也许您可以帮助我处理这部分代码。我试图让它工作，但是当我尝试 UPDATE 时，总是显示这个错误:
Warning: PDOStatement::execute() [pdostatement.execute]: SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens in /home/-----/public_html/soft/Admin/configuracion.php on line 264
第 264 行是:
// Execute the query
$stmt->execute();
以下:
$stmt->bindParam(':page_meta_tag', $_POST['page_meta_tag']);
$stmt->bindParam(':id', $_POST['id']);
这是我的代码:
<?php
include '../include/update_config.php';
$conn = new PDO("mysql:host=$dbhost;dbname=$dbname",$dbuser,$dbpass);
$action = isset( $_POST['action'] ) ? $_POST['action'] : "";
if($action == "update"){
try{
$query = "update CONFIGURACION set id = :id, nombre_clinica = :nombre_clinica, direccion = :direccion, telefono_clinica = :telefono_clinica, titulo_clinica = :titulo_clinica, logo = :logo, page_meta_tag = page_meta_tag where id = 1";
$stmt = $conn->prepare($query);
$stmt->bindParam(':nombre_clinica', $_POST['nombre_clinica']);
$stmt->bindParam(':direccion', $_POST['direccion']);
$stmt->bindParam(':telefono_clinica', $_POST['telefono_clinica']);
$stmt->bindParam(':titulo_clinica', $_POST['titulo_clinica']);
$stmt->bindParam(':logo', $_POST['logo']);
$stmt->bindParam(':page_meta_tag', $_POST['page_meta_tag']);
$stmt->bindParam(':id', $_POST['id']);
// Execute the query
$stmt->execute();
echo "Record was updated.";
}catch(PDOException $exception){ //to handle error
echo "Error: " . $exception->getMessage();
}
}
try {
//prepare query
$query = "select nombre_clinica, direccion, telefono_clinica, titulo_clinica, logo, page_meta_tag from CONFIGURACION where id = 1";
$stmt = $conn->prepare( $query );
//this is the first question mark
$stmt->bindParam(1, $_REQUEST['id']);
//execute our query
$stmt->execute();
//store retrieved row to a variable
$row = $stmt->fetch(PDO::FETCH_ASSOC);
$id = $row['id'];
$nombre_clinica = $row['nombre_clinica'];
$direccion = $row['direccion'];
$telefono_clinica = $row['telefono_clinica'];
$titulo_clinica = $row['titulo_clinica'];
$logo = $row['logo'];
$page_meta_tag = $row['page_meta_tag'];
}catch(PDOException $exception){ //to handle error
echo "Error: " . $exception->getMessage();
}
