Sorry for stupid question, but i cant figure out how to get a TV value in a snippet

Currently i have this but i doesnt return anything. The TV name: SKIN_HS_image

<?php
$tv = $modx->getTemplateVarOutput("*", 124, 1);
$results = $tv["SKIN_HS_image"];

echo "tv:".$results."";
?>

Thanks,

Aleks

Try running [tt]die(var_dump($tv));[/tt] just after you get the output and post your results.

<?php
$tv = $modx->getTemplateVarOutput('SKIN_HS_image', 124, 1);
echo $tv;
?>

and this is what i get if i use this code in the snippet:

<?php
$tv = $modx->getTemplateVarOutput('SKIN_HS_image', 124, 1);
echo $tv;
die(var_dump($tv));
?>

results in:

Arrayarray(1) { ["SKIN_HS_Image"]=>  string(66) "http://www.domain.com:8383/assets/images/skin/hs_blackdiamond.jpg" }

so now the questions is - how to pull that image value from an array ?

got it to work... here is the code i use:

<?php
$tv = $modx->getTemplateVarOutput("SKIN_HS_image", 124, 1);

if (is_array($tv))
{
foreach ($tv as $key=>$val)
{
$out = $val;
}
}
echo $out;
?>

$tv[’SKIN_HS_image’] should be what you want (getTemplateVarOutput returns an array of one or more tv values).

Indeed,

<?php
$tvname = 'SKIN_HS_image';
$tv = $modx->getTemplateVarOutput($tvname, 124, 1);
echo $tv[$tvname];
?>

Should be all you need. You can even do some checks...

<?php
$tvname = 'SKIN_HS_image';
$tv = $modx->getTemplateVarOutput($tvname, 124, 1);
if (empty($tv))
	echo "(not set)"; // In other words, "empty"
else	echo $tv[$tvname];
?>

I forgot that passing "*" as the name returns the entire document object...

UPDATE: Blargh! I’m terrible with TVs...

i still get an array:

Arrayarray(1) { ["SKIN_HS_Image"]=> string(66) "http://www.domain.com:8383/assets/images/skin/hs_blackdiamond.jpg" }

I think that you actually want to echo $tv[’SKIN_HS_image’] .
