title: Confirmation message on user input in php
body: <p>I have a doubt in the following code. I have a single function for both Insert and Update. Based on the row count each function will be executed. I want to provide a Confirmation box before performing the operation. On cancel message it should not perform the function. How can I do this?<br>
  Following is the code:</p>
  
  <pre><code>if (isset($_POST['Save']))
  
  {
  
  $query = "SELECT * FROM `table_name` WHERE `submission_id` = '$submission_id'";
  
  $sqlsearch = mysql_query($query);
  
  $resultcount = mysql_num_rows($sqlsearch);
  
  
  if ($resultcount &gt; 0) 
  {
  mysql_query("UPDATE `table_name` SET 
      `name` = '$name',
      `email` = '$email',
      `phone` = '$phonenumber',
      `subject` = '$subject',
      `message` = '$message' 
      WHERE `submission_id` = '$submission_id'") or die(mysql_error());
  } 
  else 
  {
  mysql_query("INSERT INTO `table_name` (submission_id, formID, IP, 
      name, email, phone, subject, message) 
      VALUES ('$submission_id', '$formID', '$ip', 
      '$name', '$email', '$phonenumber', '$subject', '$message') ") or die(mysql_error());
          }
      }
  ?&gt;`
  </code></pre>
