mengunggah beberapa file gambar ke galeri php mysql

Di formulir Anda, tambahkan beberapa input file. Salah satu caranya adalah dengan menggunakan nama array - image[]

Image to upload: <input type="file" name="image[]" /><br />
Image to upload: <input type="file" name="image[]" /><br />
Image to upload: <input type="file" name="image[]" /><br />
....  // as many as you want. Just be aware of upload_max_filesize, memory_limit, post_max_size etc.
<br /> 

Kemudian di uploader.php , bungkus kode unggah file Anda dengan for loop

for($i=0;$i<count($_FILES["image"]["name"]);$i++){

    $fileData = pathinfo(basename($_FILES["image"]["name"][$i]));

     ...

    if (move_uploaded_file($_FILES["image"]["tmp_name"][$i], $target_path))
    {
      ...

      echo "The image {$_FILES['image']['name'][$i]} was successfully uploaded and added to the gallery<br />";

    }
    else
    {
     echo "There was an error uploading the file {$_FILES['image']['name'][$i]}, please try again!<br />";
    }
} // close your foreach

manual memiliki bagian yang bagus tentang jebakan umum saat mengunggah file, terutama banyak. http://www.php.net/manual /en/features.file-upload.common-pitfalls.php

Jika Anda ingin melakukan beberapa dari yang lain, itu dapat dilakukan dengan cara yang sama (saya menyingkat pilihan untuk mengurangi salin/tempel) -

<form enctype="multipart/form-data" action="uploader.php" method="POST">

    // 1st set
    Category: <select class="text" name="dataType[]" />
    ...
    </select><br />
    <br />        

    Caption: <input type="text" name="title[]" /><br />
    <br />

    Image to upload: <input type="file" name="image[]" /><br />
    <br /> 

    // 2nd set
    Category: <select class="text" name="dataType[]" />
    ...
    </select><br />
    <br />        

    Caption: <input type="text" name="title[]" /><br />
    <br />

    Image to upload: <input type="file" name="image[]" /><br />
    <br />  

   // and so on, as many as you want  
   ...
    <input type="submit" value="Upload">
</form>

dan php Anda, letakkan loop for di sekitar semua elemen

for($i=0;$i<count($_FILES["image"]["name"]);$i++){

    $dataType = mysql_real_escape_string($_POST["dataType"][$i]);  // get the dataType with the same key - $i
    $title = mysql_real_escape_string($_POST["title"][$i]);   // get the title with the same key - $i

    $fileData = pathinfo(basename($_FILES["image"]["name"][$i]));

     ...

    if (move_uploaded_file($_FILES["image"]["tmp_name"][$i], $target_path))
    {
      ...

      echo "The image {$_FILES['image']['name'][$i]} was successfully uploaded and added to the gallery<br />";

    }
    else
    {
     echo "There was an error uploading the file {$_FILES['image']['name'][$i]}, please try again!<br />";
    }
} // close your foreach

edit
Anda hampir sampai. Hapus kode duplikat di atas for loop. Hapus basename() , karena ini menyebabkan extension . Anda gagal, dan pathinfo() akan mengembalikan ['basename'] .

<?php
include($_SERVER['DOCUMENT_ROOT'] . "/connections/dbconnect.php");

for($i=0;$i<count($_FILES["image"]["name"]);$i++){
  if($_FILES["image"]["name"][$i] != ''){ // don't insert if file name empty
    $dataType = mysql_real_escape_string($_POST["dataType"][$i]);
    $title = mysql_real_escape_string($_POST["title"][$i]);

    $fileData = pathinfo($_FILES["image"]["name"][$i]);

    $fileName = uniqid() . '.' . $fileData['extension'];
    $target_path = $_SERVER['DOCUMENT_ROOT'] . "/images/gallery/" . $fileName;

    while(file_exists($target_path)){
       $fileName = uniqid() . '.' . $fileData['extension'];
       $target_path = $_SERVER['DOCUMENT_ROOT'] . "/images/gallery/" . $fileName;
    }     

  if (move_uploaded_file($_FILES["image"]["tmp_name"][$i], $target_path)){    // The file is in the images/gallery folder. 
    // Insert record into database by executing the following query:
     $sql="INSERT INTO images (data_type, title, file_name) "."VALUES('$dataType','$title','$fileName')";
     $retval = mysql_query($sql);

    echo "The image {$_FILES['image']['name'][$i]} was successfully uploaded and added to the gallery<br />
     <a href='index.php'>Add another image</a><br />";
  }
  else
  {
   echo "There was an error uploading the file {$_FILES['image']['name'][$i]}, please try again!<br />";
    }
  }
} // close your foreach
