I want to send uploaded files address from html to php with array and then moved the uploaded files to images from tmp and checked their size

<form method="post" enctype="multipart/form-data" name="form1" id="form1" action="upload.php">
  <p>

    <input type="file" name="Img[]" />

    move_uploaded_file($_FILES[$files[]]['tmp_name'],'image/'.$name);
    echo "success";
}
?>

I want to upload files with form

Answer 1

Input file elements never store in the $_POST array. You have to loop through the $_FILES array to get the file elements

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

    for ($i=0; $i < count($_FILES['Img']['tmp_name']) ; $i++) {
      $name=rand('0123456789',5);
      if($_FILES['Img']['type'][$i]  == 'image/jpeg')
      {
        move_uploaded_file($_FILES['Img']['tmp_name'][$i],'image/'.$name . '.jpg');
      }
      echo "success";
    }
}

In this solution you can increase the number of input files with the same name as Img

Answer 2

Try this

<?php
if(isset($_POST['submit']))
  {

    foreach($_FILES['Img'] as $Img) {
      $name=rand('0123456789',5);
      if($Img['type']  == 'image/jpeg')
      {
        move_uploaded_file($Img['tmp_name'],'image/'.$name . '.jpg');
      }
      echo "success";
    }
}
?>
