Why Doesn't My PHP Submit Button Trigger Echoes and Table Display?

PHP Submit Button Dilemma: Unavailable Echoes and Table

Your code intends to display echoes and a table when the "Submit" button is clicked on a PHP form. However, you've encountered an issue where these elements remain hidden. This is because you're using if(isset($_POST['submit'])) to control the display of these elements, but the submit button lacks a name attribute.

Solution: Providing a Button Name

To resolve this issue, you need to provide your submit button with a name attribute. This will bind it to the $_POST['submit'] array so that when the button is clicked, PHP can recognize it and execute the intended code block. Here's the corrected HTML:

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

Why Was the Button Name Missing?

In your original code, you defined the button without specifying a name. This is the missing element that prevents if(isset($_POST['submit'])) from functioning as expected. PHP cannot track the submit action without a button name to reference within the $_POST array.

Additional Notes

• If the name attribute is omitted, the default name for the submit button becomes an empty string. This can cause conflicts or unexpected behavior if other form elements also use empty string names.
• By providing a specific name, you explicitly bind the submit button to the $_POST['submit'] array, ensuring that its existence and click action can be accurately determined.
