我正在开发一个系统，可以在出现错误时回显diff表单。 我制作了一个包含所有字段的表单，然后我为每个字段再制作了8个表单。（如果他没有填充第一个字段echo $ form_1;如果他没有填充第二个字段echo $ form_2和等等，但是当我尝试测试我的代码时，它会显示一个空白页面。
register.php：
<?php
require 'regforms.php';
$btsubmit = isset($_POST["btsubmit"]) ;
if ($btsubmit) {
$ptuser = $_POST["ptuser"] ;
$ptemail = $_POST["ptemail"] ;
$ptveremail = $_POST["ptveremail"] ;
$ptpass = $_POST["ptpass"] ;
$ptverpass = $_POST["ptverpass"] ;
$ptsecquest = $_POST["ptsecquest"] ;
$ptsecans = $_POST["ptsecans"] ;
$cpantibot = isset($_POST['cpantibot']) ;
if (empty($ptuser) && empty($ptemail) && empty($ptveremail) && empty($ptpass) && empty($ptverpass) && empty($ptsecquest) && empty($ptsecans) && empty($cpantibot)) {
echo $form_1;
} else if (empty($ptuser) && empty($ptemail) && empty($ptveremail) && empty($ptpass) && empty($ptverpass) && empty($ptsecquest) && empty($ptsecans) && $cpantibot) {
echo $form_2;
} else if (empty($ptuser) && empty($ptemail) && empty($ptveremail) && empty($ptpass) && empty($ptverpass) && empty($ptsecquest) && $ptsecans && $cpantibot) {

} else if (empty($ptuser) && empty($ptemail) && empty($ptveremail) && empty($ptpass) && empty($ptverpass) && $ptsecquest && $ptsecans && $cpantibot) {

检查您的格式。查看脚本的结尾以及第一个IF语句如何关闭/未关闭。你没有关闭最后一个[elseif]语句！试试这个：
<?php
require 'regforms.php';
$btsubmit = isset($_POST["btsubmit"]) ;
if ($btsubmit) {
$ptuser = $_POST["ptuser"] ;
$ptemail = $_POST["ptemail"] ;
$ptveremail = $_POST["ptveremail"] ;
$ptpass = $_POST["ptpass"] ;
$ptverpass = $_POST["ptverpass"] ;
$ptsecquest = $_POST["ptsecquest"] ;
$ptsecans = $_POST["ptsecans"] ;
$cpantibot = isset($_POST['cpantibot']) ;
if (empty($ptuser) && empty($ptemail) && empty($ptveremail) && empty($ptpass) && empty($ptverpass) && empty($ptsecquest) && empty($ptsecans) && empty($cpantibot)) {
echo $form_1;
} else if (empty($ptuser) && empty($ptemail) && empty($ptveremail) && empty($ptpass) && empty($ptverpass) && empty($ptsecquest) && empty($ptsecans) && $cpantibot) {
echo $form_2;
} else if (empty($ptuser) && empty($ptemail) && empty($ptveremail) && empty($ptpass) && empty($ptverpass) && empty($ptsecquest) && $ptsecans && $cpantibot) {
echo $form_3;
} else if (empty($ptuser) && empty($ptemail) && empty($ptveremail) && empty($ptpass) && empty($ptverpass) && $ptsecquest && $ptsecans && $cpantibot) {
echo $form_4;
} else if (empty($ptuser) && empty($ptemail) && empty($ptveremail) && empty($ptpass) && $ptverpass && $ptsecquest && $ptsecans && $cpantibot) {
echo $form_5;
} else if (empty($ptuser) && empty($ptemail) && empty($ptveremail) && $ptpass && $ptverpass && $ptsecquest && $ptsecans && $cpantibot) {
echo $form_6;
} else if (empty($ptuser) && empty($ptemail) && $ptveremail && $ptpass && $ptverpass && $ptsecquest && $ptsecans && $cpantibot) {
echo $form_7;
} else if (empty($ptuser) && $ptemail && $ptveremail && $ptpass && $ptverpass && $ptsecquest && $ptsecans && $cpantibot) {
echo $form_8;
} else if ($ptuser && $ptemail && $ptveremail && $ptpass && $ptverpass && $ptsecquest && $ptsecans && $cpantibot) {
echo 'ok';

