Question

Dynamic input fields...

Hi all

I've got the following question:

Assume I have a file called form.cfm which contains a form where certain input fields (input type=text) are generated dynamically from a query. More specifically I loop through my query and generate these input fields. For naming of each field I use a result ID out of my query. I looks about this way:

<cfloop>

<inpt type="text" name="#part_ID#" value="">

</cfloop>

After I try processing the form mentioned above resp. passing the form values to a file called result.cfm. There I do not understand how to get the dynamically created variables and its values!

I made a <cfdump> for the form and everything was shown fine in a struct, but I do not have any clue how to represent the struct result on a web page.

This question is most probably very basic!?

Many thanks for inputs

Kind regards

When I do stuff like this, I have a static part of the form field name.

<cfoutput query="aquery">

<input name = "abc#partnumber#">

Then on the results page, when I loop through the form fields, I look for things that start with "abc".

This method is more robust when you have more than one form field associated with the same database record.

I think it is just a different method, and just as robust as the others.

A slight variation to exclude  the name and value for submit can be written like this:

<cfloop index="i" list="#form.fieldnames#">
    <cfif #i# IS NOT "submit">
        <cfoutput>#i#: #form#</cfoutput><br>
    </cfif>
</cfloop>

On the action page, result.cfm, the story is much simpler than on the form page. When a form is submitted Coldfusion stores all the submitted fields in a comma-delimited  list. The list is form.fieldnames.

That is, you can obtain the field names (and this includes the submit field), from

<cfloop list="#form.fieldnames#" index="field">
<cfoutput>
field name:#field# <br>
field value: #form[field]#<br><br>
</cfoutput>
</cfloop>
