Although hard to read, it appears that buyer_query needs a space before the AND.

You cannot mix mysql_xxx with mysqli_xxx functions.

Don't you have to tell mysql_query *which* database connection it is to use for the query? As in mysql_query("select ...", $dbLink)? That's probably why mysql_fetch_array($result) is complaining that $result is not a valid resource....

Print all your query statements and execute it using phpmyadmin(or any mysql browser).

urtrivedi 276 Nearly a Posting Virtuoso · Answer 3 · 2011-09-27T13:21:01+00:00

change your line with line given below

echo $buyer_query="select * from buyer_detail where company_id='{$row['c_id']}' AND buyer_id='{$_GET['buyer_id']}'";

karthik_ppts 81 Posting Pro · Answer 4 · 2011-09-27T14:25:43+00:00

You have missed the single quote before AND

$buyer_query="select * from buyer_detail where company_id='".$row['c_id']. "' AND buyer_id='".$_GET['buyer_id']."'";

Use code tags to post your code

Stefano Mtangoo 455 Senior Poster · Answer 5 · 2011-09-29T16:28:41+00:00

Like other said check your query. You can use code below

db_connect();
$qry="select * from company $where";
die($qry);
$result=mysql_query($qry);
if (!$result) {
    die('Invalid query: ' . mysql_error());
}
$row=mysql_fetch_array($result);

that this is right:

<html> 
	<head></head>
	<body>
		<h1>Student Search Results</h1>
		
		<?php
		
			$searchID=$_POST['searchID'];
			$searchName=$_POST['searchName'];
			$searchMajor=$_POST['searchMajor'];
			$searchGrade=$_POST['searchGrade'];
			$searchGPA=$_POST['searchGPA'];
			
			$searchID=trim($searchID);
			$searchName=trim($searchName);
			$searchMajor=trim($searchMajor);
			$searchGrade=trim($searchGrade);
			$searchGPA=trim($searchGPA);
			
			require_once('../mysql_connect.php'); 
			
			if (!$db_link)
			{
				die('Could not connect: ' . mysql_error());
			}

			$result = mysql_query("
				SELECT *
				FROM student
				WHERE StudentID LIKE '%".$searchID."%'
				AND StudentName LIKE '%".$searchName."%'
				AND Major LIKE '%".$searchMajor."%'
				AND GradeLevel LIKE '%".$searchGrade."%'
				AND GPA LIKE '%".$searchGPA."%'
				");

			while($row = mysql_fetch_array($result))
			{
				echo $row['StudentID'] . " " . $row['StudentName'] . " " . $row['Major'] . " " . $row['GradeLevel'] . " " . $row['GPA'];
				echo "<br />";
			}

			mysql_close($db_link);
		?>
		
	</body>
</html>

but its not working for me :(

Oops. I missed that: selecting the DB to use. :( But at least I got the right neuron to fire!

To expand, you don't *have* to give mysql_query a DB object to use since it will (I believe) use the last one referenced. However, it's good practice to include it; future maintenance and debugging will be easier and there will be less hair loss.
