我正在做一个项目。哪里有你有护照的单选按钮。如果用户选择是，则会向用户显示其他文本框和上传护照图像的按钮，否则他们会隐藏。 我的问题是，当用户选择"is"并填写完整的详细信息时，它会正常工作，当用户选择“否”按钮或其他情况时，当用户选择"is"但未选择要上传的图像时，他/她在文本框中填写的数据不会“t 进入数据库。我将非常感谢这能消除我的错误。 我使用 BLOB 类型将图像直接存储在数据库中。 这是我的代码:
<?php
$conn = new mysqli("localhost","root","","db_dat");
$passno="";
$doi="";
$doe="";
$poi="";
if (isset($_POST['pass']))
{
$passno=$_POST['pass'];
}
if (isset($_POST['dateofissue']))
{
$doi=$_POST['dateofissue'];
}
if (isset($_POST['dateofexpiry']))
{
$doe=$_POST['dateofexpiry'];
}
if (isset($_POST['issueplace']))
{
$poi=$_POST['issueplace'];
}
if(isset($_POST['yeshave']))
{
$selectedValue =$_POST['yeshave'];
}
?>
<?php
//image script
if(isset($_POST['submit']) && $_FILES['userfile']['size'] > 0)
{
$fileName = $_FILES['userfile']['name'];
$tmpName = $_FILES['userfile']['tmp_name'];
$fileSize = $_FILES['userfile']['size'];
$fileType = $_FILES['userfile']['type'];
$fp = fopen($tmpName, 'r');
$image = fread($fp, filesize($tmpName));
$image = addslashes($image);
fclose($fp);
if(!get_magic_quotes_gpc())
{
$fileName = addslashes($fileName);
}
//imagescriptend
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "db_dat";
$conn=mysqli_connect($servername, $username, $password, $dbname);
$query = "INSERT INTO upload (name, size, type, image,passport_no,
dateofissue,dateofexpiry,placeofissue, having_passport ) ".
"VALUES ('$fileName', '$fileSize', '$fileType', '$image','"
.$passno."','".$doi."','".$doe."','".$poi."','".$selectedValue."')";
mysqli_query($conn,$query) or die('Error, query failed');
echo "<br>File $fileName uploaded<br>";
} //ifissetpost submit end
?>

最佳答案
因为我的图像和其他打开的文本框正在处理一个名称为 upload 的提交按钮，并且在我的图像脚本中我设置了 upload 。所以如果用户不选择图像，它就不能正常工作
