I have verified issue. Now Deprecated code error is fixed. Now this error message is not available . So I closed the issue.

@RHSRSK , please revert the code which you push in this bug, because this error comes as we directly initialize public variable in public function in class. We must need to first define variable in class then only we have to use that public variable in any function of that class.

For example.

1. Deprecated: Creation of dynamic property WP_Event_Manager_Alerts::$post_types is deprecated in /home/wazzonau/public_html/wp-content/plugins/wp-event-manager-alerts/wp-event-manager-alerts.php on line 88

for this error, you can go in wp-content/plugins/wp-event-manager-alerts/wp-event-manager-alerts.php file and check, this $post_types variable you used as public variable in function but you didnot define it in class any where.

ans .

class WP_Event_Manager_Alerts { public $post_types;

public function __construct() {
    $this->post_types = Initialize the here
}

}

NOTE :

The best solution is to explicitly define all properties within the class. This approach ensures compatibility with future PHP versions and aligns with best practices for code clarity and maintainability. Explicitly defining properties avoids relying on workarounds that might become deprecated or less supported in the future.

Explicitly Defining Properties (Recommended Solution) Define Properties in the Class: Ensure all properties are declared within the class definition. Initialize Properties in the Constructor: Initialize properties in the constructor or appropriate methods.

ex.

class WP_Event_Manager_Alerts { public $post_types;

public function __construct() {
    $this->post_types = array(); // Initialize the property
}

}

Why Explicit Definition is Better ?

• Future Compatibility: Ensures code remains compatible with future PHP versions.
• Code Clarity: Makes the code easier to read and understand.
• Maintainability: Simplifies maintenance and debugging.

Using #[AllowDynamicProperties] (Temporary Workaround) While using #[AllowDynamicProperties] is a valid and quick solution, it should be considered a temporary workaround rather than a permanent fix. This approach is less future-proof and doesn't address the underlying issue of dynamic property creation. ex.

[AllowDynamicProperties]

class WP_Event_Manager_Alerts { // Existing properties and methods }

Explicitly defining properties is the best and recommended solution for long-term code quality and compatibility. It aligns with best practices and prepares your code for future PHP versions. Use #[AllowDynamicProperties] only as a temporary measure if immediate fixes are needed.
