how get specific image size, from field, via php? was created by pabro

Hi,

how can i get an image, defined in custom image field, in template (item.php) via php?

I know, with

Code:

$this->fields['imagefield']->display

i get the resized image. But how can i get a specific size like small, big, medium, and original resource (with php)?

the image URLs are in the variables:

Merci!!

Is there also a variable for the original image path (without resize)?

This is somewhat complex to work in all cases, you can easily get original image name but not full path

we have 3 cases, DB-mode, folder-mode, default image, i think we could add a property to the image field

e.g. in category_items.php file:

Code:

$img_field_name = 'field11';
$img_field = & $items[$i]->fields[$img_field_name];

if ( !empty($img_field->value[0]) )  {

	$value = unserialize($img_field->value[0]);
	
	if ( !empty($img_field->value[0]['is_default_value'] ) ) {
		$original_path  = JPATH_BASE .DS. $value['default_image'];
	} else if ($img_field->parameters->get('image_source') &&  ) {
		$original_path  = JPATH_BASE .DS. $img_field->parameters->get('dir');
		$original_path .= DS. 'item_'.$items[$i]->id.'_field_'.$img_field->id;
		$original_path .= DS. 'original' .DS. $value['originalname'];
	} else {
		$original_path = COM_FLEXICONTENT_FILEPATH .DS. $value['originalname'];
	}
	
	$original_path  = JPath::clean( $original_path );
	
} else {
	$original_path = '';
}

NOTE above is folder path NOT url path

Name would be:

Code:

$img_field_name = 'field11';
$img_field_value = @$items[$i]->fields[$img_field_name]->value[0];

if ($img_field_value) {
  $originalname= $img_field_value['originalname'];
  // output something
}

Also this should give original file URL:

Code:

$img_field_name = 'field11';
$img_field = & $items[$i]->fields[$img_field_name];

if ( !empty($img_field->value[0]) )  {

	$value = unserialize($img_field->value[0]);
	
	if ( !empty($img_field->value[0]['is_default_value'] ) ) {
		$original_url  = JURI::root(). .'/'. $value['default_image'];
	} else if ($img_field->parameters->get('image_source') &&  ) {
		$original_url  = JURI::root().'/'. $img_field->parameters->get('dir');
		$original_url .= '/'. 'item_'.$items[$i]->id.'_field_'.$img_field->id;
		$original_url .= '/'. 'original' .'/'. $value['originalname'];
	} else {
		$original_url = JURI::root().'/'.$params->get('file_path', 'components/com_flexicontent/uploads') .'/'. $value['originalname'];
	}
	
} else {
	$original_url = '';
}
