Question

Hello Coders,
I have a dynamically created table in PHP and for each row there is a radio button. The intention is that depending upon which radio box is selected, the user can perform multiple functions like, Delete, Amend etc. I can make this all work with hard coded “Value” for the radio button like

echo "<td>" . '<input type="radio" name="radioSelect" value="2"  checked="checked" />' .  "</td>";

What I am looking for is a way to set the “2” dynamically. For example:

while($row = mysql_fetch_array($result) and $i<=100)
 { 
  echo "<tr>";
      $sno= $row['SNo'];    

      echo "<td>" . '<input type="radio" name="radioSelect" value= $sno  checked="checked" />' .  "</td>";
 }

What is the syntax for this? Is this possible at all?

Thanks for your help.

Yes, it’s called concatenation, and you’re already doing it with the . operator after "<td>", for example.

echo "<td>" . '<input type="radio" name="radioSelect" value="' . $sno . '" checked="checked" />' .  "</td>";

I’m not sure why you put it that way, though.

echo '<td><input type="radio" name="radioSelect" value="' . $sno . '" checked="checked" /></td>';

Also, note that only one radio button with the same name can be checked at a time, so you might want to rethink what you’re doing there.
