i use Active record for inserting values to DB.
All other type of queries i do with custom query as it's much easier but the active record insert is quite nice.
So i have this code :
$comment = array (
'point_id' => $object->id,
'title' => $object->title,
'comment' => $object->comment,
'author_name' => $object->author_name,
'is_temp' => 0,
'parent_id' => $object->parent_id
);
return $this->db->insert('comments', $comment);
Now i want to be able to set is_temp as a subquery result, which is :
(SELECT allow_user_comments from subjects where id='somevalue')
How would one achive that?
I was hoping to avoid using third party libraries.
Well, i doubt the fact that that's how you're supposed to do it, but ain't CI all about that?
This is how i got it to work (removing is_temp from the $comment array ofcourse):
$this->db->set($comment);
$this->db->set('is_temp',
'(SELECT allow_user_comments from subjects where id='.$subject_id.')',FALSE);
$this->db->insert('comments');
Feel free to use https://github.com/NTICompass/CodeIgniter-Subqueries. I have used it and it works! Hope it would be useful. :-)

I insert multiple values into my database using saveField function. Here is my code.
$this->Fuel->saveField(
'device_id', $int_fuel_func[0],
'func_code', $int_fuel_func[1],
'device_data', $int_fuel_func[2]
);
It's not a form value. Value automatically insert when the page is refreshed.
It's only inserts first value 'device_id', $int_fuel_func[0],. Other two values are not insert into my database. Any one suggest me how to insert these values.
Thanks in advance
Cake version 2.7.5
You can simply do this as well.
$data = array(
'device_id' => $int_fuel_value[0],
'func_code' => $int_fuel_value[1],
'device_data' => $int_fuel_value[2]
);
$this->Fuel->save($data);
Also try this blog tutorial (cakephp blog tutorial) if you haven't been there before to be more familiar with these things.
My id is not auto Increment it is defined as varchar. Time is not include there also. I got my answer. I use it and it works.
$this->Fuel->set(
array(
'device_id' => $int_fuel_value[0],
'func_code' => $int_fuel_value[1],
'device_data' => $int_fuel_value[2]
)
);
$this->Fuel->save();
saveField function is only for updating one field! use updateAll and pass an array to it :
$this->Fuel->updateAll(
array(
'device_id', $int_fuel_func[0],
'func_code', $int_fuel_func[1],
'device_data', $int_fuel_func[2]
),
array('Fuel.id' => 234) // conditions for the Fuel you want to update
);
Here is my code -
$updatecompany = DB::table('Companies')
->where('ID', (int)$companyid)
->update(array(
'CompanyName' => $companyname,
'CompanyAddress' => $companyaddress,
'CompanyEmail' => $companyemail,
'ContactName' => $contactname,
'CompanyCity' => $companycity,
'CompanyState' => $companystate,
'CompanyZip' => $companyzipcode,
'CompanyPhone' => $companyphone,
));
$updatecompany is always 0. What might be the problem?
One of most possible reasons is that you are updating with the same data in the database.
There needs one out of the box solution, of course if you can do it.
So, no rows are updating, even if the SQL is correct.
Here is my suggestion:
Add a new column updatedOn in DB Table Companies.
The type should be TIMESTAMP and add attribute ON UPDATE CURRENT_TIMESTAMP.
This way you will always get row affected and hence you get return value other than 0.
You don't need to cast $companyId to an integer there. It does not help Laravel's query builder.
Use dd($companyId) and dump the variable before you run the query and find out what it is.
