How can I query the wordpress database so that I'm only display the number of posts from a certain category starting at a certain date?
I’ve tried something like this but it doesn’t work:
<?php
$user_count = $wpdb->get_var( "SELECT COUNT(*) FROM $wpdb->posts WHERE term_id = '4' AND post_date >= '2014-01-01 00:00:00' " );
echo "<p>User count is {$user_count}</p>";
?>
What am I doing wrong?
Use wordpress native WP-Query:
$args = array(
'post_type' => 'post',
'date_query' => array(
'year ' => 2015,
),
'cat' => 5,
'posts_per_page'=> -1
);
$query = new WP_Query( $args );
$numberOfPosts = $query->post_count;
$numberOfPosts should hold the number you are looking for. Just paste this where you used your original code which you've shared with us.
Read more here: https://codex.wordpress.org/Class_Reference/WP_Query
Excerpt from the above mentioned url:
posts_per_page (int) - number of post to show per page (available with Version 2.1, replaced showposts parameter). Use 'posts_per_page'=>-1 to show all posts (the 'offset' parameter is ignored with a -1 value). Set the 'paged' parameter if pagination is off after using this parameter. Note: if the query is in a feed, wordpress overwrites this parameter with the stored 'posts_per_rss' option. To reimpose the limit, try using the 'post_limits' filter, or filter 'pre_option_posts_per_rss' and return -1
You can find a bunch of other options there aswell to tweak your query, to get the desired result. This should give the result you want for now.

It's probably a stupid question but I'm trying to use $wpdb->update instead of $wpdb->query but I'm not sure how to use limit 1. So instead of
$wpdb->query("update {$wpdb->prefix}vp_pms_group_users set read = '1', seen = '1', time_seen = '{$date_time_seen}' where message_id = '{$last_message_id}' and group_id = '{$group_id}' and to_username = '{$session_uid}' and read = '0' limit 1");
I've tried with
$wpdb->update($wpdb->prefix . "vp_pms_group_users", array(
'read' => '1',
'seen' => '1',
'time_seen' => $date_time_seen,
),
array(
'message_id' => $last_message_id,
'group_id' => $group_id,
'to_username' => $session_uid,
'read' => '0',
),
LIMIT 1 //????
);
Should I use limit after the array or inside it?
Thanks.
Here's an answer, it's not pretty, but based on looking through the method chain within $wpdb it's possibly the only way to achieve what you're after, and still use $wpdb->update().
Step 1.
Make your update with a unique parameter which you'll later replace, note that this must be the last parameter passed to the WHERE clause, otherwise replacing it with LIMIT 1 will cause a syntax error in your SQL statement.
Something like:
$wpdb->update(
$wpdb->prefix . "vp_pms_group_users",
array(...),
array(
...
'MyReplacementLimit' => 1
)
);
This should give you an SQL statement like so:
UPDATE vp_pms_group_users SET ... WHERE ... AND MyReplacementLimit = 1;
Step 2:
Now you can use the query filter to replace that fake clause with a limit...
add_filter('query', function ($query) {
return str_replace('AND MyReplacementLimit = 1', 'LIMIT 1', $query);
});
This is untested and is based purely on reading through the code available in $wpdb. It may need a few tweaks to get working correctly.
A simpler solution:
You could always just use SQL directly, so long as you're using $wpdb->prepare() it's probably easier to read, and more understandable than the above approach.
you should change Previous answer add_filter to this:
add_filter('query', function ($query) {
return str_replace("AND `MyReplacementLimit` = '1'", 'LIMIT 1', $query);
});
I want to use ACF frontend form function to create a form with custom fields
I see this issue for create new term, #Alhana
ACF front end form to create term
but I want to generate the form with old data
Well, i didn't see that question, but if it's still actual, here's a solution.
First of all, make sure you have ACF group, linked to your taxonomy. You will need ID of this group, it can be found in url on group edit page, for example:
http://site.ru/wp-admin/post.php?post=340&action=edit
In this case group ID is 340. If you don't want to use hardcoded ID (if your groups are changing from time to time), you can get it, using group name (in this example group name is Technic CPT):
global $wpdb;
$group_ID = $wpdb->get_var( "SELECT ID FROM $wpdb->posts WHERE post_title = 'Technic CPT'" );
Then, you'll need ID of term you're updating. I think, it's not nesessary to write about getting it since it's WP basics :) You'll end with something like this:
$term_id = 405;
And finally, you'll need your taxonomy's slug. In this example it's technic. So, let's render our form!
acf_form_head();
$acf_form_args = array(
'id' => 'technic_edit_form',
'post_id' => 'technic_'.$term_id,
'form' => true,
'submit_value' => 'Update technic',
'field_groups' => array($group_ID),
'updated_message' => 'Technic is updated!';
);
acf_form( $acf_form_args );
Now your term's custom fields will be shown in this form. But to save term data after editing you'll need to add some more code. ACF form assumes that you're saving post data, we'll add some logic to detect saving data for term.
add_filter( 'acf/pre_save_post', 'acf_handle_form_save', 10, 1 );
function acf_handle_form_save( $post_id ) {
// Function accepts id of object we're saving.
