Drupal removing a node reference from a node - drupal-6

Question

Ok, trying to process a script, both PHP and JavaScript, where I am moving a particular content type NODE from one reference to another. This is the structure:
I have a PROJECT
Inside each PROJECT are PAGES
Inside each PAGE are CALLOUTS
and Inside each CALLOUT are PRODUCTS.
What I want to do is take a PRODUCT from one CALLOUT to another CALLOUT. I am able to merge these, but now what I want to do is delete the first instance. An example:
I have PRODUCT AAG-794200 that is on PAGE 6 CALLOUT A. I am merging that PRODUCT with PAGE 6 CALLOUT B.
I can get the product to merge, but now I need to remove it from CALLOUT A. Here is my code:
$merge = explode(',', $merge); //Merge SKUs
$mpages = explode(',', $mpages); //Merge Pages
$mcallouts = explode(',', $mcallouts); //Merge Callouts
$mcallout_nid = explode(',', $mcallout_nid); //Merge Current callout
$length = count($merge);
$e = 0;
while ($e < $length) {
//Where is the SKU going to?
$to_callout_letter = strtoupper($mcallouts[$e]);
$to_page_num = $mpages[$e];
$sku = $merge[$e];
$from_callout = $mcallout_nid[$e];
//Where is the SKU coming from?
$other_callout = node_load($from_callout);
//Need page ID of current callout for project purposes
$page_nid = $other_callout->field_page[0]['nid'];
$page = node_load($page_nid);
//Need the project NID
$project_nid = $page->field_project[0]['nid'];
//We need to get the NID of the page we are going to
$page_nid = db_query('SELECT * FROM content_type_page WHERE field_page_order_value = "%d" and field_project_nid = "%d" ORDER BY vid DESC LIMIT 1', $to_page_num, $project_nid);
$page_nid_res = db_fetch_array($page_nid);
$to_page_nid = $page_nid_res['nid'];
//We need to get the NID of the callout here
$co_nid = db_query('SELECT * FROM content_type_callout WHERE field_identifier_value = "%s" and field_page_nid = "%d"', $to_callout_letter, $to_page_nid);
$co_nid_res = db_fetch_array($co_nid);
$to_callout_letter_nid = $co_nid_res['nid'];
//Load the present callout the SKU resides on
$f_callout = node_load($from_callout);
$callout = node_load($to_callout_letter_nid);
$long = count($f_callout->field_skus);
$deletecallout = array();
foreach($f_callout->field_skus as $skus) {
$s = 0;
while ($s < $long) {
if($skus['nid'] == $sku) {
$callout->field_skus[] = $skus;
$s++;
}
else {
$deletecallout[] = $skus;
$s++;
}
}
}
foreach($other_callout->field_images as $old_image) {
$callout->field_images[] = $old_image;
}
foreach($other_callout->field_line_art as $old_image) {
$callout->field_line_art[] = $old_image;
}
foreach($other_callout->field_swatches as $old_image) {
$callout->field_swatches[] = $old_image;
}
$callout->field_copy_text[0]['value'] .= $other_callout->field_copy_text[0]['value'];
$callout->field_notes[0]['value'] .= $other_callout->field_notes[0]['value'];
$callout->field_image_notes[0]['value'] .= $other_callout->field_image_notes[0]['value'];
$callout->field_status[0]['value'] = 'In Process';
node_save($callout);
This causes the PRODUCTS to MERGE, but not delete the original.
Thanks for any help. I know it's something simple, and it will be a palm-to-face moment.

