so,how r u?fine?not so fine?emm..wanna some aspirin?i got some,heh.So,its quite long i doesn't post ,to be honest ,i'm quite forget what we learn the last post,doesn't a matter because this code below may remind us..huhu,just maybe or maybe not...whatever,hehe:
<html>
<head>
<title>The First HTML form</title>
</head>
<body>
<FORM NAME ="formOne" METHOD =" POST" ACTION = "">
<INPUT TYPE = "Submit" Name = "SubmitOne" VALUE = "Login">
</FORM>
</body>
</html>
u remember ryte? if not?just click here.So for this post we will concentrate on this line:
<INPUT TYPE = "Text" VALUE ="username">
change that line to this:
<INPUT TYPE = "Text" VALUE ="username" NAME = "username">
The NAME of our textbox is "username". u can use the other name like namewoo,lor or anything name that u like but for this post ,we will use "username".
So,add this code :
<?PHP
$username = $_POST['username'];
print ($username);
?>
on head section of ur html code like this:
<html>
<head>
<title>The First HTML form</title>
<?PHP
$username = $_POST['username'];
print ($username);
?>
</head>
so,just run it and ignore this error :
Notice: Undefined index: username in.....
just click the button "login",u should see like this:
So the $_POST[] is an inbuilt function that u can use to get POST data from a form. If ur METHOD = "GET" on ur form, then u should change ur line to this::
$username = $_GET['username'];
u type the username,because NAME="username"...
so that why we type like this:
$_POST['username'];
if NAME="namewoo" then
$_POST['namewoo'];
as long ur method in ur form still METHOD="POST".
$username = $_POST['username'];
So PHP will look for a HTML form element with the NAME username. It then looks at the VALUE attribute for this form element. It returns this value for you to use and manipulate.
<INPUT TYPE = "Text" VALUE ="username" NAME = "username">
in this case the Value ="username",that why when we run the script,we can see word "username" inside the textbox.
so,we manipulate it by change this code to like this:
<html>
<head>
<title>The First HTML form</title>
<?PHP
$username = $_POST['username'];
if ($username == "master") {
print ("Welcome back, master!");
}
else {
print ("You're not a member...");
}
?>
</head>
<body>
<FORM NAME ="formOne" METHOD ="POST" ACTION = "">
<INPUT TYPE = "Text" VALUE ="username" NAME = "username">
<INPUT TYPE = "Submit" Name = "SubmitOne" VALUE = "Login">
</FORM>
</body>
</html>
so,run the code.u should see like this:
then u type "master" inside the textbox,click button.u should see like this:
that all for today..
tq
N\Note :any question?lor