// All WordPress IDs are unique so we can use this to check which object it is now.
// We'll try to get term by id.
// We'll get term id with added taxonomy slug, for example 'technic_405'.
// For checking term existence we must cut out this slug.
$cut_post_id = str_replace( 'technic_', '', $post_id );
$test_tax_term = get_term_by( 'id', $cut_post_id, 'technic' );
// If $test_tax_term is true - we are saving taxonomy term.
// So let's change form behaviour to saving term instead of post.
if ( $test_tax_term ) :
// Get array of fields, attached to our taxonomy
global $wpdb;
$group_ID = $wpdb->get_var( "SELECT ID FROM $wpdb->posts WHERE post_title = 'Technic CPT'" );
$acf_fields = acf_get_fields_by_id( $group_ID );
// Then sanitize fields from $_POST
// All acf fields will be in $_POST['acf']
foreach ( $acf_fields as $acf_field ) :
$$acf_field[ 'name' ] = trim( esc_attr( strip_tags( $_POST[ 'acf' ][ $acf_field[ 'key' ] ] ) ) );
endforeach;
// We need to have some fields in our group, which are just duplicates of standard term fields: name, slug, description.
// In this example it's only one field - term name, called 'technic_name'.
$name = 'technic_name';
// Update base term info, in this example - only name.
$term = wp_update_term( $cut_post_id, 'technic', array( 'name' => $$name ) );
// If all is correct, update custom fields:
if ( !is_wp_error( $term ) ) :
foreach ( $acf_fields as $acf_field ) :
update_field( $acf_field[ 'name' ], $$acf_field[ 'name' ], 'technic_' . $cut_post_id );
endforeach;
endif;
else :
// Here is saving usual post data. Do what you need for saving it or just skip this point
endif;
return $post_id;
}
Please note: validation of $_POST data may be more complex. For example, you may have to validate array of values if there are ACF galleries or relationships among your taxonomy fields. In my example i have only common text fields.
Hope that helps!
The answer from Alhana worked for me with one change. The term object works if sent as the the value for the post_id:
$term_obj = get_term($term_id);
$acf_form_args = array(
'post_id' => $term_obj,
'post_title' => false,
'submit_value' => 'Update Term',
'field_groups' => array($group_ID),
);
global $wp_query; $args = array_merge( $wp_query->query_vars, array( 'meta_value' => 'pro') );
query_posts( $args );
i have 2 meta value pro and free i want to pass both in query/ or i want it order by pro with random order. i try to use , coma but not getting any solution .
query_posts($query_string . '&orderby=rand'); i pass this but i got all value random but what i want. i want pro first and then free
i pass this in in built theme. so when i pass pro i got pro value and when i pass free i got free value but i want both with pro list display first then free list and its random. order.. thanks
In Wordpress post query you can order your posts by meta value. So, you can order with your meta key/values (0-9) or (A-Z).
You will use (A-Z) sorting.
$query = array( 'meta_key' => 'your_meta_key', 'orderby' => 'meta_value_num', 'order' => 'ASC' );
I'm trying to use the "HAVING" clause in a SQL query using the CakePHP paginate() method.
After some searching around it looks like this can't be achieved through Cake's paginate()/find() methods.
The code I have looks something like this:
$this->paginate = array(
'fields' => $fields,
'conditions' => $conditions,
'recursive' => 1,
'limit' => 10,
'order' => $order,
'group' => 'Venue.id');
One of the $fields is an alias "distance". I want to add a query for when distance < 25 (e.g. HAVING distance < 25).
I have seen two workarounds so far, unfortunately neither suit my needs. The two I've seen are:
1) Adding the HAVING clause in the "group" option. e.g. 'group' => 'Venue.id HAVING distance < 25'. This doesn't seem to work when used in conjunction with pagination as it messes up the initial count query that is performed. (ie tries to SELECT distinct(Venue.id HAVING distance < 25) which is obviously invalid syntax.
2) Adding the HAVING clause after the WHERE condition (e.g. WHERE 1 = 1 HAVING field > 25) This doesn't work as it seems the HAVING clause must come after the group statement which Cake is placing after the WHERE condition in the query it generates.
Does anyone know of a way to do this with CakePHP's find() method? I don't want to use query() as that would involve a lot of rework and also mean I'd need to implement my own pagination logic!
