Hi

I want users to be able to create an image from either an image template on my site (labelled $im) or by entering in a url.I think i've worked it out, but my php is not very good so can you tell me where i'm going wrong with it please?

I realised that the

PHP Code:

$im = imagecreatefromjpeg($im) 


doesn't have to point to a variable, it can also point to a url i.e

PHP Code:

$im = imagecreatefromjpeg(http://www.address.com/image.jpeg) 


YEY- This works, however when i try adding a tick box to the html form that the user checks when they want to specify an address i get the url coming up instead of the image.

This is the code that i have put in the php file...

PHP Code:

if($link== 'y'){
$im = imagecreatefromjpeg($useraddress);
}else{
$im = imagecreatefromjpeg($im);
} 


The checkbox is called link and the textbox for the address is called useraddress.

If you want to see for yourself what its doing go to www.gamesigs.co.uk/test.php

Cheers and i hope to hear from you soon.

1. that page doesn't work ( the link you gaved )
2. you must have register_globals on ... to use $link instead of $_POST['link']
or are you converting globals to local variables you're self ?
3. try puting

PHP Code:

$im =  @imagecreatefromjpeg($useraddress); /* Attempt to open  */
   if (!$im) echo "Can't open image [ $useraddress ]"; 


sorry that didnt work any other ideas. p.s try the link again.

can you post more code here ... to make a more acurete ideea

Ye sure...

I now am having even worse problems i cant get the image to be created from the url.

Here is my code and to summarise all i want to do is for a person to submit a url on a form that it sends to this page (my register globals are off) and puts the text they specify onto the image from the url. Thanks a lot.

PHP Code:

<?php

header("Content-type: image/jpeg");

$name = stripslashes($_GET['name']);

$line2 = stripslashes($_GET['line2']);

$size = stripslashes($_GET['size']);

$centre = stripslashes($_GET['centre']);

$font = 'images/sig_maker/fonts/'.stripslashes($_GET['font']).'.ttf';

$fontcolor['r'] = stripslashes($_GET['color_r']); // font color - RED

$fontcolor['g'] = stripslashes($_GET['color_g']); // font color - GREEN

$fontcolor['b'] = stripslashes($_GET['color_b']); // font color - BLUE

$lines = stripslashes($_GET['lines']);

function arrow($im, $x1, $y1, $x2, $y2, $alength, $awidth, $color){
///
}

if(is_numeric($_GET['color']) && $_GET['color'] >= '1' && $_GET['color'] <= '63')
{
    $bgpic = 'images/sig_maker/' . $_GET['color'] . '.jpeg';
}


$im = imagecreatefromjpeg($bgpic);


//Calculate, the centre:

for(;;){

list($image_width, $image_height) = getimagesize($bgpic);
list($left_x, , $right_x) = imagettfbbox($size, 0, $font, $name);
$text_width = $right_x - $left_x;
if($image_width > $text_width+5){

break;

}

$size = $size - .5;
if($size == 1){
die('Script not responding to decreasing font size, in other words: try using less letters.');
}
}
$hpadding = ($image_width - $text_width)/2;
$vpadding = ($image_height/2);

$textcolor = imagecolorresolve($im, $fontcolor['r'], $fontcolor['g'], $fontcolor['b']);
if($centre== 'y'){

imagettftext($im, $size, 0, $hpadding,$vpadding, $textcolor, $font, $name);
imagettftext($im, $size -10,0,$hpadding,$vpadding+$size,$textcolor,$font,$line2);

}else{

imagettftext($im, $size, $angle, $x, $y, $textcolor, $font, $name);
imagettftext($im,$size - 10,$angle,$x,$y+$size,$textcolor,$font,$line2);

}

imagegif($im);
imagedestroy($im);
?>

ok i've just realised my host suddenly and without warning decided to disable fopen so i think this is why it isnt working, Only local files can be opened. Is there any way to get around this?

They probably disabled cURL

do you have php.ini in your root folder.

try this:
create php.ini in your root folder
add this line.
allow_url_fopen = on
