1) How do I add a simple page counter to a PHP page and insert the values in a MySQL table? Also I would need the MySQL table value to be updated with each new visit.
2) The trick is that the PHP page is a template for a variety of user generated landing pages. For example, I would like each of these pages to have their own separate counters:
examplesite.com/template.php?getvalue=bob
examplesite.com/template.php?getvalue=sam
examplesite.com/template.php?getvalue=samantha
My impression is that if I put the counter on the "template.php" file then it will add up all the visits from each user to a grand total. The output that I would like is to have each user only get counts for the individual landing page.
So, if there are a total of 12 visits, dispersed as follows:
examplesite.com/template.php?getvalue=bob had 4 visits
examplesite.com/template.php?getvalue=sam had 2 visits
examplesite.com/template.php?getvalue=samantha had 6 visits
then I would want bob's page counter to read as '4', sam's as '2' and samantha's as '6.' Am I correct in assuming that if I just put the counter on template.php that each user's landing page would read as '12?' Do you have a solution for an easy way to fix this?
That's pretty simple:
pdo::prepare( 'UPDATE counter SET hits = hits+1 WHERE value = ?');
pdo::execute($_GET['getvalue']);
if ( pdo::rowCount() == 0 ) {
pdo::prepare('INSERT INTO counter (?,0)');
pdo::execute($_GET['getvalue']);
}
Well, just as you are able to separate the requests for bob and sam when generating the page, you can do the same for the counter?
You'll probably do something with $_GET['getvalue']. Just use that value (escaped, paramterized etc) in a query to update your counter....
UPDATE yourtable SET count = count + 1 WHERE pagename = ?
and then bind the getvalue...
You would want to have a row in your MySQL table for each user. When you go to update the table, update the appropriate row for that user by reading the getvalue. Then do the same for displaying the user's page counter.

I'm going to be building a page counter for a site to determine views of different pages. Basically, I have users that I'd like to track with respect to page views of about 120 specific pages.
I'm having trouble determining the most efficient way to do this as well as the logic behind it. I was trying 3 tables, but this would end up in many unnecessary rows. I thought storing an array in a single field then updating the array, but I'm not sure this will grow or if it is even possible. Below is my way of limiting the number of requests. Basically every 100 will count 100. Any ideas for structuring this?
$sample_rate = 100;
if(mt_rand(1,$sample_rate) == 1) {
//update set query
}
Based on our conversation in the comments I would recommend the following simple design:
TblPages
--------
Page_Id (pk)
Page_URL (unique)
TblViews
--------
View_Page_Id
View_User_Id
View_Count
(pk is View_Page_Id + View_User_Id)
Whenever a user views a page, you execute a stored procedure that will either insert a record to the TblViews table if there is no record for that user and page, or update the View_Count of the existing record.
To get all the views for a page you use SUM(View_Count) and group by View_Page_Id, to get all the page views by a user you group by View_User_Id, etc.
Is there a way that will allow me to limit the amount of profiles a user can look at on my site per day. so for instance each user has an id 1, 2, 3 etc. and if the one user views 5 profiles all together in one day then it stops them viewing any more and redirects them to a sign up page to become a paid member where they can view unlimited profiles?
I'm quite new to php and sql but this is primarily what i am working in if there's a way to do it in that.
Thanks
At your database create 1 table called user_views with 3 fields
id (auto increament), user_id (the user who is visiting), visited_user_id (the user id who is visited)..
At your user_details page which users see other user, at the start of your code set 1 function which will add that view to this table , if user has already visited this user it must ignore it and if user has make all allowed visits this function will redirect him ...
And the db table must be truncate each day at 00:00:00..
I think a simple use of SESSION variables and a counting mechanism would suffice.
yes you can limit them in viewing,
you can save it in database and every time they view each profile then save it into ur database, you can make a table,
tbl_user_view
field: user_id, view_count
every profile view make an update function wich
UPDATE tble_user_view set view_count = view_count + 1 WHERE user_id = user_id
and here's some twist, if the user viewed the same profile twice you need to record it as 1,
so save the id of the profile that they viewed in COOKIES or if you do not care on database load you can save it there.
Yes. Each time the user views a profile, store that information (viewer, who they viewed, a time stamp).
Every time they go to view a profile, check how many profiles they have viewed today. If it's over the limit, redirect them.
There's other logic you may want to consider, for example, if they come back to the same profile 5 times, does it count each time?
I have searched everywhere but could not get anything. The scenario is that when I run a select statement from MySQL/PHP, I want to use Next & Previous buttons to navigate backwards and forward through the results.
Does anyone know how I can accomplish this?
Here's how I run the query: select everything from members where hair = black;
This returns 8 results, and I have a page like so details.php?id=3 which takes id and display the details.
I want to be able to keep clicking the next button and move to another id from the result.
How do I accomplish this?
Thank you for your assistance.
