HTML按钮和php文件

Question

I have a website that I created and I need to have a button link to a php file for it to execute a python script. My problem is that when you click the button the script does not execute. This is what I have so far, anything will help! The php file is called minecraft.php and the python script is called py-mine.py.

<?php
$output = shell_exec('/var/www/html/py-mine.py');
?>

and a section of my html for the button:

<a href="minecraft.php">
<button class="bkg-navy-light border-hover-navy-light color-white color-hover-navy-light no-margin-left" ></a>
    <span class="icon-upload"></span>
        Minecraft
    </button>
<input type="submit" value="Button3" class="form-submit button medium bkg-black bkg-hover-turquoise color-white color-hover-white">

Answer 1

You should properly structure the HTML code:

You can use a hyperlink:

<a href="minecraft.php">A link to the PHP page</a>

OR

Use a button:

<form action="minecraft.php" method="GET">
    <button class="bkg-navy-light border-hover-navy-light color-white color-hover-navy-light no-margin-left" type="submit">
        <span class="icon-upload"></span>
        A button to the PHP page
    </button>
</form>

In your current code you used mix of both with wrong syntax structure.

Make sure you use one option.

Also, your php shell_exec should call a shell command, which in your case should be python:

<?php
$output = shell_exec('python /var/www/html/py-mine.py');
?>
