From 79dfac7d2b8628d114b02493aa842acd39d39ede Mon Sep 17 00:00:00 2001 From: ash Date: Wed, 10 Apr 2013 12:36:49 +0100 Subject: typo change Uses the same defaults as were hard coded in (8 chars in length, 0-9a-aA-Z). Small change in this file means less code elsewhere when generating random character strings for the captcha word. all existing code will work the same. --- system/helpers/captcha_helper.php | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'system/helpers') diff --git a/system/helpers/captcha_helper.php b/system/helpers/captcha_helper.php index fe6c340be..731b59e14 100644 --- a/system/helpers/captcha_helper.php +++ b/system/helpers/captcha_helper.php @@ -51,7 +51,7 @@ if ( ! function_exists('create_captcha')) */ function create_captcha($data = '', $img_path = '', $img_url = '', $font_path = '') { - $defaults = array('word' => '', 'img_path' => '', 'img_url' => '', 'img_width' => '150', 'img_height' => '30', 'font_path' => '', 'expiration' => 7200, 'captcha_word_length' => 8, 'character_pool_for_generted_word' => '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'); + $defaults = array('word' => '', 'img_path' => '', 'img_url' => '', 'img_width' => '150', 'img_height' => '30', 'font_path' => '', 'expiration' => 7200, 'captcha_word_length' => 8, 'character_pool_for_generated_word' => '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'); foreach ($defaults as $key => $val) { @@ -107,9 +107,9 @@ if ( ! function_exists('create_captcha')) if (empty($word)) { $word = ''; - for ($i = 0, $mt_rand_max = strlen($character_pool_for_generted_word) - 1; $i < $captcha_word_length; $i++) + for ($i = 0, $mt_rand_max = strlen($character_pool_for_generated_word) - 1; $i < $captcha_word_length; $i++) { - $word .= $character_pool_for_generted_word[mt_rand(0, $mt_rand_max)]; + $word .= $character_pool_for_generated_word[mt_rand(0, $mt_rand_max)]; } } elseif ( ! is_string($word)) -- cgit v1.2.3-24-g4f1b
