如何以編輯形式在組合框上顯示數據

Question

我從插入表單上的組合框中選擇一個數據並存儲在數據庫中..那么我想在編輯表單上顯示該數據，但是如果我想更改數據，我可以再次從組合框中選擇..您能幫我嗎？ 謝謝

此代碼在我的編輯表單上：

<select class="select" name="category">
<option>Choose Category</option>

<?php
require_once './db_freelancer.php';
$get_data = mysqli_query($mysqli, "select * from project_category");
while($category = mysqli_fetch_array($get_data)){

echo "  <option value=".$category['category_id'].">".$category['category_name']."</option>";
}
?>

</select>

Answer 1

您可以嘗試以下代碼...。根據您的數據結構編輯此代碼

$member_category = $memberdata['category_id']; // Retrieve member's category from database.


<select class="select" name="category">
<option>Choose Category</option>

<?php
   require_once './db_freelancer.php';
   $get_data = mysqli_query($mysqli, "select * from project_category");
      while($category = mysqli_fetch_array($get_data)){

 echo '<option value="'.$category['category_id'].'" '.(($category['category_id']==''.$member_category.'')?'selected="selected"':"").'>'.$category['category_name'].'</option>';
  } ?>

 </select>
