我一直在试图解决这个小问题,并准备好把我的头发拉出来。我是一名设计师,而不是一名程序员,但我已经为我的学校在php中创建了一个提交表单。这是我正在研究的测试表格:
http://www.inrf.uci.edu/php-form-test/
我想要做的是当一个人选择外部用户时,他们应该被要求填写他们的公司名称。当有人选择内部用户时,他们需要填写他们的组/ PI名称。这不行。当我选择内部时,它应该只需要组/ PI名称而不是公司名称。我将不胜感激任何帮助。谢谢!
这是我的PHP代码:
// internal selected (group pi)
if ($userType == 'internal') {
$internalChecked = ' checked="checked" ';
} else {
if(trim($_POST['grpPI']) === '') {
$grpPIError = '<span class="error">Please enter your group or PI name.</span>';
$hasError = true;
} else {
$grpPI = trim($_POST['grpPI']);
}
}
}
// external selected (company name)
if ($userType == 'external') {
$externalChecked = ' checked="checked" ';
} else {
if(trim($_POST['companyName']) === '') {
$companyNameError = '<span class="error">Please enter your company name.</span>';
$hasError = true;
} else {
$companyName = trim($_POST['companyName']);
}
}
和HTML在这里:
<table class="usertype" id="usertype">
<tr>
<td colspan="2">
<input type="radio" name="userType" value="external" <?php echo $externalChecked; ?>>External
<select name="externalSelect" size="1">
<option selected="selected">Select</option>
<option>Academic</option>
<option>Non-Profit</option>
<option>Commercial</option>
</select><?php if($externalError != '') { ?><span class="error"><?=$externalError;?></span><?php } ?></td>
</tr>
<tr>
<td colspan="2"><label for="companyName">Company Name:</label>
<input type="text" size="40" name="companyName" id="companyName" value="<?php if(isset($_POST['companyName'])) echo $_POST['companyName'];?>" />
<?php if($companyNameError != '') { ?>
<span class="error"><?=$companyNameError;?></span><?php } ?></td>
</tr>
<tr>

答案 0 :(得分:1)
请注意你的逻辑:
if ($user == 'internal') {
...
} else {
... check for empty field ...
}
因此,如果用户选择&#39;外部&#39;,那么&#34;仅内部&#34;字段将为空,并强制出错。为什么要设置内部字段,因为用户选择&#34;外部&#34;。
同样,对于external
检查,仅限内部字段将为空,您会强制执行其他错误。
您需要else
子句将这两个if()
语句绑定在一起,以便只执行两个代码路径中的一个:
if ($user == 'internal') {
... do internal-only checks ...
} else if ($user == 'external') {
... do external-only checks ...
} else {
... $user is undefined type, "zomg how'd you get here" error handling.
}
