php mysql search output

kezkez · December 11, 2008

Hello, I have a search script (search.php) that outputs the query on the same page that the search bar is on. What I want to do is be able to input the parameters into the search bar, click search, and then have the output come up on a new page. Any help is greatly appreciated since I am new to php.

The search page script is currently:

search.php

-------------

<?php

$hostname_logon = "localhost" ;

$database_logon = "mysql" ;

$username_logon = "root" ;

$password_logon = "" ;

//open database connection

$connections = mysql_connect($hostname_logon, $username_logon, $password_logon) or die ( "Unabale to connect to the database" );

//select database

mysql_select_db($database_logon) or die ( "Unable to select database!" );

//specify how many results to display per page

$limit = 10;

// Get the search variable from URL

$var = @$_GET['q'] ;

//trim whitespace from the stored variable

$trimmed = trim($var);

//separate key-phrases into keywords

$trimmed_array = explode(" ",$trimmed);

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

if ($trimmed == "")

{

$resultmsg = "<p>Search Error</p><p>Please enter a search...</p>" ;

}

// check for a search parameter

if (!isset($var))

{

$resultmsg = "<p>Search Error</p><p>Please enter a search parameter! </p>" ;

}

// Build SQL Query for each keyword entered

foreach ($trimmed_array as $trimm)

{

// EDIT HERE and specify your table and field names for the SQL query

$query = "SELECT * FROM contacts WHERE firstName LIKE \"%$trimm%\" OR lastName LIKE \"%$trimm%\" OR address LIKE \"%$trimm%\" ORDER BY firstName DESC" ;

// Execute the query to get number of rows that contain search kewords

$numresults=mysql_query ($query);

$row_num_links_main =mysql_num_rows ($numresults);

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

// 's' is a variable that gets set as we navigate the search result pages.

if (empty($s))

{

$s=0;

}

// now let's get results.

$query .= " LIMIT $s,$limit" ;

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

$row= mysql_fetch_array ($numresults);

//store record id of every item that contains the keyword in the array we need to do this to avoid display of duplicate search result.

do

{

//EDIT HERE and specify your field name that is primary key

$adid_array[] = $row[ 'lastName' ];

}

while( $row= mysql_fetch_array($numresults));

} //end foreach

if($row_num_links_main == 0 && $row_set_num == 0)

{

$resultmsg = "<p>Search results for:" . $trimmed ."</p><p>Sorry, your search returned zero results</p>" ;

}

//delete duplicate record id's from the array. To do this we will use array_unique function

$tmparr = array_unique($adid_array);

$i=0;

foreach ($tmparr as $v)

{

$newarr[$i] = $v;

$i++;

}

// now you can display the results returned. But first we will display the search form on the top of the page

?>

<html>

<body>

<br>

Enter contact parameters to search database:

</p>

</div>

</form>

<?php

// display what the person searched for.

if( isset ($resultmsg))

{

echo $resultmsg;

exit();

}

else

{

echo "Search results for: " . $var;

}

foreach($newarr as $value)

{

// EDIT HERE and specify your table and field names for the SQL query

$query_value = "SELECT * FROM contacts WHERE lastName = '$value'";

$num_value=mysql_query ($query_value);

$row_linkcat= mysql_fetch_array ($num_value);

$row_num_links= mysql_num_rows ($num_value);

//now let's make the keywods bold. To do that we will use preg_replace function.

//EDIT parts of the lines below that have fields names like $row_linkcat[ 'field1' ]

//This script assumes you are searching only 3 fields. If you are searching more fileds make sure that add appropriate line.

$titlehigh = preg_replace ( "'($var)'si" , "<b>\\1</b>" , $row_linkcat[ 'firstName' ] );

$linkhigh = preg_replace ( "'($var)'si" , "<b>\\1</b>" , $row_linkcat[ 'lastName' ] );

$linkdesc = preg_replace ( "'($var)'si" , "<b>\\1</b>" , $row_linkcat[ 'address' ] );

foreach($trimmed_array as $trimm)

{

if($trimm != 'b' )

{

//IF you added more fields to search make sure to add them below as well.

$titlehigh = preg_replace( "'($trimm)'si" , "<b>\\1</b>" , $titlehigh);

$linkhigh = preg_replace( "'($trimm)'si" , "<b>\\1</b>" , $linkhigh);

$linkdesc = preg_replace( "'($trimm)'si" , "<b>\\1</b>" , $linkdesc);

}

//end highlight

?>

<p>

<?php echo $titlehigh; ?>

<?php echo ' '; ?>

<?php echo $linkhigh; ?><br>

<?php echo $linkdesc; ?>

</p>

<?php

} //end foreach $trimmed_array

if($row_num_links_main > $limit)

{

// next we need to do the links to other search result pages

if ($s>=1)

{ // do not display previous link if 's' is '0'

$prevs=($s-$limit);

echo "<div align='left'><a href='$PHP_SELF?s=$prevs&q=$var&catid=$catid'>Previous " .$limit. "</a></div>";

}

// check to see if last page

$slimit =$s+$limit;

if (!($slimit >= $row_num_links_main) && $row_num_links_main!=1)

{

// not last page so display next link

$n=$s+$limit;

echo "<div align='right'><a href='$PHP_SELF?s=$n&q=$var&catid=$catid'>Next " .$limit. "</a></div>";

}

} //end foreach $newarr

?>

What does your code actually do now? What is the problem you are having?

Please surround your code with [ code ] tags.

<?php
if (isset($_POST['search'])){
$query = $_POST['search_query'];
header("location: search.php?q=$query");}

<form method="post" action="search.php?q=">
