imagecreatepng()

ok ive created a simple script, and its easier for me to show you then explain it

Code:

<?php

header('Content-type: image/png');
$im = imagecreatefrompng ("blocks_01.png");
$font = 'Hooge_0853.TTF';
$size[1] = 8;
imagettftext($im, $size[1], 0, 15, 15, $color, $font, $title);
imagepng($im);
imagedestroy($im);

?>

View it here http://www.extreme-hq.com/work/themes/eX-Studio/blocks_01.php

What i want to do is use this as an image in my blocks and have it display the title of the block, so i coded my block like so

Code:

<table id="Table_01" width="210" height="201" border="0" cellpadding="0" cellspacing="0">
<tr>
<td>
<div align="center">
<div valign="top"><img src="http://www.extreme-hq.com/work/themes/eX-Studio/blocks_01.php"></img></div>
</div></td>
</tr>
<tr>
<td background="themes/eX-Studio/images/blocks_02.gif" width="210" height="168">
<table width="95%" border="0" align="center">
<tr>
<td>$content</td>
</tr>
</table></td>
</tr>
</table>

and as you can see from here http://www.extreme-hq.com/work/ the image is displayed, but the title isnt, and thats obviousally because my script dosnt know what $title is. Do i have to place my code is a special place? Do i have to have me code connect to the nuke database? or, How do i include this code in my block for it to work?

thanks.

Me thinks all you need to do is place $title in front of the closing img tag.

In the future, you might wish to move all the decorative code into the style.css file.....

indeed that would work, but that would negate the whole point of using the imagecreatefrompng() function

<?php

header('Content-type: image/png');
$im = imagecreatefrompng ("blocks_01.png");
$font = 'Hooge_0853.TTF';
$size[1] = 8;
// Your line
// imagettftext($im, $size[1], 0, 15, 15, $color, $font, $title);

// You can write the title into the image, passing it by GET
imagettftext($im, $size[1], 0, 15, 15, $color, $font, $_GET['title']);
imagepng($im);
imagedestroy($im);

?>

So,

1) You can try to pass "title" by GET.
2) You must call the blocks_01.php from an internal phpnuke file, so you can retrieve the "title" variable by add:

global $title;

before the header method.

perfect!
i changed my block to

Code:

<table id="Table_01" width="165" border="0" cellpadding="0" cellspacing="0">
<tr>

<td background="http://www.extreme-hq.com/work/themes/eX-Studio/blocks_01.php?title=$title" width="165" height="21">
<div align="center"><strong></strong></div></td>
</tr>
<tr>

<td background="themes/eX-Studio/images/blocks_02.gif" width="165"><table width="95%" border="0" align="center">
<tr>
<td>$content </td>
</tr>
</table> </td>
</tr>
<tr>
   <td>
      <img src="themes/eX-Studio/images/blocks_03.gif" width="165" height="26" alt=""></td>
</tr>
</table>

and blocks_01.php to

Code:

<?php
header('Content-type: image/png');
$im = imagecreatefrompng ("blocks_01.png");
$font = 'Hooge_0853.TTF';
$size[1] = 8;
$title = $_GET["title"];
imagettftext($im, $size[1], 0, 15, 15, $color, $font, $title);
imagepng($im);
imagedestroy($im);
?>

and it works like a charm
