Question

我有一个性别单选按钮。该值正在存储在 db 中，我也可以获取它。但我希望检查单选按钮的接收值。帮我。    <input type="radio" name="gender" value="male" > Male    <input type="radio" name="gender" value="female" checked> Female

Answer 1

你可以让它工作如下

<?php

 $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：

    <?php  if($row['gender']== 'male') { ?>

    <input type="radio" name="gender" value="male" checked> Male

   <?php  }else { ?>

     <input type="radio" name="gender" value="female" checked> Female

   <?php } ?>
