jQuery code

var createAllErrors = function() {
    var form = $( this ), errorList = $( "ul.errorMessages", form);
    var showAllErrorMessages = function() {
        errorList.empty();
        
        // Find all invalid fields within the form.
        var invalidFields = form.find( ":invalid" ).each( function( index, node ) {
            // Find the field's corresponding label
            var label = $( "label[for=" + node.id + "] ").html();
            if(label === undefined) {
                label = "";
            }
            // Opera incorrectly does not fill the validationMessage property.
            var message = node.validationMessage || 'Invalid value.';
            errorList.append( "<li><span>" + label + "</span> " + message + "</li>" );

Using php download a temporary file

<?php
$dataArray = array(
    "name" => "Pritom K Mondal",
    "company" => "Some Company"
);
$tmpName = tempnam(sys_get_temp_dir(), 'data');

$tmpFile = fopen($tmpName, 'w');
fputcsv($tmpFile, $dataArray);

header('Content-Description: File Transfer');
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename=download.csv');
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($tmpName));

ob_clean();
flush();
readfile($tmpName);
unlink($tmpName);
?>

Using java copy array using copyOf

byte[] src = {1, 2, 3, 4};
byte[] dst = Arrays.copyOf(src, src.length);
System.out.println(Arrays.toString(dst));

Grails, finding available views (.gsp's) at runtime

This is not a important post. I just need to do some googling to achieve this and i found at: http://stackoverflow.com/questions/1577872/grails-finding-available-views-gsps-at-runtime. Thanks Burt Beckwith. I put this here to not search in google again.

import org.codehaus.groovy.grails.web.context.ServletContextHolder as SCH

def viewGsp() {
    List gspFileList = []
    if (grailsApplication.isWarDeployed()) {
        findWarGspList ('/WEB-INF/grails-app/views', gspFileList);
    } else {
        findDevGspList ('grails-app/views', gspFileList);
    }
    gspFileList.each {
        render it.toString() + "<br/>";
    }
    render "";
}
private void findDevGspList(String location, List gspFileList) {
    for (file in new File(location).listFiles()) {
        if (file.path.endsWith('.gsp')) {
            gspFileList << file.path - 'grails-app/views/';
        } else {
            findDevGspList (file.path, gspFileList);
        }
    }
}

private void findWarGspList(String location, List gspFileList) {
    def servletContext = SCH.servletContext
    for (path in servletContext.getResourcePaths(location)) {
        if (path.endsWith('.gsp')) {
            gspFileList << path - '/WEB-INF/grails-app/views/';
        } else {
            findWarGspList (path, gspFileList);
        }
    }
}

Hibernate/grails left join or inner join when using create criteria

Hibernate/grails left join or inner join or join when using create criteria. If you do not use

'CriteriaSpecification.LEFT_JOIN', then it would be a inner join. 

Here is the example as suppose 'User' belongsTo 'Role' which is nullable.

Now you want to left join 'Role' when creating criteria on 'User', then do 

the following. It would take all 'User' row where 'Role' is null or not.

But if you do not use 'CriteriaSpecification.LEFT_JOIN', then it would take only

'User.role' is not null. 

import org.hibernate.criterion.CriteriaSpecification;

List userList = User.createCriteria().list {
    eq("isActive", true);
    createAlias("role", "__role", CriteriaSpecification.LEFT_JOIN)
    eq("__role.someProperty", "some value");
}

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();
    }
}
