Question

这是一个在php中的注册页面，其中图像也与其他用户数据一起上传，但它总是显示错误，请帮助我找出问题。它总是显示失败，但我使用的是正确的图像。我还想知道如何在phpmyadmin中设置配置文件图像的默认值，以及当用户输入他的选择以及要使用插入查询插入数据库的其他用户数据时如何查询更新它。以及如何同时插入和更新插入和更新，即插入用户数据和更新默认图像。

<?php
include_once 'conn.inc';


if(isset($_POST["btnsave"])) {

    $filename=$_FILES['file']['name'];
    $size=$_FILES['file']['name'];
    $extenstion=pathinfo($filename,PATHINFO_EXTENSION);
    if($extenstion=='jpeg' || $extenstion=='png' || $extenstion=='jpg' && $size<=30000) {
        move_uploaded_file($_FILES["file"]["tmp_name"],
        "upload/" . $_FILES["file"]["name"]);

    }
     else {
        echo "failhhhhhhhhhh";
    }


    $name=mysql_real_escape_string($_POST["txtname"]);
    $fname=mysql_real_escape_string($_POST["txtfname"]);
    $gender=mysql_real_escape_string($_POST["gender"]);
    $image=$_FILES['file']['name'];
    $des=mysql_real_escape_string($_POST["des"]);
    $job=mysql_real_escape_string($_POST["txtjob"]);
    $country=mysql_real_escape_string($_POST["txtcountry"]);
    $state=mysql_real_escape_string($_POST["txtstate"]);
    $city=mysql_real_escape_string($_POST["txtcity"]);
    $contact=mysql_real_escape_string($_POST["txtcontact"]);
    $contactst=mysql_real_escape_string($_POST["contactst"]);
    $email=mysql_real_escape_string($_POST["txtemail"]);
    $emailst=mysql_real_escape_string($_POST["emailst"]);

    $query="insert into tblregistration values
    ('','$name','$fname','$gender','$image','$des','$job','$country','$state','$city','$contact','$contactst','$email','$emailst')" or die('neverve'.mysql_error());
    $res=mysql_query($query) or die('error 1'.mysql_error());
    if(mysql_affected_rows())
    {
        echo "success";
    }
    else {
        echo "failure";
    }
}
?>
