It's not a problem but i would like to learn how to get some other value.
function search_autocomplete($string) {
$matches = array();
$temp= array();
$query = db_select('user','s');
$return = $query
->fields('s')
->condition('lastname', '%' . db_like($string) . '%', 'LIKE')
->range(0, 10)
->execute();
foreach ($return as $row) {
$matches[$row->user_id] = check_plain($row->lastname).' '.($row->firstname);
}
drupal_json_output($matches);
}
Now when search box appears when i start typing by last name i get user lets say Doe John. But when i press search button i get his user_id.
I know when i change user_id to lets say last name i get the last name when i search.
Now my question is how to get last and first name when search is clicked, but send the user_ID.
The entity reference module handles it by putting the uid in brackets after the name:
foreach ($return as $row) {
$key = check_plain($row->lastname).' '.($row->firstname).' ('.$row->user_id].')';
$matches[$key] = check_plain($row->lastname).' '.($row->firstname);
}
Another (but more complex) option would be to create a hidden field to store the uid in.

I am using the gravity form on my site. I am working on create the custom report for this I have need gravity form fields name and id based on specific form id.Please let me know how I can do it.
I am using the following function but it is showing all forms info based on it. it is looking very hard to parse it. Please let me know any function so I can get fields name easily.
$forms = RGFormsModel::get_forms_by_id(13);
try this
function get_all_form_fields($form_id){
$form = RGFormsModel::get_form_meta($form_id);
$fields = array();
if(is_array($form["fields"])){
foreach($form["fields"] as $field){
if(isset($field["inputs"]) && is_array($field["inputs"])){
foreach($field["inputs"] as $input)
$fields[] = array($input["id"], GFCommon::get_label($field, $input["id"]));
}
else if(!rgar($field, 'displayOnly')){
$fields[] = array($field["id"], GFCommon::get_label($field));
}
}
}
//echo "<pre>";
//print_r($fields);
//echo "</pre>";
return $fields;
}
It's not that hard to parse:
$fields=array();
foreach ( $forms['fields'] as $field ) {
$fields[]=array($field['id'] => $field['inputName']);
}
P.S. I'm assuming you use Gravity Forms < 1.7 as RGFormsModel::get_forms_by_id is a deprecated function since 1.7
// Get the Form fields
$form = RGFormsModel::get_form_meta($form_id);
// Run through the fields to grab an object of the desired field
$field = RGFormsModel::get_field( $form, $field_id );
I use the above to get a specific field I want to filter the value of. The $field contains an object with all the properties you want.
echo $field->label // Gets the label
echo $field->inputName // Gets the name
echo $field->type // Gets the type
echo $field->cssClass // Gets the CSS Classes as a string
You are able to get the entered value/content of a field by using rgpost() and by referencing the id ($field->id).
// Check the entered value of every field
foreach( $form['fields'] as &$field ) {
// Get the content for the specific field
$fieldContent = rgpost( "input_".$field->id );
// Check the content
if ( $fieldContent == ... ){}
}
I'm trying to retrieve all the attachment of a specific post, but it doesn't work for the moment. Here is the code :
$args = array(
'post_type' => 'attachment',
'posts_per_page' => -1,
'post_parent' => $id
);
$attachments = get_posts($args);
Where Id is the id of my post. I've tried also with new WP_Query() but it didn't worked neither. Both ways return an empty result.
Does anyone have an idea what I'm doing wrong here ?
Thanks
EDIT
Ok, I think I know what's going wront.
When using this arguments for the get_posts function, it will return the images uploaded through the "Add a media" button in the specific post.
So basically, let's say that on my first post, I've uploaded all the images I would need for all my future post. If I apply the request on the first post, I will retrieve all the images, even the one that I don't use in this post.
If I apply this function to another post, because I didn't uploaded any file in this post, the function will retrieve an empty array.
Does anyone have an idea how I can retrieve all the images used in a specific post ? So not only uploaded, but really integrated into the post or added to a custom field ?
