Hi Amit Gupta,
You may have some misunderstanding. Every form field is validated according to its type and checked on front-end using HTML5 language & at server side using PHP language. Bypassing any field type is not possible. Following input types are available in the Application Form builder:
- Text: Accepts text & numbers as string e. g. amitgupta869
- Email: Accepts only email ids.
- Text Area: Accepts text string with line breaks.
- Checkbox: Accepts array of multiple fields.
- DropDown: Accepts one field from the dropdown.
- Radio: Accepts one field from the radio options.
- File: Accepts allowd file types.
- Number: Coming soon in next version.
Also, plugins on WordPress repository are open source. You can add, customize it according to your own need.
Regards.
