HELP with functions and calculations!!

[bluez26]

Hey I'm new to php ... obviously lol ... anyway I'm having a hard time getting this code to work. It's for a hw assignment in my class and we have to use a function to calculate a part of a form. Every time I try to incorporate this function/call it or whatever I end up getting a blank page when I click the submit button on the page. Someone please help me! I am completely lost here.

 

function HourlyRate($_GET["THrs"], $_GET["Rate"]){

$TotHrs = $_GET["THrs"];

$PRate = $_GET["Rate"];

If($TotHrs <= "40") $HRate = ($TotHrs * $PRate);

else

$HRate = ("40" * $PRate) + (($TotHrs - "40") * ($PRate * "1.5"));

echo $HRate;

}

 

echo "<p>Employee Last Name: ", $_GET["EmpName"], "</p>";

echo "<p>Employee SSN: ", $_GET["EmpSSN"], "</p>";

echo "<p>Employee Status: ", $_GET["EmpStat"], "</p>";

echo "<p>Week Beginning: ", $_GET["BDate"], "</p>";

echo "<p>Hours Worked: ", $_GET["THrs"], "</p>";

echo "<p>Pay Rate: ", $_GET["Rate"], "</p>";

echo "<p>Gross Pay: ";

If ($_GET["EmpStat"] == "Exempt") echo $_GET["THrs"] * $_GET["Rate"]

else HourlyRate($_GET["THrs"], $_GET["Rate"]);

 

 

Please help!

Can you post the code for the form?  If you are using post method in the form, then you must check $_POST instead of $_GET (or $_REQUEST, which includes both methods)

[phpSensei]

Post your Form

 

Try

 

function HourlyRate($thrs,$rate){
  $TotHrs = $thrs;
  $PRate = $rate;
  If($TotHrs <= 40){ 
         $HRate = ($TotHrs * $PRate);
           } else {
                  $HRate = (40 * $PRate) + (($TotHrs - 40) * ($PRate * 1.5));
            }  return $HRate;
         }

  $hrate = HourlyRate($_GET['THrs'],$_GET['Rate']);
echo $hrate;

It still won't work

 

I changed my function like you have it there and put this in as part of the IF statement and it still gives me a blank page...

 

If ($_GET["EmpStat"] == "Exempt") echo $_GET["THrs"] * $_GET["Rate"]

else $hrate = HourlyRate($_GET['THrs'],$_GET['Rate']);

 

echo $hrate;

 

 

I'm not using any $_POST or anything like that in my form, just the "get" method.

OH scratch that.. I forgot the brackets.. lemme try again

[bluez26]

Still not working  ???

i think we still need your FORM code (submittion code).

 

I think the problem (without the form code) is that your trying to use $_GET variables (these variables are in the browser URL as a "Query String")

 

Most Form use "Method=post", therefor you should change all of your $_GET vars to $_POST vars as btherl explained earlier.

Well my teacher left us the source code for the form and he's using the get method but here's what i have:

 

<form method="get" action="Proj2.php">

<table width="600px"><tr><td>

<strong>Employee Name:</strong>

</td><td colspan="3">

<input name="EmpName" type="text" style="width:300px;" />

</td></tr>

<tr><td>

<strong>Employee SSN:</strong>

</td><td>

<input name="EmpSSN" type="text" style="width:100px;" />

</td><td>

<strong>Employee Status:</strong>

</td><td>

<input name="EmpStat" type="radio" value="Exempt" checked="checked" style="border:0px;" /> Exempt    

<input name="EmpStat" type="radio" value="Hourly" style="border:0px;" />Hourly

</td></tr>

<tr><td>

<strong>Week Begining:</strong>

</td><td>

<input name="BDate" type="text" style="width:100px;" />

</td><td>

<strong>Total Hours:</strong>

</td><td>

<input name="THrs" type="text" style="width:100px;" />

</td></tr>

<tr><td>

<strong>Pay Rate:</strong>

</td><td>

<input name="Rate" type="text" style="width:100px;" />

</td></tr>

<tr><td colspan="4">

<input name="reset" type="reset" value="Reset" />    

<input name="submit" type="submit" value="Submit" />

</td></tr>

</table>

</form>

try

 

<?php
function HourlyRate($thrs,$rate){
  $TotHrs = $thrs;
  $PRate = $rate;
  If($TotHrs <= 40){ 
        $HRate = ($TotHrs * $PRate);
          } else {
                 $HRate = (40 * $PRate) + (($TotHrs - 40) * ($PRate * 1.5));
            }  return $HRate;
        }




echo "<p>Employee Last Name: ", $_POST["EmpName"], "</p>";
echo "<p>Employee SSN: ", $_POST["EmpSSN"], "</p>";
echo "<p>Employee Status: ", $_POST["EmpStat"], "</p>";
echo "<p>Week Beginning: ", $_POST["BDate"], "</p>";
echo "<p>Hours Worked: ", $_POST["THrs"], "</p>";
echo "<p>Pay Rate: ", $_POST["Rate"], "</p>";
echo "<p>Gross Pay: "; 
     If ($_POST["EmpStat"] == "Exempt"){ 

echo $_POST["THrs"] * $_POST["Rate"];


}
        else{  

$hrate = HourlyRate($_POST['THrs'],$_POST['Rate']);
echo $hrate;


}

 ?>

FYI your problem i believe was your Function had syntax errors, which php ended the script, it seems your php installation doesn't "display_errors".

[uniflare]

try putting

 

ini_set('display_errors', 1)

 

at the top of your script

[bluez26]

Yeah I'm not sure why the get method won't work for me and will for my teacher's script but the post one is working perfectly. Thank you all for your help I really appreciate it!