I have a table of values that uses a Where clause to find the row and then updates the values in the row. However it is deleting the value it is searching for after it is already found. So it finds the row using the stockid (not a PK) and updates the row, but leaves the stockid blank afterwards
$data = array(
'towSet' => $towSet,
'transWare' => $transWare,
'oceanFreightBooked' => $oceanFreightBooked,
'BOLrec' => $BOLrec,
'BOLsent' => $BOLsent,
);
$this->db
->where('stockid', $stockHold)
->update('logistics_tracking', $data);
The Strange part is that using this code doing the same thing it works perfectly fine
$data = array(
'recTitle' => $recTitle,
'recPOA' => $recPOA,
'recTitleState' => $recTitleState,
'titleSent' => $titleSent,
);
$this->db
->where('stockid', $stockHold)
->update('title_tracking', $data);
So as a reminder all the other values (towSet, transWare, oceanFreightBooked, ect.. ) all insert and it just blanks out the stockid after updating
Any ideas would be greatly appreciated
Yeah the code was fine, apparently I was just doing too much with one function. Created an external function and passed through an array of the data. Weird.
Thanks for looking!
iam building my web app, and i need to the simplest thing, just update fields inside table with some variables,but its not working he doesnt do anything ,values of the fields remain just as it was.
public function post_eupdate(){
$update = DB::table('app_events')
->where('ev_id', '=', Input::get("id"))
->update(
array(
'ev_op1' => Input::get('op1'),
'ev_op2' => Input::get('op2'),
'ev_coef1' => Input::get('coef1'),
'ev_coef2' => Input::get('coef2'),
'ev_host' => Input::get('host'),
'ev_stime' => Input::get('stime'),
'ev_ns1' => Input::get('ns1'),
'ev_cat' => Input::get('cat'),
'ev_tip' => Input::get('tip'),
'ev_ns2' => Input::get('ns2')
)
);
Your update statements seams good.
My guess would be that the problem is that Input::get("id") isn't a valid id for app_events.ev_id
Try debugging this by replacing ->update with ->get(). If this return null you would know that my assumption is correct. (If not post it in you question.)
As this is the case you have to modify the Input and not this piece of code which makes your question no longer fitting for the problem.
Hello I have been trying to understand how to get data from model by the name of field. I am using cakePHP, and I need to retreive a column's data from a table. The syntax is
> "select name from permissions"
So I tried to find out on book.cakephp.org, so I got the field function, but that only gives me the first value, while I have more than one values for this.
I tried do a
$this->Model->find(array('fields'=>'Model.fieldName'));
but I understood that the syntax itself is flawed.
Can somebody let me know what is the method to query based on column name.
$this->Model->find(array('fields'=>'Model.fieldName'))
You forgot the array function. Also:
$this->Model->find(array('fields'=>array('Model.fieldName')))
will work.
findAllBy will find all records based on the field name.
$this->Model->findAllBy<fieldName>(string $value, array $fields, array $order, int $limit, int $page, int $recursive);
For eaxample:
$this->Permission->findAllByName('Some Name');
http://book.cakephp.org/2.0/en/models/retrieving-your-data.html#findallby
Found it... hope it will help someone.
$workshop_lists = ClassRegistry::init('Workshop')->find('all',array(
'fields'=>array('user_id', 'title')
),
array(
'conditions' => array('user_id' => $this->Auth->user('id')),
'group' => 'Workshop.user_id',
'order' => 'posted DESC',
));
There is no way you can query out based on column name using one of the cake methods. You have to use the query method.
Syntax: $this->Model->('Select columnname from table');
$this->Model->find('all',array('fields'=>array('Model.fieldName')))
it works for me everytime.
If I understood well and you want not only 1 value but the whole values in the column 'name' from the table 'permissions'. In that case you could use:
$this->Model->find('list',$params);
(see explanation for 'find' here)
for the '$params' part you would use:
$params=array('fields'=>array('name'));
or putting all in a single line:
$arrayOfNames= $this->Model->find('list',array('fields'=>array('name')));
This will give you an array '$arrayOfNames' wich key is the 'id' (primary key) in 'permissions' table and wich value is the corresponding name in the field 'name' from the same table. This is the array would be something like:
'id'=>'name'
[23]=>'name1'
[28]=>'name2'
[29]=>'name3'
............
very much like I think you want. Hope it helps.
$this->Model->find('list', ['valueField' => 'fieldName']);
