Question
cfinput type="checkbox" default value not posting
Hello,
Any help I can get with this issue would be appreciated, as I am new to ColdFusion and have been banging my head against the wall with this for hours.
Here is the code for my form page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<cfparam name="form.cd" default="1">
<html xmlns=" http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>
<body>
<cfform method="post" action="test2.cfm">
<cfinput type="checkbox" name="form.cd" value="2">Test my checkbox
<input type="submit" name="Submit" value="Submit" />
</cfform>
<cfoutput>#form.cd#</cfoutput>
</body>
</html>
And here is the code for my action page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns=" http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>
<body>
<cfif isdefined("form.cd")>yes</cfif>
</body>
</html>
In this configuration, whether the box is checked or not, my response page does not display anything.
I have also tried a variety of other solutions on the action page such as:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<cfparam name="form.cd" default="1">
<html xmlns=" http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>
<body>
<cfoutput>#form.cd#</cfoutput>
</body>
</html>
In this scenario, my page always displays the default value of 1.
I have also tried the previous scenario without the cfparam tag in the action page, since I set the default value of the form.cd tag in the form page. In that scenario, when the box is check, I get the result of 2 on the action page. If the box is not checked, I get the Element CD is undefined in FORM.
I know that an unchecked box does not get passed to the action page, but I thought that setting the default value would mean that the default value gets passed. Additionally, when I set the default value on the action page, I thought that the default value would only be assigned if the variable didn't already have a value, and I know that the checked box value of 2 is getting assigned, because it comes through when the box is checked and there is no cfparam tag on the action page.
Please, please, please help me understand this!!!
Many thanks!
