check if specific row exists mysql - php

Question

I have a mysqli query which fetches all the images from the table(I have 5 images that I display). I am using a jquery slider to display them. The problem is if there are no 5 images I see blank page like if the user uploads just two images then the rest three thumbnails will be empty and when you click on them it shows empty area. I don't want that happen so how do I only show the thumbnail if the image exists instead of showing empty thumbnail?
I tried the below but this doesn't work. I just need to see if image_one exists then show the thumbnail and the same for the rest of the images.
<?php
$stmt = $mydb->prepare("SELECT * FROM table where title = ? AND id = ? limit 1 ");
$stmt->bind_param('ss', $title, $id);
$stmt->execute();
$result = $stmt->get_result();
while ($row = $result->fetch_assoc()) {
$path = 'images/';
?>
<div id="slides">
<?php if($result->num_rows > 0){?><div class="slide"><a class="fancybox" href="<?php echo $path.$row['image_one']?>" data-fancybox-group="gallery"><img class="cloudzoom appsld" src="<?php echo $path.$row['image_one']?>"/></a></div><?php };?>
<?php if($result->num_rows > 0){?><div class="slide"><a class="fancybox" href="<?php echo $path.$row['image_two']?>" data-fancybox-group="gallery"><img class="cloudzoom appsld" src="<?php echo $path.$row['image_two']?>"/></a></div><?php };?>
<?php if($result->num_rows > 0){?> <div class="slide"><a class="fancybox" href="<?php echo $path.$row['image_three']?>" data-fancybox-group="gallery"><img class="cloudzoom appsld" src="<?php echo $path.$row['image_three']?>"/></a></div><?php };?>
<?php if($result->num_rows > 0){?><div class="slide"><a class="fancybox" href="<?php echo $path.$row['image_four']?>" data-fancybox-group="gallery"><img class="cloudzoom appsld" src="<?php echo $path.$row['image_four']?>"/></a></div><?php };?>
<?php if($result->num_rows > 0){?><div class="slide"><a class="fancybox" href="<?php echo $path.$row['image_five']?>" data-fancybox-group="gallery"><img class="cloudzoom appsld" src="<?php echo $path.$row['image_five']?>"/></a></div><?php };?>
</div>
<div id="slide_menu">
<ul id="slide"> <!-- This is the thumbnail area -->
<li class="fbar"> </li>
<?php if($result->num_rows > 0){?><li class="menuItem"><img src="<?php echo $path.$row['image_one']?>" /></li><?php }; ?>
<?php if($result->num_rows > 0){?><li class="menuItem"><img src="<?php echo $path.$row['image_two']?>" /></li><?php }; ?>
<?php if($result->num_rows > 0){?><li class="menuItem"><img src="<?php echo $path.$row['image_three']?>" /></li><?php }; ?>
<?php if($result->num_rows > 0){?><li class="menuItem"><img src="<?php echo $path.$row['image_four']?>" /></li><?php }; ?>
<?php if($result->num_rows > 0){?><li class="menuItem"><img src="<?php echo $path.$row['image_five']?>" /></li><?php }; ?>
</ul>
</div>

Answer 1

we can not see your database design so look at your default value for
image_one and so on
The row count is allways 0 or 1 (because of Limit 1)
Important are the fields image_one to image_five
These fields are always present, regardless of whether they are empty or with file names are filled.
depending on the default value test it
for example one of
if ($row['image_one'] > '') {
if ($row['image_one'] > null {
put an if arround building html.
<?php if($result->num_rows > 0){?>
<?php if ($row['image_one'] > '')
{?>
<li class="menuItem">
<img src="<?php echo $path.$row['image_one']?>" />
</li>
<?php
}?>
.... next 4 other tests
<?php if ($row['image_two'] > '')
....
<?php } // END__$result->num_rows > 0 ?>

Answer 2

try something like
...
<ul id="slide"> <!-- This is the thumbnail area -->
<li class="fbar"> </li>
<?php
foreach ( $row as $element => $val){
if(isset($val)) {
print "<li class='menuItem'><a href=''><img src=".$path.$val."/></a></li>";
}
}
?>
</ul>
...
and the same for the 1st (<div id="slides">) block

Answer 3

Im not 100% sure for pdo but its not too far away
<?php
$sql = "SELECT * FROM table where title = $title AND id = $id limit 1 ";
$result = mysql_query($sql);
while ($row = mysql_fetch_array($result)) {
?>
<div class="slide">
<a class="fancybox" href="images/<?php echo $row['DB-IMAGE-PATH-HERE']; ?>" data-fancybox-group="gallery">
<img class="cloudzoom appsld" src="images/<?php echo $row['DB-IMAGE-PATH-HERE']; ?>"/>
</a>
</div>
<?php } // end while loop ?>
</div> <!-- end id="slides" -->
