It is quite possible that I'm just looking for help finding the name of a function that already exists within drupal (7) but sometimes the documentation is a bit difficult to navigate. Hopefully someone can help me.
I have a node that has a custom field.
I am working within a template field--mycustomcontenttype.tpl.php
and so am trying to find the name of the PHP function that outputs and image field with image styles.
mycustomcontenttype
is a NODE with the following additional field:
[field_image] => Array
(
[und] => Array
(
[0] => Array
(
[fid] => 51
[alt] => ImageAltText
[title] =>
[width] => 150
[height] => 150
[uid] => 29
[filename] => myimagename.jpg
[uri] => public://myimagename.jpg
[filemime] => image/jpeg
[filesize] => 8812
[status] => 1
[timestamp] => 1339445372
[uuid] => a088ea8f-ddf9-47d1-b013-19c8f8cada07
[metatags] => Array
(
)
)
So I could display the image using an (ugly) hand rolled functions that takes the value found in $item['#options']['entity']->field_image
and does the substitution of public://
for the actual server path, and then it's also possible that I'm going to want to load the image with the correct drupal image style (thumbnail, custom-style, etc...)
Sadly, I just have no idea what the name of the function that works something like: unknown_function_name_drupal_image_print($item['#options']['entity']->field_image, 'thumnail');
is.
Is there anyone who can help me find this?
You are looking for image_style_url(style_name, image_url);
For example:
<?='<img src="'.image_style_url('fullwidth', $node->field_page_image['und'][0]['filename']).'" />'?>
EDIT
As pointed out you can also set the image style in the Manage Display page for the content type and then output using render.
<?php print render($content['field_image']); ?>
