 Posted: Fri Jul 11, 2008 8:37 am Post subject: [PHP]logging in |
 |
|
I'm trying to understand logging in. Because I was thinking how do I validate a correct log-in and I remember sessions. Just I don't totally get sessions. And even still, I'm not quite sure why that's important anyway, or how to use it really. I got this, but I think it's wrong....
| Code: |
<?php
include('connect.php');
$username = $_POST[username];
$password = $_POST[password];
$sql = "SELECT * FROM accounts WHERE username = '$username' AND password = '$password'";
if(!mysql_query($sql, $con)) {
echo "Invalid username or password!";
exi();
}
else {
start_session();
//then what o.O
}
mysql_close($con);
?>

I'm not the best person with PHP but this should work 
| Code: | <?
include("connect.php");
if($_SESSION['uname'] <= ""){
echo ' | <a href="otherfeatures.php">other features</a> | <a href="other features.php">Other features</a>';
} else {
echo ' | <a href="otherfeatures.php">other features</a> | <a href="other features.php">other features</a>';
}
?>
<br>
<strong>
<center>
<?
$submit = $_POST['submit'];
$uname = $_POST['uname'];
$pword1 = $_POST['pword'];
$pwordq = stripslashes("$pword1");
$what = array('"');
$then = array('');
$output = str_replace($what, $then, $pwordq);
$pword = $output;
if($_POST['submit'] == "1"){
$checkpass = "SELECT password FROM accounts WHERE name = '$uname'";
$checkpassq = @mysql_query("$checkpass");
$checkpassr = @mysql_result($checkpassq,0);
$checkpass = "SELECT name FROM accounts WHERE name = '$uname'";
$checkpassq = @mysql_query("$checkpass");
$num_rows = @mysql_num_rows($checkpassq);
if($num_rows > "0"){
if($pword == $checkpassr){
$_SESSION['uname'] = $uname;
$_SESSION['log'] = "yes";
echo "Whatever you want your message to display after login ( will redirect after 3 seconds ).";
echo "<meta http-equiv=refresh content=3;url=/>";
} else {
echo "The information you have entered is incorrect.";
}
} else {
echo "That account has not been registered";
}
}
?>
<b><form method="post">
<input type=hidden name="submit" value="1">
Username:
<input type=text name="uname"><? if($uname == "") { echo '<font color=red>*</font>'; } ?><br>
Password:
<input type=password name="pword"><? if($pword == "") { echo '<font color=red>*</font>'; } ?><br>
<input type=submit value="Login">
</form>
</b></font>
</center>
</STRONG>
