PHP get values from hidden input fields
Hi Expert,
I like to retreive a variating number of values from An external page and store them in a array.
I belive I'm allmost there but I can't get the array to print its content.
and I only need the value's to be loaded on the array without the HTML.
The source page looks like this:
The data retreiving site :
Now I get this error:
"Catchable fatal error: Object of class DOMElement could not be converted to string in retreive.php on line 29"
line 29 is the last echo line in the loop

How sure are you that the test data (first code snippet) is actually representative of the genuine article?

Hi Ray,
I don't understand your question/point?
I did discover the error was wrong.
It should be :
Warning: DOMDocument::saveHTML() expects exactly 0 parameters, 1 given in line 29

I'll be glad to try to show you the code; just want to be sure that I'm using accurate test data. The sample looks pretty hypothetical. Can you please post a link to the actual URL you want to read with cURL?

Great, thanks. I'll see what I can do with it and post back with the results.
