php上传图片代码
php单个页面实现上传图片代码,点击按钮现实php上传图片代码
调用代码如下:
<input type="button" value ="上传图片" onclick="window.open('up_img.php?textname=返回的文本框名&formname=form名称','newwindow','height=20,width=240,top=200,left=300,toolbar=no,menubar=no,scrollbars=no,resizable=no,location=no,status=no')">
下面是up_img.php
<?php
session_start();
error_reporting(E_ALL^E_NOTICE);//去除变量为空时的错误
require_once('../date_conn/user_conn.php');
require_once('../function/function.php');
check_login("c","company_login.php");
$uptypes=array('image/jpg', //上传文件类型列表
'image/jpeg',
'image/png',
'image/pjpeg',
'image/gif',
'image/bmp',
'image/x-png');
$max_file_size=204800; //上传文件大小限制, 单位BYTE
$destination_folder="C_img/".$_SESSION["c_id"]."/"; //上传文件路径
$watermark=1; //是否附加水印(1为加水印,其他为不加水印);
$watertype=1; //水印类型(1为文字,2为图片)
$waterposition=1; //水印位置(1为左下角,2为右下角,3为左上角,4为右上角,5为居中);
$waterstring=""; //水印字符串
$waterimg=""; //水印图片
$imgpreview=0; //是否生成预览图(1为生成,其他为不生成);
$imgsmallsize=100; //缩略图大小定义
?>
