php – 从mysql插入语句中删除链接？

2024年1月28日 134次阅读

我想知道是否有人可以请求帮助,我正在运行
MySQL插入查询,因此当用户填写表单时,它会将内容插入到数据库中.但是,我试图这样做,以便我可以删除/阻止链接(URL)插入.

我正在尝试这个,但我是MySQL的新手,我无法让它工作,我不确定我做得对,如果有人可以提供帮助,我将不胜感激.

提前致谢,

<?php ob_start(); ?>
 <?php 
// check if the review form has been sent
if(isset($_POST['review_content']))
if(isset($_POST['review_recipient']))
{
    $content = $_POST['review_content'];
    $review_recipient = $_POST['review_recipient'];
        //We remove slashes depending on the configuration
        if(get_magic_quotes_gpc())
        {
                $content = stripslashes($content);
                $review_recipient = stripslashes($review_recipient);
        }
        //We check if all the fields are filled
        if($_POST['review_content']!='')
        if($_POST['review_recipient']!='')
        {


            {

                $forbidden = array('<[\w.]+@[\w.]+>', '<\w{3,6}:(?:(?://)|(?:\\\\))[^\s]+>', '#<.*?>([^>]*)</a>#i');
$matches  = array('****', '****', '****');
$post     =  preg_replace($forbidden, $matches, $post);


            $sql = "INSERT INTO ptb_reviews (id, from_user_id, from_guest, to_user_id, content) VALUES (NULL, '-1', '".$review_recipient."', '".$profile_id."', '".$content."');";
            mysql_query($sql, $connection);

            $_SESSION['message']="<div class=\"infobox-wallpost\"><strong>Thank You</strong> - Your review has been sent and is awaiting approval.</div><div class=\"infobox-close4\"></div>"; 
header("Location: {$_SERVER['HTTP_REFERER']}");

} } } } } ?>

更新：

好吧所以我试图这样做,但它仍然允许显示网址

<?php ob_start(); ?>
 <?php 
// check if the review form has been sent
if(isset($_POST['review_content']))
if(isset($_POST['review_recipient']))
{
    $content = $_POST['review_content'];
    $review_recipient = $_POST['review_recipient'];
        //We remove slashes depending on the configuration
        if(get_magic_quotes_gpc())
        {
                $content = stripslashes($content);
                $review_recipient = stripslashes($review_recipient);

                $regex = "/(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w\.-]*)*\/?/";
$replacement = "[blocked url]";
$review_recipient = reg_replace($regex,$replacement,$_POST['review_recipient']);
$profile_id = intval($_POST['profile_id ']); //dont know how you get this
$content = reg_replace($regex,$replacement,$_POST['review_content']);
        }
        //We check if all the fields are filled
        if($_POST['review_content']!='')
        if($_POST['review_recipient']!='')


        {


            {


            $sql = "INSERT INTO ptb_reviews (id, from_user_id, from_guest, to_user_id, content) VALUES (NULL, '-1', '".$review_recipient."', '".$profile_id."', '".$content."');";
            mysql_query($sql, $connection);

            $_SESSION['message']="<div class=\"infobox-wallpost\"><strong>Thank You</strong> - Your review has been sent and is awaiting approval.</div><div class=\"infobox-close4\"></div>"; 
header("Location: {$_SERVER['HTTP_REFERER']}");

} } } } } ?>

最佳答案 你遇到的问题是你在get_magic_quotes_gpc()调用中得到了正则表达式检查,Joel的代码也将reg_replace作为拼写错误,否则就行了(如果你把它放在魔术引号之外).

这是一个完全更新的脚本供您试用.

<?php

ob_start();

// check if the review form has been sent
if(isset($_POST['review_content'])) {
    if(isset($_POST['review_recipient'])) {
        $content = $_POST['review_content'];
        $review_recipient = $_POST['review_recipient'];

        //We remove slashes depending on the configuration
        if(get_magic_quotes_gpc()) {
                $content = stripslashes($content);
                $review_recipient = stripslashes($review_recipient);
        }

        $regex = "/(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w\.-]*)*\/?/";
        $replacement = "[blocked url]";
        $review_recipient = preg_replace($regex,$replacement,$_POST['review_recipient']);
        //$profile_id = intval($_POST['profile_id']); //dont know how you get this
        $content = preg_replace($regex,$replacement,$_POST['review_content']);


        //We check if all the fields are filled
        if($_POST['review_content']!='') {
            if($_POST['review_recipient']!='') {

                $sql = "INSERT INTO ptb_reviews (id, from_user_id, from_guest, to_user_id, content) VALUES (NULL, '-1', '".$review_recipient."', '".$profile_id."', '".$content."');";
                mysql_query($sql, $connection);

                $_SESSION['message']="<div class=\"infobox-wallpost\"><strong>Thank You</strong> - Your review has been sent and is awaiting approval.</div><div class=\"infobox-close4\"></div>";

                header("Location: {$_SERVER['HTTP_REFERER']}");
            }
        }

    }

}

?>

如果你想阻止特定的单词,你也可以添加如下内容：

$regex2 = "/(.*)\b(word1|word2|word3)\b(.*)/";
$replacement2 = "[blocked word]";

然后将preg_replace更改为以下内容：

$content = preg_replace(Array($regex, $regex2),Array($replacement, $replacement2),$_POST['review_content']);
