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 trying to have a popup with a a nice alert message on my webpage, graying out the background and "OK" button has to be clicked. The page cannot be used until OK, or whatever button is clicked.

Does anyone have a working script for this? I'm assuming it is both CSS and js/jquery.

Thanks much and appreciate it!

We have  a need to track conversions using two Facebook pixels on our ecommerce site.  Would we be ok to include two pixel codes as per below?

<script>
<!-- Facebook Pixel Code -->
  !function(f,b,e,v,n,t,s)
  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?
  n.callMethod.apply(n,arguments):n.queue.push(arguments)};
  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
  n.queue=[];t=b.createElement(e);t.async=!0;
  t.src=v;s=b.getElementsByTagName(e)[0];
  s.parentNode.insertBefore(t,s)}(window, document,'script',
  'https://connect.facebook.net/en_US/fbevents.js');
  fbq('init', '111111111111111');
  fbq('track', 'PageView');
</script>

Hi Expert's,
For remove multiple spaces in a string I use this code: 
$var = preg_replace('/\s+/', ' ',$var);

Open in new window

What changes I have to do in the code, but for remove multiple hyphens?
Examples: this-is---a--test, convert to this-is-a-test;
this is a ---- test, convert to this is a - test;

The best regards,
JC

If you go to this site, https://www.stadriemblems.com in the footer in the bottom right corner, if you hover over the social media icons, they jump all over the place. I can't seem to find anything in the error console that is relevant to this. Is anyone with a better eye than I do able to spot the issue easily?

There is feature is working in the template I'm using but isn't working in my live site.

If you go here to the original template:
https://eagle-themes.com/templates/zante/index2.html
and look at the "OUR AWESOME SERVICES" section, you'll see the feature I'm trying to make work on my live site.

But if you go here to the live site:
https://www.stadriemblems.com/products/enamel-pins-test/
you'll see where I placed it, but it's not displaying properly.

Note that it does seem to be functioning properly, just not displaying any of the css. I figured there must be some external asset that it relies on that is in the original template but is missing from the working site, but all assets from the original template have been carried over to the live site.

I'm going crazy with this. It's probably something really simple, but I have been looking at it too long and can no longer see it.

Hopefully someone can figure this out!

How to customize my WordPress Homepage

I have WordPress and a PowerPress Blubrry plug-in, for my podcast. And thus far, I have only added my logo.

I need to see what options I have to customize the landing page.

Do I need to create a new Page for this? If so, how do I make that page the default?

I want to customize that page using conventional WordPress tools.

Thanks

An employee that took care of hosting the company website was fired yesterday.

We're doing some checking but likely he has the keys to the website hosting account - it's likely using a personal email address of his

I am the domain owner with Godaddy,  The name servers point to the hosting company that hosts the website.

The website is still up, but I would expect he could / will take the site down.

What's the best way to try to download the site at this point?  Again, we don't have access to the account / just FTP all the files as an admin.  I'm thinking we have to do what we can using the public facing part of the website? (I really know nothing about web development, hence this other guy offered and the owners went with him for that).

I remember apps years ago that would just go to www.domain.com, save that page, and go to all the links to pages on that website, downloading each, following links untill they download everything.

The public pages might not be usable depending on the language the page is written in? (ie if a page is written to show today's date for ecxample, the html we download will have todays date. but not the script / code that set it as today?  Open that page tomorrow and it might say today's date?).

But at least we'll have the look and feel of the site.

Hi E's,
I need a Regular Expression because I'm developing an application for banking matters, and in this case, I have to check some tax rate.
The RE just validate if the first character is a number/numbers, a end point, and in the end number/numbers again, like this examples:
0.1
11.45
0.000
0.975

Can you please help me?

The best regards, JC

Hi E's,
I create this regular expression:
"^([0-9\u2098\s]*)$"
The objective is just allow the character M or m, and/or numbers from 0 to 9 (ex: m1; m99, 991, mMM10) , but unfortunately don't work.
What I do wrong?

The best regards,
JC

It did work up until a short while ago, I don't think I made any changes, and the css file is there.

I need to transition to OHV for WordPress

I expect to have some controversial topics on my podcast and hope to use OHV, a provisioning company, instead of a hosting company. But I am not ready to invest $70/month to do this.

https://www.ovh.com/world/

Right now, I am pulling things together using MAMP, but have no plans to purchase the Pro version when it expires. Instead, I hope to host it at a less expensive place when I launch it and get a a solid backup with something like BlogVault, Duplicator or BackupBuddy. I want to move to OHV when I feel the investment pays off.

And, if I get cut off by a hosting provider due to my content, the investment would be worth it immediately.

So, please suggest an inexpensive provider I can start with which has good reliability. I expect to pull thing together on MAMP.

When I buy a plug-in to test on MAMP, is it easy to use it at a hosting provider? I assume there is no licensing issue that would me to purchase a second copy, right?

