Inserting data into MySQL server - php

Question

I'm doing a e-commerce admin panel and I need a quick script for inserting data into MySQL. Here's what i've done and it does nothing.
<form action="#" id="form_sample_1" class="form-horizontal" method="post">
<div class="control-group">
<label class="control-label">Package Name<span class="required">*</span></label>
<div class="controls">
<input type="text" name="pkg_name" data-required="1" class="span6 " value=""/>
</div>
</div>
<div class="control-group">
<label class="control-label">Package Price <span class="required">*</span><small>(In Dollars)</small></label>
<div class="controls">
<input name="pkg_price" type="number" class="span6 " value=""/>
</div>
</div>
<div class="control-group">
<label class="control-label">Package Contains</label>
<div class="controls">
<input name="pkg_contains" type="text" class="span6 " value=""/>
</div>
</div>
<div class="control-group">
<label class="control-label">Your Password</label>
<div class="controls">
<input name="sifre" type="password" class="span6 " value=""/>
</div>
</div>
<div class="form-actions">
<button type="button"name="btn" class="btn btn-primary">Send request to server.</button>
</div>
</form>
<!-- END FORM-->
</div> <!--widget box light-grey end-->
<!-- Mass PHP starts here! -->
<?php
echo mysql_error();
include("include/baglan.php");
// set posts here.
$_POST['pkg_name'] = $pkg_name;
$_POST['pkg_price'] = $pkg_price;
$_POST['pkg_contains'] = $pkg_contains;
$sifre = mysql_real_escape_string(md5($_POST['sifre']));
if($_POST['btn'] and $_POST["sifre"] = $sifre){
mysql_query("INSERT INTO packages (pkg_name, pkg_price,pkg_contains) VALUES $pkg_name $pkg_price $pkg_contains");
echo "Success.";
}
else {
echo mysql_error();}
It returns nothing! I've re-written all code but nothing! please help me. The databae variables are;
id, auto incerment
pkg_name text
pkg_price int
pkg_contains mediumtext

Answer 1

Assign variable name should be the left side.
// set posts here.
$pkg_name=$_POST['pkg_name'];
$pkg_price=$_POST['pkg_price'];
$pkg_contains=$_POST['pkg_contains'];
Values() is function, put all vars in bracket and split them with ','.
mysql_query("INSERT INTO packages (pkg_name, pkg_price,pkg_contains) VALUES($pkg_name,$pkg_price,$pkg_contains)");
