Debugging Ajax is a bitch, as it doesn't always throw an error, because technically it works although not the way you want it Frown | :(

I tend to use an "output" box for this that just says what the code is doing step by step on js side and Firefox Error Console. But some errors do still seem to hide.

A function you may know: To read headers sent using PHP you can use:

<?php
var_dump(headers_list());
?>

var_dump prints the results to a browser. In an ajax based system this can be messy.

Although I could have used var_export, I instead used fwrite($fp,file_get_contents("php://input")); so to write the contents of the raw post data before the parser works on filling the $_POST array. Doing it this way allows the server side script of a ajax solution to continue and return some value so your javascript can shutdown gracefully while allowing you to capture the content.

I also use a firefox addon called httpfox so I can observe the communication between my browser and the server.

I don't know much about Visual CPP but the messages look like they are saying that it does not recognise the code in the __asm block. I must say the syntax looks like it needs some sort of preprocessing before going into the compile phase. Have you checked the documentation for the proper format of embedded assembler operations?

Hello everyone, i have a big problem with this $smarty->assign Frown | :(

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()
    @Params      :  1. $text: Text to render.
    @Description :  This functions replaces the basic smiley equavalent codes
                    into smilies and returns back the html code after adding smilies
                    images
    @Returns     :  Returns the converted html string.
 
    NOTE         :  Make sure you provide the image path correctly. Use absolute or relative
                    paths, whatever suits to your script.
    -----------------------------------------------------------------------------*/
    function addSmilies($text) {
        //codes and its relevant smiley image path
        $codesToConvert = array(
                ':)'    =>  '<img src="http://blog.sachinkraj.com/images/smilies/smile.png" alt="smile" />',
                ':-)'   =&gt;  '<img src="http://blog.sachinkraj.com/images/smilies/smile.png" alt="smile" />',
                ':D'    =&gt;  '<img src="http://blog.sachinkraj.com/images/smilies/laugh.png" alt="laugh" />',
                ':d'    =&gt;  '<img src="http://blog.sachinkraj.com/images/smilies/laugh.png" alt="laugh" />',
                ';)'    =&gt;  '<img src="http://blog.sachinkraj.com/images/smilies/wink.png" alt="wink" />',
                ':P'    =&gt;  '<img src="http://blog.sachinkraj.com/images/smilies/tounge.png" alt="tounge" />',
                ':-P'   =&gt;  '<img src="http://blog.sachinkraj.com/images/smilies/tounge.png" alt="tounge" />',

                ':p'    =&gt;  '<img src="http://blog.sachinkraj.com/images/smilies/tounge.png" alt="tounge" />',
                ':('    =&gt;  '<img src="http://blog.sachinkraj.com/images/smilies/sad.png" alt="sad face" />',
                ':o'    =&gt;  '<img src="http://blog.sachinkraj.com/images/smilies/shock.png" alt="shock" />',
                ':O'    =&gt;  '<img src="http://blog.sachinkraj.com/images/smilies/shock.png" alt="shock" />',

               );
        //Replaces smilies codes / add smilies images: IMG html tags and return rendered text
        return (strtr($text, $codesToConvert));
 
    }//END addSmilies()

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? :)';
 
    //prints text as it is, adding just to make it visually good looking
    echo '<strong>Text with smiley codes:</strong>' . $comment ;
 
    //parse text and convert smilies codes into images, lets see
    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); // 5 star rating system
$reviews = am_queries($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;");


// Create template variables:
	$smarty->assign('sitetitle',$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])); // Added in 2.800.

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 Frown | :(

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 Cry | :((

The easiest way would be to add them before sending them to the template.

PHP

$reviews = am_queries($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);

I tried what you suggested but the script crashed so i changed it to this script:

function smiley($text)
{
    // Settings: Change necessary settings here! //

    $path = "./smiley"; // Your Image Folder's Location
    $width = '24';
    $height = '24';

    // Smiley Codes & Image File-name Array - you can change as necessary

    $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";

    // DON'T CHANGE ANYTHING BELOW to avoid malfunction!!!

    $code_arr = array_keys($arr);
    foreach($code_arr as $code)
        $text = str_ireplace($code, "<img width = '" . $width . "' height = '" . $height . "' src='$path/" . $arr[$code] . "'>" , $text);
    // Done! Return text
    return $text;
}

After putting your code in the file nothing changed Frown | :(

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 ?

24-Nov-09 2:30

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 D'Oh! | :doh:

. 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.

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 Poke tongue | ;-P
