Paypal & custom field

Hey fellas,

Question 1:

I succesfully added a custom field to the article layout. Currently it shows up on every article. I was wondering if it is possible to have a custom field added only to selected articles, or define if it should be added when creating an article ?

Question 2:

As you probably know paypal charges for each transaction, i was wondering if there is a way to add a certain amount (paypal ratio+fixed amount) so that it adds it to the final article price, resulting in the extra cost added covering the charge and the final received amount is the actual total product price and also make it clear that there is an extra cost when using the paypal payment option

Ok, custom field created for "product". However no option yet to define if a product should have it or not thats where your code change comes in ? I went to views but there's a ton of views. Don't know wich one(s) to edit.

Ok view edited, but for some reason i can't get the custom field to show up at all anymore on any article

Don't think i make myself clear. The client must be able to enter a some text in the mandatory field upon placing the order of the product. Reason is that the entered text will be the title of the delivered product. I want to be able to define which products i want that custom field to appear on. Not all them will.

The screenshot is like that because you said to create one in post 18474. Since i'm new to this could you say wich custom fields i need to create in which colums and what to modify. Just for the sake of clarity ill post it again. I need to be able to define which articles have the custom text field (not all of them will), but if it is visible, text input will be mandatory.

i'll post some ss's. Currently i have as followed (note GUI is in dutch)s
visible radio button on backend (mandatory to select if custom text field is needed)
custom field configured to have mandatory text input. However when radio is set to yes, field doesnt appear
item view has been modified with your code change

if(!$this->params->get('catalogue') && ($this->config->get('display_add_to_cart_for_free_products') || !empty($this->element->prices))){
       if(!empty($this->itemFields) && $this->element->custom_field_column_name=='yes'){

still doesnt work, tried also tried domeinnaam & domein: none of em show the text box. If click to have the "product" field 'domein' to show up on the front end then all it sais is "Ja" (dutch for yes). But thats not what i want, i want the text box

also tiny OT: what is "back end list" for ?

can't do that without setting the site to live, and it isnt ready yet. I can do a test account for ya. But can't find a way to pm you the details

done: title is my username & optional custom field. Template used is hs_hoster

omg, can't believe i overlooked that lol. i thought i was supposed to replace that 'Ja' lol. and the obvious clue was custom_field_column_name.
Also a few more things:

* how come it has to be 'domein' and not 'domeinnaam'. How does it work when the 2 field column names are different. I tried it at first with 2 identical names but it wouldn't save. There has to be some kind of link between the 2 fields that tells joomla that the radio button is specifically for that text field only. What if i created a second one. I'm trying to understand the mechanics about that in the event i want to add a 2nd text box i know what the communal link has to be

* where do i go to resize the template things inside the categories listing & on the final article display. Im mainly talking about that big white area

* is it possible to place restrictions on that newly created field. I need the users to be able to enter any alphabetical text but it has to end with eg: .be on other item's ill need that field to accept any alphabetical text but it has to end with anything BUT eg: .be
Is that possible ?

Sorry about that but thanks for fixing it


Final thing: whats that back end list for. Any special purpose ?

Anything ?

another reason i'm asking is that if i want to add another custom field i'd need to know how and what the common link should be
