如何使用“ id”而不是“ name”发布HTML表单 [英] How to POST HTML form using `id` instead of `name`

问题描述

下面的代码将按名称获取元素，我将其更改为按ID获取元素，如何制作？

This following code will get element by name, I'm gonna change it to get element by ID, how to make it?

<?
if($_SERVER["REQUEST_METHOD"] == "POST" && array_key_exists("calculateFormSubmit", $_POST)) {
    $connectionData = ["server" => "","user" => "","pass" => "","database" => ""];
    $db = null;
    try {
      $db = new PDO("mysql:host=" . $connectionData["server"] . ";dbname=" . $connectionData["database"], $connectionData["user"], $connectionData["pass"]);
      $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    } 
    catch(PDOException $e) {
      echo $e->getMessage();
    }

    $dateFrom = (int)$_POST["YearBox"] . "-" . (int)$_POST["gmonth"] . "-" . (int)$_POST["gday1"];
    $dateTo = (int)$_POST["gyear2"] . "-" . (int)$_POST["gmonth2"] . "-" . (int)$_POST["gday2"];
    $stmt = $db->prepare("SELECT SUM(rialamount) as sum_result FROM problem_tbl WHERE opening_date BETWEEN STR_TO_DATE(:date_from, '%Y-%c-%e') AND STR_TO_DATE(:date_to, '%Y-%c-%e')");

    $stmt->bindValue(":date_from", $dateFrom);
    $stmt->bindValue(":date_to", $dateTo);
    $stmt->execute();
    $userData = $stmt->fetchAll(PDO::FETCH_ASSOC);

    if($userData != false) {
    foreach ($userData as $idPatient) {
            header('Content-Type: text/html; charset=utf-8');
            echo "<p>Text Here </p>\n";
            echo "<div id=\"rialamount\" style=\"text-shadow: 2px 2px 5px #0B4D09; font-size: 140%;\">\n";
            echo       "<b>" .  ['']  .        "<b> - "  . $idPatient["sum_result"] . "<br />";
            echo "</div>\n";
    }
    }

    if($db !== null) {
        $db = null;
    }
}
?>

在 $ dateFrom 和 $ dateTo 将通过类名称获取元素，如何更改它们以通过ID获取元素？

In the $dateFrom and $dateTo will get element by class name, How to change them to get element by ID ??

推荐答案

您无法通过ID检索php中的数据，因为它对名称有效。.所以您需要更改

you cant not retrieve data in php via ID it works on name..so you neeed to change

PHP

<form method="POST" action="nextpage.php" name="myform" id="myform">
    <input type="text" id="rout_markers"  name="rout_markers"/>
    <input type="hidden" name="someNewName" id="someNewName" value="" />
    <input type="submit" id="send-btn"  class="button" value="SEND NOW" onclick="submitform()" />
</form>

jQuery

$("form").bind('submit',function(e){
  e.preventDefault();
  var hiddenData=$("input[name=rout_markers]").val();
  // or var hiddenData=jQuery('#rout_markers').val(); 
  $("input[type=hidden][name=someNewName]").val(hiddenData);  
});

nextpage.php

以以下方式检索数据

$_POST['someNewName'];

更新

在提交按钮中设置 onclick = submitform（），并指定名称和 id 属性来形成并编写

Set onclick=submitform() in submit button and also assign name and id attribute to form and write this

javascript

<script type="text/javascript">
    function submitform()
    {
        var hiddenData = document.getElementById('rout_markers').value;
        document.getElementById('someNewName').value = hiddenData;
        document.myform.submit();
    }
</script>
