pass form info to a form on another page

[RussellH]

I posted this question and got some help that did and didnt work.

What I want to do is pass info entered into one text feild onto a text feild on another page.

When I tried this I was able to transfer the info on to the next page if I used the second pages name in the form action feild..

...................(this is how the first page is set up)

<?php
session_start();
?>

<html...

<form action=test2.php method=post>
<input type=text name=email>

</form...
</html...

..............(the second page like this)

<html...

<input type=text name=email value=<?php echo $POST = isset($POST) ? $_POST : $HTTP_POST_VARS['email']; ?>>

</form...
</html...

the above worked...

But when I tried to enter the actual script url into the form action tag (cgi-bin/suscribe.cgi) none of the info would transfer to the second form. The suscribe.cgi file processes the info and then redirects the visitor to a url that is defined with in one of the cgi files.

Is there a way to store the info and still get it to transfer to the second form?

thanks

I saw that you are using sessions. Why don't you register the value simply?

$session_email=$HTTP_POST_VARS['email'];
session_register("session_email");

Than you could call the value in any other page you wish, simply by writing

echo $session_email;

That code does not look like it would work properly for the second page, this would work better (assuming you have a recent version of PHP, otherwise use HTTP_POST_VARS instead of POST):

<input type='text' name='email' value='<?php 
    if(isset($_POST['email'])) echo $_POST['email']; ?>'>

Using session_register() depends on globals being on, which can compromise the security of your variables. The cleaner method would be to set and access it through the $SESSION array and forget about session_register()

set:
[b]$_SESSION['session_email']=$_POST['email'][/b]
retrieve:
[b]$session_email=$_SESSION['session_email'];[/b]

However, in this case if the value is present in the $_POST array, there is no reason to hit the disc for a session variable at all.

Still no luck, I tried both but couldnt get it to work

<input type='text' name='email' value='<?php
if(isset($POST['email'])) echo $POST['email']; ?>'>

&

$session_email=$HTTP_POST_VARS['email'];
session_register("session_email");

Than you could call the value in any other page you wish, simply by writing

echo $session_email;

I'm not sure what I'm doing wrong here. Could I possibly get a cut and paste of exactly what should go on the first and second page.

and thanks for the help so far.

What does it display as a value? Did you try it with HTTP_POST_VARS?

<input type='text' name='email' value='<?php
if(isset($HTTP_POST_VARS['email'])) echo $HTTP_POST_VARS['email']; ?>'>

After you get it working you would actually change the input type to 'hidden' instead of 'text' and probably handle it a bit different, assuming the value passed validation. Of course, since it is still in the control of the client you would probably still want to do another round of validation before actually doing anything with the data.

Nothing is displayed on the second form as a value. I can only see the php tag in the html code, but once its on the net and I call if from my browser I get a blank text field.

I jusst tried this code but still no luck

<input type='text' name='email' value='<?php
if(isset($HTTP_POST_VARS['email'])) echo $HTTP_POST_VARS['email']; ?>'>

Could the reason that its not working be because of the info being processed through the cgi script first and then being redirected to the second page throught the script? It works when I change the form action to page two instead of the scritp.

If this is possible, is there a way to store the info on my server and then have it auto entered into the second form?

thanks again for the help so far.

Well YEA, if you are posting the first form to a cgi script, then any problems displaying form information in the second page would be a result of the cgi script not passing them back, or at least not passing them back in the manner you are requesting them.

Why do you need a cgi script? I am assuming it is a PERL script? PHP is capable of anything PERL is. I would be inclined to go with one or the other, or if you need a hybrid system for some reason I would do all the PHP stuff before passing it to the CGI script. Passing it back and forth, to me, seems a bit excessive.

If the CGI script is passing the values back to the second page via a redirect or something they might be arriving on the GET. Do you see the values in the URL? If so, change HTTP_POST_VARS to HTTP_GET_VARS.

something like this:
<input type="hidden" name="emailaddress" value="$somevar">

[darknuke]

you dont need any perl/cgi script or any script, just simple that so the data will be passed on to a form processor/script

[RussellH]

Hey whats going on,

it's actually a cgi script that takes a visitors email address sends it out to a few different places including my mailing list. On the next page I have a different form that asks the visitor if they would like to suscribe to another mailing list. But I want the email address to already be entered in the text feild to get a better ratio of visitors suscribing to the second list.

To be honest I'm new (very new) with php and didnt realize it could do all of that. But I already have everything up and running. And then I heard I could get the email address added to the second page with php sessions. Will I have to do this with a cgi script since the info is being processed with a cgi script, can a cgi script do it? Or is it possible to take the email from the first page and put it into the second page with php even though the info is being processed through a cgi script?

[MrAlaska]

To carry the email variable without using sessions, you would need to get the cgi script to pass it back. I am assuming the CGI script returns the user to the second page via redirect, so you could include the email address in the URL then PHP could retrieve it via the GET.

To use $_SESSION to remember the email, you would first set the variable on the first PHP page. Since the first page is posting to a non-php script, that would be a bit tricky. You would need to have an intermediate PHP page intercept the post, register the session variable, then pass the variables on to the cgi script. That could get a little tricky if the cgi page is expecting values via the POST.

Off hand, I cannot think of a simpler way to go about it, except to just have PHP do everything 🙂 I have never played with posting stuff back and forth, though, there might be a cleaner method.
