cakephp，如何上传图片

Question

In my cake view, I have the following form:

<form enctype="multipart/form-data" action="<?php echo $this->base; ?>/reviews/upload/" method="post" target="_blank">
 <input type="file" id="file" name="file" />
 <input type="submit" />
</form>

In the ReviewsController, in the upload() method there is:

public function upload() {
    var_dump($this->request->data);        
}

but it's always empty! I already tried "this->request", "this->data" but it's always empty. What am I doing wrong?

Answer 1

Try doing it cake way,

echo $this->Form->create("Review", array("action" => "upload", "type" => "file"));
    echo $this->Form->input("my-file", array("type" => "file"));
echo $this->Form->end();

In your reviews controller

 public function upload() {
     debug($this->request->data);       
 }

Using debug over var_dump and print_r as advantage that debug can be turned off in production mode application wide by setting lowering the debug level to 0 in core.php
