Image upload

[onthespot]

Hey guys, I am looking into allowing users to upload images to their profiles.

This function of course could be used anywhere on my site tha requires images.

 

So I need a user to be able to upload an image, and then it is displayed on their profile. The image should only be a certain size, 120 x 140 and a jpeg. And if a new image is uploaded, it should overwrite the previous one.

For the image resizing, would I just set the space I want the image to display to the size I want? Or is there a more effect method?

 

Quite confused about this, would appreciated it A LOT if someone could help me out here. Really don't know where to even begin!

Begin here.

Then move on to

If you want someone to write the script for you, post here

I have a question, atm, i have the following form.

 

<table>
<tr><td><form action="" method="POST">
<p><u>Create a News Piece</u>
<p>Subject:<input name="subject" type="text">
<p>Comment:<textarea name="comment" rows="4" cols="65" ></textarea>
<p><input type="submit" name="submit" value="Add News">
</form></tr></td>
</table>

 

I want to add a new input on the form for an image. However having read the above pages, it states the form must be

enctype="multipart/form-data"

.

 

If I add that to the above form, will it stop it working?

So this is what i have atm.

 

<table>
<tr><td><form action="" method="POST" enctype="multipart/form-data">
<p><u>Create a News Piece</u>
<p>Subject:<input name="subject" type="text">
<p>Comment:<textarea name="comment" rows="4" cols="65" ></textarea>
<p>Image: <input type="file" name="file" id="file" /> 
<p><input type="submit" name="submit" value="Add News">
</form></tr></td>
</table>

 

Thats the form to enter.

 

<?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";
  }
?> 

 

And thats the php for the uploaded image.

 

The image however, just wont upload. Doing absolutely nothing at all, although the rest of the form is working correctly.

Try

      if(move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . $_FILES["file"]["name"]))
      {
      echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
      }
else
      {
      echo "Could not upload";
      }
