Hello guys, please can someone explain to me how i can know the framework of any website on the internet. I know how i can detect wordpress but other framework are hard for me. Please i need assistance on this.

I want to understand how I can add an SDK to my PHP projects to make APIs calls. I noticed that every software company have an SDK. I also noticed that most SDKs use Composer. I don't know what composer is and do I need to have it for every SDK?

I am also using PHP procedural programming and I noticed that these SDKs use OOP.

Can someone help me make my first API call using an SDK?

Hello,

I am somewhat new to APIs. I have integrated PayPal payments successfully. With PayPal, I can send the user to the payment page using an HTML form. Here is an example ...

<!-- PAYPAL -->
<form action="https://www.paypal.com/cgi-bin/webscr" method="POST" name="_cart">
    <input type="hidden" name="cmd" value="_cart" />
    <input type="hidden" name="upload" value="1" />
    <input type="hidden" name="no_shipping" value="1" />
    <input type="hidden" name="business" value="" />
    <input type="hidden" name="currency_code" value="USD" />
    <input type="hidden" name="item_name_1" value="" />
    <input type="hidden" name="amount_1" id="amount" value="1.00" />
    <input type="hidden" name="custom" value="" />
    <input type="hidden" name="return" value="" />
    <input type='hidden' name='notify_url' value="">
    <input type="hidden" name="cancel_return" value="" />
    <input type="submit" class="submit" value="Deposit Money Via PayPal">
</form>
<!-- PAYPAL -->

I want to do the same thing for AirTM. Here is their developer page: https://docs.airtm.com/purchases-payins/create-purchase

I am not sure where to include the Header information.

Can you help?

Hello webmasters,

I am currently building a template that I am going to sell on different websites like Codester and CodeGrape.
I want to build a business directory.

Here is what I have come up with ...

1. users can register and add listings.
2. admin can create categories for users to select from.
3. admin can create sub categories if necessary.
4. users can submit a review for listings ranging from 1 to 5 stars with comments.
5. users can buy a featured listings for more traffic.
6. admin can set listings parameters like website url and email address or phone number.

What else should I include?
I am not sure if I am missing something important.
Any suggestions?

About a year ago, I had a similar issue except then system would crash after pressing Submit. The issue was caused because of PHP 8 incompatibility problems. However, got the coding to fix all of that and things worked good again and with PHP 8. But now something new is happening. Now, when Submit is pressed, system doesn't crash and goes to the after submission screen like its supposed to. Everything appears to be working fine except for one thing. No emails are being received. Last on line submission form I received was on 2/6/2024. No coding was changed at all, just nothing sends at all. I tested multiple on line submission forms on several websites. Same thing, nothing is sending. The coding I used to fix everything before is the same on all the on-line submission pages. It appears to be an issue with PHP. The coding for 1 of these pages is below.
`

<?php
// grab recaptcha library
// require_once "recaptchalib.php";
// foreach ($_POST as $key => $value) {
    //echo '<p><strong>' . $key.':</strong> '.$value.'</p>';
  //}
// your secret key
$recaptcha_secret_key = "6LeW4RQUAAAAAJ4NvgWIKJc4b-AeKp6LcLFCFQoS";

// empty response
$recaptcha_response = $_POST['g-recaptcha-response'];

$recaptcha_url = 'https://www.google.com/recaptcha/api/siteverify';
$recaptcha_data = array(
    'secret' => $recaptcha_secret_key,
    'response' => $recaptcha_response
);

$recaptcha_options = array(
    'http' => array(
        'header' => "Content-type: application/x-www-form-urlencoded\r\n",
        'method' => 'POST',
        'content' => http_build_query($recaptcha_data)
    )
);

$recaptcha_context = stream_context_create($recaptcha_options);
$recaptcha_result = file_get_contents($recaptcha_url, false, $recaptcha_context);
$recaptcha_json = json_decode($recaptcha_result);

if ($recaptcha_json->success) {
    // ReCaptcha validation successful, process the form submission
    // Your form processing code goes here

$subject = "Showing Scheduling";
$message = "RadiantNewHorizonHomes.com Showing Scheduling" . "\r\n" . "\r\n" .

