[SOLVED] PHP Program Help

sgalatas · November 12, 2007

Hello Again,

I am writing a program that is supposed to accept input from a form (sports stats), verify the input, keep accepting from the form until complete, use the screen input to create an array, and then finally display the mean, mode, and median of the array.

I have taken some of your advice in previous threads. However, I'm not sure that I followed it correctly. The program is still not working.

Can someone take a look at it and let me know what's wrong and how to correct it? Please don;t be too harsh on me. I'm a beginner.

Here is what I have:

[<html>
<head>


</head>

<body>
<h1 style="text-align: center; color: navy" >Sports Stats</h1>
<form>
<fieldset>
<label for="stat">Enter Stats (Separate each stats using a comma.)</label>
<input type= "text" name= "stat"  id="stat" size="5" />
</fieldset>
<!---->
<fieldset>
<input type= "submit" name= "submit" id="submit" value= "Submit" />
<input type="reset" name="reset" value="Cancel" />
</fieldset>	

</form>

<?php

/**
* Author: Sherrie Galatas
* Date:  November 15, 2007
*  * Determine the Mean, Mode, and Median of the Array
*/



$max = 5;
$statArray = array("");

$stat = $_GET['stat'];


//echo " $stat <br />";

if ($i = 0; $i <= 5; $i++) 

if (is_numeric($$_GET['stat']) {
$stat = $_GET['stat'];

$stat = $statArray($stat);
foreach ($stat as $key => $value) {
echo "stat ($key + 1) = $value<br />";
}
}
sort($statArray);

$mean= array_sum($stat) / count($stat);
$median= $statArray[2];
function mode($data){
$temp = array_count_values($data);
asort($temp);
$mode = array();
$mode['count'] = current($temp);
$mode['value'] = ket($temp);
return $mode;
}

$mode = mode($array);
$mode_value = $mode['value'];
$mode_count = $mode['count'];	


?>




</body>

</html>

FYI, most people will put the PHP code before the HTML, only because once you start getting into Headers and Sessions, that code needs to come first.

Review some FORMS threads and see how others use ISSET on SUBMIT to see if the form has been submitted yet, and if it has to process it and if it hasn't to create it.

Also, I don't see your FORM ACTION or METHOD anywhere in your HTML.

sgalatas · November 12, 2007

When I put the form action and method in, it gives me an option to open the actual php file. When I hit open, it opens the php code.

revraz · November 12, 2007

Sounds like you don't have .php installed on your webserver then.

Make a small test.php file, put:

<?php

phpinfo();

?>

And run the test.php and see if you get a PHP info sheet. If it just tries to save the file to your PC, you don't have PHP installed or .htaccess isn't setup to use the extension.

Your code is riddled with basic errors. You really need some kind of text editor with color formatting. I suggest Notepad++.

Now, as for your code, the two lines you should look at:

<?php
//echo " $stat 
";                             //"; what's this? the // comment only comments one line

if ($i = 0; $i <= 5; $i++)     // and this? this is either a for loop or should be commented out.
?>

There are probably more, but this should start you out.

sgalatas · November 14, 2007

Oops! I put the comment marks on every line after the form to see what exactly was working. I also made a few changes. I know the form works. I'm actully using phpDeigner 2007 Professional. When I debug & Run, I get a message stating that line 33 has undefined index: stat . Line 33 is $statstring = $_GET['stat]; {

<form method="get" action="">

<?php

print_r($_GET);

$statstring = $_GET['stat'];{

}echo "$statstring";

foreach ($stat as $key => $value) {

echo "stat ($key + 1) = $value<br />";

}

}

sort($statArray);

$mean= array_sum($stat) / count($stat);

$median= $statArray[2];

function mode($data){

$temp = array_count_values($data);

asort($temp);

$mode = array();

$mode['count'] = current($temp);

$mode['value'] = ket($temp);

return $mode;

}

$mode = mode($array);

$mode_value = $mode['value'];

$mode_count = $mode['count'];

?>

</body>

</html>

That's because the first time you run your script (before submitting your form) the variable $_GET['stat'] doesn't exist. Hence your error.

revraz · November 14, 2007

Which is why most people check ISSET first

aschk · November 14, 2007

Hehe, yes indeed

sgalatas · November 14, 2007

Ok, I've made a few more changes and I finally got the program to work with the exception of fgetting the mode. It's currently giving the mean and median. But I still can not get it to calculate the mode. What am I missing?
