Question

我正在使用Βootstrap和jQuery File Upload Plugin作为提交表单，当我想提交第二张图片时，当我在表单中添加第二个元素时，我遇到了问题。

注意： Form按原样启动jQuery File Upload插件的UploadHandler，不进行任何编辑。

HTML

<form id="edit-form" method="post" action="save.php" class="form-horizontal" enctype="multipart/form-data">
    <div class="col-sm-12 input-div-body">

        <? if ($saveddata->num_rows !== 0) { ?>
            <? foreach ($saveddata as $data) { ?>
                <!-- form inputs -->
                <div id="form-inputs" class="form-inputs">
                    <div class="form-group">
                        <label class="col-sm-2 control-label">Όνομα:</label>

    $(function () {
        'use strict';
        // Change this to the location of your server-side upload handler:
        var url = 'server/php/';
        $('#fileupload').fileupload({

JAVASCRIPT

/* Save form post functions */
    $('#edit-form').submit(function (event) {
        event.preventDefault();
        $.ajax({
            data: $(this).serialize(),
            type: $(this).attr('method'),
            url: $(this).attr('action'),
            success: function (response) {
                $("#save-alert").removeAttr('hidden');
                if (response == 'success') {
                    $("#save-alert").removeClass('alert-danger')
                        .addClass('alert-success')
                        .html('Αποθήκευση επιτυχής')
                        .scrollTop(300);
                    location.reload(true);
                } else {
                    $("#save-alert").html(response).scrollTop(300);
                }
            }
        });
        return false;
    });

当用户单击“添加更多”按钮时，将启动以下js函数，该函数会添加表单元素的副本：

$('#btn-add-more').click(function () {
    $(".input-div-body").append('<!-- form inputs --><div id="form-inputs" class="form-inputs"><div class="form-group"><label class="col-sm-2 control-label">Όνομα:</label><div class="col-sm-8"><input type="text" class="form-control" name="name[]"></div></div><div class="form-group"><label class="col-sm-2 control-label">Μέγεθος:</label><div class="col-sm-8"><input type="text" class="form-control" name="size[]"></div></div><div class="form-group"><label class="col-sm-2 control-label">Πέλμα:</label><div class="col-sm-8"><input type="text" class="form-control" name="tread[]"></div></div><div class="form-group"><label class="col-sm-2 control-label">Διαθέσιμο:</label><div class="col-sm-8"><input type="text" class="form-control" name="availability[]"></div></div><div class="form-group"><label class="col-sm-2 control-label">Εικόνα:</label><div class="col-sm-8"><!-- The fileinput-button span is used to style the file input field as button --><span class="btn btn-default fileinput-button"><i class="glyphicon glyphicon-picture"></i><span id="files"> Προσθήκη Εικόνας...</span><!-- The file input field used as target for the file upload widget --><input id="fileupload" type="file" name="files[]" data-url="server/php/" multiple></span><!-- The global progress bar --><div id="progress" class="progress hidden"><div class="progress-bar progress-bar-info progress-bar-striped"></div></div><input type="hidden" name="id[]"><input id=image type="hidden" name="image[]"></div></div></div><!-- /form-inputs --><hr>');
});

我没有收到任何error_log或控制台错误。有什么建议吗？

提前谢谢

Answer 1

我认为在添加表单元素的副本后，您必须再次运行文件上载脚本

$('#fileupload').fileupload({ ... })

我还建议用类fileupload替换id fileupload，并用类运行脚本，例如

$('.fileupload').fileupload({ ... })

无法以相同的格式上传第二张图片
