单击按钮时显示标题框

I am wondering if there is a way to show a title box containing a message when you click a button,or as a better example,you have an input,and after php script evalute the value,and it's wrong,a title box will show up , saying "Wrong" ... Any ideas? Just with php if its possible!!

EDIT: What i am looking for,is not for a simple message like:

echo '<p></p>';

Of course i know how to do that,its basic... I was just wondering if a TITLE box can show up,like this:

  <input type=text title='Wrong'>

but after the value its evaluated...

You could achieve this by setting a GET or POST value with the button:

html:

<form method="post">
<input type="hidden" name="postvalue" value="yes">
</form>

php:

<?php
if(isset($_POST['postvalue'])){
echo "<p>messageboxtoshow</p>";
}
?>

however a solution with javascript would work way better and would look way more userfriendly, and this only works on page refresh.

Try this sample one

<?php
if(isset($_POST['submit'])){
echo "<p> Your message</p>";
}
?>
<form action=<?php $_SERVER['PHP_SELF']?> method="post" >
<input type="submit" name="submit" value="submit">

</form>

Do you mean validation per input field? You can use JQuery for that.

I made a fiddle to give you a visual idea: http://jsfiddle.net/4b3tzreo/

For example, if this is your form:

<div class="container">
    <div class="left">
        Username
    </div>
    <div class="right">
        <input type="text" name="username" id="username" />
    </div>
</div>
<div class="container">
    <div class="left">
        Password
    </div>
    <div class="right">
        <input type="password" name="password" id="password" />
    </div>
</div>
<div class="container">
    <div class="left">
        <button id="submit">Submit values</button>
    </div>
</div>

You can add a class to it when the input value is empty, like this:

$('#submit').click(function(){
   var username = $('#username').val();
    var password = $('#password').val()

    if(username === '') {
         $('#username').addClass('error');  
        alert('username is not filled');
    }

    if(password === '') {
        $('#password').addClass('error');
        alert('password is not filled');
});
