PHP SQL Insert To DB - php

Question

I have tried a number of different ways of inserting data into my DB I have got a little further it used to just say error but now when you submit the form it loads a blank page, the data from the form isn't added to the table however ;/
<form name="datainsert" method="post" action="dataInsert.php">
<label>Server Name: </label>
<input type="text" name="name" placeholder="Enter Server Name" style="margin-left:90px; width:160px; padding:5px; margin-top:10px;"><br />
<label>Server Location:</label>
<input type="text" name="location" placeholder="Enter Server Location" style="margin-left:71px; width:160px; padding:5px; margin-top:10px;"><br />
<label>Server Operating System:</label>
<input type="text" name="os" placeholder="Enter Server OS" style="margin-left:16px; width:160px; padding:5px; margin-top:10px;"><br/>
<input style="margin-top:10px;" name="submit" value="submit" type="submit">
</form>
<?php
include 'dbconnect.php';
$name = $_POST['name'];
$location = $_POST['location'];
$os = $_POST['os'];
)
mysql_query("INSERT INTO fostvm (name, location, os) VALUES ('$name', '$location', '$os')");
$result=mysql_query($sql);
if($result){
echo "Data Added Successfully";
} else {
echo "Error";
}
?>
Can anyone see a syntax error or where I might be going wrong
thanks!

Answer 1

Try this. your code is Ok just comment this line ($result=mysql_query($sql);). use this code. why you try mysql_qury() two times in your code.
<?php
include 'dbconnect.php';
$name = $_POST['name'];
$location = $_POST['location'];
$os = $_POST['os'];
)
$result = mysql_query("INSERT INTO fostvm (name, location, os) VALUES ('$name', '$location', '$os')");
//$result=mysql_query($sql);
if($result){
echo "Data Added Successfully";
} else {
echo "Error";
}
?>

Answer 2

You have no $sql variable and you are using it mysql_query try this,
<?php
include 'dbconnect.php';
if(isset($_POST['submit'])){ // check for form submit
$name = $_POST['name'];
$location = $_POST['location'];
$os = $_POST['os'];
$result=mysql_query("INSERT INTO fostvm (name, location, os) VALUES ('$name', '$location', '$os')");
if($result){
echo "Data Added Successfully";
} else {
echo "Error";
}
}
?>
Also you should use mysqli as mysql is deprecated
