Troubleshooting HTML Form Inputs Not Being Submitted

If you've ever faced the issue where submitting an HTML form doesn't seem to send your input values to the server, you are not alone. Many developers encounter this problem. In this guide, we will clarify why your form inputs may not be working correctly and how to resolve this issue effectively.

The Problem at Hand

One user reported that when they clicked the submit button on their form, they could not see the $_GET['price'] in the URL. Instead, the URL appeared as follows:

The expected URL should include the value of the price input, rendered like this:

Despite checking the code with var_dump(), the variable returned NULL. The confusion arose from the HTML structure of the form, specifically with how input names were handled.

The Provided Code

The user shared their form code, which had the following structure:

What Went Wrong?

Upon inspecting the code, we find the main culprit: a missing equals sign in the input's name attribute. This small oversight can lead to significant issues. The correct format for the input field should include an equals sign:

Test Your Form After Making Changes

After correcting the code, re-validate your form by filling in a value for the price input and submitting it.

Check if the URL now reflects the correct parameters, e.g., http://localhost/form.php/?submit=calculate!&price=3.

Debug Further As Needed

If issues persist, consider using debugging functions like var_dump() to examine the contents of $_GET or other variables.

Conclusion

It's critical to ensure all attributes in your HTML are syntactically correct to avoid frustrating errors like forms not submitting data. By checking for proper syntax, such as including an equals sign in input names, you will make your code more reliable.

With this quick fix, you'll be on your way to developing forms that function as expected, ensuring smooth user experiences. Happy coding!
