[SOLVED] word wrapping an image string (imagettftext) bug

[yekis]

i am displaying an string on top an image...this is my original code ..the original code works...however,

 

  when i want to word wrap the string....the string still displays only one line of text...it doesn't go/break to the next line....

 

  ORIGINAL CODE:

 

          //displays string

 

          imagettftext($im, 18, 0, 10, 90, $white, $font, $description);

 

 

 

  REVISED CODE with WORDWRAPPING (can't find the bug)..tnx

     

      //displays string and defines its position

 

      imagettftext($im, 18, 0, 10, 90, $white, $font, $description);

      $text = $imagettftext;

 

      //wraps string???

 

        $newtext = $newtext = wordwrap($text, 20, "<br />\n");

 

      echo $newtext;  ## is this needed??

 

------------------------------

You want to use

wordwrap($text, 20, "<br />\n");

 

what you are currently doing is adding a new line (\n) in the source but this won't

affect the browser display.

 

EDIT:

 

Code will look something like this

//$text = the text you want outputted by imagettftext()
$new_text = wordwrap($text, 20, "<br />\n");
imagettftext($im, 18, 0, 10, 90, $white, $font, $new_text);

this is now my revised code...but what happens no string is displayed once i type some text on the description field when i press the submit button.....what are the errors on my code? tnx a lot! i'm a newbie to php and i'm beginnign to love this site..

 

REVISED CODE

--------------------

$text = $_GET['description']; 
  $new_text = wordwrap($text, 20, "<br />\n");
  imagettftext($im, 18, 0, 10, 90, $white, $font, $new_text);

---------------------------

 

**should i still use the echo $new_text syntax?...coz i removed it from the code...tnx

Looking at the comments on this function reference at php.net it is pretty involved to get multi-line text working with imagettftext().

 

This is the easiest user posted solution

function imagettfmultilinetext($image, $size, $angle, $x, $y, $color, $fontfile,  $text, $spacing=1)
{
$lines=explode("\n",$text);
for($i=0; $i< count($lines); $i++)
    {
    $newY=$y+($i * $size * $spacing);
    imagettftext($image, $size, $angle, $x, $newY, $color, $fontfile,  $lines[$i], $spacing);
    }
return null;
}

if(isset($_GET['description'])){
  $text = $_GET['description'];
  $new_text = wordwrap($text, 20, '\n');
  imagettfmultilinetext($im, 18, 0, 10, 90, $white, $font,  $new_text);
}

 

I was wrong to suggest

wordwrap($text, 20, "<br />\n")

, I forgot this was overlaying a string on an image so HTML formatting doesn't matter.
