我希望将变量格式化为价格格式,如果它是例如$ 90,则忽略它已经做过的小数.但如果价值是44.5美元,那么我想将其格式化为44.50美元.我可以在php而不是javascript中做到这一点.

PHP示例:

number_format($price, !($price == (int)$price) * 2);

我要格式化的代码:

$(showdiv+' .calc_price span').html(sum_price);

我试图在谷歌地图api上设置一些路标,但得到以下错误.我知道它与设置一个对象有关,但我似乎无法正确对待它.我也找不到任何确切的文章.

Error: Error in property <waypoints>: (Invalid value: Ballybricken, Waterford, Ireland,The Glen, Waterford (Error in element at position 0: (Unknown property <0>)))

我的代码

var waypts = ["Ballybricken, Waterford, Ireland", "The Glen, Waterford"];
drawPolyline('Waterford Regional Hospital', 'Hillview, Waterford, Ireland', waypts);


function drawPolyline(source,destination,waypoints){
        // show route between the points
        directionsService = new google.maps.DirectionsService();
        directionsDisplay = new google.maps.DirectionsRenderer(
        {
            suppressMarkers: true,
            suppressInfoWindows: true,
            polylineOptions: { strokeColor: '#000000', strokeOpacity: 0.5 } 
        });
        directionsDisplay.setMap(map);
        var request = {
            origin:source, 
            destination:destination,
            waypoints:waypoints,
            travelMode: google.maps.DirectionsTravelMode.DRIVING
        };
        directionsService.route(request, …

我有一个Users模型,它与Employees模型有一个hasOne关系.当我保存用户时,我还使用user_id在Employees表中添加记录.这很好用.

Employee可以通过CoursesEmployees表与belongsToMany课程相关联.当我只保存员工时,这可以保存.

我的问题是我要保存全部3个,但课程没有得到保存.

保存用户 - >使用新的user_id保存员工 - >在courses_employees中使用employee_id保存为新员工选择的课程

EmployeesTable.php

public function initialize(array $config)
{
    $this->table('employees');
    $this->displayField('name');
    $this->primaryKey('id');
    $this->addBehavior('Timestamp');
    $this->belongsTo('Users', [
        'foreignKey' => 'user_id',

    ]);
    $this->belongsTo('Hotels', [
        'foreignKey' => 'hotel_id',
        'joinType' => 'INNER'
    ]);
    $this->belongsToMany('Courses', [
        'foreignKey' => 'employee_id',
        'targetForeignKey' => 'course_id',
        'joinTable' => 'courses_employees'
    ]);
}

用户add.ctp:

<?= $this->Form->create($user) ?>
<fieldset>
    <legend><?= __('Add User') ?></legend>
    <?php
        echo $this->Form->input('role_id', ['options' => $roles, 'empty' => true]);
        echo $this->Form->input('email');
        echo $this->Form->input('active');
        echo $this->Form->input('activation_key');
        echo $this->Form->input('password');
        echo $this->Form->input('employee.name');
        echo $this->Form->input('employee.email');
        echo $this->Form->input('employee.surname');
        echo $this->Form->input('employee.employee_num'); …

我有一个图片上传，将文件名添加到名为附件的表中。如果该ID已经存在，那么我希望它进行更新，如果不存在，则创建一个新记录。目前它创建了一条新记录，因此我有一个ID的多个记录。ID来自称为Addon的表。

我不确定如何在cakephp中执行此操作。

    if (!empty($this->data)) {
        $this->layout = null;
        //if(empty($this->data['AddOn']['id'])){unset($this->data['AddOn']);}

        // restructure data for uploader plugin // NEED TO GET RID OF THIS ? MOVE IT
        $tmp_file = $this->data['Attachment'][0]['file'];
        $tmp_file['extension'] =  array_reverse(explode('.', $tmp_file['name']));
        $tmp_file['extension'] = $tmp_file['extension'][0];
        $tmp_file['title'] = strtolower(substr($tmp_file['name'],0,(0-strlen('.'.$tmp_file['extension']))));
        $this->data['Attachment'][0]['alternative'] = ucwords(str_replace('_',' ', $tmp_file['title']));

