increment record order

Hello!

having issues with this function, mainly the logic behind it I guess.

I've got a very simple CMS, and order the pages to be displayed on the front end with a TinyInt field in the db.


Function SetPageOrder($numSectionID,$numPageOrder){

// Check Page Order and Increment if needed
$result = mysql_query("SELECT Id,PageOrder FROM pages WHERE ParentID = " . $numSectionID );
while ($row = mysql_fetch_array($result)){
If($numPageOrder == $row['PageOrder'] || $numPageOrder < $row['PageOrder']){
mysql_query( "UPDATE PageOrder SET PageOrder = PageOrder + 1 WHERE Id=" . $row['Id'] );
}
}
}


what i'm trying to do here, is if i create a new page and set the page order to 1 for example, I would like all the other pages in that section to bump up a number. I thought this function would work, but no go.

any ideas would be great,

thanks in advance for your time!

you will need to select all the records that are equal to 1 and more than 1

for example

SELECT * FROM PAGES WHERE PAGE_ORDER =< 1

then loop through all records and update them accordingly
for example

UPDATE PAGES
SET PAGE_ORDER = $row['PAGE_ORDER'] + 1
