Question

I have the following php / sql request:

It is connected successfully and run update successfully (returning success msg), but in phpMyAdmin, the database has not been updated. What am I doing wrong?

<?php 

{ // Connect and Test MySQL and specific DB (return $dbSuccess = T/F)

            $hostname = "localhost";
            $username = "root";
            $password = "";             
            $databaseName = "db_test";    
            $dbConnected = mysql_connect($hostname, $username, $password);
            $dbSelected = mysql_select_db($databaseName,$dbConnected);

            $dbSuccess = true;
            if ($dbConnected) {
                if (!$dbSelected) {
                    echo "DB connection FAILED<br /><br />";
                    $dbSuccess = false;
                }       
            } else {
                echo "MySQL connection FAILED<br /><br />";
                $dbSuccess = false;
            }
}  

//   Execute code ONLY if connections were successful   
if ($dbSuccess) {       

        // SQL to change country value from UK to United Kingdom 
        $company_SQLupdate = "UPDATE tCompany SET ";            
        $company_SQLupdate .= "COUNTRY = 'United Kingdom' ";            
        $company_SQLupdate .= "WHERE COUNTRY = 'UK' ";          
        if (mysql_query($company_SQLupdate))  { 
            echo "UPDATE tCompany.COUNTRY - SUCCESSFUL.<br /><br />";
        } else {
            echo "UPDATE tCompany.COUNTRY - FAILED.<br /><br />";
        }
}

?>

Answer 1

change:

if (mysql_query($company_SQLupdate))  { 
    echo "UPDATE tCompany.COUNTRY - SUCCESSFUL.<br /><br />";
} else {
    echo "UPDATE tCompany.COUNTRY - FAILED.<br /><br />";
}

to

if (mysql_query($company_SQLupdate))  { 
    echo "UPDATE tCompany.COUNTRY - SUCCESSFUL.<br /><br />";
} else {
    var_dump(mysql_error());
}

to see the error

EDIT 1

select * 
from tCompany             
WHERE COUNTRY = 'UK'

to see if there records with COUNTRY = 'UK'
