【问题描述】：
我认为这很简单，但我不知道如何执行。
我有一个包含一些数据的表单，并且我创建了另一个 php 文件来验证表单数据，但是如果验证失败，我无法将错误消息显示回表单中。我已经附上了这两个文件，但我不知道执行它很热:(
我的 form.php 看起来像
<form name="form1" method="post" action="process/process_add_page.php">
<fieldset>
<legend>Add Page</legend>
<table width="1056" height="365" border="1">
<tr>
<th width="77" scope="col">Page Title</th>
<th width="962" scope="col"><label for="page_title"></label>
<input type="text" name="page_title" id="page_title"><span style="color:#FF0000">* <?php echo $titleerror;?></span></th>
</tr>
<tr>
<th scope="row">Page Description</th>
<td><label for="page_description"></label>
<textarea name="page_description" class="ckeditor" id="page_description" cols="100" rows="5"></textarea></td>
</tr>
<tr>
<th scope="row">Seo Title</th>
<td><label for="seo_title"></label>
<input type="text" name="seo_title" id="seo_title"></td>
</tr>
<tr>
<th scope="row">Seo Description</th>
<td><label for="seo_description"></label>
<textarea name="seo_description" class="ckeditor" id="seo_description" cols="45" rows="5"></textarea></td>
</tr>
<tr>
<th scope="row">Page Order</th>
<td><label for="page_order"></label>
<input type="text" name="page_order" id="page_order"></td>
</tr>
<tr>
<th scope="row">Page Status</th>
<td><label for="page_status"></label>
<select name="page_status" id="page_status">
<option value="1">Active</option>
<option value="0">Inactive</option>
</select></td>
</tr>
<tr>
<th colspan="2" scope="row"><input type="submit" name="btnsubmit" id="btnsubmit" value="Submit"></th>
</tr>
</table>
<p> </p>
</fieldset>
</form>
我的 process_add_pages.php 看起来像这样
<?php
require_once('../../classes/database.php');
require_once('../../classes/pages.php');
require_once('../../classes/redirect.php');
$objPage=new Page();
$titleerror='';
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if(empty($_POST['page_title'])){
$titleerror = "Title is required";
echo $titleerror;
}else
{
$page_title=mysqli_real_escape_string($objPage->conxn,$_POST['page_title']);
if (!preg_match("/^[a-zA-Z ]*$/",$page_title)) {
$titleerror = "Only letters and white space allowed";
}
}
$page_description=mysqli_real_escape_string($objPage- >conxn,$_POST['page_description']);
$seo_title=mysqli_real_escape_string($objPage->conxn,$_POST['seo_title']);
$seo_description=mysqli_real_escape_string($objPage->conxn,$_POST['seo_description']);
$page_order=mysqli_real_escape_string($objPage->conxn,$_POST['page_order']);
$page_status=mysqli_real_escape_string($objPage->conxn,$_POST['page_status']);
}
$objPage->setPage_title($page_title);
$objPage->setPage_description($page_description);
$objPage->setSeo_title($seo_title);
$objPage->setSeo_description($seo_description);
$objPage->setPage_status($page_status);
if($objPage->addPage()){
new Redirect('../index.php?page=page&action=view&success=The page has been created');
}else{
new Redirect('../index.php?page=page&action=view&error=The page could not be created');
}
?>
【问题讨论】：
-
你为什么使用两个分开的文件？
-
因为我在管理代码的唯一文件夹中拥有所有表单处理文件
