I’m working on a Laravel application that needs to handle CORS for requests coming from a Vue 3 frontend. I am encountering a CORS error related to credentials, and I need help configuring CORS correctly in my Laravel backend.

I receive the following error when trying to make an XMLHttpRequest from my Vue application to my Laravel backend:

Access to XMLHttpRequest at 'http://127.0.0.1:8000/api/oauth/token' from origin 'http://127.0.0.1:5173' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The value of the 'Access-Control-Allow-Credentials' header in the response is '' which must be 'true' when the request's credentials mode is 'include'.

With sylius 1.13 i wan’t to override AvailableProductOptionValuesResolver.php

I’ve copied the original class in src/Component/Product/Resolver/AvailableProductOptionValuesResolver.php

and change the namespace and add debug:

<?php

namespace AppComponentProductResolver;
class AvailableProductOptionValuesResolver implements AvailableProductOptionValuesResolverInterface
{
    public function resolve(ProductInterface $product, ProductOptionInterface $productOption): Collection
    {
        dd('modify');

What other changes need to be made for this class to be used? Because here it’s always the file in /vendor/…/AvailableProductOptionValuesResolver that’s used.

$socket = socket_create(AF_INET6, SOCK_RAW, 58);
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, array('sec' => 1, 'usec' => 0));
$type = chr(135);
$code = chr(0);
$check = chr(0);
$check .= chr(0);

$reserverd = chr(0) . chr(0) . chr(0) . chr(0);
$distMul = "ff02::1:ff26:13dc"; //solicitation node multicast address
$target = "fe80::3b40:f032:5726:13dc";
$id = inet_pton($target);
socket_set_option($socket, IPPROTO_IPV6, IPV6_MULTICAST_HOPS, 255);
$package = $type . $code . $check . $reserverd . $id;
socket_connect($socket, $distMul, 0);
socket_send($socket, $package, strlen($package), 0);
$str = socket_read($socket, 2048);
socket_close($socket);

Above is a script to send ICMPv6 solicitation request.
here is Wireshark capture.

the problem is , the request never get any reply, according to the IPV6 doc, the script should get a “Neighbor Advertisement (Type 136)” reply, but this is not happening.

I have VS Code installed on my client (laptop).

PHP is installed on the server. However, since its shared hosting, I can’t install anything myself (like Xdebug). Is possible to debug PHP (set breakpoints, step through code)? For example, can I use the Interactive PHP Debugger?

NuSphere PhpED IDE says that the debugger works with shared hosting. I found a tutorial on how to set it up. I’m hoping the same can be done with VS Code.

So I created a page where the details a product can be stored.
Here is how it works:

1. When the window loads 2 IDs are created (ABC and DEF).
2. The user can insert any data and values in the site.
3. After that they can click “SEND”.
4. After clicking that button, there is a table in mySql named ‘Details’ where details such as ID1, ID2, time, and date are stored.
5. Alongside that, a new table is created name “ABC_DEF” (ID1_ID2), and the data written by sender is stored in it.
6. Then the site creates a link to share which contains only ID2. For example, https://www.example.com/Data/?share?ID2=DEF
7. After sending this to the other person, when they try to open it, the site identifies the ?share and text after ?ID2 and searches for that row in the ‘Details’ table in mySql. Then it identifies the ID1 and ID2 and goes to retrieve the data in table ID1_ID2 to display to the user as output.

But the problem is the at all times the data is being stored in ‘Details’ and a table is being created by ID1_ID2. But at random times the data written is not being stored in the created table.
I don’t know if this is because of cache issue or what. And it’s very confusing since it works sometimes and it doesn’t. And it’s completely random on when it works and when it doesn’t.

The link is being created, the details in the ‘Details’ table are always being inserted correctly, and the table is being created every single time. But the data to be stored in the table is uncertain.

Is there any way to resolve and fix this?
I’ve used the languages HTML, CSS, jQuery, PHP, and mySql commands in PHP.

I would like to only show e.g. Stripe if coupon code 123 is used. So, I have come up with the code which is working, but I would also like to show a message at the top of the checkout, where the woo notices show. My message isn’t showing correctly.

// restrict coupon codes payment method
add_filter('woocommerce_available_payment_gateways', 'unset_gateway_by_applied_coupons');

function unset_gateway_by_applied_coupons($available_gateways) {
    // prevents coupon error in admin
    if( is_admin() ) 
        return $available_gateways;
    
    global $woocommerce;
    $unset = false; // the norm
    
    // names of coupons
    $coupon_codes = array('test123', 'check123');
            
    foreach($coupon_codes as $coupon_code) {
        
        // if code is used in cart
        if(in_array($coupon_code, WC()->cart->get_applied_coupons() )){
            //echo 'found =' .$coupon_code;
            unset($available_gateways['bacs']);
            unset($available_gateways['invoice']);
            // $message = sprintf( __('<br><p class="coupon-code">The coupon code  "%s" can only use the Credit Card payment method.</p>'), $coupon_code);  // <<<<< not working
        }
            
    }
    return $available_gateways;
}

“I created a form in React JSX, which has some input fields like name, email, age, etc. All the data from these fields is being saved in a PHP database, but the CV file is not uploading to the specified path. The path should be like ‘uploads/filename’, but it’s showing ‘C:/fake/filename’. There are no errors in the PHP code.”

