Question

I have an interesting problem here…

<cfloop from="1" to="#form.countField#" index="i">
<cfif isdefined('form["semester#i#"]')>
  <cfquery name = "insertCourses" datasource="cas_evaluation">
  INSERT INTO courses (faculty, semester, course, students, hours, team_taught, first_time, ec_dl, online, course_revision )
  VALUES ( '#form.name#', '#form['semester#i#']#', '#form['course#i#']#', '#form['numstudents#i#']#', '#form['hours#i#']#', '#form['team#i#']#', '#form['firsttime#i#']#', '#form['ec_dl#i#']#', '#form['online#i#']#', '#form['revision#i#']#')
  </cfquery>
 </cfif>
</cfloop>

Basically, I have some dynamic fields that can be added in or deleted. (These are rows of fields btw…) The way I have it coded…if the user deletes a row in the middle… ( they delete row 2 and rows 1 and 3 are left…) it causes problems because the loop is looking for it but it is not there obviously. So I tried checking to see if one of the fields were defined…but it doesn’t like the syntax of the isdefined variable.. 🙁

any suggestions?

I don’t quite understand the question. So this isn’t working?

<cfif isdefined('form["semester#i#"]')>

Use

<cfif structKeyExists(form, "semester#i#")>

cfparam and isDefined don’t like the array style syntax. In your case you could also use:

<cfif isdefined('form.semester#i#')>

Personally it’s not a style I like myself but it should work ok.
