Call 3 fields from child to parent page - stuck

[Franko]

I'm just trying to call 3 fields from a child page and list them on the parent page for a products list.

Here is the code. I can get the title and product description to pull but not the image. I also would like set the hight and width but every time I uncomment that it creates an error. 

foreach($page->children as $product) {

 

    if($product->image) {

       // $image = $product->image->width(150);

        $img = "<img src='{$image->url}' alt='{$product->title}' class='flt-left-img' />";

    } 

    

    else {

     

        $img = "<span class='image_placeholder'>Image not available</span>";

    } 

 

    echo "

        $img

        <h3>{$product->title}</h3>

        <p>{$product->product_description}</p>

        <hr />

        ";

}

?>

 

Advise would be appreciated.

Depends what field "image" is really. If it's single image field your code would be fine.

If it allows more than 1 image it will be a WireArray, and your code would fail. Then you'd need to treat it as such using

if($product->image->count){ ... }

Then you'd access images in the array using a foreach loop, or with one of the array functions $product->image->first()->url or $product->image->eq(n)->url

If that's the case you might want to set "image" to allow only 1 image (as the name suggests) ,then your code would work and be consistent with the naming. 

After all I could have also linked to the other 1'000'000 threads about this very same image field problem everybody has.  

But maybe it's just enough to link to the documentation which explains this again. https://processwire.com/api/fieldtypes/images/

It was just the setting for the image. Thank you. It's works when I add this code to the template file but will not work if I use Hanna Code. I cannot get hanna code to output php from body content. I do have it set in body setting but still wont work.

Can you please provide a screenshot of your configuration for this Hanna Code?  Does other Hanna Code work?
