How PHP controls the input entry box

if (Isset ($_get[' modal-username ')) {
Echo Htmlspecialchars (stripslashes ($_get[' modal-username '));
} else echo "123456";
?> ">

The value of this input tag is controlled by the PHP statement, which can display a value of 123456 or Model-username.

But I want to not only show but also get focus and allow users to modify the contents of the input box after the user taps the input box.

How to write code, please give me more advice

Your input tag does not have a property disabled=disabled, it should be possible to modify the contents of input.

You can modify the input box as described above, and there is no property set on the Input tab disabled=disabled

can display normally, fill in data, modify.
Unless Modal-text-input modal-text-input-double this style has cybernetics ReadOnly

It could have been modified.

It's supposed to be the same as the class style, you can change the class by removing it.

Thank you.........
