copied!<p>You need to create a variable whose value is <code>{$testVariable_123}</code><br> Then you can call <code>{eval}</code> on it.</p> <p>The problem is, I couldn't find a way to do this in a good manner.<br> Everything that looks reasonably good doesn't work and the options that work are ugly.</p> <p>Maybe you'd consider some changes in your application design?</p> <p>Here's what I managed to get working:</p> <pre><code># file.php: $smarty->assign("autoValue", 123); $smarty->assign("testVariable_123", "foo"); //Option 1 $smarty->assign("anotherValue", "{\$testVariable_123}"); //Option 2 $smarty->assign("rb", '}'); // Hack to get the right bracket } withou Smarty parsing it. //Option 3 $smarty->assign("mask", '{$testVariable_%s}'); // pass the full string_format "mask" directly from PHP # file.tpl 1) Uses the $anotherValue from PHP: Plain: {$anotherValue} Evaled: {eval var=$anotherValue} 2) Build the string on Smarty itself: {assign var="yetAnotherValue" value=$autoValue|string_format:"{\$testVariable_%s$rb"} Plain: {$yetAnotherValue} Evaled: {eval var=$yetAnotherValue} 3) Build the string using the mask from php: {assign var="enoughOfValue" value=$autoValue|string_format:$mask} Plain: {$enoughOfValue} Evaled: {eval var=$enoughOfValue} </code></pre> <p>Mostly, the problem is that Smarty won't ignore a closing bracket } or a $variable even if it's in the middle of a string. Escaping with \ doesn't work neither.</p> <p>If you try:</p> <pre><code>{assign var="yetAnotherValue" value="{\$testVariable_$autoValue}"} </code></pre> <p>it will ignore the "} at the end and consider the Smarty statement as:</p> <pre><code>{assign var="yetAnotherValue" value="{\$testVariable_$autoValue} </code></pre> <p>and it will evaluate the $testVariable even tho it was supposed to be escaped.<br> So we will end up with <code>{\123</code> as the value :(</p> <p>Everything I tried ended up stumbling on that issue. If you find a better way, please, make sure you share it here :)</p>
