<?php
$target_Folder = '/officework/php-startup/images/';
$uid = $_POST['id'];
$target_Path = $target_Folder.basename( $_FILES['uploadimage']['name'] );
$savepath = $target_Path.basename( $_FILES['uploadimage']['name'] );
$file_name = $_FILES['uploadimage']['name'];
if(file_exists('/officework/php-startup/images/'.$file_name))

}
$sql = "INSERT INTO directoryimage (id,image, image_name)

如果你的主文件相同的文件夹然后更新
$target_Folder = '/officework/php-startup/images/';
到
$target_Folder = 'officework/php-startup/images/';
那么这是你的总代码
<?php
$target_Folder = 'officework/php-startup/images/';
$uid = $_POST['id'];
$target_Path = $target_Folder.basename( $_FILES['uploadimage']['name'] );
$savepath = $target_Path.basename( $_FILES['uploadimage']['name'] );
$file_name = $_FILES['uploadimage']['name'];
if(file_exists('officework/php-startup/images/'.$file_name))
{
echo "That File Already Exisit";
}
else
{
// Database
$con=mysqli_connect("localhost","root","sal123","test"); //Change it if required
//Check Connection
if(mysqli_connect_errno())
{
echo "Failed to connect to database" . mysqli_connect_errno();
}
$sql = "INSERT INTO directoryimage (id,image, image_name)
VALUES ('','$target_Folder.$file_name','$file_name') ";
if (!mysqli_query($con,$sql))
{
die('Error: ' . mysqli_error($con));
}
echo "1 record added successfully in the database";
echo '<br />';
mysqli_close($con);
// Move the file into UPLOAD folder
move_uploaded_file( $_FILES['uploadimage']['tmp_name'], $target_Path );
echo "File Uploaded <br />";
echo 'File Successfully Uploaded to: ' . $target_Path;
echo '<br />';
echo 'File Name: ' . $_FILES['uploadimage']['name'];
echo'<br />';
echo 'File Type: ' . $_FILES['uploadimage']['type'];
echo'<br />';
echo 'File Size: ' . $_FILES['uploadimage']['size'];
}
?>

$sql = "INSERT INTO directoryimage (id,image, image_name)
VALUES ('','$target_Folder$file_name','$file_name') ";
将其更改为:
$sql = "INSERT INTO directoryimage (id,image, image_name)
VALUES ('','".$target_Folder."/".$file_name."','".$file_name."') ";
