Correct syntax to list an array

[zigojacko]

I need to list an array (comma separated) and the data I need is available in the var_dump. I just don't know how to write the syntax to display the array list.

 

From within: var_dump ($product->getMediaGalleryImages());

 

I can see multiple instances of: ["url"]=> string(89) "https://www.example.com/media/catalog/product/x/x/x-image.jpg"

 

What do I need to write in order to list all the ["url"]

 

Thanks in advance.

Did you try the manual?

Did you try the manual?

 

Of course. It's the first place I look.

 

I couldn't resolve it after trying things from the manual...

 

Syntactically, I don't think this is right:-

$array = array($product->getMediaGallery());

So, the following returns NULL:-

var_dump ($array["url"]);

In case you've missed the obvious, I'm not really sure what I am doing with this hence why I have come here for help.

You indicated in your first post that $product->getMediaGallery() was already returning an array, so you do not need to wrap it in another array.

Just to clarify, does $product->getMediaGallery() contain an array? If so, you should be able to use a foreach loop (or loops) to get all the 'url' parts.

If you couldn't use the manual to figure out this problem, how the heck are you writing all your other php code?

 

$str = '';
foreach($array as $item)
$str .= $item .', ';
$str = trim($str,',');
echo $str;

 

OR the simpler approach:

 

$str = implode(',',$array);
echo $str;

 

I think you should spend some time reading the manual and getting familiar with the language you have chosen to use.

I don't think I explained well (or correctly). I think $product->getMediaGallery() is an object. The output of var_dump ($product->getMediaGalleryImages()); is below:-

I have replaced references to the domain with example.com.

 

I need to print a list of the ["url"] that can be seen in this var_dump and I don't know the correct syntax to do this.

 

Hope that explains a bit better.

Ah, well that's an entirely different thing. You cannot directly access those object properties because they are protected. It's returning a Varien_Data_Collection object, so you need to look there to figure out how to extract the data.

Thanks for your replies. I figured it out now...

$gallery_images = Mage::getModel('catalog/product')->load($product->getId())->getMediaGalleryImages();

$items = array();

foreach($gallery_images as $g_image) {
    $items[] = $g_image['url'];
}

Then I could fetch them outside of the loop with:-

implode(', ', $items);

Thanks for your replies anyway...

No problem, glad you figured it out!
