image size issue

[eze102]

Hi - can someone explain to me why I can't modify image size with the following code?

                                        <?
                                        foreach($page->call_to_action as $cta) {
                                            $count++;
                                            $class = ($count == 2) ? "one_half last" : "one_half";
                                            $img = $cta->image->size(300,300);
                                            echo "<div class='{$class}'>
                                                <a href='{$cta->call_to_action_url}' class='over'>
                                                        <span>{$cta->overlay_title}</span>
                                                            <p>{$cta->overlay_description}</p>
                                                    </a>
                                                    <a href='{$cta->call_to_action_url}'><img src='{$img->url}'</a>
                                            </div>";
                                        }
                                        ?>

Sorry, I don't get what you are asking for?!

Can you explain a bit more what your code does or does not and what you want to be the result?

Also I'm not sure, but the original image URL in the a-tag, shouldn't it be:

<a href='{$cta->call_to_action->url}'
                              ^^      = -> instead of _ ??

[eze102]

Yes, I'm sorry. That was not clear!

I created a repeater field called "call_to_action" with a few subfields, including "overlay_title" , "overlay_description" , "image" , and "call_to_action_url".

I wanted to iterate over the "call_to_action" fields and output them, which is working; I also wanted to resize the image in the image field, but that isn't working... even though I did:

 $img = $cta->image->size(300,300);

Aha!

You need to debug what your $cta->image really holds.

• [ ] check if the fieldname is correct (image or images or other?)
• [ ] check if the image field is set to single-mode, what is
• [ ] put a line into your code to inspect the value (see *1)

*1)

foreach($page->call_to_action as $cta) {
    $count++;
    $class = ($count == 2) ? "one_half last" : "one_half";
    $img = $cta->image->size(300,300);

// debug $img:
echo "<pre>\n\n";
var_dump($img);
die('RIP :: ' . __FILE__ . ':' . __LINE__);

    echo "<div class='{$class}'>
        <a href='{$cta->call_to_action_url}' class='over'>
        	<span>{$cta->overlay_title}</span>
            <p>{$cta->overlay_description}</p>
        </a>
        <a href='{$cta->call_to_action_url}'><img src='{$img->url}' /></a>
    </div>";
}

BTW: in your code the img tag is unclosed (/>), and your code does not check if an image is really set for each repeater item. Or is the image field set to be required in the template?

Thank you! I still can't seem to access the size property of the image though.

Fieldname is correct and image is in single mode.

And when I add your debug code, I get like 5000 lines of output in the browser that I can't understand (I'm not very experienced with PHP). The code does not just stop the file and show the img value, it shows tons of lines of code...

[eze102]

Actually, now none of the calls to $cta properties are working, except:

$cta->call_to_action_url

[eze102]

Is there something wrong with my code in general?

[eze102]

Welp, seems like the only way to resize the image was by resizing the container in CSS!
