我有一個PHP腳本，從MySQL數據庫的國家代碼讀取。例如：它輸出津巴布韋的「ZW」或意大利的「IT」。現在我有一個問題：如何選擇（selected =「selected」）基於mysql輸出的選項？

你是什麼意思，「我怎麼能選擇基於MySQL的輸出選項？」你是否說你想根據MySQL查詢中的某些內容設置一個默認值？我不明白你的標準是什麼。 – 2012-03-12 17:58:31

是的。對不起，但英文不是我的母語。 – Floppy88 2012-03-13 08:52:53

將這些選項放入數組中，$countries，其中鍵是代碼，值是名稱。

然後，在地方<option>列表使用此代碼遍歷它們，輸出，並檢查是否選擇：

<?php 
$selected = "US"; // Put value from database here. 

foreach ($countries as $key => $name) { 
?> 
    <option value="<?php echo $key; ?>" <?php 
    if ($key == $selected) { 
     echo 'selected="selected"'; 
    } 
    ?> > <?php echo $name; ?></option> 
<?php 
} 
?>

 $con = mysql_connect("localhost:3306", "root"); 

     if(!$con){ 
      die ('Error in connection'.mysql_error()); 
     } 

     $conbd = mysql_select_db("login"); 

     if(!$conbd){ 
      die('Error in connecting Database'.mysql_error()); 
     } 

     $query = "select * from abc"; 

     $result = mysql_query($query); 
     $row = mysql_fetch_assoc($result); 
    ?> 

<select> 
    <?php foreach ($row as $key => $value) {?>   
    <option value="">-Select-</option> 
    <option value="samsung" <?php if($value == 'samsung') {echo"selected";}>>samsung</option> 
    <option value="sony" <?php if($value == 'sony'){echo "selected";}?>>sony</option> 
    <option value="lg" <?php if($value == 'lg'){echo "selected";}?>>lg</option> 
    <?php } ?> 
</select>

我想這應該幫助你...

  **OR**

更具體到你的例子這裏是代碼

<?php $countries = array('afg'=>'Afghanistan', 
      'alb'=>'Albania', 
      'alg'=>'Algeria', 
      'as'=>'American Samoa', 
      'ang'=>'Angola' 
     ); 
$db_value = "alg"; // the option which you want to select it can be anything depending on wahat you want

？>

<select> 
     <option value="">-Select-</option> 
     <?php foreach ($countries as $key => $value) {?> 
     <option value="<?php echo $key; ?>" <?php if($key==$db_value){echo "selected";}?>><?php echo $value;?></option> 
     <?php }?> 
    </select>
