Wie kann ich das Bild in HTML und PHP wiedergeben?

Question

Wie wird das Bild if(isset($post->foto) im Code unten wiedergegeben? Ich versuche mit dem untenstehenden Code, aber ich kann keine Lösung finden. Seine Rückkehr wird folgende Fehler

Parse error: syntax error, unexpected 'userdata' (T_STRING), expecting ',' or ';'.

foreach($postimet as $post){ 
    $firstname = $user->getUserById($post->userid)['first']; 
    $lastname = $user->getUserById($post->userid)['last']; 
    foreach($fotos as $foto){ 
     echo 
     "<div class='po_001'> 
      <div class='po_004'> 
       <img src='timeline/".$foto."' class='po_003'> 
       <div class='po_005'> 
        <a href='profile.php' class='po_002'>$firstname $lastname</a> 
       </div> 
       <div class='po_006'> 
        <span class='p_007'>$post->posttime</span> 
       </div> 
      </div> 
      <div class='po_008'> 
       <p class='po_009'>$post->message</p> 
      </div> 
      <div class='po_010'> 
      if(isset($post->foto)) 
       { 
       <img class='myimage'src='"userdata/".$post->foto->imagename."'> 
       } 
      </div> 
     </div>"; 
    }      
} 

Answer 1

Sie müssen es wie unten tun: -

<?php 
foreach($postimet as $post){ 
    $firstname = $user->getUserById($post->userid)['first']; 
    $lastname = $user->getUserById($post->userid)['last']; 
    foreach($fotos as $foto){?> 
     <div class='po_001'> 
      <div class='po_004'> 
       <img src="timeline/<?php echo $foto;?>" class='po_003'> 
       <div class='po_005'> 
        <a href='profile.php' class='po_002'>$firstname $lastname</a> 
       </div> 
       <div class='po_006'> 
        <span class='p_007'>$post->posttime</span> 
       </div> 
      </div> 
      <div class='po_008'> 
       <p class='po_009'>$post->message</p> 
      </div> 
      <div class='po_010'> 
      <?php if(isset($post->foto)){?> 
       <img class='myimage'src="userdata/<?php echo $post->foto->imagename;?>"> 
       <?php } ?> 
      </div> 
     </div> 
    <?php }      
} 
?> 

Answer 2

verwenden in echo-Anweisung:

<img class='myimage'src='userdata/'".$post->foto->imagename."'> 

Statt:

<img class='myimage'src='"userdata/".$post->foto->imagename."'>
