请问一下php的pdo如何将图片路径和内容一起上传？谢谢了！
思路，大概思路是这样的。一般都是将图片上传到服务器自己设定的一个目录下，同时将图片名称等信息插入数据表，数据库存图片名称路径就好了。不要将图片的二进制信息存入数据库，那样很浪费数据库空间非常不好(本人曾经这样看教程做过)。至于你说的怎么在另一个php文件引用，要么查询数据库取到图片名称路径。具体上传代码可以参考:HTML代码form enctype="multipart/form-data" action="__URL__" method="POST" input type="hidden" name="MAX_FILE_SIZE" value="30000" / Send this file: input name="userfile" type="file" / input type="submit" value="Send File" //formphp代码?php print_r($_FILES['userfile']);//打印看看结果，然后查看手册$_FILES研究下吧?
input file用了multiple属性,而且选择了多张图片,PHP该怎么上传？
其实就那两个函数\x0d\x0ais_uploaded_file()和move_uploaded_file()\x0d\x0a是循环上传的。你打印下$_FILES这个超全局数组就明白了。下面我的测试代码上传图片的：\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a \x0d\x0a无标题\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a\x0d\x0a
