Question

can you please help me how to add a link to php code.

Thing is that I am using a BMI calculator for wordpress and I want to add a link next to a result number.

I know html, but not php...

one slip of a php code where I want to have a link is:

    $theme = $attrs['theme'] ?: 'default';
    $resultText = $attrs['result'] ?: 'Your BMI is %bmi% ';
        $resultText = str_replace('%bmi%', '<span class="bmi-number"></span>', $resultText);

-> I would like to have a link right next to the bmi result number -> 'Your BMI is %bmi% '

Is it possible to do that?

Thanks in advance

Answer 1

尝试这样做

$BMI = 123;
$resultText = "Your BMI is <a href='YOUR_LINK_HERE'>".$BMI."</a>";

Answer 2

$BMI = 'click here'; //There can be some code here
$resultText = "Your BMI is <a href='http://your_link.com'>$BMI</a> ";
echo $resultText;

感谢大家的答案...但是％bmi％是某种变数，因为在页面上我放了一个短代码：
[bmi theme =＆＃34;默认＆＃34; heightPlaceholder =＆＃34;身高＆＃34;提交=＆＃34;计算＆＃34;结果=＆＃34; BMI无效％bmi％＆＃34;]

这个％bmi％从表单中计算...以您放置体重和身高的形式而不是得到答案，您可以在测试页面上查看：http://legionargym.si/testna-stran/

向下滑动并查看计算您的BMI
