IF image THEN ...	Can't Post

How do I display some text ONLY if an image is uploaded/present?

Example:

IF
<?php if ($upload['hasThumbnail']): ?>
THEN
 Click to view larger image

Thanks,
Brian

Hi Brian, try this:

Code

<?php if ($upload['hasThumbnail']): ?>  
  ... 
  <br /><span>Click to view larger image</span>  
<?php endif; ?>

And you can display something if there is no image like this:

Code

<?php if ($upload['hasThumbnail']): ?>  
  ... 
  <br /><span>Click to view larger image</span>  
<?php else: ?> 
  Sorry, no image! 
<?php endif; ?>

Hope that helps!

Re: [Dave] IF image THEN ... [In reply to]	Can't Post

Okay, this is kind of what I'm looking for, except I need more fine tuning...

What do I put if I don't want to include the text for each image. So for example, I only want this line,
 Click to view larger image
to be added once.

Here is what I am working with now, which returns up to four lines if I have all four images uploaded:

<?php foreach (getUploads($options['tableName'], 'other_images', $record['num']) as $upload): ?>
<?php if ($upload['hasThumbnail']): ?>
<a href="<?php echo $upload['urlPath'] ?>"><img src="<?php echo $upload['thumbUrlPath'] ?>" width="<?php echo $upload['thumbWidth'] ?>" height="<?php echo $upload['thumbHeight'] ?>" alt="<?php echo $upload['filename'] ?>" title="<?php echo $upload['info1'] ?>" /></a>
<?php endif ?>
<?php endforeach ?>
<?php foreach (getUploads($options['tableName'], 'other_images', $record['num']) as $upload): ?>
<?php if ($upload['hasThumbnail']): ?>
Click on small photos to enlarge
<?php endif ?>
<?php endforeach ?>

Thanks,
Brian

Re: [Dave] IF image THEN ... [In reply to]	Can't Post

Also, I am looking for a way to return an image and not just text, except the image is not uploaded via CMS Builder. I am trying to display a "Sorry, No Image" image when there is not an image uploaded to represent the product. Here is what I have:

<?php foreach (getUploads($options['tableName'], 'thumbnail_image', $record['num']) as $upload): ?>
<?php if ($upload['hasThumbnail']): ?>
<img src="<?php echo $upload['thumbUrlPath'] ?>" width="75" height="75" alt="inset photo" />
<?php else: ?>
<img src="/images/NoImage-thumbnail2.jpg" width="75" height="75" alt="inset photo" />
<?php endif ?>
<?php endforeach ?>

It doesn't work the way I have it currently.

Thanks,
Brian

Hi Brian,

Do you have a mockup html page that shows the effect or design you're going for? That might help us get there quicker.

>What do I put if I don't want to include the text for each
>image. So for example, I only want this line, 
>Click to view larger imageto be added once.

If you only want to print one image, you can break out for a foreach loop (and stop looping over additional images) with the break function, like this: <?php break; ?> Just put that after the text you want displayed.

>I am trying to display a "Sorry, No Image" image when there
>is not an image uploaded to represent the product. Here is
>what I have ... It doesn't work the way I have it currently.

Try replacing this line:

Code

<?php foreach (getUploads($options['tableName'], 'thumbnail_image', $record['num']) as $upload): ?>

With these lines:

Code

<?php $uploads = getUploads($options['tableName'], 'thumbnail_image', $record['num']); ?>  
<?php foreach ($uploads as $upload): ?>

Then you'll be able to test if there was any images _after_ your foreach loop like this:

Code

<?php $uploads = getUploads($options['tableName'], 'thumbnail_image', $record['num']); ?>   
 
<?php foreach ($uploads as $upload): ?> 
<?php if ($upload['hasThumbnail']): ?> 
  <img src="<?php echo $upload['thumbUrlPath'] ?>" width="75" height="75" alt="inset photo" /> 
<?php endif ?> 
<?php endforeach ?> 
 
<?php if (count($images) == 0): ?> 
  <img src="/images/NoImage-thumbnail2.jpg" width="75" height="75" alt="inset photo" /> 
<?php endif ?>

Let me know it goes!

