Hello,
I need help with a part of my script that should, when finnished, to be able to identify incomming orders by first checking the title and then, where price is = the price, check the identify to find a match.

Here is the database structure;

CREATE TABLE `items` (
`item_id` int(11) NOT NULL auto_increment,
`item_name` varchar(100) NOT NULL default ''
`price` varchar(30) NOT NULL default '',
`identify_pos` varchar(50) NOT NULL default '',
`identify_pos2` varchar(50) NOT NULL default '',
`identify_neg` varchar(50) NOT NULL default '',
`identify_neg2` varchar(50) NOT NULL default '',
`file_name` varchar(100) NOT NULL default '',
`file_pack` varchar(30) NOT NULL default '',
PRIMARY KEY (`item_id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

First the script needs to select all rows where "price" = $item_amount. Then it should check the $item_title and search all rows where the price is $amount and find a match where the $item_title contains "identify_pos" and "identify_pos2" but not "identify_neg" or "identify_neg2".

To clarify, It is the title that should contain "identify_pos" and "identify_pos2" but not "identify_neg" or "identify_neg2" and the identify_ isn't the complete title, just keywords that the title should or shouldn't contain. The incomming transaction contains item_title and item_price
- item_price -> select all items with that price in the database, if only one then that's the correct one : )
- item_title -> if several rows has the same price, then find a matching row by match the item_title with the keywords in the tows ("identify_pos" and "identify_pos2" but not "identify_neg" or "identify_neg2").

If the script finds one match, then continue. If the scripts finds several rows where the price = $item_amount and the title matches the identify_values then it should report it/do something else. Also, if it isn't a problem it would be good if the identify_ also can be empty so if just one identify_pos contains text then ignore the other identify_.

Really thanks in advance to anyone who can help me with this,
/Oskar R

Hello again,
Can this be done with only PHP and "ordinary" MySQL queries or more advanced MySQL queries? Any ideas?

Certainly be a big help if you could post a sample row of the data.

you should be posting this in the mysql thread. this isn't a php question. Please post in the appropriate forums.

Hello,
OK, Now I've, with help, got three suggestions about how it can be done.. The problem is that none of them work as they should..


$data_matches = array();
$sql = "SELECT * FROM `items` WHERE `price`=$item_price";
$query = mysql_query($sql);
while ($result=mysql_fetch_assoc($query)) {
if (strstr($item_title,$result['identify_pos'])!==false &&
strstr($item_title,$result['identify_pos2'])!==false &&
strstr($item_title,$result['identify_neg'])===false &&
strstr($item_title,$result['identify_neg2'])===false) {
$data_matches[] = $result;
}
}

When I try to fetch the result of that code with mysql_fetch_array($result['item_id']) I get an error message.. (Don't know how to get the correct result)


$sql2="SELECT item_id FROM items WHERE price = $item_amount AND (identify_pos and identify_pos2 LIKE '%$item_title%' AND identify_neg and identify_neg2 NOT LIKE '%$item_title%')";
$result2 = mysql_query($sql2);
while ($row = mysql_fetch_array($result2))
{
$found_item = $row['item_id'];
echo $found_item;
}

When I use this code I get this error message; "Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in".. (Don't know how to get the correct result)


$buildquery = "select * from items where price = $item_amount";
if ($identify_pos != "")
{
$buildquery.= " and instr($item_title, $identify_pos) > 0";
}
if ($identify_pos2 != "")
{
$buildquery.= " and instr($item_title, $identify_pos2) > 0";
}
if ($identify_neg != "")
{
$buildquery.= " and instr($item_title, $identify_neg) < 1";
}
if ($identify_neg2 != "")
{
$buildquery.= " and instr($item_title, $identify_neg2) < 1";
}
$result = mysql_query($buildquery);

And when I use this code I either get an error message or the same item. (Don't know how to get the correct result)

These codes might work, my problem is that I don't know how to get the "finnish" right (in other words; I don't know how to the the item_id of the correct result). Any help on this would be very appreciated.

Thanks,
/Oskar R

Hello,
OK, now I've really tried to fix this but I couldn't come longer than this;


$item_amount="2.95";
$item_title="Templates, test, ebooks";

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");

$trimmed = trim($item_title, " \t.");
$keywords = explode(",", $trimmed);
echo $keywords;
echo $keywords[0];
echo $keywords[1];
echo $keywords[2];
echo $keywords[3];

And that echos this;

ArrayTemplates test ebooks

So I guess that's good? Because it was from the beginning "Templates, test, ebooks" but now "Templates" "test" "ebooks" and from what I understand I needed to do that for the LIKE function to function as it should.

The thing I can figure out is how to get a working MySQL querey of that, I've tried but it doesn't work... Here is one, among many others, that I've tried with;

"SELECT * FROM `items` WHERE ((`identify_pos` LIKE '%".$keywords[0]."%' OR '%".$keywords[1]."%' OR '%".$keywords[2]."%'OR '%".$keywords[3]."%' OR '%".$keywords[4]."%' OR '%".$keywords[5]."%') AND (`identify_pos2` LIKE '%".$keywords[0]."%' OR '%".$keywords[1]."%' OR '%".$keywords[2]."%'OR '%".$keywords[3]."%' OR '%".$keywords[4]."%' OR '%".$keywords[5]."%')) AND ((`identify_neg` NOT LIKE '%".$keywords[0]."%' OR '%".$keywords[1]."%' OR '%".$keywords[2]."%'OR '%".$keywords[3]."%' OR '%".$keywords[4]."%' OR '%".$keywords[5]."%') AND (`identify_neg2` NOT LIKE '%".$keywords[0]."%' OR '%".$keywords[1]."%' OR '%".$keywords[2]."%'OR '%".$keywords[3]."%' OR '%".$keywords[4]."%' OR '%".$keywords[5]."%'))"

So could you please help me with the querey? Or at least tell me what to do? I would ge really greatful if you could.. Thanks in advance,
Best Regards
Oskar R
