How do i translate this to prepared statement - prepared-statement

How do I convert this to a prepared statement using mysqli & php?
$db->executeQuery('Update product Set prod_ops_txt = replace(prod_ops_txt, "/' . $img . '.jpg","") Where prod_ops_txt Like ("%/' . $img . '.jpg%")');
i'm looking to do something like this:
$stmt = $mysqli->prepare('Update product Set prod_ops_txt = replace(prod_ops_txt, ?,"") Where prod_ops_txt Like ("%?%")');
$thisImg = '/' . $img . '.jpg';
$stmt->bind_param('ss', $thisImg, $thisImg);
$stmt->execute();
$stmt->close();

It took a bit of fiddling but I finally found the proper syntax myself:
$stmt = $mysqli->prepare('Update product set product_options_text = replace(prod_opts_txt, ? ,"") Where prod_opts_txt Like (?)');
$thisImg = '/' . $img . '.jpg';
$thisImgMatch = '%/'. $img . '.jpg%';
$stmt->bind_param('ss', $thisImg, $thisImgMatch);
$stmt->execute();
$stmt->close();

Wordpress admin - Where in database is it set?

I'm looking to grab admin user emails to use within a contact form. I have 2 admins that I've assigned. I'd like to grab them from the database. Where is/what is the designation point that I can use when I make the sql statment?
You can do the following
global $wpdb;
//comma separated list
$admins=$wpdb->get_var('select group_concat(`user_email`) as `admin_emails` from `' . $wpdb->prefix . 'users` as `users` inner join `' . $wpdb->prefix . 'usermeta` as `usermeta` on `usermeta`.`user_id`=`users`.`ID` where `meta_key`=\'wp_user_level\' and `meta_value` in (8,9,10);');
//array of associated arrays
$admins=$wpdb->get_results('select `user_email` from `' . $wpdb->prefix . 'users` as `users` inner join `' . $wpdb->prefix . 'usermeta` as `usermeta` on `usermeta`.`user_id`=`users`.`ID` where `meta_key`=\'wp_user_level\' and `meta_value` in (8,9,10);', ARRAY_A);
<?php $user_info = get_userdata(1);
echo 'Username: ' . $user_info->user_login . "\n";
echo 'User roles: ' . implode(', ', $user_info->roles) . "\n";
echo 'User ID: ' . $user_info->ID . "\n";
?>
You can pass the User id herer.....
The first thing to do is to create the function. To do so, paste the following code in your functions.php file:
function getUsersByRole($role) {
$wp_user_search = new WP_User_Search($usersearch, $userspage, $role);
return $wp_user_search->get_results();
}
Once done, you can call the function this way:
$editors = getUsersByRole('Administrator');
foreach($editors as $editor){
//$editor now holds the user ID of an editor
}

PHPExcel drawing new lines when combining sheets

I'm combining about 20 excel sheets (user uploaded) using PHPExcel into a report. This is done by using this bit of code:
$filename = APP . 'docs' . DS . 'reports' . DS . $Workbooks[0]['Report']['company'] . '.' . $Workbooks[0]['Report']['report_name'] . '.' . $Workbooks[0]['Report']['extension'];
$blacklist = array('Company Organogram');
$MasterFile = $this->PhpExcel->createMasterFile($filename,$company . '.' . $title,$colour);
foreach($Workbooks as $Workbook) :
if(!in_array($Workbook['Report']['report_name'],$blacklist)) {
$file = APP . 'docs' . DS . 'reports' . DS . $Workbook['Report']['company'] . '.' . $Workbook['Report']['report_name'] . '.' . $Workbook['Report']['extension'];
$MasterFile = $this->PhpExcel->addExternalWorksheet($MasterFile,$file,$company . '.' . $title,$colour);
#unlink($file);
}
endforeach;
$this->PhpExcel->saveToDisk(APP . 'docs' . DS . 'reports' . DS . 'Weekly Reports for Week ' . (date('W') + 1) . '.xlsx',$MasterFile);
I'm working with CakePHP, so there is a helper. saveToDisk simply saves the file to the disc after which it is attached and sent to a mailing list.
All the above works fine. But I'm having issues where the combining process draws in extra lines. For instance, this:
becomes this:
How would I fix this? Is there something I should set so it doesn't draw in all the lines?

