variable loop

[slighltywhacked]

Lets say I have 4 variables
$var1
$var2
$var3
$var4

and I want to do the exact same thing to all of them (put them in a database) but I need to do it in a loop. In hte loop I need to call $varx where x is 1,2,3,4. the x goes up each itteration. so the first time through $varx would be $var1 , and the second time var2
Its kind of hard to explain the effect Im going for.. I hope you can figure it out from that

Hi,

The best thing to do is to store those variables in an array to start with. Instead of having $var1, $var2, etc., you should have the values stored in $var[1], $var[2], ..etc. Arrays are very useful because you can use loops to display them or change them.

how could i get an array from a form

the variables are comming from those checkboxes things. They are called $var1 $var2 and so on

Hi,

Simple! Name them $var[0], $var[1] and so on.

Easy ...

<input type=checkbox name='var[]' value=val1>One
<input type=checkbox name='var[]' value=val2>Two
<input type=checkbox name='var[]' value=val3>Three

If, for example, the first and the third checkboxes are selected, you'll get an array with $var[0] = 'val1', $var[1]='val3'
