cakephp 博客文章中缺少图像
我是 cakePHP 的新手，我正在尝试 cakePHP 1.3 书的博客示例。 我在此博客示例中正确上传图像。数据库中的图像名称和 DOCUMENT_ROOT/.... 中的图像正确 但现在我想在我的博客中显示图像和相关帖子。
我正在使用此代码进行图像上传...
function add() {
if (!empty($this->data)) {
if(isset($this->data["Image"]["image"]["name"])){
$file = new File($this->data["Image"]["image"]["name"]);
$ext = $file->ext();
if ($ext != 'jpg' && $ext != 'jpeg' && $ext != 'gif' && $ext != 'png') {
$this->Session->setFlash('You may only upload image files.');
}else{
if(move_uploaded_file($this->data["Image"]["image"] ["tmp_name"],$_SERVER["DOCUMENT_ROOT"]."test_om/blog/app/webroot/img/upload_image/"
. $this->data["Image"]["image"]["name"]) == true){
$this->data["Post"]["image"] = $this->data["Image"]["image"]["name"];
}
$this->Post->save($this->data);
$this->Session->setFlash('Your post has been saved.');
$this->redirect(array('action' => 'index'));
}
}
}
}
并且我正在显示此代码中的图像
<?php echo $this->Html->image('/img/upload_image/1.gif'); ?>
，并且此代码显示与所有帖子相同的图像。 但我想设置特定的图像及其相关帖子......

如果您确定一切都正确（在数据库和文件中），您应该在视图中使用类似的内容。
这是假设您按照教程中描述的方式将数据从控制器传递到视图视图:)
如果是索引视图，您应该有一个包含所有帖子信息的变量帖子，并且在视图中您将处于像 foreach 一样循环（$post as $post）。假设你的视图应该有这样的内容：
建议：使用调试工具包（cakephp 插件），这样你就可以看到传递了什么变量和结构（如 pr($variable)）
希望所有这些对你有帮助，如果没有，评论这篇文章，以便我可以在需要时尝试扩展我的答案
If you are sure you are getting everything correct (in the database and the file where it should be) you should use something like this in the view.
this is assuming you are passing the data from the controller in the way described in the tutorial to a view view :)
if is an index view you should have a variable posts that have all post info, and in the view you will be in a loop like a foreach ($post as $post). Assuming this your view should have something like this:
Suggestion: use debug kit (cakephp plugin) so you can see what variables are passed down and the structure (like a pr($variable))
Hope all this helps you, if not, comment this post so i can try to extend my answer if needed
