[PHP-DB] Activating the mysql_clear_password plugin
Hi everyone, I need to use the mysql_clear_password plugin. I'm using the CentOS php 5.3.3 and manually recompiled the mysql mysqli extensions with the Oracle MySQL 5.5 libraries. According to the MySQL documentation ( http://dev.mysql.com/doc/refman/5.5/en/cleartext-authentication-plugin.html), I need to either set the LIBMYSQL_ENABLE_CLEARTEXT_PLUGIN or set the MYSQL_ENABLE_CLEARTEXT_PLUGIN option to the mysql client. I tried to set the LIBMYSQL_ENABLE_CLEARTEXT_PLUGIN via a SetEnv in Apache with no results. Could anyone help me setting the MYSQL_ENABLE_CLEARTEXT_PLUGIN option to the mysql client ?

I tried to set the LIBMYSQL_ENABLE_CLEARTEXT_PLUGIN via a SetEnv in Apache with no results. The SetEnv directive sets variables for Apache's internal environment.the I believe the MySQL docs are refering to the Operating System's environment, which would set this globally for the MyQL server. This is probably not what you want to do as you appear to be trying to do this per connection. You could try using mysqli_options(), but I do not know if that supports this setting yet. The PHP documentation does not mention it, and I am unable to test it myself at the moment. Could anyone help me setting the MYSQL_ENABLE_CLEARTEXT_PLUGIN option to the mysql client ?

Just occured to me, even if the setting is not directly supported yet, you can create a separate configuration file for this setting the client to use the plugin (enable-cleartext-plugin) then: mysqli_options(MYSQLI_READ_DEFAULT_FILE,'myother.cnf'); to use those settings on the connection. -- Niel Archer niel.archer (at) blueyonder.co.uk -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] Prepared Statements - Select - Bind Parameters
Dear list - Thanks to all for your help. I hope [??] that this question will solve all the remaining problems. So that we are on the same page, here is what was previously stated. mysqli_stmt_bind_param expects three variables, in this order mysqli_stmt_bind_param($stmt, num, $a, $b, $c) Where stmt is the query w/ the ?? that is SELECT Site, MedRec, Fname, Lname, Phone, Height, Sex, Hx, Bday, Age FROM Intake3 where 1 AND (Site = ?) AND (MedRec = ?) AND (Sex = ?) and num is the number and type of variables is the query, in this case 'sis' $a $b and $c are the variables to be inserted, in this case: $a = $_POST['Site']; $b = $_POST['MedRec']; $c = $_POST['Sex']; As I seem to have found, the variables cannot be a string or components of an imploded array. This is a search function that will take patient supplied data and search the Intake database to determine the Medical Record Number. There are nine variables in the database, and I never know which variables the patient will give. Based on the database, it is easy to set up the correspondence. The database is searched in the order of the correspondence and the letters can be immediately determined... $a = $_POST['Site'] $b = $_POST['MedRec'] $c = $_POST['Fname'] $d = $_POST['Lname'] $e = $_POST['Phone'] $f = $_POST[Height'] $g = $_POST['Sex'] $h = $_POST['Hx'] $i = $_POST['Bday']'Age' $i = $_POST[] The challenge is to be able to dynamically select the variables that will go intomysqli_stmt_bind_param.

Hi, Many thanks for your quick answer. I tried what you suggest by modifying the phpMyAdmin code and it works great ! Thank you very much !

Advice and help, please Ethan Sounds like you are asking for a solution to a programming problem and not a syntax/language problem. If so, it would be better to see what YOU have already tried and ask for help in fixing or improving that. We're not here to do your programming for you - just to help you with programming problems. We all have situations such as this where we spend the time to Solve the problem. At first glance, I'd have my html present a set of checkboxes tied to the arguments, and then display a new, customized screen to ask for and accept the input only for the checked fields. And btw - is that example of your bind statment REALLY the code as it exists in your current script? I think not.

Re: [PHP-DB] Prepared Statements - Select - Bind Parameters w/ correction
Ethan,
Please accept my apologies for the minor errors in the untested code I
previously provided for your edification.
Consider the following tested code:
?php
/*
CREATE TABLE test (id INT UNSIGNED PRIMARY KEY AUTO_INCREMENT, data
INT UNSIGNED);
INSERT INTO test (data) VALUES (123),(124),(125);
*/
// Faking a POST for testing
$_POST = array(
'id' = 1,
'data' = 123
);
// Don't forget to put your mysql configuration here
$mysql_host = 'localhost';
$mysql_user = 'user';
$mysql_password = 'password';
$mysql_database = 'test';
$dbh = mysqli_connect( $mysql_host, $mysql_user, $mysql_password,
$database );
if( !$dbh )
die( 'Connect failed: ' . mysqli_connect_error() . PHP_EOL );
// Configure the query and the acceptable params to put into the
WHERE clause
$q = 'SELECT * FROM test WHERE 1';
$allowed_fields = array(
'data' = 'i',
'id' = 'i'
);
// Magically put everything together
$types = '';
$args = array();
foreach( $allowed_fields as $k = $type )
{
if( !array_key_exists( $k, $_POST ) )
continue;
$args[] = $_POST[$k]; // Note the addition of the ampersand here
$types .= $type;
$q .= AND ($k = ?);
}
// For debugging and demonstration
echo 'Query: ' . $q . PHP_EOL;
echo 'Bind types: ' . $types . PHP_EOL;
echo 'Arguments:' . PHP_EOL;
print_r($args);
$stmt = mysqli_prepare( $dbh, $q );
if( !$stmt )
throw new Exception( 'Error preparing statement' );
// Put the statement and types variables at the front of the params
to pass to mysqli_stmt_bind_param()
array_unshift( $args, $stmt, $types ); // Note that I've moved this
call. Apparently it doesn't pass back the result. I guess sometimes I
just forget these things.
// mysqli_stmt_bind_param()
if( !call_user_func_array( 'mysqli_stmt_bind_param', $args ) )
throw new Exception( 'Failed calling mysqli_stmt_bind_param' );
if( !mysqli_stmt_execute( $stmt ) )
throw new Exception( 'Error while executing statement' );
mysqli_stmt_bind_result( $stmt, $id, $data );
while( mysqli_stmt_fetch($stmt) )
printf( %d %d\n, $id, $data );
mysqli_stmt_close( $stmt );
mysqli_close( $dbh );
/// end code snippet
I would recommend you consider Jim Giner's remarks as well. PHP's error
message was giving you exactly what you needed to solve the problem with
the code I gave you. There is even a note about using
call_user_func_array() in the documentation about
mysqli_stmt_bind_param(). In fact, the first example in the comments on
the mysql_stmt_bind_param() page shows one way of solving the issue you
are having. (http://php.net/manual/en/mysqli-stmt.bind-param.php)
I think you will find people a lot more willing to help if you can show
that you've done basic research like looking at the documentation for
the function you are trying to use :-)
If you don't understand references, I would recommend reading about
them: http://php.net/manual/en/language.references.php

$g = $_POST['Sex']
$h = $_POST['Hx']
$i = $_POST['Bday']
$i = $_POST['Age'] - Corrected
The challenge is to be able to dynamically select the variables that
will go intomysqli_stmt_bind_param.
