下拉选择条目选择HTML表单元素 [英] Selected Entry in a Drop Down Select HTML Form Element

问题描述

此下拉列表显示文件夹中的所有文件，其中一个文件将被选中使用。有没有办法显示加载页面时选择哪个文件？目前它每次都显示选择一个文件。

This drop down list, displaying all the files from a folder, one of which will be selected for use. Is there a way to show which file is selected when you load the page? At the moment it says "select a file" every time.

<select name="image" type="text" class="box" id="image" value="<?=$image;?>">
<option value='empty'>Select a file</option> 
<?php

$dirname = "images/";
$images = scandir($dirname);

// This is how you sort an array, see http://php.net/sort
natsort($images);

// There's no need to use a directory handler, just loop through your $images array.
foreach ($images as $file) {
    if (substr($file, -4) == ".gif") {
        print "<option value='$file'>$file</option>\n"; }
    }
?>
</select>

推荐答案

与Zak和NickF的答案类似，您可以使用

And similarly to Zak's and NickF's answers, you can use

selected="selected"

，如果你喜欢去购买XHTML的话。

in your option tag if you like to go for XHTML.
