消息：未定义的变量：键

Question

编辑记录时收到以下错误消息：Message: Undefined variable: keys

这是我的视图，带有操作按钮propertie_key_list；

<?php foreach ($ci_broker_propertie_key as $keys) : ?>
            <tr>
                <!--<th><?= $keys['propertie_key_id'] ?></th>-->
                <th><?= $keys['chave_descricao'] ?></th>
                <th><?= $keys['chave_codigo'] ?></th>
                <th><?= $keys['chave_status'] ?></th>
                <th>
                  <div><a title="Delete" class="delete btn btn-sm btn-danger pull-right '.$disabled.'" data-href="<?php echo base_url('user/propertie_key/del/'.$keys['propertie_key_id']);?>" data-toggle="modal" data-target="#confirm-delete"> <i class="material-icons">delete</i></a></div> 
                  <div><a title="Edit" class="update btn btn-sm btn-primary pull-right" href="<?php echo base_url('user/propertie_key/edit/'.$keys['propertie_key_id']);?>"> <i class="material-icons">edit</i></a></div> 
                  <div><a title="View" class="view btn btn-sm btn-info pull-right" href="<?php echo base_url('user/propertie_key/edit/'.$keys['propertie_key_id']);?>"> <i class="material-icons">visibility</i></a></div>
                </th>
            </tr>
      <?php endforeach ?>

这是我的观点propertie_key_edit出现错误的地方

<?php echo form_open(base_url('user/propertie_key/edit/'.$keys['propertie_key_id']), 'class="form-horizontal"')?>
      <div class="row clearfix">
            <div class="col-lg-2 col-md-2 col-sm-4 col-xs-5 form-control-label">
                <label for="chave_descricao">Nome</label>
            </div>
            <div class="col-lg-8 col-md-10 col-sm-8 col-xs-7">
                <div class="form-group">
                    <div class="form-line">
                        <input type="text" id="chave_descricao" name="chave_descricao" value="<?= $keys['chave_descricao']; ?>" class="form-control">
                    </div>
                </div>
            </div>
        </div>

Answer 1

第一步是从]中更改按钮url中的url>

 base_url('user/propertie_key/edit/'.$keys['propertie_key_id']);
到

base_url('user/propertie_key/edit/&k='.$keys['propertie_key_id']);
（注意＆k =）然后，当您调用fopen函数时，请像这样使用GET参数

form_open(base_url('user/propertie_key/edit/'.$_GET['k']);
