<?php

//Сheck that we have a file

if((!empty($_FILES["uploaded_file"])) && ($_FILES['uploaded_file']['error'] == 0)) {

  //Check if the file is JPEG image and it's size is less than 350Kb

  $filename = basename($_FILES['uploaded_file']['name']);

  $ext = substr($filename, strrpos($filename, '.') + 1);

  if (($ext == "jpg") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") && 

    ($_FILES["uploaded_file"]["size"] < 350000)) {

    //Determine the path to which we want to save this file

      $newname = dirname(__FILE__).'/upload/'.$filename;

      //Check if the file with the same name is already exists on the server

      if (!file_exists($newname)) {

        //Attempt to move the uploaded file to it's new place

        if ((move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$newname))) {

           echo "It's done! The file has been saved as: ".$newname;

        } else {

           echo "Error: A problem occurred during file upload!";

        }

      } else {

         echo "Error: File ".$_FILES["uploaded_file"]["name"]." already exists";

      }

  } else {

     echo "Error: Only .jpg images under 350Kb are accepted for upload";

  }

} else {

 echo "Error: No file uploaded";

}

?>

when i try to upload any .jpg file under 350kb the last second error occur....I need ur suggestion that to run these code perfectly........

Re: file upload code.....need attention

Well, you have three conditions there that could be causing it to fall through

if (($ext == "jpg") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") && ($_FILES["uploaded_file"]["size"] < 350000)) {

Have you checked them all individually? This is just part of basic debugging. Use echo, var_dump(), or assert() statments to check these expressions individually.

Example of using assert()

<?php

// Active assert and make it quiet

assert_options(ASSERT_ACTIVE, 1);

assert_options(ASSERT_WARNING, 0);

assert_options(ASSERT_QUIET_EVAL, 1);



// Create a handler function

function my_assert_handler($file, $line, $code)

{

    echo "<hr>Assertion Failed:

        File '$file'<br />

        Line '$line'<br />

        Code '$code'<br /><hr />";

}



// Set up the callback

assert_options(ASSERT_CALLBACK, 'my_assert_handler');



$a=1;

$b=2;



// Make an assertion that should fail

assert ($a==$b);

 

?>
