Why is My Echo and Table Not Displaying After Clicking the Submit Button?

Why if(isset($_POST['submit'])) Prevented Echo Display When Submit Button Clicked

When attempting to suppress echo and table display until the form's submit button is clicked using the if(isset($_POST['submit'])) function, issues arise. The echos and table remain concealed even when the submit button is clicked.

The error stems from the submit button's missing name attribute. Without a name, the $_POST['submit'] variable becomes inaccessible, preventing the if(isset($_POST['submit'])) function from executing properly.

Solution

To resolve this issue, assign a name to the submit button:

<p><input type="submit" value="Submit" name="submit" /></p>

With this modification, the if(isset($_POST['submit'])) function will function correctly, triggering the display of echos and the table when the submit button is pressed.
