PHP Multiple File Array

Question

I have the following code which works and uploads but it will not cycle through the array to upload every file, just the first file.

<form method="post" enctype="multipart/form-data" action="http://<?php echo $pageURL;?>">   
<input class="new" multiple="multiple" name="documents[]" type="file" />
<input class="new" multiple="multiple" name="documents[]" type="file" />
<input type="submit" class="button" name="addMaterials" value="Add" />

<?php

    foreach($_FILES['documents']['tmp_name'] as $key => $tmp_name)
        {
            $file_name = $key.$_FILES['documents']['name'][$key];
            $file_size =$_FILES['documents']['size'][$key];
            $file_tmp =$_FILES['documents']['tmp_name'][$key];
            $file_type=$_FILES['documents']['type'][$key];  
            move_uploaded_file($file_tmp,"files/".time().$file_name);
        }
?>

I need it to cycle through my documents[] file array.

Example print_r() of the documents array:

Array ( 
    [name] => Array ( [0] => AcroRd32.exe ) 
    [type] => Array ( [0] => application/x-msdownload ) 
    [tmp_name] => Array ( [0] => C:\xampp\tmp\phpE8BD.tmp ) 
    [error] => Array ( [0] => 0 ) 
    [size] => Array ( [0] => 1343112 ) 
    )

Any help appreciated.

Answer 1

you can use my updated code and as per my demo it is working perfect for multiple file upload

 <?php
if(isset($_FILES['documents'])){

foreach($_FILES['documents']['tmp_name'] as $key => $tmp_name)
{
    $file_name = $key.$_FILES['documents']['name'][$key];
    $file_size =$_FILES['documents']['size'][$key];
    $file_tmp =$_FILES['documents']['tmp_name'][$key];
    $file_type=$_FILES['documents']['type'][$key];  
    move_uploaded_file($file_tmp,"galleries/".time().$file_name);
}
}else{
echo "<form enctype='multipart/form-data' action='test1.php' method='POST'>";
 echo "File:<input name='documents[]' multiple='multiple' type='file'/><input type='submit' value='Upload'/>";

 echo "</form>";
}
?>

For anyone trying to do it with a single file php function (i`m using classes, but you can change to a function):

html:

                        <input type="file" name="foto[]" />
                        <input type="file" name="foto[]" />
                        <input type="file" name="foto[]" />
                        <input type="file" name="foto[]" />
                        <input type="file" name="foto[]" />

php:

if (isset($_FILES['foto'])) {

      $arquivo = array();
    foreach ($_FILES['foto']["name"] as $file=>$key) {

                    // the empty input files create an array index too, so we need to
                    // check if the name exits. It means the file exists.
        if (!empty($_FILES['foto']["name"][$file])) {
          $arquivo ["name"] = $_FILES['foto']["name"][$file];
          $arquivo ["type"] = $_FILES['foto']["type"][$file];
          $arquivo ["tmp_name"] = $_FILES['foto']["tmp_name"][$file];
          $arquivo ["error"] = $_FILES['foto']["error"][$file];
          $arquivo ["size"] = $_FILES['foto']["size"][$file];

$foto = new foto(); // create an obj foto
    // $arquivo means file, it`s our file format as a single $_file['file']
if ($foto -> upload($arquivo)) { // if its uploaded than save
    $foto -> save();
}


    }

    } 

}

on my foto class:

public function upload($foto) {

    $upload_dir = "D:/xampp/htdocs/prova/fotos/";
    $file_dir = $upload_dir . $foto["name"];

    $move = move_uploaded_file($foto["tmp_name"], $file_dir);
    $this -> arquivo = $foto["name"]; // use this to save to db later

    // this serves to return true if the file is uploaded
    $retorno = ($move) ? 1 : 0; 
    return $retorno;

}
