如何配置此正確

Question

我想這所以它記錄錯誤，它的工作原理，但I`

<?php 
if(!empty($err)) { 
    echo "<div class=\"msg\">"; 
    foreach ($err as $e) { 
    echo "* $e <br>"; 
    } 
    echo "</div>";  
    } 
?> 

我想要將它添加到

<div class="alert alert-app-level alert-danger"> 
     <div class="alert-item"> 
    <div class="alert-text"> 
     LOGIN ERROR TEXT HERE 
    </div> 
    </div> 
</div> 

Answer 1

試試這個，

<?php 
$error = array("test1","test2"); 
$html = ""; 
if($error) { 
    $html .= '<div class="alert alert-app-level alert-danger"> 
       <div class="alert-item"> 
       <div class="alert-text">'; 
    foreach ($error as $e) { 
     $html .= "<p>".$e."</p>"; 
    } 
    $html .= '</div> 
       </div> 
       </div>'; 
echo $html; 
} 
?>

PHP嵌入在HTML和封裝在div標籤用於進一步CSS-定製（每個錯誤消息不需要任何<br>更多）：

<div class="alert alert-app-level alert-danger"> 
    <div class="alert-item"> 
     <div class="alert-text"> 
      <?php 
      if (!empty($err)) { 
       ?> 
       <div class="msg"> 
        <?php 
        foreach ($err as $e) { 
         ?> 
         <div class="error">* <?php echo $e; ?></div> 
         <?php 
        } 
        ?> 
       </div> 
       <?php 
      } 
      ?> 
     </div> 
    </div> 
</div>
