Awesome plugin.

Have an issue when using a file attachment field to add an image. Just 1 image, its not a repeatable field. I’m using
```
<?php $portfolioThumb = simple_fields_get_post_value(get_the_id(), array(2, 4), true);
	echo "<span class='meta-value_portfolio-thumb'>$portfolioThumb</span>";?>
```
Instead of showing the image the images database number is displayed.

Looking at the database I see the meta_id, post_id and the following simple fields key and meta

_simple_fields_fieldGroupID_2_fieldID_4_numInSet_0 192

Any ideas?

Thanks

It’s actually meant to be like that. Since I don’t know what the developer wants to do with a file (show it? print the filename? output the dimensions?) the plugin only returns the file ID, and then you can use WordPress own functions to fetch more info about the file.

Useful functions include:

Quick illustration of how to show an image with Simple Fields:
```
<?php 

$selected_value = simple_fields_get_post_value(get_the_id(), "Your Image Field Name", true); 

$theImageURL = wp_get_attachment_url($selected_value);

echo '<img src="'.$theImageURL.'">';

?>
```

Thanks Beschizza, very helpful. I have another question though.

How do I add dimension “rules” to your code? You know, like when you pull a featured image from your post with this:
```
<?php 

	if ( function_exists("has_post_thumbnail") && has_post_thumbnail() ) { the_post_thumbnail(array(220,180), array("class" => "alignleft post_thumbnail")); } ?>
```
I want to use the Simple Fields plugin for thumbnail images.

Thanks.

Never mind, I just did this:
```
<?php
$selected_value = simple_fields_get_post_value(get_the_id(), "Thumbnail 1", true);
$theImageURL = wp_get_attachment_url($selected_value);
echo '<img src="'.$theImageURL.'" width="75" height="75">';
?>
```
