I have a list of item and retrieving it in PHP array:
array(
'Daging Kambing Beku 2' => array(
(int) 4 => '80.00',
),
'Daging Rusa' => array(
(int) 32 => '4000.00'
),
'Sayur Kangkung' => array(
(int) 31 => '5000.00'
),
'Sayur Sawi' => array(
(int) 30 => '600.00',
(int) 29 => '4.00'
),
'Sayur Lemau' => array(
(int) 28 => '1.00'
),
'Sayur Sayuranj' => array(
(int) 27 => '1.00'
),
'Sayur Segar ke?' => array(
(int) 26 => '5.00'
),
'French Fries' => array(
(int) 25 => '90.00'
),
'Daging Arnab' => array(
(int) 33 => '5.00'
),
'Daging Kerbaul' => array(
(int) 34 => '20.00'
)
)
Array explain :
'Daging Kambing Beku 2' => array(
(int) 4 => '80.00',
),
'Daging Kambing Beku 2' is the name of item.
(int) 4 is the ID for the items table.
'80.00' is the price .
My problem is,I want to make a function add new Item each time Customer make an order.
I'd try using jquery read the PHP array and to add a list of item when Customer clicking "Add New Item" but it's failed.
I want to do something like this:
https://demo.phppointofsale.com/index.php/sales
Customer can add many Items without submitting page frequently.
I'm using CakePHP for my development.
I'll appreciate any kind of help. thanks.
Just a reminder, to use php array in js, you need to do some convertion like :
<script>
<?php echo "var js_array = ".json_encode($php_array).';'?>
</script>

i have a datatable for which my jquery is as follows,
$('#example').DataTable({
"lengthMenu": [[10,15,20,25,-1], [10,15,20,25,'All']],
"processing": true,
"serverSide": true,
ajax: {
url: 'url2',
dataSrc: 'data'
},
columns: [
{ data: 'column1' },
{ data: 'column2' },
{ data: 'column3' },
{ data: 'column4' },
{ data: 'column5' },
{ data: 'column6' }
]
});
this is working properly. The only issue is although its showing pagination links, they are not clickable and all the rows are displayed in first page itself.
for eg. if there are 100 rows, the links are getting generated 1-10 but all the 100 records are showing on the first page itself.
I've referred ,
https://datatables.net/examples/data_sources/server_side
what am i doing wrong here?
Thank you for your suggestions
Server side code -
$total_records = $this->model2->getTotal();
$query['results'] = $this->model1->get_Data();
$data = array('data' => $query['results'],
"draw" => (isset($_REQUEST["draw"]) ? $_REQUEST["draw"] : 0),
"recordsTotal" => $total_records,
"recordsFiltered" => $total_records
);
echo json_encode($data);
I think i know what am i doing wrong,
when i print $_GET in my php code it comes out to be empty. But it is supposed to have the limit and offset value.
How to i send limit offset in $_GET?
You need to know how many records go on a page, and how many records there are.
Your SQL will end in OFFSET 30 LIMIT 10 (for example).
First get total Records. Page will come through your URL and default to page 1 if not set.
The offset is calculated like this (example, page 3):
$totalPages = ceil($totalRecords / $numPerPage); // round up the way.
$offset = ($page * $numPerPage) - $numPerPage; // (3 * 10 = 30) - 10 = offset 20
Your SQL will therefore grab records with OFFSET 20 LIMIT 10
This is what your server.php should looks like. Think you are missing some lines of code:
<?php
$table = 'employees';
$primaryKey = 'id'; // Table's primary key
$columns = array(
array( 'db' => 'id', 'dt' => 0 ),
array( 'db' => 'first_name', 'dt' => 1 ),
array( 'db' => 'last_name', 'dt' => 2 ),
array( 'db' => 'position', 'dt' => 3 ),
array( 'db' => 'date', 'dt' => 4 ),
array( 'db' => 'updated', 'dt' => 5 ),
);
$sql_details = array(
'user' => 'username',
'pass' => 'password',
'db' => 'database',
'host' => 'localhost'
);
require( 'ssp.class.php' );
echo json_encode(
SSP::simple( $_POST, $sql_details, $table, $primaryKey, $columns )
);
?>
End result: https://databasetable-net.000webhostapp.com/
This should get you in the right direction. Think the ssp.class.php file might need added too, unsure if you have it (you can find it on github). Hope this helps!
I use server side processing files from the download as starting point with the ssp.class.php file. All works fine, but not the button. In the last column, I want to add some buttons. A lot to be found about this, but not working for me because I defined column data in php and not js. I can't put a function inside the column array like in the js examples.
