Question

我有一个选择框，其中包含从数据库生成的值。如何在存储在数据库中的值上选择它？

<select name="city" class="form-control">   
<?php foreach($records->result_array() as $row) { ?>
<option value="<?=$row['id_city']?>"> 
    <?=$row['city']?>, <?=$row['country']?>
    </option>
<?php } ?>
</select>

Answer 1

我想用不同的例子来解决

<?php
$con = mysql_connect("localhost","root","root");
 $db = mysql_select_db("exampleTest",$con);
 $get=mysql_query("SELECT id FROM example ORDER BY id ASC");
$option = '';
 while($row = mysql_fetch_assoc($get))
{
  $option .= '<option value = "'.$row['id'].'">'.$row['id'].'</option>';
}
?>
<html>
<body>
<form>
 <select> 
<?php echo $option; ?>
</select>
</form>
</body>
</html>
