Web Languages and Standards





Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services using a wide variety of languages and standards, including the familiar HTML, JavaScript and jQuery, ASP and ASP.NET, PHP, ColdFusion, CSS, PHP, Flex and Flash, but also the implementation of a broad list of standards including XML, WSDL, SSDL, VoiceXML and many more.

I am looking for a free or paid software in order to build database/table/api schema among my various production, testing environments.
I tried yEd but it is not very practical for me.
Could you please advice on this.
Thank you very much in advance for your feedback.

Hi everybody.
I really don't understand how to change the overlay background color in this template: https://colorlib.com/preview/#amado.
I mean: if you hover the mouse on products, a dark semi-transparent overlay appears. The template uses a scss file. In the index a fiola called style.css is linked, but that file is empty and with developer tools I see all styles are set in  style.scss, but I'm not able to find the value that I have to change. I confess I'm totally new to sass, scss.
I post here the scss file:
@import 'theme_color';
@import 'variables';
@import 'mixin';
@import 'responsive';

are there any tools to audit a website and all its sub pages to identify those where users can submit content, e.g. 'contact us' type forms? We need to create an inventory from a site that wasnt put together internally to ensure we know what data is being submitted and to where, but the site is fairly badly constructed so if there was an automated way of doing so that would be a great help. I didnt know if it could look for the code and submit type syntax? Or any other clever ways of acheiving the same.

Hi E's,
I want overlay two images in a responsive project. That not easy when we working with CSS position relative.
So, because that, for overlay two images, one will be a background-image, and other is a normal image inside the div, like you can view here:
<div class="row" style="margin-top: 200px;">
        <div class="col s10 l4 offset-s1 offset-l4" id="fundo" style="background-image: url(imagem/MVC-610X.JPG); max-width: 1024px; max-height: 768px;">
        <img src="imagem/MVC-611X.JPG" class="responsive-img" alt="" style="opacity: 0.5">

Open in new window

With the above code, I can overlay two images (background and div).
I try to found a solution for animate the background image to opacity 0.
With follow code, I try a solution, but all the elements set to opacity 0, include the image inside the div:
$('#fundo').animate({"opacity": 0}, 5000 );

Open in new window

I know the reason why all the elements set to opacity 0, I try to search a solution in the Internet, and I don't find anything related, so I come to EE's to try to get a solution for:
How I create a Jquery animation from opacity 1 to opacity 0, just for the background image, preserve the image in the div?

I want to invalidate my form using jQuery/Javascript.

User enters date field (having id# vhdnPickUpDate) and time field (having id# vPickUpTime)

User should not be able to submit the form if date time is less than 4 hrs which user has entered.

Current time is in field hdnDateTime from where date time needs to compare.

I need to know the logic for this.
How to invalidate the form if datetime is less than or equal to 4 hrs.
Also, accordingly date field needs to be highlighted.

Kindly advise me the solution.

Below is the logic required and details.

var form = $("form");

hdnDateTime= "04/08/2018 07:30:00"


vPickUpTime="5:30 AM"

var dtTime = vhdnPickUpDate +" "+ vPickUpTime=;
var dtTimeMinus4Hrs = dtTime - 4 hrs;

if(hdnDateTime <= dtTimeMinus4Hrs)

invalidate form
Highlight field with id = Item_PickUpDate
// Kindly advise me the solution

if (form.valid()) {

Hi Experts

Could you point if  phpCAS that uses API for authenticating users against a CAS server (WebSSO CAS) could be integrated at an existing Codeigniter project?

CAS - Central Authentication Server

I'm implementing a SSO (Single Sign-On)  funcionality to allow a web app conexion based on user id and  correspondent user's data obtained from LDAP (AD-Active Directory)


I'm planning to implement the SSO functionality at PHP Codeigniter's site index.php.

Thanks in advance!
Hi E's, I just want to known if my file robots.txt is well written.
The objective is allow all my pages, but disallow 12 url's, for all agents:
User-agent: *
Disallow: /comprar-zara
Disallow: /politica-de-privacidade
Disallow: /comprar-zara-lisboa
Disallow: /melhores-saldos-2018-lisboa
Disallow: /temas/viagem
Disallow: /temas/compras
Disallow: /temas/compras-saldos
Disallow: /temas/viagem-portugal

Disallow: /cremes-para-quase-tudo
Disallow: /temas/saude-cremes-de-beleza
Disallow: /temas/moda-compras-e-saldos
Allow: /

The big question is, the "Allow: /" should be at the top or bottom?

