I have this php file. The lines marked as bold are showing up the error :"mysql_query() expecets parameter 2 to be a resources. Well, the similar syntax on the line on which I have commented 'No error??' is working just fine.
function checkAnswer($answerEntered,$quesId)
{
//This functions checks whether answer to question having ques_id = $quesId is satisfied by $answerEntered or not
$sql2="SELECT keywords FROM quiz1 WHERE ques_id=$quesId";
**$result2=mysql_query($sql2,$conn);**
$keywords=explode(mysql_result($result2,0));
$matches=false;
foreach($keywords as $currentKeyword)
{
if(strcasecmp($currentKeyword,$answerEntered)==0)
{
$matches=true;
}
}
return $matches;
}
$sql="SELECT answers FROM user_info WHERE user_id = $_SESSION[user_id]";
$result=mysql_query($sql,$conn); // No error??
$answerText=mysql_result($result,0);
//Retrieve answers entered by the user
$answerText=str_replace('<','',$answerText);
$answerText=str_replace('>',',',$answerText);
$answerText=substr($answerText,0,(strlen($answerText)-1));
$answers=explode(",",$answerText);
//Get the questions that have been assigned to the user.
$sql1="SELECT questions FROM user_info WHERE user_id = $_SESSION[user_id]";
**$result1=mysql_query($sql1,$conn);**
$quesIdList=mysql_result($result1,0);
$quesIdList=substr($quesIdList,0,(strlen($quesIdList)-1));
$quesIdArray=explode(",",$quesIdList);
$reportCard="";
$i=0;
foreach($quesIdArray as $currentQuesId)
{
$answerEnteredByUser=$answers[$i];
if(checkAnswer($answerEnteredByUser,$currentQuesId))
{
$reportCard=$reportCard+"1";
}
else
{
$reportCard=$reportCard+"0";
}
$i++;
}
echo $reportCard;
?>
Here is the file connect.php. It is working just fine for other PHP documents.
<?php
$conn= mysql_connect("localhost","root","password");
mysql_select_db("quiz",$conn);
?>
