Thinkphp3.2.3 多图上传，同类型只能上传一张问题

Thinkphp3.2.3 多图上传，同类型只能上传一张问题，
例如一次性上传多张 .jpg 文件，只能上传最后一张，
问题在于，同名，只保存一张，找了很多方法，问题就在于 saveName 上

在 App->Common->Common->function.php 下加入

function guid()
{
    if (function_exists('com_create_guid')) {
        return com_create_guid();
    } else {
        mt_srand((double) microtime() * 10000);
        $charid = strtoupper(md5(uniqid(rand(), true)));
        $hyphen = chr(45);
        $uuid   = chr(123)
        . substr($charid, 0, 8) . $hyphen
        . substr($charid, 8, 4) . $hyphen
        . substr($charid, 12, 4) . $hyphen
        . substr($charid, 16, 4) . $hyphen
        . substr($charid, 20, 12)
        . chr(125);
        return $uuid;
    }
}

再在 upload方法中 saveName = array(‘guid’, ‘’);
完整代码如下

public function upload()
{
    $upload           = new \Think\Upload();
    $upload->maxSize  = 0;
    $upload->exts     = array('jpg', 'gif', 'png', 'jpeg');
    $upload->rootPath = './Public/upload/';
    $upload->savePath = 'thumb/';
    // $now              = $_SERVER['REQUEST_TIME'];
    $upload->saveName = array('guid', '');

    $info = $upload->upload();
    if (!$info) {
        $this->error($upload->getError());
    } else {
        $this->success('上传成功!');
    }
}

前端代码

上面出来的图片路径是 {5141258E-8008-E064-26EB-4EC6642B71AB} 这样的，我们优化一下，把左右的 大括号去掉，并把中划线改成下划线。

if (function_exists('com_create_guid')) {
    return com_create_guid();
} else {
    mt_srand((double) microtime() * 10000);
    $charid = strtoupper(md5(uniqid(rand(), true)));

    $hyphen = chr(95); //下划线

    $uuid   = substr($charid, 0, 8) . $hyphen
    . substr($charid, 8, 4) . $hyphen
    . substr($charid, 12, 4) . $hyphen
    . substr($charid, 16, 4) . $hyphen
    . substr($charid, 20, 12);

    return $uuid;
}

这样就变成 C4D414B3_D751_173B_BCD9_F8C8CE95C5F5.jpg
