部分回答question
我有PHP代码,它将一个裁剪的图像上传到3个不同的宽度和高度
并使用MD5随机重命名图像。
<?php
function uploadImageFile() { // Note: GD library is required for this function
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$iJpgQuality = 100;
if ($_FILES) {
// if no errors and size less than 250kb
if (! $_FILES['image_file']['error'] && $_FILES['image_file']['size'] < 250 * 1024) {
if (is_uploaded_file($_FILES['image_file']['tmp_name'])) {
if (!is_dir('avatar')) {
mkdir('avatar');
}
// new unique filename
$sTempFileName = 'avatar/' . md5(time().rand());
// move uploaded file into cache folder
move_uploaded_file($_FILES['image_file']['tmp_name'], $sTempFileName);
// change file permission to 644
@chmod($sTempFileName, 0644);
$sResultFileName = copyImageFile('avatar', $sTempFileName, 200, 200, $iJpgQuality);
if ($sResultFileName) {
copyImageFile('avatar1', $sTempFileName, 500, 500);
copyImageFile('avatar2', $sTempFileName, 700, 700);
@unlink($sTempFileName);
return $sResultFileName;
}
}
}
}
}
return false;
}
function copyImageFile($dirName, $originImageName, $iWidth, $iHeight, $iJpgQuality = 90) {
if (file_exists($originImageName) && filesize($originImageName) > 0) {
$aSize = getimagesize($originImageName); // try to obtain image info
if (!$aSize) {
@unlink($originImageName);
return;
}
// check for image type
switch($aSize[2]) {
case IMAGETYPE_JPEG:
$sExt = '.jpg';
$vImg = @imagecreatefromjpeg($originImageName);
break;
/*case IMAGETYPE_GIF:
$sExt = '.gif';
// create a new image from file
$vImg = @imagecreatefromgif($sTempFileName);
break;*/
case IMAGETYPE_PNG:
$sExt = '.png';
$vImg = @imagecreatefrompng($originImageName);
break;
default:
@unlink($originImageName);
return;
}
// create a new true color image
$vDstImg = @imagecreatetruecolor( $iWidth, $iHeight );
// copy and resize part of an image with resampling
imagecopyresampled($vDstImg, $vImg, 0, 0, (int)$_POST['x1'], (int)$_POST['y1'], $iWidth, $iHeight, (int)$_POST['w'], (int)$_POST['h']);
// define a result image filename
if (!is_dir($dirName)) {
mkdir($dirName);
}
$newImageName = $dirName . DIRECTORY_SEPARATOR . md5(time().rand()) . $sExt;
// output image to file
imagejpeg($vDstImg, $newImageName, $iJpgQuality);
//@unlink($sTempFileName);
return $newImageName;
}
return false;
}
$sImage = uploadImageFile();
echo '<img src="'.$sImage.'" />';
?>
我的问题
我想在ara MySQL
数据库
Avatar
column =上传到头像目录的图片的网址Avatar1
column =上传到avatar1目录的图片的网址Avatar2
column =上传到avatar2目录的图片的网址数据库名称:ara
数据库用户:root
数据库密码:
数据库地址:127.0.0.1
表名:个人资料
列名:avatar,avatar1和avatar2
答案 0 :(得分:2)
copyImageFile('avatar1', $sTempFileName, 500, 500);
copyImageFile('avatar2', $sTempFileName, 700, 700);
在
之后替换此代码 include('connect/mysql.php');
$avatar1=copyImageFile('avatar1', $sTempFileName, 500, 500);
$avatar2=copyImageFile('avatar2', $sTempFileName, 700, 700);
$user_name = mysqli_real_escape_string($con, $_SESSION['UserName']);
mysqli_query($con,"UPDATE profiles SET AvatarImage='".$sResultFileName."',AvatarImageBig='".$avatar1."',AvatarImageSmall='".$avatar2."' WHERE UserName = '$user_name'");
mysqli_close($con);
答案 1 :(得分:0)
感谢@Banjamin和@Qaisar
您在函数中使用$ con
uploadImageFile($user_name),
所以你应该将变量
$con
传递给这个函数 喜欢
uploadImageFile($user_name, $con)
当然你必须改变 你的职能接受了论点。
