Full error:

Warning: mysql_fetch_array() expects parameter 1 to be resource, null given in C:\Users\plagel\Desktop\local\movie_details.php on line 96

 

I know it's something so simple. Here's the code:

As an aside, do you coder-folks get heart pains when you drink 24 diet cokes and stay up for 36 hours trying to find the semi-colon? :(

 

<?php

function calculate_differences($takings, $cost) {
$difference = $takings - $cost;

if ($difference < 0) {
	$difference = substr($difference, 1);
	$font_color = 'red';
	$profit_or_loss = "$" . $difference . "m";
}elseif ($difference > 0) {
	$font_color = 'green';
	$profit_or_loss = "$" . $difference . "m";
}else {
	$font_color = 'blue';
	$profit_or_loss = "Broke even";
}
return "<font color=\"$font_color\">" . $profit_or_loss . "</font>";
}

extract($row_d);

I'm going to guess that either your get_director(); or get_leadactor(); function has a global $movie_result statement in it and is overwriting $movie_result with a FALSE value.

Actually, upon further review (you must have created this code on a MAC because copy/pasting it results in a mess of tab/new-lines) the two functions I mentioned as a possible cause are present in the source code and aren't the cause of the problem.

 

Your query that is setting $review_result is located after the code that is using $review_result, so yes, the value you are passing mysql_fetch_array() does not exist and is a null value.

Well, I'm definitely not on a MAC..it MAY be because I'm using VIM for Windows..

I have the same problem can anyone explain me why this error is coming??

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

 

this is my code..

 

public static function cal_total_price($cid){

 

global $database;

$query=sprintf("SELECT product_id FROM tblcartitem WHERE cart_id=%s",

mysql_real_escape_string($cid)

);

$result=mysql_query($query);

echo("no of rows : ".mysql_num_rows($result));

while($record=mysql_fetch_array($record))

{

echo $record[0];

}

 

}