$from = $_POST['ShowingEmail'];
$headers = "From: $from" . "\r\n";

$to = "david.tigner@radiantnewhorizonhomes.com";
mail($to,$subject,$message,$headers);
$to = "Agents1@radiantnewhorizonhomes.com";
mail($to,$subject,$message,$headers);

} else {
    // ReCaptcha validation failed, display an error message or take appropriate action
    // Example: redirect back to the form page with an error message
    header('Location: form.php?error=recaptcha');
    exit();
}   

?>

I think that I understand the difference between:

document.addEventListener('DOMContentLoaded', callback_fn);

and:

window.addEventListener('load', (event) => { ... });

However, as a jQuery user, what is the difference between DOMContentLoaded and the jQuery ready fn?

I have problem with this htaccess in STATIC URL

RewriteEngine On    
RewriteRule ^readlex/(.*)$/?$          readlex.php?slug=$1 [NC,L]

DINAMIC URL work fine only with defined CONSTANT: Example

<a href="<?php echo BASE_URL.READ_LEX ?>Le-mura-di-Lucca">Lucca</a>

Result = localhost/mysite/readlex/Le-mura-di-Lucca

STATIC URL not work (??)

<a href="localhost/mysite/readlex.php?slug=Le-mura-di-Lucca">Lucca</a>

Result = localhost/mysite/readlex.php?slug=Le-mura-di-Lucca">Lucca

***Unfortunately I can't insert the php CONSTANTS in mysql varchar/text

What was wrong with good ole using SMTP?

Has anyone here successfully used an XOAuth library for PHP? Specifically, I'm looking to connect to my Office 365 mailbox.

The error message I've encountered is; ERROR:root:Error generating model response: exception: access violation writing 0x0000000000005140, which seems to be indicative of an access violation exception that occurred within my application. This type of error apparently usually points to a problem where the code attempted to write to a protected memory address it does not have permission to access!?

I am attempting to create an interactive web application In Python Flask where users can input text and receive responses generated by a machine learning model, specifically using a model from gpt4all. The application uses Flask, a Python web framework, for the backend, and jQuery for the frontend to handle user interactions. Here's a breakdown of how they function together

Integration and Functionality The frontend sends user input to the backend via AJAX, ensuring a smooth, asynchronous interaction without needing to reload the page. The backend receives this input, processes it through the machine learning model, and sends back a generated response. The frontend then displays this response to the user in the #responseBox. At least that's my intend!

The Codes that produces the issue is somewhere in the below text, which I seem to not be able to find and correct, advice is highly appreciated:
Chatbox.py file: from flask import Flask, render_template, request, jsonify import logging from gpt4all import GPT4All

app = Flask(name)

Load the model name from an environment variable or default to a specific model
model = GPT4All('nous-hermes-llama2-13b.Q4_0.gguf')

logging.basicConfig(level=logging.INFO)

@app.route('/') def index(): return render_template('index.html')

def make_request(user_input): logging.info(f"Received user input: {user_input}") # Log the received input try: with model.chat_session('You are a geography expert.\nBe terse.', '### Instruction:\n{0}\n### Response:\n') as session: response = session.generate(user_input, temp=0) return response except Exception as e: logging.error(f"Error generating model response:'{user_input}': {e}") return "Error processing your request."

@app.route('/chat', methods=['POST']) def chat(): user_input = request.form.get('inputPrompt') response = make_request(user_input) return jsonify({"response": response})

if name == 'main': app.run(debug=True)

In html file:

$(document).ready(function(){ $('#enterButton').click(function(){ var user_input = $('#inputPrompt').val(); $.post('/chat', {inputPrompt: user_input}, function(data){ var response = $('#responseBox').html(data); $('#inputPrompt').val(''); // Clear input box after sending the message }); }); });
I have been struggling with finding the problem and thus the solution to the issue. I'm a new, as green as can be, so please be gentle and pardon me for my ignorance on the matter. I've had a hard time with the issue and simply cant figure it out. All help and advice would be much appreciated. thank you in advance.

