重定向不能在PHP中工作

Question

I'm using jQuery autocomplete and trying to get it to go directly to the link when I click on suggestion or press enter. Here's the code I used:

        <script>
        $(function() {
        $( "#search" ).autocomplete({
        source: 'search.php',
        select: function(event, ui) {
         $(this).val(ui.item.value);
         $(this).parents("form").submit();  // this will submit the form.
   }
        });
        });
</script>

Then I have my php code for search: '

if ($_POST['search'] != null) {
                                //die("asdf: " . $_POST['search']);
                                $search = $_POST['search'];
                                $result = mysqli_query($con,"SELECT * FROM question WHERE text LIKE '%$search%'");
                                while($row = mysqli_fetch_array($result)) {
                                $text = $row['text'];
                                $question_id = $row['question_id'];
                                //die($search . " " . $text);
                                if ($search == $text){
                                    header("Location: http://localhost/showstats.php?question_id=$question_id");
                                    die();
                                }
                                echo "<br>";
                                echo " <a href=\"showstats.php?question_id=" . $question_id;
                                echo "\">$text</a> ";
                                //echo "<br>";
                            }}

The problem is when I click on suggestion it doesn't redirect to "showstats.php?question_id=$question_id", insted give me a blank result page. And when I insert die($search . " " . $text); inside if statement it's showing me text 2 times, so I know it enters the body of it statement.

When you select a suggestion, the event occurs in the client so this code in your PHP is not really necessary:

if ($search == $text) {
    header("Location: http://localhost/showstats.php?question_id=$question_id");
    die();
}

Instead, when you select a suggestion, try triggering the redirection from jQuery:

<script>
$(function() {
    $( "#search" ).autocomplete({
        source: 'search.php',
        select: function(event, ui) {
            // This will redirect you to whatever URL is in ui.item.value:
            window.location = ui.item.value;
       }
    });
});
</script>
