Hi Andrea,
Thank you, you got my flow right and the explanation is very clear, so
I should put all the actions rely on those data into the callback
function of $.post.
for e.g.
$.post('check.php',
{username: $('#username').val(),password: $
('#password').val()},
function(data){
if (data == 'true') return true;
else return false;
});
I will try to figure it. I have 2 questions on following:
1. I handle the check.php file like:
<?php
if (!isset($_POST['username'])) echo "please input a username";
... if $username already exists, echo "the name you try to register is
already taken";
so, back to the callback function,
$.post('check.php',
{username: $('#username').val(),password: $
('#password').val()},
function(data){
if (data == 'true') return true;
else return false;
});
the "data" will be something looks like: "please input a username",
"the name you try to register is already taken", as the check.php file
outputs. instead of { data == 'ture' }.
I feel to get "data" from check.php to decide return ture or false is
not workable if I design the check.php file like above.
Any good ideas?
2. I used <form TARGET="<?php echo "$PHP_SELF"; ?>" to write the
register form & data insert in same file: register.php, is there any
way to combine the functions in check.php into register.php, which
means all of the actions will be executed in 1 file? looks like
$.post('register.php'), (call itself), are there any good solutions?
