Upload file from Flow Screen - Salesforce

-


Hello Trailblazers,

Today I am going to explain how we can upload a file using salesforce flows. Recently salesforce has introduced an input component – File Upload, with the help of which we can upload files as well through screen in flows. 

Before using File Upload component, let’s understand some properties to configure this component. To set these attributes we can enter simple text value or create resources or use flow constants.


Attribute   Description
 Accepted Formats  This attribute specifies the list of file types that would be accepted as input. This value should be text field with multiple extensions separated by comma. Example – ‘.docx,.pdf,.pptx’
 Allow Multiple Files  If this attribute is set True then multiple file upload will be enabled. Use global constants here.
 API Name  API Name for component.
 Disabled  Whether to keep component disabled or not.
 File Upload Label Information text above upload button.
 Hover Text  Tooltip on file upload component.
 Related Record ID  ID of the record to associate the files with. If no value is passed, the component is disabled.

Once file upload is successful you can store component’s values in below attributes so that those can be used further.
  • Content Document IDs – Ids of uploaded files, collection of text values.
  • Upload File Names – Names of uploaded files, collection of text values.
Let’s create a simple screen flow to understand use of file upload component. We will create a screen element which will upload a file related to Case record. We will add this flow to Case Record Page.
  • Click Setup.
  • In the quick find box type Flows.
  • Select Flows and click on New Flow.
  • Select Screen Flow and click on Create.

  • Since we will be using this flow on record page we will use record id as an input for this flow so that it can be used as parent id for the file. So for that we need to create new resource of type text variable and mark it as available for input.

  • You can select Auto Layout or Free Form layout for builder as per your convenience. I will be going ahead with Auto-Layout.
  • Click on Add Element (+ icon) and select Screen. 
  • Enter required information for Screen. Now from input section screen elements find File Upload and double click on it.

  • Enter desired values in API Name & File Upload Label attributes. Select variable which we created previously for record id in Related Record ID attribute.
  • Save the flow and activate it.
  • Now open any case record and click on Edit Page from Gear icon.
  • Add the flow on layout and select Pass record ID into this variable for recordId variable.


  • Now save and test this flow. 
Let me know if you face any issues.

Salesforce flow is becoming more powerful in terms of its ability to provide solutions without writing single line of code. File upload is another addition to it. We can use this component to create a form where we will take record information along with related documents in single screen and then create new record with these related documents.

Hello Trailblazers, We all know how powerful Salesforce flows are. We can achieve many functionalities using flows without writing single line of code. Recently, I came across situation where I wanted to create multiple records of an object by taking inputs from user. And I came with solution using flows where we can ask user whether he wants add another record and allow him to create multiple records. We are going to discuss that solution in this blog. We are going to use Assignment & Decision elements for implementing this solution. Here we will ask user whether he wants to add another record or not after entering details for one record. And basis on user’s input we will make decisions. We can use Loop element as well but in that case we should have idea of how many records needs to be created. With solution explained below user can create as many records. Implementation Details :  For this demo we will create flow which will take lead first name, last name & compan...

Hello Trailblazers, Today I am going discuss a newly added functionality to Salesforce Mobile platform which has given us ability to scan the barcodes from salesforce mobile app using Lightning Web Component implementation. With the help of this Barcode Scanner API we can now read UPC, QR and other type of barcodes from Lightning Web Component.  This API is made generally available by Salesforce after February 2022. Lightning Web Component uses your mobile camera and mobile OS capabilities to scan the barcode and then sends data back to LWC from where process was invoked. You can use any UI(Button, link etc.) to start barcode scanning. So, the general flow will be initiate barcode scanning from lightning web component then mobile camera will be opened and once valid barcode is scanned you will be returned to your lightning web component which initiated this scan with data which you can process. BarcodeScanner API This barcode scanner API has capability to scan single barcode as wel...

Hello Trailblazers, Though Salesforce provides wide variety of out of the functionalities, in house solutions – creating a zip file or unzipping it in apex is still something that is not provided by Salesforce. For one of my work I came across situation where I wanted to zip multiple files together and I couldn’t find anything through Salesforce documentations. After spending some time over internet, I came across few workarounds which can be used to create zip files in Salesforce.  Listing down three of them for three different platform solutions. Zippex Utility This is Apex based utility which can help you to zip files along with other useful operations. This utility code developed by Pedro Dal Col & Pliny Smith is available on GitHub and you can deploy it’s components directly to you org as well. As per me this utility is very much powerful as it provides unzip feature as well. You can have folder structure as well or you can club multiple individual files as well using Zi...
