+ *
+ * PHP 4 also has trouble referencing the CI super object within application
+ * constructors since objects do not exist until the class is fully
+ * instantiated. Basically PHP 4 sucks...
+ *
+ * Since PHP 5 doesn't suffer from this problem so we load one of
+ * two files based on the version of PHP being run.

+/*
+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:
