- *
- * This class is a fallback for servers that are not running PHP greater than

- *
- * This class is based on two scripts:
- *
- * Marcus Campbell's PHP implementation (GNU license)
- * http://www.tecknik.net/sha-1/
- *
- * ...which is based on Paul Johnston's JavaScript version
- * (BSD license). http://pajhome.org.uk/

- * I encapsulated the functions and wrote one additional method to fix
- * a hex conversion bug. - Rick Ellis

-// ------------------------------------------------------------------------
-
-/*
-Instructions:
-
-Load the plugin using:
-
- $this->load->plugin('captcha');
-
-Once loaded you can generate a captcha like this:
-
- $vals = array(
- 'word' => 'Random word',
- 'img_path' => './captcha/',
- 'img_url' => 'http://example.com/captcha/',
- 'font_path' => './system/fonts/texb.ttf',
- 'img_width' => '150',
- 'img_height' => 30,
- 'expiration' => 7200
- );
-
- $cap = create_captcha($vals);
- echo $cap['image'];
-
-
-NOTES:
-
- The captcha function requires the GD image library.
-
- Only the img_path and img_url are required.
-
- If a "word" is not supplied, the function will generate a random
- ASCII string. You might put together your own word library that
- you can draw randomly from.
-
- If you do not specify a path to a TRUE TYPE font, the native ugly GD
- font will be used.
-
- The "captcha" folder must be writable (666, or 777)
-
- The "expiration" (in seconds) signifies how long an image will
- remain in the captcha folder before it will be deleted. The default
- is two hours.
-
-RETURNED DATA
-
-The create_captcha() function returns an associative array with this data:
-
- [array]
- (
- 'image' => IMAGE TAG
- 'time' => TIMESTAMP (in microtime)
- 'word' => CAPTCHA WORD
- )
-
-The "image" is the actual image tag:
-<img src="http://example.com/captcha/12345.jpg" width="140" height="50" />
-
-The "time" is the micro timestamp used as the image name without the file
-extension. It will be a number like this: 1139612155.3422
-
-The "word" is the word that appears in the captcha image, which if not
-supplied to the function, will be a random string.
-
-
-ADDING A DATABASE
-
-In order for the captcha function to prevent someone from posting, you will need
-to add the information returned from create_captcha() function to your database.
-Then, when the data from the form is submitted by the user you will need to verify
-that the data exists in the database and has not expired.
-
-Here is a table prototype:
-
- CREATE TABLE captcha (
- captcha_id bigint(13) unsigned NOT NULL auto_increment,
- captcha_time int(10) unsigned NOT NULL,
- ip_address varchar(16) default '0' NOT NULL,
- word varchar(20) NOT NULL,
- PRIMARY KEY `captcha_id` (`captcha_id`),
- KEY `word` (`word`)
- )
-
-
-Here is an example of usage with a DB.
-
-On the page where the captcha will be shown you'll have something like this:
-
- $this->load->plugin('captcha');
- $vals = array(
- 'img_path' => './captcha/',
- 'img_url' => 'http://example.com/captcha/'
- );
-
- $cap = create_captcha($vals);
-
- $data = array(
- 'captcha_id' => '',
- 'captcha_time' => $cap['time'],
- 'ip_address' => $this->input->ip_address(),
- 'word' => $cap['word']
- );
-
- $query = $this->db->insert_string('captcha', $data);
- $this->db->query($query);
-
- echo 'Submit the word you see below:';
- echo $cap['image'];
- echo '<input type="text" name="captcha" value="" />';
-
-
-Then, on the page that accepts the submission you'll have something like this:
-
- // First, delete old captchas
- $expiration = time()-7200; // Two hour limit
- $DB->query("DELETE FROM captcha WHERE captcha_time < ".$expiration);
-
- // Then see if a captcha exists:
- $sql = "SELECT COUNT(*) AS count FROM captcha WHERE word = ? AND ip_address = ? AND date > ?";
- $binds = array($_POST['captcha'], $this->input->ip_address(), $expiration);
- $query = $this->db->query($sql, $binds);
- $row = $query->row();
-
- if ($row->count == 0)
- {
- echo "You must submit the word that appears in the image";
- }

-/*
-Instructions:
-
-Load the plugin using:
-
- $this->load->plugin('js_calendar');
-
-Once loaded you'll add the calendar script to the <head> of your page like this:
-
-<?php echo js_calendar_script('my_form'); ?>
-
-The above function will be passed the name of your form.
-
-Then to show the actual calendar you'll do this:
-
-<?php echo js_calendar_write('entry_date', time(), true);?>
-<form name="my_form">
-<input type="text" name="entry_date" value="" onblur="update_calendar(this.name, this.value);" />
-<p><a href="javascript:void(0);" onClick="set_to_time('entry_date', '<?php echo time();?>')" >Today</a></p>
-</form>
-
-
-Note: The first parameter is the name of the field containing your date, the second parameter contains the "now" time,
-and the third tells the calendar whether to highlight the current day or not.
-
-Lastly, you'll need some CSS for your calendar:
-
