[SOLVED] save php generated images

[kharddie]

hey guys,

I have this php code that receives variables form flash to create image which works fine.

what i want to do is save that image after its been created on my server instead of showing it as  is in the code below.

 

how do i go abut that to save it in this folder -----flashimages/

 

thanks guys.

 

 

 

 

 

<?php

 

error_reporting(0);

/**

* Get the width and height of the destination image

* from the POST variables and convert them into

* integer values

*/

$w = (int)$_POST['width'];

$h = (int)$_POST['height'];

 

// create the image with desired width and height

 

$img = imagecreatetruecolor($w, $h);

 

// now fill the image with blank color

// do you remember i wont pass the 0xFFFFFF pixels

// from flash?

imagefill($img, 0, 0, 0xFFFFFF);

 

$rows = 0;

$cols = 0;

 

// now process every POST variable which

// contains a pixel color

for($rows = 0; $rows < $h; $rows++){

// convert the string into an array of n elements

$c_row = explode(",", $_POST['px' . $rows]);

for($cols = 0; $cols < $w; $cols++){

// get the single pixel color value

$value = $c_row[$cols];

// if value is not empty (empty values are the blank pixels)

if($value != ""){

// get the hexadecimal string (must be 6 chars length)

// so add the missing chars if needed

$hex = $value;

while(strlen($hex) < 6){

$hex = "0" . $hex;

}

// convert value from HEX to RGB

$r = hexdec(substr($hex, 0, 2));

$g = hexdec(substr($hex, 2, 2));

$b = hexdec(substr($hex, 4, 2));

// allocate the new color

// N.B. teorically if a color was already allocated

// we dont need to allocate another time

// but this is only an example

$test = imagecolorallocate($img, $r, $g, $b);

// and paste that color into the image

// at the correct position

imagesetpixel($img, $cols, $rows, $test);

}

}

}

 

// print out the correct header to the browser

header("Content-type:image/jpeg");

// display the image

imagejpeg($img, "", 90);

?>

thanx for that

i have replaced the last bit of the code with this

 

imagejpeg($im, 'proofing_files_edited_by_clients/mynewimage.jpg', 90);

 

but still no luck

and yes the folder --proofing_files_edited_by_clients--has read write permission

 

<?php

 

error_reporting(0);

/**

* Get the width and height of the destination image

* from the POST variables and convert them into

* integer values

*/

$w = (int)$_POST['width'];

$h = (int)$_POST['height'];

 

// create the image with desired width and height

 

$img = imagecreatetruecolor($w, $h);

 

// now fill the image with blank color

// do you remember i wont pass the 0xFFFFFF pixels

// from flash?

imagefill($img, 0, 0, 0xFFFFFF);

 

$rows = 0;

$cols = 0;

 

// now process every POST variable which

// contains a pixel color

for($rows = 0; $rows < $h; $rows++){

// convert the string into an array of n elements

$c_row = explode(",", $_POST['px' . $rows]);

for($cols = 0; $cols < $w; $cols++){

// get the single pixel color value

$value = $c_row[$cols];

// if value is not empty (empty values are the blank pixels)

if($value != ""){

// get the hexadecimal string (must be 6 chars length)

// so add the missing chars if needed

$hex = $value;

while(strlen($hex) < 6){

$hex = "0" . $hex;

}

// convert value from HEX to RGB

$r = hexdec(substr($hex, 0, 2));

$g = hexdec(substr($hex, 2, 2));

$b = hexdec(substr($hex, 4, 2));

// allocate the new color

// N.B. teorically if a color was already allocated

// we dont need to allocate another time

// but this is only an example

$test = imagecolorallocate($img, $r, $g, $b);

// and paste that color into the image

// at the correct position

imagesetpixel($img, $cols, $rows, $test);

}

}

}

 

 

//save image

imagejpeg($im, 'proofing_files_edited_by_clients/mynewimage.jpg', 90);

?>

1. welcome to the forum

2. please use code tags (the [code.][/code.]) without the dot

3. GuiltyGear, is correct, check the path

try:

 

imagejpeg($img, 'proofing_files_edited_by_clients/mynewimage.jpg', 90);

 

as your image recourse is $img, not $im
