i have a field in table like this,
i have a code like this,
public function get_data_promocode($db) {
$date = date('Y-m-d H:i:s');
$this->db->from($db);
$this->db->where('promo_start >=', date('Y-m-d 00:00:00',strtotime($date)));
$this->db->where('promo_end <=', date('Y-m-d 23:59:59',strtotime($date)));
$this->db->where('promo_count IS NULL', null, false);
$this->db->order_by('promo_id DESC');
$query = $this->db->get();
return $query->result();
}
how to display promo data that is still on when the current date is between promo_start and promo_end?
get your promo_start_date and promo_end_date and pass those variables with your method
$this->db->where("promo_end >= '" . $promo_start_date . "' AND promo_start <= '" . $promo_end_date . "'")

I would like to customize my wordpress search page
First, i used the "posts_where" to modify the clause
function search_posts_where ($where) {
global $wp_query, $wpdb;
// Searching and not in admin
if (!is_admin() && $wp_query->is_search && isset($wp_query->query_vars['s'])) {
// Tables names
$post_title = "{$wpdb->prefix}posts.post_title";
$post_excerpt = "{$wpdb->prefix}posts.post_excerpt";
$post_content = "{$wpdb->prefix}posts.post_content";
$post_type = "{$wpdb->prefix}posts.post_type";
$post_status = "{$wpdb->prefix}posts.post_status";
$post_author = "{$wpdb->prefix}posts.post_author";
$post_ID = "{$wpdb->prefix}posts.ID";
$post_date = "{$wpdb->prefix}posts.post_date";
// Get the 's' parameters
$wp_query->query_vars['s'] ? $search_text = $wp_query->query_vars['s'] : $search_text = 'IS NULL';
// Write the where clause
$where = " AND ((($post_title LIKE '%$search_text%')";
$where .= " OR ($post_excerpt LIKE '%$search_text%')";
$where .= " OR ($post_content LIKE '%$search_text%')))";
$where .= " AND $post_type IN ('parcours')";
$where .= " AND $post_status = 'publish'";
$where .= " GROUP BY $post_ID";
}
return $where;
}
add_filter('posts_where', 'search_posts_where', 10, 2);
It works fine. All posts belonging to my custom post type 'parcours' are shown, depending on what I entered for the 's' query.
Second, i used the "posts_join" to add the meta table (not used yet !)
function search_posts_join ($join) {
global $wp_query, $wpdb;
// Searching and not in admin
if (!is_admin() && $wp_query->is_search && isset($wp_query->query_vars['s'])) {
// Tables names
$post_meta = "{$wpdb->prefix}postmeta";
$post_ID = "{$wpdb->prefix}posts.ID";
$post_meta_ID = "{$wpdb->prefix}postmeta.post_id";
// Join clause
$join .= "LEFT JOIN $post_meta ON ($post_ID = $post_meta_ID)";
}
return $join;
}
add_filter('posts_join', 'search_posts_join', 10, 2);
Still works perfectly !
Now the problem, i would like to order my posts in ascending direction (default is descending). So, i added the "posts_orderby" hook.
function search_posts_orderby ($orderby) {
global $wp_query, $wpdb;
// Searching and not in admin
if (!is_admin() && $wp_query->is_search) {
// Tables names
$post_title = "{$wpdb->prefix}posts.post_title";
$post_date = "{$wpdb->prefix}posts.post_date";
$post_ID = "{$wpdb->prefix}posts.ID";
// Order by clause
$orderby .= " ORDER BY $post_title ASC,";
$orderby .= " $post_date DESC";
}
return $orderby;
}
add_filter('posts_orderby', 'search_posts_orderby', 10, 2);
And here is the problem. All posts disapeared. Removing the "orderby" and they come back.
Looking at the SQL query, i have
"SELECT SQL_CALC_FOUND_ROWS wp_128444_posts.* FROM wp_128444_posts LEFT JOIN wp_128444_postmeta ON (wp_128444_posts.ID = wp_128444_postmeta.post_id) WHERE 1=1 AND (((wp_128444_posts.post_title LIKE '%tour%') OR (wp_128444_posts.post_excerpt LIKE '%tour%') OR (wp_128444_posts.post_content LIKE '%tour%'))) AND wp_128444_posts.post_type IN ('parcours') AND wp_128444_posts.post_status = 'publish' GROUP BY wp_128444_posts.ID ORDER BY wp_128444_posts.post_title LIKE '{5a35f6e9144541f93e08829126b2cb633436cebf95d774062fff749a12e6a465}tour{5a35f6e9144541f93e08829126b2cb633436cebf95d774062fff749a12e6a465}' DESC, wp_128444_posts.post_date DESC ORDER BY wp_128444_posts.post_title ASC, wp_128444_posts.post_date DESC LIMIT 0, 6"
I don't know why WP is adding the default ORDER BY, that i don't want.
Is is possible to remove it ?
