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
<form enctype="multipart/form-data" action="__URL__/upload" method="post"> <input type="file" name="myFile[]" multiple /> <input type="submit" value="提交"></form>
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
