Yes my SQL statement is a little funny because i have also noticed sme non functional parts of it however i was able to see that the warrior part does work.

This is how the SQL statement looks inside the application:

SQL = "Select id, name, ac, haste, hp, reqlevel from items where reqlevel >= 1 and id = 25462 and classes like %5% and price >= 1 and name = 'itemname' and itemtype = 'something'"

of course i edited it to make it easier to read and post but you can see how it works.

This is alot buggy and will be fixed in the future but it is as functional as i need it to be for testing purposes rigt now.

What happens on the back end is that when you click search it goes through and if a value is present then it adds it to the SQL statement. So above is not always how it looks as it is dynamic and when you type in the id field i believe it disables the rest of the box's. I am not at the actual dev machine now so i can not say definatively.

That's how I ended up doing it on mine, otherwise you run into problems.

On a side note, if you already know the item ID (it is a unique value, no 2 items have the same item id), the other fields don't matter. MySQL ignores the rest because they are redundant. However, you don't usually want to make exceptions in your code if at all possible (HUGE PITA to change later down the line), and since it doesn't usually cause problems to leave it in, you should be fine.

I am a little curious about the Select statement:

Select id, name, ac, haste, hp, reqlevel from items where reqlevel >= 1 and id = 25462 and classes like %5% and price >= 1 and name = 'itemname' and itemtype = 'something'

You mentioned that it's buggy but functional. There are a few things to be aware of (unless you already are) about some of the data types:

First of all, classes requires a bitwise operation because of how it is stored in the items table, because multiple classes can use it, and adding a column for each class can be very hard to read. When I went through discovering the information initially, I put my findings in the Wiki:

classes

* The class or classes can use the item. Remember to add up the results.
o 0 = None
o 1 = Warrior
o 2 = Cleric
o 4 = Paladin
o 8 = Ranger
o 16 = Shadow Knight
o 32 = Druid
o 64 = Monk
o 128 = Bard
o 256 = Rogue
o 512 = Shaman
o 1024 = Necromancer
o 2048 = Wizard
o 4096 = Magician
o 8192 = Enchanter
o 16384 = Beastlord
o 32768 = Berserker
o 65535 = Any/All
* IE, Monk (64) + Shaman (512) = 576

So, instead of using LIKE, you should use & (bitwise AND).

Secondly, name should only be = if you know exactly what the name is, and if you're searching for an item, you typically don't. That is why you normally want to use LIKE. I usually put a little spin on it, because running name LIKE '%Cloth%' can be pretty resource intensive (it searches all of the item names in the database to see if they contain the string "Cloth"). However, if you include an option to search using it as either the beginning or end of the name, it speeds up the results substantially (so name LIKE 'Cloth%', name LIKE '%Cap', or name LIKE 'Cloth Cap'). I usually do the same for the ID field, in case I don't know the exact item #.

In conclusion, this is how I would recommend to change the initial query:

SELECT id, name, ac, haste, hp, reqlevel FROM items WHERE reqlevel >= '1' AND id = '25462' AND classes & '5' AND price >= '1' AND name LIKE '%itemname%' AND itemtype = '0'

Not sure if anyone uses bitwise AND SQL, but I find this info extremely useful. It makes what would take lots of code oftherwise into 1 line.

Say you want to find all items for a mage , you would enter
SELECT classes,id, name FROM items WHERE classes & '4096'

In my job, things like this makes life easier.

Me too, George. I didn't even know about that little jerk until I started messing around with EQBrowser (see page 4 for a working download) and checked out some of the queries. In reality though, I'm not sure how much info is really stored as a bitmask anymore It's just not scalable enough...

I have been very busy with projects at work and sleep i have not done anything at all on this project but wanted to let everyone know it is not DEAD.

A ton of data is stored as bit masks in the peq database. Every class/race combo field. I use the bit mask to save me a ton of time and code. What used to be several thousand lines of code turned into JUST the sql statment and a few box fills.

Trust me, learn the bitmask. You'll be glad you did.

Also, Arrays are your friends. Don't forget that they count them selfs when doing math, store strings with those numbers and CAN be two dimensional (Even more if you need it, two is almost always enough though.)

Not sure this will help any, but I built some arrays in php for these bitwise comparisons. It was so long ago, I am not really sure why I did it this way, but here it is nonetheless.

