Fetching results from database in PDO - php

Question

I developed a simple upload photo and comment system. When I use for each, it repeats the image. E.g If there are 5 comments on a photo. It repeats the photo 5 times with the 5 different comments. Instead of one image for 5 comments.
I want 1 image with each comments. How do I get all the comments for each photo without repeating the photo?
I use PDO and here is the php code:
<?php
//This is for the images
$results = $connecDB->prepare("select image,caption,id from gallery order by id desc LIMIT $start, $limit ");
$results->execute();
$results = $results->fetchAll();
foreach($results as $results) {
$pid=$results["id"];
//This is for the comments
$re= $connecDB->prepare("select * from comments where pid = :pid order by id");
$re->bindParam(':pid', $pid);
$re->execute();
foreach($re as $re) {
$name=$re["name"];
$comment=$re["comment"];
?>
<div class="item" id="item-<?php echo $results['id']?>">
<p><img src="../upload/images/<?php echo $results['image']?>" height="500px" width="500px"</p>
<p><?php echo $results['caption']?></p>
<div class="large-2 columns small-3"><font color="#3366ff"><?php echo $name?></font></div>
<div class="large-10 columns"><p><?php echo $comment?></p></div>
<?php}
}?>
Thanks.

Answer 1

You were looping everything inside inner loop, try like this.
<?php
//This is for the images
$results = $connecDB->prepare("select image,caption,id from gallery order by id desc LIMIT $start, $limit ");
$results->execute();
$results = $results->fetchAll();
foreach($results as $results) {
$pid=$results["id"];
?>
<div class="item" id="item-<?php echo $results['id']?>">
<p><img src="../upload/images/<?php echo $results['image']?>" height="500px" width="500px" /></p>
<p><?php echo $results['caption']?></p>
<?php
//This is for the comments
$re= $connecDB->prepare("select * from comments where pid = :pid order by id");
$re->bindParam(':pid', $pid);
$re->execute();
foreach($re as $re) {
$name=$re["name"];
$comment=$re["comment"];
?>
<div class="large-2 columns small-3"><font color="#3366ff"><?php echo $name?></font></div>
<div class="large-10 columns"><p><?php echo $comment?></p></div>
<?php}?>
</div>
<?php}?>

Actually you are not getting the result in $re variable. You need to fetchAll data after executing the query. As well as you were looping everything in inner foreach.
foreach($results as $results) {
$pid=$results["id"];
//This is for the comments
$re= $connecDB->prepare("select * from comments where pid = :pid order by id");
$re->bindParam(':pid', $pid);
$re->execute();
$comments = $re->fetchAll();
<div class="item" id="item-<?php echo $results['id']?>">
<p><img src="../upload/images/<?php echo $results['image']?>" height="500px" width="500px"</p>
<p><?php echo $results['caption']?></p>
<div class="large-2 columns small-3"><font color="#3366ff"><?php echo $name?></font></div>
foreach($comments as $re) {
$name=$re["name"];
$comment=$re["comment"];
?>
<div class="large-10 columns"><p><?php echo $comment; ?></p></div>
<?php}
}?>
