<input type="text" name ="name" value = "<?php

echo $name ;
?>" >

Answer 3

basically u have to store those data in session for a moment

Answer 4

Do you get an error if you submit the form and the name input is empty? If so declare empty $name variable outside your if statement

Answer 5

make empty public variables for your inputs

$name = ””;

make if statement (click function) for your submit button

if($_POST[”button”]) {
//if inputs are not empty store the value into the correct variable

$name = $_POST[”name”];
}

Put the php variable into your input value

<input type=”text” name=”name” value=”<?php echo $name; ?>” />
