getVar() from selected option input codeigniter 4 - codeigniter-4

Question

I have view
<!-- input-text -->
<div class="form-group">
<?php $name = 'name';
$placeholder = 'Nama Lengkap';
$value = old($name); ?>
<label for="<?= $name; ?>"><?= $placeholder; ?></label>
<input type="text" class="form-control <?= ($validation->hasError($name)) ? "is-invalid" : ''; ?>" id="<?= $name; ?>" name="<?= $name; ?>" placeholder="<?= $placeholder; ?>" value="<?= $value ?>">
<div class="invalid-feedback">
<?= $validation->getError($name); ?>
</div>
</div>
<!-- input-select -->
<div class="form-group">
<?php $name = 'gender';
$placeholder = 'Jenis Kelamin';
$value = old($name); ?>
<label for="<?= $name; ?>"><?= $placeholder; ?></label>
<select name="<?= $name; ?>" class="selectpicker form-control" data-live-search="true" id="<?= $name; ?>">
<option value="0">Laki-laki</option>
<option value="1">Perempuan</option>
</select>
</div>
and controller
public function create(){
dd($this->request->getVar());}
it show only name, but gender doesn't. How to show the value of selected option in CodeIgniter 4?

Answer 1

when you try to catch your post in controller u should type the name variable of the input
public function create(){
dd($this->request->getVar('gender'));
}

Answer 2

Use form helper, try it:
<div class="form-group">
<label for="name">Nama Lengkap</label>
<?php echo form_input('name', set_value('name'), 'class="form-control" placeholder="Nama Lengkap"'); ?>
<?php if(!empty($errors)){ ?>
<em class="text-danger"><?php echo $errors->getError('name') ?></em>
<?php } ?>
</div>
<div class="form-group">
<label for="gender">Jenis Kelamin</label>
<?php echo form_dropdown('gender', ['0' => 'Laki-laki', '1' => 'Perempuan'], [], 'class="form-control"'); ?>
</div>
Hope it helpful, cheers...
