Help With Image Upload

Hello,
I have a form like:

<form method="post" action="/admin/post.php">
<div style="width:650px;text-align:right;">
ID: <input type="text" name="id" value="1" /><br/>
Name: <input type="text" name="name" /><br/>
Category: <select name="category">
<option value="html">HTML</option>
<option value="wp">WP</option>

</select><br/>
Small Image:<input type="file" name="small_img_url" id="small_img_url" /><br/>
Big Image:<input type="file" name="big_img_url" id="big_img_url" /><br/>
HotFile: <input type="text" name="hotfile" value="" /><br/>
FileSonic: <input type="text" name="filesonic" value="" /><br/>
Easy-Share: <input type="text" name="easyshare" value="" /><br/>
Demo: <input type="text" name="Demo" value="" /><br/>
Active: <input type="radio" name="active" value="yes" checked>Yes <input type="radio" name="active" value="no">No
</div>
<textarea id="post" name="post" rows="15" cols="80" style="width: 100%"></textarea>
<input type="submit" value="Submit" name="save" />
</form>

HTML:

Where Small Image and Big Image are there is a file upload, I need the code for post.php that will post "Small Image" to /home/sharing/public_html/images/small/ (or http://example.com/images/small/ and post "Big Image" to /home/sharing/public_html/images/big/ (or http://example.com/images/big/

The Image file will be JPG, PNG or GIF, the image file name needs to be set by $small_image_name and $big_image_name.

Thanks
Chris

 

What you have tried so far?

 

first you need to add enctype="multipart/form-data"
to your form tag as it is necessary to upload the file via your post

 

it must be the enctype problem. I forget to add it all the time
google "php file upload" and you will get some good tutorials
