Testing a quiz question

Recommended Posts

I am creating a quiz, with Multiple choice, true and false, and fill in the blanks questions.

The first 2 types are working fine, and I am working on tesing the fill the blank questions...

See code:

//QUESTION 9
if (empty($_POST["ix"])) {
		$ixErr = "Please select an answer.";
	} else {
		$ix = test_input($_POST["ix"]);
		// check if question only contains letters and whitespace
		if (!preg_match("/^[a-zA-Z ]*$/",$ix)) {
			$ixErr = "Only letters and white space allowed.";
		else ($ix == "charming") {
			$score = $score+10;
			echo "<p>9.) " . $ix . " is correct.</p>\n";
			}
		else
			{
				echo "<p>9.) " . $ix . " is incorrect.</p>\n";
			}
		}
	}

First, I am testing to see if it is empty, if yes, display error, otherwise use the test_input function on the entered information.

Then I want to test and verify that the entered data only contains characters and/or blank spaces, if that returns yes, then I want to test the content for the correct answer. But for some reason the code gets stuck upon testing for the correct answer, please note: I did try elseif, but same issue, please help, thank you.

Perhaps this will work:

<?php
//QUESTION 9
if (empty($_POST["ix"])) {
    $ixErr = "Please select an answer.";
} else {
    $ix = test_input($_POST["ix"]);
 
    // check if question only contains letters and whitespace
    if (!preg_match("/^[a-zA-Z ]*$/",$ix)) {
        $ixErr = "Only letters and white space allowed.";
    } elseif ($ix == "charming") {
        $score = $score+10;
        echo "<p>9.) " . $ix . " is correct.</p>\n";
    } else {
        echo "<p>9.) " . $ix . " is incorrect.</p>\n";
    }
}
?>
