Multiple File Upload in PHP

Multiple File Upload with PHP

Replace input file name like files[] not like files see following form example:

<form action="" method="post" enctype="multipart/form-data">
    <input type="file" id="file" name="files[]" multiple="multiple" accept="image/*" />
    <input type="submit" value="Upload!" />
</form>

How to upload multiple files using PHP, jQuery and AJAX

Finally I have found the solution by using the following code:

$('body').on('click', '#upload', function(e){
        e.preventDefault();
        var formData = new FormData($(this).parents('form')[0]);

        $.ajax({
            url: 'upload.php',
            type: 'POST',
            xhr: function() {
                var myXhr = $.ajaxSettings.xhr();
                return myXhr;
            },
            success: function (data) {
                alert("Data Uploaded: "+data);
            },
            data: formData,
            cache: false,
            contentType: false,
            processData: false
        });
        return false;
});

Upload multiple files using PHP

To allow multiple file uplodes you need to set attribute multiple="multiple" on the file input with a name file[]. Or you can use separate inputs with a name file[] as well. Than to store values in database make a

 foreach($_FILES['filename']['name'] as $key=>$name){
     // store each file and write data to DB for each file
     //for example to get the name of file
     $name = $_FILES['filename']['name'][$key];
 }

Uploading multiple files and renaming - PHP

You need a loop:

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

     $name_array = $_FILES['files']['name'];
     $tmp_name_array = $_FILES['files']['tmp_name'];
     // Number of files
     $count_tmp_name_array = count($tmp_name_array);

     // We define the static final name for uploaded files (in the loop we will add an number to the end)
     $static_final_name = "name";

     for($i = 0; $i < $count_tmp_name_array; $i++){
          // Get extension of current file
          $extension = pathinfo($name_array[$i] , PATHINFO_EXTENSION);

          // Pay attention to $static_final_name 
          if(move_uploaded_file($tmp_name_array[$i], "uploads/".$static_final_name.$i.".".$extension)){
               echo $name_array[$i]." upload is complete<br>";
          } else {
               echo "move_uploaded_file function failed for ".$name_array[$i]."<br>";
          }

     }

}

Upload Multiple Files In PHP

PHP

foreach($_FILES['image']['name'] as $i => $name)
{
    // now $name holds the original file name
    $tmp_name = $_FILES['image']['tmp_name'][$i];
    $error = $_FILES['image']['error'][$i];
    $size = $_FILES['image']['size'][$i];
    $type = $_FILES['image']['type'][$i];

    if($error === UPLOAD_ERR_OK)
    {
        $extension = getExtension($name);
        if( ! in_array(strtolower($extension, array('jpg', 'jpeg', 'png') )
        {
            // Error, invalid extension detected
        }
        else if ($size > $maxAllowedFileSize /* needs to be defined elsewhere */)
        {
            // Error, file too large
        }
        else
        {
            // No errors
            $newFileName = 'foo'; // You'll probably want something unique for each file.
            if(move_uploaded_file($tmp_file, $newFileName))
            {
                // Uploaded file successfully moved to new location
                $thumbName = 'thumb_image_name';
                $thumb = make_thumb($newFileName, $thumbName, WIDTH, HEIGHT);
            }
        }
    }
}

HTML

<form method="post" enctype="multipart/form-data">
    <input name="image[]" type="file" class="image-upload" />
    <input name="image[]" type="file" class="image-upload" />
    <input name="image[]" type="file" class="image-upload" />
    <input name="image[]" type="file" class="image-upload" />
    <input name="image[]" type="file" class="image-upload" />

    <!-- You need to add more, including a submit button -->
</form>

Note the name of the input elements. The [] at the end cause PHP to create an array and add the items to the array.

Make directory and upload multiple file into created directory PHP

mkdir returns a boolean (true or false), not the created directory path.

You probably want to define the path in $upload_dir but not assign the result of the mkdir to it:

$upload_dir = 'C:/fileUpload/'. $rand_name .'/';

if (mkdir($upload_dir, 0777)) {
   //process images
}

Multiple Image Upload PHP form with one input

$error=array();
$extension=array("jpeg","jpg","png","gif");
foreach($_FILES["files"]["tmp_name"] as $key=>$tmp_name) {
    $file_name=$_FILES["files"]["name"][$key];
    $file_tmp=$_FILES["files"]["tmp_name"][$key];
    $ext=pathinfo($file_name,PATHINFO_EXTENSION);

    if(in_array($ext,$extension)) {
        if(!file_exists("photo_gallery/".$txtGalleryName."/".$file_name)) {
            move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$file_name);
        }
        else {
            $filename=basename($file_name,$ext);
            $newFileName=$filename.time().".".$ext;
            move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$newFileName);
        }
    }
    else {
        array_push($error,"$file_name, ");
    }
}

and you must check your HTML code

<form action="create_photo_gallery.php" method="post" enctype="multipart/form-data">
    <table width="100%">
        <tr>
            <td>Select Photo (one or multiple):</td>
            <td><input type="file" name="files[]" multiple/></td>
        </tr>
        <tr>
            <td colspan="2" align="center">Note: Supported image format: .jpeg, .jpg, .png, .gif</td>
        </tr>
        <tr>
            <td colspan="2" align="center"><input type="submit" value="Create Gallery" id="selectedButton"/></td>
        </tr>
    </table>
</form>
