Question

控制器功能代码：

$surveydata = $this->getsurveydatabasedonId($SurveyId);
$this->load->view('editsurvey', array('surveydata' => $surveydata));

查看代码：

   <h1 class="page-header">Edit Survey</h1>
                <?php
                $att = array('id' => 'editsurvey_form', 'role' => 'ajax-form');
                echo form_open('welcome/editsurvey', $att);
                ?>
                <div class="span5 offset1" id="form_div">
                    <?php echo validation_errors('<div class="alert alert-danger reg_error">', '</div>'); ?>
                    <div class="form-group control-group warning">
                        <input name="SurveyId" style="display:none" type="text" class="form-control" data-validation-required-message="Please enter a Survey Id" id="SurveyId" required placeholder="Please enter the Survey Id" value="<?php echo set_value('SurveyId', $surveydata->SurveyId); ?>">
                        <label for="SurveyTitle">Survey Title</label>
                        <input name="SurveyTitle" type="text" class="form-control" data-validation-required-message="Please enter a Survey Title" id="SurveyTitle" required placeholder="Please enter the Survey Title" value="<?php echo set_value('SurveyTitle', $surveydata->SurveyTitle); ?>">
                        <p class="help-block"></p>
                    </div>
                    <div class="form-group control-group warning">
                        <label for="SurveyIntroduction">Survey introduction</label>
                        <textarea name="SurveyIntro" type="text" class="form-control" id="SurveyIntro" placeholder="Enter the Survey Introduction"><?php echo set_value('SurveyIntro', $surveydata->SurveyIntro); ?></textarea>
                    </div>

                    <button type="submit" class="btn btn-large btn-warning">Edit Survey</button>
                </div>
                </form>

我收到以下错误：

 A PHP Error was encountered

Severity: Notice

Message: Trying to get property of non-object

Filename: views/editsurvey.php

Line Number: 11

我正在通过阵列，但它不起作用，有人可以帮我吗？

Answer 1

应该是$surveydata[0]['SurveyId']，而不是$surveydata->SurveyId

SurveyTitle也是如此它应该是$surveydata[0]['SurveyTitle']，而不是$surveydata->SurveyTitle

Answer 2

请确认，

您的$surveydata。

中有数据

如果您通过

获取结果

$resultSet->result()或$resultSet->row()，然后使用$surveydata->SurveyTitle

如果您通过以下方式获取结果：

$resultSet->result_array()或$resultSet->row_array()，然后使用$surveydata['SurveyTitle]

另外，请务必核对$surveydata

的计数
