                    $this->City->create();
                        if ($this->City->saveAll($this->request->data)) {

                            $this->Session->setFlash(__('City has been added '));

//型号

    class city extends AppModel {
         public $validate = array(
           'city_name' => array(
            'nonEmpty' => array(
                'rule' => array('notEmpty'),

我想使用 saveAll 将多个城市数据一起保存。在添加更多按钮（java函数）的帮助下触发添加文本输入以添加多个城市的表单。 Cakephp saveAll 不工作。你能帮我做吗

Answer 1

我得到了我的解决方案。问题出在球场上。我正在动态更新表单的名称参数。

   <?php echo $this->Form->create('City');?>
        <fieldset>
        <?php 
        echo $this->Form->input('city_name', array('name' => 'City[0][city_name]'));
echo $this->Form->input('city_latitude', array('name' => 'City[0][city_latitude]'));
echo $this->Form->input('city_longitude', array('name' => 'City[0][city_longitude]'));
        ?>
        <div class="extra"></div>
        <div class="add_more_city" id="add_more_1"><button class="btn green">Add More</button></div>
        <?php echo $this->Form->submit('Save', array('class' => 'form-submit',  'title' => 'Click here to add the city')); ?>
    </fieldset>
<?php echo $this->Form->end(); ?>





<script>
    $(document).ready(function(){
        $('.add_more_city').click(function(e){
            e.preventDefault();
            var get_id=$('.add_more_city').attr('id');
            var split_id=get_id.split('_');
            var id = parseInt(split_id[2]);
            var id_update =id+1;
            $('.add_more_city').attr('id','add_more_'+id_update);
            $('.extra').before(' <div class="input text"><label for="CityCityName">City Name</label><input name="City['+id+'][city_name]" maxlength="100" type="text" id="CityCityName"/></div><div class="input number"><label for="CityCityLatitude">City Latitude</label><input name="City['+id+'][city_latitude]" step="any" type="number" id="CityCityLatitude"/></div><div class="input number"><label for="CityCityLongitude">City Longitude</label><input name="City['+id+'][city_longitude]" step="any" type="number" id="CityCityLongitude"/></div></div>');
        });
    });
    </script>

更改字段名称 -

echo $this->Form->input('city_name', array('name' => 'City[][city_name]'));
echo $this->Form->input('city_latitude', array('name' => 'City[][city_latitude]'));
echo $this->Form->input('city_longitude', array('name' => 'City[][city_longitude]'));
