在class.php和db.php中的PDO插入函数中形成表单数组

Question

I was wondering if you could help me with a problem when submitting a form to POST values and using a PDO Insert function to enter values into database. 我想知道在将表单提交给POST值并使用PDO插入函数将值输入数据库时是否可以帮助我解决问题。 Once someone can help me find the issue I will be able to use code over again in form areas. 一旦有人可以帮助我找到问题，我将能够在表单区域再次使用代码。 I have checked my $conn PDO statement and it is connected correctly to database just I can not insert the data from form. 我已经检查了我的$ conn PDO语句，它正确连接到数据库，只是我无法从表单中插入数据。

My coding layout: Form located in cust_form.php, names of form fields are as in database with the exception of an autoID generated upon insertion. 我的编码布局：表单位于cust_form.php中，表单字段的名称与数据库中的相同，但插入时生成的autoID除外。 Class.php is used to take POST values and to send to Insert function located in db.php. Class.php用于获取POST值并将其发送到位于db.php中的Insert函数。

db.php db.php中

<?php
//dbdt database class
if(!class_exists('dbdt')){
    class dbdt {

        //Connect and select database

        function connect() {
            try {
                require_once('config.php');
                    $conn = new PDO('mysql:host=localhost;dbname=displaytrends', $DB_USER, $DB_PASS);
                    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
                } catch(PDOException $e) {
                    echo 'ERROR: ' . $e->getMessage();
                }
        }

        //Connect to above
        function __construct() {
            $this->connect();
        }


        //Insert data into database

        function insert($conn, $table, $fields, $values) {
            try{
                $fields = implode(", ", $fields);
                $values = implode(", ", $values);

                $insert = "INSERT INTO $table (autoID, $fields) VALUES ('', $values)";
                $query = $handler->prepare($insert);
                $query->execute();
            } catch(PDOException $e) {
                    echo 'ERROR: ' . $e->getMessage();

You don't need to send "fields" parameters because if that array is in a different order than "values" your code won't work. 您不需要发送“字段”参数，因为如果该数组的顺序不同于“值”的顺序，则您的代码将无法工作。 Use the array keys from "values": 使用“值”中的数组键：

//Insert data into database

function insert($conn, $table, $values) {
    try {
        $keys = array_keys($values);
        $fields = implode(", ", $keys);
        $values = ":" . implode(", :", $keys);
        $insert = "INSERT INTO $table ($fields) VALUES ($values)";
        $query = $handler->prepare($insert);
        foreach ($values as $key => &$value) {
            switch(gettype($value)) {
            case 'integer':
            case 'double':
                $query->bindParam(':' . $key, $value, PDO::PARAM_INT);
                break;
            default:
                $query->bindParam(':' . $key, $value, PDO::PARAM_STR);
            }
        }
        $query->execute();
    } catch(PDOException $e) {
        echo 'ERROR: ' . $e->getMessage();
    }
}

Hope it helps. 希望能帮助到你。 I couldn't test it without complete code. 没有完整的代码，我无法测试。

PS: Avoid using prepare to execute SQL statements without using bindParam because you must to quote strings but not integers or floating point numbers. PS：避免在不使用bindParam的情况下使用准备执行SQL语句，因为您必须引号而不是整数或浮点数。
