Should be simple problems but im a complete newbie

[digi duck]

HI all.
I have a site called www.gamesigs.co.uk which basically lets people choose an image and put text on it for use in forums as signatures. It works fine but there are 2 things that i would like to do to it that i cant seem to work out.

1) I would like a number to display on the pages that shows how many people have created a signature since. I do not want this so it shows every page hit or unique visit becuase this would give the wrong number. I think it would need to be how many times the submit button was clicked or how many times the sigcreated page was visited. As the sig created page is a variable ie. sigcreated?name=nsdcn,font=ncdc etc. I dont know how to do it.

2) After you click the submit button you are taken to the sig created page. Here it shows your signature in the top left corner of a blank page. I would like for the signature to be placed in tables like a proper page so i could put writing around it etc. However becuase of the way the code is written it prevents me doing this.

Please help me solve these 2 issues.

The script for the sigcreated.php page looks like this:

Code: Select all

<?php
header("Content-type: image/jpeg");
$name = stripslashes($_GET['name']);
$size = stripslashes($_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'] <= '47')
{
    $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, $name);
}else{
imagettftext($im, $size, $angle, $x, $y, $textcolor, $font, $name);
}
imagegif($im);
imagedestroy($im);
?>

Thanks so much!

I know of two ways. There may be more.

1. Write the image to a file and then you can just use an <img> tag referencing the file path.
2. A little trickier, due to browser differences, is simply to reference the image.php file as the img src, using GET variables as needed.

[Ryan Fait]

Is that why IE is giving me troubles with the <img> tag with a .php in the src?

[masonbarge]

Yeah. Unfortunately Apache requires the .php suffix, and some browser versions will not recognize a .php file as a graphic no matter what heading you send. A possible workaround is to play with the server-side config files so that, say, .php.jpg is interpreted as an image.

ok right I think i get you know. I have taught myself php so im not great so please explain things in detail and try not to laugh.
Ok heres what ive done (i probably done something really stupid)
I put this img src tag in

Code: Select all

<img src="creation.php"?color=$textcolor&amp;name=$name&amp;centre=$centre&amp;x=$x&amp;y=$y&amp;angle=$angle&amp;font=$font&amp;size=$size&amp;select=255%2C255%2C255&amp;color_r=$fontcolor['r']&amp;color_g=$fontcolor['g']&amp;color_b=$fontcolor['b']&amp;submit=Create+My+Sig%21/>

The variables are the same as i have on the creation page, which looks like:

Code: Select all

<?php
header("Content-type: image/jpeg");
$name = stripslashes($_GET['name']);
$size = stripslashes($_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'] <= '47')
{
    $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, $name);
}else{
imagettftext($im, $size, $angle, $x, $y, $textcolor, $font, $name);
}
imagegif($im);
imagedestroy($im);
?>

and this is the important part of the form that sends them:

Code: Select all

<form method="get" action=http://gamesigs.co.uk/sig_created.php name="form" onsubmit="return checkit(this);">

When i change this form to go to the psge i have with the img src link on it it come up with a broken image. Where am i going wrong?

thanks, thats a good idea i'm going to go attempt it now.

[masonbarge]

For starters, you want to put the entire img src path in quotes.

<img src="creation.php?color=$textcolor& . . . ">
