Problems with array in form object

[Blackmore]

For multiple records of a similar type in a database query, I am attempting to define some checkbox form elements from the query using an array:

  <cfset temp=ArrayNew(1)>
  <cfset i=1>
  <cfloop query="myQuery">
    <cfset temp[#i#]=#myQuery.colName#>
    <cfinput type="checkbox" name="temp[#i#]" value="#temp[i]#"/>
    <cfset i=i+1>
  </cfloop>
 

This seems to work fine in setting up the checkboxes and for returning the correct values when the form is submitted, as the <cfdump> function does display the values as required. However, the variables do not appear as if they are part an array in the <cfdump> display. Instead they appear as normal structure variables such as the 'submit' variable in the form object:

temp[1] {correct value}
temp[2] {correct value}
temp[3] {correct value}
submit 'submit'
etc.

Additionally, when I attempt to reference the variables for further manipulaton, using for example the 'IsDefined' function, the variables cannot be accessed. For example the following does not work:

<cfif IsDefined("form.temp[1]")>

Am I doing this correctly? Can anyone suggest where I am going wrong and what I should be doing instead?

isDefined doesn't check the existence of array elements.

Try using cfparam instead.