Thanks.

I am developing an app using Apache Cordova and I have the following code which fails to execute. The idea of the code is:

1) loop through the array with all orders (JSON)
2) retrieve the customer's name
3) generate a table or <tr>

The problem is point 2 - the code just stops and I have to restart the server.
The array with orders is not that big - around 150 JSON objects which I retrieve when the application loads;
the array with customers is even smaller: just two clients are in the array.

Is this an issue with JavaScript concurrency? I would appreciate it if someone can give me an idea of how to tackle this, as I have spent hours trying to figure out how to make this work.

Surely, it must be possible to retrieve the orders - then lookup the customer's name - and then put the data into another array.

Thanks

Massimo

      /**
       * @description retrieves all orders for megamax and genereates table rows for the HTML table
       */
      this.getAllMegamaxOrders = function () {
        "use strict";
        var mm_orderID = 0;
        var mm_customer_id = "0";
        var mm_orderDate = "";
        var mm_customerName = "";
        var mm_lat = "";
        var mm_lng = "";
        var mm_price = "";
      
        
        //loop through all orders from array allOrders
        for (i = 0; i < app.allOrders.length; i++) {

          //populate local variables
          mm_orderID = app.allOrders[i].id;
          mm_customer_id =

Hi

I'm trying to create an online shop. Because of that I need a payment provider.
What would you recommend me?

I'm confused with so much providers like PayPal, Amazon Pay, Sofortüberweisung etc.

Thank you in advance

Cloning my Chrome Bookmarks?

I have a Windows 10 PC and a Windows 10 Virtual Machine and would like to keep the bookmarks in sync between the two.

At the moment, when I need something, I switch back to my desktop for the URL and copy it to Chrome on my VM.

Is there a way to handle this where they stay in sync? If not, must I export a file then import that file?

Thanks

So I buld dynamic websites. As CMS I use something I have built by myself because I wanted to offer something very simple and easy to use to my client: they are small clent and they can't spend time to learn how to use Wordpress, OpenCart or other complex CMS. They just have to add, delete and modify some products data, or even just add some news to publish in the homepage.
So I have developed my own CMS. My problem is that I always work on it to improve it and everytime I change somewthing I have to manually upload changed files to the clients websites in order to always be sure I have the same code running in the various Control Panels.

As you guess, this becomes soon a crazy task, subject to errors and confusion. I would like to automate this process but I'm not sure how to do it.

Let me say that the develpment version of the code uses Git as Version control system. I also have to specify that between the various versions of the Control Panel, only one file is specific to that specific client, a configuration file in json format which my classes read to do the various tasks.

This config files holds specific settings and many times, as I improve the doce and some new features, the config file itself needs to be changed and I have some doubt this can be automated because here I need to preserve orginal specifi settings whil I add new sections with new settings and their default values.

So I think I could manually update only this file, but how can I make the …

I wrote a CGI in perl a long ago (never wrote perl script for ten years ;-). It is  named "check.cgi" in the www/cgi-bin directory (i.e. www/cgi-bin/check.cgi)

It starts as follows:

#!/usr/bin/perl
use strict;
use CGI;
our $mailprog        = "/usr/sbin/sendmail -t";
our $respond         = "";
our $upto            = "";
our $data            = '';
our $db              = '';

# -----------------------------------------------------------------------------
# declare base
# -----------------------------------------------------------------------------
our @token;
our $q  = new CGI;
our %in = $q->Vars;
our %gp;

# -----------------------------------------------------------------------------
# get the inputs
# -----------------------------------------------------------------------------
our $dn       =lc($in{'dn'       }) || ''         ;
our $orig     =lc($in{'orig'     }) || ''         ;
our $tld      =lc($in{'tld'      }) || ''         ;

Which URL should be entered to trigger it : "http://abc.de/...."  what the "...." should be ?

Thanks a lot !

Where to place the <script> tag on the HTML page?

I know there are different places you can put this, depending on the behavior you want and also depending on the type of scripts you need to load.

So, what are the different places on theHTML page and what factors govern your decision? And are these script always Javascript?

Thanks

I'm working on https://renalmeals.com. I used Google Chrome audit on it. One of the things it recommends is:
"For stylesheets, consider splitting up your styles into different files, organized by media query, and then adding a media attribute to each stylesheet link. When loading a page, the browser only blocks the first paint to retrieve the stylesheets that match the user's device. See Render-Blocking CSS to learn more. Build tools like critical can help you extract and inline critical CSS."

I'm pretty new at npm. No, I'm VERY new at NPM. I managed to install it using $ npm i -D critical@latest. Now I want to do this, below.  And I'm stumped. Can someone give me more specific instructions? Thanks!

Generate and inline critical-path CSS
Basic usage:

critical.generate({
  inline: true,
  base: 'test/',
  src: 'index.html',
  target: 'index-critical.html',
  width: 1300,
  height: 900,
});
