in html if you do
<form action="" method="post">
<select multiple name="items[]">
<option value....
the post result will be an array. With vue, if you do
<input type="hidden" name="items[]" v-model="myArray">
you get back an array with one element containing a string "1,2,3". Essentially, v-model converts into a string on the post request. How can I get it to post an actual array?
This isn't the result of anything v-model is doing. Even in vanilla JavaScript/HTML, if you set an array value to an input and post it, you will get a string.
In order to post an array (without ajax) from <input>, you need multiple <input> with the same name:
<input
type="hidden"
name="items[]"
v-for="(item, index) in myArray"
:key="index"
:value="item"
/>
No need for v-model either since the input is hidden.
