[Resolved] Infinite loop?

james_cwy

Say from the previous form, name of two input boxes, containing:
nameh1="qwe"
nameh1="asd"
Then submit to the form with the code below:
I am using a loop rather than coding it again

<?php
$j=1;
$num=2;

while ($j<=$num)
{
$name.''.$j = $_POST['nameh'.$j];
echo "$name".$j;
echo "<br>";
$j++;
}

The problem here is that it only prints qwe infinitely. Any ideas, anyone?

Try using a for loop instead.
Thats what I always do when I have trouble with loops, try another kind.

for ($i=1;$i<=$num;$i++) {
    ##### All your loop data here
    echo "<br>";
}

Or something close to this . . .
Hope this helps.

I used the code provided:
for ($i=1;$i<=$num;$i++) {
$name.''.$i = $_POST['nameh'.$i];
echo "$name".$i;
echo "<br>";
}

but still it prints qwe infinitely. It does not seem to get the value for nameh2 that is asd.
Is there something wrong with this line?:
<<$name.''.$i = $_POST['nameh'.$i]; >>

Yes.
Can't make a variable name and assign it a value, like you have.

Try this :

for ($i = 1;$i <= $num;$i++) {
    $var = $_POST['nameh'.$i];
    echo $var . "<br>"; 
}

But I will need nameh1 and nameh2 for the current form?
Any ideas?

DeadFly

This will loop through and get nameh1 and nameh2.
Here is the exact script I used to test it.

$ArrayA acts as $_POST.

$ArrayA=array('nameh1'=>'qwe','nameh2'=>'asd');
$num=2; 

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

    $var=$ArrayA['nameh'.$i];    

    echo $var."<br>"; 
}

Since I cannot do what I need to do, I used array insteadm so they become $name[$i], ie $name[1], $name[2]

${"nameh$i"} = 'foo!';

But you might as well use arrays, because they allow more flexibility. You can name your form fields as "nameh[1]", etc.
