I have a HTML form that has a dynamic number of fields (for entry of collected data it adds a new
field each time) and would like to use the variable variable on _POST. This way, I could increment
the field name value with a loop limit when say 100 fields are reached (the max for the form.)
Below is the solution I came up with to work around it:
<?php
$MaxRows=100;
$NumbersOfTime=0;
extract ($_POST,EXTR_PREFIX_ALL,'pos');
for ($i = 1; $i <= $MaxRows; $i = $i + 1)
{
$tmp = "pos_TimeRecorded{$i}";
if (isset($$tmp))
{
$TimeRecorded[$i]=$$tmp;
}
else
{
$NumbersOfTime=$i-1;
break;
}
}
?>
