Question

我正在尝试为我正在处理的网站创建自定义博客系统，我创建了所有系统但是当我尝试将表单插入数据库时，脚本会执行，但数据不会保存到数据库。有些字段确实包含大量文本，使用TinyMCE进行格式化可能会出现问题吗？当我使用较少量的文本进行测试时，它可以正常工作。

PHP脚本：

$conn = connect();
$action = $_GET['a'];
$id = $_GET['id'];
switch($action) {
case 'delete':
    $sql = "DELETE FROM articles WHERE id='$id'";
    if(mysql_query($sql)) {
        echo "<script type='text/javascript'> alert('Article Deleted'); </script>";
        header("Location: manage.php");
    }   
break;

case 'add':
if(isset($_POST['submit'])) {
$slug = $_POST['slug'];
$datecreated = $_POST['datecreated'];
$datepublish = $_POST['datepublish'];
$author = $_POST['author'];
$status = $_POST['status'];
$title = $_POST['title'];
$miniexcerpt = $_POST['miniexcerpt'];
$teaser = $_POST['teaser'];
$body = $_POST['body'];
    $sql = "INSERT INTO articles (slug,datecreated,datepublish,author,status,title,miniexcerpt,teaser,body) values ('$slug','$datecreated','$datepublish','$author','$status','$title','$miniexcerpt','$teaser','$body')";
    if(mysql_query($sql)) {
        echo "<script type='text/javascript'> alert('Article Added'); </script>";
        header("Location: manage.php");
    }
}
break;

case 'edit':
if(isset($_POST['submit'])) {
$slug = $_POST['slug'];
$datecreated = $_POST['datecreated'];
$datepublish = $_POST['datepublish'];
$author = $_POST['author'];
$status = $_POST['status'];
$title = $_POST['title'];
$miniexcerpt = $_POST['miniexcerpt'];
$teaser = $_POST['teaser'];
$body = $_POST['body'];
    $sql = "UPDATE articles SET slug='$slug',datecreated='$datecreated',datepublish='$datepublish',author='$author',status='$status',title='$title',miniexcerpt='$miniexcerpt',teaser='$teaser',body='$body' WHERE id='$id'";
    if(mysql_query($sql)) {
        echo "<script type='text/javascript'> alert('Article Updated'); </script>";
        header("Location: manage.php");
    }
    }
break;  

}

$conn = connect();
$action = $_GET['a'];
$id = $_GET['id'];
switch($action) {
case 'publish':
    $sql = "UPDATE articles SET status='published' WHERE id='$id'";
    if(mysql_query($sql)) {
        echo "<script type='text/javascript'> alert('Article Published'); </script>";
        header("Location: manage.php");
    }   
break;
}

HTML表单：

检查你的php.ini。某些参数会影响POST有效负载大小。

post_max_size整数 设置允许的后期数据的最大大小。此设置也会影响文件上载。要上传大文件，此值必须大于upload_max_filesize。一般来说，memory_limit应该大于post_max_size。使用整数时，该值以字节为单位。也可以使用本FAQ中描述的速记符号。如果发布数据的大小大于post_max_size，则$ _POST和$ _FILES超全局变量为空。这可以以各种方式跟踪，例如，通过将$ _GET变量传递给处理数据的脚本，即检查是否设置了$ _GET ['processed']。