I tried to replace my hook with "pre_get_posts" hook
function order_posts_by_title( $query ) {
if ( $query->is_search() && $query->is_main_query() ) {
$query->set( 'orderby', 'title' );
$query->set( 'order', 'ASC' );
}
}
add_action( 'pre_get_posts', 'order_posts_by_title' );
With this hook, it works !! Sounds very strange to me
Any explanation ?
Thanks
I am trying to translate this query to CActiveDataProvider:
// SELECT p.id "
// . "FROM projects AS p "
// . "LEFT JOIN purged_files AS pf ON p.id = pf.project_id "
// . "WHERE pf.id IS NULL "
// . "AND `new_status_id` IN ('DELIVERED', 'PAID') "
// . "AND `created` <= '" . date("Y-m-d H:i:s", strtotime("-" . $lifetime_days . " DAYS")) . "' "
// . "ORDER BY id DESC "
// . "LIMIT 0, 5000")
Current code:
$criteria->select = "project.id";
$criteria->join = 'LEFT JOIN purged_files ON project.id = purged_files.project_id';
$criteria->order = "project.id desc";
$criteria->condition = "`new_status_id` IN ('DELIVERED', 'PAID') AND `created` <= '" . date("Y-m-d H:i:s", strtotime("-180 DAYS")) . "'";
$criteria->limit = 5000;
$criteria->offset = 0;
$dataProvider = new CActiveDataProvider('Project', array(
'criteria' => $criteria,
));
$iterator = new CDataProviderIterator($dataProvider);
foreach ($iterator as $project) {
echo $project->id . "<br>";
}
var_dump('<pre>', "end", '</pre>');die;
When I run this I am getting this error:
CDbCommand failed to execute the SQL statement: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'project.id' in 'on clause'. The SQL statement executed was: SELECT COUNT(*) FROM `projects` `t` LEFT JOIN purged_files ON project.id = purged_files.project_id WHERE (`t`.`status` <> "DELETED" AND `t`.`status` <> "CANCELED" AND `t`.`status` <> "ARCHIVED") AND (`new_status_id` IN ('DELIVERED', 'PAID') AND `created` <= '2017-12-29 13:31:42')
What seems to be the issue here?
You're using incorrect alias in your conditions. Main model table is aliased as t, so either you should use t as alias in your condition instead of project:
$criteria->order = "t.id desc";
Or overwrite alias in criteria:
$criteria->alias = 'project';
I would like to use PDO for selecting (searching) a database.
The search 'form' has MULTIPLE fields that can be used.. 1 or many can be filled in to help refine the search. (or there can be many o them left blank/empty)
here is what I have been using (locally):
//localhost details
$db_username="root"; //database user name
$db_password="";//database password
$db_database="test"; //database name
$db_host="localhost";
mysql_connect($db_host,$db_username,$db_password);
#mysql_select_db($db_database) or die("Unable to connect to database.");
if(isset($_POST['submit'])) {
// define the list of fields
$fields = array('first', 'trialdate', 'wcity', 'wstate', 'plantif');
$conditions = array();
//loop through the defined fields
foreach($fields as $field){
// if the field is set and not empty
if(isset($_POST[$field]) && $_POST[$field] != '') {
// create a new condition while escaping the value inputed by the user (SQL Injection)
$conditions[] = "`$field` LIKE '%" . mysql_real_escape_string($_POST[$field]) . "%'";
}
}
//build the query
$query = "SELECT * FROM myTable ";
// if there are conditions defined
if(count($conditions) > 0) {
// append the conditions
$query .= "WHERE " . implode (' OR ', $conditions); // you can change to 'OR', but I suggest to apply the filters cumulative
}
$result = mysql_query($query);
if(isset($_POST['submit'])) {
while($row = mysql_fetch_array($result)) {
echo $row['first'] . "<br />"; //individual value
//build panels that displays everything from row..etc
}
}
}
this has been working fine... but I'd like convert to using the PDO approach.
I gave it a few tries...but am missing something here..
heres what I've tried so far..
//localhost details
$db_username="root"; //database user name
$db_password="";//database password
$db_database="test"; //database name
$db_host="localhost";
//PDO DB connection
$conn = new PDO('mysql:host='.$db_host.'dbname='.$db_database.'charset=utf8', $db_username, $db_password);
if(isset($_POST['submit'])) {
$stmt = $conn->prepare('SELECT * FROM myTable WHERE first LIKE :first OR trialdate LIKE :trialdate OR wcity LIKE :wcity OR wstate LIKE :wstate OR plantif LIKE :plantif');
//build query placeholders (*note: use bindValue for $_POST values)
$stmt->bindValue(':first', '%' . $_POST['first'] . '%');
$stmt->bindValue(':trialdate', '%' . $_POST['trialdate'] . '%');
$stmt->bindValue(':wcity', '%' . $_POST['wcity'] . '%');
$stmt->bindValue(':wstate', '%' . $_POST['wstate'] . '%');
$stmt->bindValue(':plantif', '%' . $_POST['plantif'] . '%');
$stmt->execute();
foreach ($stmt as $row) {
// do something with $row
echo $row['first'] . "<br />"; //individual value
}
}
I could use help on getting the PDO example working with a displayed result/row/value?