I am gearing up to a new role here at work... I've been the main IT guy for 17 years, and in the first few of those years I did quite a bit of PHP coding for our website. Since that time, we've grown a lot and have had a full time backend web developer (leaving the company in October) who is a wizard with PHP, MySql, Symfony. Those are the core MVC languages we use in the backend... our front end person uses Twig, React, etc but I won't have to do much with that except pass her data she can display whoever she wants.

Where are a couple good courses I can take to get up to speed with PHP these days? From working with our existing backend guy, he's walking me through Symfony a lot but I've notice he is hand-coding a ton of PHP / MySQL stuff and I realized that is where I need to concentrate learning right now. Any good resources out there, or is Udemy the end all be all. If so, which Udemy course most applies to my needs. Thanks much for any input.
How to read Child tags under parent tag with name space in C#?
<ns:tag1></ns tag1>

How to read child 1 tag?
I am able to till ns:tag2 but unable to read any further tag.
var child = parentElement.Descendants(ns + "tags").First();
This provides list of child tags, but unable to further read it.
Tried a few things like:
and child.Element("child1") (with all possible sub functions)
Even tried to reload the xml from tag2 in XElement again but that threw invalid xml exception.
but all are throwing null pointer exceptions.

In a meeting we were told that it is possible to know or identify if a user hit a specific page and it’s contents even if the page is locked.  We understand that when a page has a lock it means SSL and that the data to/fro from the site to computer is encrypted.  Is this possible that even thought the page has a lock, there is  a way to identify the encrypted page that the user visited and identify the contents, if it has form or just regular page?
hi there,

Currently I'm trying to create, sign & broadcast bitcoin transaction using btcsuite. For start, I've already had testnet3 address & its associated privatekey for testing. However, hunting through the post and articles like below:-


The solution proposed above its not complete, for first one, it only covers until signing (i knew the author claimed its not broadcastable unless you provide the utxo which i did if i'm right) but when tried to braodcast it failed with message

"Error validating transaction: Transaction be9b294695bfb201a5cff32af074a4bf72b073e3c9dad1969111165bf118a622 orphaned, missing reference f0c0d3b3eecf911ede996a74ceadc9366068791450c9e6bacee9ae202f3690d1."

I have no idea what's going on and I suspect its script is incompatible.

So, the bottom line is I just want a workable example in bitcoin testnet3 that shows "from 1 address transfer some bitcoin to other address" by showing the process of creating raw transaction, sign it with private key, turn it to raw transaction in hex format & broadcast it using something like https://live.blockcypher.com/btc/pushtx/ (BTC testnet)

currently my code is as follow:-

I am exploring xml and am trying to write nested XML elements like this in Windows Powershell:






I am completely new to writing XML as well as using powershell, so if you can keep the training wheels on with your explanation/example, I would greatly appreciate it.


I need to write this code in global.asa. GetLastDateandTime is working fine. I need to put that in the session. If user is present then we get the data from the database. This function is working fine. If user is not present then we are using update function. My update function is not working. Page is down. I am not sure how to fix the update function.

Hi Experts,

Could any one tell me what does testing a website to be compliant with WCAG 2.0 Level A and AA involve?

Are there any curses for this?

What is the going rate for this?

I'm also wondering, what are the types of assistive devices covered, so that I can recruit the right persons with disabilities (myself included ), and what to test for. The client is asking for testers with disabilities.

Thank you.

Dear Experts,

I have an asp.net website that uses identity 2.1 (I'm pretty sure > 2.0 anyways as near as I can tell). It is written in visual basic. I ran into a weird issue the other day where people were logging in and getting this viewstate error:

Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

So I followed the advice I found in the microsoft article and added a machine key to the web.config file so that no matter what it (hopefully) shouldn't get that error again.

