I have a question regarding the wordpress options validation. Just want some opinions, I am not asking for examples.
I have multiple field types, would it be the best to have multiple validation functions depending on the types? Or can that be done in 1 single function?
I assume it easier to do the separate validation functions for each type.
I have created a custom plugin to list Mp3 files from a directory in a table but I am facing an issue Joomla gives me error: 0 Class "Factory" not found
I am using Joomla 5.2.3 and PHP 8.2 on a Linux server

Anyone can please guide me as I am new in PHP and Joomla.
I am using GD library to combine two or more than two images in code igniter. The combining part is working fine. But if I open any image in my system and rotate the image and then try to combine the image then it combines with the rotated way. Means, I need to combine image always with correct orientation. If, any image is not in the correct orientation then the image must be in correct orientation then combine, below is my code.
private function combine_images($tmp_files, $output_path)
{
$merged_image_width = 0;
$merged_image_height = 0;
$image_resources = [];
// Load images, fix orientation, and calculate dimensions for the merged image
foreach ($tmp_files as $tmp_file) {
$temp_resource = null;
// Load the image based on its MIME type
switch (mime_content_type($tmp_file)) {
case 'image/jpeg':
$temp_resource = imagecreatefromjpeg($tmp_file);
break;
case 'image/png':
$temp_resource = imagecreatefrompng($tmp_file);
break;
default:
throw new Exception("Unsupported image type: " . mime_content_type($tmp_file));
}
// Fix orientation, if needed
$temp_resource = $this->fix_orientation_and_normalize($tmp_file, $temp_resource);
// Get dimensions after fixing the orientation
$width = imagesx($temp_resource);
$height = imagesy($temp_resource);
$image_resources[] = $temp_resource;
$merged_image_width = max($merged_image_width, $width); // Use the widest image
$merged_image_height += $height; // Total height for vertical stacking
}
// Create the merged image
$merged_image = imagecreatetruecolor($merged_image_width, $merged_image_height);
$y_offset = 0;
// Copy each image into the merged image
foreach ($image_resources as $image_resource) {
imagecopy($merged_image, $image_resource, 0, $y_offset, 0, 0, imagesx($image_resource), imagesy($image_resource));
$y_offset += imagesy($image_resource); // Increment vertical offset
imagedestroy($image_resource); // Free memory for each resource
}
// Save the merged image
$merged_image_path = $output_path . '/merged_image_' . time() . rand(10, 30) . '.jpg';
imagejpeg($merged_image, $merged_image_path, 100); // Save with maximum quality
imagedestroy($merged_image); // Free the merged image resource
return $merged_image_path;
}
private function fix_orientation_and_normalize($file_path, $image_resource)
{
$exif = @exif_read_data($file_path);
if (!empty($exif['Orientation'])) {
switch ($exif['Orientation']) {
case 3: // Rotate 180 degrees
$image_resource = imagerotate($image_resource, 180, 0);
break;
case 6: // Rotate 90 degrees clockwise
$image_resource = imagerotate($image_resource, -90, 0);
break;
case 8: // Rotate 90 degrees counter-clockwise
$image_resource = imagerotate($image_resource, 90, 0);
break;
}
}
// Normalize by resetting EXIF orientation (if you save the image later)
if (function_exists('imagejpeg')) {
$temp_path = sys_get_temp_dir() . '/temp_' . uniqid() . '.jpg';
imagejpeg($image_resource, $temp_path, 100);
$image_resource = imagecreatefromjpeg($temp_path); // Reload normalized image
unlink($temp_path); // Clean up temporary file
}
return $image_resource;
}

I have a implemented a webbook in my laravel application which received the events from QBO.
Problem
I also enabled the Payment event in QBO, and when I applied a payment to a single invoice, QBO successfully sent a payment event to me. However, when I applied a payment to multiple invoices, QBO did not send any event for it.
Any possible solution?
Below one is the screenshot showing a single payment made for both invoices and event not trigger against it.
New to the PHP and the MVC model structure so please be gentle as I try to figure this out as I know I making some mistakes but cannot figure out where. I have been trying to search and experiment with other submitted questions and YouTube with no luck.
Trying to query my database table personal_best and return a looped list <li></li> for the columns pb_species, pb_weight_lbs and pb_weight_oz for a specific user and display them to my webpage.
I have my model class (class PBInfo extends Dbh)
controller class (class PBInfoContr extends PBInfo)
view class (class PersonalBestInfoView extends PBInfo).
In my model class I have the following:
protected function getPBRecords($userId) {
$stmt = $this->connect()->prepare('SELECT * FROM personal_best WHERE users_id = ?;');
$stmt->execute(array($userId));
while($row = $stmt->fetchAll(PDO::FETCH_ASSOC)) {
$results [] = $row;
}
return $results;
}
In my controller class I have the following:
public function displayPBRecords() {
$row = $this->getPBRecords();
$this->row = $pbRecords;
}
In my view class I have the following code:
public function fetchPBRecords($userId) {
$personalBestInfo = $this->getPBRecords($userId);
foreach ($pbRecords as $data) {
echo "<li>".$data['pb_species']."<br>".$data['pb_weight_lbs']." lbs ".$data['pb_weight_oz']." oz</li>";
}
}
In the webpage to display the looped data I have:
<?php $personalBestRecord->fetchPBRecords($_SESSION['userid'])?>
I get the following 2 error messages when I try to run the page:
- Undefined variable $pbRecords in my view class.
- foreach() argument must be of type array|object null given in my view class.
Any suggestions would be appreciated and thanks in advance.

