handle selects w multiple values in php 5

[Henri Schomaecker]

Hi folks,

does php 5 have a problem with html select lists which allow to choose
multiple items?

Whatever I tried I just can't get another or more than the last item
selected in the list.
Even if I select multiple items, a print_r($_POST) just shows the last
selected item, and not a array of all selected values.

Thanks very much for every hint,
yours Henri

It's not changed since PHP4 - the trick is to put [] after the name, e.g.

<select multiple='multiple' name='something[]'>

The [] causes PHP to form an array from the data; without it, the last value
overwrites the previous ones.

Try using name="somevar[]" - certainly with checkboxes, this populates
multiple values into the array, should work with select lists too...

Besides the recommendations of Andy and Matt, you can also enable the
always_populate_raw_post_data directive in your php.ini file.

After doing this, you can use your selects as before and will find the
posted data in the $HTTP_RAW_POST_DATA variable in the following format:

sel=A&sel=B&sel=C
