I have tbl_invoice.first_name and tbl_invoice.last_name as name, so want to search by name in Codeigniter with LIKE.
(example: first_name = Sanjib, last_name = Sarkar, name = Sanjib Sarkar . Search by "Sanjib Sarkar")
$this->db->select('tbl_invoice.*,tbl_members.*');
$this->db->from('tbl_invoice');
$this->db->join('tbl_members', 'tbl_members.id = tbl_invoice.member_id', 'left');
$this->db->like(CONCAT('tbl_invoice.first_name'." ".'tbl_invoice.last_name'), $search_value);
$query = $this->db->get();
Use this code to check value from first and last name using single like query
$this->db->select('tbl_invoice.*,tbl_members.*');
$this->db->from('tbl_invoice');
$this->db->join('tbl_members', 'tbl_members.id = tbl_invoice.member_id', 'left');
$this->db->like("(`first_name` LIKE '%m%' OR `last_name` LIKE '%m%')");
$query = $this->db->get();

I am working on a component where I want to show all users of a specific usergroup. Right now I found two solutions for this but I'm not feeling comfortable with both of them.
Solution 1
$usersID = JAccess::getUsersByGroup(3);
$users = array();
foreach($usersID as $cUserID)
{
$users[] = JFactory::getUser($cUserID);
}
This one seems to produce two database queries every time JFactory::getUser($cUserID) is called. I really don't want this.
Solution 2
function inside model
function getUsers()
{
if(!isset($this->users))
{
$groupID = 3;
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$select = array( 'users.id', 'users.name');
$where = $db->quoteName('map.group_id') . ' = ' . $groupID;
$query
->select($select)
->from( $db->quoteName('#__user_usergroup_map', 'map') )
->leftJoin( $db->quoteName('#__users', 'users') . ' ON (map.user_id = users.id)' )
->where($where);
$db->setQuery($query);
$this->users = $db->loadObjectList();
}
return $this->users;
}
This one works like a charm but I feel there should be a "more Joomla! way" of doing this. I don't like working on their tables.
Right now I'm going with solution 2 but i really wonder if there is some better way to do it.
In my Application_Model_DbTable_User, I have the following function:
public function deleteUser($username)
{
$this->delete('username = ' . (string) $username);
}
This function is being called from my AdminController, with this three lines of code.
$uname = $this->getRequest()->getParam('username');
$user = new Application_Model_DbTable_User();
$user->deleteUser($uname);
This error however, turns up.
Column not found: 1054 Unknown column 'test' in 'where clause'
With test being the user I am trying to delete.
This code is adapted from a previous code which deletes based on id, a INT field, which works perfectly fine. What am I doing wrong? I would be happy to give more detailed codes if needed. Thanks.
Your query isn't quoted:
$this->delete('username = ' . (string) $username);
This equates to:
WHERE username = test
If you use the where() method, it will do this for you:
$table->where('username = ?', $username);
Or (like the example in the docs):
$where = $table->getAdapter()->quoteInto('bug_id = ?', 1235);
$table->delete($where);
I want to get the contents from a row in the Postgresql database and compare the lowercase version of it to a lowercase version of a user input to check if it exists in the database.
i tried:
"SELECT LOWER(name) FROM user_names WHERE name LIKE '%$search%' ORDER BY name ASC"
but that make query not working at all.
EDIT
I am trying to implement an autocomplete Jquery UI like here:
http://jqueryui.com/demos/autocomplete/#remote
for search box (for names)
using javascript and php.
php code:
$search = ($_GET['term']);
if (!$con)
{ die('Could not connect: ' . pg_last_error ());}
else
{
$sql = "SELECT name FROM users_table WHERE name LIKE '%$search%' ORDER BY name ASC";
$result = pg_query($sql);
$json = '[';
$first = true;
while ($row = pg_fetch_array($result))
{
if (!$first) { $json .= ','; } else { $first = false; }
$json .= '{"value":"'.$row['name'].'"}';
}
$json .= ']';
echo $json;
exit();
}
JavaScript code:
$(document).ready(function()
{
$('#auto').autocomplete(
{
source: "./file.php",
minLength: 3
})
})
all above work great.. exactly like in Demo here: http://jqueryui.com/demos/autocomplete/#remote
my problem is that the names in database stored in Uppercase (e.g. LORI)
and of course the user prefers to insert a lowercase in search box to search for name (e.g. lori). but since it stored in uppercase, i need to convert it.
i tried as your suggestion :
$sql = "SELECT LOWER(name) FROM users_table WHERE name ILIKE '%$search%' ORDER BY name ASC";
then i got an empty drop down list!
pretty weird!
thanks in advance.
Google is your friend:
SELECT LOWER(name) FROM user_names
WHERE name ILIKE '%$search%' ORDER BY name ASC
How do I do this sql query in Zend Framework, I need to some how do this in the PDO context I think? I tried ->query but not sure if I am getting this right. The three variables are user_id and to and from date.
