php - jQuery Validate MultIple File Upload -

i trying validate html file upload using jquery validate plugin,

my html form is,

<form id="formid" action="welcome/test_up" method="post" enctype="multipart/form-data"> <input type="file" name="myfile[]" id="myfile" multiple> <input type="submit" name="submit" id="submit" value="submit"/> 

and i'm using jquery validation plugin as,

$('#formid').validate({     rules: {         inputimage: { required: true, accept: "png|jpe?g|gif"  }     },     messages: { inputimage: "file must jpg, gif or png" } }); 

but unfortunately it's not working,

it's working if use name="myfile" not when use name="myfile[]"

any idea solve ?

try set rule in input tag become

<input type="file" name="myfile[]" id="myfile" accept="png|jpe?g|gif" multiple> 

so js only

$('#formid').validate();
