Using ReplaceList to replace bad characters with good characters in a string
This tutorial shows how to replace bad word/characters with good word/characters in a string. Can be used to prevent users submitting bad words. It is easy to make a custom tag of this example. Remember that bad and good character list must be the same length. (Se our custom tags: SafeText is a custom tag that let the user enter HTML code in a text form. The tag will replace all HTML code with their appropriate entity-references.)
Example code:
| <cfset text_inn = "Who the fuck is Alice?"> <!--- Define list of "bad" characters ---> <CFSET bad_chars="fuck,sex"> <!--- Define list of "good" characters ---> <CFSET good_chars="f*,-"> <!--- Replace bad words with good words ---> <CFSET safe_content=ReplaceList(text_inn, bad_chars, good_chars)> <!--- Output original text string ---> <cfoutput>#text_inn#</cfoutput><br> <!--- Output replaced text string ---> <cfoutput>#safe_content#</cfoutput> |
This will give the following output:
Who the fuck is Alice?
Who the f* is Alice?