Once the machine key was changed to one that I set now we had issues with anyone with an already existant authorization cookie on their computer, they were unable to login. I believe it's because the machine key that I set no longer matched the one that was used in their cookie. I'm not entirely clear how, but apparently it's part of how it's encrypted. If they clear their cookies, all is well - then they could login.

So one bit of advice I found searching on the web sounded super simple and super-easy. They recommended that you have some sort of set key in your web.config, like a guid or something and then you add it to your cookie also. Then, when you load the cookie, you can check the key and if it doesn't match your server key, somehow you invalidate the cookie.

I basically spent all day trying to figure out …

I was looking for some guidance on the approach to a specific user experience and how people would approach it or if someone has done something like this already.

I have a simple PHP script that enters a value from a text box into the database when the 'add' button is clicked or the user hits enter after entering a value (script below).

What I would like to do is allow a user to hit the enter key when they add their record (as it works below), but if the user were to hit the enter key again, within 4 seconds, it would bring up the full record that they could edit. It is because sometimes the user will only add the one value, but sometimes they will add the one value and also want to view and edit some other fields for that record - how would others approach this from a scripting perspective and also side topic on the User Experience side; are there better ways to do this?

$form = "<form action='./dash_hit46.php' method='post'>" .PHP_EOL;
$form .="<input type='text' id='newadd' name='newadd' placeholder='e.g. x'>" .PHP_EOL;
$form .="<input type='submit' value='add' name='add'>" .PHP_EOL;
$form .="</form>";

if ($_POST['add']){
	$newadd = $_POST['newadd'];
		if ($newadd){

		// Check connection
if ($conn_task2->connect_error) {
    die("Connection failed: " . $conn_task2->connect_error);

$sql = "INSERT INTO main (tsk_name, tsk_person, tsk_user_link)

Looking for best advice on how to redirect my page after the user had logged into the site.

I have a PHP form which is using the POST method to submit the details to the login page (called login.php) and connects to the mySQL database to authenticate. If the user successfully has entered the right information I have a link that will move them into a members page - i do this process via an IF....Else statement.

Instead of getting the user to actively click on then link to move them on, how would it best be done to automatically redirect the user to the next page (i.e., dashboard.php)? I was looking at the PHP header() function and a JavaScript window.location.replace option - wanted to get some opinions on here too on the simplest, universal way to do this?

Open to any options/suggestions; doesnt have to be PHP or JavaScript.

Thanks in advance.
In my Magento there is an exception message "The requested Payment Method is not available." from Mage_Core_Exception class happening on a few pages:
  • /checkout/onepage/saveShippingMethod/
  • /checkout/onepage/

This is the stacktrace:
The version is Magento CE
What is the issue and how to fix this?
I am migrating a Magento 1 module to be used on the Magento 2 platform.  All of the code has been migrated and produces the expected results but in Magento's technical review process it fails the varnish check.Capture.PNGMy initial research into the issue shows that you should specify cachable=false on your block elements or by setting the _isScopePrivate property in your defined Block PHP file.  The only problem is that I do not have any block elements.

I have created one to try and combat this issue but the module does not require any block elements.  The module works by appending the quote results to a rateResultFactory which is then displayed on the Checkout screen.

I have also tried to use the method described here to try and retrieve any dynamic data without requiring the cacheable flag.

Any help would be tremendously appreciated.

Need to have a "copy to clipboard" feature on my News Articles

I like the site at the company with which I am partnered...but want to be sure I am as little like their site as possible.

Here is the feature in question...

To the right of the article is an icon.

Icon Only
When you click the icon, three choices display themselves.

I only use the "Copy Link" feature

Copy Link
Which opens this box...

Copy Link 2
I want to be sure this feature exists on my website, partly so I can use it to send to articles to clients and so can my sales agents. Obviously, there will be a page label in the URL so that URL opens not only the right page, but to the part of the page where the article is visible.

What similar thing can you show me from some other site? I do not want to copy my partner's site. So, I am taking out the LinkedIn and Email features. I just want that URL in the clipboard.

I know this has been part of the web standard since forever. But I just need to see one example of it some where.

Given this (admittedly awkward) sentence:

We have been over this - I mean Brian and I, not you and I - in the past.

Is it supposed to be "Brian and I" and "you and I", or should it be "Brian and me" and "you and me"?
