Question

我有一份“html”表格,其中附有名为“形象”的文档,该图显示该法典的“网址”档案:

$date =  date( "Y_m_d_H_i_s_u" );

function upload() {

$info = pathinfo($_FILES[ image ][ name ]);
$target = "uploads/" . $date . $info[ extension ];

if(move_uploaded_file($_FILES[ image ][ tmp_name ], $target)) {
    return true;
} else{
    return false;
}
}

我希望档案名称有时间,而不是原始档案名称。我可以指出,为什么这赢得了工作! 所有上载的档案都称为延期。一些日子赢得工作。

Answer 1

Your scope is wrong for $date. You will want to either pass $date to your function or make it a global varible

$date =  date( "Y_m_d_H_i_s_u" );

function upload($date) {
    $info = pathinfo($_FILES[ image ][ name ]);
    $target = "uploads/" . $date . $info[ extension ];

    if(move_uploaded_file($_FILES[ image ][ tmp_name ], $target)) {
        return true;
    } else{
        return false;
    }
}

or

$date =  date( "Y_m_d_H_i_s_u" );

function upload() {
    global $date;
    $info = pathinfo($_FILES[ image ][ name ]);
    $target = "uploads/" . $date . $info[ extension ];

    if(move_uploaded_file($_FILES[ image ][ tmp_name ], $target)) {
        return true;
    } else{
        return false;
    }
}

Answer 2

$date is outside of the scope of your function. There are 2 ways to fix this:

Option 1

$date = date( "Y_m_d_H_i_s_u" );

function upload() {
    globel $date;
    $info = pathinfo($_FILES[ image ][ name ]);
    $target = "uploads/" . $date . $info[ extension ];

    if(move_uploaded_file($_FILES[ image ][ tmp_name ], $target)) {
        return true;
    }
    else{
        return false;
    }
}

Option 2

$date = date( "Y_m_d_H_i_s_u" );

function upload($date) {
    $info = pathinfo($_FILES[ image ][ name ]);
    $target = "uploads/" . $date . $info[ extension ];

    if(move_uploaded_file($_FILES[ image ][ tmp_name ], $target)) {
        return true;
    }
    else{
        return false;
    }
}

upload ($date);

Answer 3

您也可考虑返回<代码>move_uploaded_file。直接

return move_uploaded_file($_FILES[ image ][ tmp_name ], $target)

Answer 4

This is my observation , you are having scope issues

$date =  date( "Y_m_d_H_i_s_u" );

如果日期总是会发生变化

function upload() {
    $date =  date( "Y_m_d_H_i_s_u" );
    $info = pathinfo ( $_FILES [ image ] [ name ] );
    $target = "uploads/" . $date . $info [ extension ];
    if (move_uploaded_file ( $_FILES [ image ] [ tmp_name ], $target )) {
        return true;
    } else {
        return false;
    }
}

Option 1

Option 2