I would try that my react jsx form all input fields data should be svae in php database

I’m working on a Laravel 10 project using Livewire 3, where I’m building a booking management system. In this system, users can filter bookings by various statuses using a multiple select dropdown or a series of checkboxes. However, I encountered the following error while trying to bind the checkboxes to an array in my Livewire component:

Context:

Objective:

The goal is to allow users to filter bookings by their statuses, such as “Open,” “Closed,” “In Progress,” etc. Users should be able to select multiple statuses to filter the results. This is implemented using checkboxes within a dropdown-like structure that is toggled by a button.

Problem:

The error occurs because Livewire is attempting to bind a checkbox to a specific index of the selectedBookingStatuses array (e.g., selectedBookingStatuses.0), but this index does not exist or is not initialized correctly.

The error I’m seeing is

[404] /index.php – No such file or directory

I’ve checked the file path but it’s okay. I don’t know what the problem could be.

Can anyone advise what I should do? What else should I check? I really appreciate your help and suggestions.

I need it to

1. http://site:8080/acc/cl.php opened in the browser as http://site:8080/cl.html
2. http://site:8080/acc/cl-main.php?cid=1 opened in the browser as http://site:8080/cl-main.html

So far, the only rule that works for me is for files in the root of the site, where I remove php and replace it with html

RewriteEngine on
RewriteBase /

RewriteCond %{THE_REQUEST} (.*).html
RewriteRule ^(.*).html $1.php [L]

but this rule no works

RewriteCond %{THE_REQUEST} acc/(.*).html
RewriteRule ^acc/(.+).html$ acc/$1.php [L]

I have some nextcloud code in php how to create a table. I want to convert it to mysql. Sounds like an easy task, but the docu and documentation is not clear to me.

This line:

$table->setPrimaryKey(['objecttype', 'objectid', 'systemtagid'], 'som_pk');

seems to use an array and a new column as index. I do not know where som_pk comes from and how to write it in mysql orders. Same goes for index.
Can someone give ma a hint?

Source of Code

if (!$schema->hasTable('systemtag_object_mapping')) {
    $table = $schema->createTable('systemtag_object_mapping');
    $table->addColumn('objectid', 'string', [
        'notnull' => true,
        'length' => 64,
        'default' => '',
    ]);
    $table->addColumn('objecttype', 'string', [
        'notnull' => true,
        'length' => 64,
        'default' => '',
    ]);
    $table->addColumn('systemtagid', 'integer', [

    $table->addIndex(['systemtagid', 'objecttype'], 'systag_by_tagid');

This is the mysql code I created from it. I am unsure how to create the index and can not find anything about it in php tutorials. Can someone jump in and tell me how to create the index properly?

Laravel Exception Handler:

public function render($request, Throwable $exception)
{
    if ($this->isHttpException($exception)) {
        if ($exception->getStatusCode() == 404) {
            return response()->view('frontend.test', [], 404); // If I change the status code to 200, the view can be rendered successfully.
        }
    }


    return parent::render($request, $exception);
}

What I’ve Tried:

• Ensured error_page 404 /index.php; and fastcgi_intercept_errors on; is set in the Nginx configuration.
• Cleared Laravel cache using php artisan config:clear, cache:clear, and view:clear.
• Verified that the frontend.test view exists and is error-free.
• Restarted Server.

Despite these efforts, the custom 404 page does not appear. Any insights or suggestions would be greatly appreciated!

I have code which needs to state the difference of 2 dates from a table and display the range from start date to end date (in days and weeks) on the same table as well. How can I execute it? I have this code but it doesnt seem to do anything with the dates.The column names of the dates are ‘date_started’ and ‘date_completed’. ex. 2024-07-01 to 2024-07-26

$datetime1 = date_create($_GET['date_started']);
$datetime2 = date_create($_GET['date_completed']);
$interval = date_diff($datetime1, $datetime2);

Then this is the echo that I put in the table:

<td>{$interval->format('%R%a days')}</td>

and the output is = +0 days

but I want the output to be = 3 weeks and 5 days

I’m not able to hook into WooCommerce ‘all products’ block to display a custom price range for b2b customer. I tried to look for a specific hook in the WooCommerce documentations but couldn’t figure out the correct one for it or if one exists.

This problem occurs only on a “page” which has this block. It’s working well elsewhere, such as the single product page and related products etc. I’m using Gutenberg for building the site/store.