尝试更好地构建代码。以下是我建议你处理的事情：
请注意，这是假设您使用的是PHP 5.4+并且您有短标签。如果没有，请将<?=替换为<?php echo，它应该可以正常工作。
<?php
$btsubmit = isset($_POST["btsubmit"]) ;
$fieldIsRequired = '<font color="red">This field is required.</font>';
$passwordMismatch = '<font color="red">Passwords mismatch.</font>';
$emailMismatch = '<font color="red">Emails don\'t match.</font>';
if ($btsubmit) {
$ptuser = $_POST["ptuser"] ;
$ptemail = $_POST["ptemail"] ;
$ptveremail = $_POST["ptveremail"] ;
$ptpass = $_POST["ptpass"] ;
$ptverpass = $_POST["ptverpass"] ;
$ptsecquest = $_POST["ptsecquest"] ;
$ptsecans = $_POST["ptsecans"] ;
$cpantibot = isset($_POST['cpantibot']) ;
$errors[] = array();
if (empty($ptuser)) $errors['ptuser'] = $fieldIsRequired;
if (empty($ptemail)) $errors['ptemail'] = $fieldIsRequired;
if (empty($ptveremail)) $errors['ptveremail'] = $fieldIsRequired;
if (empty($ptpass)) $errors['ptpass'] = $fieldIsRequired;
if (empty($ptverpass)) $errors['ptverpass'] = $fieldIsRequired;
if (empty($ptsecquest)) $errors['ptsecquest'] = $fieldIsRequired;
if (empty($ptsecans)) $errors['ptsecans'] = $fieldIsRequired;
if (!$cpantibot) $errors['cpantibot'] = $fieldIsRequired;
// handling special case
if (!empty($ptpass) && !empty($ptverpass) && $ptpass != $ptverpass) {
$errors['ptpass'] = $passwordMismatch;
}
if (!empty($ptemail) && !empty($ptveremail) && $ptemail != $ptveremail) {
$errors['ptemail'] = $emailMismatch;
}
if (count($errors) == 0) {
// No errors!
echo '<h3>Form is all ok!</h3>';
}
}
?>
<form action="register.php" method="POST">
<table>
<tr>
<td colspan="3"><h3>Basic information</h3></td>

<tr>

好的，如果您正在尝试验证您可能想要的表单字段 a）对输入进行消毒 b）简化代码
您不需要8种不同的表单，只需要一个表格并回显无法验证的字段旁边的“缺失字段”变量值。
你可能想要从这样的事情开始（或者更简化它并从中做出一个循环）：
<?php
require 'regforms.php';
$btsubmit = $ptuser = $ptemail = $ptveremail = $ptpass = $ptverpass = $ptsecquest = $ptsecans = $cpantibot = '';
$btsubmit = isset($_POST['btsubmit']) ? filter_var($_POST['btsubmit'], FILTER_SANITIZE_STRING) : 'failed';
if (!empty($btsubmit) && $btsubmit != ' ' && $btsubmit != 'failed') {
$ptuser = isset($_POST['ptuser']) ? filter_var($_POST['ptuser'], FILTER_SANITIZE_STRING) : 'failed';
$ptemail = isset($_POST['ptemail']) ? filter_var($_POST['ptemail'], FILTER_SANITIZE_EMAIL) : 'failed';
$ptveremail = isset($_POST['ptveremail']) ? filter_var($_POST['ptveremail'], FILTER_SANITIZE_EMAIL) : 'failed';
$ptpass = isset($_POST['ptpass']) ? filter_var($_POST['ptpass'], FILTER_SANITIZE_STRING) : 'failed';
$ptverpass = isset($_POST['ptverpass']) ? filter_var($_POST['ptverpass'], FILTER_SANITIZE_STRING) : 'failed';
$ptsecquest = isset($_POST['ptsecquest']) ? filter_var($_POST['ptsecquest'], FILTER_SANITIZE_STRING) : 'failed';
$ptsecans = isset($_POST['ptsecans']) ? filter_var($_POST['ptsecans'], FILTER_SANITIZE_STRING) : 'failed';
$cpantibot = isset($_POST['cpantibot']) ? filter_var($_POST['cpantibot'], FILTER_SANITIZE_STRING) : 'failed';
if($ptuser == 'failed'){ $ptuserErr = 'Missing field!'; }
if($ptemail == 'failed'){ $ptemailErr = 'Missing field!'; }
if($ptveremail == 'failed'){ $ptveremailErr = 'Missing field!'; }
if($ptpass == 'failed'){ $ptpassErr = 'Missing field!'; }
if($ptverpass == 'failed'){ $ptverpassErr = 'Missing field!'; }
if($ptsecquest == 'failed'){ $ptsecquestErr = 'Missing field!'; }
if($ptsecans == 'failed'){ $ptsecansErr = 'Missing field!'; }
if($cpantibot == 'failed'){ $cpantibotErr = 'Missing field!'; }
然后在HTMLform中使用以下内容：
<td>Username : </td>
<td><input type = "text" name = "ptuser"><font color = "red" ><?php echo $ptuserErr; ?></font></td>
