Connecting values from PHP POST request to a variable in a python script to be executed

Message:


Take for example a simple php form such as ,


<html>  
<body>

<form action="welcome.php" method="post">
Name: <input type="text" name="name"><br>
<input type="submit">
</form>

</body>
</html>

Is it possible to POST whatever value that a user input into a python script namely app.py which has a variable named as "name" eg:-


name = #This Variable needs to be populated with the value the user inputs to the form
print(name + " "+ "is my name")

Apologies about the vague question but I am quite new to programming and would be great if someone can at least point me in the right direction if this is possible. Another doubt here is on clicking the submit button how can I trigger the python script.

In the `script.php` file, you can retrieve the value from the POST request and pass it to a Python script using `shell_exec()` function. Here's an example of how you can do this:

php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$value = $_POST["value"];
$output = shell_exec("python script.py $value");
echo $output;
}
?>


In the `script.py` file, you can access the value passed from the PHP script as a command line argument and use it in your Python code. Here's an example of how you can do this:

python
import sys

if __name__ == "__main__":
value = sys.argv[1]
# Do something with the value
print("Received value:", value)


When the form is submitted, the value entered in the input field will be passed to the Python script `script.py` as a command line argument and the Python script can then use this value in its code.
