PHP within HTML not working using Flask

Question

I have just recently started playing around with Flask and have no previous html/php experience, so please forgive me if this is naive!

I'm trying to use some php within an html file to improve a webapp I've built, but cannot even get the simplest test case to work. For example, take a test case from this site:

--test_app.py--

import flask
app = flask.Flask('flask_test')

@app.route('/')
def test():
    return flask.render_template('test.html')

if __name__ == '__main__':
    app.run()

--templates/test.html--

<html>
<head></head>
<body>
<ul> 
<?php for($i=1;$i<=5;$i++){ ?>
<li>Menu Item <?php echo $i; ?></li> 
<?php } ?>
</ul> 
</body>
</html>

--expected output--

Menu Item 1
Menu Item 2
Menu Item 3
Menu Item 4
Menu Item 5

--actual output--

Menu Item

If there an inherent incompatibility with Flask? Am I forgetting to include something (either on the python/flask side or the html/php side) that will make it all work together?

Thanks!

have you try to change your template to test.php instead of test.html? — am05mhz

hmm, is there any reason to use PHP with flask? as flask already support its own template solution — am05mhz

You would not use PHP in Flask. If you want some scripting logic in your template, use something like this:

<html>
<head></head>
<body>
<ul>
{% for i in range(1,6) %}
<li>Menu Item {{ i }}</li>
{% endfor %}
</ul>
</body>
</html>

Answer to question by Matt Healy is right.

But looking at your code I seem problem it should be like this

<ul> 
 <?php 
    for($i=1;$i<=5;$i++){ 
      echo "<li>Menu Item ".$i."</li>"; 
    } 
 ?>
</ul>

And make sure you have .php as the file extension. Because Php will not run in HTML file.

The PHP interpreter does not work the way you want to use it. You are calling the HTML (template) file from within a flask app, thus not using the PHP interpreter. You best stick to PHP with supportet templating eg. smarty, or go for Pythonic. Trying mixing the two is a bad idea.
