php curl download files that have checkboxes

Question

I want to download these files that have checkboxes http://www.pse.com.ph/stockMarket/marketInfo-marketActivity.html?tab=4 but I don't know what to add in my code.

<?php

$dlurl = 'http://www.pse.com.ph/stockMarket/marketInfo-marketActivity.html?tab=4';

$saveTo = 'C:\Users\Test\Desktop\phpfiles\datena.pdf';

$fp = fopen($saveTo, 'w+');

if($fp == false){
    throw new Exception('Could not open:' .$saveTo);
}

$ch = curl_init($dlurl);

curl_setopt($ch, CURLOPT_FILE, $fp);

curl_exec($ch);

?>

Answer 1

That page it's really a form. When you press the download button it sends the form within GET method changing the browser to a new url like this:

http://www.pse.com.ph/stockMarket/marketInfo-marketActivity-marketReports.html?ajax=true&method=downloadMarketReports&ids=[%22PSE_DQTRT20173306%22]

The ids parameter, contains one or more ids of the documents. If you select only one checkbox the PDF it's downloaded directly, if you select more than one the server provides you a zip with all the documents selected.

In your code you should change the url to the desired one.

I think you want to download all the documents. Isn't it ?

1. You should download first within curl the webpage.

2. After that you need to parse the webpage with regular expressions looking for the IDS of each document. PHP Parse HTML code

3. And when you have they do a new cURL (like the used on 1) with the download url and the desired Ids like which I posted you before.
