Re: [Nolug] php help: storing from variable # of form entries

oops...I spotted some obvious errors now that I am awake!

 <!-- html -->
 <form action="<?echo $PHP_SELF;?>" method="post">
 <?

 for ($i=0;$i < $_POST('SomeNumberToCreate');$i++) {
   ?>
     <input type="text" name="VariableTextInput_<?echo $i;?>" value="">
   <?
 }
 ?>
 <input type="submit">
 </form>
