multiple ereg_replace

dotty

Hi,

I'm trying to use smilies in my guestbook so I need to replace the smilie code with the appropriate image and then insert into database table. I'm able to do this with one! How do I do this for each smilie?? :bemused:

$comment = ereg_replace( ":)","<img src=guestbook_images/smiley1.gif border=0>",$_POST['comment']);

any help greatly appreciated!

$comment = addslashes($_POST['comment']);
$comment = ereg_replace( ":)","<img src=guestbook_images/smiley1.gif border=0>",$_POST['comment']);
$comment = ereg_replace( ":P","<img src=guestbook_images/smiley2.gif border=0>",$comment);

Just add another line beneath it. 🙂 The variable will overwrite itself with the new content.

You should also implement some type of variable protection to protect from SQL Injection. That's what the addslashes() function is for. But if you do that, you'll have to remember to use the stripslashes() function when displaying your code. 😉

using [man]preg_replace[/man] with two arrays would be nice and maintainable. Take a look at the example right under the usage notes.

For this, [man]str_replace[/man] would be enough, and wouldn't require escaping metacharacters.

Hi,

Thanks for the help guys. I had tried the preg array example you mention Drakla but it didn't work. Your solution DennisP works great! I hadn't thought of using the variable instead of the $_POST on the second and subsequent lines, and of course it was outputting everything twice!

Yippee.. Now I have smilies! 🙂 🙂 🙂

Great forum help as always!!
