I have a table with a lots of data in my live server database. In that case if I load the total data at a time it get 12-15 seconds which is awkward. So I need to load the table server side. I have done it via ssp.class.php . It going fine when I load the table as normal structure like below:
array( 'db' => 'tel1', 'dt' => 0 ),
array(
'db' => 'is_active',
'dt' => 1,
'formatter' => function( $d, $row) {
if($d==0){
$tr_color='no';
}else{
$tr_color='yes';
}
return $tr_color;
}
);
But I need to access a array which is define outside formatter function. I have tried to access it as global variable but it is not available formatter function. Also it is not passed as parameter. So how can I access outside variable inside formatter function:
I have tried like below:
array(
'db' => 'genere',
'dt' => 0,
'formatter' => function( $d, $row, $lang ) {
$gender = '';
if($d=='M'){
$gender = $lang['maschio'];
}else if($d=='F'){
$gender = $lang['femmina'];
}else if($d=='A'){
$gender = $lang['azienda'];
}
return $gender;
}
The above code does not return anything. It returns blank in browser network. $lang is the array of outside array. How can I pass this array inside the formatter function. Sometime it is database connection also. May be I need to fetch some record from another table. SO this time I can not do the operation.
I have tried to fetch Datatable data from ajax as server side loading. But can not access outside array or variable which is defined outside formatter function.

Alright so I have an insert query that I would like to run but the issue I am having is with getting object properties/values that I need to insert.
Say I have a query that looks like the one below.
$this->db->insert('tblitems_in', array(
'platform' => $item['Platform'],
'ram' => $item['RAM'],
'qty' => $item['qty'],
'rate' => number_format($item['rate'], 2, '.', ''),
'rel_id' => $insert_id,
'rel_type' => 'estimate',
'item_order' => $item['order'],
'unit' => $item['unit']
));
This works fine when the person chooses RAM on the webpage which sets the $item Objects property 'RAM' to the value that was picked. Now if they choose HardDrive, that properties name is now sent as 'HardDrive' with the value they chose. Is there a way that i Could replace the 'ram' and 'RAM' from the below example with a variable so I could change what the property name is that I would like to insert and insert into the corresponding db column?
EDIT:
I should have added that the options on the webpage are also dynamically created from a database so I do not know at the time of coding what the property names are. They could be RAM, HardDrive, Processor, maybe even Elephant. I was hoping I could use variables so that I could look at the DB used to create the webpage so that I know the property names and then dynamically add those names into the query.
EDIT:
Right now I am using the following code in order to get all the possible options that can be received from the webpage from a DB the webpages uses to create itself.
$plat_options = $this->db->get('tblplatform_options')->row()->name;
In the database right now it is only populated with names RAM and HardDrive to make things known for testing purposes. So this returns $plat_options = {RAM, HardDrive}. I now have to figure out how to test is $item has these(RAM and HardDrive) as properties and if $item does have them then add them into the query previously shown.
You can set an array of key => variable names, then loop over those values to see if they exist in the $item variable and, if so, add that value to the data to be inserted into the db:
//default array of data to insert
$data = [
'platform' => $item['Platform'],
'qty' => $item['qty'],
'rate' => number_format($item['rate'], 2, '.', ''),
'rel_id' => $insert_id,
'rel_type' => 'estimate',
'item_order' => $item['order'],
'unit' => $item['unit']
];
//Get column names from db
$plat_options = $this->db->get('tblplatform_options')->row()->name;
// $plat_options = [RAM, HardDrive]
//Check if $item[$name] exists. If it does, add that to the
// array of data to be inserted
foreach($plat_options as $key) {
if(array_key_exists($key, $item)) {
$data[$key] = $item[$key];
}
}
$this->db->insert('tblitems_in', $data);

I'm not sure this will work (I don't understand the use case).
It is possible, using array_diff_key to get a list of array keys that exist in $item but not in $data. With this array of keys, you can add the missing keys.
I have altered my previous code to demonstrate this.
You could create the array one element at a time based on whatever field data you received. I used a switch statement, but it could be a simple if/then/else as well.
$data_array = array();
$data_array['platform'] = $item['Platform']
switch($item['Object'] {
case 'HardDrive':
$data_array['harddrive'] = $item['HardDrive'];
break;
case 'RAM':
$data_array['ram'] = $item['RAM'];
break;
}
$data_array['qty'] = $item['qty'];
$data_array['rate' = number_format($item['rate'], 2, '.', '');
$data_array['rel_id'] = $insert_id;
$data_array['rel_type' = 'estimate';
$data_array['item_order'] = $item['order'];
$data_array['unit'] = $item['unit'];
$this->db->insert('tblitems_in', $data_array);
I'm having an issue using the Quickbase API to perform the following:
SELECT 1, 2, 3 FROM table AA that has column BB = 1
foreach record {
Insert 1, 2, 3 into table ZZ.
