Acces picture 1 to 4 of an imagefield

[justnew77]

Hi,

I got an image field named: imageK1.

How can I call e.g. the second image?

What I want do do:

I want to list the first 4 images of the field.

Cheers

It took me a while too: $image = $page->imageK1->first(2);

There are a few ways you could do this, but this approach is pretty straight-forward:

$i=0;
foreach($page->imageK1 as $image){
    if($i==4) break;
    echo $image->url;
}

Or if you do want to specify the second image, you are looking for ->eq(1), remembering that numbering starts from 0, so 1 is actually the second image.

EDIT: Sorry, see corrected code below: http://processwire.com/talk/topic/5359-acces-picture-1-to-4-of-an-imagefield/?p=51662

Both thing do not work:

 $i=0;
	foreach($page->imageK1 as $imageK1){
    	if($i==4) break;
    	echo "<a class='fancybox' rel='gallery1' href='$imageK1->url'>";
    	echo "<img src='$imageK1->url' height='150'></a>";
	}

the code above put out ALL images.

and

 echo $image = $page->imageK1->first(2);
    echo $image = $page->imageK1->first(3);
    echo $image = $page->imageK1->first(4);
    echo $image = $page->imageK1->first(5);

put out only the filename of the FIRST image, 4 times!

$images = $page->images->slice(0,3);

And, you have to put it into html to show the image instead of the filename <img src='{$page->imageK1->first(2)->url}' /> (or adapt Soma's solution to this).

There is no argument to first() its always the first.

I'm obviously a beginner....

 echo $images = $page->images->slice(0,3); 

get me an Error: Call to a member function slice() on a non-object

If you're using Soma's slice approach, you need to use your image field: imageK1

echo $images = $page->imageK1->slice(0,3); 

Did you try $page->imageK1->eq(1)->url; rather than those first(x) which won't work because of what Soma mentioned?

PS There was a slight omission in my original code. I missed the counter to up the value of $i on each loop.

This should work just fine to echo out the first four images

$i=0;
foreach($page->imageK1 as $image){
    if($i==4) break;
    echo "<a class='fancybox' rel='gallery1' href='$image->url'>";
    echo "<img src='$image->url' height='150'></a>"
    $i++;
}

I thought I should also clarify that if you use Soma' approach, you will still need to iterate through the $images array like this:

$images = $page->imageK1->slice(0,3);
foreach($images as $image){
    echo "<a class='fancybox' rel='gallery1' href='$image->url'>";
    echo "<img src='$image->url' height='150'></a>"
}

Thank you all for your help
