不提交表格

标签: php jquery codeigniter

我的表单将在客户端进行验证,但我试图弄清楚为什么它在服务器端没有验证。我没有完整的PHP,但它甚至没有在我的控制台中提出POST请求,说它将表单提交给服务器。

jQuery的:

$(document).ready(function()
{

/*
* Validate the form when it is submitted
*/
var validateform = $("#newArticleForm").validate({
    invalidHandler: function(form, validator) {
        var errors = validator.numberOfInvalids();
        if (errors) {
            var message = errors == 1
            ? 'You missed 1 field. It has been highlighted.'
            : 'You missed ' + errors + ' fields. They have been highlighted.';
            $('.box .content').removeAlertBoxes();
            $('.box .content').alertBox(message, {type: 'warning', icon: true, noMargin: false});
            $('.box .content .alert').css({
                width: '100%',
                margin: '0',
                borderLeft: 'none',
                borderRight: 'none',
                borderRadius: 0
            });
        } else {
            $('.box .content').removeAlertBoxes();
        }
    },
    showErrors : function(errorMap, errorList) {
        this.defaultShowErrors();
        var self = this;
        $.each(errorList, function() {
            var $input = $(this.element);
            var $label = $input.parent().find('label.error').hide();
            $label.addClass('red');
            $label.css('width', '');
            $input.trigger('labeled');
            $label.fadeIn();
        });
    },
    submitHandler: function(form) {
        var dataString = $('#newArticleForm').serialize();
        $.ajax({
            type: 'POST',
            url: '/kowmanager/dashboard/articleSubmit',
            data: dataString,
            dataType: 'json',
            success:  function(data) {
                if (data.error) {
                    $('.box .content').removeAlertBoxes();
                    $('.box .content').alertBox(data.message, {type: 'warning', icon: true, noMargin: false});
                    $('.box .content .alert').css({
                        width: '',
                        margin: '0',
                        borderLeft: 'none',
                        borderRight: 'none',
                        borderRadius: 0
                    });
                }
                else
                {
                    $('.box .content').removeAlertBoxes();
                    $('.box .content').alertBox(data.message, {type: 'success', icon: true, noMargin: false});
                    $('.box .content .alert').css({
                        width: '',
                        margin: '0',
                        borderLeft: 'none',
                        borderRight: 'none',
                        borderRadius: 0
                    }); 
                    $(':input','#newArticleForm')
                    .not(':submit, :button, :hidden, :reset')
                    .val('');  
                }
            }
        });
    }
});

});

控制器:

function articleSubmit()
{
    $outputArray = array('error' => 'yes', 'message' => 'unproccessed');
    $outputMsg = '';
    // Sets validation rules for the login form
    $this->form_validation->set_rules('title', 'Title',
        'trim|required|xss_clean|alpha_numeric');
    $this->form_validation->set_rules('category', 'Category',
        'integer');
    $this->form_validation->set_rules('isSticky', 'Is Sticky',
        'integer');
    $this->form_validation->set_rules('comments', 'Allow Comments',
        'integer');    

    // Checks to see if login form was submitted properly
    if (!$this->form_validation->run())
    {
        $outputArray['message'] =
            'There was a problem submitting the form! Please refresh the window and try again!';
    }
    else
    {

    }
}

我还有其他使用此jquery的表单,但想知道是否有人有任何其他想法?

1 个答案:

答案 0 :(得分:0)

我知道这个问题的答案......它让我疯了,所以我很乐意帮助你解决这个问题:))

Codeigniter以非常特殊的方式使用POST请求。如果你这样做但是使用GET请求你会发现它工作正常......那么发生了什么?

Codeigniter有一个crsf令牌,以确保您以安全的方式发布数据。 因此,请确保将此crsf值与其余数据一起发送。

我会举个例子,这是我的POST ajax + codeigniter的样子:

$.ajax({
        type: 'POST',
        dataType: 'HTML',
        data: {
            somevalue : somevalue,
            csrf_test_name  : $.cookie('csrf_cookie_name')
        },

...

如您所见,您的crsf值存储在cookie中。我使用jquery插件cookie帮助器,但使用任何其他插件感觉很难。

但是,请记住,在发出POST请求时,codeigniter始终需要名称“csrf_test_name”

度过美好的一天!
