HomeBackend DevelopmentPHP TutorialPHP CKEditor 上传图片实现代码_php技巧

我花了一个下午的时间,自己用PHP脚本写了一个处理上传文件的脚本代码,没有做更多的安全处理,希望对大家有用。
首先,在你的config.js文件里添加如下代码:

复制代码 代码如下:

CKEDITOR.editorConfig = function( config )
{
config.filebrowserImageUploadUrl = './upload.php?type=img';
config.filebrowserFlashUploadUrl = './upload.php?type=flash';
};

以上的配置是上传要处理到的文件的地址,你可以根据自己情况进行修改。upload.php文件如下:
复制代码 代码如下:

/*
CKEditor_upload.php
monkee
2009-11-15 16:47
*/
$config=array();
$config['type']=array("flash","img"); //上传允许type值
$config['img']=array("jpg","bmp","gif"); //img允许后缀
$config['flash']=array("flv","swf"); //flash允许后缀
$config['flash_size']=200; //上传flash大小上限 单位:KB
$config['img_size']=500; //上传img大小上限 单位:KB
$config['message']="上传成功"; //上传成功后显示的消息,若为空则不显示
$config['name']=mktime(); //上传后的文件命名规则 这里以unix时间戳来命名
$config['flash_dir']="/ckeditor/upload/flash"; //上传flash文件地址 采用绝对地址 方便upload.php文件放在站内的任何位置 后面不加"/"
$config['img_dir']="/ckeditor/upload/img"; //上传img文件地址 采用绝对地址 采用绝对地址 方便upload.php文件放在站内的任何位置 后面不加"/"
$config['site_url']=""; //网站的网址 这与图片上传后的地址有关 最后不加"/" 可留空
//文件上传
uploadfile();
function uploadfile()
{
global $config;
//判断是否是非法调用
if(empty($_GET['CKEditorFuncNum']))
mkhtml(1,"","错误的功能调用请求");
$fn=$_GET['CKEditorFuncNum'];
if(!in_array($_GET['type'],$config['type']))
mkhtml(1,"","错误的文件调用请求");
$type=$_GET['type'];
if(is_uploaded_file($_FILES['upload']['tmp_name']))
{
//判断上传文件是否允许
$filearr=pathinfo($_FILES['upload']['name']);
$filetype=$filearr["extension"];
if(!in_array($filetype,$config[$type]))
mkhtml($fn,"","错误的文件类型!");
//判断文件大小是否符合要求
if($_FILES['upload']['size']>$config[$type."_size"]*1024)
mkhtml($fn,"","上传的文件不能超过".$config[$type."_size"]."KB!");
//$filearr=explode(".",$_FILES['upload']['name']);
//$filetype=$filearr[count($filearr)-1];
$file_abso=$config[$type."_dir"]."/".$config['name'].".".$filetype;
$file_host=$_SERVER['DOCUMENT_ROOT'].$file_abso;
if(move_uploaded_file($_FILES['upload']['tmp_name'],$file_host))
{
mkhtml($fn,$config['site_url'].$file_abso,$config['message']);
}
else
{
mkhtml($fn,"","文件上传失败,请检查上传目录设置和目录读写权限");
}
}
}
//输出js调用
function mkhtml($fn,$fileurl,$message)
{
$str='';
exit($str);
}
?>

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.
