Characteristics Limit? was created by mohairbears
Hi,

I am trying to achive a product page that allows the buyer to select 4 colours from a choice of 34 colours, the way I have been trying is using 4 characteristic, i.e. colour 1, colour 2 etc. but this will not work with 4 options, it does work with just 2 options though? when options 3 & 4 are in the fields in the characteristics for those options are blank?

Hi,

You shouldn't use characteristics for that. the characteristic system creates one variant per combination of values of the characteristics. If you have 4 characteristics with 34 values each, that's 34*34*34*34 variants. Way too much to be processed by a normal server.
Instead, you should use custom fields on the table 'item' (business version). The limitation is that it will be displaying for all the products in your store which might not be what you're looking for. In that case, you can always change a bit the code of the show file of the view product to display them only for the products where you need them.

Yeah makes sense it is rather a lot of options, not php savvy though so what code would I need if the item page was called 'Multi-pack'

thanks

In that file you have the line:
if(!empty($this->itemFields)){

Suppose that your product has the code "multi_pack", you can change it to:
if($this->element->product_code=="multi_pack" && !empty($this->itemFields)){

Hi, works a treat except that the field 'label' shows on every item in checkout, I can leave the label blank but ':' still shows, can I prevent this?

thanks

In the file cart of the view checkout, you can check the line:
if(hikashop::level(2) && !empty($this->extraFields)){

to:
if($row->product_code=="multi_pack" && hikashop::level(2) && !empty($this->extraFields)){

In the email you have the line:
if(!empty($itemFields)){
that you can replace by:
if($item->product_code=="multi_pack" && !empty($this->itemFields)){

In the invoice, the items custom fields are not displayed.

In the order page details on the front end and on the back end (file show and form of the view order), you have the code:
if(hikashop::level(2) && !empty($this->fields)){
that you can replace by:
if($product->product_code=="multi_pack" && hikashop::level(2) && !empty($this->fields)){

Hi Nicolas,

When I change the code it also takes out the custom fields that are required to show?

Yes. You should not have required custom fields on the table item if you hide them because the system will refuse the operation on pages where you hide them

Hi sorry I do not mean as a required field but required to show.
The first screen dump shows what I want to show ringed in blue this is with the code

if(hikashop::level(2) && !empty($this->fields)){

if($product->product_code=="multi_pack" && hikashop::level(2) && !empty($this->fields)){ I get no itmes that I am after.

So you want to display the custom field value only if there is a value in it ?

In that case you need to add the line below in the foreach displaying all the custom fields:
if(empty($product->$namekey)) continue;
after the line:
$namekey = $field->field_namekey;
for example in the file form of the view order.

In the order creation email sent to the user, you have the code:
if(!empty($itemFields)){
foreach($itemFields as $field){
$namekey = $field->field_namekey;
echo '<p>'.$fieldsClass->getFieldName($field).': '.$fieldsClass->show($field,$item->$namekey).'</p>';
}
}
which handles the custom item fields display.

This is the code? this does not put the custom field value in the email, I have just inserted the line like you said and it will not work with or without?

<p><?php echo $item->order_product_name; ?></p>
<?php
if(!empty($itemFields)){
foreach($itemFields as $field){
$namekey = $field->field_namekey;
if(empty($product->$namekey)) continue;
echo '<p>'.$fieldsClass->getFieldName($field).': '.$fieldsClass->show($field,$item->$namekey).'</p>';

}
} ?>

That code is ALREADY in the email. So you should already see the custom fields.
Maybe you're using an old version of the email (the version number should be at the top of the email) ?

Using 1.4.7 the code is there yes, I have added this if(empty($product->$namekey)) continue; like you said.

So you want to display the custom field value only if there is a value in it ?

In that case you need to add the line below in the foreach displaying all the custom fields:
if(empty($product->$namekey)) continue;
after the line:
$namekey = $field->field_namekey;
for example in the file form of the view order.

Inserting this will not show the custom field data?

My code was an example...
As you can see, the product information comes from the variable $item in the email where that variable is called $product in other places.
So instead of using
if(empty($product->$namekey)) continue;
you should use:
if(empty($item->$namekey)) continue;
