Answer 1

请在您的计划中添加<form>标记，然后从form=implantForm删除<textarea>。此处我对您的代码进行了一些更改，然后我将textarea值作为输出

<form>
<table >
    <input type="hidden" name="ProtocolID" id="Protocol">
    <tr align="Left">
        <td>
            <label style="color:#ff6600;font-weight:bold">
                Name
            </label>
        </td>
        <td>
            <label id="formLbl"></label>
        </td>
    </tr>
    <tr align="Left" style="color:#ff6600;font-weight:bold">
        <td>Protocol  </td>
        <td>
            <textarea id="formTXT" rows="4" cols="50" name="Course_Descr" ></textarea>


        </td>
    </tr>

</table>

<table>
    <tr align="center" >
        <td>
            <input type="submit" name="saveEdites" value="Save changes">
        </td>

    </tr>
</table>
</form>
<?php
     if (isset($_REQUEST["saveEdites"])) {
        $id = $_REQUEST['ProtocolID'];
        $Course_Desc = $_REQUEST['Course_Descr'];
        $Course_Desc = trim($Course_Desc);
        $Course_Desc = stripslashes($Course_Desc);
        $Course_Desc = htmlspecialchars($Course_Desc);
        echo "Course Description Value is : ".$Course_Desc." ...Thanks";

    }
    ?>

Answer 2

<强>形式= “implantForm” 这让浏览器感到困惑 textarea值甚至没有在请求中发送。删除它，现在一切正常

Answer 3

请删除form =＆＃34; implantForm＆＃34;从textarea，然后它将工作。

无法在Request中获取TextArea值，始终为空
