控制器函数代码：
$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); ?>">

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
正在传递数组，但它不起作用，有人可以帮我吗？
请确保，
您的$surveydata中有数据。
如果您通过以下方式获取结果
$resultSet->result()或$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$surveydata['SurveyTitle]
另外，请务必检查$surveydata计数
它应该是$surveydata[0]['SurveyId']，而不是$surveydata->SurveyId
与调查标题相同它应该是$surveydata[0]['SurveyTitle']，而不是$surveydata->SurveyTitle
