Question

我使用以下代码

我的控制器

public function index() {
        $pesan['title'] = 'Poster';

        /* form validation size & paper type */
        $this->form_validation->set_rules('quantityposter', 'Quantity', 'required');
        $this->form_validation->set_rules('priceposter', 'Price', 'required');

        if ($this->form_validation->run() == FALSE) {
            /* view */
        } else {

            $data['size'] = $this->input->post('sizeposter');
            $data['papertype'] = $this->input->post['papertypeposter'];
            $data['quantity'] = $this->input->post['quantityposter'];
            $data['harga'] = $this->input->post['priceposter'];

            $this->poster_model->daftar($data);
            redirect(site_url('home'));
        }
    }

我的模特

public function daftar($data) {         $this->db->insert('poster', $data);     }

我的表格

<form action="<?php base_url('poster') ?>" method="post" class="form-horizontal">
            /* size poster input */
            /* paper type poster input */
            <div class="form-group">
                <label for="quantityposter" class="col-sm-2">Quantity</label>
                <div class="col-sm-4">
                    <input type="text" class="form-control" onchange="fetch_quantity(this.value);" name="quantityposter" value="<?php echo set_value('quantityposter', '1'); ?>">
                </div>
                <p><?php echo form_error('quantityposter'); ?></p>
            </div>
            <div class="form-group">
                <label for="priceposter" class="col-sm-2">Price</label>
                <div class="col-sm-4" id="price">
                    <input type="text" name="priceposter" class="form-control" value="<?php echo "50000"; ?>">
                </div>
                <p><?php echo form_error('priceposter'); ?></p>
            </div>
            <br>
            /* submit input */

        </form>

我插入的数据成功，但是值为null？为什么呢？值有误吗？尺寸海报形式有效，但纸型，数量和harga为空？为什么？

问题似乎出在您的控制器上。

在您使用else语句之后

        $data['papertype'] = $this->input->post['papertypeposter'];
        $data['quantity'] = $this->input->post['quantityposter'];
        $data['harga'] = $this->input->post['priceposter'];

我认为一定是

        $data['papertype'] = $this->input->post('papertypeposter');
        $data['quantity'] = $this->input->post('quantityposter');
        $data['harga'] = $this->input->post('priceposter');

只需使用括号而不是括号。希望这会有所帮助！

为什么在codeigniter中插入表格后VALUE为NULL？
