Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean

[Mushfik]

Hello. Please look at the code below and tell me the correct code for it please. here is the message i get.."Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given"

<?php include("function.php"); ?>

Ok, I'll be as tactful as possible here as this is your first post. Please format and indent your code/markup properly and repost. It's an absolute mess and very very hard to follow.

It's unfortunate that you have javascript, HTML and PHP all mixed up. It's much easier if you separate these as much as possible.

Try to place most of the PHP above the !doctype declaration. JS scripts can usually be placed out of the way right at the bottom of the document, above the closing </body> tag.

BTW mysql_* functions have been deprecated. Do not use them. Use mysqli or PDO instead. Some of us won't touch these functions with a barge pole nor provide helpful answers for them.

[Mushfik]

I don't know how to do any of these would you not be able to find the main line which is causing problem and solve it for me. I would really appreciate it sir

Sorry Mushfik, but as I stated, your code and markup is a complete mess. UNtil you tidy it up, I'm not going to look at it. I assume that will be true for other contributors too.

[Mushfik]

I tried as much as possible to remove otHer things. Please look at it

<?php
              $rewards = mysql_query("SELECT * FROM rewards ORDER BY points");
              $rowNum = 0;
              $rowMax = 4;
              while($row = mysql_fetch_array($rewards))
  {
      if($rowNum ==0){
          echo "....";
      }
      echo "..." align=\"center\" width=\"200px\"><h3 style=\"background:url(../images/historytop.png);\">". $row['title']. $row['img'].
      if(!isset($_SESSION["user"])){
      echo"....."
      } else {
          $userId = $_SESSION["user"];
          $myPoints = mysql_result(mysql_query("SELECT points FROM balances WHERE userId = '$userId'"), 0);
          if($myPoints <=  $row['points']){
              echo"..."
          } else {
                          echo"..."
          }
      }
      $rowNum++;
      if($rowNum >= $rowMax){
        $rowNum = 0;
        echo "</tr>";  
      }
  }
              ?>

Ok, looks better. You may get more bites now.

[Mushfik]

Please i cannot try any better. Please look at the code and see if you can find the problem for me.

<?php
              $rewards = mysql_query("SELECT * FROM rewards ORDER BY points");
              $rowNum = 0;
              $rowMax = 4;
              while($row = mysql_fetch_array($rewards))
  {
      if($rowNum ==0){
          echo "....";
      }
      echo "..."
      if(!isset($_SESSION["user"])){
      echo"....."
      } else {
          $userId = $_SESSION["user"];
          $myPoints = mysql_result(mysql_query("SELECT points FROM balances WHERE userId = '$userId'"), 0);
          if($myPoints <=  $row['points']){
              echo"..."
          } else {
                          echo"..."
          }
      }
      $rowNum++;
      if($rowNum >= $rowMax){
        $rowNum = 0;
        echo "</tr>";  
      }
  }
              ?>

Sorry I've stopped looking at mysql_* functions as it just feeds their use. However, other contributors will now be able to follow your code more easily.

Where is your connection? Check for errors to find the issue.

$rewards = mysql_query("SELECT * FROM rewards ORDER BY points") or die(mysql_error());

[Mushfik]

I have separate php code for connection details and linked in this script with php include. So I have got that. I will try this and will let you know

            $userId = $_SESSION["user"];
             $myPoints = mysql_result(mysql_query("SELECT points FROM balances WHERE userId = '$userId'"), 0);
             $rewardPoints = mysql_result(mysql_query("SELECT points FROM rewards WHERE rewardId = '$rewardId'"), 0);
             if($rewardPoints > $myPoints) {
                echo  "<h2>Redeem Failed!</h2><p>Don't have enough points to make the purchase.  Please go to the Rewards Page and look for a cheaper item.</p>";
             } else {

The boolen is give at line 21. Ignore all the code at the bootom and tell me line to solve the probelm.

Boolen is given at LINE-21

[pritaeas]

I already told you what to try.

[manas1]

echo "......."
on line no 20 you forgot to put ;
it should be
echo ".......";

[Mushfik]

Thanks everyone for all your help. I found the common mistake

I wrote: SELECT * FROM rewards WHERE rewardId = $rewardId
Supposed to be SELECT * FROM rewards WHERE rewardId = '$rewardId'
