It's bypassing the first condition and it goes straightly to the else condition...

 

Anyone?

//  ...

$ic_row is an array of arrays. You are searching for a scaler value; it will never be found.

 

You probably meant to do $ic_row[$c] = mysql_result($ic_result, $c);

What exactly are you trying to achieve? Your code is unnecessarily complex.

 

Thorpe I have this merge table name "item_category" where all items' categories are stored. It's all stored using an html checkbox

 

What I'm trying to do, If I want to edit an item category,  I'm want to retrieve those categories and check all the those that are listed as category in a checkbox.

 

I'm trying to use "in_array" to store all the stored categories on an iteam.

 

so it's like

 

check all categories in_array(category1, category2) from table category using a forloop to display all categories.

 

 

I wonder if this is possible using in_array?

		$ic_row[$c] = mysql_fetch_array($ic_result);

//  ...

			if(in_array(mysql_result($cat_result,$i,'cat_id'),$ic_row,TRUE))

This solves it.

 

Thanks DavidAM!  :D
