SS4: add HTML to a FormField label
Everyone knows that "Terms and Conditions" checkbox in forms. "By signing up you agree to..." with a link to the terms and condiditions. Fortunately SilverStripe escapes all HTML we pass as a Title of a FormField. But it wasn't SilverStripe when ther wasn't an easy trick for passing that link to the label.
In this case you have to pass a kind of "HTMLFragment" as Title like:
CheckboxField::create(
'TermsAndConditions',
DBField::create_field(
'HTMLFragment',
'By clicking you accept our <a href="#" title="Do not click!">Terms and Conditions</a>'
)
);
Internally HTMLFragment maps to HTMLText, but the difference is, that HTMLFragment disables shortcode parsing.
SilverStripe's casting documentation says:
- HTMLFragment is a block of raw HTML, which should not be escaped. Take care to sanitise any HTML value saved into the database.
- HTMLText is a HTMLFragment, but has shortcodes enabled. This should only be used for content that is modified via a TinyMCE editor, which will insert shortcodes.
Thanks to kinglozzer for pointing out this solution on a question by brew_jay on slack, #ss4.
Theoretically this solution should also work on SilverStripe 3.
