I have multiple XML_PAYLOAD's to post (different xml posts for each while loop). When I run the loop it will only POST the data of the first $i loop. How can I get it to POST new data for each $i loop?

$i = 0;
while ($i < $num) {

...data

define("XML_PAYLOAD", "<?xml stuff and tags?>");
define("XML_POST_URL", "http://theurl");

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, XML_POST_URL);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_POSTFIELDS, XML_PAYLOAD);

$result = curl_exec($ch);
curl_close($ch);

$i++;
}

It needs to be in there because it needs to have different data it pulls from the loop. –  ToddN Apr 5 '13 at 19:00
    
At first glance, the use of defines would be an issue. You can only define a constant once. So if your payloads are different in each loop, you wouldn't be able to redefine XML_PAYLOAD nor XML_POST_URL, so you would send the same thing $num times. –  EmmanuelG Apr 5 '13 at 19:05
    
of course, this makes sense thanks thus far. –  ToddN Apr 5 '13 at 19:07

define defines a constant. It means that it cannot change once it set. You should use variables like that:

define("XML_POST_URL", "http://theurl");
$i = 0;
while ($i < $num) {

...data

$xml_payload = "<?xml stuff and tags?>";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, XML_POST_URL);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_POSTFIELDS, XML_PAYLOAD);

$result = curl_exec($ch);
curl_close($ch);

$i++;
}
