Creating a URL parameter to pass to the confirmation page (ColdFusion)

Creating a URL parameter to pass to the confirmation page (ColdFusion)

The links on the results page not only have to open the confirmation page, they must pass the ID of the record the user wants to delete. The confirmation page will use this ID to find the record in the database and display it.

You must pass the record ID to the confirmation page with a URL parameter. This section describes how to create a URL parameter to pass the record ID to the confirmation page.

To create the URL parameter:

  1. Select the Delete link on the results page.

    If Live Data view is turned on, select the link in the first row.

  2. In the Link text box in the Property inspector, add the following string at the end of the URL:
    ?recordID=#recordsetName.fieldName#
    

    The question mark tells the server that what follows is one or more URL parameters. The word recordID is the name of the URL parameter (you can make up any name you like). Note the name of the URL parameter because you'll use it in the confirmation page later.

    The expression after the equal sign is the value of the parameter. In this case, the value is generated by a ColdFusion expression that returns a record ID from the recordset. A different ID is generated for each row in the dynamic table. In the ColdFusion expression, replace recordsetName with the name of your recordset, and replace fieldName with the name of the field in your recordset that uniquely identifies each record. In most cases, the field will consist of a record ID number. In the following example, the field consists of unique location codes:

    confirmDelete.cfm?recordID=#rsLocations.CODE#
    

    When the page runs, the values of the recordset's CODE field are inserted in the corresponding rows in the dynamic table. For example, if the Canberra, Australia, rental location has the code CBR, then the following URL will be used in the Canberra row in the dynamic table:

    confirmDelete.cfm?recordID=CBR
    
  3. Save the page.

After creating a dynamic URL parameter for the delete links, the next step is to display the record on the confirmation page. See Displaying the record on the confirmation page (ColdFusion).
