PHP-SQL-参数号无效:绑定变量数与令牌数不匹配

Question

此代码给出了以下错误:参数号无效:绑定变量数与令牌数不匹配

$fields[':email']=$_GET["email"];
$fields[':password']=$_GET["password"];
$fields[':telefono']=$_GET["telefono"];
$fields[':old_email']=$_GET["old_email"];
$fields[':isAdmin']=0;
$qry.="UPDATE utente SET Email:=email, Password:=password ,Telefono:=telefono, isAdmin=:isAdmin WHERE Email=:old_email";
$sth=$CONNESSIONE->prepare($qry);
$sth->execute($fields);

var_dump字段打印出来

array(5){[":email"] => string(5)"test2"[":password"] => string(1)"b"[":telefono"] => string(7)"0415600" [":old_email"] => string(4)"test"[":isAdmin"] => int(0)}

我的桌子就是这个

CREATE TABLE IF NOT EXISTS `utente` (
  `Email` varchar(150) COLLATE utf8_unicode_ci NOT NULL,
  `Password` varchar(150) COLLATE utf8_unicode_ci NOT NULL,
  `Telefono` varchar(150) COLLATE utf8_unicode_ci NOT NULL,
  `isAdmin` tinyint(1) NOT NULL,
  UNIQUE KEY `Email` (`Email`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

为什么这不起作用？

Answer 1

改变这一点

$qry.="Email:=email, Password:=password ,Telefono:=telefono, isAdmin=:isAdmin WHERE Email=:old_email";

至

$qry.="Email=:email, Password=:password ,Telefono=:telefono, isAdmin=:isAdmin WHERE Email=:old_email";

你错误地输入:前=
