I can send a query to mysql database with following code:

$sql = mysql_query("INSERT INTO wall VALUES('', '$message', '$replyno')");

My questions is, Is there any way to send a query with just a click on some text.

Let’s example: there are a text name Reply. I want if i click this Reply text then mysql database field value (field name: Reply, type: int) will be increase by 1.

Sorry I DON’T KNOW ABOUT JAVASCRIPT/AJAX:(

FINAL UPDATER CODE TO @DEVELOPER:

<html>
<head>
<title>Untitled Document</title>
</head>
<script language="javascript">
$("#mylink").click(function() {
$.ajax({
url: "test.php"
}).done(function() { 
$(this).addClass("done");
});
});
</script>
<body>
echo "<a href='#' id='mylink'>Reply</a>";
</body>
</html>
Php page:
<?php
include("database/db.php");
$sql = mysql_query("INSERT INTO wall VALUES('','','','','','','','1');");
?>

    You should have this link or button to be clicked wired to an ajax call using jQuery

    http://api.jquery.com/jQuery.ajax/

    It should call a php page, which contains the query you’re looking to run. You can pass in arguments with the ajax call as well, so that your $message and $replyno are set properly before executing.

    <script>
$("#mylink").click(function() {
  $data = $("#myform").serialize();
  $.ajax({
    url: "postquery.php",
    data: $data
  }).done(function() { 
     $(this).addClass("done");
  });
});
</script>

    then your php page would look something like this:

    <?php
...
$message = mysql_real_escape_string($_REQUEST['message']);
$replyno = mysql_real_escape_string($_REQUEST['replyno']);
$sql = mysql_query("INSERT INTO wall VALUES('', '$message', '$replyno')");
....
?>

    Excaping your incoming strings using “mysql_real_escape_string” is always important to prevent SQL Injection attacks on your database.

    Your HTML should look something like this:

    <html>
...
<input type="textarea"></input>
<a href="#" id="mylink">Reply</a>
...
</html>

    This will cause the previously stated jquery statement to trigger when “Reply” is clicked.

    Here is with your updated code. I corrected the link ID and also removed the form serialization data since your test code does not appear to need it. I also added the reference to the jQuery library:

    <html>
<head>
<title>Untitled Document</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script language="javascript">
$("#mylink").click(function() {
  $.ajax({
    url: "test.php"
  }).done(function() { 
     $(this).addClass("done");
  });
});
</script>
</head>
<body>
<a href='#' id='mylink'>Reply</a>
</body>
</html>

    The problems you’re likely seeing are because of your query, not the front end code. Try adding some debug code like this:

    <?php
include("database/db.php");
$sql = mysql_query("INSERT INTO wall VALUES('','','','','','','','1');");
if(!$sql)
{
  echo mysql_error();
}
?>

    Or try checking your servers error logs.
