Let's Learn Coding .: February 2013

tonight.. i just playing with PHPcoding.

Start with login page but first i will create new folder in my server.

[dora@localhost public_html]$ mkdir project2
[dora@localhost public_html]$ ls
project1  project2  rnd  smf  test

[dora@localhost public_html]$ cd project2
[dora@localhost project2]$ nano -w index.php


<html><head><title>Title</title></head><body>
<form method="post" action="login.php">
<label>Username</label>: <input type="text" name="username" />
<br />
<label>Password</label>: <input type="password" name="password" />
<input type="submit" value="Log In" />
</form>
</body></html>






done.

then i do the "processing"

[dora@localhost project2]$ nano -w login.php



[?php

$username = $_REQUEST['username'];
$password = $_REQUEST['password'];

if ($username === 'Darlinx' && $password === 'Darlinx') 
echo "Password correct";
else echo "Password incorrect";



Form eXplaination ::

[?php = is a tag to php form.

in this process the form will received input.
it will retrieve from global << [input name="username"

$username $password = example of variable.

echo = is for output. print as 'text'

** when u submit the first form (login) the data will be
   transfer to login.php

now we need a comparison. I will set the input for "username" & 
"password" here. :)







ok. now i want to create "table" in my form.

let say i hav $x number of rows & $y number of columns
create new php file.

[dora@localhost project2]$ nano -w table.php

<?php

$x = 3;
$y = 5;

echo "<table>";
border="1"
for ($i = 0; $i < $x; $i++){
        echo "<tr>";
        for ($j = 0; $j < $y; $j++){
        }
                for ($j = 0; $j < $y; $j++){
                echo "<td>row $i col $j</td>";
                }
}
echo "</table>";



form eXplaination :

** this is what we call nested loop

LOOP ROWS WHILE ROWS IS LESS THAN 3
     PRINT ROW OPENING
          LOOP COLUMNS WHILE ROWS IS LESS THAN 4
               PRINT COLUMN WITH ROW NUMBER AND 
               COLUMN NUMBER
          LOOP END
     PRINT ROW CLOSING
LOOP END




try to add border since. :X

but.. that's how the loop working. i understand now. :)
