Answer 1

你可以让它工作如下<?php&nbsp;$db_value = 'male'; // this is the value from db?><input type="radio" name="gender" value="male" <?php if($db_value == 'male'):?>checked<?php endif;?>> Male<input type="radio" name="gender" value="female" <?php if($db_value == 'female'):?>checked<?php endif;?>> Female

Answer 2

您可以radiobutton使用if-else statement如下所示检查应选择$row['gender']哪个单选按钮值所在的列：&nbsp; &nbsp; <?php&nbsp; if($row['gender']== 'male') { ?>&nbsp; &nbsp; <input type="radio" name="gender" value="male" checked> Male&nbsp; &nbsp;<?php&nbsp; }else { ?>&nbsp; &nbsp; &nbsp;<input type="radio" name="gender" value="female" checked> Female&nbsp; &nbsp;<?php } ?>&nbsp;
