php pdo插入不'；不归

我正在尝试使用pdo将表单插入数据库。每次我点击submit，它似乎根本没有通过我的功能。我觉得我好像忽略了什么（两个小时了）

pdo连接工作（它在其他文件中工作）

我看不出我的错误。也没有任何警报得到回应

我觉得问题就在这里：

if（isset（$\u POST['insert']）{

或者用

在我看来，它们似乎是正确的

我们将非常感谢您的帮助

<form action="insertdata.php" method="post">

<div id="mainwrapper">
<input type="text" Placeholder="URL" name="url"><br>
<input type="text" Placeholder="Title" maxlength="40" name="title"><br>
<input type="textarea" Placeholder="Description" maxlength="200" name="description"><br>
<input type="text" Placeholder="Context" maxlength="25" name="location"><br>
<input id="submit" class="button" name="insert" type="submit" value="submit"></input>

<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

// php insert data to mysql database using PDO

if(isset($_POST['insert'])){

        echo '<script type="text/javascript">alert("test")</script>';


        // connect to pdo

    try{
        $pdoConnect = new pdo('pdo connection works correctly');
    }catch (PDOException $exc){
        echo $exc->getMessage();
    exit();
    }
    if(!$pdoConnect)
    {
        echo '<script type="text/javascript">alert("Oups")</script>';

    }

    // get values form input text and number
    $url=$_POST['url'];
    $title=$_POST['title'];
    $description=$_POST['description'];
    $location=$_POST['location'];
    // mysql query to insert data
    if($url=="")
    {
        echo '<script type="text/javascript">alert("You forgot something!")</script>';
    }

    $pdoQuery = "INSERT INTO `index` (`url`, `title`, `description`, `location`) VALUES (:url,:title,:description,:location)";



    $pdoResult = $pdoConnect->prepare($pdoQuery);

    $pdoExec = $pdoResult->execute(array(":url"=>$url,":title"=>$title,":description"=>$description,":location"=>$location));


        // check if mysql insert query successful
    if($pdoExec)
    {
        echo 'Thank you for submitting your website, you can now look for yourself';
    }else{
        echo 'Something went wrong, please contact us at a page we still need to make';
    }
}
?>
    </form>```

我复制了你的全部代码并运行了它。它运行得非常好

我认为您的表列数据类型有问题。请检查是否所有列都是text或varchar数据类型

这是您的代码：

<form action="index.php" method="post">

<div id="mainwrapper">
<input type="text" Placeholder="URL" name="url"><br>
<input type="text" Placeholder="Title" maxlength="40" name="title"><br>
<input type="textarea" Placeholder="Description" maxlength="200" name="description"><br>
<input type="text" Placeholder="Context" maxlength="25" name="location"><br>
<input id="submit" class="button" name="insert" type="submit" value="submit"></input>

<?php
/* Connect to an ODBC database using driver invocation */
$dsn = 'mysql:dbname=test;host=127.0.0.1';
$user = 'root';
$password = '';

try {
    $pdoConnect = new PDO($dsn, $user, $password);
} catch (PDOException $e) {
    echo 'Connection failed: ' . $e->getMessage();
}

if (!$pdoConnect) {
    echo '<script type="text/javascript">alert("Oups")</script>';

}

// get values form input text and number
$url         = $_POST['url'];
$title       = $_POST['title'];
$description = $_POST['description'];
$location    = $_POST['location'];
// mysql query to insert data
if ($url == "") {
    echo '<script type="text/javascript">alert("You forgot something!")</script>';
}

$pdoQuery = "INSERT INTO `index` (`url`, `title`, `description`, `location`) VALUES (:url,:title,:description,:location)";

$pdoResult = $pdoConnect->prepare($pdoQuery);

$pdoExec = $pdoResult->execute(array(
    ":url" => $url,
    ":title" => $title,
    ":description" => $description,
    ":location" => $location
));


// check if mysql insert query successful
if ($pdoExec) {
    echo 'Thank you for submitting your website, you can now look for yourself';
} else {
    echo 'Something went wrong, please contact us at a page we still need to make';
}

?>


</div>
</form>

我的表单有一个操作，该操作会重新加载页面，而不是运行php函数。我只需删除它。谢谢您的帮助

如果使用
if（isset（$\u POST['location']）{
会发生什么？这里也讨论了：@RobMoll注意到发生了有趣的事情。基本上是一样的。它是插入还是不回显“谢谢”/“出了问题”消息？@Edward它既不插入也不回显任何内容。感觉它所做的只是刷新页面。在
$pdoQuery
行之前添加此内容：
$pdoConnect->setAttribute（PDO:：ATTR\u ERRMODE，PDO:：ERRMODE\u异常）
OP指定的
“pdo连接工作正常”
隐藏其实际参数，以免泄露其用户id/密码等。
