enter image description here 

<?php
$email1 = $_SESSION['email'];
$Vendor_id = "SELECT Vendor_id FROM vendors where email = '$email1' ";
$result = mysqli_query($conn, $Vendor_id);
$row = mysqli_fetch_row($result);
$sql = "select Vendor_wallet_id, total_amount, request, amount, status, amt_pdflink from vendor_wallet";
$query = mysqli_query($conn, $sql);
?>

<form action="upload.php" method="post" enctype="multipart/form-data">
    <table id="example1" class="table table-bordered table-striped">
        <thead>
            <tr>
                <th>Transfer ID</th>
                <th>Request</th>

        <tbody>

            <?php
            while ($row = mysqli_fetch_array($query))
            {
                $cpid = $row['Vendor_wallet_id'];
                $tid = $row['request'];
                $type = $row['amount'];
                $pays = $row['status'];
                $amt = $row['amt_pdflink'];
                ?>
                <tr>    
                    <td value="<?php echo $cpid; ?>" name="cpid"><?php echo $cpid; ?></td>

您可以通过几种方式进行文件上传，其中一种方法是使表单成为单个表格单元格的子级，并将文件字段作为该表单的直接子级。保留布局的submit按钮不是表单的子项，需要更改为简单的button输入类型，然后使用javascript提交表单

<?php
    $email1 = $_SESSION['email'];
    $Vendor_id = "SELECT Vendor_id FROM vendors where email = '$email1' ";
    $result = mysqli_query($conn, $Vendor_id);
    $row = mysqli_fetch_row($result);
    $sql = "select Vendor_wallet_id, total_amount, request, amount, status, amt_pdflink from vendor_wallet";
    $query = mysqli_query($conn, $sql);
?>

    <table id="example1" class="table table-bordered table-striped">
        <thead>
            <tr>
                <th>Transfer ID</th>
                <th>Request</th>
                <th>Amount</th>
                <th>Status</th>
                <th>Upload</th>
                <th>Submit</th>
            </tr>
        </thead>
        <tbody>

<?php

    while( $row = mysqli_fetch_array( $query ) ) {
        $cpid = $row['Vendor_wallet_id'];
        $tid = $row['request'];
        $type = $row['amount'];
        $pays = $row['status'];
        $amt = $row['amt_pdflink'];
?>
    <tr>    
        <td value="<?php echo $cpid; ?>" name="cpid"><?php echo $cpid; ?></td>
        <td><?php echo $tid; ?></td>
        <td><?php echo $type; ?></td>
        <td><?php echo $pays; ?></td>   
        <td>
            <form action="upload.php" method="post" enctype="multipart/form-data">
                <input type="file" value="<?php echo $amt; ?>" name="fileToUpload" />
            </form>
        </td>   
        <td><input type="button" value="Submit" name="submit" /></td> 
    </tr>
<?php
    }
?>

        </tbody>
    </table>



<script>
    var bttns=Array.prototype.slice.call(document.querySelectorAll('input[type="button"][name="submit"]'));
        bttns.forEach(function(bttn){
            bttn.addEventListener('click',function(evt){
                this.parentNode.parentNode.querySelector('form').submit();
            }.bind(bttn),false );
        });
</script>

我有一些建议：

  1. 在“php.ini”文件中，搜索file_uploads指令，并将其设置为On：file_uploads = On
  2. ... </button><!-- <<-- How are you using this? -->
  3. 可以尝试回复$ amt;在循环的底部，看看路径是否正确。

  4. 可能想要检查$ amt是否为IF Empty条件/语句，并且可能检查其他变量的条件。

                $email1 = $_SESSION['email'];
            $Vendor_id="SELECT Vendor_id FROM vendors where email = '$email1' ";
            $result=mysqli_query($conn,$Vendor_id);
            $row = mysqli_fetch_row($result);
            $sql = "select Vendor_wallet_id, total_amount, request, amount, status, amt_pdflink from vendor_wallet";
            $query = mysqli_query($conn, $sql);
        ?>

             <form action="upload.php" method="post" enctype="multipart/form-data">

          <table id="example1" class="table table-bordered table-striped">

            <thead>
                <tr>

                    <th>Submit</th>
                </tr>
            </thead>
            <tbody>

            <?php

            while ($row = mysqli_fetch_array($query))
            {

在您的表单上

<?php
$email1 = $_SESSION['email'];
$Vendor_id = "SELECT Vendor_id FROM vendors where email = '$email1' ";
$result = mysqli_query($conn, $Vendor_id);
$row = mysqli_fetch_row($result);
$sql = "select Vendor_wallet_id, total_amount, request, amount, status, amt_pdflink from vendor_wallet";
$query = mysqli_query($conn, $sql);
?>

<form action="upload.php" method="post" enctype="multipart/form-data">
    <table id="example1" class="table table-bordered table-striped">
        <thead>
            <tr>
                <th>Transfer ID</th>
                <th>Request</th>
                <th>Amount</th>
                <th>Status</th>
                <th>Upload</th>
                <th>Submit</th>
            </tr>
        </thead>
        <tbody>

            <?php
            while ($row = mysqli_fetch_array($query))
            {
                $cpid = $row['Vendor_wallet_id'];
                $tid = $row['request'];
                $type = $row['amount'];
                $pays = $row['status'];
                $amt = $row['amt_pdflink'];
                ?>
                <tr>    
                    <td value="<?php echo $cpid; ?>" name="cpid"><?php echo $cpid; ?></td>
                    <td><?php echo $tid; ?></td>
                    <td><?php echo $type; ?></td>
                    <td><?php echo $pays; ?></td>   
                    <td><input type="file" name="fileToUpload []" class="fileToUpload" ></td> 
                    <input type="hidden" value="<?php echo $amt; ?>" name="fileToUploadLink []" class="fileToUploadLink" >
                    <td><input type="submit" value="Submit" name="submit" >
                        </button>
                    </td>  </tr>
            <?php } ?>

        </tbody>
    </table>
</form>

on upload.php 

<?php
 if(isset($_FILES['fileToUpload']['tmp_name'])&&isset($_POST['fileToUploadLink'])){
  for($i=0;$i<=(count($_FILES['fileToUpload']['tmp_name'])-1);$i++){
    move_uploaded_file($_FILES['fileToUpload']['tmp_name'][$i],$_POST['fileToUploadLink'][$i]);
  }

}

?>

好像你想要每行制作一个表格。

<tr>    
    <td value="<?php echo $cpid; ?>" name="cpid"><?php echo $cpid; ?></td>
    <td><?php echo $tid; ?></td>
    <td><?php echo $type; ?></td>
    <td><?php echo $pays; ?></td>   
    <td colspan="2">
       <form action="upload.php" method="post" enctype="multipart/form-data">
         <input type="hidden" name="Vendor_wallet_id" value="<?php echo $cpid;?>" />
         <input type="file" value="<?php echo $amt; ?>" name="fileToUpload" />
         <button>Submit</button>
       </form>
    </td>
</tr>
</form>

并删除包装表

的<form>标记
