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"> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.0/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <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。