If you mean to display 1 product details per page with Next buttons, then
1) Get the total rows from table
2) Find total number of pages like
$totalPages = $totalRows; //since 1 record per page
3) Loop thru $totalPages value to generate next links
4) Get the id of product from page url $_GET
5) Query sql using te product id obtained frm GET
Well thats the basics, hope your get it
Assuming you have all ids in the $allIds var, try something like this:
<?php
$id = (int) $_GET['id'];
$key = array_search($id, $allIds);
$nextId = $allIds[$key+1];
?>
Well, you have 2 different scopes here to address, first, when you query you are in PHP/Server side mode. PHP gets some data, processes it, shows some of it to the knowledge i have of your problem and then sends it to the browser.
Next, you have the client scope, where the client has the HTML rendered to his screen and has the possibility to click NEXT and PREVIOUS. When he does that, he issues a request to the server to get the NEXT or PREVIOUS record based on the current one.
You have 2 scenarios to work this problem out:
1) Load the whole data into memory and scan it to find your current position, see if there is a NEXT and PREVIOUS element and respond to the request of the user. If the user asked for the NEXT, easy, just move one more record. If the user asked for PREVIOUS item, then when scanning using a WHILE or FOR/FOREACH, always keep in memory the "lastitem" you saw, you can use this "lastitem" as your PREVIOUS item.
2) In the event you have many (i mean like more than 1000) items, you need to use a little subquery magic and work this out using SQL.
select everything from members where hair = black AND id = XYZ ORDER BY id LIMIT 2;
This will return you the CURRENT AND NEXT elements. Then call the same query again but this time, order it DESC so that your 2 items are the CURRENT AND PREVIOUS.
select everything from members where hair = black AND id = XYZ ORDER BY id DESC LIMIT 2;
Note that you can order this the way you want, the goal is to get a static result, something that always gets out the same way so that you can reverse it and get the items around the selected one.
I hope this helps you
I write some simple article scripts. Now I want add some article counter.
If there have 3 possibility it should make an article counter.
the article has been opened for read.(only one whole article per page, it will count 1 time)
the article has been searched in a content search list(with title and short content description 5 items per page, it will count 1 time. then if open to read whole article content, it will count another 1 time.)
the article has been showed in the home page by Random (with title and short description, it will count 1 time)
Is there any good suggestion how to do these better?
Which database design is better? put article and count number in one table? or make two tables?
Can anyone recommend me some php article counter script, if the main rules write into a file like class.php then include into my every page.
Thanks.
If you are counting the number of hits on an article, create a column and add one to it every time somebody accesses the page.
Something like:
$sql = "UPDATE table SET count=count+1 WHERE id='$id'";
mysql_query($sql);
Would increment the column count in the table table by 1. Then you could just retrieve that value.
What you could do is use the database that auto increments and just increment that value when the page is viewed, and display that value if you want.
Here is how you can setup the auto increment.
Then update the "value" (you don't have to actually update anything it will AI)
mysql_query("UPDATE COUNTER SET HITS = ''");
Then just display the view
$result = mysql_query("SELECT * FROM PAGEVIEWS");
while($row = mysql_fetch_array($result))
{
echo $row['COUNTER'];
}
This is off the top of my head - it should work.
What is the best way to count page views for dynamic pages like the url example below? I'm using PHP and MySQL. A brief explanation would help. Thanks!
http://www.example.com/posts/post.php?id=3
Usually the table structure looks like this:
table pages:
id | name | ...
==========================
1 Some Page
2 Some Other Page
table pages_views:
page_id | views
================
1 1234
2 80
where pages_views has a unique index on page_id
The MySQL statement to increment the views then looks as follows:
INSERT INTO `pages_views` SET views=1 WHERE page_id=?
ON DUPLICATE KEY UPDATE views=views+1 ;
Since pages_views.page_id is unique, the row for the page will get created if it doesn't exist; if it exists (that's the "duplicate key" clause), the counter will be incremented.
I chose two separate tables here, as CMS pages usually aren't updated too often (and therefore, their load is mostly reads), whereas page views are read and updated, well, with each page view.
This is my code and it's working properly when I open the page or When I refresh the page, page views is incrementing by 1. If the page_id doesn't exist it will insert a record with views = 1, if page_id exists it will increment the views
`INSERT INTO pages_views ( pages_id, views) VALUES ( $page_id, 1) ON DUPLICATE KEY UPDATE views=views+1`
With PDO you will have something like this
$sql = "INSERT INTO pages_views ( pages_id, views) VALUES ( :pageId, 1) ON DUPLICATE KEY UPDATE views=views+1";
$q = $conn->prepare($sql);
$q->execute(array(':pageId'=>$pageId));
Well, you can simply add a field pageviews to your pages table and do UPDATE pageviews = pageviews +1 WHERE id = 1 query on each page load
For the sake of viewing statistics by day/week/month/year, I have made two tables. The first archives all visits to the site with my page and id saved on the same row. The second table records tallys, such as Piskvor describes.
The benefit is that I can view stats for any page and ID I want over time (but that'll be a lot of rows over time...) or I can simply view total pageviews. For the visitors of my site, I serve information from this second table, but my admin panel makes full use of the first table.
statsEach
- statID
- page (example: page 100 is index.php, or 210 is news.php)
- id (example: 1 is news story 1, 2 is news story 2,...)
- date
- time
- user
and
statsTotal
- statTotalID
- page
- id
- total
I don't know what you need/want to do, or even if my table structure is best, but this works for me.
Just increase an integer on the post you currently serve.
