PHP Form calculating issue

[justsomeguy]

Is this still the code you're using for the calculations which produced the output you pasted above:

//get values from the $_post array:$totalRev = $_POST['revenue'];echo "totalRev: ".$totalRev."<br />";$vCost = $_POST['cost'];echo "vCost: ".$vCost."<br />";$overheadCost = $_POST['overhead'];echo "overheadCost: ".$overheadCost."<br />";$taxes = $_POST['taxes'];echo "taxes: ".$taxes."<br />";$otherIncome = $_POST['other']; echo "other: ".$other."<br />";//Calculate the gross profit:$gross = $totalRev - $vCost;echo "gross: ".$gross."<br />";//Calculate the net profit:$netProfit = $gross - $overheadCost;echo "netProfit: ".$netProfit."<br />";// Calculate Income after taxes:$afterTaxes = $netProfit - $taxes;echo "afterTaxes: ".$afterTaxes."<br />";// Calculate the Total Income:$totalIncome = $afterTaxes + $otherIncome; echo "totalIncome: ".$TotalIncome."<br />";

[justsomeguy]

There's a problem here, the variable names aren't using the same case:

$totalIncome = $afterTaxes + $otherIncome; echo "totalIncome: ".$TotalIncome."<br />";

One has a capital T and the other doesn't.

I'm not sure why this is so difficult. Let me try to explain with an analogy:You're dealing with a calculation here, and there are certain values that go into the calculation. You're saying that you submit the values, but the result of the calculation is still 0. We're trying to get you to verify that the values that PHP is using in the calculation are the same values that you typed into the form. We're telling you to print the values out in the PHP script so that you can verify that it's using the correct values, but apparently you're not doing that.These are the steps in debugging this problem. You can't do one step until the previous ones are complete:1. Verify the values being used in the calculation.2. Verify the calculation is correct.3. Verify the answer is being displayed correctly.Again, we're over 20 posts in and we're still stuck on step 1. If you go back to the first reply to your question, you'll see that from the beginning we've been trying to get you to verify the values that PHP is actually using. Not what you think it's using, what it is actually using. You need to print those variables out and verify that they are the correct values you typed in. Once you do that then we can move on.edit: I can see we're making progress

already past that point I know where the errors are just don't understand why everything shows in the form after calculation except gross, after taxes and net income and why net income does not add since all the other things are working. check my last post you will see i did step 1

Right, I saw that. Check my last few responses.

Check your variable names. You have several mismatched variables:Gross profit</td><td><input type="text" style="40" name="gross" value="'.$GrossProfit.'">...<input type="text" style="40" name="afterTaxes" value="'.$profitAfterTaxes.'">...

fixed those

What's the current status? Is everything working like you expect?

[thescientist]

so we've confirmed that those values are showing up in var_dump after the form has submitted?

[JimKI]

so we've confirmed that those values are showing up in var_dump after the form has submitted?

yes the only value not showing up is TotalIncome but i did notice thisarray(13) { ["revenue"]=> string(8) "20000.00" ["cost"]=> string(7) "4000.00" ["grossProfit"]=> string(0) "" ["overhead"]=> string(7) "1000.00" ["netProfit"]=> string(0) "" ["taxes"]=> string(1) "0" ["afterTaxes"]=> string(0) "" ["other"]=> string(6) "500.00" ["totalIncome"]=> string(0) "" ["submit"]=> string(9) "calculate" ["email"]=> string(0) "" ["emailCc"]=> string(0) "" ["name"]=> string(0) "" } Revenue: 20000.00where ever it is string(0) it does not show up in the form what does these numbers mean and why do they have zero in them do I need to a $_POST to make the others work but Net Profit did not need this. what am I missing

[JimKI]

do i need to have variable for Gross profit, After Taxes and Total Income

[thescientist]

the way to read this in pieces:

array(13)

says you have 13 members in the array

["revenue"]=> string(8) "20000.00"

tells you that member revenue is of type string which has 8 characters in it. (most languages treat strings like an array). This reading convention can be applied to all the other members, i.e. cost, overhead, etc.Now if one of those is coming over as an empty string, like:

["grossProfit"]=> string(0) ""

this means that $_POST has a member called grossProfit, but it doesn't have a value. Are you sure you input a value for these?

[thescientist]

do i need to have variable for Gross profit, After Taxes and Total Income

well, if its empty in var_dump, that means that's what the form is submitting. that's why we do var_dump at the beginning so we know the values of everything submitted before running off and doing calculations.

[JimKI]

But we did not need to do that for Net Profit it just has the same code as the others and it works?

[JimKI]

thanks guys for all the help sorry it took so long but everything works fine thank again so much.Jim