Thanks
When using get_posts to fetch attachments, you need to set post_status to inherit. Also, check out the get_children function:
$args = array(
'post_type' => 'attachment',
'post_mime_type' => 'image',
'numberposts' => -1,
'post_status' => 'inherit',
'post_parent' => $id
);
$attachments = get_children( $args );
Case: using ACF, I created an repeater field 'resort_pics' for my gallery, which has 2 fields 'picture_title' as text and 'picture' as an picture type.
Then happily uploaded 100 photos, some of them were same for several posts so I only clicked those from uploaded gallery (I will use term of "referenced images" for those).
Problem : then one happy day I noticed all "referenced images" are missing in our api.
Cause :
As noted at documentation comment from 'Uriahs Victor' (https://developer.wordpress.org/reference/functions/get_attached_media/)
Important to note that this function only returns the attachments that
were first uploaded/added to the post. Uploading an image to Post A(ID
1) and then adding that image later to Post B(ID 2) would give an
empty array if the following code was used:
$media = get_attached_media( 'image', 2 );
var_dump( $media );
Real cause :
Real source of all this problem is The thing that information about "reference images" are not stored in 'wp_posts' table but are actually stored in 'wp_postmeta', so by just querying 'wp_posts' table or using get_attached_media() which only looks there also you will not get all attachements for post.
Solution :
Lets take an example of post with ID - $postId which has defined
repeater - 'resort_pics', field in repeater with image 'picture'. (created with ACF plugin)
First get all attachements for our post (resort) (including images/pdfs and so on) with classic way (can be also used 'get_attached_media'):
$images = $wpdb->get_results("select ID,guid from wp_posts where post_parent = " . $postId . " and `post_type`= 'attachment'");
where guid is 'url' to an attachement, lets index those in array where key will be post id of an attachement
$mapImages = [];
foreach ($images as $image) {
$mapImages[$image->ID] = $image->guid;
}
Now we have all atachements but are missing all referenced images/files.
Lets continue by selecting all meta for our post (resort).
$metas = $wpdb->get_results("select meta_key,meta_value from wp_postmeta where post_id=" . $postId);
And index them by an meta key
$mapMetas = [];
foreach ($metas as $meta) {
$mapMetas[$meta->meta_key] = $meta->meta_value;
}
Lets say our post ($postId) has an 9 entries in 'resort_pics' with an image uploaded to its 'picture' field, then $mapMetas['resort_pics'] will have an value of 8.
Now the way how repeater fields keys are stored in $mapMetas array, is actually an :
'resort_pics_0_picture' -> itsPostId (5640 for example)
'resort_pics_1_picture' -> itsPostId (5641 for example)
'resort_pics_2_picture' -> itsPostId (5642 for example)
...
'resort_pics_8_picture' -> itsPostId (5648 for example)
Knowing this we can get simply all image urls for "resort_pics"
for ($i = 0; $i < $mapMetas['resort_pics']; $i++) {
$picture = [];
$picture['name'] = $mapMetas['resort_pics_' . $i . '_picture_title'];
$picture['url'] = $mapImages[$mapMetas['resort_pics_' . $i . '_picture']];
$pictures[] = $picture;
}
You may already get to this point, simply from $mapMetas get image ID and using it get an image url from $mapImages.
Lets say 'resort_pics_1_picture' is 'referenced' one (not directly uploaded image), we have its id '5641' but since its not connected to our $postID but to some other post id when it was actually uploaded. Its missing in our $mapImages array, so lets edit this code a bit.
for ($i = 0; $i < $mapMetas['resort_pics']; $i++) {
$picture = [];
$picture['name'] = $mapMetas['resort_pics_' . $i . '_picture_title'];
$picture['url'] = getAttachmentOrItsReferenceUrl('resort_pics_' . $i . '_picture', $mapImages, $mapMetas);
$pictures[] = $picture;
}
We have added an getAttachementOrItsReferenceUrl() method, which will simply first check if we already have this image (all uploaded to this post) and if not will fetch image data by its post id from 'wp_posts' table..
