AxKit::XSP::Param - A namespace wrapper for accessing HTTP
request paramaters by name, as XML elements.
Add the param: namespace to your XSP <xsp:page> tag:
<?xml-stylesheet href="." type="application/x-xsp"?>>
<xsp:page
language="Perl"
xmlns:xsp="
http://www.apache.org/1999/XSP/Core"
xmlns:sendmail="
http://axkit.org/XSP/param"
>
And add the taglib to AxKit (via httpd.conf or .htaccess):
AxAddXSPTaglib AxKit::XSP::Param
The XSP param: tag library implements a simple way to
access HTTP request parameters (query string and posted
form data) by field name.
Thus, the value submitted from this text box
<input type="text" name="username"/>
is available after POSTing as
<param:username/>
The same is true for information passed through the query
string.
The best way to describe this taglib's use is with a few
examples:
<p>
Greetings, <param:username />, welcome to our site!
</p>
<custom-element><param:param_name /></custom-element>
<input type="hidden" name="foo">
<xsp:attribute name="value"><param:foo/></xsp:attribute>
</input>
Note that if the specified parameter field does not exist
no error is thrown. So, this:
<input type="hidden" name="secret_data">
<xsp:attribute name="value"><param:bogus_name/></xsp:attribute>
</input>
Will result in following after proccessing:
<input type="hidden" name="secret_data" value="">
