我应该返回什么值。
答案 0 :(得分:0)
如果您不需要返回任何值,请将返回类型更改为$sql_select = "SELECT * FROM tblproduct WHERE prodCat = '$selected_cat'";
。但如果缺少退货声明,那么你应该比我更清楚应该去哪里。也许您想要返回<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap Example</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

<style>
.form-control{
width:100px;
}
.form-control:focus{
width:400px;
outline:none;
transition: all 600ms cubic-bezier(.165, .84, .44, 1);
}
</style>
</head>
<body>
<div class="form-group">
<label for="email">Email:</label>
<input type="email" class="form-control" id="email" placeholder="Enter email">
</div>
</body>
</html>
,因为它不会在其他任何地方使用,并且与当前返回类型的类型相同。
