Declaration:
<? class CaptchaInputField extends InputField ?>
Description:
This input field will render the captcha image and a text input field. Upon the form submission, it will
check if the entered text is the same as the text displayed on the captcha image, thus making the form valid or
invalid. You can specify the image size, font file name and size, as well as the length of the captcha string.
This tag will render two tags in the resulting document - one <img> tag for the captcha image, and another
<input type="text"> tag for the captcha text entry.
This tag accepts the following attributes for the image (in addition to the normal styling attributes that will apply to the
text entry field:
- imageclass - the class attribute that will be applied to the resulting <img> tag
- imagestyle - the style attribute that will be applied to the resulting <img> tag
- imagewidth - the captcha image width (defaults to 120)
- imageheight - the captcha image height (defaults to 32)
- position - the position of the image relative to the text input field (can be one of left, right,
top, bottom). defaults to right
- font - the name of the font file to use. The font file must reside either in the resources
directory of the currentry executing action's package, or in the resources folder under the freeform
package (will search in that order). This can actually contain a path relative to those directories (like fonts/myfont.ttf).
Defaults to captcha.ttf
- fontsize - the font size (in points, pt) that will be used to render the captcha text (default 14)
- length - the lengths of the captcha text (default 5)
