nl2br against me?

[EPCtech]

Hello,

For some reason, nl2br() is making too many line breaks after being replaced. When creating blogs on my website, you experience a bad problem.

 

I use nl2br when finishing the editing and str_replace so that the users don't see the "<br />" tags but in this process the number of line breaks doubles. Especially when editing my homepage and such (my homepage gathers data from a database for it's text; It doesn't use HTML for the text). Please help!

 

Best Regards,

Code? Without see what you're doing, it's hard for us to help.

Ok, sorry, I tend to think I can summarize my problem with words. It always fails.

 

Now, this is when creating a page:

 

$name=mysql_real_escape_string(stripslashes($_POST['name']));
$content=mysql_real_escape_string(nl2br($_POST['content']));
mysql_query("INSERT INTO pages (name,content) VALUES ('".$name."','".$content."')");
echo "Page created";

 

This is editing a page, before hitting submit:

 

$page1=$_GET['page'];
$sql=mysql_query("SELECT content FROM pages WHERE name='".$page1."'");
list($page)=mysql_fetch_array($sql);
$page=str_replace("<br />","\n",$page);

 

And this is editing after hitting submit:

$page2=$_GET['page'];
$content=mysql_real_escape_string(nl2br($_POST['content']));
mysql_query("UPDATE pages SET content='".$content."' WHERE name='".$page2."'");
echo "Page updated!";

 

When created, the page is like this:

Hello.

This is a test.

 

Then I click edit, change nothing and hit submit.

Hello.

 

This is a test.

 

Why does this happen?

Do not use nl2br() when you store the data, only when you display the data. The function does not replace "\n" with a "<br />", it inserts the "<br />" next to the "\n", therefore you are adding an extra "\n" with your str_replace.