Database query to get decimal value in Joomla 2.5

I'm trying to make a query to a database in Joomla 2.5. I have a db named 'example', and I'm trying to get certain value named 'value' (very original) for a user whose id is 949:
$db =& JFactory::getDBO();
$query = $db->getQuery(true);
$user = 949;
$db->setQuery( 'SELECT value FROM example WHERE user_id = ' . $user );
$result = $db->loadObjectList();
echo $result;
However, I'm just getting 'Array' as result (the expected value is a decimal, e.g. 4.5).
Could someone please tell me what am I doing wrong?
$db =& JFactory::getDBO();
$query = $db->getQuery(true);
$user = 949;
$db->setQuery( "SELECT value FROM example WHERE user_id = '" . $user."'" );
$result = $db->loadObjectList();
echo $result;
try this one
$db->loadObjectList() returns an array of objects, which echo can't display. If you want to just return one value from one row, user $db->loadResult() instead.

How to create select list with field_create_field($field) drupal 7 with options

How to create select list, radio buttons, checkboxes with field_create_field() and how to specify the options to be given in these fields
Run this code with the details for an existing field with the properties that you want to copy:
$entity_type = 'node';
$field_name = 'body';
$bundle_name = 'article';
$info_config = field_info_field($field_name);
$info_instance = field_info_instance($entity_type, $field_name, $bundle_name);
unset($info_config['id']);
unset($info_instance['id'], $info_instance['field_id']);
include_once DRUPAL_ROOT . '/includes/utility.inc';
$output = "field_create_field(" . drupal_var_export($info_config) . ");\n";
$output .= "field_create_instance(" . drupal_var_export($info_instance) . ");";
drupal_set_message("<textarea rows=30 style=\"width: 100%;\">". $output .'</textarea>');
That will produce the PHP code used to create the field/field instance. Then you just need to go through the code and make the changes for your new field/instance.

Who user only DB class from PERA?

I want to use only PEAR DB class, I try follow:
$pearPfad ="PEAR_DB-1.7.14/DB-1.7.14/DB.php";
error_reporting(E_ALL);
require_once($pearPfad);
$DB_dbType ="mysql";
$DB_user = "myuser";
$DB_pass = "mypassword";
$DB_host = "localhost";
$DB_dbName ="mydatabase";
$dsn = $DB_dbType . "://" // Build a DSN string (Data Source Name)
. $DB_user . ":" // Required by DB::connect()
. $DB_pass . "#"
. $DB_host . "/"
. $DB_dbName;
$db = DB::connect($dsn, TRUE);
if (DB::isError($db)) {
die("FEHLER: ".$db->getMessage() );
}
$sql = "SELECT id, title , created FROM h1z4e_content";
$res = $db->query($sql);
if (DB::isError($res)) {
die($res->getMessage());
}
while ($row = $res->fetchRow(DB_FETCHMODE_OBJECT)) {
if (DB::isError($row)) {
die($row->getMessage());
}
print ("<p>Hey, it s:<br />" . $row->id . " " . $row->title . " ... and their freaky et: " . $row->created. "</p>\n");
}
$res->free();
// Similar to: mysql_free_resul
$db->disconnect();
But I get this error:
Warning: require_once(PEAR.php): failed to open stream: No such file or directory in /var/www/PEAR/PEAR_DB-1.7.14/DB-1.7.14/DB.php on line 30 Fatal error: require_once(): Failed opening required 'PEAR.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/PEAR/PEAR_DB-1.7.14/DB-1.7.14/DB.php on line 30
I found here in Stack Overflow this link: PHP-PEAR require_once('DB.php');
I don't want install PEAR on my computer.
I want only user PEAR DB class, is this possible without install PEAR?
Yes, but you need to set the include path correctly - in your case, to /full/path/to/PEAR_DB-1.7.14/DB-1.7.14/
