Linking?

[denisetrethewey]

I found this code which makes a BMI Calculator (Form) for me however when I click on submit it takes the user back to the index page ie. domain.com/index.php. How do I change it to go to, say, domain.com/calculator.php ?  The code is below:

 

<?

 

/**

* @package Module Body Mass Index Calculator for Joomla! 1.5

* @version $Id: mod_bodymassindexcalculator.php 599 2010-03-20 23:26:33Z you $

**/

 

 

defined( '_JEXEC' ) or die( 'Restricted access' );

 

$heightcm=$_POST["heightcm"];

$weightkg=$_POST["weightkg"];

 

if ($heightcm!="" && $weightkg!="") {

 

$heightm = $heightcm / 100;

$bmi=round($weightkg / ($heightm*$heightm),1);

 

echo "Heigth, m: ".$heightm."<br />";

echo "Weigth, kg: ".$weightkg."<br />";

echo "Body Mass Index (BMI): ".$bmi."<br />";

echo "<strong>";

 

if ($bmi<16.5) {echo "Severely Underweight</strong><br />";}

if ($bmi>=16.5 && $bmi<=18.4) {echo "Underweight</strong><br />";}

if ($bmi>=18.5 && $bmi<=24.9) {echo "Normal</strong><br />";}

if ($bmi>=25 && $bmi<=29.9) {echo "Overweight</strong><br />";}

if ($bmi>=30 && $bmi<=34.9) {echo "Obese Class I</strong><br />";}

if ($bmi>=35 && $bmi<=39.9) {echo "Obese Class II</strong><br />";}

if ($bmi>=40) {echo "Obese Class III</strong><br />";}

echo "<br />";

 

}

 

 

$domain = $_SERVER['HTTP_HOST'];

$path = $_SERVER['SCRIPT_NAME'];

$queryString = $_SERVER['QUERY_STRING'];

$url = "http://" . $domain . $path;

$url3 = "http://" . $domain . $_SERVER['REQUEST_URI'];

$mystring1="?";

$s1=strpos($url3,$mystring1);

if($s1==0) {$url2=$url3;}

if($s1!=0) {$url2=substr($url3,0,$s1);}

$path = $url2;

 

//1 foot = 0.3048 meters

//1 inch = 2.54 centimeters

//1 pound = 0.45359237 kilograms

 

$n1=230;

 

 

echo "<table style=\"width: 100%\" cellspacing=\"0\" cellpadding=\"0\" align=\"center\"><tr><td valign=\"top\">";

//echo "<h3>BMI Calculator</h3>";

echo "<form action=\"".$path."\" method=\"post\" >";

echo "<strong>Height</strong><br />";

echo "<select name=\"heightcm\" >";

for ($i=30; $i<=$n1; $i++){ echo "<option value=\"$i\">".$i." cm / ".floor($i / 30.48)." ft ".round(($i-(floor($i / 30.48)*30.48)) / 2.54, 1)." in </option>";}

echo "</select>";

echo "<br />";

echo "<strong>Weight</strong><br />";

echo "<select name=\"weightkg\" >";

for ($i=30; $i<=$n1; $i++){ echo "<option value=\"$i\">".$i." kg / ".round($i / 0.45359237,2)." pounds </option>";}

echo "</select>";

echo "<br />";

//echo "<input name=\"searchterm\" type=text size=\"27\" class=\"ns1\">";

echo "<br />";

echo "<input type=\"submit\" value=\"Calculate\" name=\"B1\">";

echo "</form><br />";

change your form action

[denisetrethewey]

Thanks so much for replying!  I did try that but I'm a little clueless and I don't really understand the variables nor mess anything up. What would I change it to?

The easiest way is to name that file calculator.php, and everything works.

But you should be able to just remove the path and would execute same page.

 

This is your line

echo "<form action=\"".$path."\" method=\"post\" >";

 

So make it this

echo "<form action='' method=\"post\" >";

 

Or the complete with just the file as the post location value

<?php
$heightcm=$_POST["heightcm"];
$weightkg=$_POST["weightkg"];

if ($heightcm!="" && $weightkg!="") {

$heightm = $heightcm / 100;
$bmi=round($weightkg / ($heightm*$heightm),1);

echo "Heigth, m: ".$heightm."<br />";
echo "Weigth, kg: ".$weightkg."<br />";
echo "Body Mass Index (BMI): ".$bmi."<br />";
echo "<strong>";

if ($bmi<16.5) {echo "Severely Underweight</strong><br />";}
if ($bmi>=16.5 && $bmi<=18.4) {echo "Underweight</strong><br />";}
if ($bmi>=18.5 && $bmi<=24.9) {echo "Normal</strong><br />";}
if ($bmi>=25 && $bmi<=29.9) {echo "Overweight</strong><br />";}
if ($bmi>=30 && $bmi<=34.9) {echo "Obese Class I</strong><br />";}
if ($bmi>=35 && $bmi<=39.9) {echo "Obese Class II</strong><br />";}
if ($bmi>=40) {echo "Obese Class III</strong><br />";}
echo "<br />";

}


$domain = $_SERVER['HTTP_HOST'];
$path = $_SERVER['SCRIPT_NAME'];
$queryString = $_SERVER['QUERY_STRING'];
$url = "http://" . $domain . $path;
$url3 = "http://" . $domain . $_SERVER['REQUEST_URI'];
$mystring1="?";
$s1=strpos($url3,$mystring1);
if($s1==0) {$url2=$url3;}
if($s1!=0) {$url2=substr($url3,0,$s1);}
$path = $url2;

//1 foot = 0.3048 meters
//1 inch = 2.54 centimeters
//1 pound = 0.45359237 kilograms

$n1=230;


echo "<table style=\"width: 100%\" cellspacing=\"0\" cellpadding=\"0\" align=\"center\"><tr><td valign=\"top\">";
//echo "<h3>BMI Calculator</h3>";


echo "<form action='calculator.php' method=\"post\" >";
//or even this
//echo "<form action='http://domain.com/calculator.php' method=\"post\" >";

echo "<strong>Height</strong><br />";
echo "<select name=\"heightcm\" >";
for ($i=30; $i<=$n1; $i++){ echo "<option value=\"$i\">".$i." cm / ".floor($i / 30.48)." ft ".round(($i-(floor($i / 30.48)*30.48)) / 2.54, 1)." in </option>";}
echo "</select>";
echo "<br />";
echo "<strong>Weight</strong><br />";
echo "<select name=\"weightkg\" >";
for ($i=30; $i<=$n1; $i++){ echo "<option value=\"$i\">".$i." kg / ".round($i / 0.45359237,2)." pounds </option>";}
echo "</select>";
echo "<br />";
//echo "<input name=\"searchterm\" type=text size=\"27\" class=\"ns1\">";
echo "<br />";
echo "<input type=\"submit\" value=\"Calculate\" name=\"B1\">";
echo "</form><br />";
