Dynamic array => dropdown issues...

[motionfiend]

Hello all,

While attempting to switch from a hard-coded array to a dynamic array read from a db table, I'm running into a few snags.

I'm using the following function to create the dropdown menu, and it has worked for everything thus far:

//
function showDrop($array, $active, $echo=true){
	$string = '';
	foreach($array as $k => $v){
		$s = ($active == $k)? ' selected="selected"' : '';
		$string .= '<option value="'.$k.'"'.$s.'>'.$v.'</option>'."\n";     
	}
        if($echo)   echo $string;
	else        return $string;
}

...send in the array, prints out a menu. No problem.

But when I try to create the same array dynamically, I can't get it to work.

I'm sure I'm missing something simple, but I've been looking at this too long to see it clearly.

Ideally, I'd like to create the following array:

$my_arr = array('4'=>"Apple",
		      '3'=>"Banana",
		      '2'=>"Orange",
		      '5'=>"Plum");

The table is a simple id/name setup.

The following code I've been trying to get to work to populate and create a similar array:

function setupCategories(){
	include "dbConnect.php";
	$sql = "SELECT * FROM Categories ORDER BY name";
	$result = mysql_query($sql);
	$my_arr = array();
	while($rows = mysql_fetch_array($result)){ 
		$id = $rows['id']; 
		$name = $rows['name']; 
		$my_arr[] .= [$id][$name];
	}
}
setupCategories();

This should be an easy fix, but I'm just not seeing it....any input is much appreciated.

Thanks,
Jeff

You are adding the values to the array incorrectly.

Do it like this:

...
	while($rows = mysql_fetch_array($result)){ 
		$id = $rows['id']; 
		$name = $rows['name']; 
		$my_arr[$id] = $name;
	}
        return $my_arr;
...

On a side note, I was going to mention using a fetch_all function that converts the result into an array, but unfortunately unlike PostGreSQL which has the pg_fetch_all function, MySQL does not have this function in PHP. :(
