Check if image has been selected for upload

I have a form were a user can enter text and also upload images. Saving the values and images works fine. If the user does not select an image, I get the error message that no file has been selected (Error 4).

How can I run the upload image part only if the user selected an image?

I have tried:

if (!empty($_FILES['files']['name'])){ Upload the Image }

if (!empty($_FILES['files'])){ Upload the Image }

if (!empty($_FILES['files']['name'])) { Upload the Image }

if ($_FILES['files']['error'] == UPLOAD_ERR_OK) { Upload the Image }

This the form:

<input type="file" name="files[]" title="Title" maxlength="10" accept="gif|jpg|jpeg|png|tiff">

Use is_uploaded_file() function to check if the user has uploaded any file or not, and then process inputs accordingly, like this:

if(is_uploaded_file($_FILES['files']['tmp_name'][0])){
    // user has uploaded a file
}else{
    // user hasn't uploaded anything
}

Above solution code is based on your name attribute of input tag,

<input ... name="files[]" ... />

If it was <input ... name="files" ... /> then the if condition would be like this:

if(is_uploaded_file($_FILES['files']['tmp_name'])){
    ...
}else{
    ...
}

Sidenote: Use var_dump($_FILES); to see the complete array structure.
