Re: Re: Adding additional values to a hash of an hash ?

Unfotunately it won't work for me. I saw some code pasted on one of the posts as follows

push (@{$data{$formname}}, {
    'type'          =>  "select",
    'field_name'    =>  $selectname,
    'value'         =>  $attr->{'value'}
[download]

This would work for me but I don't know how to access the information. It seems like its being pushed into an array where the arrayname is the hash{key} ? How would one access this info? If I can get the answer to this, then I believe I am all set.

What you're talking about then is a hash of arrays of hashes. `$data{$formname}` now returns a reference to the array, and to access an individual hash table in the array you can say something like: `$data{$formname}->[0]{type}`. Basically, what you're doing is a hash lookup to grab the array reference pointed to by `$formname`, then using an array index to obtain a reference to the nested hash whose data you need to access, and then doing a normal hash lookup there on 'type'.

Hi gnangia, the code above uses a hash slice (hence the @) to assign a value to the key `$formname`. The value happens to be an anonymous hash, with keys 'type', 'field_name' and 'value', and corresponding values. What happens is that a reference to said anonymous hash is pushed onto the hash slice. To access fields in this anon hash, use code such as: `$data{$formname}->{'type'};` [download] or: `$data{$formname}{'type'};` [download] Note that the above is untested and may not work (particularly the top example might need some more curlies). Update: Never mind my rambling, I missed a pair of parentheses in your code. fever is correct in what the code is and how you access fields in it. I really must get some more sleep, or less cafeine, or both. I thought pushing stuff onto a hash slice sounded weird when I wrote it :) CU Robartes-	[reply] [d/l] [select]
