YayMail – WooCommerce Email Customizer

Global variables defined by a theme/plugin should start with the theme/plugin prefix. Found: "$_data_column_1".

Mismatched text domain. Expected 'yaymail' but got 'dhl-for-woocommerce'.

Offloading images, js, css, and other scripts to your servers or any remote service is disallowed.

PHP file should prevent direct access. Add a check like: if ( ! defined( 'ABSPATH' ) ) exit;

Processing form data without nonce verification.

Direct database call without caching detected. Consider using wp_cache_get() / wp_cache_set() or wp_cache_delete().

Detected usage of tax_query, possible slow query.

wp_redirect() found. Using wp_safe_redirect(), along with the "allowed_redirect_hosts" filter if needed, can help avoid any chances of malicious redirects within code. It is also important to remember to call exit() after a redirect so that no other unwanted code is executed.

$_POST['data']['order_id'] not unslashed before sanitization. Use wp_unslash() or similar

A function call to __() with texts containing placeholders was found, but was not accompanied by a "translators:" comment on the line above to clarify the meaning of the placeholders.

Use placeholders and $wpdb->prepare(); found $query

Detected usage of meta_query, possible slow query.

Hook names invoked by a theme/plugin should start with the theme/plugin prefix. Found: "$hook_name".

Multiple placeholders in translatable strings should be ordered. Expected "%1$s, %2$s", but got "%s, %s" in 'Your order on %s has been %s. There are more details below for your reference:'.

The plugin name includes a restricted term. Your chosen plugin name - "YayMail - WooCommerce Email Customizer" - contains the restricted term "woocommerce" which cannot be used within in your plugin name, unless your plugin name contains one of the allowed patterns: "for woocommerce", "with woocommerce", "using woocommerce", or "and woocommerce". The term must still not appear anywhere else in your name.

load_plugin_textdomain() has been discouraged since WordPress version 4.6. When your plugin is hosted on WordPress.org, you no longer need to manually include this function call for translations under your plugin slug. WordPress will automatically load the translations for you as needed.

Use of heredoc syntax (<<<) is not allowed; use standard strings or inline HTML instead

Detected usage of meta_key, possible slow query.

Detected usage of meta_value, possible slow query.

print_r() found. Debug code should not normally be used in production.

Detected usage of a possibly undefined superglobal array index: $_POST[&#039;data&#039;][&#039;order_id&#039;]. Check that the array index exists before using it.

The &quot;/vendor&quot; directory using composer exists, but &quot;composer.json&quot; file is missing.
