foreachループのブートストラップカルーセル

Question

これはブートストラップカルーセルのコードです。私は画像を動的に表示したい。しかし、ここには1つのイメージしか表示されていません...私はこれの背後にある問題が何であるか把握できません。

これは

<?php 
foreach($article_post as $row) { 
    if(!isset(unserialize($row->post_image)[0])){ 
     echo "No Image"; 
    } else { 
     $a=unserialize($row->post_image)[0]; 
     $b=unserialize($row->post_image); 
    } 
} 
?> 
<div class="col-md-8 col-xs-12 chng1"> 
    <?php if (count($b) == 1) { ?> 
     <img src="<?php echo base_url()."assets/".$a; ?>" width="100%" height="450" style="position:relative" class="img-wdth"> 
    <?php } elseif(count($b)>1) { ?> 
     <div id="myCarousel" class="carousel slide" data-ride="carousel"> 
     <!-- Wrapper for slides --> 
      <div class="carousel-inner"> 
       <div class="item active"> 
        <img src="<?php echo base_url()."assets/".$a?>" alt="Los Angeles"> 
       </div> 
      </div> 
     <!-- Left and right controls --> 
      <a class="left carousel-control" href="#myCarousel" data-slide="prev"> 
       <span class="glyphicon glyphicon-chevron-left"></span> 
       <span class="sr-only">Previous</span> 
      </a> 
      <a class="right carousel-control" href="#myCarousel" data-slide="next"> 
       <span class="glyphicon glyphicon-chevron-right"></span> 
       <span class="sr-only">Next</span> 
      </a> 
     </div>  
    <?php } ?> 
</div>

はこれを試してみてください私のコードです：browser..whatで

<?php foreach($article_post as $row){ 
        $c=0; 
        if(!isset(unserialize($row->post_image)[0])){ 
         echo "No Image"; 
        } 
        else{ 
         $a=unserialize($row->post_image)[0]; 
         $b=unserialize($row->post_image);?> 

<div class="col-md-8 col-xs-12 chng1"> 
<?php if (count($b) == 1) { ?> 

<img src="<?php echo base_url()."assets/".$a?>" width="100%" height="450" style="position:relative" class="img-wdth"> 
<?php } elseif(count($b)>1){ $c++; ?> 

<?php if($c==1){echo '<div id="myCarousel" class="carousel slide" data-ride="carousel"><div class="carousel-inner"><div class="item active">';} ?> 

    <!-- Wrapper for slides --> 


     <img src="<?php echo base_url()."assets/".$a?>" alt="Los Angeles"> 
<?php if($c==1){echo '</div></div>';} ?> 
<?php } } }?> 
<!-- Left and right controls --> 
    <a class="left carousel-control" href="#myCarousel" data-slide="prev"> 
    <span class="glyphicon glyphicon-chevron-left"></span> 
    <span class="sr-only">Previous</span> 
    </a> 
    <a class="right carousel-control" href="#myCarousel" data-slide="next">

<?php foreach($article_post as $row){ 

        if(!isset(unserialize($row->post_image)[0])){ 
         echo "No Image"; 
        } 
        else{ 
         $a=unserialize($row->post_image)[0]; 
         $b=unserialize($row->post_image); 

             ?> 

    <div class="col-md-8 col-xs-12 chng1"> 
    <?php if (count($b) == 1) { ?> 

    <img src="<?php echo base_url()."assets/".$a?>" width="100%" height="450" style="position:relative" class="img-wdth"> 
    <?php } elseif(count($b)>1){ //Greater than 1 then use another foreach 
     ?> 
    <div id="myCarousel" class="carousel slide" data-ride="carousel"> 
     <!-- Wrapper for slides --> 
     <div class="carousel-inner"> 
     <div class="item active"> 
      <?php foreach($b as $c){ ?>
