PHP - How To Add No Of Clicks In Database ?

Can you see any problems with the code below? It doesn't work.

What I am trying to do is quite straightforward.

The links on my site look like this:

go.php?id=1&url=usa
go.php?id=1&url=uk
go.php?id=2&url=usa
go.php?id=2&url=uk

When a visitor clicks on one of these links, I want to grab the values of the id and url parameters, count the click, and redirect the visitor.

Here's the error that I get when I try the code:

<?php
$conn = mysql_connect('localhost','username', 'password') or trigger_error("SQL", E_USER_ERROR);
mysql_select_db('database', $conn) or trigger_error("SQL", E_USER_ERROR);
$id = intval($_GET['id']);
$url = intval($_GET['url']);
mysql_query("UPDATE urls SET click_counter = click_counter+1 WHERE id=$id");
if ($url=="usa") 
$href = "SELECT usa FROM urls WHERE id=$id";
elseif ($url=="uk")
$href = "SELECT uk FROM urls WHERE id=$id";
elseif ($url=="aus")
$href = "SELECT aus FROM urls WHERE id=$id";
elseif ($url=="can")
$href = "SELECT can FROM urls WHERE id=$id";
else
$href = "SELECT int FROM urls WHERE id=$id";
$qry = mysql_query($href);
list($href)=mysql_fetch_row($qry);
header("Location:$href");
mysql_close($conn);
?>

At the moment  I am creating a search function for my website.
The approach I have in mind is a pseudo-PHP database. To give an example:

A HTML form will submit the results to a PHP file.

HTML FORM - Colour: Black
PHP RESULT PAGE - if ($_POST['color'] == 'Black') {readfile("./products/black/*.html");}
HTML FORM - Price: <$50
PHP RESULT PAGE - if ($_POST['Price'] == '<$50') {readfile("./products/less50/*.html");}

The problem here is if there is an item that is black and costs less than $50, then its going to be listed twice. There is probably some code I can write to ommit the listing of duplicate entries, but it is probably going to be messy, so I am wondering if its better to use a centralized MySQL database, rather than a pseudo-PHP database? I've never used MySQL and don't know much about it and this is my first real attempt at using PHP.

hello everyone,
I am about to start coding my pages to display results from a database but before i do i want to know information about the following :

Is it best to upload images to a database?and display them accordingly? or is it best to use images from a directory? What is most commonly used and or more reliable?

Another topic i have trouble finding information on is actually positioning the output from you mysql database, is this practice done with tables?fields and rows? What is this method called? And is there more then one way to go about controlling result layout on your page?

Sorry about the 1001 questions , but i am unable to find a clear answer on the topic ..especially question two .
Thanks in advance.

I have a very tricky php problem here. At least for me.
On a page that is editing a job entry. I have a database generated group of checkboxes some of which have been checked when the job was entered.

So the script has to do two things generate the complete list of checkboxes and check the ones that have already been selected in the job request. The below script is what I've done trying to figure it out.

Description of what I'm trying to do:
I'm generating the the boxes with a call to my database for the list of checkboxes.
Then I'm building an array with all the possible items that could be checked to compare against.
 
Ok here is where I think my first problem is. I need to make a second query to another table "worklog" in the same database. This is where the list of checked items are stored. What is the best way to do this? A second query seems wrong "or at least not efficient"

       Code: [Select]
<div class="text">Job Type&nbsp;(<a class="editlist" href="javascript:editlist('listedit.php?edit=typelist',700,400);">edit list</a>):</div>
<div class="field">

    <?PHP

    $connection=mysql_connect ("localhost", "user", "password") or die ("I cannot connect to the database.");
    $db=mysql_select_db ("database", $connection) or die (mysql_error());
    $query = "SELECT type FROM typelist ORDER BY type ASC";
    $sql_result = mysql_query($query, $connection) or die (mysql_error());
    $i=1;
    echo '<table valign="top"><tr><td>';
    while ($row = mysql_fetch_array($sql_result)) {
    $type = $row["type"];
        if ($i > 1 && $i % 26 == 0)
        echo '</td><td>';
        else if ($i)
        echo '';
        ++$i;
       
