Question

我的导航页面中有这个输入框和按钮

 form class="navbar-form"
 div class="form-group"
 form action="search.php" method="POST">
 input type="text" class="form-control" name="search"  
 placeholder="Search for Products..."
 input type="submit" value="Submit"
 /form
 /div
 /form

位于index.php页面的顶部和search.php中 $ output ='';

<!--collect -->
if(isset($_POST['search'])) {
    $searchQ = $_POST['search'];
    $searchQ = preg_replace("#[^0-9a-z]#i","",$searchQ);
    $query = mysql_query("SELECT * FROM products WHERE title LIKE 
    '%$searchQ%' OR part_number LIKE '%$searchQ%' OR stock_code LIKE 
    '%$searchQ%' OR form_factor LIKE '%$searchQ%' ") or die("could not 
    search!");
    $count = mysqli_num_rows($query);
    if($count == 0) {
        $output = '"There was no search results"';
    } else {
        while($row = mysql_fetch_array($query)) {
            $title      = $row['title'];
            $partNumber = $row['part_number'];  
            $stockCode  = $row['stock_code'];   
            $formFactor = $row['form_factor'];
            $id         = $row['id'];

            $output .= '<div>'.$title.' </div>';
        }
    }
}

当我点击按钮时，网址会从 http://localhost/alphacomponents.co.uk/index.php至http://localhost/alphacomponents.co.uk/index.php?search=Asus

我开发了工具，没有出现任何错误。有什么想法吗？

Answer 1

我想发表评论，但没有足够的声誉。

是问题，因为你在另一个表单中有一个表单？因此，您提交外部表格 - 这不是您要提交的表格？

您可以尝试下面的表单，然后检查它是否正确导航到search.php页面。

<form class="navbar-form" action="search.php" method="POST">
<div class="form-group">
    <input type="text" class="form-control" name="search" placeholder="Search for Products...">
    <input type="submit" value="Submit">
</div>

Answer 2

主要问题是网址从http://localhost/alphacomponents.co.uk/index.php转到http://localhost/alphacomponents.co.uk/index.php?search=Asus

应该转到http://localhost/alphacomponents.co.uk/search.php。

您需要删除嵌套表单。就这样说：

form class =＆＃34; navbar-form＆＃34;行动=＆＃34;的search.php＆＃34;方法=＆＃34; POST＆＃34;

搜索按钮不显示结果
