问题:

I want to assign the value obtained from the concatenation of these two variables with a string.

{assign var="url" value="{$WS_PATH}aircraft_images/{$images[i].image}"}

Please let me know how can we do this in smarty.

回答1:

One of these should work:

{assign var="url" value=$WS_PATH|cat:"aircraft_images/"|cat:$images[i].image}

{assign var="url" value="`$WS_PATH`aircraft_images/`$images[i].image`"}

I am not sure if the $images[i].image will be parsed correctly, you may have to {assign} it to another variable first

You've used assign properly.

A simplified example could look like this:

yourphpfile.php:

$tpl = new Smarty;
$tpl->assign('var1','Hello');
$tpl->assign('var2','World');
$tpl->display('yourtemplate.tpl');

yourtemplate.tpl:

...
<body>
{assign var="url" value="{$var1} - and - {$var2}"}
{$url}
</body>

...will result to the output:

Hello - and - World

such an expression will do the trick:

{$product1_photo = "{$smarty.const.IMG_URL}/{$pInfo.PhotoName}"}
