如何在不使用blob的情况下上传图像

Question

我正在尝试根据用户的用户名上传图片 我的意思是你可以在图片中看到有一个叫做kunz的用户 因此，当用户kunz上传图片时，我希望它在kunz文件夹中

$username =getfield('username'); //function to get fields
$location = 'user/$username;  //this is the part that doesnt work

if (move_uploaded_file($tmp_name,$location.$name))
{
echo 'uploaded';
}else
    {
        echo 'there was an error';
    }

Answer 1

您的代码中似乎缺少某些内容。试试这个。

$username =getfield('username'); //function to get fields
$location = 'user/'.$username.'/';  //this is the part that doesnt work

if (move_uploaded_file($tmp_name,$location.$name))
{
echo 'uploaded';
}else
    {
        echo 'there was an error';
    }

Answer 2

首先确认$username不为空。然后修改您的代码，如下所示。

<?php

$username = getfield('username'); //function to get fields
if(!empty(trim($username)))
{
    $location = './user/'.$username;

    if ( ! is_dir($location)) // check if directory present or not
    {
        mkdir($location, 0755); // if director not present, create directory with proper permissions
    }

    // then upload the file to the folder
    if (move_uploaded_file($tmp_name,$location.'/'.$name))
    {
        echo 'uploaded';
    }
    else
    {
        echo 'there was an error';
    }
}
else
{
    echo "Error: Username empty.";
}
?>

每当你给目的地然后检查它是否可写和第二件事的位置，给出路径如下： -

$location='./user/'.$username.'/';

这样它应该从根文件夹中获取路径....

和

上传

move_uploaded_file($tmp_name,$location)

使用此声明。
