auto submit form using cron job

Question

My requirement: I need to get data from database and submit the values on some other website form after each 2 min .

I am planning to do this by creating as similar form and populating values from db then submit it using document.getElementById("webform-form").submit();

It works fine if I manually run the url

but it doesn't work when I submit it using cron job.

Cronjob is ignoring this state of form submission. I want to know whether it is possible to do it using cronjob and form submission. If not, please suggest me how should I proceed.

Thanks in advance

show the code of the cronjob? – halkujabra May 24 '14 at 08:31 — halkujabra, May 24 '14 at 08:31

You could use a "headless" browser like PhantomJS to submit the form and then put the PhantomJS script on a cron - which shouldn't be that hard.

You can find a sample form submit for Phantom here and then you could just put it in the cron like this:

*/2 * * * * phantomjs you-form-submit-script.js

Using the method you've described you need your page to be loaded by real browser and to be run by javascript in it.

I think you want to do a POST request directly from your PHP script without being loaded by browser. It can be done by CURL. You can find some examples on this site.

We should keep in mind that you can't submit a form with CURL if you have CSRF in place :) – Bogdan Constantinescu May 24 '14 at 08:42
well, actually you can, but you need to download the page with the form and parse it first:) – Lukas Kral May 24 '14 at 08:53