I want to know what is wrong with my code and how to solve the problem.
i have a library in my codeigniter4 project, now i want to make my lib with lots of functions more clear.
For that i want to know if its possible to group the functions inside the class-defination by a kind of groups and make them accessable by the groupname.
What i mean. The function “my_classfunction” of the lib “mylib” i normaly use by "$this->mylib->my_classfunction()"
Now i think to make groups of functions and access them by a kind of groupname for example “function funcA is in group testA, funB is in group testB”
and use it in a kind like "$this->mylib->testA->funcA()" – is something like this possible, and if, how?
The below query only works if $_POST[‘product_cat’] and $_POST[‘sub_category’] return something. How do I make this work if either one of these are empty?
In the end I will have 6 different optional taxonomies so I can’t really have a separate query for every combination.
query_posts(array(
'post_type' => 'product',
'post_status' => 'publish',
'tax_query' => array(
'relation' => 'AND',
array(
'taxonomy' => 'product_cat',
'terms' => $_POST['product_cat'],
),
array(
'taxonomy' => 'sub_category',
// 'field' => 'slug',
'terms' => $_POST['sub_category'],
),
...
)
));

I am looking into PHP fibers. I read that to use fibers it’s a good idea to have PHP 8.4 but my servers will only support partially 8.1 and partially 8.3 for some time ahead.
Question: Are the changes to fibers in 8.4 so significant that you would advise against using them when not having access to PHP 8.4?

I have a bunch of handlers. Every of them, eventually, contains code for saving data and releasing events.
How to test CommandHandler? What should be tested? For now it is unit tests, maybe it should be integrational? Should I mock anything or not? Why? Should it be tested at all?
Code of handlers:
public function __invoke(AddCategory $command): int
{
// some code
$this->categories->save($category);
$this->events->publishAll($category->releaseEvents());
return $category->id()->value;
}
public function __invoke(RenameCategory $command): void
{
// some code
$this->categories->save($category);
$this->events->publishAll($category->releaseEvents());
}
At the moment my tests look like that:
Test addition
protected function setUp(): void
{
$this->categories = new TestCategoryRepository();
$this->events = new TestEventDispatcher();
$this->handler = new AddCategoryHandler($this->categories, $this->events);
}
public function testHandler(): void
{
// preparing code
($this->handler)($command);
$this->assertTrue($currentEventsCountMoreThanInitialEventsCount);
$this->assertTrue($currentRepositoryCountMoreThanInitialRepositoryCount);
$this->assertIsInt($categoryId);
$this->assertNotNull($category);
}
Test some changes:
protected function setUp(): void
{
$this->categories = $this->createMock(CategoryRepository::class);
$this->events = new TestEventDispatcher();
$this->handler = new RenameCategoryHandler($this->categories, $this->events);
}
public function testHandler(): void
{
// preparing code
$this->categories->expects($this->once())
->method('getById')
->with($categoryId)
->willReturn($category);
$this->categories->expects($this->once())->method('save');
($this->handler)($command);
$this->assertTrue($currentEventsCountMoreThanInitialEventsCount);
}
I am building a backend application with some basic user authentication mechanisms, so I did what most would: creating a .env file, putting APP_SECRET inside, and having the application load from it.
Now, since I also have a database dedicated to this application, it should be feasible to store that APP_SECRET inside the database (It could be a table with just one column and one row storing the value) and have the application load from it on start.
Although I’ll still have to supply DB connection credentials via the .env file, so it won’t go anywhere, at least I have one less thing to put inside now.
The question is: Is this a legitimate move? Does this paradigm have any security concerns? Is there a better alternative if I don’t like to generate APP_SECRET and put them in .env?
