how to differentiate which submit button user clicks???

[josephChiaWY]

Hi all,

 

I am a newbie in php. I have met a problem in echoing a few submit buttons using while loop. How do i differentiate which submit button is being click in order to grab the correct data. Below are a part of my codes:

 

 

Code: ( php )

while($requestMatch = mysql_fetch_array($friendRequest)){

       

      echo "<table width=425 height=130 border=0>";

      echo "<tr>";

      echo "<td width=110 class=style2>Add as Friend?? : </td>";

      echo "<td width=55 align=left valign=middle>";

      echo "<p>";

      echo "<form action='".$_SERVER['PHP_SELF'.'QUERY_STRING']."' method='post'>";

      echo "<a href='newFriendRequest.php?test="; echo $_SESSION['reqFriendEmail']; echo "'><input name=Submit type=submit value=YES style='width: 30px; height: 14px; font-family: Lucida Sans; font-size: 9px; color:#FFFFFF; background:#FF4700; font-style: normal; font-weight: normal; border:1px #FFFFFF; display: block; cursor:pointer; text-align: center;>";

      echo "</form></p></td>";

      echo "</tr>";

      echo "</table>";

      echo "<br>"; 

           

      $_SESSION['reqFriendName'] = $requestMatch['username']; 

      $_SESSION['reqFriendEmail'] = $requestEmail;

 

         

} 

 

Note: i am doing a friend request page. The situation is when the user receives two requests and when the user click one of the "Yes" submit button. It takes the last request out of the friends request.

<?php
   //maybe like that:
   if(isset($_POST['buttonname1'])) {
      echo 'result1';
   }elseif (isset($_POST['buttonname2'])) {
      echo 'result2';
   }
?>

 

I can't see any buttons in your code. Also please write your code like

<?php while($request/*something like that*/) {
?>some html code here <?php echo $_SERVER['PHP_SELF']; ?>
some html...
<?php } ?>

 

And $_SERVER['PHP_SELF'.'QUERY_STRING'] is not right. You have to write $_SERVER['PHP_SELF'].$_SERVER['QUERY_STRING']. If you do it yourway it calls $_SERVER[php_SELFQUERY_STRING]. That element does not exist.

Yes the above one is the simplest one to be used.But this may not work when the buttons have same label or name.

Either add a hidden input with the id for that user or change the submit name for that form instance.

Best way, IMO, would be to have two different submit buttons with different values.

 

<input type="submit" name="submit" value="Yes" />

<input type="submit" name="submit" value="Go" />

 

then

<?php
switch ($_POST['submit']) {
case "Yes" :
//Code for if "Yes" button is pressed
break;
case "Go" :
//Code for if "Go" button is pressed 
break;
default:
echo "No valid submit button pressed";
break;
}
?>
