How to add multiple sql queries to paginaiton dynamically?
I am trying to add or connect multiple sql queries dynamically.
I am creating a pagination script and I am trying to add some filter buttons or links in this case when a user clicks on the links, it will add the id to the sql query and then display the results.
To better understand what I am saying, I will show you the script I'm working on:
Below you will see that I have three links; Marketing, Automotive, and Sports. These links represent the filter selections, so when one is clicked like 'Marketing' the the sql query will insert marketing for 'category=$ids'. This works fine, except for when I want to add multiple selections like picking 'M开发者_如何学JAVAarketing' and 'Sports' only and not have 'Automotive' display.
Is there an easy way to add multiple ids to the sql connection instead of just one?
I hope that makes sense, if you need any further explanation let me know. Thanks for any help on this.
<?php
$ids=$_GET['id'];
echo $ids;
$pageN = $_GET['page'];
echo $pageN;
?>

I am not sure what $ids contain, but MySQL has an IN() operator which acts like an or statement IE:
...WHERE category IN(1,2,3,4,5)...
So $ids would need to be a comma delimited list, whether it is an actual title or an id. Hopefully this helps you figure out what you need to do.
You can use IN:
SELECT COUNT(*) as num FROM $tableName WHERE category IN ($id1, $id2, $id3)
You also really, really need to look into the mysql_real_escape_string() function so someone doesn't destroy your database.
