[SOLVED] Better than a Newb

Hi. I'm trying to get a php script working, but it still has errors. Any help is appreciated!

 

What it does:

If a visitor likes a video than he will click on "I Like It" link. This is supposed to trigger a php script that refreshes the page and adds a count to the total number who like the video. Sorta like "Favorited this many times."

 

Here is the code for the page with the link:

 

<?php
$page="1";
?>

<a href="fav.php?page=$page">I like it!</a>

<?php
require("connect.php");

$result = mysql_query("SELECT fav_count FROM favs WHERE page_id = $page");

// echo the number of hits
echo $result;
?>

 

And here is the script that is supposed to be triggered:

 

<?php

// Page ID
$page = $_GET['page'];

require("connect.php");

$result = mysql_query("SELECT fav_count FROM favs WHERE page_id = $page");
$t_count = mysql_num_rows($result);

if($t_count > 0){
$cnt = mysql_result($result, 0, 'fav_count');
$cnt++;
mysql_query("UPDATE favs SET fav_count = $cnt WHERE page_id = $page");
}else{
mysql_query("INSERT INTO favs ( page_id , fav_count ) VALUES ($page, '1')");
}

echo "Thank you for telling us you like this!<br />Please wait...";
echo "<META HTTP-EQUIV=Refresh CONTENT=\"2; URL=favs.php\">";

?>

 

Connecting and the table on the Mysql works fine. It is the above code that has errors. Please help!

Take this:

$result = mysql_query("SELECT fav_count FROM favs WHERE page_id = $page");
$t_count = mysql_num_rows($result);

if($t_count > 0){
$cnt = mysql_result($result, 0, 'fav_count');
$cnt++;
mysql_query("UPDATE favs SET fav_count = $cnt WHERE page_id = $page");
}else{
mysql_query("INSERT INTO favs ( page_id , fav_count ) VALUES ($page, '1')");
}

 

and replace it with

 


$result = mysql_query("SELECT fav_count FROM favs WHERE page_id = $page");
$t_count = mysql_num_rows($result);
if($t_count > 0){
mysql_query("UPDATE favs SET fav_count = fav_count + 1 WHERE page_id = $page");
}else{
mysql_query("INSERT INTO favs ( page_id , fav_count ) VALUES ($page, '1')");
}

 

See how that works out for you...
