Using PHP to pass paramters to a JSP

ChRoMe

Hey

Just a quick question. I have a php page that takes some input from html fields. I want to pass these values as paramters to a JSP. Any suggestions how I would go about this?

Thanks

You could pass them in the query string. Also have a look as jsp forms processing, you should find a solution in there.

Sorry I should have been clearer. A user inputs some details into a html form. This forms posts to a php page that does some modifications of the information submitted. I then want to post (or is it put?) these new values to a jsp page through the query string eg www.blah.com/blah.jsp?name=joe&phone=whatever

Once this is done Im going to use header to forward the user onto a page that thanks them for their submission.

So without any interaction from a user how can i get php to send this query string (should i be using the curl lib?) to the jsp?

Check out the CURL library for this. Seems ideal for what you want. This allows you to call a URL from your PHP script without redirecting the user.

I've been playing around with curl and cant seem to get it to pass the paramters to the jsp. Its my first time using it so its probbably an obvious mistake in the code. I'd be grateful if anyone with any experience of using it could have a look.

  $operator = $_POST['operator'];
  
  $phone = $_POST['phone'];
  
  $params = array("phone" => "$phone", "operator" => "$operator");
  
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, 'http://example.com/Handler.jsp');
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
  curl_exec($ch);

A quick search reveals a few people have problems passing the array to curl_setopt.

Best thing seems to be to construct the string yourself.

So
[php]

$post_string = "";

foreach($params as $k => $v) {
$post_string .= "$k=".url_encode($v)."&";
}

...

curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string);

[/php]

I'm not familiar with php but should the variables be enclosed in quotation marks? I've removed them below.

  $operator = $_POST['operator'];
  
  $phone = $_POST['phone'];
  
[b]  $params = array("phone" => $phone, "operator" => $operator);[/b]
  
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, 'http://example.com/Handler.jsp');
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
  curl_exec($ch);

Yeah, it's an associative array, so the key names should be enclosed in quotes.