function getAttachmentOrItsReferenceUrl($code, $allAttachmentById, $allPostMetaByKey) {
global $wpdb;
$attachmentUrl = $allAttachmentById[$allPostMetaByKey[$code]];
if($attachmentUrl === null && isset($allPostMetaByKey[$code]) && $allPostMetaByKey[$code] !== '') {
$attachments = $wpdb->get_results("select ID,guid from wp_posts where ID = " . $allPostMetaByKey[$code]);
foreach ($attachments as $image) {
return $image->guid;
break;
}
} else {
return $attachmentUrl;
}
return "";
}
Finnal thoughts :
If you know your fields structure you can build up its key pretty straightforward
For an example
'rooms' repeater which has inside 'room_gallery' repeater which has inside 'image' image field.
'rooms_0_room_gallery_0_image'
--
$mapMetas['rooms'] - number of rooms
$mapMetas['rooms_' . $i . '_room_gallery'] - number of gallery images for room
--
'rooms_' . $i . '_room_gallery_' . $j . '_image'
How heavy is it ? Not really, if you are like me, having only small amount of referenced images you wont even feel it. All we added to load is an one meta query for an post, if no images are referenced that's all, then for every referenced image there is one more query, but its query on ID should be fast. There is a lot of way how to make load less, for example not do query for every single missing image, but do single query at the end with 'where in (id1,id2..)' to have single query to get all, or after fetching new image data, store it in some global array by its id, and check this array before fetching image for next posts (so if one image is stored in 200 posts, and you are fetching all it would make only 1 query), you got the point I leave it just at the ideas since this is bloody long post even without that :)
Hope this will help anybody in future.
i am currently using contact form 7 for wordpress. i would like a unique id for every form filled in and sent.
i have had a look around the internet but cant find anything, although i did find the following:
http://contactform7.com/special-mail-tags/
would there be any easy way to make my own function to do something similar to the above tags? i would need it to be a function to go into my themes function file, so that plugin updates wont affect it.
Cheers Dan
[_serial_number] field is an auto-incremented form submission ID. You just have to have Flamingo plugin installed as well. See http://contactform7.com/special-mail-tags/
(It's the same link as in the question, I guess the field wasn't there when the question was asked).
To generate ID for the Contactform7 you need to hook the 'wpcf7_posted_data'.
However, to generate incremental ID you need to save the forms in database so you can retrieve which ID should be next on next Form submit. For this you will need CFDB plugin (https://cfdbplugin.com/).
If you dont want to put the code inside theme functions.php file, you can use this plugin instead: https://wordpress.org/plugins/add-actions-and-filters/
Example code:
function pk_generate_ID($formName, $fieldName) {
//Retrieve highest ID from all records for given form stored by CFDB, increment by 1 and return.
require_once(ABSPATH . 'wp-content/plugins/contact-form-7-to-database-extension/CFDBFormIterator.php');
$start = '001';
$exp = new CFDBFormIterator();
$atts = array();
$atts['show'] = $fieldName;
$atts['filter'] = "$fieldName>=$start&&$fieldName<999999999999"; //is_numeric() is not permitted by default for CFDB filter
$atts['limit'] = '1';
$atts['orderby'] = "$fieldName DESC";
$atts['unbuffered'] = 'true';
$exp->export($formName, $atts);
$found = $start;
while ($row = $exp->nextRow()) {
$row2 = $row[$fieldName];
$row2 += 1;
$found = max($found,$row2);
}
return $found;
}
function pk_modify_data( $posted_data){
$formName = 'Form1'; // change this to your form's name
$fieldName = 'ID-1'; // change this to your field ID name
//Get title of the form from private property.
$cf_sub = (array) WPCF7_Submission::get_instance();
$cf = (array) $cf_sub["\0WPCF7_Submission\0contact_form"];
$title = (string) $cf["\0WPCF7_ContactForm\0title"];
if ( $posted_data && $title == $formName) ) { //formName match
$posted_data[$fieldName] = pk_generate_ID($formName, $fieldName);
}
return $posted_data;
}
add_filter('wpcf7_posted_data', 'pk_modify_data');
There is a checkbox added in user profile form, subscribe to daily newsletter. I want to get list of users who have subscribed (checkbox ON) and send them daily newsletter. How can I do this in drupal-6. (1) to get list of all subscribed users (2) Send them Email.
