Multiple file upload in PHP - rename files

Solution:

You should allow multiple file selection in your file input, so you do not have to add a new input over and over again:

<input id="file" type="file" name="images[]" multiple>

After submitting the form you can iterate over$_FILES array like that:

foreach($_FILES['images'] as $file) {
    //your code here --> replace $_FILES['file'] with $file
}
Copy code

I hope this helps.

Solution:

<?php


if(isset($_POST['submit']))
{

    $count=count($_FILES["images"]["name"]);


for($i=0;$i<$count;$i++)
{   
  if ((($_FILES["images"]["type"][$i] == "image/gif")
 || ($_FILES["images"]["type"][$i]  == "image/jpeg")
|| ($_FILES["images"]["type"][$i]  == "image/pjpeg"))
&& ($_FILES["images"]["size"][$i] < 100000))
{

 if ($_FILES["images"]["error"][$i]  > 0)
 {
 echo "File Error : " . $_FILES["images"]["error"][$i]  . "<br />";
  }
  else 
 {
  echo "Upload File Name: " . $_FILES["images"]["name"][$i]  . "<br />";
 echo "File Type: " . $_FILES["images"]["type"][$i]  . "<br />";
  echo "File Size: " . ($_FILES["images"]["size"][$i]  / 1024) . " Kb<br />"; 

   if (file_exists("public/images/".$_FILES["images"]["name"][$i] ))
  {
   echo "<b>".$_FILES["images"]["name"][$i]  . " already exists. </b>";
   }
   else
  {
    move_uploaded_file($_FILES["images"]["tmp_name"][$i] ,"public/images/".             $_FILES["images"]["name"][$i] );
    echo "Stored in: " . "public/images/" . $_FILES["images"]["name"][$i] ."<br />";
   ?>
   Uploaded File:<br>
   <img src="public/images/<?php echo $_FILES["images"]["name"][$i] ; ?>" alt="Image path    Invalid" >
  <?php
  }
  }
  }else
 {
  echo "Invalid file detail ::<br> file type ::".$_FILES["images"]["type"][$i] ." ,    file    size

Copy code

In php

if(isset($_FILES['files'])){
    $errors= array();
    foreach($_FILES['files']['tmp_name'] as $key => $tmp_name ){
        $file_name = $key.$_FILES['files']['name'][$key];
        $file_size =$_FILES['files']['size'][$key];
        $file_tmp =$_FILES['files']['tmp_name'][$key];
        $file_type=$_FILES['files']['type'][$key];  
        if($file_size > 2097152){
            $errors[]='File size must be less than 2 MB';
        }       
        $query="INSERT into upload_data (`USER_ID`,`FILE_NAME`,`FILE_SIZE`,`FILE_TYPE`) VALUES('$user_id','$file_name','$file_size','$file_type'); ";
        $desired_dir="user_data";
        if(empty($errors)==true){
            if(is_dir($desired_dir)==false){
                mkdir("$desired_dir", 0700);        // Create directory if it does not exist
            }
            if(is_dir("$desired_dir/".$file_name)==false){
                move_uploaded_file($file_tmp,"$desired_dir/".$file_name);
            }else{                                  // rename the file if another one exist
                $new_dir="$desired_dir/".$file_name.time();
                 rename($file_tmp,$new_dir) ;               
            }
         mysql_query($query);           
        }else{
                print_r($errors);
        }
    }
    if(empty($error)){
