Question

I have a form with over 100 dynamically named fields, that post to a php file, I want to take all the fields that are posted to the php file which is currently:

Array ( [option_page] => plugin_options 
[action] => update 
[_wpnonce] => a51bfc281a 
[_wp_http_referer] =>/wp-admin/options-general.php page=plug.php 
[13939069] => 
[2171] => 
[3600645] =>
[2168] => 
[13937024] => 
[submit] => Save Changes 
[__qca] => P0-1887521465-1334258158937 
[s_vi] => )

From this I want to insert the data into a mysql table in the format:

id      | option_name     | value
--------------------------------------------
autonum | post data key   | post data value

But the issue is I am only intrested in the post data value after: [_wp_http_referer]
but before [submit] so these can be used as reference points.

The part I am stuggling with is:

• how would I get only that part of the post data dynamically?
• How would I get the required array keys and insert it into the
  table dynamically?

Many thanks!

You mat try this

$start = array_search("_wp_http_referer",array_keys($_POST))+1;
$end = array_search("submit",array_keys($_POST))-1;
$newArr=array_slice($_POST, $start, $end);
foreach($newArr as $k=>$v)
{
    // $k is the key name and $v is the value of that key
    //echo $k."=".$v."<br />";  
    $val=mysql_real_escape_string($v);
    $sql="INSERT INTO table_name VALUES (null, ".$k.", ".$val.")";
    mysql_query($sql);
}
