如果 $_POST 值仍然相同,则 PHP 表单拒绝发送

我正在使用Range Sliders jQuery (picture),如果我没有每次都更改所有值,则表单不会发送,我不知道为什么。如果有人知道如何解决这个问题,即使修改单个值,表单也会发送。谢谢 :))


发送设置.php


<?php

if(isset($_POST['submit_range']))

{

    $temp_min_php=$_POST['temp_min_field'];

    $temp_max_php=$_POST['temp_max_field'];

    $hum_min_php=$_POST['hum_min_field'];

    $hum_max_php=$_POST['hum_max_field'];

    $eau_min_php=$_POST['eau_min_field'];

    $eau_max_php=$_POST['eau_max_field'];

    $lum_min_php=$_POST['lum_min_field'];

    $lum_max_php=$_POST['lum_max_field'];


    $conn = mysqli_connect("localhost", "root", "toor", "db");

    $query = "UPDATE settings SET temp_min = '$temp_min_php',temp_max = '$temp_max_php',hum_min = '$hum_min_php',hum_max = '$hum_max_php',eau_min = '$eau_min_php',eau_max = '$eau_max_php',lum_min = '$lum_min_php',lum_max = '$lum_max_php'";

    $result = mysqli_query($conn, $query);

}

?>

设置.php


            <script type="text/javascript">

            $(function() {

              $( "#temp-range" ).slider({

                range: true,

                min: 0,

                max: 500,

                values: [ <?php echo $row['temp_min']; ?>, <?php echo $row['temp_max']; ?> ],

                slide: function( event, ui ) {

                  $( "#temp_amount" ).html( ui.values[ 0 ]+ " °C" + " - " + ui.values[ 1 ]+ " °C" );

              $( "#temp_min_field" ).val(ui.values[ 0 ]);

              $( "#temp_max_field" ).val(ui.values[ 1 ]);

                }

              });

              $( "#temp_amount" ).html( $( "#temp-range" ).slider( "values", 0 )+ " °C" +

               " - " + $( "#temp-range" ).slider( "values", 1 )+ " °C" );

            });

隐藏输入的“值”属性仅在移动滑块时设置。您需要在此处设置初始值:<input type="hidden" id="temp_min_field" name="temp_min_field"><input type="hidden" id="temp_max_field" name="temp_max_field">像这样:<input type="hidden" id="temp_min_field" name="temp_min_field" value="<?php echo $row['temp_min']; ?>"><input type="hidden" id="temp_max_field" name="temp_max_field" value="<?php echo $row['temp_max']; ?>">
