$_GET & $_POST

[Bob_PHP_Builder]

i have a problem with $GET &$POST... i have two php files, one requires a $GET and one requires a $POST.. i can get one (either $GET or $POST to work but not together..) does anyone know the reason for this?

$author = $GET['author'];
$author = $POST ['author'];

if i use both only the $GET will work
if i comment out the $GET the $_POST will work,

Your overwritting one variable with the other. Try...

$getauthor = $_GET['author'];
$postauthor = $_POST['author'];

[bodzan]

Not sure but it seems to me that register_globals are on so what you get when you use both is:

$author = $_GET['author'];
$author = $author;

If that is the case try naming those differently as thorpe suggested and you should be O.K...

[Bob_PHP_Builder]

Thank you for replying to my post..

i have just changed the variables.. however the author variable still will not send to both

ill post my code

upload.php - this is referenced first

$postauthor = $_POST ['Author'];
$galleryPath = realpath("Gallery");
$Thumbnail= 'Thumbnail';

mkdir($galleryPath . "/". $postauthor , 0700);
$absGalleryPath = realpath("Gallery" . "/" . $postauthor). "/";
mkdir($absGalleryPath . "/". $Thumbnail , 0700);
$absThumbnailsPath = realpath("$absGalleryPath" . "/" . "Thumbnail") . "/";

gallery.php

$getauthor = $_GET['Author'];
echo "$getauthor";
$absGalleryPath = realpath("Gallery" . "/" . "$getauthor"). "/";
$absThumbnailsPath = realpath("$absGalleryPath" . "/" . "Thumbnail") . "/";

[Bob_PHP_Builder]

the $_GET variable has nothing there.. i tried an echo

[thorpe]

What is the output of...

print_r($_GET);
print_r($_POST);

Also... how are you sending these variables? I assume you have a form with an action something like...

<form action="foo.php?Author=bar" method="post">

sorry about the formatting

[bradgrafelman]

Why not just use this?

$author = $_REQUEST['author'];

EDIT:

sorry about the formatting

That's what the [ PHP ] [ /PHP ] tags are for! Make sure to use those when posting PHP code - it makes it a lot easier for people to look at, plus it's even color coded :p

[Bob_PHP_Builder]

I have tried the $REQUEST instead of the $GET, however im still getting the error. 😕

😕

plz help

[Bob_PHP_Builder]

actually all i need is to get the $author variable to gallery.php

$_post works in upload.php

[halojoy]

remember
$GET['Author'] is NOT same as $GET['author']
my solution is to always use lower case variable characters
I guess especially when a GET variable is a part of an URL
like 'page.php?Author=something' this can be an issue.

so both on the 'sending, setting' side, use the same:
$author='xxxx'; and 'receiving' side
$get_the_author = $_GET['author'];

Also is a deadly sin for me, to name a website folder or file with any upper case letters

Index.php
and
/Images/
and
/Images/MyPicture.JPG
makes me feel real SICK, when I see it

( correct is of course: index.php ... /images/ ... /images/my_picture.jpg )
will spare you some troubles, sooner or later

🙂

$author = $_GET['author'];
$author = $_POST ['author'];

In your script u are rewriting your $author var with post value; when u go through POST is working when u go through GET is not working:
So make it this way ...

$author = '';
if (!empty($_GET['author'])) $author = $_GET['author'];
if (!empty($_POST['author'])) $author = $_POST ['author'];
if (empty($author)) die('No author has been selected!'); /*maybe a redirect is a good solution ...*/

When u add code on the forum please use php tags, like I use [ php ]your code in here[ /php ] and please reedit your posts where u add your code using php tags, thanks ...

[Bob_PHP_Builder]

Thanks all for the replies!!!!

i still seem to have the same problem.. however could the problem lie in
[ php ] iu.addParam("RedirectUrl","gallery.php"); [ /php ]

should i pass a parameter there?

[Eric_T]

Ok I know I'm new to PHP but $POST and $GET are dependant on the form method you use. So if you have one form and it's method is GET you will not be able to retrieve the information with $POST. The same is also true that if your forms method is POST you will not be able to retrieve the information with a $GET.

Also if you are trying to use the information on more than one page don't you need to make it a session variable or put it in the URL or can you retrive form data on more than one page?

So I would think that the flow would be like this...

Page One
<form method="post">
<input>
</form>

Page two 

author = $_POST['author']

redirect=wherever.php?author=$author or set it as a session var

Page three

$author = $_GET['author'] or use the session var

If u are new to php, u should know that u are on the right direction, thats one of the basic u should understand befor start creating web pages ...
Good luck and HF coding. 😃
