How to send text to the server and manipulate it

开发者 https://www.devze.com 2023-03-23 01:35 出处：网络

I know a bit php, ajax & javascript (and jQuery) - but since I am a bit of a begginer I need a little help to connect the dots for this easy task:

I want to let the user enter sometext (lets say: "I saw开发者_如何转开发 the sun, the sun is so nice and shiny") and I want to send this text to the server and then replace the word "sun" with "moon") - send it back to the user and write to him: "I saw the moon, the moon is so nice and shiny").

I just need help with understanding:

How do I send the text to the server using php.
How do I manipulate it and sends it back to the user.

I am sure there is a tutorial for it - I just didn't know how to look for it so I am asking here - to get a good start.

    <?php
       if (isset($_POST['text']))  //only execute if some text were sent to this script
       {
          echo str_replace('sun','moon',$_POST['text']); //manipulate the text and print it
          die(); // stop script execution
       }
    ?>
    <html>
    <head>
      <script>
        $(document).ready(function(){//when document finished to load
          $('#send').click(function(){//when user clicked on send button
            var text = $('#text').val();//get the text from input field
            $.post('',{text:text},function(data){ // send the text to the current script as a post variable called text
              alert(data); // when we received the response display it in alert window
            });
          });
        });
      </script>
    </head>
    <body>
        <input type="text" id="text" />
        <input type="button" value="send" id="send" />
    </body>
    </html>

no ajax needed

<?php
if ($_POST){
    if ($_POST['name']){
        echo str_replace('sun', 'moon', $_POST['name']);
    }
}
?>
<form method="post" action="">
<input type="text" name="text" />
<input type="submit" />
</form>

if you want ajax, do this

<?php
if ($_POST){
    if ($_POST['name']){
        echo str_replace('sun', 'moon', $_POST['name']);
    }
}else{
?>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js" type="text/javascript" charset="utf-8"></script>
<script>
$("form").submit(function(){ 
       $.post('<?php echo $_SERVER['PHP_SELF']; ?>', {name:$("#name").val()},                                                                                                                   
               function(html){
                    $("body").append(html);
               }
       );
       return false;
</script>
<body>
<form method="post" action="">
<input type="text" id="name" name="name" />
<input type="submit" />
</form>  
</body>
<?php 
}
?>

Google is your friend. I searched for "ajax for beginners jquery php". There are hundreds, thousands of resources to walk you through this very thing. Here's one tutorial that I found:

http://www.devirtuoso.com/2009/07/beginners-guide-to-using-ajax-with-jquery/

Try to google for ajax and jquery tutorials. Basically it would work something like this:

Get user text input and call a javascript function that will send that text to process.php page

//input page    
function getAjax(text){

        var $data = "sentText="+ text +";

            $.ajax({
            type: "GET",
            dataType: 'text',
            url: "process.php",
            data: $data,
            success: function(output){              
                $('#responseDiv').html(output); //output is the text echoed from the php page
                }   
        });
    }

on the process.php page you take that text from a $_GET variable

//process.php
  $sentText = $_GET['sentText'];

echo $sentText.' - some new text added';