// Gear slots
$a = 1;
$gear_slots=array(
	"Charm" 				=> $a << 0,
	"Left Ear" 			=> $a << 1,
	"Head" 					=> $a << 2,
	"Face" 					=> $a << 3,
	"Right Ear" 		=> $a << 4,
	"Neck" 					=> $a << 5,
	"Shoulder" 			=> $a << 6,
	"Arms" 					=> $a << 7,
	"Back" 					=> $a << 8,
	"Left Bracer" 	=> $a << 9,
	"Right Bracer" 	=> $a << 10,
	"Range" 				=> $a << 11,
	"Hands" 				=> $a << 12,
	"Primary" 			=> $a << 13,
	"Secondary" 		=> $a << 14,
	"Left Ring" 		=> $a << 15,
	"Right Ring" 		=> $a << 16,
	"Chest" 				=> $a << 17,
	"Legs" 					=> $a << 18,
	"Feet" 					=> $a << 19,
	"Waist" 				=> $a << 20,
	"Ammo" 					=> $a << 21
);

//foreach($gear_slots as $row=>$val) {
//	echo $row.$val."<BR>";
//}

// Char Inventory slots (8)
$s=1;
for($i=22;$i<=29;$i++) {
	$inv="Inventory$s";
	$inv_slots[$inv]=$i;
	$s++;
}

// Char Inventory bag slots (8bags * 10slots)
$b=1; // bag 1
$s=1; // slot 1
for($i=251;$i<=330;$i++) {
	if($s>10) {
		$s=1;
		$b++;
	}
	$bag="Bag$b";
	$bagslot="Slot$s";
//	echo "$bag-$bagslot<br>";
	$inv_slots["$bag-$bagslot"]=$i;
	$s++;
}

// Char Bank Slots (16)
$s=1; // slot 1
for($i=2000;$i<=2015;$i++) {
	$inv="BankSlot$s";
	$inv_slots[$inv]=$i;
	$s++;
}

// Char Bank Bag slots (16bags * 10slots)
$b=1; // bag 1
$s=1; // slot 1
for($i=2031;$i<=2190;$i++) {
	if($s>10) {
		$s=1;
		$b++;
	}
	$bag="BankBag$b";
	$bagslot="Slot$s";
//	echo "$bag-$bagslot<br>";
	$inv_slots["$bag-$bagslot"]=$i;
	$s++;
}


// Create Classes Array
$a = 1;
$classes=array(
	"Unknown" 			=> 0,
	"Warrior" 			=> $a << 0,
	"Cleric" 				=> $a << 1,
	"Paladin" 			=> $a << 2,
	"Ranger" 				=> $a << 3,
	"Shadowknight"	=> $a << 4,
	"Druid" 				=> $a << 5,
	"Monk" 					=> $a << 6,
	"Bard" 					=> $a << 7,
	"Rogue" 				=> $a << 8,
	"Shaman" 				=> $a << 9,
	"Necromancer" 	=> $a << 10,
	"Wizard" 				=> $a << 11,
	"Magician" 			=> $a << 12,
	"Enchanter" 		=> $a << 13,
	"Beastlord" 		=> $a << 14,
	"Berserker" 		=> $a << 15
);

// Create Races Array
$a = 1;
$races=array(
	"Unknown" 	=> 0,
	"Human" 		=> $a << 0,
	"Barbarian" => $a << 1,
	"Erudite" 	=> $a << 2,
	"Wood Elf" 	=> $a << 3,
	"High Elf"	=> $a << 4,
	"Dark Elf" 	=> $a << 5,
	"Half Elf" 	=> $a << 6,
	"Dwarf" 		=> $a << 7,
	"Troll" 		=> $a << 8,
	"Ogre" 			=> $a << 9,
	"Halfling" 	=> $a << 10,
	"Gnome" 		=> $a << 11,
	"Iksar" 		=> $a << 12,
	"Vah Shir" 	=> $a << 13,
	"NPC" 			=> $a << 14,
	"PET" 			=> $a << 15,
	"Froglok" 	=> $a << 16
);

I used these arrays to build the combo boxes on my lookup page. Something like this:

<select name="searchClass" class="advSearch">
	<option value="-1">Pick a Class</option>
	<?php
	foreach($classes as $key=>$val) {
		if(isset($_POST['searchClass']) && $val==$_POST['searchClass']) {
			$selected=" selected";
		} else {
			$selected="";
		}
		echo '<option value="'.$val.'"'.$selected.'>'.$key.'</option>';
	}
	?>
</select>

Again, kinda barbaric, but it works. Good luck with the app. I like the idea.
