I developed an invoice template designer as part of a project which can be used to design invoice templates. Once the invoice template is created its html is saved to the database ready to be used.
Now a user can create an invoice using the template but that is where my problem comes in. My invoice template is created with place holders and its a table. please check screenshot
How can I replace the table cell values since it was created dynamically and there is no way I can access the table cells with a PHP loop. I really need ideas with possibly an example. This is my code:
if (!empty($_GET['invoice_id']) && $_GET['invoice_id']) {
$invoice_id = $_GET['invoice_id'];
$invoiceValues = getInvoice($invoice_id);
$invoiceItems = getInvoiceItems($invoice_id);
}
$invoiceDate = date("d/M/Y, H:i:s", strtotime($invoiceValues['order_date']));
$template_name = getinvoicetemplatename();
$template = get_template($template_name[0]);
//replace template var with value
$token = array(
'[Business_Name]' => 'http://www.codexworld.com',
'[Business_Address_1]' => 'CodexWorld',
'[City]' => $userName,
'[State]'=> $userEmail,
'[Postal_Code]' => 'http://www.codexworld.com',
'[Business_Phone_Number]' => 'CodexWorld',
'[Business_Email_Address]' => $userName,
'[Client_Name]'=> $userEmail,
'[Client_Address_line_1]' => 'http://www.codexworld.com',
'[Invoice_Number]' => 'CodexWorld',
'[Date]' => $invoiceDate
);
foreach ($token as $key => $value){
$output = str_replace($key, $value, $template[0]);
}
$i = 0;
foreach ($invoiceItems as $invoiceItem) {
$i++;
$output = str_replace("[course_no_{$i}]", $invoiceItem["item_code"], $output);
$output = str_replace("[product_{$i}]", $invoiceItem["item_name"], $output);
$output = str_replace("[delegates_no_{$i}]", $invoiceItem["order_item_quantity"], $output);
$output = str_replace("[price_{$i}]", $invoiceItem["order_item_price"], $output);
$output = str_replace("[total_{$i}]", $invoiceItem["order_item_final_amount"], $output);
}
