I'm trying to add a new row in a wordpress table (that i've created), but every times that i add the new row, all the others are deleted and if i look DB table i can see only last inserted row.
I've tried two methods, but i get the same results:
$ins_reply = $wpdb->insert( $table, array('itemid'=> $item_id, 'time' => $time, 'title' => '', 'text' => $content, 'author' => $user, 'deadline' => 0));
OR
$query_insert = "INSERT INTO ".$table." (`itemid` ,`time` ,`title` ,`text` ,`deadline` ,`author`) VALUES ('".$item_id."', '".$time."', '', '".$content."', '0', '".$user."')";
$wpdb->query($query_insert);
What's wrong in my code?
Your query as posted in your question is not the source of your issue.
Perhaps you are working on a plugin where the table creation script is accidentally wiping & re-installing the table during this operation?

I have a table called posts that stores all the posts . It has two columns "Created" and "Modified" .
Below is my query in the model :
$options = [
'conditions' => [
'circle_id' => $my_circle_list,
'team_id' => $this->current_team_id,
'modified BETWEEN ? AND ?' => [$start, $end],
],
'order' => ['modified'=> 'desc'],
'limit' => $limit,
'fields' => ['post_id'],
];
$res = $this->find('list', $options);
Now i want the latest edited posts on top and below is what my mysql dump reads like :
SELECT `Post`.`id` FROM `db`.`posts` AS `Post` WHERE `Post`.`id` IN (125, 124) AND `Post`.`del_flg` = '0' ORDER BY `Post`.`modified` desc LIMIT 20
If i run this query in my database editor ,it gives my the correct output , but in my controller the ordering changes again , this is something i figured after i debugged the array values.
Would be helpful if anyone could tell me if there's any specific reason behind this . The call to this model method from the controller is done in a conventional manner .
When using $this->find() after Cake has queried the database with the generated SQL it calls the afterFind() method on the model where it can manipulate the data. This is the mostly likely place for the ordering to have been modified.
I an looking to use a JOIN to select data from a table and a view in CakePHP like so :
$this->Annonces->find('all')
->where($arrFiltres)
->order($arrOrder)
->join([
'table' => 'annonces_suivis',
'alias' => 'AnnoncesSuivis',
'conditions' => [...],
]);
And would like to be able to select all the fields from the first table and som of the jointed table like so :
->select(['Annonces.*', 'AnnoncesSuivis.id']);
But this creates a faulty SQL query.
.* isn't supported by the ORM Query, it will convert this to
Annonces.* AS Annonces__*
which is invalid SQL. It would work with the lower level Database Query (Connection::newQuery()), which doesn't add aliases, however it won't return entities, so that's probably not what you want.
See Cookbook > Database Access & ORM > Database Basics > \Cake\Database\Connection::newQuery()
Pass a table object
As of CakePHP 3.1 you can pass table objects to Query::select(), which will cause all the fields of the table to be selected.
$this->Annonces
->find('all')
->select(['AnnoncesSuivis.id'])
->select($this->Annonces)
->join([
'table' => 'annonces_suivis',
'alias' => 'AnnoncesSuivis',
'conditions' => [ /* ... */ ],
])
->where($arrFiltres)
->order($arrOrder);
That way the AnnoncesSuivis.id field, and all fields of Annonces will be selected.
See Cookbook > Database Access & ORM > Query Builder > Selecting All Fields From a Table
Build the fields from the schema
That's what passing a table object will cause internally too, and it's also supported in CakePHP < 3.1.
$query = $this->Annonces->find('all');
$fields = $query->aliasFields(
$this->Annonces->schema()->columns(),
$this->Annonces->alias()
);
$query
->select(array_merge(['AnnoncesSuivis.id'], $fields))
->join([
'table' => 'annonces_suivis',
'alias' => 'AnnoncesSuivis',
'conditions' => [ /* ... */ ],
])
->where($arrFiltres)
->order($arrOrder);
This would also work for the fields option that can be passed to Table::find(), though you'd have to use a separate query object in that case, like
$fields = $this->Annonces->query()->aliasFields(
$this->Annonces->schema()->columns(),
$this->Annonces->alias()
);
$this->Annonces->find('all', [
'fields' => array_merge(['AnnoncesSuivis.id'], $fields)
// ...
]);
Use Query::autoFields()
In ealier CakePHP version, you could also make use of Query::autoFields(), which, when set to true, will automatically include the fields of the main table and possible containments.
See Cookbook > Database Access & ORM > Retrieving Data & Results Sets > Passing Conditions to Contain
Auto selecting all fields is the default behavior until you set fields via Query::select(), in that case you'll have to explicitly enable Query::autoFields().
$this->Annonces
->find('all')
->select(['AnnoncesSuivis.id'])
->autoFields(true)
->join([
'table' => 'annonces_suivis',
'alias' => 'AnnoncesSuivis',
'conditions' => [ /* ... */ ],
])
->where($arrFiltres)
->order($arrOrder);
This should give you the desired query, however as mentioned this will only work for the main table and containments, if you'd wanted to include all fields of a manually joined table, then you'd have to specify them one by one.
