单击 php 中的编辑按钮后，单选按钮无法编辑

Question

单击编辑按钮后未选择单选按钮。我正在尝试编辑/更新数据，但值未在表单中编辑。

   <div class="form-group col">
      <label>*Gender:-</label>
      <div class="form-group col">
        <input type='radio' name='gender' value='Male'
       // check for male value 
       ```
        <?php
          if(isset($row['gender']) == 'Male') {
              echo "checked";
          }
        ?> ``` >
        <label>Male</label>
        <input type='radio' class='ml-3' name='gender' value='Female' 
        // check for female value 
        ```<?php
          if(isset($row['gender']) == 'Female') {
              echo "checked";
          }
        ?> ```>/* radio value is not edited or selected after clicking on edit button */
        <label>Female</label>
      </div>
    </div>

Answer 1

<?php $row['gender'] = 'Male'; ?> //for checking
<?php isset($row['gender']) ? $gender = $row['gender'] : $gender = '' ?> //ternary operator...if you need you can use if..else


       <div class="form-group col">
      <label>*Gender:-</label>
      <div class="form-group col">
        <input type='radio' name='gender' value='Male'
        <?php
        if($gender == 'Male'){ echo "checked"; } else { echo ""; } ?> >
        <label>Male</label>

        <input type='radio' class='ml-3' name='gender' value='Female'
        <?php
        if($gender == 'Female'){ echo "checked"; } else { echo ""; } ?> >
        <label>Female</label>
      </div>
    </div>
