Magento2 – Can’t Get File in Post-Controller from Input in Phtml

file uploadphtml

I have a file-input field in my pthml and would like to use it to upload picture files.

[...]
                <div class="field file">
                    <label class="label" for="email"><span><?= $escaper->escapeHtmlAttr(__('Attach a picture')) ?></span></label>
                    <div class="control">
                        <input name="pictureUpload"
                               id="pictureUpload"
                               type="file"
                               class="input-file"
                               accept="image/*"
                               value="">
                    </div>
                </div>
[...]

My Post-Controller works with all other inputs but not with the file.
I tried getting it via $this->getRequest()->getFiles(); and checked $_FILES but it remains empty.
Is there another component involved that I'm missing?

My Controller extends \Magento\Framework\App\Action\Action and implements Magento\Framework\App\Action\HttpPostActionInterface.

Please check with below example your form all attributes is same like this.

<form id="contact-form" class="form contact" action="Your action" method="post" enctype="multipart/form-data">
    ............
    ............
</form>

This Form attribute enctype="multipart/form-data" is needed when you use file input in your phtml file.

In controller you can try below code for get input data.

$files = $this->getRequest()->getFiles();

Hope it will work for you!

There are a couple of ways to do this.

Assign directly to the Block:

$block->assign($var);

$block->assign(array('myvar'=>'value','anothervar'=>true));

Then you can access it in the phtml file like this:

$this->myvar

Use the Mage registry:

Mage::register('custom_var', $var);

and then use it like:

$var = Mage::registry('custom_var');

You can create function in block example as below:

public function getEvents(){
        //get values of current page
        $page=($this->getRequest()->getParam('p'))? $this->getRequest()->getParam('p') : 1;
        //get values of current limit
        $pageSize=($this->getRequest()->getParam('limit'))? $this->getRequest()->getParam('limit') : 5;

        $collection = $this->_eventCollectionFactory->create();
        $collection->addFieldToFilter('is_active',1);
        $collection->setPageSize($pageSize);
        $collection->setCurPage($page);
        $collection->getSelect()->order('main_table.start_time asc');
        return $collection;     
    }

Using below code you can call this function in phtml file

$block->getEvents();

EDIT: How to get post data in block. you need to add below code in block

protected $request;
public function __construct(
    \Magento\Framework\App\Request\Http $request,
    ....
) {
   $this->request = $request;
}
public function getPostData()
{
  // you can use below code in any function       
  $postData =  $this->getRequest()->getParams();
}