        $aTypes = array ("Spec Ad Campaign", "100 x 100 Logo", "100 x 35 (Featured Developer/Broker)", "100 x 40 (Featured Lender)", "120 x 180 (Home Page Auto)", "120 x 45 (Half Tile - Jobs)", "120x60 (Section Sponsor)", "125 x 40 (Profile Page logo)", "135 x 31 (Autos)", "135 x 60 (Autos)", "135 x 60 (Logotile - Jobs)", "150 x 40 (Auto Logo)", "160 x 240 (monster tile)", "160 x 400 (Skyscraper)", "160 x 600 (Tower)", "170x30 (Section Sponsor)", "240 x 180 JPG/GIF Auto Video", "240 x 180 size FLV video ", "300 x 250 (Story Ad)", "300 x 600 (Halfpage)", "468 x 60 (Banner Jpg/Gif)", "728 x 90 (Leaderboard)", "95 x 75 (Sweeps Logo) ", "Agent Profile Page", "Contest", "Creative Change", "Employer Profile", "Holiday Shop", "Home of the Week", "HP Half Banner (234 x 60 Static)", "Mobile Ads (320x53 *300x50*216x36*168x28)", "Newsletter", "Peelback", "Pencil Ad", "Print", "Real Deals", "Resize ad campaign", "Roll-Over Skyscraper", "Site Sponsor logo (170x30)", "Splash Page Production", "Travel Deals Update", "Video Ad", "Web Development", "Web Maintenance", "Web Quote (or Design)");
       
        $dbTypes = explode(',',$row['type']);
       
        foreach ($aTypes as $type){
       
        if(in_array($aType,$dbTypes)){
       
      echo "<input style='font-size:10px;' name='type[]' type='checkbox' value='$type' CHECKED><span style='color:#000;'>$type</span></input><br/>";
       
        }else
       
        {
       
            echo "<input style='font-size:10px;' name='type[]' type='checkbox' value='$type'><span style='color:#000;'>$type</span></input><br/>";

I have a standard form that displays users current data from a mysql database once logged in(code obtained from the internet). Users can then edit their data then submit it to page called editform.php that does the update. All works well except that the page does not display the updated info. Users have to first logout and login again to see the updated info. even refreshing the page does not show the new info. Please tell me where the problem is as i am new to php.   my form page test.php

<?PHP
require_once("./include/membersite_config.php");

if(!$fgmembersite->CheckLogin())
{
    $fgmembersite->RedirectToURL("login.php");
    exit;
}

?>
<form action="editform.php?id_user=<?= $fgmembersite->UserId() ?>" method="POST">
<input type="hidden" name="id_user" value="<?= $fgmembersite->UserId() ?>"><br>
Name:<br> <input type="text" name="name" size="40" value="<?= $fgmembersite->UserFullName() ?>"><br><br>
Email:<br> <input type="text" name="email" size="40" value="<?= $fgmembersite->UserEmail() ?>  "><br><br>
Address:<br> <input type="text" name="address" size="40" value="<?= $fgmembersite->UserAddress() ?>  "><br><br>

<button>Submit</button>

my editform.php

<?php

$con = mysqli_connect("localhost","root","user","pass");

if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }

mysqli_query($con,"UPDATE fgusers3 SET name = '".$_POST['name']."', email= '".$_POST['email']."', address= '".$_POST['address']."' WHERE id_user='".$_POST['id_user']."'");

Hi guys,

I was just wondering if anyone could help me. I've got a My_SQL database containing articles, a summary for the article and a date. I have a basic CMS system set-up, but I want to create a script that when users sign up to a mail list it forwards the summary and dates of the articles database. If that makes sense? But I only want it to forward the most recent 5 rows. I'm pretty new to PHP and I've been mostly following tutorials thus far, but this is quite specific.

Thanks in advance!

This current code provides an easy way of uploading pictures and having the other pictures move automatically without the need of a database. But I must wonder, if doing this on a database would be faster. Would it be? I mean the example adobe shows I'm only using 19 pictures, but if I ever reach say 1000 pictures, would the php file be too big? Should I just make a database now or it doesn't matter?

Also, the code above, which I took from a phpfreak member, has the pagination not working. Anyone care to do a diagnosis?

Thanks!

Hi,

Just need to know if I am on the right lines, basically I am about to create two tables; one to hold customer information and another to hold information the customer gave me. Both tables will be populated with information that they give me at the same time (in other words from a single form).

Just want to know, if I have a field called ID set to a primary key in both the tables, will that be enough to link them both together?

Furthermore, what would the mySQL code look like if I wanted to view all the information referencing to specific ID? so info from the customer table and the other.

Any and all help would be great.

When I do this:

$matches++;

$sql_update_matches = mysql_query("UPDATE Live_Event SET matches='$matches' WHERE id='$show_id' AND promo_id='$promotion_id'");

But when it should update the database from 0 to 1, it update it to U. What is the problem?

Not sure if I can post this here, or if I should go to a mySQL forum but...     
I'm trying to keep track of my user's "score". Each time they do a certain thing they get a preset amount of points, depending on what they did. The way I see it would be having a table that is joined to the user's ID, and have a column for each task. Then when they do a task the number in that column will go up. Then I will multiply that number by amount the task is worth. I can't just adjust there score because they need to be able to see what they did.

So I hope that made sense. And if you know a better way to deal with this please let me know!

I have two tables one with minfo and other is user both have u_id .

i want to access that id in minfo so that it updates with information by that id of user in that data.

somehow  u_id becomes primary of second table and primary of 1st table.

how should i update the value of u_id in second table any help will be appreacited.
