Hi

 

Something like this:-

 

$trades  = (($_POST["T1"]) ? $_POST["T1"]."," : "");
$trades .= (($_POST["T2"]) ? $_POST["T2"]."," : "");
$trades .= (($_POST["T3"]) ? $_POST["T3"]."," : "");
$trades .= (($_POST["T4"]) ? $_POST["T4"]."," : "");
$trades .= (($_POST["T5"]) ? $_POST["T5"]."," : "");
$trades .= (($_POST["T6"]) ? $_POST["T6"]."," : "");
$trades .= (($_POST["T7"]) ? $_POST["T7"]."," : "");
$trades .= (($_POST["T8"]) ? $_POST["T8"]."," : "");
$trades .= (($_POST["T9"]) ? $_POST["T9"]."," : "");
$trades .= (($_POST["T10"]) ? $_POST["T10"]."," : "");
$trades .= (($_POST["T11"]) ? $_POST["T11"]."," : "");
$trades .= (($_POST["T12"]) ? $_POST["T12"]."," : "");
$trades .= (($_POST["T13"]) ? $_POST["T13"]."," : "");
$trades .= (($_POST["T14"]) ? $_POST["T14"]."," : "");
$trades .= (($_POST["T15"]) ? $_POST["T15"]."," : "");
$trades .= (($_POST["T16"]) ? $_POST["T16"]."," : "");
$trades .= (($_POST["T17"]) ? $_POST["T17"]."," : "");
$trades .= (($_POST["T18"]) ? $_POST["T18"]."," : "");
$trades .= (($_POST["T19"]) ? $_POST["T19"]."," : "");
$trades .= (($_POST["T20"]) ? $_POST["T20"]."," : "");
$trades .= (($_POST["T21"]) ? $_POST["T21"] : "");

 

All the best

If T1 to T21 is the only thing you have in your array then do the following:

 

$trades  = implode(',', $_POST);

 

Else you could extract those values by walking the array and taking the values if they start with T. For example:

 

$ExtractedResults = array();
function GetTFields(&$item1, $key){
global $ExtractedResults;
if(substr($key, 0, 1) == 'T' && is_numeric(substr($key, 1)) && (int)(substr($key, 1)) >= 1 && (int)(substr($key, 1)) <= 21){
$ExtractedResults[$key] = $item1;
}
}
array_walk($_POST, 'GetTFields');
$trades  = implode(',', $ExtractedResults);

Sorry i didnt read the post correctly, but you could take my second advice and simply put another condition that checks if the value is set...
