如何通过表单处理（PHP）访问下拉菜单中的值？

Question

I am having a hard time populating this country dropdown. How can the selected value be accessed when the form is submitted and processed in the controller?

<div class="form-group form-group-default">
<label class="">Country</label>
<select class="full-width select2-offscreen" data-placeholder="Select Country" data-init-plugin="select2" tabindex="-1" title="">
<?php if(isset($country)&&!empty($country)) {?>
<?php foreach($country as $count_id): ?>
<option value="<?php $count_id -> id;?>" name="country"> 
<?php echo $count_id -> name;?> </option>
</optgroup>
<?php endforeach; ?>
<?php } ?>
</optgroup>
</select>
</div>

Controller:

$profile -> country_id = $request -> country;

Answer 1

The name attribute should be on select element not on option element

Add name="country" attribute to select

<select name="country" class="full-width select2-offscreen" data-placeholder="Select Country" data-init-plugin="select2" tabindex="-1" title="">

And remove name attribute from option

<option value="<?php $count_id -> id;?>">
