如何回显MySQL数据库中的换行符? [英] How do I echo line breaks from a MySQL database?
问题描述
我已经创建了一个简单的墙贴功能,例如在FaceBook上.
I have created a simple wall post feature, like on FaceBook.
用户写一个帖子,该帖子被提交到数据库,然后回显到网站上;一切正常.
A user writes a post, the post is submitted to the database and then echoed back onto the website; that all works.
唯一的问题是,当文本回显到网站上时,换行符不是.所以,我输入:
The only issue is, when the text is echoed back onto the website the line break isn't. So, I typed:
嘿,这是一个帖子.
"Hey this is a post.
这是一个新段落"
,它显示为:
嘿,这是帖子.这是一个新段落"
"Hey this is a post. Here is a new paragraph"
我在这里看到一些帖子说要使用nl2br()函数并在新行中输入/n,但是我真的不希望我的用户每次想要一个新行时都必须写"/n"行,他们只需要按键盘上的Enter键即可.
I've seen a few posts here saying to use the nl2br() function and input /n for a new line, however I really don't want my users to have to write '/n' everytime they want a new line, they should just have to press the enter key on the keyboard.
换行符存储在数据库中,所以我不知道为什么不将其回显.有人可以帮忙吗?
The line break is stored in the database, so I have no idea why it isn't echoed out. Can anyone help?
不确定该代码是否必要,但我会以防万一.
Not sure if the code will be necessary but I'll post it just in case.
while($wallposts = mysql_fetch_assoc($getwallposts)) {
$postid = $wallposts['id'];
$postedby_username = $wallposts['postedby'];
$wallpostdate = $wallposts['dateposted'];
$wallpost = $wallposts['post'];
$querypostedby_info = mysql_query("SELECT * FROM `users` WHERE `username`='$postedby_username'");
//get the info above
if (mysql_num_rows($querypostedby_info)===1) {
$getpostedby_info = mysql_fetch_assoc($querypostedby_info);
$postedby_id = $getpostedby_info['id'];
$postedby_profilepicture = $getpostedby_info['profilepicture'];
}
//display the posts
$wallpoststicker =
"
<div id='wallpost-container'>
<div id='wallpost-header'>
<img src='$postedby_profilepicture'><div id='wallpost-header-by'><a href='/profile.php?id=$postedby_id'>$postedby_username</a> said:</div>
<div id='wallpost-date'>• $wallpostdate</div>
</div>
<div id='wallpost-content'>
$wallpost
</div>
</div>
";
}
推荐答案
PHP函数
nl2br
将换行符转换为"<br>
"中断.
因此,$wallpost=nl2br($wallpost);
应该完成任务.
PHP function
nl2br
converts newlines to "<br>
" breaks.
So, $wallpost=nl2br($wallpost);
should accomplish the task.
