Multiple file upload in php

Question

I wish to upload several files, put them in a folder, and store the path in the database. Any useful examples of uploading numerous files.

Note: Any form of file is acceptable.

Answer 1

I am aware that this is an old article, but anyone attempting to upload numerous files might find some more explanation helpful. What you must do is as follows:

• Input name must be be defined as an array i.e. name="inputName[]".
• Input element must have multiple="multiple" or just multiple.
• In your PHP file use the syntax "$_FILES['inputName']['param'][index]".
• Make sure to check the array for empty strings; these could be file names or path entries. Prior to counting, use an array filter().

Here is an example:

HTML:

<input name="upload[]" type="file" multiple="multiple" />

PHP:

//$files = array_filter($_FILES['upload']['name']); //something like that to be used before processing files.

// Count # of uploaded files in array
$total = count($_FILES['upload']['name']);

// Loop through each file
for( $i=0 ; $i < $total ; $i++ ) {

  //Get the temp file path
  $tmpFilePath = $_FILES['upload']['tmp_name'][$i];

  //Make sure we have a file path
  if ($tmpFilePath != ""){
    //Setup our new file path
    $newFilePath = "./uploadFiles/" . $_FILES['upload']['name'][$i];

    //Upload the file into the temp dir
    if(move_uploaded_file($tmpFilePath, $newFilePath)) {

      //Handle other code here

    }
  }
}

I hope this helps you.
