Search Form & Drug Discount Network API
To allow website visitors to search the Discount drug Network API database, we first have to create an appropriate search form in HTML like so:
<!-- === DDNetwork - Search Form === -->
<div id="pharmacy__search" class="container mb-4">
<div class="row">
<form id="pharma__search2" action="<?php echo htmlentities(get_permalink());?>home#pharmacy__search"
method="post"
class=" mx-auto"
style="background-color: <?php echo $custom_search_form_main_bg_color;?>;
border-radius:10px;
border: 4px solid <?php echo $custom_search_form_border_color;?>;">

Next we must establish Connection with the DDN API like in the following PHP code
<?php
$wsdl = "https://api.***************.php?wsdl";
$login = array('login' => '**********',
'password' => '***********'
);
$soapClient = new SoapClient($wsdl, $login);
?>Drug Discount Network | Soap Request
After the visitor fills out the form and submits the data (pharmacy, drug, etc.), this information will be stored in the PHP predefined $_POST variable. We now want to get the search results from the discount drug Network via API. Therefore we have to make a SOAP Request including the data from our $_POST variable.
if(isset($_POST["search"]) ):
$drug_name = strtoupper($_POST["drug_name"]);
$zip_code = $_POST["zip_code"];
$formulation = $_POST["formulation"];
$strength = $_POST["strength"];
$strength_unit_of_measure = $_POST["strength_unit_of_measure"];
$package_size = $_POST["package_size"];
$quantity = $_POST["quantity"];
$search_type = $_POST["search_type"];
$limit = $_POST["limit"];
// Make the Soap Request
$soapClient = new SoapClient($wsdl, $login);
$request =
"<Envelope xmlns='https://schemas.xmlsoap.org/soap/envelope/'>
<Body>
<pharmacies_search xmlns='urn:pharmacies_search'>

</Envelope>";
$err_response = '<?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope SOAP-ENV:encodingStyle="https://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="https://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="https://www.w3.org/2001/XMLSchema" xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="https://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="urn:pharmacies_search"><SOAP-ENV:Body><ns1:pharmacies_searchResponse xmlns:ns1="urn:pharmacies_search"><return xsi:type="SOAP-ENC:Array" SOAP-ENC:arrayType="tns:Pharmacy[0]"></return></ns1:pharmacies_searchResponse></SOAP-ENV:Body></SOAP-ENV:Envelope>';
$location = $wsdl;
$action = "pharmacies_search";
$version = 1;
$response = $soapClient->__doRequest($request, $location, $action, $version);
