PHP cannot upload multiple images - php

Question

I have a form in which I want to upload at most five images. The name and extension of the images are supposed to be inserted in the database table 'images' and then uploaded to the _uploads/name_of_the_album/ directory.
The problem is, when I choose some images and hit upload, only the first image is uploaded correctly, the other images fail.
Here is my code:
if(isset($_FILES['image']) === true){
$files = $_FILES['image'];
$allowed_ext = array('jpg', 'jpeg', 'png', 'gif');
$album_id = (int)$_GET['album_id'];
$album_name = $_GET['album_name'];
for($i=0; $i<count($files['name']); $i++){
$name = $files['name'][$i];
$tmp_name = $files['tmp_name'][$i];
$size = $files['size'][$i];
$ext = explode('.', $files['name'][$i]);
$ext = strtolower(end($ext));
$img_name = explode('.', $files['name'][$i]);
$img_name = strtolower(current($img_name));
//do some testing echos to see the result
//echo $img_name."<br>";
//here i'm going to add some validation as soon as
// i fix the multi-upload problem
//insert image into database
$query_insert_image = "INSERT INTO `images` (album_id, image_name, image_ext) VALUES ({$album_id}, '{$img_name}', '{$ext}') ";
$insert_image = mysql_query($query_insert_image, $connection) or die(mysql_error());
if(mysql_affected_rows() == 1){
move_uploaded_file($tmp_name, '../_uploads/'.$album_name.'/'.$name);
}
//redirect
redirect_to("view_album.php?succeed=1");
}//end the for loop
//echo '<pre>',print_r($files, true),'</pre>';
}
And here is some of the code of the form:
<form action="" method="post" enctype="multipart/form-data" name="formUploadImages" id="formUploadImages">
<p>
<label for="image">Choose one or more Image(s):</label><br />
<input type="file" name="image[]" id="image" /><br />
<input type="file" name="image[]" id="image" /><br />
<input type="file" name="image[]" id="image" /><br />
<input type="file" name="image[]" id="image" /><br />
<input type="file" name="image[]" id="image" />
</p>
......
Any ideas what I'm doing wrong?

Answer 1

I think you're cutting the branch from under your own feet.
redirect_to("view_album.php?succeed=1");
Redirecting means refreshing the page which means the end of execution. When that redirect is triggered after the first for loop ends and first image is uploaded the for will not continue to the next iteration.
And the fix of course is to push that line after the for loop (and never expect anything after a redirect to ever execute - unless the headers are already sent).
Most functions that do what redirect_to() does (it's not a core function it's based on another function header()) also make sure execution stops (have a line calling header() and another line calling die()/exit()).

Answer 2

try this php code ,working for me:
for($i=1;$i<6;$i++)
{
if(!empty($_FILES['image_upload'.$i])):
$target = "images/".$_FILES['image_upload'.$i]['name'];
$image_upload.= ",".mysql_real_escape_string(($_FILES['image_upload'.$i]['name']));
move_uploaded_file($_FILES['image_upload'.$i]['tmp_name'], $target);
endif;
}
create a folder in your root named "images" ,all the images will be moved in this folder.
html form may be looks like:
<form action="" method="post" enctype="multipart/form-data" name="formUploadImages" id="formUploadImages">
<p>
<label for="image">Choose one or more Image(s):</label><br />
<input type="file" name="image_upload1" id="image_upload1" /><br />
<input type="file" name="image_upload2" id="image_upload2" /><br />
<input type="file" name="image_upload3" id="image_upload3" /><br />
<input type="file" name="image_upload4" id="image_upload4" /><br />
<input type="file" name="image_upload5" id="image_upload5" />
</p>
......
this code is running on my end ,and after some editing as according to your needs may be useful for you.
Happy coding!

Answer 3

foreach($_POST['image'] as $report_id){
$sql="INSERT INTO images (album_id, image_name, image_ext) VALUES ('{$album_id}', '{$report_id}', '{$ext}') ";
$queryExe=mysql_query($sql);
}
replace this code in the place of your code after "//insert image into database" .

Answer 4

http://php.net/manual/en/features.file-upload.multiple.php
Read the Warning block 'Since PHP 5.2.12, the max_file_uploads configuration...'. Maybe that's the problem.
And there are some good examples and maybe You should use foreach instead of for.

Answer 5

1) Create a .htaccess file in the root folder of web server.
2) Put the following code in side the .htaccess file and save it.
php_value upload_max_filesize 20M
php_value post_max_size 20M
php_value max_execution_time 200
php_value max_input_time 200
Now you can upload the file-size up-to 20MB in a simple way using file field in your html form and move_uploaded_file() function available in PHP.
