Unexpected Behavior of image field.

[peterpp]

My code is as below

<?php
$header_image = $page->header_image;
if( !empty($header_image) ){
    $head_image = $header_image->first();
    $img = $head_image->size(940,627);
}

The code was working fine for 2 months.

But now i am having issue with this image field. Sometimes image loads sometimes it doesnt loads. Somtime it throws arror sometimes gives broken image.

Plz help

Pravin

What error odes come up? Has the image changed? Server configuration?

Make sure that the error is not something on the client side (e.g. AdBlock blocking, firewal, Browsercache).

From the ProcessWire perspective, you might want to manually delete the cache (/site/assets/cache) and remove all variations of this image. To do this, go to the folder of the image (under /site/assets/files/<pageid>/, just look at the URL of the image to get the ID) and then remove all files from this image (e.g. image.jpg, image.100x0.jpg image.940x627.jpg,...).

I'd guess your image field is multiple cause of the ->first()

It, the field, should be name then header_images

I think empty() isn't worth using here

if( $page->header_images->count ){
    $head_image = $page->header_images->first();
    $img = $head_image->size(940,627);
    ...
} else {
    // no image
}

If there were a issue with image field many would have this problem, but it's not.

It's expected behaviour of the Pageimages (array)

You're trying to set a pixel size to an array of images. Pageimages (array of images) doesn't have a size, because it is an array.

You need to go 1 step deeper, get the image, then set the size to an individual image.

If you run the code below, what does it say ?

if ($page->header_image instanceof Pageimage) {
    echo "(Pageimage) - Single image, yeah, you can use size.<br>";
} elseif ($page->header_image instanceof Pageimages) {
    echo "(Pageimages) - Array of images, can't use size.<br>";
}

I solved the issue. I set Maximum Files allowed to 0 in the header_image field setting. Then i removed size from template and placed $header_image = $page->header_image->first();

Thanx for your help.

This solved my problem.
