I have a sql command like the following:
DB::table('tb_angsuran_lainlain')->insert(array(
array('id_kegiatan'=>'1','id_siswa'=>'26338','id_bulan'=>'1','nominal'=>'300000'),
array('id_kegiatan'=>'2','id_siswa'=>'26338','id_bulan'=>'1','nominal'=>'300000'),
array('id_kegiatan'=>'','id_siswa'=>'','id_bulan'=>'','nominal'=>''),
));
I want when the value is empty, it does not fill in the value in the table
array('id_kegiatan'=>'','id_siswa'=>'','id_bulan'=>'','nominal'=>''),
How to master ?
If I understood your question correctly, you only want to create a row for records that has some of their values filled.
To achieve that, use array_filter to get only those record that have some values:
$records = [
['some' => '1', 'key' => '2'],
['some' => '3', 'key' => '4'],
['some' => '', 'key' => ''],
];
$records = array_filter($records, function ($record) {
return count(array_filter($record));
});
DB::table('table_name')->insert($records);

I have a comparative set of arguments for WP_Query involving a custom field.
On a page I need to say "Are there going to be results?, if so display a link to another page that displays these results, if not ignore" There are between 500 and 1200 posts of this type but could be more in the future. Is there a more efficient or direct way of returning a yes/no to this query?
$args = array(
'post_type' => 'product',
'posts_per_page' => -1,
'meta_query' => array(
array(
'key' => 'partner',
'value' => $partner,
'compare' => 'LIKE',
),
),
);
$partner_query = new WP_Query($args);
if ($partner_query->have_posts() ) { [MAKE LINK] }
The link is not made from data returned, we already have that information.
Perhaps directly in the database. My SQL is not up to phrasing the query which in English is SELECT * from wp_posts WHERE post_type = 'product'} AND (JOIN??) post_meta meta_key =
partner AND post_id = a post_id that matches the first part of the query.
And if I did this, would this be more efficient that the WP_Query method?
Use 'posts_per_page' => 1 and add 'no_found_rows' => true and 'fields' => 'ids'. This will return the ID of a matching post, and at the same time avoid the overhead of counting all the matching posts and fetching the entire post contents. Getting just one matching post id is far less work than counting the matching posts. And it's all you need.
Like this:
$args = array(
'post_type' => 'product',
'posts_per_page' => 1,
'no_found_rows' => true,
'fields' => 'ids',
'meta_query' => array(
array(
'key' => 'partner',
'value' => $partner,
'compare' => 'LIKE',
),
),
);
$partner_query = new WP_Query($args);
if ($partner_query->have_posts() ) { [MAKE LINK] }
no_found_rows means "don't count the found rows", not "don't return any found rows". It's only in the code, not the documentation. Sigh.
i want to save id of one table to another table how should i write the model and controller.
For example : I have a database like this
tbl1: (id,content,time,date,category)
tbl2: (id,tbl1_id,category_detail)
$tbl1Data = array(
'id' => '',
'content' => 'Hi, content will be here',
'time' => date("H:i:s"),
'date' => date("Y-m-d"),
'category' => 'Electronics'
);
$this->db->insert('tbl1',$postData);
$recordId $this->db->insert_id();
$tbl2Data = array(
'id' => '',
'tbl1_id' => $recordId,
'category_detail' => "alskjdflkajsdlk falsjdflka lsdkfj as",
);
$this->db->insert('tbl1',$postData);
I want Sum of a custom column value in footer
GridView Code
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'booking-grid',
'dataProvider'=>$model->search(),
'columns'=>array(
array(
'name'=>'name',
'header'=>'User Name',
'value'=>'$data->booking_id',
'filter'=>false,
'footer'=>'Total',
'footerHtmlOptions'=>array('class'=>'grid-footer'),
),
array(
'name'=>'id',
'header'=>'User Fee',
'value'=> array($model,'GetUserFee'),
'filter'=>false,
'footer'=>'' . $model->getTotal($model->search()->getData(), 'id'),
'footerHtmlOptions'=>array('class'=>'grid-footer'),
),
),
));
Get Total
public function getTotal($records,$colName){
$total = 0.0;
if(count($records) > 0){
foreach ($records as $record) {
$total += $record->$colName;
}
}
return number_format($total,2);
}
Second column value are calculate user fee.
