A form is only useful if the data it collects actually reaches somewhere. That delivery is controlled by a small set of attributes on the form element: action tells the browser where to send the data, method tells it how to send it (most commonly GET or POST), and enctype tells it how the data should be encoded on the way. Together these three attributes determine the shape of the HTTP request your server receives.
In this course the distinction matters because you will build both the front end and the code that consumes the submitted data. GET appends name/value pairs to the URL as a query string, which makes it visible, bookmarkable, cacheable, and limited in length — fine for searches and filters, wrong for passwords or anything that changes state. POST places the data in the request body, which suits larger payloads, sensitive values, and file uploads. File uploads in particular require enctype set to multipart/form-data, while the default application/x-www-form-urlencoded handles ordinary text fields.
As you watch the videos below, pay attention to three things: what the URL looks like after submission, what the request actually contains, and which attribute combination the presenter uses for each scenario. Also notice how submission is triggered — a submit button, the Enter key inside a text input, or JavaScript — because later in this module you will intercept that moment to run validation.
A beginner-friendly walkthrough of HTML forms and input tags from CodeWithHarry's Sigma Web Development series. Based on its title and placement early in the course, it is likely to cover building a form element, the common input types, and the attributes that control submission such as action and method, with hands-on code examples.
It gives you a clear, example-driven foundation for the form element and its submission attributes, which is the starting point for every other subtopic here.
Austin Gil walks through what it takes to upload a file using plain HTML, describing three main steps. Expect coverage of the file input type together with the form attributes required for uploads — notably setting the method to POST and the enctype to multipart/form-data so the binary data is encoded correctly.
This is the clearest practical demonstration of the enctype subtopic, showing exactly why the default encoding fails for files and what to use instead.
This video asks how a server can tell whether an incoming HTTP request came from a standard HTML form submission or from JavaScript. It is likely to inspect the request headers and content type produced by each path, highlighting how the browser's native submission behavior differs from a scripted fetch.
It reinforces how the browser triggers submission and what encoding it applies by default, connecting the action/method/enctype attributes to the actual HTTP request your server sees.
These videos support MO2 most directly: the CodeWithHarry tutorial establishes the action and method attributes and lets you observe the difference between a query string and a request body, while the Akamai DevRel videos extend that into encoding choices, showing why multipart/form-data is required for file uploads and how browser-generated requests differ from JavaScript-generated ones. The form-building walkthrough also reinforces MO1 by modeling well-structured markup with appropriate input types, and the discussion of how submission is triggered prepares you for the validation work in MO3 and MO4, where you will hook into the submit event before data ever leaves the page.
