Call php function when click a button - php

Question

I have a code :
<?php
getPriceListHeader();
function getPriceListDetail($PriceListCode)
{
$resource = Mage::getSingleton('core/resource');
$readConnection = $resource->getConnection('core_read');
$query = "SELECT * FROM pricelisdetail where pricelist_code='".$PriceListCode."'";
$results = $readConnection->fetchAll($query);
echo "<table id='tbdata'>
<thead>
<tr>
<th>Price List Code</th>
<th>Price List Name</th>
<th>Effective From</th>
<th>Effective To</th>
</tr>
</thead>
<tbody> ";
foreach ($results as $row)
{
echo "<tr>";
echo "<td> ".$row[entity_id];
echo "<td> ".$row[sku];
echo "<td> ".$row[sku];
echo "<td> ".$row[sku];
};
echo " </tbody>
</table> ";
}
function getPriceListHeader()
{
$resource = Mage::getSingleton('core/resource');
$readConnection = $resource->getConnection('core_read');
$query = 'SELECT * FROM pricelistheader';
$results = $readConnection->fetchAll($query);
echo "
<h2>Price List</h2>
<div>
<h3>Please select Price List</h3>
<div>
<select class='element select large' id='pricelist' name='element_2'>";
foreach ($results as $row)
{
echo '<option value="' . $row[entity_id]. '">' . $row[sku] . '</option>';
}
echo "</select>
</div>
<input type='button' class='button' name='insert' value='Get Data' onclick='getPriceListDetail(pricelist.value)'/>
";
getPriceListDetail('');
}
?>
I have a dropdown list, a button, a table
When I select a value from dropdown list, then I click button , table will be filled data again. There are 2 method, getPriceListHeader(): load data header when load the page, getPriceListDetail : load data detail when click a button. I try to put event getPriceListDetail(value) to button, but when I click, nothing happens
Please help me how to do this.

Answer 1

Yes, you can call php via ajax request to server like this (very simple):
Note that the following code uses jQuery
jQuery.ajax({
type: "POST",
url: 'my_php_function.php',
dataType: 'name_the_data_type',
success: function (data) {
// here you will get the response your function
}
});
and my_php_function.php like this:
<?php
// here is your php code or function
?>
from the source How can I call PHP functions by JavaScript?

Answer 2

You can't attach PHP function to HTML. PHP is server-side language, so after it's displayed in users browser you can't refer to PHP again, unless you reload page.
There are 3 options I think you can do:
Reload page after changing select page and using GET prepare new data.
Send all data to user browser and than show only part of it related to selected option.
Use AJAX and ask server for new data in background.

Answer 3

Finally, I found out the way.It works for me. Now, I do not understand the code , I am trying to read and get it clearly.
Thanks all for your comments.
$to="";
$from="";
$show_order_statuses = 0;
$orserstatus = "";
$result_order = 0;
//var_dump($results);
//return;
if(!empty($_REQUEST['filter_type']))
{
$orders_row = array();
$filter_type = $_REQUEST['filter_type'];
$resource = Mage::getSingleton('core/resource');
$readConnection = $resource->getConnection('core_read');
$query = " SELECT * FROM pricelistitem where pricelist_code='".$filter_type."' ";
// $query = 'SELECT * FROM pricelistheader1';
$results = $readConnection->fetchAll($query);
foreach ($results as $rowid)
{
$result_order=10;
$orders_row[]=array($rowid['pricelist_code'],$rowid['product_code'],number_format( $rowid['unitprice'],2),$rowid['UOM']);
// $orders_row[]=array(1,1,1,1,1);
}
