if if no longer works

Anon

I have a simple if statement to test the value of a variable. It has stopped working and I have no idea why. Please review the following code fragement and output and help me out of a tough spot.

Thanks

HERE IS THE CODE:

//Begin Test
if($testmode == 1)
{
print("<BR><font color=red
size=+2>TEST::t_minbid =
$t_minbid</font>");
}
//End Test

//Begin Test
if($testmode == 1)
{
print("<BR><font color=red
size=+2>TEST::aucbid =
$aucbid</font>");
}
//End Test

if ($aucbid < $t_minbid)
{
//Begin Test
if($testmode == 1)
{
print("<BR><font color=red
size=+2>TEST:: or here</font>");
}
//End Test

$toolow = 1;
}

if ($toolow)
{
echo "<h3>Bid too low.</h3>";
echo "<p>Sorry, that bid is too low.
Bids must meet or exceed the ";
echo "listed minimum bid.

Please try again. ";
exit;
}

AND HERE IS THE OUTPUT:

<font color=red size=+2>TEST::t_minbid = 110</font>
<BR>
<font color=red size=+2>TEST::aucbid = 110</font>
<BR><font color=red size=+2>TEST:: or here</font><h3>Bid too low.</h3>
<p>
Sorry, that bid is too low.

Bids must meet or exceed the listed minimum bid.

Please try again.

In my previous message, the forum tried to parse my code and made a mess of it. I will try again and see if I have better results.

HERE IS THE CODE: (with the offending html tags removed...

print("TEST::t_minbid = $t_minbid");

print("TEST::aucbid = $aucbid");

if ($aucbid < $t_minbid)
{
print("TEST:: or here");}
$toolow = 1;
}

if ($toolow)
{
echo "Bid too low.";
echo "Sorry, that bid is too low.

Bids must meet or exceed the ";
echo "listed minimum bid.

Please try again.";

exit;
}

AND THE OUTPUT:

TEST::t_minbid = 110
TEST::aucbid = 110
TEST:: or here

Bid too low.
Sorry, that bid is too low. Bids must meet or exceed the listed minimum bid. Please try again.

I've just tried your script and the Output was only

TEST::t_minbid = 110
TEST::aucbid = 110

Here the script I used (perhaps the problem corrected itself when I copied it 🙂...

$t_minbid = 110;
$aucbid = 110;
print("TEST::t_minbid = $t_minbid");

print("TEST::aucbid = $aucbid");

if ($aucbid < $t_minbid)
{
if($testmode == 1)
{
print("TEST:: or here");
}
$toolow = 1;
}

if ($toolow)
{
echo "Bid too low.";
echo "Sorry, that bid is too low.
Bids must meet or exceed the ";
echo "listed minimum bid.
Please try again.";

exit;
}

Where did you get your two numbers? If this code is correct, your output is very odd. The only thing I can think of is maybe some floating point precision error.

Maybe 110 is really 109.99999999 in one and 110.000000001 in the other???

I can see a problem like this happening in C++, but not in PHP, since most variables are strings or integers...

Does your code work if you put a literal number in like Goldeneye did?

Thanks John, the problem was a loss of precision due to a floating point problem. I am nopt sure why that did not appear when I printed the the variables, but I was able to resolve the problem with the round()

Thanks again,
