Does getArray('fieldname') work for you? I'm having problems getting the list of values of a group of checkboxes using . $wgRequest->getArray('fieldname'), it only returns the last element.

For instance, I have a search form with with a group of checkboxes e.g. <input type="checkbox" value="Category1" name="categories" /> <input type="checkbox" value="Category2" name="categories" />

When the form is submitted via GET, the resulting URL has: categories=Category1&categories=Category2

in my extension, I use

$category_list = array(); $category_list = $wgRequest->getArray('categories'); $categoryString = join(",", $category_list);

echo $categoryString; // Prints out 'Category2'

Any obvious error in my approach?

Thanks,

-Carlos

Hi,

I've a litte question:

$wgRequest->getVal('_naw_title') result nothing, when post-name="_naw_title[]".

What's going wrong

WebRequest::getVal() returns a string or null. This protects against type errors from malicious submissions passing unexpected arrays.

If you're dealing explicitly with an array parameter, use $wgRequest->getArray() to enforce an array-or-null return.

Daniel, Excellent...it works! Thanks so much for your help and the coding tips.

Your array command is ok. But you're not using the right name. You need to use name="categories[]" in the inputs.

So for the checkboxes:

<input type="checkbox" value="Category1" name="categories[]" /> <input type="checkbox" value="Category2" name="categories[]" />

And the extension code stays the same:

$category_list = array(); $category_list = $wgRequest->getArray('categories'); $categoryString = join(",", $category_list);

Though... personally... You're using to much pointless code. (Also, it's implode, not join.) (And you're mixing 2 types of naming styles, camelCase and underscore separated) Here's how I'd do it. $categoryList = implode( ",", $wgRequest->getArray( 'categories', array() ) ); Those extra lines are useless. You'll also end up with some bad errors. (The first line is useless because it's always overridden. The second line can return null [Which you tried to fix with the first line but failed because you need a default]. And the last line uses a improper function.)
