Re: [phpResource] multilevelscategories

Try to use something like similar. May be it is buggy, but u can find an idea



include "YOUR DB CONNECTIVITY CLASS";
$objDB = new CREATEYOURDBObject();
$arrCategory = array();
getcategory($objDB, 0, 0, $arrCategory);
print_r($arrCategory);
function getcategory($objDB, $nParent, $nLevel, $arrCategory)
{
//$arrCategory = array();
$strQuery = "select * from hosp_categories where parent_id=".$nParent;
$nResult = $objDB->RUNQUERY($strQuery);
while ($rstRow=mysql_fetch_array($nResult)) {
$nID = $rstRow['category_id'];
$strSpace = "";
for ($i=0;$i<$nLevel;$i++)
{
$strSpace .= "&nbsp;";
}
$arrCategory[] = array("ID"=>$nID, "Title"=>$strSpace.$rstRow['title']);
$nCount = $objDB->RecordCount("hosp_categories", "parent_id=".$nID);
if($nCount>0)
{
getcategory($objDB, $nID, $nLevel+1, $arrCategory);
}
}
}

In this case, you will have to check if the current ID has been used as parent or no. If yes, run the query to find its child. Most probably, you will be writing a recursive function to achieve this.

But that means for each level I have to do a select query, and I don’t know how many levels are there, it should be unlimited so how do I do that ??

Hi,

Top most element don't have parent so it's partent_id is 0. Your first query is

Select * from hosp_categories where parent_id = '0'

This will give you the top elements which you can loop and shows in <select. Once the user select any of the element in Top <select you have to pass it's id in query string and run the following query to load the child,

select * from hosp_categories where parent_id = '$ID FROM QUERY STRING'

This will give you the list of child of selected which you can easily show in <select. Same procedure is follow for next level of category. You can go till n level with this approach.

Thanks

Subject: [phpResource] multilevel categories

 

I have categories table with multilevel categories I need to make the insert statement for the sub categories and sub subcategories so I need to populate a <select> box with this tree so I can insert the parent id with the new subcategory

Anyone knows how to populate this select box with the tree ??

 

The table is here

 

CREATE TABLE IF NOT EXISTS `hosp_categories` (

  `category_id` int(10) NOT NULL auto_increment,

  `parent_id` int(10) NOT NULL,

  `title` varchar(255) NOT NULL,

  `description` text NOT NULL,

  `image` varchar(255) NOT NULL default '',

  PRIMARY KEY  (`category_id` )

) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT= 7 ;

If you want all in one select box than you need to make a recursive function which call itself and fetch sub category untill reached last level. Thanks Best...
