Question

我正在使用这些代码

$query = "SELECT date  FROM arrival order by date" ; 
$result = mysqli_query($con,$query)or die ("Error". mysqli_error($con)) ;  
echo "<select name='per1' id='per1'>";

while ($row = mysqli_fetch_array ($result)){?>
<option value=<?php echo $row['date'];?> selected='selected'><?php echo $row['date'];?></option>
</select>
<?php
}

?>

选择（选项列表）将数据显示为

2016-07-01
2016-07-02
2016-07-03
2016-07-04
2016-07-05
2016-07-06
and so on

它不像下拉选项列表。如何使其像下拉列表一样？

我想从选项中选择一个日期。

Answer 1

您要多次关闭// your code while($row = mysql_fetch_array($result)) { ?> <input type="hidden" name="id[]" id="id" value="<?php echo $row['id'] ?>"> <div class="form-group"> <div style="float:left"> <label> Receipt No:</label> <input type="text" class="form-control" style="width: 60% !important; color:#999999;" name="receipt_no[]" value="<?php echo $row['receipt_no']; ?>"<?php if($_SESSION['user_level'] == 2){ echo ' readonly="readonly"'; } ?>> </div> <div> <label> Date: (yyyy-mm-dd)</label> <input class="form-control" style="width: 20% !important;" type="text" name="subDate[]" value="<?php echo $row['subDate']; ?>"<?php if($_SESSION['user_level'] == 2){ echo ' readonly="readonly"'; } ?>> </div> </div> <div class="form-group"> <label> Received with thanks from:</label> <input class="form-control" style="width: 40% !important" type="text" name="name[]" id="name" value="<?php echo $row['name'] ?>"> </div> <div class="form-group"> <label> Address:</label> <input class="form-control" style="width: 40% !important" type="text" name="address[]" id="address" value="<?php echo $row['address'] ?>"> </div>中的select。将while移到外面。

</select>

您还应该引用属性值。完整的例子：

}?> </select>

有点混乱清理了一下并尝试了这个

$query = "SELECT date  FROM arrival order by date" ; 
$result = mysqli_query($con,$query)or die ("Error". mysqli_error($con)) ;

$result_array = array();

while($row = mysql_fetch_assoc($result))
{
$result_array[] = $row['date'];
}
echo "<select name='per1' id='per1'>";
foreach($result_array as $name){
echo'<option value="'.$name.'">'.$name.'</option>';
}
echo'</select>';

我相信这会做你想要的。

Php select（选项列表）
