php - 在 CodeIgniter 中内爆 Select2 表单中的多个值并插入到数据库

标签 php mysql codeigniter jquery-select2

我正在使用 select2 下拉列表中的多个选择，并且我想将从表单中选择的所有多个值存储在

数据库“xyz”

表名='pp_companies'

row="category1" <-- 需要此行是一个数组，其中包含 CSV 格式的选定值)

查看文件

<div class="titlehead">Courses Offered</div>
    <div class="input-group <?php echo (form_error('category1'))?'has-error':'';?>">
    <label class="input-group-addon">Category </label>
    <select name="category1" class="js-example-basic-multiple form-control" multiple="multiple">
      <option value="Engineering" <?php echo (set_value('category1')=='Engineering')?'selected':''; ?>>Engineering</option>
      <option value="Management" <?php echo (set_value('category1')=='Management')?'selected':''; ?>>Management</option>
      <option value="Law" <?php echo (set_value('category1')=='Law')?'selected':''; ?>>Law</option>
    </select>

一旦我提交表单，它仅发送从输入中选择的最后一个数据，在本例中为“法律”

        $return = $Q->result();
    } else {
        $return = 0;
    }
    $Q->next_result();
    $Q->free_result();
    return $return;
}


public function get_company_details_by_slug($slug) {
    $Q = $this->db->query('CALL get_company_by_slug("'.$slug.'")');
    if ($Q->num_rows > 0) {
        $return = $Q->row();
    } else {
        $return = 0;
    }
    $Q->next_result();
    $Q->free_result();
    return $return;
}

我知道，我必须在 Controller 中使用 implode 函数并将 name 属性放入数组中，即 = Category1[]，但我不太熟悉如何在这种情况下正确应用它，因为多次尝试执行此操作都导致 Controller 在页面中不显示任何内容。

如果我能得到一些帮助来解决这个问题，这会对我有很大帮助。

基本上，一旦将多个值插入数据库，我就会运行搜索和过滤器。

编辑 1:添加 Controller 和模型

最佳答案

试试这个

<div class="input-group <?php echo (form_error('category1'))?'has-error':'';?>">
<label class="input-group-addon">Category </label>
<select name="category1[]" class="js-example-basic-multiple form-control" multiple="multiple">
  <option value="Engineering" <?php echo (set_value('category1')=='Engineering')?'selected':''; ?>>Engineering</option>
  <option value="Management" <?php echo (set_value('category1')=='Management')?'selected':''; ?>>Management</option>
  <option value="Law" <?php echo (set_value('category1')=='Law')?'selected':''; ?>>Law</option>
</select>
