导读基础cls_images.php: function upload_image(){}$_FILES 输出值：Array ( [group_thumb_url] => Array ( [name] => [type] => [tmp_name] => [error] => 4 [size] => 0 ) )

基础

cls_images.php: function upload_image(){}
$_FILES 输出值：Array ( [group_thumb_url] => Array ( [name] => [type] => [tmp_name] => [error] => 4 [size] => 0 ) )

实际操作
html代码：

<form method="post" action="group_buy.php?act=insert_update" name="theForm" onsubmit="return validate()" enctype="multipart/form-data">
<input type="file" name="group_thumb_url" size="35" />
</form>

注意：enctype="multipart/form-data" 不能丢掉
php代码

include_once(ROOT_PATH . '/includes/cls_image.php'); /*必须加上*/
$image = new cls_image($_CFG['bgcolor']);
$group_thumb_name = 'group_'.time().'.jpg'; /*图片名称命名*/
$upload_image= basename($image->upload_image($_FILES['group_thumb_url'],'group',$group_thumb_name));
if(!empty($upload_image)){ /*判断是否有新的文件上传*/
$group_thumb = $upload_image;
}
cls_images.php
function upload_image($upload, $dir = '', $img_name = '')
{
/* 没有指定目录默认为根目录images */
if (empty($dir))
{
/* 创建当月目录 */

{

}
}
/* 如果目标目录不存在，则创建它 */

{

}
}
