I'm very new to Processwire.
I want to create a fieldtype where I can define multiple tags (all possible, not predefined ones).
I want to use them in my template as an simple array:
$tags = $page->get('tags');
// $tags = array('bananas', 'apples', 'oranges')
Because I'm creating a simple template which outputs my data as JSON for other apps. Somekind of a headless CMS.
How can i solve this? I did't found any processwire module or solution in other forums.
There are multiple way's to get this done. The easiest way obviously is to use a normal textfield and comma separate them. For your output you can just use
$tags = explode(',',$page->get('tags'));
If you want to have a nicer interface for inputting tags (output stays the same as above) you can use: http://modules.processwire.com/modules/textbox-list/
For more advanced solutions like using the "page" fieldtype and in addition "InputfieldChosenSelect" have a look here: https://processwire.com/talk/topic/2010-fieldtype-for-storing-tags/
Btw.: For Processwire the PW developer forum is always the best place to ask that kind of questions :)
