To encode data in a URL, you can call CGI::escapeHTML() directly.

URL escaping is different from HTML escaping. I think the OP needs a module like URI::Escape. Observe the following code:

$ perl use CGI; use URI::Escape; my $orig = q{a9: _-;&<tag>'"}; printf "HTML escaped: %s\n", CGI->escapeHTML($orig); printf "URL escaped: %s\n", uri_escape($orig); ^D HTML escaped: a9: _-;&amp;&lt;tag&gt;'&quot; URL escaped: a9%3A%20_-%3B%26%3Ctag%3E'%22

Most mainstream browser can recover from common broken (unescaped) urls - space seem to be the most common. But rfc2396 is clear in this regard:

2.4.3. Excluded US-ASCII Characters Although they are disallowed within the URI syntax, we include here + a description of those US-ASCII characters that have been excluded an +d the reasons for their exclusion. <SNIP> The space character is excluded because significant spaces may disappear and insignificant spaces may be introduced when URI are transcribed or typeset or subjected to the treatment of word- processing programs. Whitespace is also used to delimit URI in man +y contexts. space = <US-ASCII coded character 20 hexadecimal> <SNIP> Data corresponding to excluded characters must be escaped in order +to be properly represented within a URI.

Named entities (like those generated by escapeHTML) are simply names for characters and do not represent URL escaping.

Test HTML snippet:

<a href="http://google.com/search?q=super search">unescaped space</a> <a href="http://google.com/search?q=super%20search">escaped space</a> <a href="http://google.com/search?q=super&amp;search">entity amp</a> <a href="http://google.com/search?q=super%26search">url-escaped amp</a +>

Attn. OP: Passing SQL statements this way is a security hole.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
