php - 无法在单选按钮之间切换

Question

我想根据 mysql 表中的数据并使用 php 显示带有单选按钮的列，但我无法在单选按钮之间切换。下面是代码。

                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
                }

看起来代码中有错误。任何帮助。当前的翻译如下。

能够弄清楚。从 html 列行的开头删除了 echo 命令。代码如下所示。

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 }?>
				

这工作得很好。
