I would advise learning C++ or C# as a lanaguage as it is very common in alot of computers industrys.

February 14, 2009

I think the main problem is that these tutorials on OOP all teach you how to use it but none teach you where and why to use it, btw does anyone have a tutorial that does?

Hello

We am looking for someone to work on our our site American Gangsters.

We currently have made a design but would like to have a new design created using CSS and have it more flexible, all we need is a template page with comments, although more work maybe required later on.

The page needs to be very dependent on CSS so we can implement future ideas.

Please PM me with quotes or for more information.

This is the site - http://www.americangangsters.org/

Thanks,

AG Team

Have you even tried this yourself?

Show us how far you got and where you got stuck and we can help

Try

<?php
$src_image = imagecreatefromjpeg($stored_image);

$new_thumb_width = 85;

$new_thumb_height = 64; 

list($width, $height) = getimagesize($src);
    
$thumb_w = $new_thumb_width;

$thumb_h = $new_thumb_height;    

$thumb = imagecreatetruecolor($thumb_w, $thumb_h);

imagecopyresampled($thumb, $src_image,0,0,0,0,$thumb_w, $thumb_h, $width, $height);

imagejpeg($thumb);

imagedestroy($src_image);

imagedestroy($thumb);

echo $thumb_w;

echo "<br/>";

echo $thumb_h;
?>

Not with PHP alone, try looking at ajax, or maybe a css based alternative

Ok still got the problem, but here is a working version using OOP

I have already seen that lol, i suppose that you was trying to say that yes it is because of recreating the file, and with that function below glancing over it it will just find out if the file is an animation and tell you how many frames and not a way to recreate them.

Ok i have made this half-way solution, just to make sure the code works.

But now i have a problem that animated files don't play animations, i assume this is due to the image being recreated?

February 5, 2009

Yeah, i dunno, i will try again on Saturday or something when i am not tired.

Would of saved me a lot of time if my host didn't just say 500 internal error :s

February 5, 2009

Hmm i was hoping to keep it simpler than that, i might just change it to OOP and that will make it easier/simpler for me

February 5, 2009

Yep that kills the page, which it shouldn't, because the image link is fine

Edit; according to my error reporting $avatars and $avatar_count are not defined :s

Surely i don't need to pass them to the function via an argument?

February 5, 2009

You can use a db to store the houses or whatever and then check for a column to see if it is sold or not and display the unsold ones.

February 5, 2009

No, $new_width echos 0

$width,$height and $new_height don't print anything , i assume they are not being set.

The image is not being saved to the folder.

February 5, 2009

Yes that is JS, please ask in the JS section

February 5, 2009

Just make a link that goes to the page

e.g.

<a href="upload.php">Upload another image</a>

or do you mean using JS?

February 5, 2009

Look into $_GET

February 5, 2009

Ok, so i have decided to rewrite my random avatar code and has not worked at all., lol.

So here is my problem, when i first ran the code it caused a 500 internal server error, then i found that a function named random_check was causing this and further debugging showed that $avatar_count and $_SESSION['num']; are not defined.

So i have tried to fix it and cannot find why its not working, any help is appreciated.

change

mail ("$email", 'Statement for', "Thank You!", $headers);

to

if( mail ("$email", 'Statement for', "Thank You!", $headers))

echo "Sent";

else

echo "failed";

February 3, 2009

Ok have a look at the php manual about headers, and also try removing the function on the email address (to).

February 3, 2009

function returning()
{
   return "Code";
}

function echoing()
{
  echo "Code";
}

echo echoing()." <br> ".returning();

February 3, 2009

Try using a real from address

February 3, 2009

You can use return (in the function)

February 3, 2009

At the end of the IF?

February 3, 2009

Try

$content .= "<div id=\"full_content\">

Shopping Cart<br />

".showCart()."

</div>";

Or the best way would be to remake the function
