Hello,

I’m trying to display all clients testimonials on my home page. Testimonials are by projects, so they are in each individual project page under the form of a structured field (quote, name of the client, role, client picture).

So I tried this:

```auto
<?php foreach(page('projects')->children()->pluck('clientTestimonials')->toStructure()->limit(2) as $testimonial): ?>

```

and have the error “Fatal error: Call to a member function children() on boolean in /templates/home.php on line 274”

Then I tried this:

```auto
<?php foreach(page('projects')->children->clientTestimonials()->toStructure()->limit(2) as $testimonial): ?>

```

with non luck either

Same error message as above + “Notice: Trying to get property of non-object in /templates/home.php on line 274”

Does a structured field can be plucked ? How can I do what i want to do ? With 2 `foreach` ?

Thanks

You can’t use `pluck()`. Check out [this post for a solution](https://forum.getkirby.com/t/merging-combining-structure-fields/2766/8).

thank you.

I tried this:

```
<?php
$projects = page('project')->children()->visible();
	$testimonials = new Structure();
	foreach($projects as $p) {
	$testimonials = $testimonials->merge($p);
	}
	foreach($testimonials as $testimonial):
?>

```

with no success and this error message:

> Notice: Undefined property: Page::$data in /kirby/toolkit/lib/collection.php on line 40  
> Warning: Invalid argument supplied for foreach() in /kirby/toolkit/lib/a.php on line 463

Use the example (see below) before with the $key, that last one does not work.

```auto
<?php
$subaktuelles = $site->index()->findBy("uid", "aktuell")->children()->visible();
$neuigkeiten = new Structure();
$key = 0;
foreach($subaktuelles as $p) {
  foreach($p->news()->toStructure() as $item) {
    $neuigkeiten->append($key, $item);
    $key++;
  }
}

foreach ($neuigkeiten->sortBy('date', 'desc') as $neuigkeit): ?>

```

</div>

Ok I tried it, it kinda works.

first problem:  
`<?php foreach ($testimonials as $testimonial): ?>` gives me all the testimonials “plucked” and it seems that i can’t chain `->shuffle()` or `->limit(3)` to it (in your example you can sort it and chain easily). Is this normal ?

Second problem:  
`<?php echo $testimonial->clientTestimonial()->kt() ?>` echoes the `clientTestimonial` field (great) but all the others fields echo the same thing, for example `<?php echo $testimonial->clientTestimonialName() ?>` also echoes `clientTestimonial` instead of the right field and I can’t find why.

any ideas ?

//Edit : in fact the first testimonial is empty, the second is just the quote repeated, the third is just the name, the fourth is just the role etc… I’m going to investigate.

//Edit 2: in fact it’s repeating only one of the items over and over.

Sure:

```
<?php
$projects = page('projets')->children()->visible();
$testimonials = new Structure();
$key = 0;
foreach($projects as $p) {
  foreach($p->clientTestimonials()->toStructure() as $item) {
    $testimonials->append($key, $item);
    $key++;
  }
}
foreach ($testimonials as $testimonial): ?>
<!--some html ul li for repeated item-->
<blockquote>
<?php echo $testimonial->clientTestimonial()->kt() ?>
</blockquote>
<p><strong><?php echo $testimonial->clientTestimonialName() ?></strong><span><?php echo $testimonial->clientTestimonialRole() ?></span></p>
 <!--end of html block-->
<?php endforeach ?>

```

and the datas:

```

Hm, I’m very sorry, I can’t spot anything wrong here; I have the same sort of structure in one of my projects and use the same code without any problems …

Very strange, it’s like the foreach is on the wrond code, I will look it further but I’m neraly stuck on that.

Thanks for your help.

OK, i don’t know why as I just copied the code from above, but this time it works!