If you can explain at code level, I 'll really appreciate that.
If your profile field is profile_newsletter, your :
<?php
function mymodule_get_subscribers() {
$query = 'select * from {profile_fields} where `name`="%s";';
$result = db_query($query,'profile_newsletter');
$field = db_fetch_object($result);
$user_query = 'select * from {profile_values} where `fid`=%d and `value`=1;';
$result = db_query($user_query,$field->fid);
$subscribers = array();
while($subscriber = db_fetch_object($result)) {
$subscribers[] = $subscriber->uid;
}
return $subscribers; // Your array of subscriber user IDs
}
?>
This code was quick, is untested and should probably contain a few sanity-checks. But it should work.
For the sending of newsletters and such I'd recommend using a pre-rolled module. I haven't tried any for Drupal, but Simplenews seems to do the trick. http://drupal.org/project/simplenews
If nothing else it probably contains a good sending-function. Otherwise just use PHP mail()-function.
function your_custom_function ($user_id, "Field you want to get") {
$result = db_query("SELECT t2.value FROM profile_fields t1, profile_values t2 where
t1.title='Field you want to get' and t2.uid=".$user_id." and t1.fid=t2.fid");
$field = db_fetch_object($result);
$profile_type =$field->value;
return $profile_type;
}
I needed to create a custom select list for the user registration page that pulls a SQL query from nodes I need to link to users. I have successfully accomplished this task.. :)
However, when I submit the value, I can't seem to control where the value is stored. In fact, I can't store the value at all. I have created a custom field for my value, but only the new field name is stored, and it is serialized and stored in the Data column of the user table.
Below is my code, I've commented my issues in it. Any help would be appreciated!
<?php
// $Id$
//create the additional user form field, a select list named "account_name"
//then calls the next function to populate it.
function accountselect_user($op, &$edit, &$account, $category = NULL) {
if ($op == 'register' || 'edit')
$fields['Information']['account_name'] = array(
'#type' => 'select',
'#title' => 'Account',
'#description' => t('Select the account to which the contact belongs'),
'#options' => accountselect_getclubs() ,
);
return $fields;
}
//contains query to pull results to select list...this part is working
function accountselect_getclubs() {
$return = array();
$sql = 'SELECT DISTINCT `title` FROM node WHERE type = \'accounts\' ';
$result = db_query($sql);
while ($row = db_fetch_array($result)) {
$return[] = $row['title'];
}
return $return;
}
//CAN'T GET THIS PART TO WORK - query to update the row - the uid = 29 is for
//testing puposes. Once I get the test value to work
//the test value I will worry about updating the correct user.
function accountselect_submitaccount() {
$sql = "UPDATE users SET account = \'value\' WHERE uid = \'29\'";
db_query($sql);
drupal_set_message(t('The field has been updated.'));
}
//I SUSPECT THE PROBLEM IS HERE...call the submitaccount function.
//I have tried hook_form_alter as well...
function accountselect_submit(&$form, &$form_state) {
if($form_id == 'user-register')
drupal_execute('accountselect_submitaccount');
}
Have you checked Drupal's logs? It should be throwing errors, as this is not a valid query.
$sql = "UPDATE users SET account = \'value\' WHERE uid = \'29\'";
Should be:
$sql = "UPDATE users SET account = 'value' WHERE uid = '29'";
Additionally, in:
function accountselect_submit(&$form, &$form_state) {
if($form_id == 'user-register')
drupal_execute('accountselect_submitaccount');
}
$form_id is never defined.
You say you've created the field in the database, but it must match the name of the Drupal field to be automatically handled. You've got two different names for it - account_name in the Drupal field, but account in the database. Make them consistent and it should be automatically handled, no submit functions required.
