PHPMailer使用FOR循环添加图像

Question

I have this PHP code:

for($x = 0; $x < count($obrazy); $x++) 
{ 
   $mail->AddEmbeddedImage($obrazy[$x], 'tel'.$x); 
}

the variable "obrazy" is a table storing path (link to the image) e.g. "obraz/zdjecie.png". I need to do this with a loop because the array of obrazy can have a different size each time. The above loop does not work for me, because when I want to show this image in the mail, nothing is displayed.

$iterator = 0;

while ($row = mysqli_fetch_array($rezultat)) 
{      
         $mail->Body = $mail->Body.'//..........

                <img src="cid:tel'.$iterator.'" style="

                    width: 160px;
                    display: block;
                    float: left;

                "/> //..........
           ';

          $iterator++;
}

"// ......" means another part of the code that does not matter to the question being asked. The while loop must be because I extract different data from the database. Everything works only the images do not want to be displayed in the email, even if instead of "$iterator" I enter the number. Links to the image contained in the table are RELIABLE for the PHP file.

Answer 1

Chances are your path or permissions are wrong; Check the return value from addEmbeddedImage:

if (!$mail->AddEmbeddedImage($obrazy[$x], 'tel'.$x)) {
  echo 'Failed to attach '. $obrazy[$x];
}

It's probably a good idea to turn the path into an absolute one, for example by saying something like __DIR__ . '/' . $obrazy[$x] instead of just the relative path.

It may be that your current working directory is not where you think it is. Try doing it like this:

if (!$mail->AddEmbeddedImage(getcwd() . '/' . $obrazy[$x], 'tel'.$x)) {
  echo 'Failed to attach '. getcwd() . '/' . $obrazy[$x];
}

Then it will show you the full path of the files it's failing to find, and you can check whether they are correct.
