Smileys (stupid question)

[kiara]

I have tested smileys put in smilyes in my blog/news script but since I´m total new to PHp I can´t figure out if I have to put the code in to the blog file or inte to the submit.php 🙁
And I thin I might have wrong type of code to.

Somebody can give me a hint how to make it?

You didn't actually state what you are trying to do, so I will guess that you are trying to replace the smiley text with a smiley graphic.

What you want to do is run the text through a str_replace function, and simply stick an <img> tag inplace of the text.

You want to replace the text when the info is being DISPLAYED, not as you enter it in the database. Since there are several replacements you will need to make each time, I suggest you create a function to do it.

function text2smilies($input)
{
$output = str_replace(":)", "<img src=\"happy.gif\">", $input);
$output = str_replace(";)", "<img src=\"wink.gif\">", $output);
//etc etc
RETURN $output;
}

Then wherever you normally have the code to display the text, you would run this function.

eg: echo( text2smilies($table_content) );

I don't know why, but my code is being screwed up by the forum. You'll have to fix the "s because the way it is displayed is wrong.

Offtopic...but, if I try to escape characters in php tags, the \s don't show up. Why?

[kiara]

Sorry for my bad explain 🙂 I want like this : ) to show up like smileys image in my blog/news script but I´m confused if I have to put that code in the blog.php or in the submit.php code. Submit.php is part of the formscript that inserts the news/text into the blog.php

Leave the text as 🙂 all the time, except when actually displaying it. So when adding to a database or whatever, it should be 🙂.

If it's a news script you're doing for example, it's only when you go to the viewnews.php or whatever, where it'd get the text from the database then display it. You'd use Pig's function right before you display it.

I hope you could make sense of that. 😛

[kiara]

I still don´t get it 🙁

[BuzzLY]

Put the code to replace : ) with 🙂 in blog.php. When submitted and stored in the database, it should be stored as : ). Only when displaying it on the screen in your blog should it be converted to the image: 🙂

Get it? 🙂

If you are not using a database (why not???), and instead are modifying blog.php, then do the conversion before inserting it into blog.php. Inside blog.php should be the <image> tag, not the actual smiley : )

[Pig]

anyone who replies to this, make sure you check the disable smilies box when you reply! Way to confusing otherwise!

The only change you need to make, is to put that code WHERE THE DATA IS DISPLAYED. Whatever the page is that you view the information on is where the code should go.

Sorry i´m total new to PHP and databses 🙂 Yes I use database to store the al the content i blog.php and I tryd to put in the smileys code in to the blog but it would not work. I think i made it wrong

This is the blog.php code

$q = "SELECT * from blog order by date desc ";
$result= mysql_query($q, $connection) or die 
("Could not execute query : $q." . mysql_error());

// dynamic navigation variables
$rows_per_page=5; // adjust the number here to display number of entries per page 
$total_records=mysql_num_rows($result);
$pages = ceil($total_records / $rows_per_page);
mysql_free_result($result);

if (!isset($screen))
$screen=0;
$start = $screen * $rows_per_page;
$q .= "LIMIT $start, $rows_per_page";
$result= mysql_query($q, $connection) or die 
("Could not execute query : $q." . mysql_error());


while ($row=mysql_fetch_array($result))
{
$id=$row["id"];
$name=$row["name"];
$email=$row["email"];
$entry=$row["entry"];
$date=$row["date"];
$icon=$row["icon"]; 
$title=$row["title"]; 



?>

<table width="100%" border="0" cellspacing="1" cellpadding="0">
<tr>
<td><p class="head"><?php echo "$title"; ?></td>
</tr>
<tr>
<td><p class="content">
<?php echo "$entry"; ?>
<p class="content">Posted by <a href="mailto:<?php echo "$email"; ?>"><b><?php echo "$name"; ?></a></b> on <?php echo "$date"; ?>.</p>
<p align="right">
<?php


$query = "select id from blog_comments where blog_id='$id'";
$ret = mysql_query($query);
$comment_num = mysql_num_rows($ret);


// add comments line here 
echo "<a href=\"#\""; 
echo " onClick=\"window.open('readcomments.php?id=$id', 'NewPopup', 'toolbar=no, location=no, status=no, scrollbars=yes, menubar=no, titlebar=no, height=600, width=425')\">"; 
echo "Comment</a> ( $comment_num )"; 
echo "</p>"; 

?>



</td>

   </tr>
    </table>
<br>

<div align="center">
<p>

<?php
}

// Display dynamic navigation here

// create the dynamic links
if ($screen > 0) {
$j = $screen - 1;
$url = "$PHP_SELF?screen=$j";
echo "<a href=\"$url\">Prev</a>";
}

// page numbering links now

for ($i = 0; $i < $pages; $i++) {
$url = "$PHP_SELF?screen=" . $i;
$j = $i + 1;
echo " | <a href=\"$url\">$j</a> | ";
}

if ($screen < $pages-1) {
$j = $screen + 1;
$url = "$PHP_SELF?screen=$j";
echo "<a href=\"$url\">Next</a>";
}

?>
</div>

and if got it right my slimeys code should look something like this?

function text2smilies($input)
{
$output = str_replace(":)","<img src=smilies/happy.gif>",$input);
$output = str_replace(":(","<img src=smilies/sad.gif>",$sout);

RETURN $output;
}

[Blob]

Sout? That should be $output. 🙂

It takes whatever you call it with,
text2smilies($post);
for example, calls it $input within the function, and then after the first str_replace it's known as $output within the function.

[Pig]

er... no. The correct code is below. the variables change because each statement runs the previous statements out put as it's input.

function text2smilies($input)
{
$output = str_replace(":)","<img src=smilies/happy.gif>",$input);
$output = str_replace(":(","<img src=smilies/sad.gif>",$output);

RETURN $output;
}

[kiara]

Ehh.. I think I leave it for the moment, this is beyound my intelligent at this point i feel 😃 Thanks anyway, I will try it out in the next days

That's really simple...

function text2smilies($input)
{
$output = str_replace(": )","<img src=smilies/happy.gif>",$input);
$output = str_replace(": (">","<img src=smilies/sad.gif>",$output);

RETURN $output;
}

$post = "Hello. I'm a test string. : ) How old am I? 5002? That can't be right... : (";
$post = text2smilies($post);
echo $post;

That's work. Of course, you wouldn't set the $post variable like that, you'd get the text from the database and run the function on that. It's eaaaaaassssssy. 🙂
