Want to love it
by ecosee·2 months ago

Works great on WooCommerce which is what I wanted it for. But it blocks all contact forms from being usable by injecting the code into forms whether you turn this option on or not. The code has flaws. Not usable if you have contact forms on your site.

PHP Notice:  Function _load_textdomain_just_in_time was called incorrect
by Tushar Sharma·3 months ago
 PHP Notice:  Function _load_textdomain_just_in_time was called <strong>incorrectly</strong>. Translation loading for the <code>math-captcha</code> domain was triggered too early.

// This warning fills up log file.
// include_once(MATH_CAPTCHA_PATH . 'includes/class-core.php'); // This loads first.
// so , add_action('plugins_loaded', array($this, 'load_defaults')); // hits first

// And hook in wp-math-captcha.php, hits after.
add_action( 'plugins_loaded', array( $this, 'load_textdomain' ) );

// so moving below method to class-core.php will sort out this warning.
public function load_textdomain() {
load_plugin_textdomain( 'math-captcha', false, MATH_CAPTCHA_REL_PATH . 'languages/' );
}
// So please, move above method to class-core.php "plugins_loaded" hook and remove from wp-math-captcha.php
