Image Upload

[Lamez]

I have never ever wrote a script to upload images, and I know this can be done.

 

Could someone write down the steps on getting a image to upload to a dir,  I have already set the chmode of the dir to 777. Also a sample code of a file upload or something like that would help me out. I do not want anyone to spoon feed me, I just need someone to point me in the right direction.

 

Thanks Guys

 

P.S. is it possible to set a image size, file size, and file extension.

Here is a script i have which creates a thumbnail image and a larger image and inserts the i image name into a database

 

<?php 
$idir = "../images/gallery/full/";   // Path To Images Directory 
$tdir = "../images/gallery/thumbs/";   // Path To Thumbnails Directory 
$twidth = "100";   // Maximum Width For Thumbnail Images 
$theight = "75";   // Maximum Height For Thumbnail Images 
$ldir = "../images/gallery/large/";   // Path To Thumbnails Directory 
$lwidth = "400";   // Maximum Width For Thumbnail Images 
$lheight = "300";   // Maximum Height For Thumbnail Images

$pic=($_FILES['imagefile']['name']);
$gallery = $_POST['gallery'];

if (!isset($_POST['gallery'])) {
?> 
<fieldset>
    <legend><b>Image Gallery Upload</b></legend>
<form enctype="multipart/form-data" action="<? $_SERVER['PHP_SELF']; ?>" method="post">  
    <p style="margin-left:10px;">Gallery to upload to:<br />
    <select name="gallery" size="1">
    	<option value="jack">Jack</option> 
    	<option value="honeylands">Honeylands</option> 
    	<option value="events">Events</option> 
    	<option value="art">Art Auction</option> 
    </select>
    	    <p style="margin-left:10px;">Image to upload:<br />
    	    <input type="file" name="imagefile" style="width:450px" /><br /> 
    	    <P><input type="submit" name="submit" value="Upload Image" class="submit-button" style="margin-left:10px;" /></p>
    	</form>
</fieldset><br />
