Hi again, I have a bar chart, standard 3 verticle bars coloured differently, but now i want to put some text on them, say: Bar A, Bar B, Bar C.
Also this text has to be rotated 90 degrees

So here is the code to make the bars, I guess I need to use:
$red = imagecolorallocate($im, 255, 0, 0);
imagestring($im, 5, 50, 50, "Bar A", $red);
In some kind of loop
so:

$text = array(
imagestring($im, 5, 50, 50, "Bar A", $red);
imagestring($im, 5, 50, 50, "Bar B", $red);
imagestring($im, 5, 50, 50, "Bar C", $red);
);

can anyone help?

Code: [Select]
  for($i=0;$i<$columns;$i++)
    {
        $column_height = ($height / 100) * (( $values[$i] / $maxv) *100);
 
        $x1 = $i*$column_width;
        $y1 = $height-$column_height;
        $x2 = (($i+1)*$column_width)-$padding;
        $y2 = $height;

Code: [Select]
//SQL connect stuff
// This array of values is just here for the example.
 


    //$values = array("5","6","7");
 
// Get the total number of columns we are going to plot
 
    $columns  = count($values);
 
// Get the height and width of the final image
 
    $width = 150;
    $height = 200;
 
// Set the amount of space between each column
 
    $padding = 15;
 
// Get the width of 1 column
 
    $column_width = $width / $columns ;
 
// Generate the image variables





 
    $im        = imagecreate($width,$height);
    $gray      = imagecolorallocate ($im,0xcc,0xcc,0xcc);
    $gray_lite = imagecolorallocate ($im,0xee,0xee,0xee);
    $gray_dark = imagecolorallocate ($im,0x7f,0x7f,0x7f);
    $white     = imagecolorallocate ($im,0xff,0xff,0xff);

    $colours = array(
                  imagecolorallocate ($im,0xff,0x00,0xcc),
                  imagecolorallocate ($im,0xcc,0xff,0x00),
                  imagecolorallocate ($im,0x00,0xcc,0xff)
                   );

 
// Fill in the background of the image
 
    imagefilledrectangle($im,0,0,$width,$height,$white);
 
    $maxv = 0;
 
// Calculate the maximum value we are going to plot
 
    for($i=0;$i<$columns;$i++)$maxv = max($values[$i],$maxv);
 
// Now plot each column
 
    for($i=0;$i<$columns;$i++)
    {
        $column_height = ($height / 100) * (( $values[$i] / $maxv) *100);
 
        $x1 = $i*$column_width;
        $y1 = $height-$column_height;
        $x2 = (($i+1)*$column_width)-$padding;
        $y2 = $height;
 
//        imagefilledrectangle($im,$x1,$y1,$x2,$y2,$gray);
   imagefilledrectangle($im,$x1,$y1,$x2,$y2,$colours[$i]);
 
// This part is just for 3D effect
 
        imageline($im,$x1,$y1,$x1,$y2,$gray_lite);
        imageline($im,$x1,$y2,$x2,$y2,$gray_lite);
        imageline($im,$x2,$y1,$x2,$y2,$gray_dark);
 
    }
 
// Send the PNG header information. Replace for JPEG or GIF or whatever
 
    header ("Content-type: image/png");
    imagepng($im);
imagedestroy($im);

Hi people, I really hope you guys can help me out today. I'm just a newbe at php and i'm having real trouble.

Bassically all I want to do is have a user type in a company name in a html form.

If what the user types in the form matches the company name in my php script i want the user to be sent to another page on my site.

If what the user types in the form doesnt match the company name in my php script i want the user to be sent to a differnt page like an error page for example.

this is my html form:

Code: [Select]
<form id="form1" name="form1" method="post" action="form_test.php">
  <p>company name:
    <input type="text" name="company_name" id="company_name" />
  </p>
  <p>
    <input type="submit" name="button" id="button" value="Submit" />
  </p>
</form>
And this is the php code I'm trying to process the information on:

Code: [Select]
<?php

$comp_name = abc;

if(isset ($_POST["company_name"])){
 if($_POST["company_name"] == $comp_name){

     header("Location: http://www.hotmail.com");
exit();
 }

else{
   header("Location: http://www.yahoo.com");
exit();   
 }
}
?>
The thing is i'm getting this error when i test it:
Warning: Cannot modify header information - headers already sent by (output started at D:\Sites\killerphp.com\form_test.php:10) in D:\Sites\killerphp.com\form_test.php on line 17

Please can some one help me out, i'm sure this is just basic stuff but i just cant get it to work 

Cheers.
