what code should be in upload.php for jquery swfupload? -

-

i started using jquery swfupload plugin , have working besides upload part... don't know put in upload.php file.

i error: alert: {"name":"","type":"","size":""}; file: mayday-parade.png

upload.php had code:

$file = $_files['file']; echo '{"name":"'.$file['name'].'","type":"'.$file['type'].'","size":"'.$file['size'].'"}';

obviously doesn't work added following: 

if (file_exists($_server['document_root'].'/band_photos/' . $_files["file"]["name"])) {     echo 'file exists'; } else {     $uploaddir = 'uploads/';     $uploadfile = $uploaddir . basename($_files['file']['name']);     if(move_uploaded_file($_files["file"]["tmp_name"], $uploadfile)) {                       echo 'success'; } else {     echo 'error'; }    }

i can't seem find out i'm doing wrong. can help?

have changed the file_post_name in swfupload's settings "file"?

if not, $_files['file'] not return anything, because default-name filedata , use $_files['filedata'] instead.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
