i want to check the file is selected or not in controller if not selected then show error else upload on server. i create a html element like this <input type="file" name="car_gallery[]" multiple /> and my form has also this attribute enctype="multipart/form-data".
in controller i check like this
if($this->request->getFileMultiple('car_gallery')){
}
but this condition is always true even i did not select any file. what is solution for multiple file upload its work fine on single image
I am not sure about this either as I am having this problem too. But, I am logging (via print_r) the call to $this->request->getFileMultiple('my_file_name_here') and noticed when I submitted my form without having a file attached, a file object was created (hence returning TRUE - I think). The object has all the properties empty, except the error property is set to 4 and if this maps to PHP's File Upload Errors, it means no file was uploaded.
I wonder if the object is created specifically because of this error?
Here is the code from my logging when I submit the form with no file attached.
(
[0] => CodeIgniter\HTTP\Files\UploadedFile Object
(
[path:protected] =>
[originalName:protected] =>
[name:protected] =>
[originalMimeType:protected] =>
[error:protected] => 4
[hasMoved:protected] =>
[size:protected] => 0
[pathName:SplFileInfo:private] =>
[fileName:SplFileInfo:private] =>
)
)
I honestly don't know how to (or not to) check for an if($this->request->getFileMultiple('my_file_name_here')) if it is going to always be true whether a file is attached or not.
I could be totally wrong in all this. I am up for any help and suggestions.
If this is totally wrong or not in accord with the site rules, take it down by all means.
Just use getFiles().
$this->request->getFiles('my_file_name_here')
var_dump($this->request->getFileMultiple('car_gallery'));and see why it's marked true?
