Function to Filter genesis_get_image with get_the_image Plugin WordPress

Adam W. Warner comments:

I think this got me closer, and yes, I'm certain my syntax was off;) I tried this and the first function worked as expected for the thumbnail, but the square image didn't get pulled in or filtered. Where the square image should be, there is a link to "default output" that links to the full post.

Do you have any thoughts on what may be happening?

add_filter('genesis_get_image', 'default_image_fallback', 10, 2);
function default_image_fallback($output, $args) {
if(!$output && $args['size'] == 'thumbnail' && $args['format'] == 'html' && function_exists( 'get_the_image' )){
$output = get_the_image(array(
'size' => 'thumbnail',
'image_scan' => 'true',
'width' => '150',
'height' => '150',
'image_class' => 'post-image'
));
} else {
$output = get_the_image(array(
'size' => 'square',
'image_scan' => 'true',
'width' => '110',
'height' => '110',
'image_class' => 'post-image'
));
}
return $output;
}

what about something like this? ;)

Thank you, that works great! However, I do need to add two more image sizes. I tried to add one and my lack of PHP syntax knowledge is showing again...after I added the "Mini Square" size I am getting an Parse error: syntax error, unexpected T_ELSE error on the the line that holds the } else { above the Mini Square code.

Either way, you win, but could you help me out with that syntax again?


add_filter('genesis_get_image', 'default_image_fallback', 10, 2);

function default_image_fallback($output, $args) {

if(!$output && $args['size'] == 'thumbnail' && $args['format'] == 'html' && function_exists( 'get_the_image' )){

$output = get_the_image(array(

'size' => 'thumbnail',

'image_scan' => 'true',

'width' => '150',

'height' => '150',

'image_class' => 'post-image'

));

} else {

$output = get_the_image(array(

'size' => 'square',

'image_scan' => 'true',

'width' => '110',

'height' => '110',

'image_class' => 'post-image'

));

} else {

$output = get_the_image(array(

'size' => 'Mini Square',

'image_scan' => 'true',

'width' => '70',

'height' => '70',

'image_class' => 'post-image'

));

}

return $output;

}

} elseif (!$output && $args['size'] == 'Mini Square' && $args['format'] == 'html' && function_exists( 'get_the_image' )) {
$output = get_the_image(array(
'size' => 'Mini Square',
'image_scan' => 'true',
'width' => '70',
'height' => '70',
'image_class' => 'post-image'
));
} else {
$output = get_the_image(array(
'size' => 'square',

'width' => '110',

));
}
return $output;
}

if/elseif/else statements works like this:

if(condition1) {
condition passed so this will be done
} elseif (condition2) {
condition1 dont pass, so we check for condition2. if it passes - this will be done.
} else {
nothing passed so we echo this out.
}

So, in your situation, we check if $args['size'] is equal to 'thumbnail'. If it IS equal - output will be 'thumbnail' image. If that argument wasn't equal to 'thumbnail', then we check if it is equal to 'Mini Square'. If it is - we form output with 'Mini Square' sized image. Else, if that argument was not equal to 'thumbnail', nor 'Mini Square' we default it to 'square' image ;) I hope that helps ;)

btw, this should also work, and might be easier for you to understand.


add_filter('genesis_get_image', 'default_image_fallback', 10, 2);
function default_image_fallback($output, $args) {

if(!$output && $args['size'] == 'thumbnail' && $args['format'] == 'html' && function_exists( 'get_the_image' )){
$output = get_the_image(array(
'size' => 'thumbnail',
'image_scan' => 'true',
'width' => '150',
'height' => '150',
'image_class' => 'post-image'
));
}

if(!$output && $args['size'] == 'Mini Square' && $args['format'] == 'html' && function_exists( 'get_the_image' )) {
$output = get_the_image(array(
'size' => 'Mini Square',
'image_scan' => 'true',
'width' => '70',
'height' => '70',
'image_class' => 'post-image'
));
}

if(!$output && $args['size'] == 'square' && $args['format'] == 'html' && function_exists( 'get_the_image' )){
$output = get_the_image(array(
'size' => 'square',
'image_scan' => 'true',
'width' => '110',
'height' => '110',
'image_class' => 'post-image'
));
}

return $output;
}

Simple if statements to check which condition will pass. Depends on $args['size'] ;)
So now, when you want to add any other image size, just add something like this to the function above:


if(!$output && $args['size'] == 'somenewsize' && $args['format'] == 'html' && function_exists( 'get_the_image' )){
$output = get_the_image(array(
'size' => 'somenewsize',
'image_scan' => 'true',
'width' => '110',
'height' => '110',
'image_class' => 'post-image'
));
}

As an aside, the last one (the easier one to understand) worked for thumbnail and Mini Square, but not square. The one above worked for all three image sizes.
