need to adjust a code I have to work with hidden fields

[carag]

I'm building a form where staff can process quotes. I have a database with products and I need a button in the form to open a new window. In the new window you'd search for your product and choose it. Then I'd like to have a button when after I've clicked it, product code will be filled in the original form and the new window would close.

This is the code I have that I modified from a code that let you select a value from a select field. Unfortunately it doesn't work. I think the problem is in the head of the child file. I look forward to your comments.


parent file (parts of it):

//head:

<script type="text/javascript">
targetElement = null;
function addProduct(frm, id) {
  if(!frm || !id)
    return;
  targetElement = frm.elements[id];
  var handle = window.open('find_product.php');
}
</script>

//body:

<form id="frm" name="frm" action="#">
  <input name="code" type="text" id="code" size="10" />
  <input name="name" type="text" id="name" size="32" />
  <input type="button" value="Add Item" onclick="addProduct(this.form, 'code');" />
</form>

child file (parts of it):

//head:

<script type="text/javascript">
function addProduct(frm, id) {
  if(!frm || !id)
    return;
  var elem = frm.elements[id];
  if(!elem)
    return;
  var val = elem.options[elem.selectedIndex].value;
  opener.targetElement.value = val;
  this.close();
}
</script>

//body:

<form id="frm" name="frm" action="#">
  <input name="code" type="hidden" value="<?php echo $row_rsProducts['ProductID']; ?>" />
  <input name="name" type="hidden" value="<?php echo $row_rsProducts['ProductName']; ?>" />
  <input type="button" value="Add Product" onclick="addProduct(this.form, 'code');" />
</form>

Another thing that I'm not sure how to go round is that forms can't be nested so after the field is filled in, how can I submit the value? I'd like to use this same field for another form.

Too hard to tell what your code is trying to do. All I can even see are two forms and what appears to be useless JS bar opening a PHP file. Either way what you are after could easily be done with some PHP/simple JS by posting the results back to the page and probably using Ajax I guess to refresh it with the values. If you are taking code you're probably better off keeping it all in one file.

But yeah, this is a Java forum and not a JS/PHP forum so I think your thread will be closed.

the code is trying to post results back to the parent page. can you help me solve this?

this can't be done with php because it's server based. I need to open a new window, find results, post them back to the parent page and close the child window.
