Hi Bob,
One thing I see is that you're appending values on to the end of a url that
already has 2 values, so you should place the "&" at the beginning of your
line instead of at the end. Value 2 is being merged with whatever value is
coming after it in your example. So, try something like:
$url .= "&" . $key. "=" .$post;
Also, I'd suggest url encoding the post value rather than merely hunting
down spaces and swapping them out with "+".
Hope this helps,
Adam

Instead of concatenating strings, I suggest to use the http_build_query()
function:
'val1',
'param2' => 'val2',
'param3' => 'val3');
$query = http_build_query($data);
echo "Query: {$query}\n";
?>
So, to create a query string based on your $_POST request parameters,
you just need to use the function as follows:
This will create the proper query string to be used on your URL.

[PHP] Suppressing error from displaying
I am using this syntax to check for a valid e-mail address
list($userName, $mailDomain) = split("@", $buyer_email);
if (checkdnsrr($mailDomain, "MX")) {
if no domain is provided ( ie e-mail address is something like “ron” with no @
) the following error is displayed:
Warning: checkdnsrr() [function.checkdnsrr]: Host and type cannot be empty
Can I suppress this from displaying so *just* my error message displays?

Just add @ before checkdnsrr:
list($userName, $mailDomain) = split("@", $buyer_email);
if (@checkdnsrr($mailDomain, "MX")) {
But you shouldn't use @ as it will make a PITA to find errors in your code
when maintaining it. You should not display Warnings on production too, at
least not for users but instead log those.

Sure.
if (@checkdnsrr($mailDomain,'MX'))

if ( @checkdnsrr($mailDomain, "MX") ) {
might work.. the @ symbol usually suppresses the error

Re: [PHP] curl and variable parameters in hyperlink
Guess I've not explained this very well. The external page I am fetching using another curl script has asp query hyperlinks in it. I do not know the variable names in each query or the values they have. All I want to do is replace the external url referenced in those links with a url which is on my site (so that I can change style sheet, image locations etc.) but the parameters to the original asp query link have to be captured and passed to my php script for it to return data. I know there must be a way of doing this as there's a site which is referencing the same third party site and doing the same thing, and no, they won't tell me how! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Which may force them to go out of business then you'll lose your source of information. 2) Waste of bandwidth. 3rd party > you > user instead of just you > user. 3) I'm don't like that fact that some people take others work and try to pass it as their own. I think many folks on this list feels the same way. So why not just quote them and give them the credit they deserve. That's probably the reason why you're not able to find much info on how to do this :) Regards, Tommy -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] curl and variable parameters in hyperlink
Thanks to all for your interest so far but as I said, new to PHP. Changed POST to GET and all now working fine! Tommy, the third party site is fully aware of what I am doing. We pay them to use the data, as do lots of other companies in our industry. Supplying data is what they do. We could not use the site at all without being given a valid user name. Far from 'preventing them being successful' the more users they have the more successful they become. We do not 'pass the work as our own' they are credited on our site as suppliers of the content, so there really is no issue there. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