Dave, I tried your suggestions but it did not work.

If you take a look at www.owenequipmentsales.com/product.php/1-1/

you will see that the text "Click on small photos to enlarge" appears below the main product image, but there are no small photos featured. I need an IF/THEN statement that will detect when no small photos are uploaded and then NOT display the text. So only display the text when small photos are uploaded.

Let's take care of this one first and then I will address the other IF/THEN statement issue regarding the display of the "Sorry, No Image" image when main product image not uploaded.

I appreciate your help with this!

Thanks,
Brian

Hi Brian,

So you want it to show "Click on small photos..." only once if there is any images uploaded? Is that right? Try this:

Code

<?php if (count($images) > 0): ?>  
  Click on small photos to enlarge 
<?php endif ?>

And feel free to attach your viewer if you need more help and I'll take a look at your code.

Re: [Dave] IF image THEN ... [In reply to]	Can't Post

Dave, that worked to remove the text when other images are not uploaded but now I get an error when there are other images uploaded, as with this page: http://www.owenequipmentsales.com/product.php/14-23/

Notice: Undefined variable: images in /.../public_html/include-ProductRecordInsert.php on line 47

See the include file attached which contains the viewer code.

Thanks,
Brian

Re: [rasbro] IF image THEN ... [In reply to]	Can't Post

Thanks, try this:

Code

<td colspan="2" id="sumimg-otherimages"><br /> 
 
  <?php $otherImages = getUploads($options['tableName'], 'other_images', $record['num']); ?> 
 
  <?php foreach ($otherImages as $upload): ?> 
    <?php if ($upload['hasThumbnail']): ?> 
      <a href="<?php echo $upload['urlPath'] ?>"><img src="<?php echo $upload['thumbUrlPath'] ?>" 
         width="<?php echo $upload['thumbWidth'] ?>" height="<?php echo $upload['thumbHeight'] ?>" 
         alt="<?php echo $upload['filename'] ?>" title="<?php echo $upload['info1'] ?>" /></a> 
    <?php endif ?> 
  <?php endforeach ?> 
 
  <?php if (count($otherImages) > 0): ?>   
    <p id="otherimages-clicklarger">Click on small photos to enlarge</p> 
  <?php endif ?>   
 
</td>

Here's how it works. First, we load the uploads from the 'other_images' field into $otherImages. Next, we loop over those and for each one that has a thumbnail we display it. Finally, we check the count of 'other_images' and if there is 1 or more uploads we display the "Click on small photos..." text.

Let me know how it goes!

Phew, that finally did it!

Thanks Dave!

Hey, what do you think about the other IF/THEN statement issue regarding the display of the "Sorry, No Image" image when main product image not uploaded? Any ideas? Refer to same viewer in the include file I attached earlier.

Thanks,
Brian

Great, glad to hear it's working! For the other it's the same idea:

Code

<td id="sumimg-mainimage"> 
 
  <?php $mainImages = getUploads($options['tableName'], 'main_image', $record['num']) as $upload); ?> 
   
  <?php foreach ($mainImages as $upload): ?> 
    <?php if ($upload['hasThumbnail']): ?> 
      <a href="<?php echo $upload['urlPath'] ?>"><img src="<?php echo $upload['thumbUrlPath'] ?>" 
       width="<?php echo $upload['thumbWidth'] ?>" height="<?php echo $upload['thumbHeight'] ?>" 
       alt="Product Main Image - <?php echo $upload['filename'] ?>" title="<?php echo $record['name'] ?>" /></a> 
    <?php endif ?> 
  <?php endforeach ?> 
   
  <?php if (count($mainImages) == 0): ?>   
      <img src="/images/NoImage-main.jpg" alt="NoImage-main.jpg" /> 
  <?php endif ?>   
 
</td>

Let me know if that does it.

Re: [Dave] IF image THEN ... [In reply to]	Can't Post

Dave, once I discovered this error in the code you gave me...

<?php $mainImages = getUploads($options['tableName'], 'main_image', $record['num']) as $upload); ?>

and changed it to...

<?php $mainImages = getUploads($options['tableName'], 'main_image', $record['num']); ?>

then it worked great.

Thanks!
