SOAP request in PHP with CURL

Php code to soap action via curl:

<?php
$xml = '<?xml version="1.0" encoding="utf-8"?>'.
    '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"'.
    ' xmlns:xsd="http://www.w3.org/2001/XMLSchema"'.
    ' xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">'.
        '<soap:Body>'.
            '<GetShirtInfo xmlns="http://api.soap.website.com/WSDL_SERVICE/">'.
                '<ItemId>15</ItemId>'.
            '</GetShirtInfo>'.
        '</soap:Body>'.
    '</soap:Envelope>';

$url = "https://api.soap.website.com/soap.asmx?wsdl";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

$headers = array();
array_push($headers, "Content-Type: text/xml; charset=utf-8");
array_push($headers, "Accept: text/xml");
array_push($headers, "Cache-Control: no-cache");
array_push($headers, "Pragma: no-cache");
array_push($headers, "SOAPAction: http://api.soap.website.com/WSDL_SERVICE/GetShirtInfo");
if($xml != null) {
    curl_setopt($ch, CURLOPT_POSTFIELDS, "$xml");
    array_push($headers, "Content-Length: " . strlen($xml));
}
curl_setopt($ch, CURLOPT_USERPWD, "user_name:password"); /* If required */
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($ch);
$code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
?>

And output would be like this:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <ShirtInfoResponse
            xmlns="http://api.soap.website.com/WSDL_SERVICE/">
            <ShirtInfo>
                <ItemId>15</ItemId>
                <ItemName>Some Item Name</ItemName>
                <ItemPrice>658.7</ItemPrice>
                <ItemCurrency>AUD</ItemCurrency>
            </ShirtInfo>
        </ShirtInfoResponse>
    </soap:Body>
</soap:Envelope>

Grails withNewSession

Please follow the following scenario:
1. You are saving a domain object 'User'.
2. You are trying to save another domain object 'Activities', indicates that 

   who is saving 'User'.
3. First, 'User' created, so now time to save 'Activities'.
4. But activities failed, what would be the saved user? 'User' would be roll 

   back even if 'Activities' saving between try catch, because of hibernate 

   session?
5. In this scenario you must save your 'Activities' under try catch with 

   'new session', such:

def saveUser = [
    User user = new User(name: "Pritom").save();
    try {
        Activites.withNewSession { sesstion -> 
            new Activities(createdBy: "some name").save();
        }
    } catch (Exception ex) {
        ex.printStackTrace();
    }
}

Now create a html file named 'index.html' such:

    </body>
</html>

Now showing in browser:

In browser they are appearing same. Such original string, after ascii conversion and the back to again string. So why you convert them?

• It is easy to maintain them.
• Easy to insert to and get from database.
• You have no worry about what characters are you inserting to database.
• If you create xml from those data, you do not need to worry about what characters support in xml file, specially when you transport data via api server.

Base64 encode/decode with JAVA

Java code to encode and decode base64

package pritom;

import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;

/**

public class EncodeDecodeBase64 {
    public static void main(String[] args) throws Exception{
        String baseString = "TESTING BASE 64 ENCODING AND DECODING WITH JAVA";
        System.out.println("Base string:     " + baseString);

        /**
         * Encoding to base 64
         */
        BASE64Encoder base64Encoder = new BASE64Encoder();
        String encodedString = base64Encoder.encodeBuffer(baseString.getBytes());
        System.out.print("Encoded base 64: " + encodedString);

        /**

Checking if an element is hidden with jQuery

Html

<form style='display: none'>
<input id='name' type='text' style='display: inline-block' />
</form>

jQuery code

if( $("input#name").is(":visible") ) {
    /* do something, selector is not hidden */
}

This will select the input field and then test correctly whether it is visible in the DOM. This check will make sure all parent elements are visible too, as well as the original CSS display attribute.

Change i18n locale from a controller before calling the view

package pritom.com.locale;

import org.springframework.web.servlet.support.RequestContextUtils as RCU

class FormController {
    def test() {
        Locale locale = new Locale("fr");
        RCU.getLocaleResolver(request).setLocale(request, response, locale);
        render g.message(code: "default.paginate.prev");
    }
}