I, very hackily, create an object of type stdClass as so:

$arr = array(
    'foo' => 'bar',
    'baz' => 'bat'
);

$obj = json_decode(json_encode($arr));

How can I now quickly add a third property to $obj without PHP getting angry?

Hi, Goodday everyone, I'm new to web development, please if I had questions, could I ask on her for a help reply?

Hello I am trying to query a database to show records only for the current user using variable I get the correct data but only 1 row with results any guidance?

// Query database to retrieve records associated with the user

I am trying to create a meme generator similar to imgflip.com
I know javascript but not sure how to implement this.
I want users to be able to move text around the canvas using mousemove event listener.
But I am not sure if they are moving the text on the canvas or are they creating an overlay div then transform the dimension's to canvas?

I'm using Elementor Pro to build my website, including a custom header design. However, when the same header is applied to a page built with the Kadence theme (specifically the blog page), the design breaks down.

What settings or configurations within Elementor Pro might be causing the mismatch?

I felt uninspired for a spell in 2019 and decided to enroll in a beginning-level community college course on web development as a way to “spice” things up, sort of like going backwards in order to move forwards. I had no interest in being an old dog learning new tricks; what I wanted was to look at front-end development through the eyes of a beginner in 2019 after having been a beginner in 2003.

Fast-forward five years, and I’m now teaching that class for the same college, as well as three others. What I gained by reprising my student status is an obsession with “a-ha!” moments. It’s the look in a student’s eyes when something “clicks” and new knowledge is developed. With the barrier to learning web development seemingly getting higher all the time, here I am, making merry with the basics. (That linked post to Rachel’s blog is what spurred me to go back to school.)

With several years of teaching under my belt, I have plenty of opinions about the learning landscape for web development. But what I am more interested in continues to be vicarious living through the eyes of my entry-level students and the consistent sparks of knowledge they make.

Questions are often the precursor to an “a-ha!” moment. And my students ask some pretty darn interesting questions every term, without fail, questions that have forced me to reconsider not only how I approach curriculum and instruction but also how other people think about The Web™ as a whole.

I’ve made a practice of collecting handfuls of student questions and comments. That way, I can reflect on how I might respond or answer them for future students and reference them as I write and update my lesson plans. I thought I’d share a few of them because, I hope, it will give you an idea of what those getting into the field are curious about. I think you’ll find that as many of us debate and decry the value of JavaScript frameworks, Core Web Vitals, AI, and whether Typescript is a necessary evil, the people cracking into web development are asking the most interesting questions in the field and are making way different connections than those of us who have spent forever on the front end.

These are pulled straight from students in the current Spring term. We’re only three weeks into the semester, but check out what sorts of things are already swirling around their minds as we discuss semantics, accessibility, and writing modes.

“I really never thought of this; however, code could be inclusive, and how coding could express empathy. While reading this portion of the context, I was thinking about my Kindle and how the Kindle can have audio, change my font style, larger/smaller font, and lighting. All of this helps me to read and navigate my books better depending on my surroundings and how much accessibility I will need. For example, when I am driving, I love my audiobooks, and at night, I use my dim setting and change font size because it’s the end of the day, and my eyes don’t want to do too much work reading smaller text. It’s really fascinating that coding can do all of this.”

“If we are confused about our coding and it doesn’t make sense to us, it will definitely confuse the readers, which is the opposite of our end goal, accessibility. There are also times when we might want to use <div> where we could use <article> or <nav> or any of the other important elements. It’s essential to fully understand the elements and their uses in order to write the cleanest code.”

“Tackling CSS logical properties this week felt like a juggling act, trying to keep all those new concepts in the air. Swapping left and right for inline-start and inline-end is a bit confusing, but it’s cool to see how it makes websites more welcoming for different languages.”

“What are the legal implications of website liability? I couldn’t imagine the size of a class action lawsuit that Facebook would get smacked with if a rogue developer decided to pin a gif of a strobe light to the top of the world’s newsfeeds. Are websites subject to the same legislation that requires buildings to have wheelchair ramps?”

“Sometimes, I wonder how to make all this new stuff work on old browsers that might not get what I’m trying to do. I also get stuck when my page looks great in one language but breaks in another. What’s the best way to check my work in different languages or writing modes?”

