[SOLVED] New problem with GD and merge two images

[Isterklister]

Hello again,

I have now picked up some code to merge two pictures (with transparency).

^<?php

^{$flag = $_GET['flag'];}

^{/* Attempt to overlay transparent and semi-transparent images */}

^{$width = 800;}

^{$height = 600;}

^{$dst_width = 800;}

^{$dst_height = 600;}

 

^{$bottom_image = imagecreatefrompng("flag-back.png");}

^{$top_image = imagecreatefrompng('$flag');}

^{imagesavealpha($top_image, false);}

^{imagealphablending($top_image, false);}

^{imagecopy($bottom_image, $top_image, 0, 0, 0, 0, $width, $height);}

^{header('Content-type: image/png');}

^{$erer = 232;}

^{imagepng($bottom_image);}

^{imageDestroy($bottom_image);}

^?>

 

I call the sript from another file:

^{echo "<img src='merge_flag_logo.php?flag=$flag_t[flag]>";}

 

The script works fine if I instead of $_GET... just write a picture name instead of $flag.

How can I get the image name with GET and use it in the script?

Thanks

i would say firstly,

 

$top_image = imagecreatefrompng('$flag');

 

you need quotes on that, not 's... 's kill variables... it is looking for the file by the name of '$flag' not for the one specified in $_GET[flag]...

Thanks, I have changed this but it is still not working.

secondly, then i would guess, you have some complications in the file name that is being entered dynamically into the <img> tag... you may want to check for spaces, and whatnot and urlencode/urldecode to avoid that

where is the $_GET var coming from? post that.

[Isterklister]

I call the script via:

^{echo "<img src='merge_flag_logo.php?flag=$flag_t[flag]>";}

where (example) $flag_t[flag] = "flag2.png"

I don't see a closing quote for your src='...'

 

Also, in your script in your OP, did you try echoing out the GET var to make sure it has what you think it has?

[Isterklister]

Thank you! It was the last ' in the scr='...' that was missing.

 

I did test and change so much I missed that little thing.
