<forms:captcha />
Force the user to enter the text shown in a distorted image, to prove that they are a human being.
Note: Forms already have unintrusive spam detection enabled. CAPTCHA controls are intrusive, so use them as a last resort and only if you are actually receiving spam.
Attributes
autoFocus
bool
Auto Focus
If true, this control will attempt to focus itself after the page has loaded. Note that only one element may be focused on the page at a time.
Default = false
dataColumn
Sets the data column
The datacolumn links the form item to a key used when getting or saving from a component (as defined by the parent form).
disabled
bool
Disable Input
Disables the input, preventing user interaction
height
string
Height
Sets the height of the element. The default units are pixels. include the percentage symbol % to user percentage values.
id
string
(Required) Most form items need a unique id so that they can submit data to the server. No two form items may have the same id. For situations where multiple form items submit to the same field, see the
name attribute. Id's that begin with
contact_ will automatically save Contact information to the Contact database as long as the user has entered enough identifying information (ideally Name and Email). Check the
Contact Fields page for correct field names.
name
string
Sets the name of the form item. Most of the time, the id attribute will suffice. However, with form items that post multiple values into an array, each item will need to have the same name, followed by []. For example three controls with name="data[]", will all post into 'data'.
Radio buttons belonging to the same group will have to share the same name.
numChars
int
The number of characters in the captcha image
saveState
bool
Restore state on reload
Whether the value of the input persists when the page is revisited.
Default = false

validations
Validations
Sets the validations to be applied to the value of the form item as a comma separated string.
Eg: validations="mandatory"
width
string
Width
Sets the width of the element. The default units are pixels. include the percentage symbol % to user percentage values.
