How to display an error when the uploaded files are exceeding post_max_size php?


How to display an error when the uploaded files are exceeding post_max_size php?

print_r($_FILES);

I get an empty array when I have exceeded the post_max_size

array()

I got this from php.net but I don't understand it and don't know how to do it,

If the size of post data is greater than post_max_size, the $_POST and $_FILES superglobals are empty. This can be tracked in various ways, e.g. by passing the $_GET variable to the script processing the data, i.e. , and then checking if $_GET['processed'] is set.

This is my form,

<form action="upload.php" method="post" enctype="multipart/form-data">
  <input type="file" multiple="multiple" name="file[]" />
  <input type="submit" name="upload" value="Submit"/>
</form>

Solution

  • If $_SERVER['CONTENT_LENGTH'] is non zero and $_POST and $_FILES are empty, then the upload was too big.
