如何顯示關於$ id的全部細節？

Question

我有一個表格供用戶提交他們的詢問。提交表單後，數據將轉到php文件並連接到數據庫。現在，我遇到了update.php的問題。技術上update.php會在admin.php中點擊'kemaskini'按鈕時顯示用戶個人信息的完整詳細信息。

但是這裏發生了什麼，代碼就像這樣顯示它，例如，當我點擊百合時，百合的細節就會顯示出來。但是當我點擊朱莉婭時，莉莉的細節會再次顯示。它會產生只有莉莉詳細:(

admin.php的

<tr> 
     <th>NO</th> 
     <th>NAMA PEMOHON</th> 
     <th>UNIT/JABATAN/&nbsp;<br>BAHAGIAN</th> 
     <th>NO.TELEFON</th> 
     <th>E-MAIL</th> 
     <th>DATA/LAPORAN YANG DIPOHON</th> 
     <th>TUJUAN</th> 
     <th>TINDAKAN</th> 
     <th>AGIHAN</th> 
     <th>KEMASKINI</th> 
    </tr> 

<tbody> 
<?php 
include('config.php'); 

    $bil = 0; 
    //$option = ''; 
    $results = mysql_query("SELECT * FROM pemohon"); 
    //$option .='<select>'; 
    //$count=mysql_num_rows($results); 
    // 
    while ($row = mysql_fetch_array($results, MYSQL_ASSOC)) 
    { 
    $bil++; 



    echo "<form name='update $bil' action=update.php method=post>"; ?> 
    <tr> 
     <td><center><?php echo $bil; ?></center></td>

Answer 1

在admin.php的你錯過了在INPUT標記的結束 「>」。

<input type='hidden' name='id' value=<?php echo $row['id']; ?> 

應該是

<input type='hidden' name='id' value="<?php echo $row['id']; ?>"> 

因此，隱藏的輸入未關閉，不由瀏覽器發送，所以$ _POST ['id']爲空，可能這就是爲什麼您將所有時間都記錄爲空的id。

好的做法是始終使用「」作爲值。有了它們，您可以清楚地看到標籤是否關閉，您將避免使用空格值的問題。
