如何從我的數據庫中回顯存儲在我單選按鈕中的值？

Question

我想要回顯特定數據性別的當前值並編輯性別，如果用戶想要。我怎樣才能用這個代碼做到這一點？

這裏是我的代碼：

echo "Gender: <label class=\"radio-inline\"><input type=\"radio\" name=\"gender\" value=\"Male\" > Male</label> 
        <label class=\"radio-inline\"><input type=\"radio\" name=\"gender\" value=\"Female\"> Female</label><br/>"; 

下面是我如何得到所有的信息在我的數據庫整個代碼：

 <?php 
     while(mysqli_stmt_fetch($stmt1)) { 
     echo "First Name: <input type=\"text\" style=\"border: none; border-color: transparent;\" value=\"$first_name\"><br/>"; 
     echo "Middle Name: <input type=\"text\" style=\"border: none; border-color: transparent;\" value=\"$middle_name\"><br/>"; 
     echo "Last Name: <input type=\"text\" style=\"border: none; border-color: transparent;\" value=\"$last_name\"><br/>"; 
     echo "Age: <input type=\"text\" style=\"border: none; border-color: transparent;\" value=\"$age\"><br/>"; 
     echo "Birth Date: <select name=\"month\" style=\"width:auto;\"> 
          <option value=\"$month\"></option> 
          <option value=\"January\">January</option> 
          <option value=\"February\">February</option> 
          <option value=\"March\">March</option>

          <option value=\"August\">August</option> 
          <option value=\"September\">September</option> 
          <option value=\"October\">October</option> 
          <option value=\"November\">November</option>

          <option value=\"3\">3</option> 
          <option value=\"4\">4</option>

     echo "Gender: <label class=\"radio-inline\">

Answer 1

使用，如果在單選按鈕狀態來選擇您存儲的值如

$gender = 'Female'; 
echo "Gender: <label class=\"radio-inline\"> 
       <input type=\"radio\" name=\"gender\" value=\"Male\" "; 
       if(isset($gender) && $gender == 'Male') { echo 'checked';} 
echo " > Male</label> 
       <label class=\"radio-inline\"> 
       <input type=\"radio\" name=\"gender\" value=\"Female\" "; 
       if(isset($gender) && $gender == 'Female') { echo 'checked';} 
    echo "> Female</label><br/>"; 

Answer 2

嘗試像這樣使用單引號echo和使用雙引號它很容易做到。

<?php 

    $gender = 'Male'; 

    echo 'Gender: <label class="radio-inline"> 
        <input type="radio" name="gender" value="Male"'; 
        if(isset($gender) && $gender == 'Male') { echo 'checked="checked"'; } 
    echo ' > Male</label> 
        <label class="radio-inline"> 
        <input type="radio" name="gender" value="Female" '; 
        if(isset($gender) && $gender == 'Female') { echo 'checked="checked"'; } 
     echo '> Female</label><br/>'; 

    ?> 

Answer 3

假設您存放1女，男性和0數據庫中的表，然後再從數據庫中獲取的代碼就可以實現爲：

<input type="radio" name="gender" <?php echo $row['gender'] === '1' ?'checked="checked"':'';?>/> Male 
<input type="radio" name="gender" <?php echo $row['gender'] === '0' ?'checked="checked"':'';?>/> Female 

完蛋了。如果男性存儲在數據庫中，則第一個將被檢查，否則第二個將被檢查。
