PHP Ajax $ _POST随机为空

Question

I encounter a strange occurrence with posting information through Ajax. The script is nothing complex

$.post('somefile.php?arg1=somearg&ar2=somearg', {
   somearg: variable,
   ...
}, function(response){});

The weird part is when clicking the save button for 1st and 2nd time, the server throws and error that $_POST is empty. But when clicking for 3rd and 4th time, it works, without modifying anything on the page.

I know about the php config post_max_size or upload_max_size, it's not a problem and the data is very few.

Please help.

Maybe just try:

    jQuery('#loader').show();
    jQuery.ajax({
        type: "POST",
        url: yourURL,
        data: {somearg: variable, id: variable2}
    }).done(function( data ) {
        console.log(data);
        jQuery('#loader').hide();
    });