In footer sum of User Fee values get the wrong sum. It gives the sum of user ids. and id is table column name.
How can I get the sum of User fee column values
Instead of using a literal representation of id, try using the $data variable created by CGridView, which actually IS the current record from the $model currently being processed in each CGridView iteration.
Your code would then be:
array(
'name'=>'id',
'header' => 'User Fee',
'type' => 'raw',
'value' => '$data->id',
'filter' => false,
'footer' => '$model->getTotal($data)',
'footerHtmlOptions' => array('class'=>'grid-footer'),
),
Notice the value of the type attribute is set to raw.
You can even use a PHP function and pass it the $data variable, like so:
array(
'name'=>'id',
'header' => 'User Fee',
'type' => 'raw',
'value' => function ($data) { ... handle $data how you like ... }
'filter' => false,
'footer' => '$model->getTotal($data)',
'footerHtmlOptions' => array('class'=>'grid-footer'),
),

Its a parent child relation,
In childGroup1, getting error during accessing 'PARENT_ID' attribute.
The given error is Trying to get property of non-object.
I am having access dynamically.
How to get PARENT_ID in such case.
return array(
'group1'=>array(
'ID' => 1,
'NAME' => 'Test',
'STATUS' => 1,
),
'childGroup1'=>array(
'ID' => 2,
'PARENT_ID' => $this->getRecord('groups','group1')->ID,
'NAME' => 'Child Test group1',
'STATUS' => 1,
),
);
Since the records are not loaded yet, you cannot use $this->getRecord() to acquire a record. As such, just use plain old array logic to get the record's ID.
$records = array();
$records['group1'] = array(
'ID' => 1,
'NAME' => 'Test',
'STATUS' => 1,
);
$records['childGroup1'] = array(
'ID' => 2,
'PARENT_ID' => $records['group1']['ID'],
'NAME' => 'Child Test group1',
'STATUS' => 1,
);
return $records;
If you need records from other fixtures, just require them.
$groups = require __DIR__.'/group.php';
This, of course, would be what you put at the top of files OTHER than groups.php, in order to gain access to the groups models.
Is there a way to change the default functionality in Zend_Db fetchall() method, so that it doesn't return this:
[0] => 100000055944231
[1] => 100000089064543
[2] => 100000145893011
[3] => 100000160760965
but this:
[100000055944231]
[100000089064543]
[100000145893011]
[100000160760965]
Although your question is actually flawed (noted by BartekR), I suppose you're trying to receive a simple array, instead of a multidimensional one.
You could do:
$results = $this->db->fetchAll($select);
$values = array_map(function($row) { return $row['column']; }, $results);
This will turn:
array(
array('column' => 'test'),
array('column' => 'test2'),
array('column' => 'test3'),
);
into
array(
'test',
'test2',
'test3'
);
(note; my example only works in PHP5.3+, if you're working with PHP5.2, you can define the function and use it by its name with array_map (e.g. array_map('methodName', $results))
I'm looking for a similar solution, I'm trying to load a field returned by the fetchAll($select) as the array key.. Without looping through the entire resultset.
So:
$results = $this->db->fetchAll($select, <FIELDNAME_TO_MAKE_KEY_OF_RESULTS_ARRAY>);
results[<my fieldname>]->dbfield2;
Further to Pieter's, I'd add the case where the rows are themselves arrays, and not just scalars; it's possible to nest the results, to as many fields as the query contains.
e.g. Here with two levels of nesting, respectively on field1 and field2.
$complex_results = array_map(function($row) { return array($row['field1'] => array($row['field2'] => $row)); }, $results);
As always, each row contains all fields, but $complex_results is indexed by field1, then field2 only.
