retrieving values from nested post array

[Lodius2000]

this is a followup to my last topic, which was solved

http://www.phpfreaks.com/forums/index.php/topic,226621.0.html

 

but now the topic has changes enough to warrant a new topic

and a repost of my last post in the previous topic, which contains the question I wanted to ask here

 

so I want to split apart my post array so i can query the db

 

post looks like this

 

$_POST[1]['word']

$_POST[1]['replace']

 

$_POST[2]['word']

$_POST[2]['replace']

 

where the integer is a row number

 

so to split it apart i use

<?php
foreach ($_POST[] as $word, $replace){
      mysql_query("UPDATE badwords SET word = $word WHERE id={$_POST['id']}");
//repeat for replace
}
?>

 

is that right?

 

thanks

<?php
foreach($_POST as $param) {
   $param['word']; // word
   $param['replace']; // replace
}
?>

so generic, where does my id number go, if $_POST[1]['word']

 

i can now retrieve $word but ive lost '1'

 

thanks

Yes, you lose the number, if you want to preserve the number you can do

 

<?php
foreach($_POST as $id => $param) {
   $id; // id number
   $param['word']; // word
   $param['replace']; // replace
}
?>

Reading the foreach entry in the manual could have solved your problem just as easily, if not quicker...
