Register,login,logout - php tutoriale da se to nebi desavalo buducim "programerima" i "web-dizajnerima" odlucio sam da postavim ovaj mali tutorial i ucinim ga dostupnim svakome kome zatreba a siguran sam da hoce.
Pa dobro da pocnemo:
1 - kreirajte bazu podataka (nazovite je kako hocete, u mom slucaju ona se zove new)
2 - tablu takodje nazovite kako hocete, u mom slucaju ona se zove users
3 - br. polja 3
4 - prvo polje ID, type - mediumint, Length/Values - 9, Extra - auto_increment, i oznacite je kao primary (prvi radio button sa ikonicom kljuca)
5 - drugo polje username, type - varchar, Length/Values - 60
6 - trece polje password, type - varchar, Length/Values - 60
7 - kreirajte fajlove add.php, login.php, members.php, logout.php
8 - napomena: ovaj sistem radi pomocu cookia
9 - sve sto je potrebno da uradite je da napocetku svakog fajla zamjenite sledece:
mysql_connect("localhost", "root", "password") or die(mysql_error()); ovo su postavke u localhostu
mysql_select_db("new") or die(mysql_error());
localhost - ime vaseg hosta
root - vas username
password - vas password napomena: passworda nema u localhostu pa tu ostavite samo navodnike""
new - ime vase baze
A evo i kodova od tih fajlova
add.php
Code:
<?php

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'")

$check2 = mysql_num_rows($check);
//if the name exists it gives an error
if ($check2 != 0) {

// this makes sure both passwords entered match
