Question

我有一个班级，在那个班级里，我有一个方法像这样：

  public function insert($fields){
    //$fields is the array containing key and values like this
    // $fields['name'=>'name_field','city'=>'city_field'];

    //INSERT INTO table_name (name,city) VALUES (':name',':city')

    $sql = "";
    $sql .= "INSERT INTO table_name (".implode(',', array_keys($fields)).") VALUES ";
    $sql .=  "(':".implode("',':", array_keys($fields)).")";


    $stmt = $this->connect()->prepare($sql);


        //so here how can I bind parameters??


    $stmtExec = $stmt->execute();


}

就像我在上面的评论中所说，您应该使用foreach循环来遍历您的fields数组，然后bindValue。

这应该有效：

$fields = ['name'=>'name_field','city'=>'city_field'];

$implodeValue = implode(', ', array_keys($fields));
$implodeValuePlaceholder = implode(", :", array_keys($fields));

$sql = "INSERT INTO table_name ($implodeValue) VALUES (:".$implodeValuePlaceholder.")";
$stmt = $this->connect()->prepare($sql);

foreach ($fields as $key => $value) {
    echo $stmt->bindValue(':'.$key, $value);
}

$sql->execute();

现在这应该有效。

如何在PDO中绑定params？
