How to correctly use of imagettftext?

Question

I am making a form which the user is filling to create a mail signature:

generatarjeta.php

if(isset($_GET["suc"]) && $_GET["suc"] !="")
{ $code="";
  foreach($_GET as $key => $value){
    $code.= $key . "=" . $value . "&";
  }
  $code = rtrim($code,"&");
  ?>
  <img src="imagem.php?<?php echo $code;?>">
  <script>window.history.pushState("", "", '/generatarjeta.php');</script>
  <?php exit();
}

<form method="get">
      <table>
        <tr><td><label>Sucursal</label></td><td><select name="suc">
          <option value="">Seleccione...</option>
          <?php
          $con_sucursal = mssql_query("select * from localitos where local NOT IN (3,5, 7,12, 13, 14,15,16,17,19, 20, 21, 22,23,24,25,26,27)");
          while ($res_sucursal = mssql_fetch_array($con_sucursal))
          {
            echo "<option value='$res_sucursal[0]'>$res_sucursal[1]</option>";
          }?>
        </select></td></tr>
        <tr><td><label>Nombre del Trabajador: </label></td><td><input type="text" name="nombre" required="" onkeypress="return textonly(event);"/></td></tr>
        <tr><td><label>Puesto: </label></td><td><input type="text" name="puesto" required="" onkeypress="return textonly(event);"/></td></tr>
        <tr><td><label>Telefono: </label></td><td><input type="text" name="tel" required="" onkeypress='return solonums(event)'/>&nbsp;<label>Extension: </label><input type="text" name="ext" onkeypress='return solonums(event)'/></td></tr>
        <tr><td><label>correo: </label></td><td><input type="text" name="mail" placeholder="nombre.apellido"/></td></tr>
        <tr><td><input type="submit" name="submit" value="Generar"/></td><td><input type="reset"/></td></tr>
      </table>
    </form>

imagem.php

//Carregar imagem
$rImg = ImageCreateFromJPEG("the_firma.jpg");
//Definir cor
$cor = imagecolorallocate($rImg, 226, 41, 34);
$cor2 = imagecolorallocate($rImg, 60, 60, 59);

$tel = "$_GET[tel] Ext. $_GET[ext]";
$correo = "$_GET[mail]@mail.x";
//Escrever nome
imagettftext($rImg,14,0,850,60,$cor,'Open Sans',$_GET["nombre"]);
//imagestring($rImg,5,850,60,urldecode($_GET["nombre"]),$cor);
//imagestring($rImg,5,850,80,urldecode($_GET["puesto"]),$cor2);
//imagestring($rImg,5,800,120,urldecode($tel),$cor2);
//imagestring($rImg,5,800,140,urldecode($correo),$cor2);
//Header e output
header('Content-type: image/jpeg');
imagejpeg($rImg,NULL,100);

My issue is, when I use imagestring, everything works fine, but I need to use Open Sans ttf so I tried to use imagettftext, but it "echoes" an empty result or error when loading img src and also when testing file separately it doesnt show any error.

Any suggestions?

UPDATE:

$tel = "$_GET[tel] Ext. $_GET[ext]";
$correo = "$_GET[mail]@mail.mx";
$puesto = strtoupper($_GET["puesto"]);


imagettftext($rImg, 14, 0, 780,60, $cor, 'OpenSans-Bold.ttf', $_GET['nombre']); (WORKS)
imagettftext($rImg, 8, 0, 780,80, $cor2, 'OpenSans-Regular.ttf', $puesto); (WORKS)
imagettftext($rImg,9,780,135,$cor2, 'OpenSans-Regular.ttf',urldecode($_GET["tel"])); (CRASHES)
imagettftext($rImg,9,780,172,$cor2,'OpenSans-Regular.ttf',$correo);(CRASHES)
imagettftext($rImg,8,780,209,$cor2,'OpenSans-Regular.ttf',$_GET["direccion"]);(CRASHES)
imagettftext($rImg,8,780,223,$cor2,'OpenSans-Regular.ttf',$_GET["dir2"]);(CRASHES)

It looks correct to me. Are you sure your variables are correct? Have you tried to var_dump(urldecode($correo));? — Andreas, Jul 06 '17 at 19:40
$correo does work correctly with imagestring, not with imagettftext — Neobugu, Jul 06 '17 at 22:52

As documented, the $fontfile parameter needs a path to the font file, not its display name:

The path to the TrueType font you wish to use.

The simplest solution is to put the .ttf file (opensans.ttf?) in the same folder as your script and then change your function call like so:

imagettftext($rImg, 14, 0, 850, 60, $cor, 'opensans.ttf', $_GET['nombre']);

Then the name of the ttf should be open_sans.ttf? – Neobugu Jul 07 '17 at 15:00

I don't know what the name of the file you have is. You'll need to check this yourself. On my system the regular font is `OpenSans-Regular.ttf`. – timclutton Jul 07 '17 at 15:16
Well it does work as you said, but when I send a parameter with numbers it crashes maybe is my sintax I'll edit with part of your code – Neobugu Jul 07 '17 at 15:26
Is there an error message when it crashes? (Check the PHP errors log if you don't have `display_errors` enabled.) – timclutton Jul 07 '17 at 15:43
Comment out the 'header' line so that you can see any error messages. – timclutton Jul 07 '17 at 15:49

Done, I was missing a parameter P: ty – Neobugu Jul 07 '17 at 16:50
