URLDecode()

Decodes an URL-encoded string.

URLDecode( string=string, charset=string, strict=boolean );

Returns: String

Argument Description Default
string
string, required

URL-encoded string.
charset
string, optional

The character encoding in which the string is encoded.

utf-8
strict
boolean, optional

Default true, uses the Apache Commons UrlDecoder which has better overall support for UTF-8 etc, but throws an exception on invalid encodings.

When false, it will attempt strict mode first, then fall back to the older custom implementation which strips out invalid encodings, if strict fails.

Introduced: 6.2.3.22

Usage Notes

With Lucee 6.1, the underlying decoder was switched to use Apache Common Codec, which is stricter but more standards compliant.

Use the strict=false argument for the older behaviour, which strips out invalid encodings and doesn't throw an exception.

By default, Lucee attempts to decode all values passed in the url and form scopes, using strict mode. If an decoding error occurs, Lucee passes the raw value thru.

Examples

encoded_string = "https%3A%2F%2Fdev%2Elucee%2Eorg%2Ft%2Fwelcome%2Dto%2Dlucee%2Ddev%2F2064";
dump(URLDecode(encoded_string)); // https://dev.lucee.org/t/welcome-to-lucee-dev/2064
