unique name for input checkbox.....

[Anon]

hi again

i am trying to print out an input medium in a loop (in this case i chose checkbox)
the problem is the name="" attribute
coz the # of check box is dynamically generated depending on database , i found out i have a problem associating unique name to the name=" " as in the <input type=checkbox name=" ">

is there a way out or is this impossible??

thankssss

not sure I am with you but...

if you want a unique name for every checkbox just add a variable into the loop.

ie:
<?
$x=0;
while($thisrow=$mysql_fetch_row($result)){?>
<input type="checkbox" name="box<? echo $x"?>"><br>
<? $x++; }?>

then you have box0,box1,box2 etc etc

hope that was what you meant!

hi again..

yah thats what basically i want to do
i tried ur code but there is an error.
im not sure how you put in <? into html...

anyhow yah if i have $a=box; $b=1;
is there a way to assign the value of these two into a variable (to concatenate?? is this word right?)
.. i tried out $c=$a.$b;
but it wouldn'[t work
i want $c to have value "box1"

thanks

hi

i looked all over the manual but couldn't find append command?
i remember saw it (when i dont need it)
i think it's a . operator?

but it doesn't work
i want to do the following
$a=box;
$b=1;
$c=box1; (hopefully by combining $a and $b by the append command..)

thanks

Hi,

I think the error in the code of firepage is the " after $x.

Better:

<input type="checkbox" name="box<? echo $x; ?>">

The . operator ist exactly what you want.

Try this:

<?PHP
$a="box";
for ($b=1;$b<20;$b++) {
$c=$a.$b;
echo "Value of \$c: ".$c."<br>\n";
}
?>

It should work.

Greetings,

oooops - sorry I put in a Quote instead of the semi-colon. - Thomas has the "concatenation" right -(I cheated 'cos I got the spelling from the manual - I still cant quite pronounce it!)

how about use dynamic name for each check box as the loop goes, and use a hidden input to keep track of the length of the loop. then when you want to retrieve value from the form go through the loop of the names again and get those non-null values

example in servlet

for(int i = 0; i<limit; i++)
{
<input type = checkbox name = "theName" + i.toString() value = "theValue">
}

<input type = hidden name= "length" value = limit
