4. Force users to capture live photos

‍

Editing the block

Click on the block and start editing on the panel that appears on the right side.

Label

This is what appears as the label for the field that suggests the user upload a file or capture an image.

‍

Description

This is the text that goes below the attached file to help the user.

‍

Required

Click on this option if you want the end-user to compulsorily upload a file or capture an image.

‍

Advanced Options

Use this option to show the advanced options to configure the counter block.

Maximum number of files allowed

Enable this option for your users to limit the number of uploads at a single time. The maximum files a user can upload is 10.

‍

File Types

By default, all kinds of files are allowed to upload. If you want a limited type of file, you should click on the file types that you want to allow.

Force Camera Capture

Tick this option if you want to force the end-users to capture images from their phone camera or web camera and not upload old photos from their galleries. For this option to work, please ensure that in the File Types option above, only Images (Camera Uploads) is selected.

‍

Image Text (Watermarks)

This option can be used to automatically put watermark text on all the image uploads. Useful for geolocation-tagging, timestamp-tagging of uploaded photos. Any other text like Customer Name, Site Name etc can also be put on the photos.

This field works exactly like any other field that supports formulae. Just type @ to see a list of all the fields defined in the app that can be put on the images.

‍

Examples

Put Geolocation, date of visit and site name on the photos: Ensure that these fields are defined in the app.

‍

Notes

• The Image Text field is a formula field, so it will accept only valid formulae supported by Clappia. For example, if we need to put field_one and field_two on the image, we can't write field_one field_two as this is not a valid formula. The correct value would be field_one & " " & field_two.
• This feature now works on the web as well as on Android and iOS apps (minimum Clappia app version 2.3.5).
• If the Image Text is dependent on a field whose value is not yet filled by the user, then that field will be replaced by an empty string in the Watermark. To avoid such scenarios, the image upload fields can be configured to show only when all dependent fields are filled. Conditional Sections can be used to achieve this.
• It might not be possible to use Date and time fields directly in the image text. Date and time fields need to be converted to text values before they can be used. Refer to this for the usage of TEXT formula.
