Hello everyone, i have a big problem with this $smarty->assign 
I found a nice script that would add smileys to my website in users comments but since the comments are coming from the database i am not sure how to make smarty replace the smiley characters with images.
Here is the script i am trying to get working:
function addSmilies($text) {
$codesToConvert = array(
':)' => '<img src="http://blog.sachinkraj.com/images/smilies/smile.png" alt="smile" />',
':-)' => '<img src="http://blog.sachinkraj.com/images/smilies/smile.png" alt="smile" />',
':D' => '<img src="http://blog.sachinkraj.com/images/smilies/laugh.png" alt="laugh" />',
':d' => '<img src="http://blog.sachinkraj.com/images/smilies/laugh.png" alt="laugh" />',
';)' => '<img src="http://blog.sachinkraj.com/images/smilies/wink.png" alt="wink" />',
':P' => '<img src="http://blog.sachinkraj.com/images/smilies/tounge.png" alt="tounge" />',
':-P' => '<img src="http://blog.sachinkraj.com/images/smilies/tounge.png" alt="tounge" />',
':-p' => '<img src="http://blog.sachinkraj.com/images/smilies/tounge.png" alt="tounge" />',
':p' => '<img src="http://blog.sachinkraj.com/images/smilies/tounge.png" alt="tounge" />',
':(' => '<img src="http://blog.sachinkraj.com/images/smilies/sad.png" alt="sad face" />',
':o' => '<img src="http://blog.sachinkraj.com/images/smilies/shock.png" alt="shock" />',
':O' => '<img src="http://blog.sachinkraj.com/images/smilies/shock.png" alt="shock" />',
':0' => '<img src="http://blog.sachinkraj.com/images/smilies/shock.png" alt="shock" />',
':|' => '<img src="http://blog.sachinkraj.com/images/smilies/straight.png" alt="straight face" />',
':-|' => '<img src="http://blog.sachinkraj.com/images/smilies/straight.png" alt="straight face" />'
);
return (strtr($text, $codesToConvert));
}
Here is how the above code works:
$comment = 'This is the example comment with few smilies code we use normally. Like these: :) :D :P :p :O :-| . Its funny and cute. Isnt it? :)';
echo '<strong>Text with smiley codes:</strong>' . $comment ;
echo '<strong>Text with smiley images:</strong>' . addSmilies($comment);
Here is part of the code that assigns the smarty variable which are later used to display the reviews (comments).
$averageRating = am_getrating($got_gameid);
$reviews = am_queries($db, "SELECT * FROM AMCMS_reviews WHERE gameid=$got_gameid AND approved=1;");
$countreviews = am_countrecords($db, "SELECT * FROM AMCMS_reviews WHERE gameid=$got_gameid AND approved=1;");
$smarty->assign('sitetitle',$sitetitle);
$smarty->assign('metadesc',$metadesc);
$smarty->assign('metakeywords',$metakeywords);
$smarty->assign('insertGame',$insertGame);
$smarty->assign('headload',$headload);
$smarty->assign('bodyload',$bodyload);
$smarty->assign('gameAvgRating', $averageRating);
$smarty->assign('echoComment', $echoComment);
$smarty->assign('gameId', $gameres[0][0]);
$smarty->assign('gameName', $gameres[0][1]);
$smarty->assign('gameDescription', $gameres[0][2]);
$smarty->assign('gameOriginalWidth', $originalwidth);
$smarty->assign('gameOriginalHeight', $originalheight);
$smarty->assign('gameFilename', $gameres[0][6]);
$smarty->assign('gameCategory', $gameres[0][7]);
$smarty->assign('gamePlayCount', $gameres[0][8]);
$smarty->assign('gameExtension', strtolower($gameres[0][10]));
$smarty->assign('gameReviews', $reviews);
$smarty->assign('gameCountReviews', $countreviews);
$smarty->assign('gameHighScoreList', am_highscore($gameres[0][0], 'high', 10, 'list', false));
$smarty->assign('gameRecommendedList', am_listnewgames('list', 8, $gameres[0][7], false));
$smarty->assign('gameCode', html_entity_decode($gameres[0][15]));
Here is the code that shows the comments
{$echoComment}
</div></div>
<p />
<div class="reviews">
<h2 class="title"><center>{$gameCountReviews} reviews for {$gameName}</center></h2>
<center>
{foreach from=$gameReviews item=individualReview}
<div class="individualreview">Review by <i>{$individualReview.2}</i><p />
<div class="reviewtext">{$individualReview.3}</div>
</div><br /><p />
{/foreach}
I have been trying to fix this all day and it just wont show the comments, i tried to assign the script to a smarty variable but then how would i use it as the script says ? addSmilies($comment);
I tried few other scripts and tried to include it in the .tpl file but that didnt work, i tried all kinds of ways to make the addSmilies({$individualReview.3}) work by adding what not in there but it just wont work.
For the last few hours i have been looking in the smarty manual but i cant see anything even close to this
I am sorry for all the code and i am really new to php and smarty so i really need some help.
Please somebody help me

The easiest way would be to add them before sending them to the template.
$reviews = am_queries($db, "SELECT * FROM AMCMS_reviews WHERE gameid=$got_gameid AND approved=1;");
foreach ( $reviews as $rev )
{
$rev[ 3 ] = addSmilies( $rev[ 3 ] );
}
$smarty->assign('gameReviews', $reviews);
If at first you don't succeed, you're not Chuck Norris.

