PHP pass variables to another php script

[hey101]

Well basically here is what I have so far. I have a form where a user inputs things. Then It sends it to a php script which does some work with it. What I want it to do is have a user send enter the stuff in the form, it then gets submited to my script, and my script passes the variables onto another website.

 

Now I already have the variables sent via post to my script. I need them to be sent on to the other website using post too. I have no control over the other website. I just know what variables i have to send. And i do not want the user to have to enter his info all over again just so it gets sent to the other site.

 

So how can i pass along post variables?

 

I asked at another forum and they said i was trying to do something fishy. well im not because:

 

Its a guys website at my school. He just wants an extra layer of security to where u have to go through my site to get to his. Kinda weird i know but he already has it setup on his side and is reluctant to change it. So I already have everything setup accept this. cookies and all that.

Does the other site receive the data POST or GET?

 

If it's GET put it in the URL.  If it POST put the URL of the other site in the form action.

they receive it through post. I dont want the user to have to refill in the form so passing it along in an invisible form would be nice if its possible

Put them in a session.

Look into curl as that will allow you to send data via POST to an outside website.

[Ken2k7]

Oh I assumed it would be the same site. Don't mind my previous post. Sorry!

[hey101]

I have tried looking at curl but i do not understand it. It is installed on both servers. Can you post an example on how I could use it?

PHP Curl Send Post Data

[Ken2k7]

We can't tell you if cURL is installed on both servers. We assume it is. As long as PHP is installed, it should have it. cURL

 

Edit - if you think you'll understand cURL by reading, you're sadly mistaken.

[hey101]

I already know it is installed. ok I saw this example on the internet:

 

<?php
$urltopost = "http://somewebsite.com/script.php";
$datatopost = array (
"firstname" => "Mike",
"lastname" => "Lopez",
"email" => "[email protected]",
);

$ch = curl_init ($urltopost);
curl_setopt ($ch, CURLOPT_POST, true);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $datatopost);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$returndata = curl_exec ($ch);
?>

 

Well there is an array. And I think that is what gets sent on it looks like. If it is then how do i insert variables in an array.

PHP Using Variables Inside an Array

[hey101]

according to here:

http://us2.php.net/manual/en/language.types.array.php

 

"Using variables as array names no longer works in PHP5."

 

SO is there a way that i can make a variable be pulled as not a variable if you understand what i mean? Like convert a variable into just the text they entered so that way it will work with the array?

[Ken2k7]

That's not what that person is trying to say. Don't worry about that post. Just figure out what *you* need to do.

[hey101]

ok well i used the code above to send a variable. Well it atleast sends something to the other server because it logs it but it logs nothing. Like i just setup a demo script to test it. the first script logs what the user put in a text file. Then is sopposedly sends that variable to the other script. The other script logs it in a different text file. Both should say this in the text file

test: (whatever was entered in the variable)

 

The first text file is fine. The second text file has just this in it

test:

 

SO what code should i have at the receiving end to actually get the variable that i send?

[Ken2k7]

What are you trying to pass over? Other than that copied code you got off somewhere, you haven't given us anything to help you with.

[hey101]

ok well heres is what im using to send the variables:

 

$test2 = $_POST['testing'];

$urltopost = "http://websitehere/test.php";
$datatopost = array (
$test2,
);

$ch = curl_init ($urltopost);
curl_setopt ($ch, CURLOPT_POST, true);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $datatopost);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$returndata = curl_exec ($ch);

?> 

 

I recieve it using

 

$test = $_POST['test2'];

$test3 = "Test: $test";

$file = fopen("test.txt", "a");
fputs($file, "$test3\r\n");
fputs($file, "\r\n");
fclose($file);

 

there you go. What am I doing wrong since the second file isn't receiving the variable.

 

 

For defining the first variable i use a html form.

[Ken2k7]

var_dump($returndata);

 

[hey101]

which script do i place that in and where do i place it? Im guessing the first script at the end?

[Ken2k7]

*Ken2k7 glares at hey101

 

You only have *ONE* script that has the variable $returndata in it.

[hey101]

Sorry i wasn't even thinking before i posted that. sorry

 

I will ttest it in a minute
