Question

我正在尝试使用PDO将数据插入到我的数据库中，但我收到的错误是“0结果”。我已经使用PDO从我的数据库中选择数据，但这是我第一次使用它来插入数据，所以对以下代码的任何帮助都将不胜感激！

我的表单：

<html>
<body>

<form name="blog post" action="insert.php" method="post">

<label for "id">Id: </label>
<input type="text" name="id">
<br>    
<label for "title">Title: </label>
<input type="text" name="title">
<br>    
<label for "year">Year: </label>
<input type="text" name="year">
<br>    
<label for "text">Text: </label>
<textarea rows="10" cols="50" name="text"></textarea>
<br>    
<button type="submit">Submit</button>
</form>

</body>
</html>

我的insert.php代码：

<?php

$pdo = new PDO('mysql:host=localhost;dbname=dbexample', 'userexample', 'paswexample', array(\PDO::MYSQL_ATTR_INIT_COMMAND =>"SET NAMES utf8;SET time_zone = 'Europe/London'"));

$sql = "INSERT INTO `tableexample` (id, title, year, text)
                                        VALUES (:id, :title, :year, :text)";
$stmt = $pdo->prepare($sql);
$stmt->bindParam(":id", $id);
$stmt->bindParam(":title", $title);
$stmt->bindParam(":year", $year);
$stmt->bindParam(":text", $text);

$form = $_POST;
$id = $form[ 'id' ];                    
$title= $form[ 'title' ];                   
$year= $form[ 'year' ];                 
$text= $form[ 'text' ];                 


$stmt->execute();

$result = $stmt->execute(array(':id'=>$id, ':title'=>$title, ':year'=>$year, ':text'=>$text));

if($result) {
    echo "Your text has been posted";

    }// end if
else {
    echo '0 results';
    }// end else

?>

Answer 1

替换它：

$stmt->execute();

$result = $stmt->execute(array(':id'=>$id, ':title'=>$title, ':year'=>$year, ':text'=>$text));

用这个：

$result = $stmt->execute();

或......仅限使用：

$result = $stmt->execute(array(':id'=>$id, ':title'=>$title, ':year'=>$year, ':text'=>$text));

并删除所有$stmt->bindParam

Answer 2

  try{
        $stmt = null;               
        $stmt = $conn->prepare("INSERT INTO mst_finish (id, title, year, text) VALUES (:title, ':year', :text)");       
        $data = array(              
            ':title' => ucwords($_REQUEST['title']),
            ':year' => strtoupper($_REQUEST['year']),
            ':text' => $_REQUEST['text']);
        $stmt->execute($data);
        $_SESSION['_msg'] = "Finish succesfully saved..!";
     }
     catch (Exception $e)
     {      
        $str= filter_var($e->getMessage(), FILTER_SANITIZE_STRING);         
        $_SESSION['_msg_err'] = $str;           
     }