I tried what you suggested but the script crashed so i changed it to this script:
function smiley($text)
{
$path = "./smiley";
$width = '24';
$height = '24';
$arr[":))"] = "d.png";
$arr[":(("] = "cry.png";
$arr[";)"] = "wink.png";
$arr[":s"] = "s.png";
$arr[":@"] = "angry.png";
$arr[":)"] = "happy.png";
$arr[":("] = "sad.png";
$arr[":o"] = "o.png";
$arr[":x"] = "love.png";
$arr["b-)"] = "b.png";
$arr[":d"] = "d.png";
$arr[":p"] = "p.png";
$arr["o)"] = "angel.png";
$arr[":-b"] = "nerd.png";
$arr[":*"] = "kiss.png";
$arr["x("] = "angry.png";
$code_arr = array_keys($arr);
foreach($code_arr as $code)
$text = str_ireplace($code, "<img width = '" . $width . "' height = '" . $height . "' src='$path/" . $arr[$code] . "'>" , $text);
return $text;
}
After putting your code in the file nothing changed all smilies just show as text
$reviews = am_queries($db, "SELECT * FROM AMCMS_reviews WHERE gameid=$got_gameid AND approved=1;");
foreach ( $reviews as $rev )
{
$rev[ 3 ] = smiley( $rev[ 3 ] );
}
Any other suggestions ?
Any way to do the same foreach in smarty ?

My bad.
I would use your previous addSmilies method (strtr). It is alot more efficient.
I was a bit of a clot and forgot that the value $rev from the foreach wasn't a pointer to $reviews   . A normal for loop will work.
$reviews = am_queries($db, "SELECT * FROM AMCMS_reviews WHERE gameid=$got_gameid AND approved=1;");
for ( $i = 0; $i < count( $reviews ); $i++ )
{
$reviews[ $i ][ 3 ] = addSmilies( $reviews[ $i ][ 3 ] );
}

There is no point, as it shouldn't technically be in the template. And it would make the template messy, which is never a good thing.

This must have all the basics of the game completed and functioning. This means that the game must generate the two dice values and display an image for each individual dice. Set the correct conditions for the first throw to determine a win or a loss or the setting of a point. If the point is set the play must continue with consecutive throws until the point is matched or a 7 is thrown and a win or a loss is determined.

How to extract Numeric values from String
plz help
|
|
|
|
|
not sure if you mean you have a string with a number in it and need to pull just the string or if you have a number returned as a string.
but for the first you can separate the string using explode and then looping through the returned array and checking for is_numeric returning true and extracting that.
the second should be able to be used directly
$a = '1';
$echo 1 + $a;
but if there is a issue with it, you can use an explicit cast like in C (int)$a for example.

In the PHP documentation of Strings[^] there is a little snippet just over a third of the way down called "String conversion to numbers", which may help you.
Other than that, you could always go through the string char by char

I know this is a few days old but I thought I'd mention some new functionality in PHP. PHP Filters. Specifically:
<?php
$value01 = '123abc456def';
echo filter_var($value01, FILTER_SANITIZE_NUMBER_INT);
?>
Will Output:
123456

That's very useful. Bookmarked this for future reference, just in case.

I'm about to start a pet web project and I have chosen to use Python for it.
But, I'm stuck at the beginning, because I have a dilemma about the framework to use.
From what I saw, there are two frameworks I like, Django and web2py.
Anyone here has any real experience with these two, or have a good reason why one it better that the other?
[edit]
What's the matter? Nobody uses Django, nor web2py, nobody uses python, or nobody visits this forum?

I did that, more that once.
There are a lot of people arguing that Django is the better choice, and a lot arguing the opposite.
Nevertheless...I chose Django. So far, I like it.

Sorry for seeing the post soo late.
I don't know a single person using web2py in production so that may make it a tad scary to get started. I use Django and web.py professionally and it really is a question about your needs.
Personally, it took me some time to get comfortable with Django but now that I am I tend to prefer it.

I've made my choice, already
I decided to go with Django, and am quite happy with the decision, by now.
One of the biggest pros was the community around Django, something web2py can't really compete with.
After all, for learning a new framework, community tends to be quite important.

If you have questions about web2py and want more information about people running it on production, I would suggest you join (even if temporarily) the web2py google group. There are more than 1500 members and a lot of people using it in production who will be happy to share their opinions with you. You will find a very active community. The web2py community is younger therefore not as big as Django's.
As an axample, the PyCon 2010 registration site runs web2py in production. It used to run on Django but moved to web2py two years ago. http://us.pycon.org/2010/register

Hi,
I am making a game, where I want to move the character with mouse click. It is a tile based game with isometric view.
# mouse move
if e.type==pygame.MOUSEBUTTONDOWN:
#movehero
movehero=True
if e.type==pygame.MOUSEBUTTONUP:
movehero=False
if movehero==True:
# the movement code
Can anyone tell me how to get the position of mouse click so that the character will move there itself?
Kindly help
Thanks

Scenario: a GUI allows to upload a .jpg and display on the page.
I successfully got the data of .jpg and uploaded into Oracle, the problem is the data row of this .jpg has length=0 and couldn't display the picture.
How can I check to see if the query(use to insert into database) bears the correct value before inserting? if yes, what might be the problem that oracle database doesn't have correct value?
Have spent a long time but couldn't figure out the issue, please give advice..thanks..
