PLEASE HELP me: Health Cover Calculator

swannette

I have to calculate how much health cover will cost when the person chooses their cover from a radio button and the extras they require from checkboxes. I have the following code already done and not sure if it will work. I need to do the calculating as follows.

Individual Cover = $1200
Couples Cover = $2500
Family Cover = $3200

Once chosen the extras options are available from a checkbox ie;

Physiotherapy
Dental
Optical

each extra costs $50 dollars and for a couple it is double that and a family is triple that amount.

How do I fix this code to make it work? I'm going crazy!!!! PLEASE, PLEASE, PLEASE HELP ME!!!!

I'm just wondering if anyone has a solution for this please. Am I heading in the right direction?😕

looks like the right direction, not really sure what you are asking however. you would get a better response with a specific question.

Hi swannette,

Are you sure you didnt got any errors while running this. Because you have an error in the below section.

//DISPLAY THE TYPE OF COVER SELECTED

if (array_key_exists('individual', 'couple', 'family')){
echo "<p>Hospital cover:</p>";
$cover_array = ('individual' || 'couple' || 'family');
echo $cover_array;
}
else {
$cover = 'Not selected';
}

Please check the syntax for array_key_exists. your missing the array argument and the syntax is wrong.

Please check your code and let us know and we`ll solve this step by step 🙂

Best regards,
Niroshan

yeah, I totally redid the coding and got it working. The only thing is I'm not sure how to stop the form processing when an error is detected in the form.
eg: if the user fails to fill the form out correctly, I display an error message, but it still continues processing the other areas. I need the form to stop processing after it informs the user to go back and fill in required fields. I hope that makes sense!!

I have used this code for the error, and even though it works, it is not stopping at the point of where the error occurred and is still continuing with the rest of the form.

//IF ERRORS HAVE BEEN DETECTED, DISPLAY THE ERROR MESSAGES.

	if ($cover == FALSE) 
	{
		echo "<p>You must choose a Hospital Cover.<br />\n";
		echo $error;
		echo "Please click the browser's back button to try again.</p>\n";

I need extra error code to stop the form processing until the user correctly enters data?

Cheers

dagon

exit(); at a guess but with out seeing the code its just a guess.

swannette

Where do I place the exit() code?

dagon

after you output the error perhaps.

swannette

I tried that and it came up with a blank screen. I need it to tell the user that they have entered wrong data and they need to press the back button and try again, but I also need it to stop calculating the rest of the form at the point where the error occurs.

dagon

if you put the exit after the echo, its not possible, but why not post some code, its like playing darts in the dark, without seeing your code

swannette

Here it is.

use the boards php tags.

I don't know what you mean???

Silly question, but how do I do that?

See this vBulletin FAQ to learn how to use the bbcode tags properly. In the mean time, I've edited your posts to include these tags.

Hi swannette,

If you look at your code closer you`ll undestand why it go pass the error and display everything even though you encounter an error / s. take a look at this code of yours,

if ($error != "") 
{ 
            echo "<p>Your data contains some errors.<br />\n"; 
            echo $error; 
            echo "Please click the browser's back button to try again.</p>\n"; 
}

Here your catching the error thats fine. but do you tell the PHP parser to stop after that. No right. so what happen here is that PHP parser check the $error variable against your condition and if error occurred the condition becomes true so it goes inside and then comes out and follow up with the rest of the code below.

So to over come this and stick to your objective (which is stop when ever error occurred and alert that to user) we can do 2 things,

we can use exit() function like dagon mentioned.

if ($error != "") 
{ 
            echo "<p>Your data contains some errors.<br />\n"; 
            echo $error; 
            echo "Please click the browser's back button to try again.</p>\n"; 
            exit();
}

Put the rest of the code inside else condition

if ($error != "") 
{ 
            echo "<p>Your data contains some errors.<br />\n"; 
            echo $error; 
            echo "Please click the browser's back button to try again.</p>\n"; 
} 
else
{
     echo "<p>First Name: ".$first_name."<br />"; 
     echo "<p>Last Name: ".$last_name."<br />"; 
     echo "<p>Phone: ".$phone_number."<br />"; 

  //ADD COSTS TO EACH COVER TYPE 

 $cover=$_POST['cover']; 
 $covervalue=0; 

 /* rest of the code .........................*/

}

Hope this is clear enough for you.

Best regards,
Niroshan
