提交后在表单上突出显示多个选择 [英] Highlighting multiple selections on a form after submitting

问题描述

在提交表单后，下面的这个选择框会记住并突出显示一个选项。但是，当我使它成倍数时，它在提交后不会突出显示任何选择。
有关如何实现这一点的任何想法？

This select box below does remember and highlight -one- selection after submitting the form. But when i make it multiple, it doesn't highlight any of the selectionS after submitting. Any idea about how to achieve this?

预先致谢。

Thanks in advance.

<?php
$options_amount = array("0","1","2","3","4","5","6","7","8","9","10+");
$no_way = $_GET['no_way'];
?>

<select class="postform" name="no_way[]" multiple size="5">
<option <?php if ($no_way == 'all') { ?>selected="selected"<?php }?> value="all">Any</option>
<?php
foreach ($options_amount as $option) {
?><option <?php if ($no_way == $option) { ?>selected="selected"<?php }?> value="<?php echo $option; ?>"><?php echo $option; ?></option><?php }?>
</select>

推荐答案

这适用于我：

<?php
$options_amount = array("0","1","2","3","4","5","6","7","8","9","10+");
$no_way = $_GET['no_way'];
?>
<select class="postform" name="no_way[]" multiple size="5">
<option <?php if (in_array("all",$no_way)) { ?>selected="selected"<?php }?> value="all">Any</option>
<?php
foreach ($options_amount as $option) {
?><option <?php if (in_array($option,$no_way)) { ?>selected="selected"<?php }?> value="<?php echo $option; ?>"><?php echo $option; ?></option><?php }?>
</select>
