Yea... For my do_login.php script; the code is posted below <?php session_start(); require('incfiles/init.php'); if(functions::isloggedin()) { if(empty($redirect)) { functions::go($config->url); } else { functions::go('http://'.$redirect); } die(); } if(isset($_POST["submit"])) { //STEP DOWN VALUES $username=$_POST["username"]; $password=$_POST["password"]; $redirect=$_POST["redirect"]; //CLEANUP VALUES $username=functions::cleaninput($username); $password=functions::cleaninput($password); $password=md5($password); $checkquery=mysql_query("SELECT username, password FROM users WHERE username='$username' AND password='$password'" or die(mysql_error()); $num=mysql_num_rows($checkquery); if($num>0) { $banq = mysql_num_rows(mysql_query("SELECT * FROM `bannedusers` WHERE `username`='$username' AND `boardid`=0"); if($banq > 0) { $binfo = mysql_fetch_array(mysql_query("SELECT * FROM `bannedusers` WHERE username='$username'"); $reason = $binfo["reason"]; $date = $binfo["date"]; $unbandate = $binfo["unbandate"]; $today = time(); if($today < $unbandate) { $pagetitle = "You Have Been Banished By one of the Administrator!."; require('incfiles/head.php'); $ud = date('l jS F Y \a\t g:I A', $unbandate); $bd = date('l jS F Y \a\t g:I A', $date); echo "<h2>You Have Been Banished By one of the Administrator!.</h2><div class='display'><p>Reason: $reason<p>Banned Date: $bd<p>Unbanned Date: $ud</div>"; require('incfiles/end.php'); die(); } else { mysql_query("DELETE FROM bannedusers WHERE username='$username' ANd boardid=0" $pagetitle = "U have Just Been Unbanned"; require('incfiles/head.php'); $msg="U Hav Just Been Unbanned Pls Go Back And Login Again"; echo "<div class='display'>$msg<br/><a href='javascript:history.go(-1)'>Go back</a></div>"; } } else { $CookieExpire = 100000; $time = 60 * 60 * 24 * $CookieExpire; $time = time() + $time; $key = $username . date('mY'); $key = strtoupper(md5($key)); setcookie("sessionkey", "$key", "$time" setcookie("user", "$username", "$time" setcookie("password", "$password", "$time" $_SESSION["user"]=$username; $id=functions::user_info($username, userID); $date=date(); $guestip=$_SERVER["REMOTE_ADDR"]; $guestbrowser=$_SERVER["HTTP_USER_AGENT"]; mysql_query("UPDATE b_guestsonline SET time=1 WHERE browser='$guestbrowser' AND guestip='$guestip'" mysql_query("UPDATE users SET sessionkey='$key' WHERE username='$username'" if(empty($redirect)) { functions::go($config->url); } else { functions::go('http://'.$redirect); } } } else { $pagetitle = "incorrect username and/or password, make sure you type correctly your username & password !"; require('incfiles/head.php'); $msg="incorrect username and/or password, make sure you type correctly your username & password !"; echo "<div class='display'>$msg<br/><a href='javascript:history.go(-1)'>Go back</a></div>"; } } else { $pagetitle = "Error"; require('incfiles/head.php'); $msg="Error"; echo "<div class='display'>$msg<br/><a href='javascript:history.go(-1)'>Go back</a></div>"; } require('incfiles/end.php'); ?> |

Abiodun2014: Haba! That is unecessarily long na and even introduces a lot more than was asked. please use this on login page //collect username and password: $username = $_POST['password']; $password = $_POST['password']; //...verify and validate your username and password (I guess you know how to do that) //set cookie $time = time() + 60 * 60 * 7 * 30; setcookie("user", $username, $time); setcookie("password", $password, "$time" //log user in } // now on the index page put //check to see if user already has a session: if(isset($_COOKIE['user'])){ //if yes, collect username and password from cookie instead of login form: $username = $_COOKIE['user']; $password = $_COOKIE['password']; //....verify and validate then log user in automatically. } Hope this helps. I'm a fan of short clean code. |

larisoft: It didn't work oooo |
Re: How To Create Sessions In PHP by larisoft: 10:07am On Apr 26, 2015 |
<?php $username = $_POST['username']; //corrected this $password = $_POST['password']; //...verify and validate your username and password (I guess you know how to do that) //set cookie $time = time() + 60 * 60 * 7 * 30; setcookie("user", $username, $time); setcookie("password", $password, $time); //corrected this too //log user in... } // now on the index page put <?php //check to see if user already has a session; if yes, collect username and password from cookie instead of login form: if(isset($_COOKIE['user'])){ $username = $_COOKIE['user']; $password = $_COOKIE['password']; //verify against database username and password and take user in. ?> } And my guy..abeg dey try read code small before you copy paste am. There are three ways to never really learn programming and yet be a programmer. They are 1. Copying and Pasting. 2. Copying and Pasting. 3. Copying and Pasting Ruthlessly |

larisoft:My nairaland look alike site loads very slow or doesn't load at all on Operamini alone. How can I solve this?! |
Re: How To Create Sessions In PHP by Nobody: 3:34am On May 08, 2015 |
All of you using mysql_connect or mysql_* I don't think it seems to work anymore, Use pdo or mysqli For the guy who's asking about a site not loading on opera mini, I suggest you don't open it with that at all, if the browser may have not been updated, it's likely to behave like that. Have fun |
Re: How To Create Sessions In PHP by AAinEqGuinea: 4:55am On May 08, 2015 |
Love it, love to see brogrammers coming together I'm starting trekking journey to unite programmers |
Re: How To Create Sessions In PHP by Abiodun2014(m): 12:50am On May 09, 2015 |
gimakon: Since mobile is taking ova now, users can't do without using their operamini browser because of its advantages. About the mysqli ish can u give me a citation; like an example to illustrate wat u mean! Thanks |
Re: How To Create Sessions In PHP by Nobody: 7:13am On May 09, 2015 |
Abiodun2014: Ok I wonna connect to a database for instance I do something like this
Ok, that's what it looks like. I'm writing from my BlackBerry, am not on computer now, so that's what a mysqli query should look like, hence u reading, try reading PDO too. Pdo is best for some php guys because they said you just get to change the parameter name for the rdbms and the user and pass, and can be used to connect any database then make something like a prepared statement. I should believe this helps... Have fun... PS : consider using real_escape_string() or stripslashes() to $_POST data, helps you secure your data from mysql injection. Thanks and God bless you |

gimakon: Thanks a lot would try that now! |
Re: How To Create Sessions In PHP by Abiodun2014(m): 7:40am On May 09, 2015 |
gimakon: It aint working showing can't connect to database |
Re: How To Create Sessions In PHP by Nobody: 9:17am On May 09, 2015 |
Abiodun2014: Did u create a database? Or u think copy pasting is what is called programming, a simple code that you have to debug is what is looking at you. I suggest you learn how to program and don't come here to embarrass yourself because of a simple program. The error looking at you can be easily solved if you know your way around mysql phpmyadmin Or you can echo create database and do the needful, programmers are not always told what to do, they study. So study and program. Thank u 1 Like |
