Question

这是我的以下代码：

$update = array(
                    'fullname' => $this->input->post('fullname'),
                    'phone' => $this->input->post('phone'),
                    'sex' => $this->input->post('sex'),
                    'city' => $this->input->post('city'),
                    if($_POST['bday']){ -->THIS FROM SUBMIT FORM
                        'bday' => $this->input->post('birthday')
                    }
);

如果有条件的话，有没有办法做到这一点？

Answer 1

只需将其附加到现有数组中，如：

$update = array(
 'fullname' => $this->input->post('fullname'),
 'phone' => $this->input->post('phone'),
 'sex' => $this->input->post('sex'),
 'city' => $this->input->post('city')                   
);

if($_POST['bday']){ 
    $update['bday'] = $this->input->post('birthday');
}

@Reynald Henryleo你可以这样做：

<?php
    $update = array(
                    'fullname' => $this->input->post('fullname'),
                    'phone' => $this->input->post('phone'),
                    'sex' => $this->input->post('sex'),
                    'city' => $this->input->post('city'),
                    'bday' => !empty($_POST['bday']) ? $this->input->post('birthday') : null
            );

    // if you don't want bday with null value then try below one

    $update = array(
                    'fullname' => $this->input->post('fullname'),
                    'phone' => $this->input->post('phone'),
                    'sex' => $this->input->post('sex'),
                    'city' => $this->input->post('city')
            );
    if(!empty($_POST['bday'])){
        $update["bday"] = $this->input->post('birthday');
    }

Answer 3

'city' => $this->input->post('city'),
'bday' => ($_POST['bday']) ? $this->input->post('birthday') : ''

如何在数组中使用if / else？