The following function gives all the related data except artist_id, when run I have checked all elements in the database and ok.
If I change the artist_id to an actual 'id' it shows in the result of the function as WHERE artist_id = 4 AND........
Confess I do not understand what is causing this.
Result of the function:
SELECT `image_album_id`, `member_id`, `artist_id`, `albumname`, `ext`, `timestamp`
FROM album_images WHERE artist_id = AND member_id = 1 AND
image_album_id = 160
<?php
function get_data_nxtprv($fields, $where) {
$return = FALSE;
// Template
$template = "SELECT %s "
. "FROM album_images "
. "WHERE artist_id = " . $artist_id. "
AND member_id = ".$_SESSION['member_id']." %s";
// Current record
$sql = sprintf($template, $fields, $where);
$query = mysql_query($sql);
$query_result = mysql_fetch_assoc($query);
//print_r($sql);
// If data has been found
if ($query_result)
{
$return = $query_result;
}
return $return;
?>
I am not entirely sure I understand your question. But I noticed that your function uses three input variables:
$artist_id, $fields, $where
But $artist_id is not getting passed as an argument.
You would need to modify the function call:
function get_data_nxtprv($artist_id, $fields, $where)
There is an error in your SQL
SELECT `image_album_id`, `member_id`, `artist_id`, `albumname`, `ext`, `timestamp`
FROM album_images WHERE artist_id = AND member_id = 1 AND
image_album_id = 160
should it not be
SELECT `image_album_id`, `member_id`, `artist_id`, `albumname`, `ext`, `timestamp`
FROM album_images WHERE member_id = 1 AND
image_album_id = 160
if artist_id is one of the fields you're looking for?
i have a php file that works OK.
That php makes recursive search in a local folder, and calculates the last modification DATE of those files.
My question: Every time that i open that php file i want that date to be stored in a SQL table.
-i have created a table with 2 columns (ID, date) where ID=1 then go and update the date field.
but how can i call FROM php file to save the date into sql field?
My php file:
<?php
// LAST FILES UPDATE
function getAllFiles($directory, $recursive = true) {
$result = array();
$handle = opendir($directory);
while ($datei = readdir($handle))
{
if (($datei != '.') && ($datei != '..'))
{
$file = $directory.$datei;
if (is_dir($file)) {
if ($recursive) {
$result = array_merge($result, getAllFiles($file.'/'));
}
} else {
$result[] = $file;
}
}
}
closedir($handle);
return $result;
}
function getHighestFileTimestamp($directory, $recursive = true) {
$allFiles = getAllFiles($directory, $recursive);
$highestKnown = 0;
foreach ($allFiles as $val) {
$currentValue = filemtime($val);
if ($currentValue > $highestKnown) $highestKnown = $currentValue;
}
return $highestKnown;
}
echo '<div align="center" style=" padding-top:5px; margin-top:5px; border-top:dotted #777; border-width:1px;">Last Update Date:<br>';
date_default_timezone_set('Europe/Athens');
setlocale(LC_ALL, array('el_GR.UTF-8','el_GR#euro','el_GR','greek'));
echo strftime('%d %b %Y, %H:%M:%S', getHighestFileTimestamp('../'));
echo '</div>';
$host="localhost"; // Host name
$username="..."; // Mysql username
$password="..."; // Mysql password
$db_name="..."; // Database name
$tbl_name="..."; // Table name
// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// update data in mysql database
$sql="UPDATE $tbl_name SET date='HUMMMM HERE HOW TO PULL THE VALUE?' WHERE id='1'";
$result=mysql_query($sql);
// if successfully updated.
if($result){
echo "Successful";
echo "<BR>";
}
else {
echo "ERROR";
}
?>
Try something like this:
// use the function to calculate highest timestamp
$highestdate = getHighestFileTimestamp("../");
// Insert the highest timestamp into the db
$sql= sprintf("UPDATE $tbl_name SET date='%s' WHERE id='1'",
$highestdate);
--EDIT-- merged with Hiroto's answer
You can use these other styles to concatenate string constants with variables
$sql = "UPDATE {$tbl_name} SET date='{$date}' WHERE id='{$id}';";
Or, you could use concatenation.
$sql = "UPDATE " . $tbl_name . " SET date='" . $date . "' WHERE id='1';";
$sql = "UPDATE {$tbl_name} SET date='{$date}' WHERE id='{$id}';";
Or, you could use concatenation.
$sql = "UPDATE " . $tbl_name . " SET date='" . $date . "' WHERE id='1';";
