For Loop

Hamsterpants

HI All,

Ok what I am trying to do is display an image to the number that a value represents. So for example if the var = 5 then the image needs to display 5X. The image is a star and represents a rateing.

I have tried to use a for loop, but cant seem to get it to work correctly. Please can someone have a look at it and let me know where I am going wrong:

for ($rate>1; $rate<=10; $rate++ )
{
print "<img src=\"../images/rate.gif\">";
}

The for works like this:

for(initial, condiction, incresement)

so, a fix of your code:

for ($rate = 1; $rate<=10; $rate++ ) 
{ 
print "<img src=\"../images/rate.gif\">"; 
}

And that should work.

Try this

for ($=0; $i<$rate; $i++ )
{
print "<img src=\"../images/rate.gif\">";
}

Thanks for the promt reply.
I tried the first suggestion by PESTS, but that didn't work.
The second solution by HalfaBee, does seem to be giving the correct results....not 100% sure why, but it is.

Thanks

I can tell you why it works.
If $rate is a value between 1-10
It counts $rate number of times.

There is a little bug in the code HalfaBee posted

replace

for ($=0; $i<$rate; $i++ )

for ($i=0; $i<$rate; $i++ )
