[SOLVED] how to uploadonly jpegs and gifs?

shadiadiph · December 21, 2008

this script is great but how would I make it so the form can only upload jpegs and gifs? At the moment it uploads any file type?

html form

<?

?>

<html>

<head>

</head>

<body>

Description:<br>

<br>File to upload:<br>

</form>

</body>

</html>

php page

<?php

include("global/connection.php");

include("global/mail.class.php");

error_reporting(7);

$data = addslashes(fread(fopen($form_data, "r"), filesize($form_data)));

$result=MYSQL_QUERY("INSERT INTO uploads (description, data,filename,filesize,filetype) ". "VALUES

('$form_description1','$data','$form_data_name','$form_data_size','$form_data_type')");

$id= mysql_insert_id();

print "<p>File ID: <b>$id</b><br>";

print "<p>File Name: <b>$form_data_name</b><br>";

print "<p>File Size: <b>$form_data_size</b><br>";

print "<p>File Type: <b>$form_data_type</b><p>";

print "To upload another file <a href=http://wwwwebsite.com/filetest.php> Click Here</a>";

?>

How would you like to check? Do you want to check the file extension of the potential image or do you want to read some of the image header to check?

mm i looked at that page funnily enough yesterday and couldn't get it to work just tried again with

if (!($userfile_type =="image/pjpeg" OR $userfile_type=="image/gif")){$msg=$msg."Your uploaded file must be of JPG or GIF. Other file types are not allowed<BR>";
$file_upload="false";}

changed userfile_type to form_data_type didn't work

I just want to allow the user to upload gifs and jpegs only I just tried the above and was able to successfully upload a word document?

Maybe this one will explain it in a way that is clearer to you

thanks blade works fine with this.

<?php 
include("global/connection.php");
include("global/mail.class.php");
error_reporting(7);

    if ((($_FILES["form_data"]["type"] == "image/gif")
|| ($_FILES["form_data"]["type"] == "image/jpeg")
|| ($_FILES["form_data"]["type"] == "image/pjpeg"))
&& ($_FILES["form_data"]["size"] < 250000))
  {
  if ($_FILES["form_data"]["error"] > 0)
    {
    echo "Error: " . $_FILES["form_data"]["error"] . "<br />";
    }
  else
    {

$data = addslashes(fread(fopen($form_data, "r"), filesize($form_data))); 
$result=MYSQL_QUERY("INSERT INTO uploads (description, data,filename,filesize,filetype) ". "VALUES 

('$form_description','$data','$form_data_name','$form_data_size','$form_data_type')"); 
$id= mysql_insert_id(); 
print "<p>File ID: <b>$id</b><br>"; 
print "<p>File Name: <b>$form_data_name</b><br>"; 
print "<p>File Size: <b>$form_data_size</b><br>"; 
print "<p>File Type: <b>$form_data_type</b><p>"; 
print "To upload another file <a href=http://www.hmtcompany.com/filetest.php> Click Here</a>"; 
    }
  }
else
  {
  echo "You can only upload JPEG or GIF images that are 250KB or less.";
  }


?>

You might be interested in this, just made it a few days ago!

<?php
// This is the temporary file created by PHP
$uploadedfile = $_FILES['uploadfile']['tmp_name'];
$uploadedfiletype = $_FILES['uploadfile']['type'];

if (!($uploadedfiletype =="image/pjpeg" OR $uploadedfiletype =="image/jpeg" OR $uploadedfiletype =="image/jpg")){
header ( "Location: uploadindex.php?stat=jpg" ); };


// Create an Image from it so we can do the resize
$src = imagecreatefromjpeg($uploadedfile);

// Capture the original size of the uploaded image
list($width,$height)=getimagesize($uploadedfile);
$height_orig = $height;
$width_orig = $width;

// For our purposes, I have resized the image to be
// 600 pixels wide, and maintain the original aspect
// ratio. This prevents the image from being "stretched"
// or "squashed". If you prefer some max width other than
// 600, simply change the $width_max variable

// maximum height and width
$width_max = "600";
$height_max = "800";

// initialize reduced dimensions
$heightr = $height_orig;
$widthr = $width_orig;

// if height exceeds max, scale down dimensions
if ($height_max < $heightr) {
$heightr = $height_max;
$widthr = ($height_max / $height_orig) * $width_orig;
}

// if width still exceeds max, further scale down dimensions
if ($width_max < $widthr) {
$heightr = ($width_max / $widthr) * $heightr;
$widthr = $width_max;
} 

$tmp = imagecreatetruecolor($widthr, $heightr); 

// this line actually does the image resizing, copying from the original
// image into the $tmp image
imagecopyresampled($tmp, $src, 0, 0, 0, 0, $widthr, $heightr, $width_orig, $height_orig); 

// now write the resized image to disk. I have assumed that you want the
// resized, uploaded image file to reside in the ./images subdirectory.
$filename = "images". $newname . ".jpg";
imagejpeg($tmp,$filename,100);

imagedestroy($src);
imagedestroy($tmp); // NOTE: PHP will clean up the temp file it created when the request
// has completed.

echo $width;
echo "<br>";
echo $height;
echo "<br>";

$imagesize= "../Gallery/Large/". $newname . ".jpg";

list($width2,$height2)=getimagesize($imagesize);

echo $width2;
echo $height2;

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
//watermark - passed onto another php file for a watermark to be placed on
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
header ( "Location: watermark.php?picid=" . $newname );
?>

mm thanks but my problem at the moment is i am only writing images to the sql database for easy indexing.

thanks anyway

lokie538 · December 22, 2008

Nah that wasnt to help with your current problem, that was a script for image resizing which you said you were going to look at next. You might need to resize the image before adding it too the database.

shadiadiph · December 22, 2008

thanks anyway everything i have tried isn't working so i am going to clear the page and start fresh if it hasn't worked in a hundred times start from scratch
