Hi Experts,
I need some help with a small web front end (PHP) to execute my many python scripts and display the output in the webpage, the problem I cannot get my head around is how i execute the script and map this to the output display.

My small uncompleted example code is below and any help would be greatly appreciated.

cheers

<?PHP
 
$in_scripts     = $_POST['scripts'];
?>
<html><head><title>TEST PHP Front end for python scripts</title>
</head><b>Front end for running python scripts<b><body>
<form action='' method='post'>
</label><br />
 
<?php
        $scripts = array (
                        "pythonscript1",
                        "pythonscript2",
                );
?>Python scripts:&nbsp;
 
        <select name="scripts" id="scripts" value=''>
                        <?php
                                while($nt=each($scripts))
                                {
                                        if ($nt[1] == $in_scripts)
{$scripts_checked="selected";} else {$scripts_checked="";}
                                        echo "<option value='$nt[1]'
$scripts_checked>$nt[1]</option><BR>";}
?>
        </select>
</td>
<BR>
<input type="submit" value="Execute script" />
</form>
<?php
 
if(isset($_REQUEST['SIPT'])) {
  echo <<<END
<pre>Script output 
END;
 
  if ($in_scripts == "pythonscript1") { echo "<BR>pythonscript1";}
    if ($in_scripts == "pythonscript2") { echo "<BR>pythonscript2";}
} 
?>
</body>
</html>

Hi,

I think you want this:

From the following you get the idea.

Use exec() for running python scripts.

Hope this will help you.

Regards
<?PHP
 
$in_scripts     = $_POST['scripts'];
?>
<html><head><title>TEST PHP Front end for python scripts</title>
</head><b>Front end for running python scripts<b><body>
<form action='' method='post'>
</label><br />
 
<?php
        $scripts = array (
                        "pythonscript1",
                        "pythonscript2",
                );
?>Python scripts: 
 
        <select name="scripts" id="scripts" value=''>
                        <?php
                                while($nt=each($scripts))
                                {
                                        if ($nt[1] == $in_scripts)
{$scripts_checked="selected";} else {$scripts_checked="";}
                                        echo "<option value='$nt[1]'
$scripts_checked>$nt[1]</option><BR>";}
?>
        </select>
</td>
<BR>
<input type="submit" value="Execute script" />
</form>
<?php
 
  if ($in_scripts == "pythonscript1") { 
echo "<BR>pythonscript1";
exec("myprogram.py");
}
    if ($in_scripts == "pythonscript2") { 
echo "<BR>pythonscript2";
exec("myprogram1.py");
}
 
?>
</body>
</html>

Hi Shobinsun,
Thanks for this but it does not display the output through the webpage, I have made a few modification and get some output but it's not all of it, could you take a look?

cheers

<?PHP
 
$in_scripts     = $_POST['scripts'];
$output = exec("/var/www/testmsan.py");
$output2 = exec("/var/www/testmsan2.py");

</head><b>Front end for running python scripts<b><body>
<form action='' method='post'>
</label><br />
 
<?php
        $scripts = array (
                        "pythonscript1",
                        "pythonscript2",
                );
?>Python scripts:

Just try using system() instead of exec() -- it outputs the results by default.  Depending on your output, you may also want to stick it in a <pre>...</pre> block to make sure the output isn't interpreted as HTML if it is not supposed to be.

a few pointers hope they help
1) import cgi into your scripts,this way you can directly return the output as desired
2) convert your scripts in web services
