reCAPTCHA plugin error messages

Posted on by

By default, on two of my installs of reCAPTCHA Plugin for WordPress – v2.7, I receive no error message if the captcha is entered incorrectly… the user of the weblog is to assume that they made a mistake I guess…

That is until I wrote this script to check for error messages being passed around on the URL by the plugin:

if (window.location.search != "") {
	var searchArray = window.location.search.split("&");
	for (var i=0; i < searchArray.length; i++) {
		var searchSubArray = searchArray[i].split("=");
		if (searchSubArray[0] == "rerror" && 
		searchSubArray[1] == "incorrect-captcha-sol") {
			document.write(&quot;<p>The two words in the picture were 
			typed incorrectly.</p>");
		}				
	}
}

Just drop that snippet into your “comments.php” template. When the captcha is filled in incorrectly, the plugin adds “rerror=incorrect-captcha-sol” to the url. This checks for that string, and if found, writes an error message in red.

  1. Couldn’t you do something like this:

    if (location.search.indexOf(“&rerror=incorrect-captcha-sol”) > 0)
