1. Check your HTML code

The first thing you should do is review your HTML code to verify if there are any syntax errors or missing attributes in your form elements. Make sure that your form tags have the correct attributes such as action, method, and enctype. Also, ensure that the input fields have the required attributes such as name, type, and value.

2. Use the correct input type

Another common reason for the "Invalid Form Control" error is using the wrong input type. For example, if you set the type of an input field to "email," you must ensure that the value entered in the field is a valid email address. If it's not, the browser will display an error message. Make sure that you are using the correct input types for the data you are collecting.

3. Use HTML validation tools

To make sure that your HTML code is valid and free from errors, you can use HTML validation tools such as the W3C HTML Validator. This tool will check your code for syntax errors and other issues that may be causing the "Invalid Form Control" error.

4. Update your browser

If you are using an older browser, it may not support some of the newer HTML5 form attributes. Updating your browser to the latest version can help you avoid the "Invalid Form Control" error.


The "Invalid Form Control" error in HTML can be frustrating, but it's usually caused by simple mistakes in your code. By following these troubleshooting tips, you should be able to fix the issue quickly and easily.

<form action="submit-form.php" method="post">
  <label for="email">Email:</label>
  <input type="email" id="email" name="email" required>
  <input type="submit" value="Submit">

By using the "required" attribute on the email input field, the browser will ensure that the input is not empty and it's a valid email address before submitting the form.