I was actually able to solve this myself. #Chris - The brace ended after node_save(callout); I must have missed that when I copied and pasted. However, here is the code I ended up using:
$merge = explode(',', $merge); //Merge SKUs
$mpages = explode(',', $mpages); //Merge Pages
$mcallouts = explode(',', $mcallouts); //Merge Callouts
$mcallout_nid = explode(',', $mcallout_nid); //Merge Current callout
if($merge[0] !== '0') {
//Store NIDs of Old Callouts to the proper SKU
$oc_sku = array();
$oc_sku_e = count($merge);
$oc_sku_ee = 0;
while ($oc_sku_ee < $oc_sku_e) {
$curr_sku = $merge[$oc_sku_ee];
$curr_oldco = $mcallout_nid[$oc_sku_ee];
$oc_sku[$curr_sku] = $curr_oldco;
$oc_sku_ee++;
}
//Convert page numbers to page_nids
$pc = count($mpages); //How many pages are we getting
$pc_e = 0;
while($pc_e < $pc) {
$nid = $mpages[$pc_e];
$sql = db_query('SELECT * FROM content_type_page WHERE field_page_order_value = "%d" AND field_project_nid = "%d" ORDER BY vid DESC LIMIT 1', $nid, $project_nid);
$res = db_fetch_array($sql);
if($res) {
$npage_arr[] = $res['nid'];
} else { //If there is no page, we need to create it here.
$node = new StdClass();
$node->type = 'page';
$node->title = 'Page ' . $nid . ' of ' . $project->title;
$node->field_project[0]['nid'] = $project_nid;
$node->field_page_order[0]['value'] = $nid;
$node = node_submit($node);
node_save($node);
$npage_arr[] = $node->nid;
}
$pc_e++;
}
// Convert callout letters to callout_nids
$coc = count($mcallouts);
$coc_e = 0;
while($coc_e < $coc) {
$cnid = strtoupper($mcallouts[$coc_e]);
$pnid = $npage_arr[$coc_e];
$page_node = node_load($pnid);
$sql = db_query('SELECT * FROM content_type_callout WHERE field_identifier_value = "%s" AND field_page_nid = "%d" ORDER BY vid DESC LIMIT 1', $cnid, $pnid);
$res = db_fetch_array($sql);
if($res) {
$cpage_arr[] = $res['nid'];
} else { //If there is no callout that exists, we need to make it here.
$callout_node = new stdClass();
$callout_node->type = 'callout';
$callout_node->field_page[0]['nid'] = $pnid;
$callout_node->field_identifier[0]['value'] = $cnid;
$callout_node->field_sequence[0]['value'] = 0;
$callout_node->title = "Callout ".$callout." on page ".$page_node->field_page_order[0]['value'];
$callout_node->field_project[0]['nid'] = $project->nid;
$callout_node->field_wholesaler[0]['value'] = $project->field_wholesaler[0]['value'];
$callout_node->field_skus = array();
$callout_node->status = 1;
$callout_node->uid = 1;
$callout_node->revision = true;
$callout_node = node_submit($callout_node);
node_save($callout_node);
$cpage_arr[] = $callout_node->nid;
}
$coc_e++;
}
//Now we need to assign the skus to the appropriate callout for processing
$coc2 = count($cpage_arr);
$coc_e2 = 0;
while($coc_e2 < $coc2) {
$co = $cpage_arr[$coc_e2];
if($co !== '0') {
$sku = $merge[$coc_e2];

$oc_arr = array();

while($oc_e < $oc) {
$f_callout = $mcallout_nid[$oc_e];
$former_callout = node_load($f_callout);
foreach($former_callout->field_skus as $key=>$skus) {
$oc_arr[] = $skus;
}
$oc_e++;
}
//Now we are processing the Pages/Callouts/SKUs to save
$pc_e2 = 0;
foreach($m_arr as $key=>$values) {
$callout = node_load($key);
foreach($values as $value) {
$oc = count($oc_arr);
$oc_e = 0;
while($oc_e < $oc) {
$skus = $oc_arr[$oc_e];
if($value == $skus['nid']) {
$callout->field_skus[] = $skus;
//$nid = $oc_sku[$value];
$old_callout_info[] = $oc_sku[$value];

}
$callout->field_notes[0]['value'] .= $former_callout->field_notes[0]['value'];

$callout->field_logos = $former_callout->field_logos;

$callout->field_status[0]['value'] = 'inprocess';
node_save($callout);
$pc_e2++;
}
}
I realize this can probably be simplified in a way, but as for now, this works perfectly considering what I'm trying to do. No complaints from the client so far. Thanks for taking a look Drupal Community.
