Question

我试图创建一个抽象模型，但我有一个错误这个abstract.php：

public function create()
    {
    global $connection;     
    $sql = 'INSERT INTO ' . static::$tableName .' SET '. self::buildNameParameterSQL();
    $stmt = $connection->prepare($sql);

    foreach(static::$tableSchema as $col=>$type){

        if($type == 4){
           $sanitizedValue = filter_var($this->$col, FILTER_SANITIZE_NUMBER_FLOAT, FILTER_FLAG_ALLOW_FRACTION);
           $stmt->bindValue(":{$col}", $sanitizedValue);
        }else{

            $stmt->bindValue(":{$col}", $this->$col, $type); // error here
        }

    }
    return $stmt->execute();
}`

这里是employee.php中我的班级员工，它扩展了这个抽象模型

require_once 'abstract.php';

cLass Employee extends AbstractModel
{

private $id;
private $name;
private $age;
private $address;
private $tax;
private $salary;


protected static $tableName = 'employees';
protected static $tableSchema = array (
    'name' => self::DATA_TYPE_STR,
    'age' => self::DATA_TYPE_INT,
    'address' => self::DATA_TYPE_STR,
    'tax' => self::DATA_TYPE_DECIMAL,
    'salary' => self::DATA_TYPE_DECIMAL
);
public function __construct($name, $age, $address, $tax, $salary){

    global $connection;

    $this->name = $name;
    $this->age = $age;
    $this->address = $address;
    $this->tax = $tax;
    $this->salary = $salary;

}

当我创建一个类employee的新对象并调用一个创建的方法

时

<?php
  require_once ('db.php');
  require_once ('employee.php');

  $emp = new Employee("abanoub", 21, "Cairo, Egypt", 1.03, 5000);
  var_dump($emp->create());

这是我的错误

Answer 1

似乎空格在错误的地方呈现

res - Strings

应为'name =: name, address =: address, salary =: salary, tax =: tax, age =: age'
