私はこの問題を何時間も見つめています。私の人生のために、私は説明を見つけることができません。 PHPはuseridとsubgenre要素を見つけることができません。他のすべてが見つかりました。JSはJSまたはjQueryを使用して到達可能な要素をPHPが見つけることができないのはなぜですか？
HTMLフォーム
<form action="php/writers.php" method="post" enctype="multipart/form-data" target="upload-target" onsubmit="startUpload();" >
<h1>Writers</h1>
<p>
<input id="title" name="title" class="form-control" placeholder="Title" required autofocus="true" />
</p>
<p>
<label for="work-type" class="fixed50">Form:</label>
<select id="work-type" name="work-type">
<option value="fiction">Fiction</option>
<option value="non-fiction">Non-Fiction</option>
<option value="screenplay">Screenplay</option>
<option value="play">Play</option>
</select>
</p>
<p>
<p>For an explanation of the genres shown here, see <a target="_blank" href="https://en.wikipedia.org/wiki/List_of_genres">List of genres</a></p>
<label for="genre" class="fixed50">Genre:</label>
<select id="genre" name="genre">
</select>
</p>
<p>
<label for="subgenre" class="fixed50">Sub-Genre:</label>
<select id="subgenre" name="subgenre">`
<option value="0">None</option>
</select><br/>
</p>
<p>
<label for="nbrPages" class="fixed50">Number of pages:</label>
<input id="nbrPages" name="nbrPages" required style="width: 48px" placeholder="Pages" /><br/>
</p>
<p>For a limied time, writers can upload their sysnopsis or query letterr for <span style="color: #f00; font-weight:bold">FREE</span>. We reserve the right to change this policy without notice.</p>
<div id="tips">The objective of a sysnopsis or query letter is to entice enablers into requesting your manuscript.
It must be brief and to the point, now more than twp pages and, of course very well written.
</div>
<div class="form-group">
<p id="file-warning">Your synopsis or query letter must be a PDF file.
<a target="_blank" href="https://www.freepdfconvert.com/" target="_blank">Free file conversion to PDF</a></p>
</div>
<div class="form-group">
<label for="file2upload">PDF to Upload</label>
<input id="file2upload" name="file2upload" type="file" required value="File to upload" />
</div>
<div id="recaptcha-elements"></div>
<div class="form-group">

<input id="userid" name="userid" type="hidden" />
<iframe id="upload-target" name="upload-target" src="#" ></iframe>
</form>
次のJS関数は、コンソールに正しい値を書き込みます。
JS
function startUpload() {
$("#userid").val(window.localStorage.getItem('user-id'));
console.log("jquery val=" + $("#subgenre").val());
console.log("getElementById value=" + document.getElementById('subgenre').value);
showMessage(1, "Uploading...");
return true;
}
にconsole.log

ロード後に値が変更される可能性がある場合、phpはその値を選択できません。それはサーバー側のスクリプト言語です。 – Jain
私は***本当に***混乱しています、あなたは明確に定義されていない変数を持っています、エラーコードは、それがどんな行にあるのか、それがなぜエラーなのかを明示します。 – adeneo
正しく入力してみてください - > '$ userid = htmlspecialchars_decode（$ userrid、ENT_QUOTES）;' – adeneo
