Tricky post data

facciazzi

Hello all and thanks in advance for any help.

I'm trying to emulate the behaviour of a Javascript form. I'm using curl to post data but there is one piece of data I don't know how to translate from the originale form:

How can I render this information in a form that can be passed using curl? I tried to manually post the form to a PHP page I created and read the post data with array_keys($_POST). What comes out is:
varname: colSelectedDay
varvalue: Array ( [1] => 20 )

I tried to urlencode but it needs a string. Anyone has any idea?

Thanks!

If you want to pass an array through the GET or POST data, you can use [man]http_build_query/man in PHP5.

Alternatively, if you're posting it to a script that you have created (and you can modify) you can [man]serialize/man the data before sending, and then [man]unserialize/man the data upon retrieval.

Or something, I dunno, it's late.

I can't use PHP5 but I can replicate the function. However, I don't believe the problem is in PHP but basically how I can render the variable (name and value) inside a PHP post command. I don't really know if the array the PHP is detecting in the values posted is actually an array.

POST data for the control you want to emulate is as follows:

colSelectedDay%5B0%5D.x=8&colSelectedDay%5B0%5D.y=17

which is

colSelectedDay[0].x=8&colSelectedDay[0].y=17

urlencoded. The numbers can vary as they are the coordinates of the pixel that was clicked on that image. So just put that in your curl options for post data.

If you want to know what really is sent between browser and server use some tools that show what headers are sent. The above information comes from Tamper Data plugin in Firefox.

Hi, excellent pointer, thank you. I tried the plugin and it's perfect.
