Solve : HTML file upload, size limit?

Answer»

Hey,
is there a method for the HTML file upload tool, that doesn't upload the file if its over a certain SIZE? or is it only in JS? HTML file upload tool?

HTML can't actually do the UPLOADING bit, only display the form.
 
The below is from here: http://www.w3schools.com/php/php_file_upload.asp
Fairly easy to understand and customise.

Code: [Select]<?php

if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 20000))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Error: " . $_FILES["file"]["error"] . "<br />";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br />";
    echo "Type: " . $_FILES["file"]["type"] . "<br />";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
    echo "Stored in: " . $_FILES["file"]["tmp_name"];
    }
  }
else
  {
  echo "Invalid file";
  }

?>

No it doesn't, it all goes in one single PHP or PHTML file... Quote from: macdad- on February 08, 2009, 03:51:49 PM

Well, you could use your normal HTML page to display the form, and put an action ATTRIBUTE in the form tag:
<form action="upload.php">...</form>so then i would put the could in a seperate php file with "action='upload.php'"?
Actually, the above example with only temporarily store the images, unless the tell it to store them.

This is the HTML file with the form to upload the file:

Code: [Select]<html>
<body>

<form action="upload.php" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>

</body>
</html>

And this is the PHP file, called upload.php, that actually uploads the file and stores in a folder.

Code: [Select]<?php
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 20000))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "RETURN Code: " . $_FILES["file"]["error"] . "<br />";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br />";
    echo "Type: " . $_FILES["file"]["type"] . "<br />";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

    if (file_exists("upload/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
      }
    }
  }
else
  {
  echo "Invalid file";
  }
?>

Does that explain it well enough? yup, Thanks Kpac  No problem.