}
function add_children($opportunity_id) {
global $config;
$qbc = new QuickBase($_SESSION['qb_username'] ,
$_SESSION['qb_password'],
true,
$config['AA'],
$config['debug'],
$config['app_token']);
$xml = $qbc->do_query("{'" . $config['AA'] . "'.EX.''}", 0, 0, 'a', 0, '', '');
$records = array();
foreach($xml->record as $record) {
$r = array();
$r['record_id'] = $record->record_id_;
$r['account_number'] = $record->account_number;
$records[] = $r;
$xml = $qbc->add_record($records[]);
}
}
First, I'm assuming that you're using this PHP SDK by QuickbaseAdmirer https://github.com/QuickbaseAdmirer/QuickBase-PHP-SDK. There are a few potential problems with your code.
Double check that your constructor is correct. Unless you've modified it, the Quickbase constructor in the SDK (again that I'm assuming you're using) takes user name, password, xml, database id, and then token in that order. Whatever value is in $config['debug'] may be taken as the token and the value of $config['app_token'] may be taken as your realm. Also, $config['AA'] as used in the constructor should be a string of random seeming characters like "bbqn1y5qv". Here's the constructor in the SDK for reference:
public function __construct($un, $pw, $usexml = true, $db = '', $token
= '', $realm = '', $hours = '')
Your query $xml = $qbc->do_query("{'" . $config['AA'] . "'.EX.''}", 0, 0, 'a', 0, '', ''); is not returning any records because $config['AA'] is both being used as your DBID (in the constructor) and your field ID in the query. The DBID must be a string and the field ID must be an integer that corresponds to the field you're making the query for. For example, if you wanted to return records created today your query would be '{1.IR.today}' because 1 is always the field ID for date created. It's also not returning any records because the SDK requires queries be passed as an array of arrays. So, my records created today query needs to be rewritten as:
$query= array(
array(
'fid' => '1',
'ev' => 'IR'),
'cri' => 'today'),
);
You'll also need to pass a string of period separated values to the clist parameter of the method or leave it blank for the table defaults. For example, if I wanted to get the date created and record ID for all records in this table sorted by date ascending, I would use this:
$query= array(
array(
'fid' => '3',
'ev' => 'GT'),
'cri' => '0'),
);
$xml = $qbc->do_query($query, '', '', '1.3', '1', '', 'sortorder-A');
You can read up more on the Quickbase API, and do_query specifically, here http://www.quickbase.com/api-guide/index.html#do_query.html
The add record API call takes pairs of field IDs and values. The SDK handles that by taking an array of arrays with 'fid' and 'value' pairs. Assuming you want to put the value of $record->record_id_ in field #37 and $record->account_number in field #30 your code should look like this:
foreach($xml->record as $record) {
$records= array(
array(
'fid' => '37', //Whatever field you want to store the value to
'value' => $record->record_id_),
array(
'fid' => '30',
'value' => $record->account_number),
);
$xml = $qbc->add_record($records);
}
Throw in a print_r($xml); at the end and you can see any response from Quickbase for debugging. You should get something like this for a success:
SimpleXMLElement Object ( [action] => API_AddRecord [errcode] => 0 [errtext] => No error [rid] => 81 [update_id] => 1436476140453 )
The way your code is presented, you may not get the results you expect. Your do query and add record method calls are performed on the same table and that isn't normally what someone would want. Usually, the goal is to perform a do query on one table and then use that data to add records in a different table. If that's the case, you'll need to change the database ID in your $qbc object before you preform the add record call. This is easy enough to do with $qbc->set_database_table('DBID'); where DBID is the target table ID (which should be a string of random seeming characters like "bbqn1y5qv").
Best of luck!
I have some code that should be deleting a record from an embedded MongoDB document.
Here is the code:
public function actionDeleteSaved()
{
$savedLink = $_POST['savedLink'];
$userId = Yii::app()->user->getId();
$current = SaveLink::model()->findByPk($userId);
if(in_array($savedLink, $current->links))
{
array_slice($current->links, $savedLink);
$current->save();
}
}
This is what is passing the data to the controllers action method:
echo CHtml::ajaxButton(
'delete',
Yii::app()->createUrl("dashboard/index/deletesaved"),
array( // ajax options
'type' => 'POST',
'context' => "js:this",
'data' => array(
'savedLink' => $savedLink
)
),
array( //html options
'class'=>'deleteSaved'
)
);
This is what renderPartial looks like:
$this->renderPartial('_deleteSaved', array('savedLink'=>$s));
What I want being posted is being posted correctly but I'm not sure if it's communicating with the Controller and passing the data through or if my code for removing the data from the database is correct.
