Question

I´ve been trying to make “most popular article” script

retrieve the most popular is no problem…. but I have tried every “add count+” methods
but the count field in my mysql always shows 0

This is my script

$add = "1";

$counter=mysql_query("SELECT * FROM news WHERE newsid = '".$newsid."'");

while ($ntcounter=mysql_fetch_array($counter)) {    
    mysql_query("UPDATE news SET count = '".$ntcounter[count]+$add."' WHERE newsid = '".$newsid."'")
}

I´m starting to think if the database is not updateable

Is there something I´m missing here?

Answer 1

You can do this in one go:

UPDATE news SET `count` = `count`+1 WHERE newsid = '".$newsid."'

---

EDIT:

<?php 
//TURN ON ERROR REPORTING!!!
error_reporting(E_ALL);

//Type cast the variable to an integer, despite where its set 
(int)$newsid=1;
//or
(int)$newsid=$_GET['id'];
//$newsid="1"; is setting 1 as a string

mysql_query("UPDATE news SET `count` = `count`+1 WHERE newsid=".$newsid);
?>

Note if your not checking or casting type. always remember to use mysql_real_escape_string()
