620 · December 12, 2008

thanks for that but how would i go about making a foum saying about me to submint to the database

Brian W · December 12, 2008

umm, what?

foum? (forum? form?)

i'm guessing i could translate to "a form that asks about me that I submit to the database".

You would create an HTML form with the fields you need, and then use a the SQL syntax for INSERT to add a new about me section. To update, you'd use a similar technique except that you'd use the SQL syntax for UPDATE.

The code u posted oh so nicely withing code tags below looks like you got a template from some one. Do you understand what each step does? If not, you need to get looking at more tutorials or hope you can get another template from online for what you want to do.

waynew · December 13, 2008

Show us your database structure.

Danny620 · December 13, 2008

Right i have mananaged to do that about me i was well heappy i fugured it out for my self i looked at the other code and tryed and do it myself also yes this is a temple but i have added email realname and about me to it also changed the form can you have a scan thought this code to make sure its safe and good to user nothing can change about it thanks very much so far

}

See that piece of code there? It's defunct. Or will be once PHP 6 comes out.

Use this instead:

// checks if the username is in use
if (function_exists('mysql_real_escape_string')) {
$_POST['username'] = mysql_real_escape_string($_POST['username']);
}
else{
$_POST['username'] = mysql_escape_string($_POST['username']);
}

Danny620 · December 13, 2008

ok thanks whens php 6 set to come out

waynew · December 13, 2008

ok thanks whens php 6 set to come out

Heh, your guess is as good as mine at this stage. But at least you wont have to worry about it when it does.

premiso · December 13, 2008

ok thanks whens php 6 set to come out

Well PHP 5 is just starting to become standard and most production servers, I would say when PHP5.4.x is release they will have a non-beta PHP 6, but you will never know as it is up to the developers to decide when it is ready.

waynew · December 13, 2008

Whoa. Sorry, was looking through your code and realised that the same kind of thing is going on throughout it.

Use:

<?php 
// Connects to your Database 
mysql_connect("localhost", "***", "***") or die(mysql_error()); 
mysql_select_db("***") or die(mysql_error()); 

//This code runs if the form has been submitted
if (isset($_POST['submit'])) { 

//This makes sure they did not leave any fields blank
if (!$_POST['username'] | !$_POST['pass'] | !$_POST['pass2'] | !$_POST['realname'] | !$_POST['email']) {
die('You did not complete all of the required fields');
}

// checks if the username is in use
$_POST['username'] = mysql_real_escape_string($_POST['username']);
$usercheck = $_POST['username'];
$check = mysql_query("SELECT username FROM users WHERE username = '$usercheck'") 
or die(mysql_error());
$check2 = mysql_num_rows($check);

//if the name exists it gives an error
if ($check2 != 0) {
die('Sorry, the username '.$_POST['username'].' is already in use.');
}

// checks if the email is in use
$_POST['email'] = mysql_real_escape_string($_POST['email']);
$usercheck = $_POST['email'];
$check = mysql_query("SELECT username FROM users WHERE email = '$usercheck'") 
or die(mysql_error());
$check2 = mysql_num_rows($check);

//if the name exists it gives an error
if ($check2 != 0) {
die('Sorry, the email '.$_POST['email'].' is already in use.
<a href="signup.php"> Click here to go back</a>');
}

// this makes sure both passwords entered match
if ($_POST['pass'] != $_POST['pass2']) {
die('Your passwords did not match. ');
}

// here we encrypt the password and add slashes if needed
$_POST['pass'] = md5($_POST['pass']);
$_POST['pass'] = mysql_real_escape_string($_POST['pass']);
$_POST['username'] = mysql_real_escape_string($_POST['username']);
$_POST['aboutyou'] = mysql_real_escape_string($_POST['aboutyou']);
$_POST['realname'] = mysql_real_escape_string($_POST['realname']);


// now we insert it into the database
$insert = "INSERT INTO users (username, password, realname, email, aboutyou)
VALUES ('".$_POST['username']."', '".$_POST['pass']."', '".$_POST['realname']."', '".$_POST['email']."', '".$_POST['aboutyou']."')";
$add_member = mysql_query($insert);

This line here....

if (!$_POST['username'] | !$_POST['pass'] | !$_POST['pass2'] | !$_POST['realname'] | !$_POST['email']) {

needs to be....

if (!$_POST['username'] || !$_POST['pass'] || !$_POST['pass2'] || !$_POST['realname'] || !$_POST['email']) {

Danny620 · December 13, 2008

if (!$_POST['username'] || !$_POST['pass'] || !$_POST['pass2'] || !$_POST['realname'] || !$_POST['email']) {

why does that need to be changed

Because you need a logical or || not a bitwise or |

$mysql = mysqli_connect('localhost', 'username', 'password', 'database') or die('An error has occured.');

Is your username = username?

Is your password = password?

Is your database called database?

Danny620 · December 15, 2008

wtf man well not its not but i am not going to but it my real detiels in now am i

Brian W · December 15, 2008

not trying to infiltrate, just making sure your knew you had to set those. use **** or something and that will let us know you are just censoring. "usename" makes it look like you neglected to fix your template to what you need it to be.

Your "mate" who wrote that isn't very helpful. It is like handing a 2 year old legos instead of megablocks (don't mean that offensively). Its not helpful if you don't understand what it does exactly and you should start with a less complex version of that so that you know what each step is doing without having those comments.

But, basically, that is exactly what that script does, just uses some syntax that isn't exactly novice.
