Question

I want to display a columns with radio buttons based on a data from mysql table and using php , but I am not able to toggle between the radio buttons. Below is the code.
while($rows = $stmt->fetch(PDO::FETCH_ASSOC)){ ?>
<tr>
<td border="0" type="hidden" style="display:none;"><input type="hidden" name="hidden" value=<?php echo $rows['member_id']; ?></td>
<td class="center"><?php echo $rows['username']; ?></td>
<td class="center"><?php echo $rows['email']; ?></td>
<?PHP if($_SESSION['user_group'] == 63){
echo '<td class="center"><input type="radio" id='?><?php echo $rows['username']; 'name="gp" value="system admin"' ?>
<?php echo ($rows['permission']== 31 )?'checked':'' ?>'</input> </td>' <?PHP ;
echo '<td class="center"><input type="radio" id='?><?php echo $rows['username']; 'name="gp" value="admin"' ?>
<?php echo($rows['permission']== 15 )?'checked':'' ?> '</input> </td>' <?PHP ;
echo '<td class="center"><input type="radio" id='?><?php echo $rows['username'];'name="gp" value="user"'
?><?php echo ($rows['permission']== 1 )?'checked':'' ?> '</input> </td>' <?PHP ; }
elseif($_SESSION['user_group'] == 31){
echo '<td class="center"><input type="radio" id='?><?php echo $rows['username']; 'name="gp" value="admin"' ?>
<?php echo($rows['permission']== 15 )?'checked':'' ?> '</input> </td>' <?PHP ;
echo '<td class="center"><input type="radio" id='?><?php echo $rows['username'];'name="gp" value="user"'
?><?php echo ($rows['permission']== 1 )?'checked':'' ?> '</input> </td>' <?PHP ; }
elseif($_SESSION['user_group'] == 15){
echo '<td class="center"><input type="radio" id='?><?php echo $rows['username'];'name="gp" value="user"'
?><?php echo ($rows['permission']== 1 )?'checked':'' ?> '</input> </td>' <?PHP ; }?>
<td class="center"><button name="update" type="update">submit</button></td>
</tr>
<?php
}
looks like there is an error in the code. Any help with it. The current rendition is below.

Answer 1

was able to figure it out. Deleted echo command from the beginning of the html column lines. the code is presented below.
while($rows = $stmt->fetch(PDO::FETCH_ASSOC)){ ?>
<tr>
<td border="0" type="hidden" style="display:none;"><input type="hidden" name="hidden" value=<?php echo $rows['member_id']; ?></td>
<td class="center"><?php echo $rows['username']; ?></td>
<td class="center"><?php echo $rows['email']; ?></td>
<?PHP if($_SESSION['user_group'] == 63){ ?>
<td class="center"><input type='radio' id=<?php echo $rows['username']; ?> name="gp" value="system admin"
<?php echo ($rows['permission']== 31 )?'checked':'' ?>></input> </td>
<td class="center"><input type='radio' id=<?php echo $rows['username']; ?> name="gp" value="admin"
<?php echo ($rows['permission']== 15 )?'checked':'' ?> ></input> </td>
<td class="center"><input type='radio' id=<?php echo $rows['username']; ?> name="gp" value="user"
<?php echo ($rows['permission']== 1 )?'checked':'' ?> ></input> </td> <?PHP }
elseif($_SESSION['user_group'] == 31){ ?>
<td class="center"><input type='radio' id=<?php echo $rows['username']; ?> name="gp" value="admin"
<?php echo ($rows['permission']== 15 )?'checked':'' ?> ></input> </td>
<td class="center"><input type='radio' id=<?php echo $rows['username']; ?> name="gp" value="user"
<?php echo ($rows['permission']== 1 )?'checked':'' ?> ></input> </td> <?PHP }
elseif($_SESSION['user_group'] == 15){ ?>
<td class="center"><input type='radio' id=<?php echo $rows['username']; ?> name="gp" value="user"
<?php echo ($rows['permission']== 1 )?'checked':'' ?> ></input> </td><?PHP }?>
This worked just fine.
