Error : Please help me :)

[burnside]

Hey all. I have a script that has been working fine, now all of a sudden i get this error :

 

 Warning: mysql_fetch_assoc(): 5 is not a valid MySQL result resource in c:\phpdev\www\public\mem.php on line 275

 

Thhis is the block of code the error line is referring to :

 

$sql = "SELECT * FROM `news` ORDER BY id DESC LIMIT 0,7";
				$result = mysql_query($sql);
				if (!$result) {
    				echo "Could not successfully run query ($sql) from DB: " . mysql_error();
    					exit;
				}

				if (mysql_num_rows($result) == 0) {
    				echo "<p>No news posted. </div></p>";
    					include_once("layout_all/bottom.php");
				exit;
				}

			while ($row = mysql_fetch_assoc($result)) { 
    				
			$row[message] = str_replace($word, $image, $row[message]);
			$row[message] = str_replace($color, $text, $row[message]);
			$row[message] = str_replace($effect, $status, $row[message]);


			echo "<p> {$row["date"]} : {$row["time"]} : Poster {$row["poster"]} <br /> {$row["message"]} </p> <br /> "; 
				if($info[security] >= 8 ) { echo "<p><form action=\"?action=delete\" method=\"POST\"><input type=\"hidden\" name=\"delete_id\" id=\"delete_id\" value=\"{$row['id']}\"><input type=\"submit\" value=\"Delete Post\"> </form> <form action=\"?action=edit\" method=\"POST\"><input type=\"hidden\" name=\"edit_id\" id=\"edit_id\" value=\"{$row['id']}\"><input type=\"submit\" value=\"Edit Post\"></form></p> <br />"; } 




			mysql_free_result($result);


			echo " 	</div>  ";
			}

Any ideas people thanx

The problem is that $result contain null...

because the sql statement was incorrect or the connection was incorrect

[burnside]

it kinda works. it returns 1 result

[freenity]

Then error_reporting(~E_ALL); and you won't see warnings 

[burnside]

that wont solve the problem as it dont run all the script.

[fenway]

see what mysql_error() has to say after the query() call.

[burnside]

where would you put the error? Just i have tried several diffrent places and recived no error.

[burnside]

i use the same query in a diffrent page and it works fine shows the limit number of records why i dont understand why the error

[freenity]

what connection are you using??

maybe there is some kind of error while connecting to the db

see what mysql_error() has to say after the query() call.

You'd better do this EVERY TIME you make a call to a mysql function 

[burnside]

i do if you read the script ,

[burnside]

what connection are you using??

maybe there is some kind of error while connecting to the db

 

connection is fine. i have no idea why the error cos its working fine in the other scripts.

[fenway]

Which one is line 275?

[burnside]

Which one is line 275?

 

Line 275 :

	while ($row = mysql_fetch_assoc($result)) {  

You require any more lines?

 

 

[luca200]

i do if you read the script ,

 

I'm afraid you're right... 

But could be you free the result inside the reading cycle? I can't clearly see where are all of your brackets...

[burnside]

I have tried several diff variations of the code same error, but when i load the script up on a diffrent page {exactly the same apart from the limit is higher} it works

[luca200]

could be you free the result inside the reading cycle

What about this...?

[burnside]

i took if off and it works so how that happen?

[luca200]

It happens that you can't have it inside your cycle

Actually you don't need it at all... anyway I don't believe it can work on another site with that code, unless you had LIMIT 1 in the query

[burnside]

that makes sence because i incresed the limit from 1 to 7 hm.. thanx

[luca200]

In case you did not understand, that instruction "kills" your result. Actually, as it was inside the cycle, you got the error when you tried to read the second line. That's why 'limit 1' works.

It makes sense to have it when you're finished with your result. Anyway you don't need it (php does it for you at the end of the script), unless you need much more time and/or memory after processing your result.
