Hi,
Iīve just started using php, and iīm trying to make it work with wampserver!
Iīm using wamperver 2 , PHP 5.30
on windows 7
I have installed wampserver correctly and the localhost seems to work.
When i try this script:
<?php echo "something" ?>
It works!
But when I try to send information from a html file to php file, the varibel doesn't go throw. I get this message: Notice: Undefined variable: name in C:\wamp\www\php\results.php on line 3
Please guys help me out :( -
<html xmlns="http://www.w3.org/1999/xhtml">
-
<head>
-
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
-
<title> Connect To Database</title>
-
</head>
-
<body>
-
-
<form action="results.php" method="post">
-
<input name="name" type="text" value="name">
-
<input name="" type="submit" value="search">
-
</form>
-
-
</body>
-
</html>

The form uses the method "post," as you can see in the <form> element's attributes. So, you will find the values from the form in the $_POST superglobal array in PHP. - if (!empty($_POST)) { // A form has been submitted
-
if (!empty($_POST['name'])) {
-
echo $_POST['name'];
-
}
-
}
Thanks for the help kovik =)
Now there are no errors, but the browser page is emty! It doesnīt show anything...donīt know why!
Try to print_r() the $_POST array to see if anything has been submitted.
No, nothing.
I tried this: - <?
-
if (!empty($_POST)) { // A form has been submitted
-
if (!empty($_POST['name'])) {
-
echo $_POST['name'];
-
}
-
}
-
-
print_r($_POST);
-
?>
Then that means that nothing has been submitted. The $_POST array only has data after you press the submit button on a form that posts to the page.
Ok, I see. But script is right for both php and html right?
So what is the problem then, what have i done wrong?
As I said before when i just "echo" something it does show up..
But of course I understand itīs difficult for you to point the problem out with the information provided by me.
Thanks anywaym, please let me know if you get an new idea =)
What I'm trying to tell you is that you have to test this page AFTER pressing the submit button...
A better way to do it is to keep it in the same page: - <?php
-
print_r($_POST);
-
?>
-
<form method="post" action="#">
-
<input type="text" name="name" value="" />
-
<button type="submit">Submit</button>
-
</form>
ok sorry, didnīt understand that. This is very new for me =p
I tried that out and got this message in the browser when I typed hello;
Array ( [name] => hello )
Good. That means that if you echo $_POST['name'], it would output "hello."
yes it does, it (action = "#") but not when send it to another page.
But I can live with that for now I guess.
thanks a lot =D
It should work fine going from one page to another. Not sure what went wrong with yours, but it is still common practice to submit forms to the same page
I dont know why it doesnīt work, I use this script for the html and php file: - <body>
-
<?php
-
echo $_POST['name']
-
?>
-
-
<form action="#" method="post">
-
<input name="name" type="text" value="name">
-
<input name="" type="submit" value="search">
-
</form>
-
-
</body>
- <?
-
if (!empty($_POST)) { // A form has been submitted
-
if (!empty($_POST['name'])) {
-
echo $_POST['name'];
-
}
-
}
-
echo $_POST['name']
-
?>
The "action" attribute of the <form> element must correspond to the file that should be receiving the data.
Tried that 2 doesnt work. :/
Programming canīt be this hard lol
meybe itīs something wrong with wampserver.. dont know..
That is doubtful. Trying echoing something identifying in the receiving file, like "This file is X." I suspect that you are submitting the form to the wrong file.
Also, it's probable your PHP configuration has PHP's short-opening tags disabled. Always use <?php over <?.
YEEEEEEEEEES!!!!
Now it works, I used <?php instead of <?, But thats strange I used that in my first post, but it didnīt work. Well now it does thanks to Kovik and Markus. =))
The reason it didn't work in the first post is because you were using $name instead of $_POST['name']. $name would only exist if you had register_globals on, which is recommended against because of security reasons.
Aha ok, thanks for the explanation. And for all the help.
