Php Blueimp jQuery文件上载和codeigniter上载，并重命名和调整图像大小

我已经搜索和尝试了很多很多天，我正在使用

对于使用codeigniter上传多个文件，我对使用它的某些方面有疑问：

如何使用serial like 15_1.jpg重命名上传的文件/ 15_2.jpg/15_3.jpg 如何使用同一表格提交两次首次提交 上传，然后第二次提交，以便向数据库插入一些输入。 上传前如何调整图像大小 1用于重命名 而不是

move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $_FILES["file"]["name"]);

这样做,

$temp = explode(".", $_FILES["file"]["name"]);
$newfilename = round(microtime(true)) . '.' . end($temp);
move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $newfilename);

将根据当前时间生成一个随机数，并从最初上载的文件中附加扩展名

2使用同一表单上传和插入时，需要两个按钮

$(function () {
    $('#fileupload').fileupload({
        dataType: 'json',
        add: function (e, data) {
            data.context = $('<button/>').text('Upload')
                .appendTo(document.body)
                .click(function () {
                    data.context = $('<p/>').text('Uploading...').replaceAll($(this));
                    data.submit();
                });
        },
        done: function (e, data) {
            data.context.text('Upload finished.');
        }
    });
});

请每个问题保留一个问题，不要问宽泛的问题。@Alex好吧，他们与同一主题相关，我不能在另一个问题中分开，这很好地表明你的问题太宽泛了。尽管它们可能是相关的，但这并不意味着你不能一步一步地尝试，并在过程中提出问题。
