Hi everyone hope you are all well.
Guys I have the following php script, that currently is only 1-file-upload capable.
Id like to modify it so that it is mulit-file upload capable....let's say 5 at a time.

I have included the script in the code snippet.
Any help greatly appreciated.
=========================================== upload.php:
 

<!-- ******************************************************

HTML FORM SECTION:

*********************************************************** -->
 

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" enctype="multipart/form-data">

   <p>

      <label for="file">Select a file:</label> 

      <input type="file" name="userfile" id="file"><br />

      <input type="submit" value="Submit" />

   <p>

</form>
 
 

<!-- ******************************************************

UPLOAD SECTION:

*********************************************************** -->
 

<?php

      $allowed_filetypes = array('.jpg','.gif','.bmp','.png'); 					

      $max_filesize = 524288; 																

      $upload_path = './files/'; 															

 

   	$filename = $_FILES['userfile']['name']; 											

   	$ext = substr($filename, strpos($filename,'.'), strlen($filename)-1); 

 

  		if(!in_array($ext,$allowed_filetypes))

     		die('The file you attempted to upload is not allowed.');

 

   	if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize)

      	die('The file you attempted to upload is too large.');

 

   	if(!is_writable($upload_path))

      	die('You cannot upload to the specified directory, please CHMOD it to 777.');

   	

   	if(move_uploaded_file($_FILES['userfile']['tmp_name'],$upload_path . $filename))

         echo 'Your file upload was successful, view the file <a href="' . $upload_path . $filename . '" title="Your File">here</a>'; 

      else

         echo 'There was an error during the file upload.  Please try again.'; 

  

?>

Well, just duplicate the code for more instances of the file input boxes...

I've started to give you an idea of what I mean in the code snippet - just carry on doing the same - ie, make 4 more $ext{2...5} where you substitute $filename for the $filename2...#filename5 etc.

most importantly is the 4 extra "if" statements for each of the new files:

if(move_uploaded_file($_FILES['userfile2']['tmp_name'],$upload_path . $filename)){
}
if(move_uploaded_file($_FILES['userfile3']['tmp_name'],$upload_path . $filename)){
}
etc.

      <input type="file" name="userfile" id="file"><br />

<input type="file" name="userfile2" id="file"><br />

<input type="file" name="userfile3" id="file"><br />

<input type="file" name="userfile4" id="file"><br />

<input type="file" name="userfile5" id="file"><br />

may be you can try this also for multiple file uploads which requires flash

Hi psimation,
Thanks for that.
Is there any way instead of duplicating the code, to loop through files for multiple input boxes?

Yes, you could put the current code into a foreach loop and step through each $_POST variable to get the names of the form fields, but you would then need to call your file input boxes something unique/easy to check for, since $_POST will contain all form elements.

So, you could do something like this maybe:





foreach($_POST as $key=>$val) {
 

if (($val == "userfile1")||($val=="userfile2")||($val=="userfile3")||($val=="userfile4")||($val=="userfile5")){

$filename = $_FILES[$val]['name'];

$ext = substr($filename, strpos($filename,'.'), strlen($filename)-1); 

 

if(!in_array($ext,$allowed_filetypes))

 die('The file you attempted to upload is not allowed.');

 

if(filesize($_FILES[$val]['tmp_name']) > $max_filesize)

 die('The file you attempted to upload is too large.');

 

if(!is_writable($upload_path))

 die('You cannot upload to the specified directory, please CHMOD it to 777.');

       if(move_uploaded_file($_FILES[$val]['tmp_name'],$upload_path . $filename))

         echo 'Your file upload was successful, view the file <a href="' . $upload_path . $filename . '" title="Your File">here</a>'; 

      else

         echo 'There was an error during the file upload.  Please try again.';

}

}
