[SOLVED] Simple help please

[marklarah]

Right, so the buttons display now, but not the form bit (hence the button doesn't work without the form bit)

 

It should display in the source but it isn't. Im not too good with loops, are you sure the while ($n < ($num/2)){

bit is right? Will it work?

[LemonInflux]

Show me the current code. I've lost track

No, it displays the radios, it doesn't display the hidden forms (if you check the source, it doesn't show them)

[LemonInflux]

Is there a reason behind [pre]while ($n < ($num/2))[/pre]?

yeah, the $info variable is an array, and it stores it in the first block will be a the name of a field, the second the value of it. Then the third block will be the name of another.....and so on. So within each row, there may be many different hidden fields, so that hopefully goes through them, but im running this now (still doesn't work)

$l = $num/2;
$n = 0;
while ($l != ($num/2)){
$m = $n+1;
echo '<input type="hidden" name="'.$info[$n].'" value="'.$info[$m].'">';
$n++;
$n++;
$l++;
}

 

 

When im trying print_r($row) within the last while loop, it doesn't work...

 

 

[LemonInflux]

See if you can spot the problem

 

$l = $num/2; // <---!!!!!!!!!
$n = 0;
while ($l != ($num/2)){ // <-- What did you just define $l as 
$m = $n+1;
echo '<input type="hidden" name="'.$info[$n].'" value="'.$info[$m].'">';
$n++;
$n++;
$l++;
}

I was waiting for you to spot that .... 

 

Ok, $l is now 0, but it still doesn't display anything.

[LemonInflux]

$l = 0;
$n = 0;
while ($l != ($num/2)){ // <-- What did you just define $l as 
echo '<input type="hidden" name="'.$info[$n].'" value="'.$info[$n+1].'">';
$n++;
$n++; // Why twice?
$l++;
}

n is incremented twice, so in the first loop, its $info[0] then $info[1]. So next loop it needs to start at $info[2], and to get 0 to 2, it needs to go up by two.

 

Though I think that the problem may lie in the parent while loop.

[marklarah]

Ok, even when just echoing $num, doesn't work.

[marklarah]

...

[marklarah]

Yup. Still wont work...

[marklarah]

I fixed it...
