Setting template variable as PHP variable in snippet

20 Posts

Hello,

I'm trying to set a snippet variable to a modx template variable which I can use in a function. In this case my template variable would be the string 'Brandname'. Eventually I am trying to write a function using a switch statement that will dynamically replace content based on the template variable string. Right now I can't get the template variable to be read as a string. Here's what's not working:

$myBrand = '[[*Brand]]';

if ($myBrand == 'Brandname'){
       echo 'hello';
}

But if I simply put:

echo $myBrand;

OR

var_dump($myBrand);

Then I will see that $myBrand has been set to 'Brandname' and am thus a little confused as to why it gets represented in the echo statement and var_dump but not in my simple 'if' statement.

I am running ModX 2.2.8

Thanks for your help!

well,

$myBrand = '[[*Brand]]';
echo $myBrand;

echoes just

[[*Brand]]

and the MODX - parser replaces it with the value of the TV.

there are two ways to get the value into your snippet:

[[yourSnippet? &myBrand=`[[*Brand]]`]]

Than you can use it inside your snippet with

$output = '';
if ($myBrand == 'Brandname'){
       $output = 'hello';
}

return $output;

or better:

$myBrand = $modx->getOption('myBrand',$scriptProperties,'');
$output = '';

if ($myBrand == 'Brandname'){
       $output = 'hello';
}

return $output;

Or you use the API to get the TV - value with

$myBrand = $modx->resource->getTVValue('Brand');
if ($myBrand == 'Brandname'){
       $output = 'hello';
}
return $output;

I know this looks wrong, but that should be $modx->resource->getTVValue() (three caps).

I'm allways not sure about the correct casing and need to look into modresource.class.php before using it.

corrected it above.

The only reason I know is that I had it wrong in my book and had to fix it in a bunch of places. wink
