콤보 박스가 업데이트되지 않습니다

두 개의 PHP 페이지가 있습니다 admin_bkp.php과 db_submit.php입니다.콤보 박스가 업데이트되지 않습니다

admin_bkp.php 직원에 대한 사용자 권한을 설정하자와 MySQL의 테이블에 권한을 저장 테이블이 권리라는 사용자를 제공합니다. 직원 정보는 hs_hr_employee에서 수집되어 추가 '사용 권한'열을 사용하여 권한 tog 에테르에 저장됩니다.

처음에는 데이터를 저장할 수 있었고 페이지를 새로 고침 할 때 admin_bkp.php에 이전에 선택했던대로 콤보 상자의 기본값이 표시됩니다.

그러나 이제는 기본 값을 '모두'으로 반환합니다. 이는 원하지 않는 것입니다. 이전에 선택한 값을 표시하고 싶습니다.

이 코드입니다 '저장' 버튼

을 클릭시 값을 저장admin_php.bkp : admin_bkp.php

올바른 값이 데이터베이스에 표시되는 경우 문제는 다른 쪽 끝에 데이터를 표시하는 것입니다. 내가 이해하는 바에 따르면, 현재 선택된 권한이 '선택됨'으로 설정된 HTML 선택 상자에서 권한 목록을 출력하고 싶습니다. 맞습니까?

이 그렇다면, 여기에 코드 :

echo "<td> <select name='cb_change[]' SELECTED VALUE=".$row['Permissions']."> 
<option value='All'>All</option> 
<option value='Remote Gaming'>Remote Gaming</option> 
<option value='Landbased Gaming'>Landbased Gaming</option> 
<option value='General Gaming'>General Gaming</option> 
</select></td>";

잘못입니다. <option> 값을 현재 선택한 값과 일치시킨 다음 속성을 지정해야합니다.

예 : 작동합니다

$selected = $row['Permissions']; 
$options = array(
    "Remote Gaming", 
    "Landbased Gaming", 
    "General Gaming" 
); 
foreach ($options as $option){ 
    if($option == $selected){ 
    echo "<option value='$option' selected='selected'>$option</option>"; 
    }else{ 
    echo "<option value='$option'>$option</option>"; 
    } 
}

.

최종 편집

다음 코드는 '코드'표시는 아래에 배치해야합니다 :

이 
echo "  
    <table > 
    <tr> 
    <th>Employee Number</th> 
    <th>ID</th> 
    <th>Name</th> 
    <th>Surname</th>   
    <th>Permissions</th> 
    </tr>";

코드 :

그래서 
$options = array(
     "All", 
     "Remote Gaming", 
     "Landbased Gaming", 
     "General Gaming" 
    ); 

    while($row = mysql_fetch_array($result)) 
    { 
     echo "<tr>"; 
     echo "<td>" . $row['emp_number'] . "</td>"; 
     echo "<td>" . $row['employee_id'] . "</td>"; 
     echo "<td>" . $row['emp_firstname'] . "</td>"; 
     echo "<td>" . $row['emp_lastname'] . "</td>"; 
     #echo "<td>" . $row['Permissions'] . "</td>"; 
     echo "<td> <select name='cb_change[]'>"; 
     foreach($options as $option){ 
      if($option == $row['Permissions']){ 
       echo "<option value='" . $option . "' selected='selected'>". $option ."</option>"; 
      }else{ 
       echo "<option value='" . $option . "'>". $option ."</option>"; 
      } 
     } 
     echo "</select> </td>"; 
     echo "</tr>" ; 
     echo "<input type='hidden' name='emp_id[]' value='". $row['employee_id'] ."'>"; 
    } // end while

내가 시도한 것은 이것이지만 여러 개의 콤보 박스를 보여주고 있는데, 내가 원하지 않는 것입니다. 내가 원하는 것은 기본적으로 이전에 선택된 옵션을 표시하는 콤보 박스입니다. 내가 한 일을보기 위해 주 질문에서 코드를 업데이트했습니다. – Brian
