I need to let the code below to stop directly execute the code without button click. I want the function to run when button is click on it. Thanks for the help
<html>
<head>
<script language="javascript" type="text/JavaScript">
{
function popup() {
<?php echo shell_exec('sh bash_test.sh') ?>;
}
}
</script>
</head>
<body>
<input type="button" onclick="popup()" value="popup">
</body>
</html>
The only way to do this is to make a form or change something in url like window.location and check vars. You cannot mix Javascript with PHP like that
script.php:
<html>
<head>
<script language="javascript" type="text/javascript">
function popup(){
window.location = 'script.php?run=shell';
}
</script>
</head>
<body>
<input type="button" onclick="popup()" value="popup">
<?php
if(isset($_GET['run']) && ($_GET['run'] == 'shell')){
echo shell_exec('sh bash_test.sh');
}
?>
</body>
</html>
! wrongly there, modified. And you should know you cannot execute a shell script if you don't have permissions.your html is invalid. your </script> tag should be before the </head> tag
if you really want to execute it only when you press the button then you should consider using ajax or to use a <form>
alert('<?php echo shell_exec('sh bash_test.sh') ; ?>');
You can do that using ajax-request, for example, with jquery:
<html>
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script language="javascript" type="text/JavaScript">
{
function popup() {
$.post('someScript.php');
}
}
</script>
</head>
<body>
<input type="button" onclick="popup()" value="popup">
</body>
</html>
In "someScript.php" you can put command
shell_exec('sh bash_test.sh');
