Insert _POST data from a form into MYSQL dynamically - php

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!

Answer 1

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);
}

$counter = 0;
foreach($_POST as $key=>$value)
{
if($key == "_wp_http_referer")
{
$counter = 1;
}
if($counter == "1")
{
if($key != "submit")
{
mysql_query("INSERT INTO table_name(id, option_name, value) VALUES ('','".mysql_real_escape_string($key)."','".mysql_real_escape_string($value)."')");
}
}
}

Answer 3

The keys you want seem to be all numeric, so you could only store those. Like others before me, I also suggest using PDO for added security and convenience.
$dbh = new PDO("mysql:host=$host;dbname=$dbname", $user, $pass);
foreach($_POST as $key => $value) {
if(preg_match("/^[0-9]+$/", $key) {
$stmt = $dbh->prepare('INSERT INTO table_name(option_name, value) VALUES (?, ?)');
$stmt->execute(array($key, $value));
}
}

Answer 4

You could do something like this:
$discard_array = array('option_page', 'action', '_wpnonce', '_wp_http_referer', 'submit', '__qca', 's_vi');
$good_array = array();
foreach ($_POST as $key => $val)
{
if (!in_array($key, $discard_array)) $good_array[$key] = $val;
}
// use $good_array to insert your data into db
print_r($good_array);
Or, if all of the "good" values have always numeric keys, here's a simplified variation:
$good_array = array();
foreach ($_POST as $key => $val)
{
if (is_numeric($key)) $good_array[$key] = $val;
}
print_r($good_array);
Hope that helps.
