    Can this be done? Call subforms based on dropdown linked to database

    candaceCRG Level 1

      I am hoping to make a dynamic form and I'm wondering if it's possible.

       

      I have a database with about 300 entries - pieces of farm property and a few bits of info about each of those properties. I want to create a form where users can choose the applicable piece of property from a dropdown list. Based on the property they select, another dropdown would populate with the crops associated with that property. Then based on the selection made in that dropdown, a specific form will be brought up.

       

      For instance, someone selects property #102 from the dropdown. In the database, property #102 is associated with wheat, barley and corn, so the next dropdown would populate with those three crops. The user selects wheat from the dropdown and the wheat form would be called. 

       

      I hope I explained that well enough.

      Is that possible? And if it is possible, how complicated is it to do? Assuming I already have the database and subforms, would this be a weeks-long process to script, or would it be fairly straightforward?

          Yes,it could be done, here is one sample which should help : Dependent Drop down boxes (sample attached)

          On the basis of selection (change event of second drop down), you can display/hide any subform.

            Thank you! That is quite helpful.

              One more question - as this form is to be distributed to outside users (with no control over their system or whether or not they have internet access), can the database be linked/contained within the document somehow?

                Yes, in a way you can put the data as part of the script. In the above form :

                 

                <script contentType="application/x-javascript" name="courtScript">// This script object controls the interaction between the court and PO Drop-down lists.

                 

                // The array contains the court and the corresponding PO.

                 

                var myCourts = new Array(new Array (7), new Array (6), new Array (8), new Array ());

                // Create a two-dimensional array.

                                                                                            // For each court, add a 'new Array(number of PO +1)'.

                 

                // Define the court and the corresponding PO.

                // The array syntax is arrayName[index][index].

                // The first index number represents the court,

                // the second index number is the actual data value.

                 

                myCourts[0][0] = " ";        // The first items in the Drop-dowm Lists should be blank.

                myCourts[0][1] = " ";

                myCourts[1][0] = "Barnstable";    // The first data value is the court name,

                myCourts[1][1] = "";  

                myCourts[1][2] = "Smith";      // the rest are PO names.
