WebApps - Front End Edit
If a logged-in visitor to your Site has submitted a WebApp Item, they can now edit it too.
Most WebApps, including those created by the Admin and those created by visitors who are not logged in will not store the ID of a creator.
However, any WebApps created Front-End by a logged in User will store their creator's ID in the creator field.
In this example we create a variable by hard-coding a specific User ID.
You can now access the following fields inside a WebApp Layout:
- {{this.creator.id}}
- {{this.creator.name}}
- {{this.creator.first_name}}
- {{this.creator.last_name}}
- {{this.creator.created_at}}
Only owners of a WebApp Item that are logged in can view an Edit Form for that Item.
You could of course combine both of these features- creating a link to the same page including the creator_id as a query parameter and then filtering by that ID using context.params to fetch the ID from the URL.
Unlike the "Add" Form, the Front End WebApp Edit Form must be linked to the specific WebApp Item it will Edit. This means you can only output the Form inside a WebApp Detail or List Layout file.
To include the Edit Form inside a WebApp Layout, add the Liquid tag: {% include 'webapp_form_edit', layout: 'default' %} Parameters:
- layout - Optional - Choose the name of your Layout file
Important
Even if you include the Liquid Tag, the Form will only display for visitors who are logged in and are registered as that WebApp's creator.
The Edit Form will work if you use the same Layout as you used for your add Form. However, you may wish to use an alternative Layout so you can add some additional features.
As you're including the Edit Form inside a WebApp Item, you have access to the WebApp fields that are inherited from the WebApp Layout.
One example might be adding a Title to the Form which dynamically references the WebApp Item: <h3>Edit {[this.name}}</h3> Another example might be displaying the creator's name: <h4>By {[this.creator.name}}</h4>
In a Form Layout, we use the form_builder variable to dynamically add the correct name Attribute to inputs. You can use this to output the pre-filled value; instead of the name property, output the value property. For this example WebApp field: <input name="{{form_builder.fields.properties.webapp_field_1_1.name}}"> ...you can use the name field and replace .name with .value to add a value attribute:
