Add custom multi language product fields - php

Question

I'm trying to add multi-language custom product fields. Please anybody help me out from this problem.
Add table
CREATE TABLE IF NOT EXISTS `product_custom` (
`product_id` int(11) NOT NULL,
`title` varchar(255) CHARACTER SET utf8 NOT NULL,
` language_id` int(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
In admin/view/template/catalog/product.tpl
<div class="tab-pane" id="tab-custom">
<div class="table-responsive">
<table id="custom" class="table table-striped table-bordered table-hover">
<thead>
<tr>
<td class="text-right">Title</td>
<td class="text-right">Value</td>
<td></td>
</tr>
</thead>
<tbody>
<?php $custom_row = 0; ?>
<?php foreach ($product_customs as $product_custom) { ?>
<tr id="custom-row<?php echo $custom_row; ?>">
<?php foreach ($languages as $language) { ?>
<td class="text-right">
<img src="view/image/flags/<?php echo $language['image']; ?>" title="<?php echo $language['name']; ?>" style="margin-right:10px;padding:5px 0px"/><br/>
<input type="text" name="product_custom[<?php echo $custom_row; ?>][<?php echo $language['language_id']; ?>][title]" value="<?php echo $product_custom[$language['language_id']]['title']; ?>" placeholder="Title" class="form-control" />

Check with following changes :
Add table
CREATE TABLE IF NOT EXISTS `oc_product_custom` (
`opc_id` int(11) NOT NULL AUTO_INCREMENT,
`product_id` int(11) NOT NULL,
PRIMARY KEY (`opc_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
CREATE TABLE IF NOT EXISTS `oc_product_custom_desc` (
`opc_id` int(11) NOT NULL,
`title` varchar(255) NOT NULL,
`language_id` int(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
In admin/view/template/catalog/product_form.tpl
add below html
<div class="tab-pane" id="tab-custom">
<div class="table-responsive">
<table id="custom" class="table table-striped table-bordered table-hover">
<thead>
<tr>
<td class="text-right">Title</td>
<td></td>
</tr>
</thead>
<tbody>
<?php $custom_row = 0; ?>
<?php foreach ($product_customs as $product_custom) { ?>
<tr id="custom-row<?php echo $custom_row; ?>"><td class="text-right">
<?php foreach ($languages as $language) { ?>
<div class="input-group"><span class="input-group-addon"><img src="view/image/flags/<?php echo $language['image']; ?>" title="<?php echo $language['name']; ?>" /></span>
<input type="text" name="product_custom[<?php echo $custom_row; ?>][<?php echo $language['language_id']; ?>][title]" value="<?php echo $product_custom[$language['language_id']]['title']; ?>" placeholder="Title" class="form-control" />
</div>
<?php }?>
</td>
<td class="text-left"><button type="button" onclick="$('#custom-row<?php echo $custom_row; ?>').remove();" data-toggle="tooltip" title="<?php echo $button_remove; ?>" class="btn btn-danger"><i class="fa fa-minus-circle"></i></button></td>
</tr>
<?php $custom_row++; ?>
<?php } ?>
</tbody>
<tfoot>
<tr>
<td colspan="1"></td>
<td class="text-left"><button type="button" onclick="addCustom();" data-toggle="tooltip" title="Add Mediabox" class="btn btn-primary"><i class="fa fa-plus-circle"></i></button></td>
</tr>
</tfoot>
</table>
</div>
</div>
Add below script
<script type="text/javascript"><!--
var custom_row = <?php echo $custom_row; ?>;
function addCustom() {
html = '<tr id="custom-row' + custom_row + '">';
html += '<td class="text-right">';
<?php foreach ($languages as $language) { ?>
html += '<div class="input-group"><span class="input-group-addon"><img src="view/image/flags/<?php echo $language['image']; ?>" title="<?php echo $language['name']; ?>" /></span><input type="text" name="product_custom[' + custom_row + '][<?php echo $language['language_id']; ?>][title]" value="" placeholder="Title" class="form-control" /></div>';
<?php }?>
html += '</td>';
html += ' <td class="text-left"><button type="button" onclick="$(\'#custom-row' + custom_row + '\').remove();" data-toggle="tooltip" title="<?php echo $button_remove; ?>" class="btn btn-danger"><i class="fa fa-minus-circle"></i></button></td>';
html += '</tr>';
$('#custom tbody').append(html);
custom_row++;
}
//--></script>
admin/controller/catalog/product.php
//Custom
if (isset($this->request->post['product_custom'])) {
$product_customs = $this->request->post['product_custom'];
} elseif (isset($this->request->get['product_id'])) {
$product_customs = $this->model_catalog_product->getProductCustoms($this->request->get['product_id']);
} else {
$product_customs = array();
}
$data['product_customs'] = array();
foreach ($product_customs as $key=>$product_custom) {
foreach ($data['languages'] as $language){
$customdata = $this->model_catalog_product->getProductCustom($product_custom['opc_id'],$language['language_id']);
$data['product_customs'][$key][$language['language_id']] = array(
'title' => $customdata['title'],
);
}
}
admin/model/catalog/product.php
in addProduct method add following code before $this->cache->delete('product')
if (isset($data['product_custom'])) {
foreach ($data['product_custom'] as $product_custom_data) {
$this->db->query("INSERT INTO `" . DB_PREFIX . "product_custom` SET `product_id` = '" . (int) $product_id . "'");
$opc_id = $this->db->getLastId();
if (!empty($product_custom_data)) {
foreach ($product_custom_data as $language_id => $product_custom) {
$this->db->query("INSERT INTO `" . DB_PREFIX . "product_custom_desc` SET `opc_id` = '" . (int) $opc_id . "', `title` = '" . $this->db->escape($product_custom['title']) . "', `language_id` = '" . (int) $language_id . "'");
}
}
}
}
In editProduct method add following code before $this->cache->delete('product')
$this->db->query("DELETE FROM " . DB_PREFIX . "product_custom WHERE product_id = '" . (int) $product_id . "'");
$this->db->query("DELETE FROM " . DB_PREFIX . "product_custom_desc WHERE product_id = '" . (int) $product_id . "'");
if (isset($data['product_custom'])) {
foreach ($data['product_custom'] as $product_custom_data) {
$this->db->query("INSERT INTO `" . DB_PREFIX . "product_custom` SET `product_id` = '" . (int) $product_id . "'");
$opc_id = $this->db->getLastId();
if (!empty($product_custom_data)) {
foreach ($product_custom_data as $language_id => $product_custom) {
$this->db->query("INSERT INTO `" . DB_PREFIX . "product_custom_desc` SET `opc_id` = '" . (int) $opc_id . "', `title` = '" . $this->db->escape($product_custom['title']) . "', `language_id` = '" . (int) $language_id . "'");
}
}
}
}
in copyProduct method add following code before $this->addProduct($data);
$data['product_custom'] = $this->getProductCustoms($product_id);
in deleteProduct method add below code before $this->cache->delete('product')
$this->db->query("DELETE FROM " . DB_PREFIX . "product_custom WHERE product_id = '" . (int) $product_id . "'");
$this->db->query("DELETE FROM " . DB_PREFIX . "product_custom_desc WHERE product_id = '" . (int) $product_id . "'");
add below method :
public function getProductCustoms($product_id) {
$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "product_custom WHERE product_id = '" . (int) $product_id . "'");
return $query->rows;
}
public function getProductCustom($opc_id,$language_id) {
$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "product_custom_desc WHERE opc_id = '" . (int) $opc_id . "' AND language_id='".$language_id."' ORDER BY title");
return $query->row;
}
Note : I think there is no need of product_mediabox table.