```
<?php
$projects = page('projets')->children()->visible();
$testimonials = new Structure();
$key = 0;
foreach($projects as $p) {
  foreach($p->clientTestimonials()->toStructure() as $item) {
    $testimonials->append($key, $item);
    $key++;
  }
}
foreach ($testimonials->limit(3) as $testimonial): ?>									
<!--some html markup-->
<?php echo $testimonial->clientTestimonial()->kt() ?>
<?php echo $testimonial->clientTestimonialName() ?>
<?php echo $testimonial->clientTestimonialRole() ?>
<!--end of html markup-->
<?php endforeach ?>

```

As it’s the same code, maybe my data were corrupted or the data syntax not right on one page.

Last question though: I can’t `shuffle()` anything anywhere, dont know why it doesn’t work altough `limit()` works fine now.

The error when I try to do `foreach ($testimonials->shuffle()->limit(3) as $testimonial)` :

> Fatal error: Call to a member function clientTestimonial() on integer in /site/templates/home.php on line 288

When I try to shuffle on others collections, it does not drop error but it doesn’t shuffle anything

Thank you @texnixe for your help!

Yes, that’s a known issue; the structure collection has some limitations compared to other collections.

Glad you sorted it out.

</div>

Ok, any idea on how I can shuffle it with vanilla php ? And why when I shuffle on the first collection `page('projets')->children()->visible()->shuffle` I always end with the same result ?

I think, currently the only way to achieve that would be to use the `yaml()` method instead of `toStructure()` and then shuffle the array.

I encountered that problem back in [August last year](https://github.com/getkirby/kirby/issues/288), but it hasn’t been fixed since.

</div>

I had this idea too but I didn’t know how to implement it. Where can I put the yaml ?

Also I don’t understand why when I shuffle the first pages collection it doesn’t change anything, at least the testimonials had to be shuffled by page.

</div>

The content would be unchanged, but instead of using `toStructure` in your template you would use `yaml`. It returns a plain PHP array that can be manipulated with the standard PHP functions.  
You would also use a plain array for `$testimonials` instead of a `new Structure()`. You can add items to an array with `$testimonials[] = $item`.

</div>

some follow up, a friend of mine helps me for achieving this, and I post the code here if it can help somebody else.

My first code, works but no random:

```
<?php
                $projects = page('projets')->children()->visible();
                $testimonials = new Structure();
                $key = 0;
                foreach($projects as $p) {
                  foreach($p->clientTestimonials()->toStructure() as $item) {
                    $testimonials->append($key, $item);
                    $key++;
                }
            }
            foreach ($testimonials->limit(5) as $testimonial): ?>									
            <li class="item">
               <div class="testimonial-block">
                <blockquote>
                    <?php echo $testimonial->clientTestimonial()->kt() ?>
                </blockquote>
                <div class="testimonial-avatar"><img src="http://placehold.it/100x100&amp;text=IMAGE+PLACEHOLDER" alt="" height="60" width="60"></div>
                <div class="testimonial-info">
                    <div class="testimonial-info-in">
                        <strong><?php echo $testimonial->clientTestimonialName() ?></strong><span><?php echo $testimonial->clientTestimonialRole() ?></span>
                    </div>
                </div>
            </div>
        </li>
    <?php endforeach ?> 

```

the code with “all array” in vanilla PHP + randomisation and limit to 5 items:

```
<?php
$projects = page('projets')->children()->visible();
$testimonials = array();
foreach($projects as $p) {
  foreach($p->clientTestimonials()->yaml() as $item) {
    $testimonials[] = $item;
  }
}
shuffle($testimonials);
$testimonialscount = count($testimonials);
$i = 0;
while($i < 5) { ?>
	<li class="item">
               <div class="testimonial-block">
                <blockquote>
                    <?php echo $testimonials[$i]["clientTestimonial"]; ?>
                </blockquote>
                <div class="testimonial-avatar"><img src="http://placehold.it/100x100&amp;text=IMAGE+PLACEHOLDER" alt="" height="60" width="60"></div>
                <div class="testimonial-info">
                    <div class="testimonial-info-in">
                        <strong><?php echo $testimonials[$i]["clientTestimonialName"]; ?></strong><span><?php echo $testimonials[$i]["clientTestimonialRole"]; ?></span>
                    </div>
                </div>
            </div>
        </li>
<?php	$i++;
if($i >= $testimonialscount): break; endif;
}
?>

```

Thanks everybody!

you’re welcome.

I edited my code with a solution to avoid the offset limit problem (if you set 5 items but the array have only 3 of them for example)
