WHCS Price via API with dynamic array - php

Question

I want to know how to get WHMCS Price via WHMCS API.
I have created a little script to get price via API which is working fine but when I update the script on my external WHMCS pages it is taking a lot more time to update the function on each page my simple question is to get price via API without defining the first array see example below.
Array
(
[result] => success
[totalresults] => xxx
[products] => Array
(
[product] => Array
(
[0] => Array // how can I call it dynamically
(
[pid] => 1
[gid] => 1
[type] => hostingaccount
[name] => Plan Name
[description] => Plan Description
[module] => cpanel
[paytype] => recurring
[pricing] => Array
(
[USD] => Array
(
[prefix] => $
[suffix] => USD
[msetupfee] => 0.00
[qsetupfee] => 0.00
[ssetupfee] => 0.00
[asetupfee] => 0.00
[bsetupfee] => 0.00
[tsetupfee] => 0.00
[monthly] => 0.14
[quarterly] => 0.39
[semiannually] => 0.73
[annually] => 1.32
[biennially] => 2.39
[triennially] => 3.20
)
)
)
)
)
)
I just want to get price after I define [pid] and then I will create a function like
GetPrice($pid, $billingcycle); // to get produce price according to tenure
My Script:
$identifier = "IDENTIFIER";
$secret = "SECRET";
$APIURL = "mydomain/whmcs_directory/includes/api.php"; // it is with HTTPS
$postfields = array(
'username' => $identifier,
'password' => $secret,
'action' => 'GetProducts',
'responsetype' => 'json',
);
// Call the API
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $APIURL);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postfields));
$response = curl_exec($ch);
if (curl_error($ch)) {
die('Unable to connect: ' . curl_errno($ch) . ' - ' . curl_error($ch));
}
curl_close($ch);
// Decode response
$jsonData = json_decode($response, true);
and then I want to use function to get price according product id & tenure as defined earlier but complete function looks like this.
function GetPrice($pid, $billingcycle){
// $pid will be product ID
// $billingcycle will be 1,3,6,12,24,36 accordingly.
/**
* It would be great if I could just remove "["products"]["product"]"
* But I understand to call API I have define them so it's Okay.
*/
$monthly = $jsonData["products"]["product"][$pid]["pricing"]["USD"]["monthly"];
$quarterly = $jsonData["products"]["product"][$pid]["pricing"]["USD"]["quarterly"];
$semiannually = $jsonData["products"]["product"][$pid]["pricing"]["USD"]["semiannually"];
$annually = $jsonData["products"]["product"][$pid]["pricing"]["USD"]["annually"];
$biennially = $jsonData["products"]["product"][$pid]["pricing"]["USD"]["biennially"];
$triennially = $jsonData["products"]["product"][$pid]["pricing"]["USD"]["triennially"];
if( $billingcycle == "1" ){
echo $monthly;
}
if( $billingcycle == "3" ){
echo $quarterly;
}
if( $billingcycle == "6" ){
echo $semiannually;
}
if( $billingcycle == "12" ){
echo $annually;
}
if( $billingcycle == "24" ){
echo $biennially;
}
if( $billingcycle == "36" ){
echo $triennially;
}
}
I got help from WHMCS API Reference
This has done with php, please improve my code if require.

Answer 1

I have achieved this with the following code which work dynamically and works with product id.
PHP Function
function GetPrice($product_id, $billingcycle){
$identifier = "WHMCS_IDENTIFIER";
$secret = "WHMCS_SECRET";
$APIURL = "YOURDOMAIN.com/WHMCS_DIRECTORY/includes/api.php"; // use HTTPS
$postfields = array(
'username' => $identifier,
'password' => $secret,
'action' => 'GetProducts',
'pid' => $product_id, // Product id
'responsetype' => 'json',
);
// Call the API
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $APIURL);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1); // SET to 0 for non SSL
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postfields));
$response = curl_exec($ch);
if (curl_error($ch)) {
//die('Unable to connect: ' . curl_errno($ch) . ' - ' . curl_error($ch));
die("Out of Stock");
}
curl_close($ch);
// Decode response
$jsonData = json_decode($response, true);
$monthly = $jsonData["products"]["product"][0]["pricing"]["USD"]["monthly"];
$quarterly = $jsonData["products"]["product"][0]["pricing"]["USD"]["quarterly"];
$semiannually = $jsonData["products"]["product"][0]["pricing"]["USD"]["semiannually"];
$annually = $jsonData["products"]["product"][0]["pricing"]["USD"]["annually"];
$biennially = $jsonData["products"]["product"][0]["pricing"]["USD"]["biennially"];
$triennially = $jsonData["products"]["product"][0]["pricing"]["USD"]["triennially"];
if( $billingcycle == "1" ){
echo round( str_replace('.00', '', $monthly), 2 );
}
if( $billingcycle == "3" ){
echo round( str_replace('.00', '', $quarterly) / 3, 2 );
}
if( $billingcycle == "6" ){
echo round( str_replace('.00', '', $semiannually) / 6, 2 );
}
if( $billingcycle == "12" ){
echo round( str_replace('.00', '', $annually) / 12, 2 );
}
if( $billingcycle == "24" ){
echo round( str_replace('.00', '', $biennially) / 24, 2 );
}
if( $billingcycle == "36" ){
echo round( str_replace('.00', '', $triennially) / 36, 2 );
}
}
Using Function
echo GetPrice( 1 , 1 );
Output
1.99
