当我提交表单时，我在 $_REQUEST 中收到数据，但未设置提交按钮 $_REQUEST["send-req"]。我在 $_REQUEST 和 $_POST 上使用了 var_dump，它正确显示了所有其他参数的值，但不包括“send-req”参数。

下面是“generic1submit.php”的代码

<?php

ob_start();
session_start();
if(!array_key_exists("clubloggedin", $_SESSION)){
    header("Location: ./index.php"); /* Redirect browser */
    exit;
}

require_once("../db.php");

if(isset($_REQUEST["send-req"]))
{
  $_SESSION["reqquantity"]= $_REQUEST["quantity"];
  $_SESSION["reqcolor"]= $_REQUEST["color"];
  $_SESSION["reqsize"]= $_REQUEST["size"];
  $_SESSION["reqdescription"]= $_REQUEST["description"];
  $target_dir = "requestuploads/";
  $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
  $imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
  $newname = "";
  $uploadOk = 1;
  $info = pathinfo($_FILES['fileToUpload']['name']);
  $ext = $info['extension']; // get the extension of the file
  $nameid = uniqid();
  $newname = $nameid.".".$ext; 
  $target = 'requestuploads/'.$newname;
  move_uploaded_file( $_FILES['fileToUpload']['tmp_name'], $target);
  $query="INSERT INTO club_requests(sports, category_id, product_id, quantity, color, size, description,club_id,filename) VALUES (\"{$_SESSION["sport"]}\",\"{$_SESSION["cid"]}\",\"{$_SESSION["pid"]}\",\"{$_REQUEST["quantity"]}\",\"{$_REQUEST["color"]}\",\"{$_REQUEST["size"]}\",\"{$_REQUEST["description"]}\",\"{$_SESSION["userdata"]["club_id"]}\", \"$newname\");";
  db::getInstance()->dbquery($query);
  header("Location: ../userhome.php");
  exit();
}


?>

这是request.js的代码

$(document).ready(function() {

    var scount = 0;
    $("#detail-form").submit(function(e) {
        if(scount==0)
        {
            e.preventDefault();
        }
        else{
            scount = 0;
            return true;
        }
        scount = 1;
        $("#exampleModalScrollable0").modal('show');
        $('#exampleModalScrollable0').on('hidden.bs.modal', function () {
            $("#detail-form").submit();    
        });
        
    });
});
