I am going kinda crazy. I'm a newby to php but I'm getting the hang of it.

 

I'm having a problem with adding restrictions on multiple uploads. I want to make sure that they are "jpg" and "giff" only. and that they are not larger than 10 mb.  can you help please. this is what i have.

 

$path1= "upload/".$HTTP_POST_FILES['ufile']['name'][0];
$path2= "upload/".$HTTP_POST_FILES['ufile']['name'][1];
$path3= "upload/".$HTTP_POST_FILES['ufile']['name'][2];


copy($HTTP_POST_FILES['ufile']['tmp_name'][0], $path1);
copy($HTTP_POST_FILES['ufile']['tmp_name'][1], $path2);
copy($HTTP_POST_FILES['ufile']['tmp_name'][2], $path3);

echo "File Name :".$HTTP_POST_FILES['ufile']['name'][0]."<BR/>";
echo "File Size :".$HTTP_POST_FILES['ufile']['size'][0]."<BR/>";
echo "File Type :".$HTTP_POST_FILES['ufile']['type'][0]."<BR/>";
echo "<img src=\"$path1\" width=\"150\" height=\"150\">";
echo "<P>";

echo "File Name :".$HTTP_POST_FILES['ufile']['name'][1]."<BR/>";
echo "File Size :".$HTTP_POST_FILES['ufile']['size'][1]."<BR/>";
echo "File Type :".$HTTP_POST_FILES['ufile']['type'][1]."<BR/>";
echo "<img src=\"$path2\" width=\"150\" height=\"150\">";
echo "<P>";

echo "File Name :".$HTTP_POST_FILES['ufile']['name'][2]."<BR/>";
echo "File Size :".$HTTP_POST_FILES['ufile']['size'][2]."<BR/>";
echo "File Type :".$HTTP_POST_FILES['ufile']['type'][2]."<BR/>";
echo "<img src=\"$path3\" width=\"150\" height=\"150\">";


$filesize1=$HTTP_POST_FILES['ufile']['size'][0];
$filesize2=$HTTP_POST_FILES['ufile']['size'][1];
$filesize3=$HTTP_POST_FILES['ufile']['size'][2];

if($filesize1 && $filesize2 && $filesize3 != 0)
{
echo "We have received your files";
}

else 
{
echo "ERROR.....";
}



if($filesize1==0) <br />
{
echo "There was something wrong with your first file";
echo "<BR />";
}

if($filesize2==0) {
echo "There was something wrong with your second file";
echo "<BR />";
}

if($filesize3==0) {
echo "There was something wrong with your third file";
echo "<BR />";
}

?>

I'm not exactly familiar with that type of upload script, but this might work:

 

<?php

if($HTTP_POST_FILES['ufile']['type'] != "image/gif" || $HTTP_POST_FILES['ufile']['type'] != "image/jpg")
{
echo "You've tried to upload a disallowed file type.";
}
else
{
echo "succes";
}

?>

I am just going to change the script type. it throws me off as well, what I liked about it was that it showed me a thumbnail of the file after it was uploaded. with this line. echo "<img src=\"$path1\" width=\"150\" height=\"150\">";  but It's all a bit confusing.

 

this script worked well when I was uploading one file and it only allowed jpgs and giffs which was perfect. except that it wasn't showing me a thumbnail. can you help me make this into a a script that uploads multiple files, and shows me a thumbnail like the previous one.

 

here's the script that only allows me to upload one file at a time and under is the upload form I am using for multiple uploads: Thank you in advance.

 

<?php
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: " . $_FILES["file"]["tmp_name"];
  }
?> 
<?php
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 10000000))
  {
  if ($_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: " . $_FILES["file"]["tmp_name"];
    }
  }
else
  {
  echo "Invalid file";
  }
?> 
<?php
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 10000000))
  {
  if ($_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";
  }
?> 

// this is the upload file form that I am using

<form action=" upload_file.php " method="post" 

enctype="multipart/form-data">
  <strong>multiple Files Upload </strong> <br />
  <label for =”file”>File 1:</label>

<input type="file" name="file[]" id="file[]" size="50" />
</td>
<br />
<label for =”file”>File 2:</label>

</form>

Although I havent seen this before: $HTTP_POST_FILES['ufile']['name'][0] (probably new), but I am sure its a post form variable and you didn't define it, post form variables are lost when you refresh your page somewhere, so you need to write down your filenames somewhere after you uploaded and then recall it after you refresh the page:


<?php
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: " . $_FILES["file"]["tmp_name"];
  }
?> 
<?php
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 10000000))
  {
  if ($_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: " . $_FILES["file"]["tmp_name"];
    }
  }
else
  {
  echo "Invalid file";
  }
?> 
<?php
if ((($_FILES["file"]["type"] == "image/gif")

    if (file_exists("upload/" . $_FILES["file"]["name"]))
      {

      move_uploaded_file($_FILES["file"]["tmp_name"],

      echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
      file_put_contents("log.txt", "upload/" . $_FILES["file"]["name"]);//saved here

I am not sure about some of the redundant code though. :/[/code]
