Laravel can’t get the values from Vue-multiselect



I am using Vue-multiselect with Laravel.

I am using the multiselect component in my form to let the user select multiple countries. The component works fine but when I submit the form and I dd() it, it shows [object Object].

I can’t get the value of the multiselect component. I have found similar questions but none of them worked for me.

Here is my code:

The ExampleComponent.vue file:

<template slot-scope="{ option }">
<div>

<label class="typo__label">Restricted country</label>
<multiselect
          v-model="internalValue"
          tag-placeholder="Add restricted country"
          placeholder="Search or add a country"
          label="name"
          name="selectedcountries[]"
          :options="options"
          :multiple="true"
          track-by="name"
          :taggable="true"
          @tag="addTag"
          >
</multiselect>

<pre class="language-json"><code>{{ internalValue  }}</code></pre>

</div>
</template>

<script>
 import Multiselect from 'vue-multiselect'

  // register globally
  Vue.component('multiselect', Multiselect)

  export default {

  components: {
  Multiselect
  },
   props: ['value'],
   data () {
   return {
   internalValue: this.value,
   options: [
    { name: 'Hungary' },
    { name: 'USA' },
    { name: 'China' }
     ]
   }
 },
watch: {
internalValue(v){
this.$emit('input', v);
}
},
methods: {
addTag (newTag) {
  const tag = {
    name: newTag,
    code: newTag.substring(0, 2) + Math.floor((Math.random() * 10000000))
  }
  this.options.push(tag)
  this.value.push(tag)
  }
 },

 }
 </script>

Here is my register form:

<div id="select">
  <example-component v-model="selectedValue"></example-component>
  <input type="hidden" name="countriespost" :value="selectedValue">
 </div>
 
<script>
   const select = new Vue({
      el: '#select',
      data: {
         selectedValue: null
           },
         });
</script>

When I submit the form, the countriespost shows me me this: [object Object] instead of the actual value.

Answer

It’s because you are providing an array of objects as options property:

options: [
  { name: 'Hungary' },
  { name: 'USA' },
  { name: 'China' }
]

so the value emited on input is an object. Try to change the options to following:

options: [ 'Hungary', 'USA', 'China' ]
