Replacing text with smilies

Radon3k

I have a small news posting feature in which on a page that I go to, to post the news, there is a text field for the title, and a textarea for the actual news post. What I would like to do, is in that textarea, is if I type 🙂 it will be replaced with a smilie face. How do I go about doing this? Thanks. 🙂

batman

$smile = str_replace("`: )`", "<img src='smile.gif'>");
//take away space between : and )

All I have to do now is type 🙂 and it will show the smilie?

Your code below is replacing the phpbuilders smile with your own. This is what the code should look like:

<form method="post" action="<?php echo($PHP_SELF); ?>" id="addnews" name="addnews"> 
                    News Title: <br /> 
                    <input type="text" name="title" id="title" /> <br /> <br /> 
                    News: <br /> 
                    <textarea name="news" id="news" rows="10" cols="40"> 
                    </textarea> <br /> 
                    <input type="submit" name="submit" id="submit" value="Post"> <br /> <br /> 
                    <?php 
                    // DB Connection info                     

if($_POST['submit'] == "Post") 
                    { 
                        $title = stripslashes($title); 
                        $news = str_replace("`: )`","<img src='/forum/images/smilies/smile.gif' />"); 
//replace the space between the : and )
                        $addnews = mysql_query("INSERT INTO news SET 
                                            title = '$title', 
                                            news = '$news', 
                                            newsdate = NOW(), 
                                            newstime = NOW()");?>

Hi,

I noticed that, which is why i deleted my post. I tried that and on the page that displays the news, but it just shows the colon and parenthesis. What should I do?

batman

Ok...that's because you have to give it something to use.
Try something like this:

$string = $_POST['news'];

$news = str_replace("`: )`","<img src='/forum/images/smilies/smile.gif' />", $string);  

//replace the space between the : and )

Radon3k

For some reason that made it to where no text in the $news variable shows. 🙁

batman

Man, you are too fast, you don't give me any time to update my posts. 🙂 Try my last post with code.

Radon3k

Sorry about that. 🙂 I tried the updated code as well and now it at least shows the text, but again, no smilie.

batman

You have a sample url?

Radon3k

Here. The page in which you post the news is viewable to my IP only, but if you need to see it for some reason I can take that off. I appreciate your help. 🙂

batman

Try this:


$string = $_POST['news']; 

$news = str_replace(": )","<img src='/forum/images/smilies/smile.gif' />", $string);   

//replace the space between the : and )

Radon3k

Like this: : ) (no space) I get an error when submitting.
Like this: : ) (no space) no error but no smilie.

batman

$string = $_POST['news'];  

$news = str_replace("%: )%","<img src='/forum/images/smilies/smile.gif' />", $string);    

//replace the space between the : and )

Radon3k

That's not working either. 🙁 I'm not sure what to do, would something like ereg_replace work instead of str_replace or are they roughly the same?

batman

They are not quit the same and I was about to suggest that.
Try this:

$string = $_POST['news'];
$smile = ": )";
//replace the space between the : and )  

$url = "<img src='/forum/images/smilies/smile.gif' />";

$news = preg_replace($smile, $url, $string);

See if that works.

If that doesn't work, then try adding the ` around the : )

: )

Radon3k

I tried both of those and ereg_replace and it's not working. I didn't realize it was this hard, I thought the x_replace would work just fine. 🙁

batman

Well, I'm fresh out of ideas. 🙂 I would dl a forum of some kind and look through the codeing and grab the part of the code that they wrote to do it.

Radon3k

Thanks for your help. 🙂

Anybody else know how?
