【问题描述】：
我查看了stackoverflow，有很多这样的问题。但我似乎无法找到代码中缺少的内容。
Fatal error: Uncaught PDOException: SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens in C:\xampp\htdocs\backend\cases\traffic\traffic-insert.php:95 Stack trace: #0 C:\xampp\htdocs\backend\cases\traffic\traffic-insert.php(95): PDOStatement->execute(Array) #1 C:\xampp\htdocs\router.php(51): include_once('C:\\xampp\\htdocs...') #2 C:\xampp\htdocs\router.php(9): route('/traffic-insert', '/backend/cases/...') #3 C:\xampp\htdocs\routes.php(24): post('/traffic-insert', '/backend/cases/...') #4 {main} thrown in C:\xampp\htdocs\backend\cases\traffic\traffic-insert.php on line 95
解决此问题后出现此错误：
PHP AJAX - data update/edit inserts as new data instead of updating
代码如下：
<?php
include('./backend/config/connection.php');
include('./backend/config/function.php');
if( isset($_POST["traffic_operation"]) ) {
if( $_POST["traffic_operation"] == "Add" ) {
$traffic_doc = '';
if( $_FILES["traffic_doc"]["name"] != '') {
$traffic_doc = upload_image();
}
$statement = $connection->prepare('INSERT INTO traffic_violations (
plateNumber,
carModel,
carColor,
violationType,
ownerGender,
violationDateTime,
violationLocation,
workingShift,
violationAction,
violationStatement,
cccEmployee
) VALUES (
:plate_number,
:car_model,
:car_color,
:violation_type,
:owner_gender,
:violation_date,
:violation_location,
:working_shift,
:violation_action,
:traffic_doc,
:ccc_employee
)
');
$result = $statement->execute(
array(
':plate_number' => $_POST["plate_number"],
':car_model' => $_POST["car_model"],
':car_color' => $_POST["car_color"],
':violation_type' => $_POST["violation_type"],
':owner_gender' => $_POST['owner_gender'],

':working_shift' => $_POST['working_shift'],
':violation_action' => $_POST['violation_action'],
':traffic_doc' => $traffic_doc,
':ccc_employee' => $_POST['ccc_employee']
)
);
if( !empty($result) ) {
echo '<script>alert("Traffic Violation Added")</script>';
}
}
if( $_POST["traffic_operation"] == "Edit" ) {
$traffic_doc = '';
if( $_FILES["traffic_doc"]["name"] != '') {
$traffic_doc = upload_image();
} else {
$traffic_doc = $_POST['hidden_user_image'];
}
$statement = $connection->prepare('UPDATE traffic_violations SET
plateNumber = :plate_number,
carModel = :car_model,
carColor = :car_color,
violationType = :violation_type,
ownerGender = :owner_gender,
violationDateTime = :violation_date,
violationLocation = :violation_location,
workingShift = :working_shift,
violationAction = :violation_action,

cccEmployee = :ccc_employee,

);
$statement->execute(
array(
'id' => $_POST["violation_id"],

)
);
echo 'Traffic Violation Updated';
}
}
?>
【问题讨论】：
-
很多缺失的
:在像carModel = car_model,这样的行中应该是carModel = :car_model,所以它只是一个TYPO，奇怪的是第一列和最后一列是正确的，但所有中间是错的 -

@CBroe 如果您是英国人，那么它对您来说可能看起来像是简单的英语，但如果英语不是您的母语，则很难理解。诸如“绑定变量”和“令牌”之类的东西不会立即响起。 ADyson 写的要清楚得多。 PHP 错误消息可能非常深奥。

RiggsFolly 已经解释了您的问题。缺少
:s 使它看起来像您没有指定参数的 PDO，因此有关参数数量与变量数量不匹配的错误。这本来可以通过更仔细地研究其他人（工作）的 PDO 代码示例来解决……不过，自从 Riggs 发表评论后，您是否再次编辑了帖子？ -
另一个错字：
'id' => $_POST["violation_id"]缺少:。将其与所有其他人进行比较。并学会更仔细地仔细检查你的工作......注意细节是程序员的一项重要技能。
