Hiddeninput and readonly attributes in mvc

In the context of MVC (Model-View-Controller) frameworks, the hiddeninput and readonly attributes are commonly used in HTML forms to control the behavior of input fields.

  1. Hidden Input: The hiddeninput attribute is used to create an input field that is hidden from the user but can still be submitted with the form data. This is useful when you need to include certain values in the form submission that should not be visible or editable by the user. In MVC frameworks, you typically use a specific helper method or syntax to generate hidden input fields. For example, in ASP.NET MVC, you can use the Html.Hidden helper method to create a hidden input field:
@Html.Hidden("FieldName", "FieldValue")
Enter fullscreen mode Exit fullscreen mode

This will generate an HTML input field with the name "FieldName" and the value "FieldValue". When the form is submitted, this hidden field will be sent along with the other form data.

  1. Readonly Input: The readonly attribute is used to make an input field non-editable by the user. It allows the value to be displayed in the input field, but the user cannot modify or interact with it. This attribute is typically used when you want to display some data to the user that should not be changed. In MVC frameworks, you can apply the readonly attribute to an input field by setting it in the HTML attributes of the input element. For example:
<input type="text" name="FieldName" value="Value" readonly>
Enter fullscreen mode Exit fullscreen mode

In the above example, the input field with the name "FieldName" will display the value "Value" but will be non-editable.

It's worth noting that the readonly attribute only prevents user interaction with the input field on the client-side. It does not provide any server-side validation or security. Therefore, you should always validate and handle the data on the server-side to ensure its integrity and security.
