Undefined property: stdClass alamat
在我的观点中，
$ this-＆gt; data ['prodi'] = $ this-＆gt; mprodi-＆gt; get_all_prodi（）;
在我的控制器视图中，我收到此错误。但是当我没有接受我的选择时prodi没有显示。
这是我的观点：
<div class="field">
<label>Piih Prodi</label>
<input type="hidden" name="nama_prodi" value="<?php echo $data->nama_prodi;?>"><?php echo form_error('nama_prodi', '<div class="ui red pointing label">', '</div>'); ?>
<select name="prodi" id="select_prodi">
<?php foreach ($prodi as $prodi_data) :?>
<?php echo '<option value="'.$prodi_data->id_prodi.'">'.$prodi_data->nama_prodi.'</option>'; ?>
<?php endforeach; ?>
</select>
</div>
<div class="field">
<label>Fakultas</label>
<div class="ui small left icon input">
<input type="text" disabled="disabled" id="fakultas" class="fakultas" placeholder="fakultas" name="nama_fakultas">
<i class="text file outline icon"></i>
</div>
</div>
<div class="field">
<label>Alamat</label>
<textarea placeholder="text" name="alamat">
<?php echo $data->alamat;?>
</textarea><?php echo form_error('alamat', '<div class="ui red pointing label">', '</div>'); ?>
</div>

请告诉我该怎么做。
谢谢

这是因为您在打印该变量之前已经结束了foreach循环 试试这个
<label>Piih Prodi</label>
<div>
<input type="hidden" name="nama_prodi" value="<?php echo $data->nama_prodi;?>"><?php echo form_error('nama_prodi', '<div class="ui red pointing label">', '</div>'); ?>
<select name="prodi" id="select_prodi">
<?php foreach ($prodi as $data) :?>
<?php echo '<option value="'.$data->id_prodi.'">'.$data->nama_prodi.'</option>'; ?>
// Other code ..
<div class="field">
<label>Alamat</label>
<textarea placeholder="text" name="alamat">
<?php echo $data->alamat;?>
<?php endforeach; ?>
</textarea><?php echo form_error('alamat', '<div class="ui red pointing label">', '</div>'); ?>
</div>

这只是因为你有$data变量。
$this->data['data'] = $this->mdaftar->get_daftar_detail($this->data['id_user']);
您使用$data - foreach。
<?php foreach ($prodi as $data) :?>
你需要改变它。
<?php foreach ($prodi as $prodi_data) :?>
<div class="field">
<label>Piih Prodi</label>
<input type="hidden" name="nama_prodi" value="
<?php echo $data->nama_prodi;?>">
<?php echo form_error('nama_prodi', '
<div class="ui red pointing label">', '</div>'); ?>
<select name="prodi" id="select_prodi">
<?php
foreach ($prodi as $prodi_data)
{
echo '<option value="'.$prodi_data->id_prodi.'">'.$prodi_data->nama_prodi.'</option>';
}
?>
</select>
</div>
<div class="field">
<label>Fakultas</label>
<div class="ui small left icon input">
<input type="text" disabled="disabled" id="fakultas" class="fakultas" placeholder="fakultas" name="nama_fakultas">
<i class="text file outline icon"></i>
</div>
</div>
<div class="field">
<label>Alamat</label>
<?php
// We need to check $data.
// Please comment what the result. Paste in comment.
var_dump($data);
?>
<textarea placeholder="text" name="alamat">
<?php echo $data->alamat;?>
</textarea>
<?php echo form_error('alamat', '<div class="ui red pointing label">', '</div>'); ?>
</div>
