type="quotes" Escape double quotes with backslashes (\"), does not change other characters. This type does not protect against cross-site scripting. type="url"
type="moderate" Encode special characters into HTML entities for moderate cross-site scripting protection: "<", ">", single quote (') and double quote (") are encoded. Useful to allow TWiki variables in comment boxes. type="url"
type="safe" Encode special characters into HTML entities for cross-site scripting protection: "<", ">", "%", single quote (') and double quote (") are encoded. type="url"
type="entity" Encode special characters into HTML entities, like a double quote into &#034;. Does not encode newline (\n) or linefeed (\r). Useful to encode text properly in HTML input fields. type="url"
type="html" As type="entity" except it also encodes \n and \r type="url"
 
  • Example: %ENCODE{"spaced name"}% expands to spaced%20name
  • ALERT! Notes:
    • Values of HTML input fields must be entity encoded.
      Example: <input type="text" name="address" value="%ENCODE{ "any text" type="entity" }%" />
    • Double quotes in strings must be escaped when passed into other TWiki variables.
      Example: %SEARCH{ "%ENCODE{ "string with "quotes"" type="quotes" }%" noheader="on" }%

    • Use type="entity" or type="safe" to protect user input from URL parameters and external sources against cross-site scripting (XSS). type="entity" is more aggressive, but some TWiki applications might not work. type="safe" provides a safe middle ground.