You also can create virtual field in Entity:
namespace App\Model\Entity;
use Cake\ORM\Entity;
class User extends Entity {
protected function _getFullName() {
return $this->_properties['first_name'] . ' ' . $this->_properties['last_name'];
}
}
echo $entity->full_name;
I'm sorry, I am a newbie in CakePHP and I am a little bit confused in this subject, let me explain:
I have a relationship between two tables. One of the table is Dose and the other is tank. So, one Tank belongs to a Dose. A Dose has many Tanks. The table schema is:
CREATE TABLE `doses` (
`id` INT(10) NOT NULL AUTO_INCREMENT,
`dose` INT(5) NULL DEFAULT NULL,
PRIMARY KEY (`id`)
)
In my Tank view I have the following code:
<?php echo $form->input('dose_id', array('class'=>'input', 'label' => ''));?>
Each 'dose' (field) from Dose table correspond to a value, such as 200, 300, and so forth. I need to use these numbers to calculate others numbers before to insert into my database (table tank). For instance, my code in tanks_controllers:
$t_u = $this->data['Tank']['tipo_uso_id'];
if( $t_u == '1'){
$this->data['Tank']['producao_adubo_diaria'] = $this->data['Tank']['dose_id'] * 0.10;
.
.
.
However, it is bringing to me the ID of the Dose and not the value (dose field). Where can I set up this to bring me the correct data (dose)? I tried to set up this way in my model:
'Dose' => array(
'className' => 'Dose',
'foreignKey' => 'dose_id',
'conditions' => '',
'fields' => 'dose',
'order' => ''
)
It did not work.
I appreciate your time helping me.
Thanks in advance.

You need to get it from the db (model), not from the view. So you need to do a find(). If you are new to Cake, you should read the cookbook first to see how it works.
What does $form->input('dose_id') produce? A dropdown? If so; by default cake will produce a dropdown with the value containing (dose_)id, and the text you see as the value of $displayField(usually name/title).
To do this; if I understand you, you would need to first query doses for all the values and store the result in an array using the dose value as the key AND the value, rather than the id as you normally would. You would then be able to access the actual dose value from $this->data.
$doseArray=array();
$doses = $this->Dose->find('all');
foreach($doses['Dose'] as $k => $v) {
$doseArray[$v] = $v;
}
perhaps. Seems a bit redundant so I might be off.
I have this in my table model called Table
$test = $this->find('first', array(
'conditions' => array('table.test_id is NULL'),
'order'=> array('table.created ASC'),
)
);
it doesnt work. Tryingt to get the latest row with some criteria
Well, first of all, to get the latest row, you would want to organize by the created field descending, rather than ascending. Also, there are some problems with your syntax, that I have cleaned up below.
$this->find('first', array('conditions'=>array('Table.test_id'=>NULL), 'order'=>array('Table.created'=>'desc')));
I am trying to 'tag' multiple 'points' with multiple tags. I'm tagging my single points successfully. Unfortunately, when i try and use a tag, such as 'test2' on another point as a tag it is either giving me a duplicate entry error if i have my 'unique' set to false or if 'unique' is set to true, it will del my tag for all other points for 'test2' and create a single new one.
Here is what i have for my post data:
Array
(
[Tag] => Array
(
[id] => 4b7af6d7-787c-4f10-aa49-2502c0a80001
[name] => Test2
)
[Point] => Array
(
[id] => 4b47c66f-a130-4d12-8ccd-60824051e4b0
)
)
In my tag model i have this:
public $hasAndBelongsToMany = array(
'Point' => array(
'className' => 'Point',
'joinTable' => 'points_tags',
'foreignKey' => 'tag_id',
'associationForeignKey' => 'point_id',
'unique' => false)
);
I have tried this with 'unique' set as true, too. Unfortunately, this will delete any other instances of 'Test2' in the join table ('points_tags').
I have tried this using both save() and saveAll(). Both are giving me this error:
Warning (512): SQL Error: 1062: Duplicate entry '4b7af6d7-787c-4f10-aa49-2502c0a80001-4b47c66f-a130-4d12-8ccd-608' for key 'MAN_ADD' [CORE/cake/libs/model/datasources/dbo_source.php, line 527]
Query: INSERT INTO points_tags (tag_id,point_id,id) VALUES ('4b7af6d7-787c-4f10-aa49-2502c0a80001','4b47c66f-a130-4d12-8ccd-60824051e4b0','4b7b39f3-46f8-4744-ac53-3973c0a80001')
Thoughts????
Suggestions????
Where does the id come from? I'm guessing its a primary key of the table, and from what I understand from your post (please write more clearly, help us help you) the problem isn't with points or tags, but with the id in the points_tags table.
When you use the save method, are you doing it inside of a loop? Remember, best practice is to call model::create() whenever you're saving in a loop.
I frequently find that when I have issues with the HABTM saving behavior, it's because I didn't call model::create.
