Question

我想使用php ..在选择框中显示我的数据库值。

我的代码在这里：

SQL查询

$ home = mysql_query（“SELECT * FROM LOCATION WHERE LOCATION_ID ='$ updatehomeid'”）

或死（mysql_error（））;

$homeresult = mysql_fetch_array($home);

腓

$state = $homeresult['STATE'];

HTML

<select name="state" id="countySel2" class="choose" size="1"><option value="<?php echo $state; ?>" selected="selected">Select State</option></select>

如何在此选择框中显示db值。请任何人帮忙

感谢您提前

Answer 1

要在选择菜单上显示字符串，您应该使用：

<select name="state" id="countySel2" class="choose" size="1"><option value="<?php echo $state; ?>" selected="selected"><?php echo $state; ?></option></select>

该值未显示在UI中，它是服务器获取的内容

Answer 2

您需要while循环，并且需要在选项中回显<?php echo $state; ?>

 <select name="state" id="countySel2" class="choose" size="1">    
 <option value="Select">Select State</option>    
 <?php  while ($homeresult = mysql_fetch_array($home)) { ?>
        <option value="<?php echo $homeresult['STATE']; ?>"><?php echo $homeresult['STATE']; ?></option>
 <?php } ?>
 </select>

Answer 4

PHP

<?php $home =mysql_query ("SELECT * FROM LOCATION WHERE LOCATION_ID = '$updatehomeid'" ) or die (mysql_error());if($home){while{$homeresult=mysql_fetch_array($home){$state = $homeresult['STATE'];}}?>

<select><option value="<?php echo $state;?>"><?php echo $state;?></option></select>

Answer 5

希望这会对你有所帮助。

<?php 

$homeid = $_POST['home_id'] or $_GET['home_id'];
if($homeid == '') {
    $homeid = '3' // define default location id from database to prevent undefined value for fresh user 
}

$home = mysql_query ("SELECT * FROM LOCATION WHERE LOCATION_ID = '$homeid'" ) or die (mysql_error());

if($home){while{$homeresult=mysql_fetch_array($home){$state = $homeresult['STATE'];}}

?>

<select><option value="<?php echo $state;?>"><?php echo $state;?></option></select>
