php mysql search for multiple tables

[tekhead2004]

Hey all,

 

Ive been trying to put together a php page for the last couple weeks that does a query on multiple tables at 1 time, and returns the results from each. In other words, i put in a search, it searches all the tables, then returns the results from whatever tables it finds my data in. each table is extremely different from the other, and as is the data. Im not sure how to manipulate this code to be able to search multiple tables (within the same database) and return the results.  When I say return the results, i basically just want it to spit back and tell me what table/tables it found my query in.  Any help would be greatly appreciated.

 

 

<?php

 

  // Get the search variable from URL

  $var = @$_GET['q'] ;

  $trimmed = trim($var); //trim whitespace from the stored variable

 

// rows to return

$limit=10;

 

// check for an empty string and display a message.

if ($trimmed == "")

  {

  echo "<p>Please enter a search...</p>";

  exit;

  }

 

// check for a search parameter

if (!isset($var))

  {

  echo "<p>We dont seem to have a search parameter!</p>";

  exit;

  }

 

//connect to your database ** EDIT REQUIRED HERE **

mysql_connect("capmastdevaege","admin","jesse&rich"); //(host, username, password)

 

//specify database ** EDIT REQUIRED HERE **

mysql_select_db("assettracking") or die("Unable to select database"); //select which database we're using

 

// Build SQL Query

$query = "select 'asset' results from asset where PARENT_T_TAG = \"%$trimmed%\"  or T_TAG = \"%$trimmed%\"

UNION

select 'sso_extract' results from clearvision where Field1 = \"%$trimmed%\"

UNION

select 'hpsd' results from hpsd where Caller  = \"%$trimmed%\" "; // EDIT HERE and specify your table and field names for the SQL query

 

$numresults=mysql_query($query);

$numrows=mysql_num_rows($numresults);

 

// If we have no results, offer a google search as an alternative

 

if ($numrows == 0)

  {

  echo "<h4>Results</h4>";

  echo "<p>Sorry, your search: "" . $trimmed . "" returned zero results</p>";

 

// google

echo "<p><a href=\"http://www.google.com/search?q="

  . $trimmed . "\" target=\"_blank\" title=\"Look up

  " . $trimmed . " on Google\">Click here</a> to try the

  search on google</p>";

  }

 

// next determine if s has been passed to script, if not use 0

  if (empty($s)) {

  $s=0;

  }

 

// get results

  $query .= " limit $s,$limit";

  $result = mysql_query($query) or die("Couldn't execute query");

 

// display what the person searched for

echo "<p>You searched for: "" . $var . ""</p>";

 

// begin to show results set

echo "Results";

$count = 1 + $s ;

 

// now you can display the results returned

  while ($row= mysql_fetch_array($result)) {

  $title = $row["test"];

 

  echo "$count.) $title" ;

  $count++ ;

  }

 

$currPage = (($s/$limit) + 1);

 

//break before paging

  echo "<br />";

 

  // next we need to do the links to other results

  if ($s>=1) { // bypass PREV link if s is 0

  $prevs=($s-$limit);

  print " <a href=\"$PHP_SELF?s=$prevs&q=$var\"><<

  Prev 10</a>&nbsp ";

  }

 

// calculate number of pages needing links

  $pages=intval($numrows/$limit);

 

// $pages now contains int of pages needed unless there is a remainder from division

 

  if ($numrows%$limit) {

  // has remainder so add one page

  $pages++;

  }

 

// check to see if last page

  if (!((($s+$limit)/$limit)==$pages) && $pages!=1) {

 

  // not last page so give NEXT link

  $news=$s+$limit;

 

  echo " <a href=\"$PHP_SELF?s=$news&q=$var\">Next 10 >></a>";

  }

 

$a = $s + ($limit) ;

  if ($a > $numrows) { $a = $numrows ; }

  $b = $s + 1 ;

  echo "<p>Showing results $b to $a of $numrows</p>";
