php - 我也尝试使用图像更新来更新我的数据，但是图像 isset 在 php 中不起作用

Question

嘿伙计们，我也创建了一个带有图像上传的注册表单，但是当我尝试更新此表单时，我尝试获取 ID，但我的图像的 isset 不起作用，所以它不会运行我的更新查询，请检查它出

这是更新表单，其中将显示所有值以供编辑，现在我可以在提交按钮的 isset 条件下运行更新功能，然后更新数据

    <title>Register Update</title>
<?php
//error_reporting(0);
$id=$_GET['id'];

function __autoload($classname)
{
include "$classname.php"; 
}
$obj = new connect();
$st=$obj->con();

if (isset($_POST['sub'])) 
{
$upd= new update();
$upd->updatedata($_POST);
}





$qry = "select * from register ";
$run = mysqli_query($st,$qry);
$row = mysqli_fetch_assoc($run);
 {
 $g = $row['gen'];
 $l = $row['lang'];
}


$query=mysqli_query($st,"select * from register where id='$id'");
//echo "<ul>";
while($query2=mysqli_fetch_assoc($query))
{
    //print_r($query2);
echo "<form method='POST' action='RegisterRetrieve.php'>";
echo "<table>";
?>

<p><input type="hidden" name="sid" value="<?php echo $query2['id']; ?>"></p>
<tr>
<td>
First Name:
</td>
 <td><input type="text" name="uname" value="<?php echo $query2['uname']; ?>"></td>

现在我正在使用我的更新查询，但是当我尝试设置我的图像时，它不会处于这种情况

    <?php

class update extends connect
{

    function updatedata($rel)
    {
        $obj= new connect();    
        $obj->con();


        extract($_POST);

        $id=$_GET['id'];

        $line = implode("," ,$lang);
        print_r($_POST);   


        if(isset($_FILES["file1"]))
        {

        extract($_POST);
        echo "hello";
        $name = $_FILES['file1']['name'];

        $type = $_FILES['file1']['type'];

        $size = $_FILES['file1']['size'];

        $tmp_name = $_FILES['file1']['tmp_name'];

        $loc = 'img/';

        $ext = substr($name,strpos($name,'.')+1);

        if($_FILES['file1']['size']>= '10000' || $_FILES['file1']['size']<="23000000")
        {
            //echo $size;
        }
            else{
            //  echo "size is not supported";
            }
        $val = $_FILES['file1']['size'];

         if($ext == 'jpg' || $ext == 'png')
            {
    //echo $lang;
    //print_r($_POST);
    //exit;
    $val =("update register set uname='$uname',pwd='$pwd',emailid='$emailid',gen='$gen',lang='$line',mobile='$mobile',10marks='$marks_10',12marks='$marks_12' file1='$name' where id=$sid");
    //print_r($qry);

    $res=mysqli_query($this->con(),$val);
    //print_r($run);
    if($res)
    {
            move_uploaded_file($tmp_name,$loc.$name);
            //echo "data saved";
        //echo "Data inserted";

        }
        else
        {
            //echo "Data Not Inserted";

            }

    }
}
}


        //print_r($val);

    //  return $res;
    }
?>

您的 html 已损坏:

</tr>
<?php

echo "<table>";    <--shouldn't this be </table>?
echo "</form>";
}
