Question

此GET存在问题。我想传递三个值（ygo，dane，1）以及指向索引的链接，以便将这些值输入到相应的WHERE中。但是很遗憾，页面上没有任何价值，我只是不知道为什么。

控制器：

public function index($slug) {
    $url = 'edition/index';
    $array = explode ('/',$url);
    $data['array'] = $array[0];
    $data['title'] = 'Edition Liste';
    $data['edition_listes'] = $this->Edition_model->edition_listess($slug);
    $this->load->view('templates/header', $data);
    $this->load->view($url, $data);
    $this->load->view('templates/footer');
}
public function edition($tcg,$id,$short) {
    $url = 'edition/edition';
    $array = explode ('/',$url);
    $data['array'] = $array[0];
    $data['get_edition'] = $this->Edition_model->get_edition($tcg,$id,$short);
    $this->load->view('templates/header', $data);
    $this->load->view($url, $data);
    $this->load->view('templates/footer');
}

型号：

public function edition_listess($slug) {
    $this->db->select('*');
    $this->db->from('db_edition');
    $this->db->where('db_edition.tb_edition_tcg', $slug);
    $this->db->order_by('db_edition.tb_edition_kurzel', 'ASC');
    $this->db->order_by('db_edition.tb_edition_date', 'ASC');
    $query = $this->db->get();
    return $query->result_array();
}
public function get_edition($tcg,$id,$short) {
    $this->db->select('*');
    $this->db->from('db_edition');
    $this->db->where('db_edition.tb_edition_tcg', $tcg);
    $this->db->where('db_edition.tb_edition_id', $id);
    $this->db->or_where('db_edition.tb_edition_kurzel', $short);
    $this->db->order_by('db_edition.tb_edition_kurzel', 'ASC');
    $this->db->order_by('db_edition.tb_edition_date', 'ASC');
    $query = $this->db->get();
    return $query->result_array();
}

edition.php （测试页）

<?php echo validation_errors(); ?>
<?php echo $slug; ?>

Answer 1

您似乎没有将第三个参数传递给edition($tcg,$id,$short)。这可能意味着您的模型在对null的调用中使用$short作为$this->db->or_where('db_edition.tb_edition_kurzel', $short);的值，因此它可能不返回任何记录。

您的代码可能更容易阅读。这是有关如何创建指向版本控制器的链接的代码段建议

...
<div class="list-group">
    <?php
    $tcg = $edition_liste['tb_edition_tcg'];

    if($edition_liste['tb_edition_kurzel'] !== '') // use a more reliable test for an empty string than > ''
    {
        $id = $edition_liste['tb_edition_kurzel'];
    }
    else
    {
        $id = $edition_liste['tb_edition_id'];
    }

    $short = 1;
    ?>
    <a href="<?= base_url("edition/edition/$tcg/$id/$short"); ?>" class="list-group-item list-group-item-action list-group-item-secondary">
...

如果您不熟悉语法<?=与<?php echo完全相同，但键入量少得多。

现在，一个额外的建议。我不确定您为什么要使用此代码

$url = 'edition/index';

有一种方法可以获取当前的控制器和方法而无需对其进行硬编码。

$url = $this->router->class . '/' . $this->router->method;

这样，如果您重命名控制器或方法，则不必更改硬编码的字符串。是的！

CodeIgniter没有记录路由器类，但是源代码在/system/core/Router.php中，并且每个控制器都有一个路由器类的实例，其属性为$this->router。

GET将不会被发送
