Looped: Adding values on looped rows

monk_builder

Greetings Newbies:

Ok, this thing is almost there : )

This part is supossed to:

create rows dynamically through a loop (done that)
remember the user-entered-values while the form posts to itself
I know it should be done by echoing the amount entered into the field but haven't figured out the syntax for that.
provide a "Total" (addition of values entered in each row of all 3 rows.) (kinda tricky since the rows are looped). I know i'm supossed to append an addition for every iteration --haven't been able to do that.

You may laugh but I worked on this all night long last night. (no kidding).
I understand the concept and know what I should do I just don't know the appropiate syntax needed.

This is my second week trying to figure out PHP, so excuse the mess.

Any constructive tips would be apreciated.

Thank you in advance.

<form method="GET" action="success.php">


<?php

// THERE ARE TWO CELLS PER ROW
// TOTAL OF 3 ROWS - HERE'S THE LOOP TO CREATE THEM

for ($i = 1; $i <= 3; $i++)
{


// VARS FOR  SOURCE CELL

$source_name = 'source'."$i";

$source_value_=$HTTP_POST_VARS['amount'][$i];




// VARS FOR  AMOUNT CELL

$amount_name = 'amount'."$i";

$amount_value_=$HTTP_POST_VARS['amount'][$i];





//.HTML. CODE FOR TABLE
// CODE FOR SOURCE CELL

print'<tr>';

print"<td>";


//VALUE SHOULD ECHO THE SOURCE ENTERED

print "<input_type=text_name=$source_name[$i]_value='$source_value'>";

print" </td>";                   





// CODE FOR AMOUNT CELL

print"<td>";

//VALUE SHOULD ECHO THE AMOUNT ENTERED

print "<input_type=text_name=$amount_name[$i]_value='$amount_value'>";

print"</td>";




//AMOUNT VALUES SHOULD BE ADDED FOR EACH ITERATION

$total =($amount + $amount);
print "total is . $total";



} // CLOSE FOR



?>

Well, one possible issue is that your form is coded to use the GET method, but you're calling values from HTTP_POST_VARS instead of HTTP_GET_VARS....

HTH,
