i cant modify it, because im not the hoster

All i want to change the variable and submit the form automatically

i cant modify it, because im not the hoster

then what can you modify?

[sharmahemal]

u cant modify it. because u use not a local server but use
web server

[Dormilich]

If I had the appropriate rights on a web server, I could modify those’s files to my liking.

Well, this form in a website and i want to change the hidden variable in that form then submit it using a PHP page
I want that to be done with one single step like "url or simple script" because it will be part of automated script.

Any ideas ??

*Sorry for late response

[sharmahemal]

u will use ajax for that because ajax is mostly use for that

[mostafaz4]

could you help me doing this script using AJAX ??

That form is in the PHP file, if you can't change the PHP file, then you can't change the form.

[mostafaz4]

NOOOOOO, I won't change the source ...
I just want to do some steps automatically without humanitarian intervention

Something like "Marco", I click one link on a php file i host
and it do the rest for me.

The rest is:
1. Navigate to another website [i don't host]
2. Submit a form [with method post] and i couldn't change it because i don't host it

This script would be a part of automated script

Hope i describe it well.

write the form code as you want it and submit it to the desired address. where the code came from does not matter to the receiving PHP script.

example

// foreign website (example.org) offers following form
<form action="index.php" method="post">
<input type="hidden" name="hvalue" value="123">
</form>

// I can rewrite that locally to
<form action="http://example.org/index.php" method="post">
<input type="hidden" name="hvalue" value="abc">
<input type="hidden" name="vvalue" value="567">
</form>
// and submit it
// whether the result will differ, is another problem

Yeah great work, it works but i could't submit it automatically
This script require me to click on a button to submit the form

I want to submit it automatically, without humanitarian intervention
Like you enter "http://website.com" and it redirects you to "http://anotherwebsite. com" but with the form submitted

OR Could i get the source code of the submitted form from the original website also without humanitarian intervention?

*Thanks for your interest
*Sorry for annoying
