How do i pass variables from one page to another?

AlexRodr

Thank you for trouble,
I'am trying to pass one simple variable ($Zi="I2" in this case) from one page to another and so on...
How do i make the variable pass?

Add Zi=I2 to you link like this:
<a href="www.page.com?Zi=I2>link</a>

When you want to get the value of it, you type this in PHP:
$value = $HTTP_POST_VARS['Zi'];

you have three possibilities:

1.) with GET: call the next page with an URL like this: page.php?var1=value1&var2=value2...

-> on the next page you get the content with $_GET['var1'] ...

2.) with POST: use a html form, give all input fields a name
<input type=text name=var1>

-> get these with $_POST['var1'] (instead of $var1)

3.) with Sessions, don't be bothered now 😉

yes that should be $_GET['Zi'] or $HTTP_GET_VARS['Zi'], but not POST.

I do that, but the variables only pass from the form to the first file with php code, after that it is like they never have existed.
And if the variables do not came from a form...
Do i have to put all the the variable names in the link???
I have a lot of variables to pass on to the next pages.

Yeah, you have to pass them all..
And if you go to your second page, you still have to pass them..

Check your location-bar: http://www.phpbuilder.com/board/newreply.php?s=&action=newreply&threadid=10235724

It passes all vars too.. But to prevent it has to send so much vars, it has given you a unique id. It will pass that to every page. Every page reads that ID and grabs the information it needs from a database.

if you're using a form, just pass them to the third page using hidden inputs. If you have a lot of fields, then use a loop to create your hidden inputs. Put this on the second page of your form inside form tags and make sure the form gets submitted to the 3rd page.


foreach($_POST as $key => $value) {
   echo "<input type=\"hidden\" name=\"" . $key . "\" value=\"" . $value . "\">\n";
}