SELECT
ss.subcategory_id,
ss.subcategory_name,
ss.subcategory_issaving,
IFNULL(SUM(m.mv_monthly_total),0) AS expendsum
FROM
(SELECT
s.subcategory_id,
s.subcategory_name,
s.subcategory_issaving
FROM
subcategory s
WHERE
s.subcategory_isexpend = 'Y'
AND
s.subcategory_issaving = 'Y') ss
LEFT JOIN
mv_monthly m
ON ss.subcategory_id = m.mv_monthly_subcategory_id
AND m.mv_monthly_user_id = 2
AND m.mv_monthly_month >= '2010-01-01'
AND m.mv_monthly_month <= '2020-01-01'
GROUP BY
ss.subcategory_id,
ss.subcategory_name,
ss.subcategory_issaving
ORDER BY
ss.subcategory_issaving DESC,
expendsum;
I have tried the following with no luck
$db = Zend_Db_Table::getDefaultAdapter();
$dbExpr1 = new Zend_Db_Expr("s.subcategory_id, s.subcategory_name, s.subcategory_issaving");
$dbExpr2 = new Zend_Db_Expr("ss.subcategory_id, ss.subcategory_name, ss.subcategory_issaving, IFNULL(SUM(m.mv_monthly_total),0) AS expendsum");
$select = $db->select()
->from(
array(
'ss' => new Zend_Db_Expr(
'('. $db->select()
->from(array("s" => "subcategory"), $dbExpr1)
->where("s.subcategory_isexpend = 'Y'")
->where("s.subcategory_issaving = 'Y'") .')'
)
),
$dbExpr2
)
->joinLeft(array("m" => "mv_monthly"), "ss.subcategory_id = m.mv_monthly_subcategory_id")
->where("m.mv_monthly_user_id = ?", $user_id)
->where("m.mv_monthly_month >= ?", $fromMonth)
->where("m.mv_monthly_month <= ?", $toMonth)
->group(array("ss.subcategory_id","ss.subcategory_name","ss.subcategory_issaving"))
->order(array("ss.subcategory_issaving DESC", "expendsum"));
$row = $db->fetchAll($select);
For such a complex query, you can just execute it directly rather than using the object oriented approach as it gets fairly complicated with a query like that.
Try something like this, replacing my query with yours, and binding your variables into the query:
$db = Zend_Db_Table::getDefaultAdapter();
$stmt = new Zend_Db_Statement_Pdo($db, 'SELECT a, b, c FROM a WHERE username = ? AND date = ?');
try {
$res = $stmt->execute(array($user_id, $fromMonth));
if ($res) {
$rows = $stmt->fetchAll();
}
} catch (Zend_Db_Statement_Exception $dbex) {
// log Query failed with exception $dbex->getMessage();
}
If you prefer to use the object oriented approach, or need to because some parts of the query will be conditional, I usually build by subqueries up first as their own select, and you can simply embed those in to the main query with the select object for the subquery.
Here is what I mean by that:
$subselect = $this->getDbTable()
->select()
->from('mytable', array('time' => 'max(time)', 'id'))
->where('id IN (?)', $serialNumbers)
->group('id');
$select = $this->getDbTable()
->select()
->setIntegrityCheck(false)
->from('mytable')
->join('other', 'mytable.id = other.id', array('label'))
->join(array('dt' => $subselect),
'(mytable.time, mytable.id) = (dt.time, dt.id)', '');
I am trying to create a simple fb app that retrieves the name of the user using fql_query.
Code :
require_once 'facebook.php';
$appapikey = 'xxxx';
$appsecret = 'xxxx';
$facebook = new Facebook($appapikey, $appsecret) ;
$user_id = $facebook->require_login();
$q = "SELECT name FROM user WHERE uid='$user_id'";
$name = $facebook->api_client->fql_query($q);
echo "Name : $name[0][name]";
Output:
Name : Array[name]
Can you tell me what's going wrong here?
Thanks!
Mistake is in this line:
echo "Name : $name[0][name]";
you are including $name[0][name] in quotes, this should be
echo "Name : {$name[0][name]}";
or
echo "Name : ".$name[0][name];
An FQL query always returns an array, even if there is only one item in the result. Think of the result as rows in a normal SQL query.
Any time that I use arrays or database/API calls in PHP I print_r($array_name) to see what was returned. So this:
$name = $facebook->api_client->fql_query("SELECT name FROM user WHERE uid=$user_id");
print_r($name);
Should return this:
Array
(
[0] => Array
(
[name] => First Last
)
)
Another thing, I never put tick marks around values/variables in FQL.
$q = "SELECT name FROM user WHERE uid=$user_id";
$name = $facebook->api_client->fql_query($q);
But when you print the value you should put single quotes around the reference to the named index (in this case, 'name') and you should not wrap it all in double quotes:
echo "Name : " . $name[0]['name'];
