有人可以看看我的代码并告诉我我做错了什么！
这是我的视图文件（html表单）
<?php $attrib = array('class'=>'form-horizontal col-lg-6')?>
<?php
if( isset( $_POST['save'] ) )
{
echo validation_errors('<div class="alert alert-danger">', '</div>');
}
?>
<?=form_open('basic_info/edit_basic', $attrib )?>
<div class="form-group">
<div class="input-group">
<div class="input-group-addon" id="label">First Name</div>
<input type="text" name="fname" class="form-control" value="<?=$fname?>">
</div>
</div>
<div class="form-group">
<div class="input-group">
<div class="input-group-addon" id="label">Middle Name</div>
<input type="text" name="mname" class="form-control" value="<?=$mname?>">
</div>
</div>
<div class="form-group">
<div class="input-group">
<div class="input-group-addon" id="label">Last Name</div>

</div>
<div class="form-group">
<div class="input-group">
<div class="input-group-addon" id="label">Gender</div>
<select name="gender" class="form-control">
<?php if( $gender == true ){ ?>
<option class="form-control" value="male" selected="selected">Male</option>
<option class="form-control" valu="female">Female</option>
<?php }else{ ?>
<option class="form-control" valu="female" selected="selected">Female</option>

我尝试了很多日期的变化，但它总是给出错误我很沮丧已经我没有看到该字段的问题（dob），请帮忙！
答案 0 :(得分：0)
获取您提供的代码并进行游戏。我得到了以下内容......
我做了一些细微的修改。发现差异！
视图 - test_form.php
<?php $attrib = array('class' => 'form-horizontal col-lg-6') ?>
<?php
if (isset($_POST['save'])) {
echo validation_errors('<div class="alert alert-danger">', '</div>');
}
?>
<?= form_open('welcome/form', $attrib); ?>
<div class="form-group">
<div class="input-group">
<div class="input-group-addon" id="label">Date of birth</div>
<input type="text" name="dob" class="form-control" value="<?= isset($dob)?$dob:'' ?>">
</div>

<div class="form-group">

所以我已将你的代码添加到welcome.php控制器中。
创建了一种测试日期格式 / welcome / test 的测试方法来测试你的回调代码和tarehe方法......来测试格式和值......
我有使用回调测试dob表单的表单方法 的欢迎/形式
您真的需要查看控制器的$ this-＆gt; form_validation_＆gt; run（）部分中的代码...为什么True和False条件的相同代码以及该代码的作用是什么？
这是你真正的问题吗？