I have the following code running:
<script type="text/javascript">
$(document).ready(function() {
pageSetUp();
var table = $('#dt_basic').dataTable({
"processing": true,
"serverSide": true,
"ajax": "index.php?loc=client/clients"
});
});
</script>
PHP
<?php
public function clients() {
$columns = array(
array( 'db' => 'id', 'dt' => 0 ),
array( 'db' => 'name', 'dt' => 1 ),
array( 'db' => 'address', 'dt' => 2 ),
array( 'db' => 'telephone', 'dt' => 3 ),
);
$table = 'clients';
$primaryKey = 'id';
$sql_details = array(
'user' => #####,
'pass' => #####,
'db' => #####,
'host' => #####
);
echo json_encode(
SSP::simple( $_GET, $sql_details, $table, $primaryKey, $columns )
);
}
?>
I want to add 21 checkboxes and a text field(Name) in a good design way. Also there must be "check all button" to check all the checkboxes, how to do it in module PHP page in prestashop.
Since I am new to prestashop I don't know about the form submission, I have to save these two fields together as a json array in database.
Is that possible in prestashop? please help me regarding this.
prestashop version = 1.6
Thanks in advance
Sample code
protected function getConfigForm()
{
return array(
'form' => array(
'legend' => array(
'title' => $this->l( 'Generate Export Order Settings' ),
'icon' => 'icon-cogs'
),
'input' => array(
array(
'type' => 'checkbox',
'name' => 'display',
'values' => array(
'query' => array(
array(
'id' => 'all_fields',
'name' => $this->l('All Fields'),
'val' => '1'
),
),
'id' => 'id',
'name' => 'name'
)
),
),
'submit' => array(
'title' => $this->l( 'Save Export Settings' ),
'class' => 'button pull-right',
'name' => 'save-main-display-settings',
)
),
);
}
I don't know how to add check box in 3 columns and 7 rows and select all button to select all the checkbox.
You can use the following JS code to add check all functionality:
$('.chk_boxes').click(function(){
var chk = $(this).attr('checked')?true:false;
$('.chk_boxes1').attr('checked',chk);
});

I have pasted this code in my main function.php and it works great
but I want to add an image to my woocommerce product and I do not know how I can achieve that. Does anyone have an idea for doing it?
function woo_add_custom_general_fields() {
global $woocommerce, $post;
woocommerce_wp_text_input(
array(
'id' => 'telnr',
'label' => __( 'Nr. Tel)', 'woocommerce' ),
'placeholder' => 'Nr',
'desc_tip' => 'true',
'description' => __( 'tel nr.', 'woocommerce' )
)
);
}
function woo_add_custom_general_fields_save( $post_id ){
$woocommerce_telnr = $_POST['telnr'];
if( !empty( $woocommerce_telnr ) )
update_post_meta( $post_id, 'telnr', esc_html( $woocommerce_telnr ) );
}
This is what I tried and which fails:
function woo_options_add($options) {
// This is a option heading
$woo_metaboxes = array(
"image" => array (
"name" => "image",
"label" => "Post Image",
"type" => "upload",
"desc" => "Upload file here…"
)),
// Return new options
return $options;
}
I have data in Drop down list as per role(for every role table are different).
I don't have any idea how to do because I am not familiar with yii2 First select a role and after selecting role I want data from different different table as per role
<?= $form->field($model, 'role')->dropDownList( [ 'A' => 'Admin', 'M' => 'Member', 'P' => 'Practice', ],['prompt'=>'--Select a Role--',]);?>
<?= $form->field($model, 'code')->dropDownList(
ArrayHelper::map(Member::find()->all(), 'id', 'memberCode'),
['id'=>'memberCode']
);
?>
You Need to update your 2nd dropdown when you select any value from dropdown 1st. Lets say 2nd drop down have id #dropdown2 so, i dit in yii you can change it according to yii2.
echo $form->dropDownListGroup(
$model, 'id', array(
'wrapperHtmlOptions' => array(),
'widgetOptions' => array(
'data' => CSystemGenerated::getProjectName($model->c_id),
'htmlOptions' => array(
'prompt' => 'Select Project',
'ajax' => array(
'type' => 'POST',
'url' => your url,
'update' => '#dropdown2',
//'dataType' => 'json',
'data'=>array('id'=>'js:this.value'),
)
),
),
)
);
<?php
echo $form->dropDownListGroup(
$model, 'tag', array(
'wrapperHtmlOptions' => array(),
'widgetOptions' => array(
'data' =>$this->getTags(),
'htmlOptions' => array(
'prompt' => 'Select Tags',
),
)
)
);
?>
