PHP MySQL Problem

[liongold]

I have a problem with a part of a function I have built. This part basically gets selects from the database those rows which have field1 as equal to $r['fieldx'] and echo them. When I try mysql_error() nothing gets put but when I do die("Error"), it gives Error so there is a problem with mysql_fetch_array(). Please help me because I've been trying to find the error for ages but still can't.

$get = "SELECT * FROM ".TBL." WHERE test = '1' && (test = '".$fieldx['ShortVersion']."' || test2 = '".$fieldx['ShortVersion']."' || test3 = '".$fieldx['ShortVersion']."' || test4 = '".$fieldx['ShortVersion']."')"; 
                $getprocess = mysql_query($get) or die(mysql_error());
                echo "<br>Awarding ...";
                //Debug ready till here
                while($getup = mysql_fetch_array($getprocess)) {
                    // This does not run
                };

A while loop not executing could be the result of no matching data.

 

Try simplifying the query

$get = "SELECT * FROM ".TBL." WHERE test = '1'
        AND '{$fieldx['ShortVersion']}' IN (test, test2, test3, test4)";

(judging by those column names it looks like that table is a good candidate for normalization)

[liongold]

With this query: 

$getu = "SELECT * FROM ".TBL_USERS." WHERE confirmed = '1' AND '{."$fieldx['ShortVersion']."}' IN (test1, test2, test3, test4)";

it's still not working. No error messages. The query runs fine and reports no error. 

[Barand]

What do you get if you

echo $getu;

[liongold]

Query was empty message. 

[Barand]

$getu = "SELECT * FROM ".TBL_USERS." WHERE confirmed = '1' AND '{."$fieldx['ShortVersion']."}' IN (test1, test2, test3, test4)";
echo $getu;

Post the output, it is not going to give that error message

[liongold]

SELECT * FROM table WHERE confirmed = '1' AND '{TST}' IN (test1, test2, test3, test4)

[liongold]

Since I want to be sure, you got me right. I am trying to make this a select statement to select all rows where $fieldx['ShortVersion'] is either in driver1 or driver2 or driver3 or driver4. The rows chosen also should have confirmed = 1

[Barand]

The value you are searching for contains the curly braces ie "{TST}". Do any of your db table columns contain that value?

[liongold]

No they contain TST only. The { are from the query itself.. 

[Barand]

So now you know why it isn't working.

'{TST}' != 'TST'

[Barand]

The query you are running is not the same as the one I suggested

 

Mine

$get = "SELECT * FROM ".TBL." WHERE test = '1'
        AND '{$fieldx['ShortVersion']}' IN (test, test2, test3, test4)";

Yours

$getu = "SELECT * FROM ".TBL_USERS." WHERE confirmed = '1' 
         AND '{".$fieldx['ShortVersion']."}' IN (test1, test2, test3, test4)";

If you echo my version you get

SELECT * FROM TBL WHERE confirmed = '1' 
        AND 'TST' IN (test1, test2, test3, test4)

If you echo your version you get

SELECT * FROM TBL_USERS WHERE confirmed = '1' 
        AND '{TST}' IN (test1, test2, test3, test4)

This because {..} has special significance when embedding variables in a double-quoted string. See http://www.php.net/manual/en/language.types.string.php

 

EG

$var = 'World';
echo "Hello $var!";     //--> Hello World!
echo "Hello {$var}!";   //--> Hello World!
echo "Hello {".$var."}!"; //--> Hello {World}!     - your version equivalent

It now works. Thanks for helping.
