Form return values problem

psychowolvesbane · January 17, 2008

I have a form that has: multiple text/integer fields; a dynamically populated drop down list; a file upload; a static check button group; and a dynamically populated check button group. What i cannot seem to do is to get the form to keep the values for each input type once the form has been submitted, I can get the text and integer fields to return their values however it is the other types that I cannot deal with.

Here is the code, it is structured in validation then main code, the form is created twice, once for on first page load and a different form is created after submit has been pressed. I will deal with the "upload section" after this has all been sorted. I also return values for all fields, but I also have a slight image dimension restriction problem which means it still allows any .jpeg of any size to be accepted.

<?php

include "connect_details.php";

$CBSizes = array("XS","Small", "Medium", "Large", "XL", "XXL", "3XL");
$Submit = $_POST['SubmitB'];

if($_POST['SubmitB'] =="Submit")

   $ClothingCode = $_POST['ClothingCode'];

   $Description = $_POST['Description'];

   $Price1 = $_POST['Price1'];

   $ProductImage = $_FILES['ProductImage'];
   $Max_Size = 51200;
   $Img_Dimensions = getimagesize($_Files['ProductImage']['tmp_name']);

Check boxes require the phrase

checked="checked"

or just

checked

in the input code.

As for the file input, you can't define a value for that.

Okay I get that, but the problem is how do I make sure it only "Checks" the ones that have been checked before using the dynamically created check button groups?