“One of the big things that really got me stoked was learning how to make content in Flexbox the same size using flex or flex-basis. This was a really big thing for me last semester when I was working on my final project. I spent a lot of time trying to figure out how to make the content in Webflow equal in size.”

“Hearing the terms “Writing Modes” and “Logical Properties” in CSS was a bit of a concern at the beginning of this week. A lot of CSS I remember was beginning to come back, but these two were new. After going over the course modules, my concern lifted a lot, mainly because Writing Modes were the layout of text in a certain element. As simple as I thought it was, it was also very important considering how writing modes change in different countries. Learning how these writing modes change the flow of text showed how much more inclusion you could bring to a website, allowing for different languages to be filtered in.”

“Although in the previous course, we learned how flexbox and grid can be used to style interesting content on sites, we didn’t study how they were made with CSS. It was surprisingly simple to grasp the basic concepts of setting up a flexbox or grid and how their children can be positioned on a main axis and cross axis. I especially enjoyed setting up grids, as both methods are intuitive, and the concept of selecting the grid lines that an element sits in reminds me of how some programming languages implement arrays and ranges. Python, for instance, allows the user to select the last element of an array using -1 just as the grid-column: 1/-1; the property can specify that an element spans until the end of a row.”

“Logical Properties were intimidating at first, but it was just changing the code to make it make sense in a way. After learning CSS — a bit a while ago — Logical Properties seemed more modern, and I think I adapted to it quickly.”

“But as a whole, I could see the building of websites to be a very easy thing to automate, especially in this day and age. Perhaps that is why site builders do not get super specific with their semantics — I usually only find <html>, <body>, and <head>, while the rest is filled with <div>. Especially when it comes to companies that push a lot of articles or pages out onto the internet, I can see how they would not care much for being all-inclusive, as it matters more that they get the content out quickly.”

“I did not think I would enjoy coding, but so far, I like this class, and I’m learning so much. I liked getting into CSS a little and making things more customizable. I found it interesting that two elements make your content look the same but have different meanings.”

I want to end things with a few choice quotes from students who completed my course in the last term. I share them not as ego boosters but as a reminder that simplicity is still alive, well, and good on the web. While many new developers feel pressured to earn their “full stack” merit badge, the best way to learn the web — and make people excited about it — is still the simple “a-ha!” moment that happens when someone combines HTML with CSS for the first time in a static file.

“I can confidently say that among all the courses I’ve taken, this is the first one where I thoroughly read all the content and watched all the videos in detail because it is so well-structured. Despite the complexity of the subject, you made this course seem surprisingly easy to grasp.”

“Man, I’ve learned so much in this class this semester, and it’s finally over. This final project has given me more confidence and ability to troubleshoot and achieve my vision.”

“Even though I did not pass, I still truly did enjoy your class. It made me feel smart because coding had felt like an impossible task before.”

“I especially appreciate Geoff’s enthusiasm for multiple reasons. I am hoping to change careers, and the classes are helping me get closer to that reality.”

These are new people entering the field for the first time who are armed with a solid understanding of the basics and a level of curiosity and excitement that easily could clear the height of Mount Elbert.

Isn’t that what we want? What would the web look like if we treat the next wave of web developers like first-class citizens by lowering the barriers to entry and rolling out the red carpet for them to crack into a career in front-end? The web is still a big place, and there is room for everyone to find their own groove. Some things tend to flourish when we democratize them, and many of us experienced that first-hand when we first sat down and wrote HTML for the very first time without the benefit of organized courses, bootcamps, YouTube channels, or frameworks to lean on. The same magic that sparked us is still there to spark others after all this time, even if we fail to see it.

I'm facing an SSL-related issue in Firefox with the 'SSL_ERROR_NO_CYPHER_OVERLAP' error. It seems there's a problem with encryption algorithms between the browser and the server, hindering the establishment of a secure connection. Any guidance or solutions would be appreciated.

hai. i would like to know is there have any video that can teach how to import image from database image folder to pdf using fpdf php. i already read some post here regarding to that issue by im not very clear and blur. actually i am very new in coding.

hope that anyone can help.
