它似乎可以复制为this，但事实并非如此。由于同样的原因，this也不是我的情况。
这是我的form代码。
<form id="form-box" name="formName" action="notes-uploading.php" onSubmit="return validateForm()" method="POST" enctype="multipart/form-data">
<div class="sub-box" align="left">
<div class="sub-box-name">
<div class="box-num" align="center">1</div>
<div class="box-name">Notes Info</div>
</div>
<!-- Text [Name] -->
<input type="text" name="naam" class="sub-box-ip-txt" placeholder="Notes/Assignment Name*" required>
<!-- Select [Stream] -->
<select id="select-input" name="stream" required>
<option value="Wrong">Choose a stream</option>
<option value="Science & Engineering">Science & Engineering</option>
<option value="Business & Management">Business & Management</option>
<option value="Arts & Humanity">Arts & Humanity</option>
<option value="Architecture">Architecture</option>
<option value="Medical">Medical</option>
<option value="Law">Law</option>
<option value="Competition">Competition</option>
<option value="Others">Others</option>
</select>
<div class="error" id="slctErr"></div>
<!-- Text [Subject] -->
<input type="text" name="subject" class="sub-box-ip-txt" placeholder="Subject Name*" required>
<!-- Text [Topic Name] -->
<input type="text" name="topic" class="sub-box-ip-txt" placeholder="Topic Name*" >
<!-- Text [Course] -->
<input type="text" name="course" class="sub-box-ip-txt" placeholder="Course*" >
<!-- Text [Branch] -->
<input type="text" name="branch" class="sub-box-ip-txt" placeholder="Branch*" >
<span class="field-name">Upload Docs:</span>
<label id="upload-btn">
<input type="file" name="files[]" accept=".jpg, .png, .jpeg, .pdf, .ppt, .docx, .xlsx" id="img-upload" multiple>
<span class="upload-button"><i class="fa fa-upload"></i>Select Docs*</span>
</label>
<div class="error" id="uploadErr"></div>
<textarea form="form-box" name="description" class="text-area-input" placeholder="Description"></textarea>
<input type="submit" name="submit" class="submit">
</div>
</form>
以下是validateForm（）方法，因为它可能是问题的原因。
<script>
function validateForm(){
var checkForm;
/*Validating Select*/
var stream = document.forms["formName"]["select-input"];
var slctErr = document.getElementById("slctErr");
if(stream.value == "Wrong"){
slctErr.innerHTML = "Please select a stream";
checkForm = false;
}
else{
slctErr.innerHTML = "";
checkForm = true;
}
/*----Validating Image Upload----*/
var files = document.getElementById("img-upload").files;
var uploadErr = document.getElementById("uploadErr");
if(files.length > 20){
uploadErr.innerHTML = "Max 20 photos are allowed.";
checkForm = false;
}
else if(files.length == 0){
uploadErr.innerHTML = "Upload 1 or more photos.";
checkForm = false;
}
else{
uploadErr.innerHTML = "";
checkForm = checkForm && true;
}
return checkForm;
}
</script>
我在name的所有input字段中都有form个属性。
以下是我的notes-uploading.php页面代码段。
/*if someone tries to Direct access of this page*/
if($_SERVER["REQUEST_METHOD"] != "POST"){
die('Invalid Access: Page: notes-uploading.php; Line: 9');
}
浏览器打印出来。我删除了这一行，因此显示index未定义，即未收到数据。
问题出在哪里？为什么表单正在提交但不通过POST发送数据。
答案 0 :(得分：0)
你的checkForm何时返回true数据会发生什么？我没有看到任何函数捕获返回值并将数据发送到您的php我认为这可能是问题。
根据您的反馈，您的代码似乎是以任何方式进行连接，这与我对表单的处理方式有关，我使用单独的脚本进行验证，然后将收集的数据提交给php，将其添加到服务器。
通过这样做，数据将使用get事件提交，方法说POST看下面的2个代码并得到一个想法。

答案 1 :(得分：0)
好吧，我发现了这个错误。这是一个非常愚蠢的错误。我检查了我的数据库，数据就在那里，即数据上传，一切都很好。如果die函数在开头，那么为什么要上传data？
问题是我notes-uplaoding.php
/*Redirection after uploading*/
header("Location: notes-uploading.php");
问题是，我已经将header函数重定向到自身，即我正在访问我的页面两次，并且它第一次正常工作并上传数据，但在第二次访问时，它不是通过POST来的。
所以只需更改header函数的内容，我的问题就解决了。
