Hey,

For a new little project of mine I want to be able to store certain things. Text and an image.

Storing the data is simple enough but what I want to do with the images is run a check to see that they are;

1. A certain dimension (150px X 150px)
2. A certain file type (gif)
3. Under a certain size (50kb maybe)

If all of these conform then I want the image name to be stored in the database and places in a folder designated especially for the images.

Say, just for example the fields would be;

Name (text)
Age (integer)
Location (text)
Image (location to the file images/filename1.gif)

I've tried looking at a script I found but don't fully understand it, I was wondering if someone could help me a little on this one

CODE

Send this file: <input name="userfile" type="file" />

CODE

$mime_type = array(1=>"image/jpeg", 2=>"image/gif", 3=>"image/jpg", 4=>"image/pjpeg");

if (is_uploaded_file($_FILES['userfile']['tmp_name'])) {
// you can change this if you move the uploaded file from the tmp folder.
$uploaddir = '/the/directory/here/uploads/'; // change this
$uploadfile = $uploaddir . $_FILES['userfile']['name'];
if(array_search($_FILES['userfile']['type'],$mime_type)){
if ($_FILES['userfile']['size'] > 100000) {
echo 'file size too large';
exit;
}

if (!copy($_FILES['userfile']['tmp_name'], $uploadfile)) {
echo "Possible file upload attack! Here's some debugging info:\n";
print_r($_FILES);
exit;
}
$new_mimetype = $_FILES['userfile']['type'];
} else {
echo "Wrong file type uploaded.";
exit;
}
} else {
echo "No file Uploaded, or file was empty";
exit;
}

Thanks!

I'm not sure how to do the dimension check Joe but if you just want to upload a file, make sure its an image, check its size and save it I've got this little snippet from my archive

PHP

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

Processing Page:
<?php
if (($_FILES["file"]["type"] == "image/gif") &&
($_FILES["file"]["size"] < 15000)) {
  echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
  echo "Uploading " . $_FILES["file"]["name"];
  echo " (" . $_FILES["file"]["type"] . ", ";
  echo ceil($_FILES["file"]["size"] / 1024) . " Kb).<br />";

  if (file_exists("uploads/" . $_FILES["file"]["name"])) {
    echo $_FILES["file"]["name"] . " already exists.  ";
    echo "Please delete the destination file and try again.";
  } else {
    move_uploaded_file($_FILES["file"]["tmp_name"],
    "uploads/" . $_FILES["file"]["name"]);
    echo "File has been stored in your uploads directory.";
  }

} else
  echo "Sorry, we only accept .GIF images under 15Kb for upload.";
?>

Basically just save the php bit as upload.php and the form will point to it. This one checks to make sure its a gif file which is less than 15Kb, it also checks that the file you are trying to upload doesn't already exist. its a little bit of modding I'm sure you can get it to do what you want. Not sure about dimensions though

I think there is a way in the GD library to output the dimensions... Actually I know there is...

Sorry about the late reply but I wasn't here before and just noticed when SJ responded.
