最近，我尝试将一些包含文本和图像的记录插入到我的数据库中。虽然插入文本没有问题，但图像无法插入。我尝试插入的图像并不重。通常只有几 kb。 我的 .php 文件中是否犯了一些错误？
<?php
// php code to Insert data into mysql database from input text
if(isset($_POST['insert'])){
$hostname = "localhost";
$username = "root";
$password = "";
$databaseName = "database1";
// get values form input text and number
$fname = $_POST['fname'];
$contact1 = $_POST['contact1'];
$contact2 = $_POST['contact2'];
$filename = $_FILES['uploadfile']['name'];
$filetmpname = $_FILES['uploadfile']['tmp_name'];
$filename2 = $_FILES['uploadfile2']['name'];
$filetmpname2 = $_FILES['uploadfile2']['tmp_name'];
$folder = 'imagesuploadedf/';
$folder = 'imagesuploadedf2/';
move_uploaded_file($filetmpname, $folder.$filename);
move_uploaded_file($filetmpname2, $folder2.$filename2);
$connect = mysqli_connect($hostname, $username, $password, $databaseName);
// mysql query to insert data
$query = "INSERT INTO `tabela`(`name`, `imagename`, `imagename2`, `contact1`, `contact2`) VALUES ('$fname', '$filename', '$filename2', '$contact1', '$contact2')";
$result = mysqli_query($connect,$query);
// check if mysql query successful
if($result)
{
echo 'Data Inserted';
}
else{
echo 'Data Not Inserted';
}
mysqli_free_result($result);
mysqli_close($connect);
}
?>

最佳答案
请尝试

$contact2 = $_POST['contact2'];
$filename = $_FILES['uploadfile']['name'];
$filetmpname = $_FILES['uploadfile']['tmp_name'];
$filename2 = $_FILES['uploadfile2']['name'];
$filetmpname2 = $_FILES['uploadfile2']['tmp_name'];
$folder = 'imagesuploadedf/';
$folder2 = 'imagesuploadedf2/';
// edited and added below code. it will check if folder exists and create if not exists.....
$foldername = 'imagesuploadedf';
$foldername2 = 'imagesuploadedf2';
if ( ! is_dir($foldername)) {
mkdir($foldername);
}
if ( ! is_dir($foldername2)) {
mkdir($foldername2);
}
// end of edited and added code
move_uploaded_file($filetmpname, $folder.$filename);
move_uploaded_file($filetmpname2, $folder2.$filename2);
$connect = mysqli_connect($hostname, $username, $password, $databaseName);
// mysql query to insert data

是否已创建文件夹，即 imagesuploadedf 和 imagesuploadedf2 ？
在添加到数据库之前还要小心并清理输入数据。
