我正在尝试编辑个人资料,但图片存在问题。
创建配置文件时,我可以成功上传图像,并在查看配置文件时查看图像。
但是,当我去编辑配置文件时,如果我不更改名称,年龄等值,则会将这些值写回具有未更改/原始值的数据库。
不幸的是,如果没有更改图像,单击编辑按钮时会被空白值覆盖。
我所追求的是一种说法:
IF $ FILES []为空 {
不要更新图片细节
}
ELSE
{
更新图片详情
}
我目前的代码如下:
// EDIT A PLAYER PROFILE
if (isset($_POST['action']) and $_POST['action'] == 'Edit' )
{
include $_SERVER['DOCUMENT_ROOT'] . '/includes/db.inc.php';
try
{
// $sql = 'SELECT id, name, age, position, height, weight, satscore, gpa FROM player WHERE id = :id';
$sql = 'SELECT player.id, player.name AS name, age, position, height, weight, previousclubs.id AS previousclubsid, GROUP_CONCAT(distinct previousclubs.name) previousclubs,
satscore, gpa, GROUP_CONCAT(distinct link) link, email, filename, mimetype, filedata
FROM player INNER JOIN playerpreviousclubs
ON player.id = playerid
INNER JOIN previousclubs
ON previousclubid = previousclubs.id
INNER JOIN links
ON links.playerid = player.id
WHERE player.id = :id';
$s = $pdo->prepare($sql);
$s->bindValue(':id', $_POST['id']);
$s->execute();
}
catch (PDOException $e)
{
$error = 'Error fetching profile details.' . $e->getMessage();
include 'error.html.php';
exit();
}
$row = $s->fetch();
$pageTitle = 'Edit Profile';
$action = 'editform';
$name = $row['name'];
$age = $row['age'];
$position = $row['position'];
$height = $row['height'];
$weight = $row['weight'];
$satscore = $row['satscore'];
$gpa = $row['gpa'];
$previousclubs = $row['previousclubs'];
$previousclubsid = $row['previousclubsid'];
$link = $row['link'];
$email = $row['email'];
$filename = $row['filename'];
$mimetype = $row['mimetype'];
$filedata = $row['filedata'];*/
$id = $row['id'];
$button = 'Update Profile';
include 'addplayerprofile.html.php';
exit();
}
if (isset($_GET['editform']))
{
include $_SERVER['DOCUMENT_ROOT'] . '/includes/db.inc.php';
// UPDATE MAIN PLAYER PROFILE DETAILS
try
{
$sql = "UPDATE player SET
name = :name,
age = :age,
position = :position,
height = :height,
weight = :weight,
satscore = :satscore,
gpa = :gpa,
email = :email,
filename = :filename,
mimetype = :mimetype,
filedata = :filedata
WHERE id = :id";
$s = $pdo->prepare($sql);
$s->bindValue(':id', $_POST['id']);
$s->bindValue(':name', $_POST['name']);
$s->bindValue(':age', $_POST['age']);
$s->bindValue(':position', $_POST['position']);
$s->bindValue(':height', $_POST['height']);
$s->bindValue(':weight', $_POST['weight']);
$s->bindValue(':satscore', $_POST['satscore']);
$s->bindValue(':gpa', $_POST['gpa']);
$s->bindValue(':email', $_POST['email']);
$s->bindValue(':filename', $uploadname);
$s->bindValue(':mimetype', $uploadtype);
$s->bindValue(':filedata', $uploaddata);
$s->execute();
}
catch (PDOException $e)
{
$error = 'Error editing player profile main details.' . $e->getMessage();
include 'error.html.php';
exit();
}
我以为我可以做这样的事情,但它不起作用:
if (isset($_FILES['upload']) && $_FILES['upload'] <> '')
{
$s->bindValue(':filename', $uploadname);
$s->bindValue(':mimetype', $uploadtype);
$s->bindValue(':filedata', $uploaddata);
}
else
{
$s->bindValue(':filename', $filename);
$s->bindValue(':mimetype', $mimetype);
$s->bindValue(':filedata', $filedata);
}
感谢所有帮助。

主要算法代码
if (isset($_POST['action']) and $_POST['action'] == 'Edit')
