What are common reasons for the "Captcha not displayed" issue in PHP scripts?
The "Captcha not displayed" issue in PHP scripts can occur due to incorrect path or URL for the Captcha image, missing or incorrect Captcha library files, or server configuration issues. To solve this problem, ensure that the path to the Captcha image is correct, all necessary Captcha library files are included, and the server settings allow for Captcha image generation.
<?php
// Ensure that the path to the Captcha image is correct
$captcha_image_path = 'path_to_captcha_image_folder/';
// Include necessary Captcha library files
require_once('captcha_library.php');
// Check server settings for Captcha image generation
// Make sure GD library is installed and enabled in PHP configuration
// Generate Captcha image
generate_captcha_image($captcha_image_path);
?>
