我正在为网站http://mytempsite.net/gotie/mixandmatch
构建自定义衬衫制作工具我设置的是第一步,他们将从12种不同的衬衫中选择衬衫颜色,然后继续下一步,他们将能够选择领带。我需要能够将变量传递给下一页,告诉它只能拉上带有绑带的图像,例如红色衬衫。
我这样做的想法是在图像alt或title标签处设置该属性,然后从正在显示的当前图像中获取该属性。
我需要知道的是怎么做?
我尝试使用此代码作为开始
<?php
$url=$this->helper('core/url')->getCurrentUrl();;
$html = file_get_contents($url);
$doc = new DOMDocument();
@$doc->loadHTML($html);
$divs = $doc->getElementByID('loadarea');
foreach ($divs as $div) {
echo "Found the loadarea div <br />";
}
?>
但它没有用,它也导致我的页面加载速度很慢。
以防这里是缩略图的代码
<?php
$products = Mage::getModel('catalog/product')->getCollection();
foreach($products as $prod) {
$product = Mage::getModel('catalog/product')->load($prod->getId());
$pro_title = $product->getName();
$img = $product->getImageUrl();
echo "<a href='".$img."' title='".$pro_title."' rel='enlargeimage' rev='targetdiv:loadarea,enabletitle:no,trigger:click,preload:none,fx:fade'><img src='".$img."' width='100px'/></a>";
}?>
我希望我正确地说出这个问题,不要过于本地化。如果是这样,我会改写它。

我相信$ someVar = get_field('image file')应返回图像中所有标记数据的数组。然后,您可以从数组中访问数据(即$ someVar ['alt'])。
这是一个更简单的解决方案,不需要您将图像变成对象。
$html=file_get_contents("URL OF YOUR SITE");
$doc = new DOMDocument();
@$doc -> loadHTML($html);
// Add a class to your big image to identify it (ex. selected)
$tags = getElementsByClassName($doc, 'selected');
foreach ($tags as $tag) {
echo $tag->getAttribute('alt');
}
// Not my function but its very useful. I'll track down where I got it
// and add source later.
function getElementsByClassName(DOMDocument $DOMDocument, $ClassName) {
$Elements = $DOMDocument -> getElementsByTagName("*");
$Matched = array();
foreach($Elements as $node)
{
if( ! $node -> hasAttributes())
continue;
$classAttribute = $node -> attributes -> getNamedItem('class');
if( ! $classAttribute)
continue;
$classes = explode(' ', $classAttribute -> nodeValue);
if(in_array($ClassName, $classes))
$Matched[] = $node;
}
return $Matched;
}

我最终做的是当点击缩略图图像时,隐藏的文本框获取该衬衫的product_id,然后当您转到下一页时,它会自动提取该产品的产品图像。我已经插入了我的整个表单的代码,以备将来有人需要这样做:)
快乐的编码!
