Checklist inputName generation

[mix359]

Hi,

I'm trying to use the checklist in a form that will be submitted using standard html form request, and I'm facing a problem with the name generated for the checkbox inside the checklist.

With a normal html form you can send the values of some fields as array, setting their names to field[] or field[name]. That request is interpreted by PHP (I don't know the other languages) as an array of values, so it's easy to save the values of something like a multi-checkbox.
There's two types of array you can generate:

<input type="checkbox" name="columns[]" value="test1" /> <input type="checkbox" name="columns[]" value="test2" />

That would generate (if all the checkbox is checked) an array with ["test1", "test2"];

<input type="checkbox" name="columns[test1]" value="1" /> <input type="checkbox" name="columns[test2]" value="1" />

That would generate (if all the checkbox is checked) an array with ["test1" => 1, "test2" => 1];

I would like to use the first behavior to save some columns if their checked, but with the current way of generate the checkbox fieldName I can't. It currently generated as fieldName_checkboxName, and there require a processation in the backend to know which checkbox are selected.

I would ask if there's currently any option to obtain that fieldName/value combination, or if not, if I can send a PR that add the ability to use a lambda as inputName or option in checklistOptions, to generate the name of the internal checkbox.

Thanks
Cheers

What do you propose as an alternative to the existing logic? If you submit a PR, it would have to be backwards compatible with what we have configured now.

Sorry for the late reply (I was busy with a project...)

I've tried doing those two modification, that introduce new option, so it should be backwards compatible:

I've added the ability to pass a function in the checklistOptions, named inputName, that create the name of the field

getInputName(item){ if(this.schema && typeof this.schema["checklistOptions"] !== "undefined" && typeof this.schema["checklistOptions"]["inputName"] === "function") { return this.schema["checklistOptions"]["inputName"](item, this.schema); } else if(this.schema && this.schema.inputName && this.schema.inputName.length > 0){ return slugify(this.schema.inputName + "_" + this.getItemValue(item)); } return slugify(this.getItemValue(item)); },

I've added the :value proprieties to the input html tag, with the same value that is used by javascript when the field is checked.

input(:id="getFieldID(schema)", type="checkbox", :checked="isItemChecked(item)", :disabled="disabled", @change="onChanged($event, item)", :name="getInputName(item)" :value="getItemValue(item)")

That's is an example of function I've passed to the checklistOptions:
checklistOptions: {inputName: (item, schema) => schema.inputName + "[]"},

With those two modification, the form works as a standard html form and is decoded by php.
I've used a function, so anyone can use the format needed (for example, it can create the inputName as schema.inputName + "[" + schema.id + "]")

Hope those two change can be included in the package.
