Based on the information provided in the knowledge sources, there isn't a direct way to prefill repeatable fields with specific items as you've described. However, I can suggest a potential workaround that might help you achieve a similar result. The repeatable field in Backpack allows you to define a default number of rows or items when the field is first displayed. You can use the [
'name' => 'repeatablefield',
'label' => 'Repeatable Field',
'type' => 'repeatable',
'init_rows' => 3, // This will create 3 empty rows by default
'subfields' => [
// Your subfields here
]
]This approach will create empty rows, but it won't prefill them with specific values. To prefill the repeatable field with specific values, you might need to handle this in your controller. You could set the value of the field before the form is displayed. Something like this: CRUD::field('repeatablefield')->value(json_encode($yourPrefillData));Where However, it's important to note that this approach is not explicitly documented and might require some experimentation to get right. Another thing to keep in mind is that since Backpack v5, the repeatable field returns an array when the form is submitted, instead of a parsed JSON. You must cast the repeatable field to ARRAY or JSON in your model Backpack Docs. If you need more specific functionality, you might want to consider creating a custom field type that extends the repeatable field, allowing you to add the prefill functionality you need. Remember, when working with repeatable fields, you need to be cautious about using certain field types as subfields, as some may not work correctly within a repeatable context Laravel-Backpack/CRUD#2266.

Useful but doens't allow to specify some fields in the repeatable as disabled based on the input... |

With a lot of code I was able to do it, also I discovered that if a field is disabled the value isn't saved, switched to readonly. |

Yup @Mte90 - 100%, that's the difference between
If you ask me, the naming should be exactly the opposite in the HTML spec... but hey... it is what it is. -- If you can come back with the code that made it work for you, I'm sure it will help someone someday. And even if not, it might help our AI learn from it, so next time you ask, it'll know 😉 |
