消息为“ SQLSTATE [HY093]”的未捕获异常“ PDOException”。 我不明白怎么了
[英]Uncaught exception 'PDOException' with message 'SQLSTATE[HY093]. I don't understand what's wrong
问题描述
the backend part: 
后端部分：
$producttitle = $_POST['product-title'];
$price = $_POST['price'];
$category = $_POST['Category'];
$file = $_FILE['file_upload'];
$description = $_POST['description'];
$adq = "INSERT INTO Advertenties (Titel, Prijs, Categorie, Image, Beschrijving) VALUES (:product-title, :price, :category, :file_upload, :description);";
$query = $GLOBALS['$odb']->prepare($adq);
$results = $query->execute(array(
":product-title" => $producttitle,
":price" => $price,
":category" => $category,
":file_upload" => $file,
":description" => $description
));
Front end: 前端：
<?php
require_once('../classes/layout_shared.php');
?>
<html lang="NL">
<head>
<meta charset="UTF-8">
<link rel="stylesheet" href="../css/bootstrap.css">
</head>
<body>
<div class="container">
<div class="col-md-9">
<form method="POST" action="../classes/upload.php" class="ad-form" enctype="multipart/form-data">
<lable>Titel</lable>
<input class="form-control" type="text" name="product-title"/>
<lable>Bedrag/Bieden vanaf:</lable>
<input class="form-control" type="text" name="price"/><br>
<lable>Categorie</lable>
<input class="form-control" type="" name="category"/><br>
<lable>Image</lable>
<input class="form-control" type="file" name="file_upload"/> <br>

<textarea class="form-control" placeholder="Voeg een beschrijving van het product toe" name="description"></textarea></br>
<input type="submit" name="toevoegen" value="Toevoegen"/>
</form>
</div>
</div>
</body>
</html>
So, this is my code above. 所以，这是我上面的代码。 It's for some reason giving me an error but I just can't undertand why. 由于某种原因给我一个错误，但我无法理解为什么。 I've scoured the internet, and all I can find is something doesn't match something. 我搜寻了互联网，发现的所有东西都不匹配。 I've gone through this so many times, its starting to annoy me now. 我经历了这么多次，现在开始惹恼我。
Any ideas? 有任何想法吗？

When in doubt, break your query into as many lines as possible so that you can sniper the issue rather than having MySQL always report an error on line 1: 如有疑问，请将查询分成尽可能多的行，以便您可以狙击问题，而不是让MySQL始终在第1行报告错误：
Turn 转
$adq = "INSERT INTO Advertenties (Titel, Prijs, Categorie, Image, Beschrijving) VALUES (:product-title, :price, :category, :file_upload, :description);";
Into 成
$adq = "INSERT INTO Advertenties
(Titel,
Prijs,
Categorie,
Image,
Beschrijving)
VALUES
(:product-title,
:price,
:category,
:file_upload,
:description);";
Also, is :product-title a valid placeholder? 另外， :product-title是有效的占位符吗？

Beyond the sql placeholder name problem, you have multiple OTHER bugs: 除了sql占位符名称问题之外，您还有多个其他错误：
Field names are case sensitive: 字段名称区分大小写：
$category = $_POST['Category'];
^---
<input class="form-control" type="" name="category"/><br>
^----
$_FILES is an array of arrays: $ _FILES是一个数组数组：
$file = $_FILE['file_upload'];
":file_upload" => $file,
You can NOT bind array to a query placeholder. 您不能将数组绑定到查询占位符。 No idea what you're trying to do here - insert the actual file contents, or just the name of the file? 不知道您要在这里做什么-插入实际文件内容，还是仅输入文件名？ Either way, it should be something like 无论哪种方式，它都应该像
":file_upload" => $file['tmp_name'],
to bind only one particular value out of the array. 只能将一个特定值绑定到数组之外。

instead of having the array as a parameter for the execute function you should bind all the values separately using bindValue. 而不是将数组作为execute函数的参数，您应该使用bindValue分别绑定所有值。 If you passed them as a parameter every value would be treated as a string, with bindValue you maintain the type of the variable. 如果将它们作为参数传递，则每个值都将被视为字符串，使用bindValue可以维护变量的类型。 The code would look something like this: 代码看起来像这样：
$adq = "INSERT INTO Advertenties (Titel, Prijs, Categorie, Image, Beschrijving) VALUES (:product-title, :price, :category, :file_upload, :description);";
$query = $GLOBALS['$odb']->prepare($adq);
$query->bindValue(":product-title", $producttitle);
$query->bindValue(":price", $price);
$query->bindValue(":category", $category);
$query->bindValue(":file_upload", $file);
$query->bindValue(":description", $description);
$result = $query->execute();
I hope that this helps. 我希望这个对你有用。

looks like you have $category = $_POST[' Category ']; 看起来您有$ category = $ _POST [' Category ']; when you are sending 'category'. 当您发送“类别”时。 This is causing an undefined index. 这导致未定义的索引。 lowercase the c. 小写的c。 Along with Alex answer and you should be good 随着亚历克斯回答，你应该很好