        $previous = $this->AddOn->Attachment->find('first', array('conditions'=> array('model'=>'AddOn', 'foreign_key'=>$id)));
        if( !empty( $previous ) ) {
            $this->AddOn->Attachment->id = $previous[ 'Attachment' ][ 'id' ];
        }

        if ($this->AddOn->save($this->data, array('validate' => 'first'))) {    

            $id = $this->AddOn->Attachment->getLastInsertID();

            $att = $this->AddOn->Attachment->query("SELECT * from attachments WHERE id …

我试图添加到一个变量并在循环结束时获取总价，并将其添加到 span 标签中的值并更新它。我不确定如何使用 jquery，我通常使用 php 来做。这是我尝试过的，但我什么也没得到。

$.each(data, function(key, obj) {
    items.push('<li id="' + obj.id + '">' + obj.title + '€' + obj.price + '</li>');
    totalprice += obj.price
});

$("#addonPrice").html($("#addonPrice").text() + totalprice);

我试图将一些json传递给cakePHP 2.5中的控制器并再次返回它,以确保它完全正常.

但是我没有回复内容.只有200个成功.从阅读文档我的印象是,如果我传递一些json,那么responseHandler将返回json作为响应.

不确定我错过了什么.

数据被传递

var neworderSer = $(this).sortable("serialize");

这使

item[]=4&item[]=3&item[]=6&item[]=5&item[]=7 

appController.php

public $components = array(
    'DebugKit.Toolbar', 
    'Search.Prg', 
    'Session', 
    'Auth',
    'Session',
    'RequestHandler'
);

index.ctp

    $.ajax({
        url: "/btstadmin/pages/reorder",
        type: "post",
        dataType:"json",
        data: neworderSer,
        success: function(feedback) {
            notify('Reordered pages');
        },
        error: function(e) {
            notify('Reordered pages failed', {
                status: 'error'
            });
        }
    });

PagesController.php

public function reorder() {

    $this->request->onlyAllow('ajax');
    $data = $this->request->data;
    $this->autoRender = false;
    $this->set('_serialize', 'data');

}

更新:我现在已将以下内容添加到routes.php中

    Router::parseExtensions('json', 'xml');

我已将控制器更新为

    $data = $this->request->data;

    $this->set("status", "OK");
    $this->set("message", "You are good");
    $this->set("content", $data); …

我将我的应用程序覆盖到cakephp 3.0，并且在查找方法中找不到使用邻居的替代方法时遇到了麻烦。

我需要在关联的表中找到下一条记录，而邻居是完成记录的好方法。

//Open courses
$options = [
    'conditions' => ['Employees.user_id' => 1, 'CoursesEmployees.completed' => false],
    'limit' => 3,
    'contain' => 'Employees'
];
$recentOpen = $this->CoursesEmployees->find('all', $options)->toArray();

// get next module for each open course
foreach ($recentOpen as $key => &$value) {
    $currentModule = $value['CourseModule']['id'];
    $neighbors = $this->CoursesEmployees->CourseModules->find(
        'neighbors',
        ['field' => 'id', 'value' => $currentModule]
    );
    $value['CourseModule']['next_module'] = $neighbors['next']['CourseModule']['name'];
};

我发现的代码的另一个问题是，$this->CoursesEmployees->find('all', $options)->toArray();似乎返回了一个复杂数组，其中cakephp用于查询表的所有内容，而不是像cakephp 2那样的实际结果。我在->toArray()3.0中推荐添加

我有两个包裹在div中的段落.我想让第一段文本稍大一些,但使用:first-child不能像我调用它一样工作.不知道出了什么问题.

        <div id="main-content">
            <h2 class="title">

我已经搜索了如何获得一个名为积分的字段的高低.我只需要一个总数,但我能得到的最好的是Points表中的记录列表以及来自成员的相关记录.

    $totalPoints = $this->Member->Point->find('all', array(
               array('fields' => array('sum(Point.points)   AS Point.ctotal'))));

我希望将变量插入对象键结构中，但我只获取变量名称而不是变量值。

var winnerId = 10;
var loserId = 11;        

newMessage.setMessageData({
  winnerId : {
    "status" : "win",
    "choice" : playerData[winnerId]["currentChoice"],
    "newScore" : playerData[winnerId]["score"]
  },
  loserId : {
    "status" : "lost",
    "choice" : playerData[loserId]["currentChoice"],
    "newScore" : playerData[loserId]["score"]
  }           
});
