循环浏览不起作用的图像

Question

使用此代码，ID始终为1。我希望它在每次遍历消息时都添加+1。

如ex1，ex2，ex3等，等等。

我不知道怎么了。 有人可以帮忙吗？

foreach ($message['attachment'] as $attachment)
{
    if ($attachment['is_image'])
    {
        if ($attachment['thumbnail']['has_thumb'])
            echo '<a href="', $attachment['href'], ';image" id="link_', $attachment['id'], '" onclick="', $attachment['thumbnail']['javascript'], '"><img src="', $attachment['thumbnail']['href'], '" alt="" id="thumb_', $attachment['id'], '" border="0" class="opplastetbilde"/></a><br />';

        else
            $id = 1;

        if ($id < 10) {
            echo '<span class="zoom" id="ex' . $id . '"><img src="' . $attachment['href'] . ';image" alt="" width="' . $attachment['width'] . '" height="' . $attachment['height'] . '" border="0" class="opplastetbilde"/></span><br />';
            $id++;
        }
    }

    echo '<a href="' . $attachment['href'] . '"><img src="' . $settings['images_url'] . '/icons/clip.gif" align="middle" alt="*" border="0" />&nbsp;' . $attachment['name'] . '</a> (', $attachment['size'], ($attachment['is_image'] ? ', ' . $attachment['real_width'] . 'x' . $attachment['real_height'] . ' - ' . $txt['attach_viewed'] : ' - ' . $txt['attach_downloaded']) . ' ' . $attachment['downloads'] . ' ' . $txt['attach_times'] . '.)<br />';
}

Answer 1

在foreach之前移动它，否则它总是重新初始化$id

$id = 1;
foreach ($message['attachment'] as $attachment)
    {

Answer 2

现在，您每次遍历数组时都设置$id = 1

foreach ($message['attachment'] as $attachment) {
    // ...
    $id = 1;
    // ...
}

为了适当地增加它，您需要将其放置在循环之前

$id = 1;
foreach ($message['attachment'] as $attachment) {
    // ...
}
