模糊标题的道歉。 我目前有一个编辑表单,可以在其中选择产品,并以可编辑的形式显示细节。不幸的是,编辑产品表中的每个产品时,都会编辑而不是仅选择产品。要选择我使用的产品,其中产品名称= productnameinput等等等等(代码如下所示)查询更新所有记录而不是与输入相匹配的记录?
数据库:http://prnt.sc/f4tf5g(编辑之前)
尝试添加以下语句的WHERE在更新查询的末尾:
UPDATE product SET CategoryID = :newCatId, ProductName = :newProdName, ProductDescription = :newProdDesc, stockCount = :newStock WHERE product.ProductName = :prodname
UPDATE product SET CategoryID = :newCatId, ProductName = :newProdName, ProductDescription = :newProdDesc, stockCount = :newStock WHERE ProductName = :prodname
PHP:
// edit product in database
$query="
SELECT * FROM category
";
$result = $DBH->prepare($query);
$result->execute();
$categories = $result->fetchAll();
//we need to select all products frist
$query3 = "
SELECT * FROM product
";
$result3 = $DBH->prepare($query3);
$result3->execute();
$allProducts = $result3->fetchAll();
//When the Product is selected this function is run
if (isset($_POST['choose'])) {
$query2 = "
SELECT product.*, category.* FROM product LEFT JOIN category ON category.CategoryID = product.CategoryID WHERE product.ProductName = :prodname
";
$result2 = $DBH->prepare($query2);
$result2->bindParam(':prodname', $_POST['product_name']);
$result2->execute();
$product = $result2->fetch();
}
//When the Update button is Pressed
if (isset($_POST['update'])) {
$query4 = "
UPDATE product SET CategoryID = :newCatId, ProductName = :newProdName, ProductDescription = :newProdDesc, stockCount = :newStock WHERE product.ProductName = :prodname
";
$result4 = $DBH->prepare($query4);
$result4->bindParam(':newCatId', $_POST['newcategory']);
$result4->bindParam(':newProdName', $_POST['productName']);
$result4->bindParam(':newProdDesc', $_POST['productDescription']);
$result4->bindParam(':newStock', $_POST['stockCount']);
$result4->bindParam(':prodname', $_POST['product_name']);
$result4->execute();
}
你需要一个'where'在'update'条款。 – chris85
现在就试试,谢谢。将更新问题,如果不成功,但我认为你是对的 – Xander
@ chris85很确定你是对的,但我仍然收到错误,我已更新我的问题。我应该包括$ post产品名称等吗? – Xander
