My problem is as follows, I have a form where the user uploads, so that's fine, but I'd like him to insert it with another name, but if so, it inserts blank into the database.
$files=$rand."_".$_FILES['upload']['name'];
$array=implode(",", $files);
echo "<script>alert('Array: ".$array."')</script>";
With the code above, it sends the field $array empty but if I make $files=$_FILES['upload']['name']; it sends right.
Dear friend, if I understand your intention, I recommend you use the pre-defined indexes of the $_FILES of PHP directly.
You are not returning values because you are using implode delimiting by "," but $_FILES returns an array of positions as follows:
[file] => Array
(
[name] => MyFile.jpg
[type] => image/jpeg
[tmp_name] => /tmp/php/php6hst32
[error] => UPLOAD_ERR_OK
[size] => 13
);
So you do not return a value according to your code, why you did not enter an index of the array to work with and do not have "," to delimit.
