HTML Lists/Menus - Submitting multiple options with PHP

danindublin

I've been trying to pull a list of variables between two pages with no luck. I'm just using the basic $_GET["X"]; (where X is the name of the list). When I make multiple selections, it only gives me the last one as output.

Anyone got any ideas?

Thanks in advance.

The issue with the multiple select is the way that the browser posts or gets the variables.

For example, if you have a select called "mySelect", and someone has selected three of the values from it, the the query string in the get, will look a little like this:

mypage.php?mySelect=5&mySelect=7&mySelect=18

When the variables are passed to PHP, it only sees one value for mySelect - the last one, because the previous two are overwritten.

You need to rename the variable to include brackets at the end, so mySelect[]. This tells PHP to create an array called "mySelect", and every time a value is added to "mySelect[]", PHP adds it to the end of the array.

So then you just access it as $_GET[0], etc.

Hi Seamus,

Thanks for your help, seems to have go me a little down the road but havent got further than the first value.

//Select Section

<select name="s1" size="1" multiple="multiple" class="lst2" id="s1">
<option>Mr Ape</option>
<option>Mr Bird</option>
<option>Mr Cat</option>
<option>Mr Dog</option>
<option>Mr Elephant</option>
<option>Mr Fish</option>
</select>


//Attempt A - Seems to just add one char at a time until it gets to the end of the first string, then goes blank

$val .= $_GET[0];
$val .= $_GET[1];
$val .= $_GET[2];
$val .= $_GET[3];
$val .= $_GET[4];
$val .= $_GET[5];

//Attempt B - Only returns the last string

$val .= "Start A<br/>";
$val .= $_POST["s1"][0];
$val .= "<br/>Get value from 0<br/>";
$val .= $_POST["s1"][1];
$val .= "<br/>Get value from 1<br/>";
$val .= "Finished A<br/>";

You're still not creating the array

<select name = "s1[]"
