<form action='page2.html' method='POST'>
</form>

ok , here we need an input for put the data , like name , password , image or file uploaded , text befor searching, buttom ...., All of these things called input , We put them inside the form

<input type="" name="" value="">
all input Must contain
the type : text , password , submit ,file
the name : You choose the name, because you need the next page you made commitments for programming.
the value : it is text that is writting at the input .

<html>
<head>

</title>
</head>
<body bgcolor='red'>

<form action='page2.html' method='POST'>

use RANDOM function in php , with a database (by class)

hello ,
the RANDOM function is the best and easy . read here
but what is the interest ?

we use this edea by writting a script PHP .
if the result of random function exist at our database that we will create then do no thing
else add this result value to this database
we create a database . called RND . If you do not know how to creat a database read here
and , we create a table called rnd_table , Contains Only one field
called val : int(20)
ok .

Such as habit we create a scripte PHP for Contacting to our database RND .

but in this cour we use the class .

if you do not know what is a class read PHP class

we create a file (Ourclass.php) .

<?php
class contact_db{
public $localhost="localhost";
    public $username="root";
    public $password="root";
    public $db_name='rnd';
    public $tbl_name="rnd_table";
public $r=array();
function __construct(){ // this function is Present in the time of calling to class
mysql_connect($this->localhost,$this->username,$this->password) or die ('can not connect to data base ');
mysql_select_db($this->db_name) or die('can not select database ');
echo $db_name;
}
function get_elements_db(){ // this function get all elements of database and puts them in array
$sql="SELECT * FROM $this->tbl_name";
$result=mysql_query($sql);
$num=mysql_num_rows($result);
if ($num==0) echo "sory , no elements !!";
else {
$j=0;
while ($rr=mysql_fetch_array($result)){
$r[$j]=$rr['val'];
echo $r[$j]."<br>";
$j++;
}}}
}
?>

ok , the scripte ourclass.php give all values from table of database that we create ,
if no data , then it show (sory , no elements !!)

we creat a new file called (index.php) and we use the last scripte befor give a random value for Every time .
but , here we add a test , in our script if the value exist at our database show true else show false

to be continued ... :)

cour 3 : what is the action of our login form ? (PHP)

hello .
in cour 1 and 2 , we create a login form by HTML and CSS
in this cour we ask this question :

what is the action of our login form ? what is the Interest ?

ok , in this point , we need a edia befour starting .
1-the user enter a username and password
2-i say that only if user enter (username="admin" and password="admin") . he can sees "hello" at Level of our page exemple.php . else he sees "error".

ok , its simple , What do you think that we are testing?

open your file (exemple.php) and add this code PHP :

you can learn about PHP from all of PHP
we define 2 variables , $username and $password
$username give its value from $_POST['name'] ( value of input of name='name') by the method POST .
the $_POST is Matrix help us to give the values of different input as last input and the input of password .
$password , The same thing ,but it give his value from $_POST['password'] (the second input)

ok , if the value of $username='admin' and $password='admin' then show (in php echo "") hello
else show error.

so , i say that we need a data base , no only (admin) can see "hello"
all users can see this , but if they are registered at data base .

in the next cour , we use to create a data base , and we know what is SQL , and how to use it .

i hope that the cour is simple and easy , try to get the correct result .

reminder :
Do not forget, that you move your 2 files (exemple.php and style.css ) to directory (c:\appserv\www\)
if you want to try your page at Browser , write at adress ( localhost/exemple.php)

ok . that's all

thank you .
