Note: Page parameters are now improvized as page variables! All your existing page parameters have been moved to the Page Variables and Script  tab at the top-right of the page builder.  In this tab, you can continue to use these parameters as variables, create new page variables, and continue to pass values to them similar to page parameters. Additionally, you can configure custom logic in your page scripts to modify and manipulate these variables.

Using parameters

The page elements where parameters can be used are listed below:

• Panels : 
  
  • Display : The display aspect of text and button in a panel can be configured to display the required data.  Learn how
  • Action : The action aspect of text, image and button in a panel can be configured to display the required data.  Learn how
  • Image : The images in a panel can be configured to display the required data.  Learn how
• Chart : You can set a filter (criteria) or use ZML attributes to filter the data based on the parameter value.  Learn how
• Gauge : You can set a filter (criteria) or use ZML attributes to filter the data based on the parameter value.  Learn how

Things to know

• You can use page parameters to set  dynamic values  while loading a page.
• Parameters and their values are placed in the  query string  portion of the URL that follows a question mark. They are comprised of a key and a value pair, separated by an equal sign. For example,
  
  https://<domain>/<account_owner_name>/<appLinkName>/#<pageLinkName>?param1=<value>

  Here,  param1  is the page parameter and its value follows the equal sign. This URL format allows the data to be retained on browser refresh and reload. 

• Pages can be filtered using  multiple parameters . The ampersand ( & ) character is used to separate the parameter-value pairs. For example,
  
  https://<domain>/<account_owner_name>/<appLinkName>/#<pageLinkName>?param1=<value>&param2=<value>

Naming parameters

• Parameter names are  case-sensitive .
• You can name parameters using letters (English), numbers, and the underscore character (_).
• A parameter name must start with a letter. String, number (including record ID), date, and Boolean values can be passed as page parameter values.
• By default, the maximum number of characters allowed in a parameter name is 100.

Example

Imagine you've created an application called  Order Management . In this application, you have designed a parameterized page titled  Track your Order  that displays the order details upon entering the respective  tracking ID  (record ID). In addition to a page parameter named  tracking_id , this page has the following components:

• An  embedded stateless form  containing a single line field named  Enter your tracking ID  in which users enter their tracking IDs. Upon form submission, it'll load the same page but with the page parameter (tracking_id) appended to the page URL in the format :
  
  pageParam=singleLineFieldInput 
• A  HTML snippet  that is configured to display the order details in the form of a table based on the input tracking ID.

Creating the parameterized page

A  parameterized page  is the page that has application-level parameters to hold the input (in the form of parameter values) and render the required data on the same page. For example, you have designed a parameterized page titled  Track your Order  and added a parameter named  tracking_id . Here, the parameter values are record IDs, which are unique values for each record (order summary). Upon entering the record ID, the order details are displayed in the same page. You can create a page by following the steps in  this  page and specify the page name as  Track your Orders .

• Embedding a stateless form

Adding a parameter to your page

Embedding a stateless form in your page

1. Edit your app.
2. Navigate to the  Design  tab and open the  page builder .
3. Select  Form  from the palette on the left and choose the stateless form named  Order Tracking .
4. Click and drag the form under  Embed as Form  option to embed the form into the page.
   

   

5. Click the  Configure  option in the toolbar at the top-center of the page builder. The  Form Embed Configuration  pane will slide in from the right
6. Under the  Field values  tab, click  Configure values . Specify the value as  tracking_id  (page parameter) beside the  Enter your tracking ID  field.
   

   

7. Click  Done  at the top-right to save the configuration.

Adding a HTML snippet to your page

1. Edit your app.
2. Navigate to the  Design  tab and open the  page builder .
3. In the page builder, click  Snippets  on the left, then drag and drop the  HTML Snippet  on to the required position on your page. The  HTML Snippet  editor will appear.
   

   

4. Add the required HTML (to create a table that displays the order details), CSS, and Deluge code. Below image shows a reference code to filter and display record details using record ID in the HTML snippet.
   

   

5. Click  Save  and close the editor.
6. Access the live  Track Your Order  page and enter your tracking ID. 
7. Click  Track  to display the order details. The below gif shows how the order details are displayed based on the  tracking_id  parameter:
