How to get file tmp_name using JInput - file-upload

Question

I'm a bit stuck with this. I have this bit of code which manages to get the filename of my file:
class AControllerA extends JControllerForm
{
function save()
{
//Upload file
jimport('joomla.filesystem.file');
$jinput = JFactory::getApplication()->input;
$store_form = $jinput->get('jform', null, 'array');
$file = $store_form['img_url'];
echo $file;
}
}
*The file field has a name of jform[img_url];
However I cannot seem to get the 'tmp_name' for the file. Anyone know what I'm missing out? I'm a bit confused as to how jinput works...jrequest worked quite easily. Thanks!
models/forms/a.xml
<form enctype="multipart/form-data">
<fieldset>
<field
name="img_url"
type="file"
label=""
description=""
size="40"
class="inputbox"
default=""
/>
</fieldset>
</form>

Answer 1

How about like this:
$files = $input->files->get('jform', null);
$filename = $files['img_url']['tmp_name'];
echo $filename;
Check out documentation for Retrieving file data using JInput

Supposing you are using JForm and the file input type, then you can access the file using this:
$files = $jinput->files->get('jform');
$file = $files['img_url']['tmp_name']
Also make sure your form has the enctype="multipart/form-data" set, otherwise it will not work.

In your model you should have sth like this
public function getForm($data = array(), $loadData = false)
{
/**
* Get the Form
*/
$form = $this->loadForm('com_mycomponent.mycomponent', 'mycomponent',
array('control' => false, 'load_data' => $loadData));
if (empty($form)) {
return false;
}
return $form;
}
Note that $loaddata and 'control' is set to false, when 'control' is false you can get file parameters as according to the name specified in your xml i.e the output form is like:
<input name="name in xml file" type="file" />
If 'control' => 'jform'
<input name="jform[name in xml file]" type="file" />
$loaddata= false means you dont need to fetch any data from the database to the form.
in your view.html.php you should have sth like this
public function display($tpl = null)
{
$this->formData = $this->get('Form');
$this->addToolbar();
parent::display($tpl);
}
Lets suppose I'll receive the requested file in "upload" method of "mycomponent" controller then it should have sth like this:
class MycomponentControllerMycomponent extends JControllerAdmin
{
public function upload()
{
//Retrieve file details from uploaded file, sent from upload form
$file = JFactory::getApplication()->input->files->get('name in xml
**$tmp_name** = $file['tmp_name'];
}
}
$tmp_name is Your required name
