Hi guys, i have problem with php. I want to make website which create baner for user when they fill out the form. This is banner (without text and image): http://misterijeforum.com/nik/images/medium.png

 

I made form also: http://misterijeforum.com/nik/small.html

 

But i got problems with php script. I'm not php programmer, but i created "something"

 

<?php
header('Content-Type: image/png');

$im = ImageCreateFromPng("images/medium.png"); 

$black = imagecolorallocate($im, 0, 0, 0);
$ime = "$fullname";
$interests = "%interests";
$school = "%school";
$fb = "%facebook";
$msn = "%msn";
$mail = "%mail";
$start_x = 1;
$start_y = 1;
Imagettftext($im, 12, 0, $start_x, $start_y, $black, 'verdana.ttf', $ime);

Imagepng($im);

ImageDestroy($im);


?>

I made just for full name, but i don't know how to storage that new image in folder "images" and show image to user. And is this code good ?

This forum (PHP Coding Help) is for people to get help with code they have written. There is a separate forum here for Freelancing if you want someone to write the code for you.

OK, I was in a good mood. A quick google search directed me to a tutorial on this very site (http://www.phpfreaks.com/tutorial/php-add-text-to-image) which I used to create the following:

 

 

<?php

error_reporting(E_ALL);

//Set values based upon form POST data
$fullname = "Ricardo Montobaln";
$location = "Denver, Colorado";
$school = "School of Hard Knocks";
$facebook = "www.facebook.com/myprofile";
$email = "myname@domain.com";

//Path to image
$imageName = 'images/medium.png';

//Font face and size
$font  = 'verdana.ttf';
$fontSize = 10;
$spacing = 22; //horizontal spacing between lines

//Create image object
$image = ImageCreateFromPng($imageName );

//Pick color for the text
$fontColor = imagecolorallocate($image, 255, 255, 255);

//Set start x & y positions
$x = 75;
$y = 16;

//Add name text
imagettftext($image, $fontSize, 0, $x, $y, $fontColor, $font, $fullname);
//Move y position down and add location text
imagettftext($image, $fontSize, 0, $x, $y+=$spacing, $fontColor, $font, $location);
//Move y position down and add school text
imagettftext($image, $fontSize, 0, $x, $y+=$spacing, $fontColor, $font, $school);
//Move y position down and add facebook text
imagettftext($image, $fontSize, 0, $x, $y+=$spacing, $fontColor, $font, $facebook);
//Move y position down and add email text
imagettftext($image, $fontSize, 0, $x, $y+=$spacing, $fontColor, $font, $email);

header('Content-Type: image/png');

//Output image to the browser
imagepng($image);

//Delete the image resource
imagedestroy($image);

?>

 

Note: You set the position of the first line using the values for $x and $y. Then the  $spacing variable is used to move down to the next line after you place a line of text. That is done by using "$y+=$spacing" inside the function call for imagettftext(). That will increment $y by the value of $spacing.

 

EDIT: you may want to think abut reducing the font size. Otherwise values that are a little long will go past the right edge of the black area. Or you could make the image wider.

It's working, thank you so much. It's work perfectly on localhost, but online is problem with font: "Could not find/open font"

You should pick a font that will be available on your server, such as Arial. If you are developing on a Windows machine and your app is running on a Linux box you will be limited on the fonts available.

You also need to make sure the $font variable contains the correct path to the font file
