I can't upload photos

Hello, I created file upload to insert product image but not work properly. I have followed the documentation but I don't know what is wrong. If you can help me with that I will appreciate it. I have a form that use any post to insert products. Something like name, price etc. Now I want to insert the product image into a folder. I use ProductImage as field which is type file so I can browse the image well. When I created the file upload I set it by default. I only assigned the variable name which is ProductImage and the folder where I want to upload the image. And I let it with any post. So I don't know what wrong. Please give your advice about that.

Make sure you have updated your <form> tag to include enctype="multipart/form-data" and also make sure you have updated the permissions on the folder you are uploading to to include full access for reading and writing.

That's I am missing. But I have tested in localhost. Do I need permission in localhost ?

Ok now is good. I can Save into the folder but now don't insert to the database. Do I need to change from post to file? So tell me do I have to update the insert too? I have something like $InsertQuery->bindColumn("ProductImage", "s", "".((isset($_POST["ProductImage"]))?$_POST["ProductImage"]:"") ."", "WA_DEFAULT");

Ok it's working. Thank you Ray. I appreciate your help. Thank you very much
