Question

对我来说一切似乎都很好，但表格不会在我的数据库中提交。我不知道还能做什么，我没有得到任何错误或任何东西，所以我真的很困惑。我错过了什么？这让我非常着迷

这是我的插入功能：

function insertDb($table, $data, $validation = null) {
    global $link;

    foreach($data as $key => $value) {
        $data[$key] = trim($value);
    }

    if(!empty($validation)) {
        foreach($validation as $field => $rules) {
            foreach($rules as $rule_type => $rule_value) {
                if($rule_type == 'unique') {
                    $check_exists = find('first', $table, array(array('field' => $field, 'operator' => '=', 'value' => $data[$field])));
                    if(!empty($check_exists)) {
                        $errors['error'][$field][$rule_type] = $field.' must be unique';
                    }
                } elseif($rule_type == 'min_lenght') {
                    if(strlen($data[$field]) < $rule_value) {
                        $errors['error'][$field][$rule_type] = $field.' requires at least ' . $rule_value . ' characters';
                    }
                }
            }
        }
        if(isset($errors)) {
            return $errors;
        }
    }

    foreach($data as $key => $value) {
        $insert_fields[] = $key;
        $insert_values[] = '"' . $value . '"';
    }

    $query = 'INSERT INTO ' . $table. ' ('.implode(',', $insert_fields).') VALUES ('.implode(',', $insert_values).')';
    mysqli_query($link, $query);

    return true;
}

所以这是主要代码。表格对我来说很好，我不知道这里出了什么问题

 <?php
    include "configuration.php";

    if(isset($_POST['submit'])) {
        $result = insertDb('products',
            array('category' => $_POST['name'],
                'name' => $_POST['name'],
                'price' => $_POST['price'],'active' => $_POST['active'],
                'condition' => $_POST['condition']));

        if($result === true) {
            header("Location: products.php");
        }
    }
    ?>

            <input type="submit" name="submit" value="Add">

        </form>
    </div>

我的产品表包含：

CREATE TABLE `products` (
                  `id` int(11) NOT NULL AUTO_INCREMENT,
                  `category` varchar(255) DEFAULT NULL,
                  `name` varchar(255) DEFAULT NULL,
                  `price` int(11) DEFAULT NULL,
                  `active` varchar(2) DEFAULT NULL,
                 `condition` varchar(2) DEFAULT NULL,
                  PRIMARY KEY (`id`)
                )

请检查数据库表的列大小。您已为活动列定义列大小，条件仅为2长度。但是当运行查询时，然后传递相应字段的值大小不止于此。另一个问题字段名称condition更改为任何其他名称。你不应该使用＆＃34; ＆＃34;对于整数类型字段也是。

表格不会在数据库中提交