Any help would be greatly appreciated, thanks.
The problem is with array_slice part. As specified in php docs array slice does not modify array parameter.
Use array_splice instead (it modifies passed array param) and array_search to get key:
if(in_array($savedLink, $current->links))
{
$key = array_search($savedLink, $current->links);
array_splice($current->links, $key, 0);
$current->save();
}
NOTE: If $current->links is embedded documents (objects) array, you might have to find $key and check if is in array some other way.
I'm able to query my dynamodb tables, but I only want to retrieve the actual value. I don't want the formatting output. This same question has been answered here for Java, but I'm looking for the PHP solution:
Retrieving just the item value from a dynamodb table?
Here is my getitem query:
$response = $dynamodb->getItem(array(
"TableName" => $tableName,
"ConsistentRead" => true,
"Key" => array(
"userguid" => array(Type::STRING => $userguid)
),
"AttributesToGet" => array("token")
));
print_r($response["Item"]["token"]);
Here is the output:
Array
(
[S] => 9d194513
)
All I want to get back is:
9d194513
I assumed the logical answer would be to change the last line to:
print_r($response["Item"]["token"]["S"]);
But then my code doesn't return anything at all. Obviously still learning PHP here, and any help would be appreciated.
Don't use print_r function, just either echo your variables
echo $response["Item"]["token"]["S"];
or store in a variable for later use
$res_token = $response["Item"]["token"]["S"];
You can also use the getPath convenience method built into the Model object that the SDK returns for operations.
echo $response->getPath('Item/token/S');
For more information about working with responses in the SDK, see the Response Models page in the AWS SDK for PHP User Guide.
Though it's an old question but for anyone coming to this page for seeking answer, this is how I have done it.
getItem returns a Resultobject. You can call the get() function of the SDK, which will give you an array containing the exact value.
$params = [
"TableName" => "EpgApiAccessCount",
"Key" => $this->marshalJson('
{
"ApiUserKey": "' . $apiUserkey . '"
}
')
];
$result = $this->client->getitem($params);
if (!$result instanceof ResultInterface) {
return 0;
}
$item = $this->unmarshalItem($result->get("Item"));
return $item["AccessCount"];
Of course your value and table name will be different, and you can print or do anything else with the value.
I have a function in my Teacher model which returns categories array.
getCaterogies() {
return array('1' => 'short tempered', '2' => 'funny', '3' => 'visionary', ...);
}
I am storing indexes in database and displaying values everywhere using the value of the array corresponding to that..
$categories = $teacher->categories;
$category = $categories[$teacher->category];
I am doing this because once somebody suggested to me not to store strings in a database which are statuses, instead store integer values, and either store the conversion in the database or define it in ht model. The problem with strings is that they are more prone to human errors in comparisons. Maybe because of case sensitiveness.
Now the problem I am facing is that while displaying values in gridview, I need to write the 2 lines in a value field, but it is an expression, and outside variables also it doesn't take.
How can I get this working for gridview?
You can use anonymous function as value which can take $row, $data params where $row holds the row number (zero-based) and $data contains the data model for the row.
That way you can have it defined inside only.
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$dataProvider,
'columns'=>array(
array(
'name'=>'..',
'value'=>function($data,$row){
$categories = $teacher->categories;
return $categories[$data->category];
},
),
),
));
And if you want to use it from outside, you can rely on PHP's use:
$categories = $teacher->categories;
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$dataProvider,
'columns'=>array(
array(
'name'=>'..',
'value'=>function($data,$row) use ($categories){
return $categories[$data->category];
},
),
),
));
I would personally recommend second one, because that way the calculation of the array will be only once and will be used in all cases.
You can write
$categories = $teacher->categories;
$category = $categories[$teacher->category];
in one line:
$category = $teacher->categories[$teacher->category];
Also, I suggest you to use another solution:
class ModelClass
{
const STATUS_SHORT_TEMPERED = 1;
const STATUS_FUNNY = 2;
const STATUS_VISIONARY = 3;
}
This allow you to use a more semantic
ModelClass::STATUS_FUNNY;
instead of less semantic
2;
Also, you can compose your array in this way:
getCaterogies() {
return array(
ModelClass::STATUS_FUNNY => 'status funny',
...
);
}
'urlCreator' => function ($action, $model, $key, $index) use($under_category) {
