在另一个php脚本中验证表单?
我想知道,如果表单中的操作设置为另一个脚本,是否可以管理错误 ajoudesign.php在另一个php脚本中验证表单?,php,forms,Php,Forms,我想知道,如果表单中的操作设置为另一个脚本,是否可以管理错误 ajoudesign.php <FORM name='devis' method='POST' action='ajoutDevisScript.php' id='form'> <label for="client">Client</label> <input type='text' id='client' name='client'> <span class="error">
<FORM name='devis' method='POST' action='ajoutDevisScript.php' id='form'>
<label for="client">Client</label>
<input type='text' id='client' name='client'>
<span class="error">* <?php echo $clientErr;?></span>
</FORM>
那么,如果输入为空,是否可以在范围中显示我的错误?还是说没有办法用其他脚本作为动作
谢谢 session_start();
session_start();
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if(empty($_POST['client'])) {
$clientErr = "ERROR";
$_SESSION['error] = $clentErr;
header('location:ajoutDevis.php');
} else $client = $_POST['client'];
In your ajoutDevis.php file
session_start();
$clientErr = ($_SESSION['error']!='')?$_SESSION['error']:'';
<FORM name='devis' method='POST' action='ajoutDevisScript.php' id='form'>
<label for="client">Client</label>
<input type='text' id='client' name='client'>
<span class="error">* <?php echo $clientErr;?></span>
</FORM>
如果($\服务器[“请求\方法”]=“发布”){
if(空($_POST['client'])){
$clienter=“错误”;
$\会话['error]=$clenter;
标题('location:ajoutdesign.php');
}else$client=$_POST['client'];
在您的ajoudesign.php文件中
会话_start();
$clientErr=($\u会话['error']!=“”)?$\u会话['error']:“”;

您需要执行以下操作:
在页面底部的ajoutdesignscript.php页面上添加表单代码
<?php if(!empty($clientErr)) { ?>
<FORM name='devis' method='POST' action='ajoutDevisScript.php' id='form'>
<label for="client">Client</label>
<input type='text' id='client' name='client'>
<span class="error">* <?php echo $clientErr;?></span>
</FORM>
<?php } ?>

这将检查错误变量中是否有任何错误。它将在同一页上显示有错误的表单。是的,可以使用
$\u会话变量在会话期间存储值,并使用header()
函数将用户从第二个脚本重定向回第一个脚本。
假设两个文件都在根目录中,ajoudevident.php:
<?php
session_start();
?>
<FORM name='devis' method='POST' action='ajoutDevisScript.php' id='form'>
<label for="client">Client</label>
<input type='text' id='client' name='client'>
<?php if (isset($_SESSION['clientErr'])) : ?>
<span class="error">* <?php echo $_SESSION['clientErr'] ?></span>
<?php endif; ?>
</FORM>
<?php
session_start();
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if(empty($_POST['client'])) {
$_SESSION['clientErr'] = "ERROR";
header('Location: ajoutDevis.php');
} else {
$client = $_POST['client'];
}
}
?>

和ajoutdesignscript.php:
<?php
session_start();
?>
<FORM name='devis' method='POST' action='ajoutDevisScript.php' id='form'>
<label for="client">Client</label>
<input type='text' id='client' name='client'>
<?php if (isset($_SESSION['clientErr'])) : ?>
<span class="error">* <?php echo $_SESSION['clientErr'] ?></span>
<?php endif; ?>
</FORM>
<?php
session_start();
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if(empty($_POST['client'])) {
$_SESSION['clientErr'] = "ERROR";
header('Location: ajoutDevis.php');
} else {
$client = $_POST['client'];
}
}
?>
我建议您仅在需要时打印span
。我还建议您检查括号以避免PHP错误。如果要使用会话变量显示错误,请记住在显示后取消链接/删除会话变量,否则错误将继续显示。请尝试:取消链接($\u session['error')); ;)
