@NogDogAug 12.2010 — #Rather than redirecting, I'd probably use the [url=http://php.net/curl]cURL functions[/url] to submit the data from your form-handler page to the other URL, then parse the response and display whatever you want as a result of it.@NogDogAug 12.2010 — #Actually, I think I read more into your question than was there. For some reason I was thinking you wanted to submit the data to another site, then have it redirect back to yours. I'm a bit tied up at the moment, but I'll get back here later with some ideas. @NogDogAug 12.2010 — #So anyway, all you need to do is have ex.php do all the nitty gritty stuff to process the form input without outputting anything (including anything not within the <?php tags), then do a header() to the desired "landing page".
However, I often like to have the form page also be the processing page, so that it's easy to redisplay the form with any errors should the user screw up somewhere, so it might go something like:

Heh...I guess I'm just not with it today...sort of a virtual Friday for me. ?
I've found I've had better success setting the data as a string instead of an array (being sure to urlencode the data):
@NogDogAug 17.2010 — #The rest of your cURL code looked OK, I was just suggesting a change to how you use curl_setopt() for the CURL_POSTFIELDS setting. If we assume $data is an array that has your form data to be transmitted, where the array keys are the field names, you can use a little looping to do it:

No, that would be the URL to the external script you want to send the form data (or some subset of it) to for further processing. Your form's action would be the script where we're doing this cURL stuff, the cURL stuff would send the data via HTTP request (doing the same thing your form did to send its data to your script, but now sending it to the external site) and wait for the response from that external script, which will be returned by curl_exec().
PS: Just to clarify, the attached image is my understanding of what you want to do.

Does that jibe with what you are thinking, or have I gotten it confused?@NogDogAug 18.2010 — #After doing the curl_exec() (and doing some error-checking to see if it worked ? ), I would do a header() redirect to the success page. If you want to carry over some or all of the form data to that page for displaying feedback to the user or whatever, I would make use of PHP sessions.
Redirecting after form is submitted
Say I have a form like so:
<form action=”ex.php” method=”post” name=”frm”>
<input type=”text” name=”fn” />
<input type=”text” name=”ln” />
<input type=”button” value=”submit” />
</form>
I need these input values to be posted to ex.php and once submission is done redirected to a different .php or .html page after. Basically, I would like it to look like the viewer never even went to ex.php. Does that make sense? Sorry if I am confusing!!!!

@NogDogAug 13.2010 — #This is exactly what I want (what you said above)...
Sorry I made things so confusing. I need to submit data to another URL and redirect back to mine. I have been reading up on CURL, but haven't figured it out yet.[/QUOTE]

I've found I've had better success setting the data as a string instead of an array (being sure to urlencode the data):
[code=php]
$data = array();
$data[] = 'foo='.urlencode($_POST['foo']);
$data[] = 'bar='.urlencode($_POST['bar']);
// etc....
// use implode() to create the data string:
curl_setopt($ch, CURLOPT_POSTFIELDS, implode('&', $data));

So this is the path to my html with the form on it?
Where do I put the URL that the form is being sent to?[/QUOTE]
No, that would be the URL to the external script you want to send the form data (or some subset of it) to for further processing.