Thanks in advance
You have to put it with the group conditions. like this
$this->find('all', array(
'conditions' => array(
'Post.length >=' => 100
),
'fields' => array(
'Author.id', 'COUNT(*) as Total'
),
'group' => array(
'Total HAVING Total > 10'
)
));
Hope it helps you
I used the following trick to add my own HAVING clause at the end of my WHERE clause. The "dbo->expression()" method is mentioned in the cake sub-query documentation.
function addHaving(array $existingConditions, $havingClause) {
$model = 'User';
$db = $this->$model->getDataSource();
// Two fun things at play here,
// 1 - mysql doesn't allow you to use aliases in WHERE clause
// 2 - Cake doesn't allow a HAVING clause separate from a GROUP BY
// This expression should go last in the WHERE clause (following the last AND)
$taut = count($existingConditions) > 0 ? '1 = 1' : '';
$having = $db->expression("$taut HAVING $havingClause");
$existingConditions[] = $having;
return $existingConditions;
}
As per the manual, CakePHP/2 supports having at last. It was added as find array parameter on version 2.10.0, released on 22nd July 2017.
From the 2.10 Migration Guide:
Model::find() now supports having and lock options that enable you to
add HAVING and FOR UPDATE locking clauses to your find operations.
Just had the same problem. I know, one is not supposed to modify the internal code but if you open the PaginatorComponent and you modify line 188:
$count = $object->find('count', array_merge($parameters, $extra));
to this:
$count = $object->find(
'count',
array_merge(array("fields" => $fields),$parameters, $extra)
);
Everything will be fixed. You will be able to add your HAVING clause to the 'group' and the COUNT(*) won't be a problem.
Or, make line:
$count = $object->paginateCount($conditions, $recursive, $extra);
to include the $fields:
$count = $object->paginateCount($fields,$conditions, $recursive, $extra);
After that, you can "override" the method on the Model and make sure to include the $fields in the find() and that's it!, =P
Here is another idea that doesn't solve the pagination issue, but it is clean since it just overrides the find command in AppModel. Just add a group and having element to your query and this will convert to a HAVING clause.
public function find($type = 'first', $query = array()) {
if (!empty($query['having']) && is_array($query['having']) && !empty($query['group'])) {
if ($type == 'all') {
if (!is_array($query['group'])) {
$query['group'] = array($query['group']);
}
$ds = $this->getDataSource();
$having = $ds->conditions($query['having'], true, false);
$query['group'][count($query['group']) - 1] .= " HAVING $having";
CakeLog::write('debug', 'Model->find: out query=' . print_r($query, true));
} else {
unset($query['having']);
}
}
return parent::find($type, $query);
}
Found it here
https://groups.google.com/forum/?fromgroups=#!topic/tickets-cakephp/EYFxihwb55I
Using 'having' in find did not work for me. Instead I put into one string with the group
" group => product_id, color_id having sum(quantity) > 2000 " and works like a charm.
Using CakePHP 2.9
I just created a data table based on a query and displayed it successfully using theme_table().
Now, I'd like to add some filters to the table but have no idea how to proceed.
Is there a built-in feature that allow me to do this easily, or should I manually add a form and update the query/redisplay the results each time the user selects something?
Thanks for your help!
I think you want to use pager_query and tablesort_sql: it's especially made for creating tables of data with pagination and sorting capabilities (and themes usually theme such tables nicely out of the box).
Example:
<?php
// The regular query without sorting or pagination parameters
$sql = 'SELECT cid, first_name, last_name, company, city FROM {clients}';
// Number of rows per page
$limit = 20;
// List of table columns ("field" is the matching database column from the sql query)
$header = array(
array('data' => t('Name'), 'field' => 'last_name', 'sort' => 'asc'),
array('data' => t('Company'), 'field' => 'company'),
array('data' => t('City'), 'field' => 'city')
);
// Calculates how to modify the SQL query according to the current pagination and sorting settings
// Then performs the database query
$tablesort = tablesort_sql($header);
$result = pager_query($sql . $tablesort, $limit);
$rows = array();
while ($client = db_fetch_object($result)) {
$rows[] = array(l($client->last_name.', '.$client->first_name, 'client/'.$client->cid), $client->company, $client->city);
}
// A message in case no results were found
if (!$rows) {
$rows[] = array(array('data' => t('No client accounts created yet.'), 'colspan' => 3));
}
// Then you can pass the data to the theme functions
$output .= theme('table', $header, $rows);
$output .= theme('pager', NULL, $limit, 0);
// And return the HTML output
print $output;
?>
(I added comments, but the original version of the example comes from this page)
Alternatively, maybe you don't need to make a module at all if you're just trying to make a page that displays a list of data, you may prefer using the Views module.
