field select elements - How to get value for an index was created by Myl

Hi,

Maybe someone can help me..
I need to call the value from a "select field" in an item template.

I have created a select field with this field element:
1::name1%% 2::name2%% 3::name3%% 4::name4

I have selected in item element name2.

Now I need to stamp his value: 2.

I try this:
<?php echo $this->fields->value ?>

and the result is "Array".

How I can find the selected value? (In this case "2")

[I use Joomla 1.7 and the last beta release of Flexicontent (v2.0 beta5 r960)]

Thank you

You can use this:
it will give you the values of the field in an indexed array e.g.
echo $field_elements_arr[2];

put the name (not the label) of the field in the first row, the last line prints the values,

Code:

<?php
	$field_name = 'selsimple1';
	$field_elements = $this->fields[$field_name]->parameters->get( 'field_elements' ) ;
	
	$field_elements_strings = explode("%% ", $field_elements);
	$field_elements_arr = array();
	
	foreach ($field_elements_strings as $field_element_str) {
		list ($f_index, $f_value) = explode("::", $field_element_str);
		$field_elements_arr[$f_index] = $f_value;
	}
	echo "<pre>"; print_r($field_elements_arr); echo "</pre>";
?>

Thankyou for your answer.
This is what I have after using you're code:

Array
(
[1] => name1
[2] => name2
[3] => name3
[4] => name4
[5] => name5
)

If I use:
echo $field_elements_arr[2]

I have:
name2

And is correct but I need that:
When in backend someone select "name2" in frontend I need only the number 2 because I need to use it for other thing..

How I can do this?

Another thankyou and sorry for my bad english

Code:

<?php
	$field_name = 'selsimple1';
	//$field_name = $field->name;  // IF you use a position
	$field_value0 = $this->fields[$field_name]->value[0];

	//... the previous code i gave you

	echo $field_elements_arr[$field_value0]."<br>";

	//... for many values:
	foreach($this->fields[$field_name]->value as $val) {
		echo $field_elements_arr[$val]."<br>";
	}
?>
