multiple table search

Recommended Posts

i have clients' members tables which are created "dynamically".

for example, i have client ABC and their members table would be ABCm, client XYZ will have XYZm and will go the same for all the other clients members' table. by the way, the fields in all of these tables are the same.

i would like to know how is it possible to do a select statement where i can combine all the clients' members tables to do a search? cuz i do not want/have to add table name if there is a new client.

how how?? can anybody assist?

[code]$i=1;
$query=mysql_query("SELECT member_name FROM members");
while ($member=mysql_fetch_array($query)) {
if ($i=1) {
    $tables=($member[member_name].'m');
    $searchfields=($member[member_name]."m.search_field LIKE '$search_item'");
    $i++;
} else {
    $tables=($tables.', '.$member['member_name'].'m');
    $searchfields=($searchfields.'OR '.$member['member_name']."m.search_field LIKE '$search_item');
}
}
$results=mysql_query("SELECT * FROM $tables WHERE $searchfields");
while ($row=mysql_fetch_array($results)) {
echo("$row['fieldname1'], $row['fieldname2'], $row['fieldname3'].....");
}[/code]

I *think* (not tested dont blame me) that may do it it should list all members in your members table and check to see if $search_item (what ever variable your searching for) is in search_field (field name in your table your searching) and then should return all the values which matched the search


Dont know if this is exacly the fastest way in the world but im at work listening to cmr's complaint about SW problems saying they want engineers so this is the way i came up with :)

Does that explain it better?

session_save_path("../servertemp");
session_start();
if(empty($_SESSION[login]))
//check if the user has logged in, if not redirect the user to login page
{
    $_SESSION[error]="Access Denied! You need to login first.";
    header("Location: ../login.php");
}

[/code]


i'm getting the clientCode from the clients' table to match to .m for get all the tables with clientCode.m
from there, i will get all members from all the .m tables, right?? then will print out what i've searched for.

i have one other non-members table where it will output whatever i typed in to the textfield for the search, and then print the results.

my fren has seen the codes and think there's no problem with it. however there is an error when i have it run. i aint sure if it's my localhost that is giving the problem, or the code itself. but just want to check that what i'm doing, is correct right??

assist please.

%$keyperson%
needs to be
'%$keyperson%'


Give that a go.. also what is the error? might help using

$query=mysql_query("SELECT clientCode FROM client") OR die(mysql_error());

instead of just

$query=mysql_query("SELECT clientCode FROM client");


Do the same for any other querys and will tell you where the error is.. as i said i havn't been able to try this myself so not sure if i missed anything anywhere.

i keep getting a parse error at line 44. it said something like " parse error '[' .... at line 44." but at line 44 there isn't any [].

i think the

$mkeyperson = ["name"];

in your link 44 should be

$mkeyperson = $_POST["name"];
