单击按钮运行php函数 [英] Run php function on button click

问题描述

我要在单击按钮时运行php函数.例如:

I want to run a php function on button click. for eg :

<input type="button" name="test" id="test" value="RUN"  onclick="<?php echo testfun(); ?>" /><br/>

<?php

function testfun()
{
   echo "Your test function on button click is working";
}

我的问题是，当我这样做时，我没有得到想要的预期输出.请给我最好的解决方案，以便在按钮单击时运行php函数，无论它是简单的button还是submit.

My question is that when I do this I don't get the expected output I was looking for. Please give me the best solution for this to run a php function on button click whether it is a simple button or submit.

推荐答案

我尝试了William的代码，谢谢兄弟.

I tried the code of William, Thanks brother.

但是它不能用作简单的按钮，我必须使用method ="post"添加表单.另外，我必须写提交而不是按钮.

but it's not working as a simple button I have to add form with method="post". Also I have to write submit instead of button.

这是我的下面的代码.

<form method="post">
    <input type="submit" name="test" id="test" value="RUN" /><br/>
</form>

<?php

function testfun()
{
   echo "Your test function on button click is working";
}

if(array_key_exists('test',$_POST)){
   testfun();
}

?>
