parseRawForm()
Last updated September 08, 2005

Version: 1 | Requires: CF6 | Library: UtilityLib
Description:
Since Coldfusion dumps out the empty form fields, this can mess up code that depends on blank fields for placeholders. This version keeps them in the lists.
Return Values:
Returns a structure.
Example:
<HTML>
<body>
<!--- assuming fn is in parseFn.cfm --->
<cfinclude template="parseFn.cfm">
<cfoutput>
<form action="#cgi.SCRIPT_NAME#" method="post">
Text:<input type="text" name="a" value="">
<BR>blank:
<cfloop from="1" to="10" index="i">
<input type="checkbox" name="a" size="1" value="">
</cfloop>
<BR>1:
<cfloop from="1" to="10" index="i">
<input type="checkbox" name="a" size="1" value="1">
</cfloop>
<BR>
<input type="submit">
</form>
</cfoutput>
<Cfdump var="#form#">
<cfscript>
aK = structKeyArray(form);
ArraySort(aK, 'text');
for (i = 1; i LTE arrayLen(ak); i=i+1) {
writeOutput("Item: #ak[i]#: len: #ListLen(form["#ak[i]#"])#<BR>");
}
</cfscript>
<cfdump var="#parseRawForm()#" label="parseForm()">
<Cfdump var="#GetHttpRequestData()#" label="raw http">
</body>
</html>
Parameters:
No arguments.
