Question

I am new to cakePHP and I am tring the blog example of cakePHP 1.3 book .
I correctly upload image in this blog example.The image name in database and image in DOCUMENT_ROOT/….correctly
but now I am wanted to show image in my blog with related post.

I am using this code for image upload…

 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'));
                    }
    }
  }

 } 

and i am showing image form this code

       <?php echo $this->Html->image('/img/upload_image/1.gif'); ?>

and this show same image with all post.
but i am wanted to set specfic image with its related post….

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.

<?php echo $this->Html->image($this->data['Post']['image']); ?>

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:

<?php echo $this->Html->image($post['Post']['image']); ?>

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
